Böhringer and Patrick E.P. Jochem. Measuring the immeasurable — A survey of sustainability indices

Sustainability indices for countries provide a one-dimensional metric to valuate country-specific information on the three dimensions of sustainable development: economic, environmental, and social conditions. At the policy level, they suggest an unambiguous yardstick against which a country's development can be measured and even a cross-country comparison can be performed. This article reviews the explanatory power of various sustainability indices applied in policy practice. We show that these indices fail to fulfill fundamental scientific requirements making them rather useless if not misleading with respect to policy advice.

Christian Rammel, Sigrid Stagl and Harald Wilfing. Managing complex adaptive systems — A co-evolutionary perspective on natural resource management

The overexploitation of natural resources and the increasing number of social conflicts following from their unsustainable use point to a wide gap between the objectives of sustainability and current resource management practices. One of the reasons for the difficulties to close this gap is that for evolving complex systems like natural and socio-economic systems, sustainability cannot be a static objective. Instead sustainable development is an open evolutionary process of improving the management of social–ecological systems, through better understanding and knowledge. Therefore, natural resource management systems need to be able to deal with different temporal, spatial and social scales, nested hierarchies, irreducible uncertainty, multidimensional interactions and emergent properties. The co-evolutionary perspective outlined in this paper serves as heuristic device to map the interactions settled in the networks between the resource base, social institutions and the behaviour of individual actors. For this purpose we draw on ideas from complex adaptive systems theory, evolutionary theory and evolutionary economics. Finally, we outline a research agenda for a co-evolutionary approach for natural resource management systems.

Diego Azqueta and Daniel Sotelsek. Valuing nature: From environmental impacts to natural capital

Economic valuation of natural and environmental assets is now a well established practice. Economic analysis provides several methods for discovering the impact on social welfare associated with changes in the ability of these assets to provide different goods and services. In general terms, these valuation exercises have been performed in the framework of Environmental Impact Assessment or, more generally, Cost Benefit Analysis. There is, however, an increasing demand nowadays to go beyond this framework and to value natural capital (natural resource stocks, land and ecosystems) as such. There are two main reasons for this new demand. On the one hand, sustainability requires that proper account should be taken of capital depreciation and, therefore, there is a need to value natural capital changes. This valuation process, nevertheless, only makes sense when some kind of substitution between natural and other forms of capital is allowed. On the other hand, there is also an increasing tendency to demand that the stock of natural capital present in a given territory be valued, either to discover one of the main components of social wealth or to help adequately plan changes in land use. Yet, whereas conventional valuation methods are probably adequate to fulfill the first task, this is less true in the case of the second, while even more difficulties arise in connection with the third one. Even if at first sight the process appears conceptually identical, these tasks are of a different order of magnitude, as the experience of both the World Bank and the Statistics Division of the United Nations in this respect clearly shows.

Randall Bluffstone. Privatization and contaminated site remediation in Central and Eastern Europe: Do environmental liability policies matter?

This paper examines the effects on site remediation decisions after state-owned firms have been privatized of providing environmental information to potential investors and undertaking site remediation planning prior to privatization. The literature suggests that to minimize distortions created by uncertain environmental problems, governments should invest in environmental information for potential investors, inventory problems and develop plans for remediation. One of the believed benefits is a higher probability of site remediation, because with uncertainty resolved potential conflicts after privatization are less likely. Few countries in Central Europe, which has experienced both environmental problems and privatization on enormous scales, have adopted this advice. Using firm-level data, empirical analysis is presented, which suggests providing only information to investors is insufficient to spur remediation. Inventorying site contamination and planning remediation prior to privatization is a much more effective measure. Combining provision of information with remediation planning is found to be the most powerful policy package for encouraging remediation.

Dominic Moran, Alistair McVittie, David J. Allcroft and David A. Elston. Quantifying public preferences for agri-environmental policy in Scotland: A comparison of methods

his paper compares two methods for determining policy priorities for reform of Scottish agricultural support. Multifunctional agriculture attempts to establish a new balance between traditional commodity support and payment for the production of non-market goods and services that are increasingly demanded by the public. Supplying non-market goods presents particular problems for optimal policy design, not least the elicitation of consumer demand for those goods. From public focus groups, a range of attributes was derived as central to the Scottish public’s preferences for future agri-environmental reform. This information was then combined in two separate survey methods using the Analytical Hierarchy Process (AHP) and choice experiments (CE). Both applications suggest that the public has defined preferences and a willingness to pay (using general income taxation) to affect changes beyond the status quo, and that policy payments should be targeted towards both environmental and social benefits. The divergent preference orderings derived from the alternative methods can be considered in the light of previous methodological debates on question framing, bounded rationality and respondent uncertainty. We speculate about the validity of alternative methodologies for informing particular policy questions.

Neha Khanna and Florenz Plassmann. Total factor productivity and the Environmental Kuznets Curve: A comment and some intuition

Chimeli and Braden [Chimeli, Ariaster B., Braden, John B., 2005. Total factor productivity and the Environmental Kuznets Curve. Journal of Environmental Economics and Management 49, 366–380] derive a necessary and sufficient condition under which inter-country differences in total factor productivity can yield an Environmental Kuznets Curve. They argue that their results emphasize the importance of differences in total factor productivity across countries as well as the need for decreasing returns to scale in pollution-abating technologies for the existence of an Environmental Kuznets Curve. We show that their Proposition 1 is equivalent to Proposition 2 in Lieb [Lieb, Christoph M., 2002. The Environmental Kuznets Curve and satiation: a simple static model. Environment and Development Economics 7, 429–448]. This implies that, even in Chimeli and Braden's model, contemporaneous changes in the marginal rate of substitution between environmental quality and consumption on the demand side and the marginal rate of transformation between these goods on the supply side drive the pollution–income relationship. This is a very general condition that does not rely on either differences in total factor productivity or decreasing returns to scale in abatement, and which is widely applicable.

Karl W. Steininger, Birgit Friedl and Brigitte Gebetsroith. Sustainability impacts of car road pricing: A computable general equilibrium analysis for Austria

Nationwide car road pricing schemes are discussed across Europe. We analyse the impacts of such schemes with respect to environmental, economic and social indicators of sustainability, also quantifying the trade-offs among these three dimensions under different charging principles and revenue recycling options. In our analysis we employ a computable general equilibrium (CGE) approach, develop a modelling structure for private transport and provide detailed empirical analysis for the case of Austria. Regarding the social dimension, it has often been argued that poorer households (and commuters) would have to bear a disproportionate share of the road pricing burden. We find the contrary, i.e. a stronger negative policy impact on richer households, and on a small group of intensive car users. The choice of revenue recycling is able to ameliorate the negative social and economic effects of road pricing, without reversing the desired positive environmental effects. For political feasibility, questions of distributional impacts are most urgent and therefore we address them systematically within a quantitative framework.

Carlos José Caetano Bacha and Luiz Carlos Estraviz Rodriguez. Profitability and social impacts of reduced impact logging in the Tapajós National Forest, Brazil — A case study

Brazil contains the world's largest tropical rainforests, most located in the Amazon River Basin. Over the last three decades, rapid growth of this region's deforested area has had negative impacts. To minimize these impacts and maintain biodiversity, the Brazilian Government has established several national forests in the Basin. The ITTO Project, a reduced impact logging (RIL) operation, was recently carried out at one of these forests: the Tapajós National Forest, also known as Flona Tapajós. This paper evaluates the Project's profitability and its effect on local residents. The Project, which ran between 1999 and 2003, was coordinated by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA), with funding for planning and monitoring provided by the United Kingdom's Department of International Development (DFID) working through and approved by the International Tropical Timber Organization (ITTO). Treviso Agropecuária Ltda, a private logging company, carried out timber extraction on the Project site. Our evaluation found the ITTO Project to have been highly profitable for Treviso, even after their compliance with all Brazilian labor and environmental laws. This finding was based on field interviews and the examination of documents from IBAMA and Treviso. Treviso's mean internal rate of return from the Project was calculated to have been 35.79%, considerably higher than that generated by the region's farms and ranches. The ITTO Project positively impacted Project workers, providing employment and exposing them to rainforest management techniques that maximize timber production while minimizing forest destruction. The paper closes by suggesting that more of the direct and indirect benefits of new reduced impact logging projects on Brazilian national forest land need to be channeled to the local population to increase the probability of them act as capable forest custodians.

Pia Bøgelund. Making green discourses matter in policy-making: Learning from discursive power struggles within the policy area of car taxation

This paper is about stability and change in the policy-making discourse of a traditional neoclassical policy area, the area of car taxation. Stability is here related to the unquestioned continuation of a traditional neoclassical economics perspective in policy-making, whereas change is related to the introduction and impact of environmental concerns. The aim of the paper is to investigate, what makes green discourses matter in traditional policy-making. It is based on an in-depth study of policy-making processes related to car taxation in two environmental front-runner countries, Sweden and Denmark.

Making green discourses matter in policy-making is an important contemporary environmental challenge. Therefore, as Tian Shi argues, we need more research into the institutional setting of the policy-making process. Ecological economics as a policy science has to have a broad understanding of the political economic nature of the policy process. Taking this standpoint as the point of departure, the paper seeks to uncover questions such as, what is the policy-making reality in which Swedish and Danish green discourses have to make a difference? How do existing neoclassical regimes react, when green actors attempt to influence policy-making from an environmental point of view? And to what extent can green discourses actually have an impact on the policy world within the area of car taxation?

The paper concludes that the traditional neoclassical economic discourse is particularly robust and resistant against alternative green discourses. Stability rather than change is the dominating picture. This does not imply that environmental concerns will not be taken into account in the future. Rather it implies that only the changes, which keep up the existing order, or enhance the narrow power-related interests of the dominating actors, will materialise more or less easily. The rest is a power struggle in which timing, coalition-building, persistence and thorough knowledge about the field in question is of importance. In this struggle change agents will also benefit from the ability to rethink dominating ways of thinking and doing in an environmentally benign way. A rethinking that is based on environmental values while at the same time holding positive visions that are ‘compatible’ with the existing dominating discourse.

Jouni Paavola. Institutions and environmental governance: A reconceptualization

This article presents the conceptual revisions needed to extend the new institutional approach to environmental governance from its current local and international domains of application to all governance solutions, including national environmental and natural resource use policies and multi-level governance solutions that are increasingly used to address global environmental change. The article suggests that environmental governance is best understood as the establishment, reaffirmation or change of institutions to resolve conflicts over environmental resources. It also explains why the choice of these institutions is a matter of social justice rather than of efficiency. The article suggests a way to understand formal and state-centered governance solutions as forms of collective ownership not unlike common property. The article demonstrates how institutional analysis can gain resolution by looking at the functional and structural tiers, organization of governance functions, and formulation of key institutional rules as key aspects of the design of governance institutions.

Alexey Voinov and Joshua Farley. Reconciling sustainability, systems theory and discounting
ages

Most definitions of sustainability imply that a system is to be maintained at a certain level, held within certain limits, into the indefinite future. Sustainability denies run-away growth, but it also avoids any decline or destruction. This sustainability path is hard to reconcile with the renewal cycle that can be observed in many natural systems developing according to their intrinsic mechanisms and in social systems responding to internal and external pressures. Systems are parts of hierarchies where systems of higher levels are made up of subsystems from lower levels. Renewal in components is an important factor of adaptation and evolution. If a system is sustained for too long, it borrows from the sustainability of a supersystem and rests upon lack of sustainability in subsystems. Therefore by sustaining certain systems beyond their renewal cycle, we decrease the sustainability of larger, higher-level systems. For example, Schumpeter's theory of creative destruction posits that in a capitalist economy, the collapse and renewal of firms and industries is necessary to sustain the vitality of the larger economic system. However, if the capitalist economic system relies on endless growth, then sustaining it for too long will inevitably borrow from the sustainability of the global ecosystem. This could prove catastrophic for humans and other species. To reconcile sustainability with hierarchy theory, we must decide which hierarchical level in a system we want to sustain indefinitely, and accept that lower level subsystems must have shorter life spans. In economic analysis, inter-temporal discount rates essentially tell us how long we should care about sustaining any given system. Economists distinguish between discount rates for individuals based on personal time preference, lower discount rates for firms based on the opportunity cost of capital, and even lower discount rates for society. For issues affecting even higher-level systems, such as global climate change, many economists question the suitability of discounting future values at all. We argue that to reconcile sustainability with inter-temporal discounting, discount rates should be determined by the hierarchical level of the system being analyzed.

Xuehong Wang, Jeff Bennett, Chen Xie, Zhitao Zhang and Dan Liang. Estimating non-market environmental benefits of the Conversion of Cropland to Forest and Grassland Program: A choice modeling approach

The non-market values of the environmental benefits derived from the Conversion of Cropland to Forest and Grassland Program (also known as the Grain for Green Program and the Sloped Land Conversion Program) in the Loess Plateau region of North West China were estimated using choice modeling both on-site in Xi'an and Ansai and off-site in Beijing. Separate choice models were estimated for the three sites and the results compared. Significant differences were found between the implicit price estimates derived from the multinomial logit (MNL) model and the random parameter logit (RPL) model for some environmental attributes. Based on the results from the RPL models, the average willingness to pay per respondent household in Beijing was CNY882.56 (USD109.44) each year for the environmental improvements on the Loess Plateau provided by the Program, a payment level significantly higher than the comparable estimates of CNY342.56 (USD42.48) in Xi'an and CNY388.08 (USD48.12) in Ansai.

Minna Halme, Markku Anttonen, Mika Kuisma, Nea Kontoniemi and Erja Heino. Business models for material efficiency services: Conceptualization and application

Despite the abundant research on material flows and the growing recognition of the need to dematerialize the economy, business enterprises are still not making the best possible use of the many opportunities for material efficiency improvements. This article proposes one possible solution: material efficiency services provided by outside suppliers. It also introduces a conceptual framework for the analysis of different business models for eco-efficient services and applies the framework to material efficiency services. Four business models are outlined and their feasibility is studied from an empirical vantage point. In contrast to much of the previous research, special emphasis is laid on the financial aspects. It appears that the most promising business models are ‘material efficiency as additional service’ and ‘material flow management service’. Depending on the business model, prominent material efficiency service providers differ from large companies that offer multiple products and/or services to smaller, specialized providers. Potential clients (users) typically lack the resources (expertise, management's time or initial funds) to conduct material efficiency improvements themselves. Customers are more likely to use material efficiency services that relate to support materials or side-streams rather than those that are at the core of production. Potential client organizations with a strategy of outsourcing support activities and with experience of outsourcing are more keen to use material efficiency services.

Giuseppe Di Vita. Exhaustible resources and secondary materials: A macroeconomic analysis

In this paper we have developed an endogenous growth model to deal with exhaustible resources and secondary materials together, under the assumptions that these two inputs are, or are not, technologically perfect substitutes of each other, in order to compare the results obtained under both hypotheses. We highlight the implication of these two assumptions on the rate of growth of total output and upon the flow of exhaustible resources extracted. There are also some other interesting findings related to the spill-over on welfare of the waste recycling process, and the dynamics of shadow prices of both inputs considered. Finally, some implications on Hotelling's rule also emerge in our analytical framework.

Jeffrey A. Michael.Episodic flooding and the cost of sea-level rise

Previous studies of the cost of sea-level rise focus on the economic loss to inundated property rather than increased damage from episodic flood events to non-inundated property above sea level. This study uses a unique GIS database of three geographically diverse Chesapeake Bay communities that includes 1-ft elevation contours from remote sensing data, local tax assessment records, and aerial photographs of property location. Hedonic property value models estimate the loss from complete inundation, closely following the methodology of previous studies. Increased damage from episodic flooding is estimated using elevation-rated, actuarially fair flood insurance rates. Using a 3-ft sea-level rise over 100 years scenario, damage from episodic flooding averages 9 times the estimated loss from complete inundation, and is an average of 28 times greater under a 2-ft sea-level rise scenario. Although the study areas are not representative of all coastal areas, the results suggest that current studies may substantially underestimate the cost of sea-level rise.

Sugata Marjit, Saibal Kar and Hamid Beladi. Protectionary bias in agriculture: A pure economic argument

Empirical evidence suggests that the agricultural sector in the developed countries has enjoyed a greater degree of protection than the import-competing manufacturing sectors. Usually this is attributed to strong farm lobbies and hence on political factors. We provide a theoretical model and a possible explanation of this phenomenon based on purely economic arguments. Two importables are accommodated in a three-good three-factor model of trade and production, one is a labor-intensive manufacturing good and the other is an agricultural commodity. This captures the trade pattern of a typical industrialized country with an agricultural sector such as Europe and the USA. We show that uniform tariffs in agriculture and labor-intensive manufacturing will definitely hurt the land owners in real terms and may reduce their absolute return. Hence, if there has to be protection, it has to be biased in favor of agriculture.

Arno J. van der Vlist, Cees Withagen and Henk Folmer.Technical efficiency under alternative environmental regulatory regimes: The case of Dutch horticulture

We consider the performance of small and medium sized enterprises in Dutch horticulture under different environmental policy regimes across time. We address the question whether technical performance differs under these alternative regulatory regimes to test Porter's hypothesis that stricter environmental regulation reduces technical inefficiency. For this purpose, we use a stochastic production frontier framework allowing for inclusion of policy variables to measure the effect of alternative environmental policy regimes on firms' performance. The main result is that stricter environmental policy regimes have indeed reduced technical inefficiencies in Dutch horticulture. The estimation results indicate amongst others that the 1997 agreement on energy, nutrient and pesticides use enhances technical efficiency. Firms under the strict environmental policy regime are found to be more technically efficient than those under a lax regime, thereby supporting the claims by Porter and Van der Linde (Porter, M., Van der Linde, C., 1995. Green and Competitive: Ending the stalemate. Harvard Business Review 73, pp. 120–137) concerning Dutch horticulture.

Jesus Ramos-Martin, Mario Giampietro and Kozo Mayumi.On China's exosomatic energy metabolism: An application of multi-scale integrated analysis of societal metabolism (MSIASM)

The methodology of multi-scale integrated analysis of societal metabolism (MSIASM) is applied to the analysis of the recent evolution of Chinese economy. This paper has two goals: (1) to show the MSIASM scheme is effective in handling in an integrated way different types of data, mixing extensive and intensive variables, on different levels; and (2) to provide a multi-scale integrated analysis of the trajectory of development of China. The quality of possible scenarios is checked by identifying constraints affecting their feasibility and by characterizing them in relation to different dimensions and scales of analysis.

This entails 4 tasks: (i) identifying a set of benchmarks that makes it possible to compare different characteristics and features of China to other countries and to the average values calculated for the world level; (ii) explaining the differences found over the selected set of benchmarks, by looking at the characteristics of the various sub-sectors of Chinese economy; (iii) understanding existing trends and future feasible paths of China's development by studying the existence of reciprocal constraints between the whole economy and its compartments; and (iv) examining possible future scenarios of development for China.

Bernd Meyer, Martin Distelkamp and Marc Ingo Wolter.Material efficiency and economic-environmental sustainability. Results of simulations for Germany with the model PANTA RHEI

Based on empirical evidence, the paper discusses the impact of a consulting and information program for the improvement of material productivity with regard to economic and environmental targets for Germany. The instrument used in the analysis is the integrated economic-environmental model PANTA RHEI, which is parameterized econometrically. The paper presents the model and shows in a baseline forecast that without policy changes, sustainability will be violated in both the economic and the environmental dimensions. This applies to the latter particularly with regard to land use and material consumption. The alternative simulation that introduces a consulting and information program for the improvement of material productivity yields a win–win result: growth rates of GDP and employment are rising, the public debt is reduced, and material consumption is much lower than in the baseline and remains at the actual level, which means that a decoupling of growth and material consumption is possible.

Esther Velázquez.Water trade in Andalusia. Virtual water: An alternative way to manage water use

The main idea of this paper is to analyse the relationships between the productive process and the commercial trade with water resources used by them. For that, the first goal is to find out, by means of the estimation of virtual water, the exported crops which have the highest water consumption. Similarly, we analyse the crops that are imported and therefore, might contribute to save water. The second objective is to put forward new ways to save water by means of the virtual water trade.

This first conclusion contradicts not only the comparative advantages theory but also the environmental sustainability logic. The previous conclusion is derived from the great exports of water via potatoes and vegetables, and also via citrus fruit and orchards; and, on the other hand, from the imports, such as cereals and arable crops, with lower water requirements. The second conclusion affirms as Andalusia utilises large amounts of water in its exports, and in turn, it does not produce goods with low water requirements, the potential saving would be very significant if the terms of our trade were the other way round. We are convinced that the agricultural sector must modify the use of water to a great extent in order to reach significant water savings and an environmental sustainability path.

Luke M. Brander, Pieter Van Beukering and Herman S.J. Cesar.The recreational value of coral reefs: A meta-analysis

Coral reefs are highly productive ecosystems that provide a variety of valuable goods and services, including recreational opportunities. The open-access nature and public good characteristics of coral reefs often result in them being undervalued in decision making related to their use and conservation. In response to this, there now exists a substantial economic valuation literature on coral reefs. For the purposes of conducting a meta-analysis of this literature, we collected 166 coral reef valuation studies, 52 of which provided sufficient information for a statistical meta-analysis, yielding 100 separate value observations in total. Focusing on recreational values, we use US$ per visit as the dependent variable in our meta-analysis. The meta-regression results reveal a number of important factors in explaining variation in coral reef recreational values, notably the area of dive sites and the number of visitors. Different valuation methods are shown to produce widely different values, with the contingent valuation method producing significantly lower value estimates. Using a multi-level modelling approach we also control for authorship effects, which proves to be highly significant in explaining variation in value estimates. We assess the prospects for using this analysis for out-of-sample value transfer, and find average transfer errors of 186%. We conclude that there is a need for further high-quality valuation research on coral reefs.

Yoh Iwasa, Tomoe Uchida and Hiroyuki Yokomizo.Nonlinear behavior of the socio-economic dynamics for lake eutrophication control

To succeed in combating lake eutrophication, cooperation of local inhabitants, small factories, and farmers in reducing phosphorus discharge is very important. But the willingness of each player to cooperate would depend on the cooperation of other players and on the level of environmental concern of the society in general. Here we study the integrated dynamics of people's choice of behavior and the magnitude of eutrophication. Assumptions are: there are a number of players who choose between alternative options: a cooperative and environment-oriented option is more costly than the other. The decision of each player is affected by “social pressure” as well as by economical cost of the options. The lake pollution increases with the total phosphorus released, and a high pollution level in the lake would enhance the social pressure. The model includes a positive and a negative feedback loops which create diverse dynamical behavior. The model often shows bistability — having an equilibrium with a high level of cooperation among people and clean water, and the other equilibrium with low cooperation and polluted water, which are simultaneously stable. The model also shows fluctuation between a high and a low levels of cooperation in alternating years, cycle with a longer periodicity, or chaotic fluctuation. Conservatism of people stabilizes the system and sometimes helps maintaining cooperation. The system may show unexpected parameter dependence — the improved phosphorus removing efficiency might make water more polluted if it causes the decline in the environmental concern and cooperation among people.

Jordi Roca and Mònica Serrano.Income growth and atmospheric pollution in Spain: An input–output approach

The relationships between economic growth and environmental pressures are complex. Since the early nineties, the debate on these relationships has been strongly influenced by the Environmental Kuznets Curve hypothesis, which states that during the first stage of economic development environmental pressures increase as per capita income increases, but once a critical turning point has been reached these pressures diminish as income levels continue to increase. However, to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in Spain. The aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in Spain. In order to obtain empirical outcomes for this analysis, we adopt an input–output approach and use NAMEA data for the nine pollutants. First, we undertake a structural decomposition analysis for the period 1995–2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions. And second, we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure.

Eckhard Janeba.International trade and consumption network externalities

This paper studies the effects of trade liberalization in the presence of consumption network externalities. The framework is applicable to the choice of network products and sheds light on the debate on globalization and culture. In an extended Ricardian model of international trade the paper shows that: (i) trade is not Pareto inferior to autarky if the free trade equilibrium is unique; (ii) trade is not Pareto superior to autarky if both countries are diverse (network competition) under free trade, but can be if each country is homogenous (network monopoly); (iii) and when multiple free trade equilibria exist everybody in a country can lose from free trade if that country is homogenous under autarky. Consumers of imported network goods tend to gain, while consumers of exported network goods tend to lose from trade liberalization.

Adriaan Kalwij and Arjan Verschoor.Not by growth alone: The role of the distribution of income in regional diversity in poverty reduction

This study examines the role of the distribution of income in determining the responsiveness of poverty to income growth and changes in income inequality using panel data of 58 developing countries for the period 1980–1998. We show that the large cross-regional variation in the capacity of income growth to reduce poverty, i.e. the income elasticity, is largely explained by differences in the initial distribution of income and present region and time specific estimates of the income and Gini elasticities of poverty. We find that the income elasticity of poverty in the mid-1990s equals -1.31 on average and ranges from -0.71 for Sub-Saharan Africa to -2.27 for the Middle East and North Africa, and that the Gini elasticity of poverty equals 0.80 on average and ranges from 0.01 in South Asia to 1.73 in Latin America. Furthermore we show that while differing income growth rates account for most of the regional diversity in poverty trends, the additional impact of differences across regions in rates of inequality change and income and inequality elasticities of poverty is almost always significant and far too large to be ignored, most notably so in Eastern Europe and Central Asia.

Hiau Looi Kee and Bernard Hoekman.Imports, entry and competition law as market disciplines

Numerous countries have adopted or strengthened competition laws in the past two decades. At the same time, domestic industries in most countries are facing ever more intense pressure from imports. In this paper we study the impact of competition law on domestic competition for a large number of countries over time, controlling for the presence of imports and the number of domestic firms. We find that while industries that have higher import exposure or larger numbers of domestic firms tend to be more competitive, the direct effect of competition law on competition is insignificant. However, we also find that industries that operate under a competition law tend to have a larger number of domestic firms. This suggests that competition laws may have an indirect effect on domestic competition by promoting entry.

Patrick W. Schmit.Optimal selling strategies when buyers may have hard information

Consider a revenue-maximizing seller who can sell an object to one of n potential buyers. Each buyer either has hard information about his valuation (i.e., evidence that cannot be forged) or is ignorant. The optimal mechanism is characterized. It turns out that more ignorance can increase the expected total surplus. Even when the buyers are ex ante symmetric, the object may be sold to a buyer who does not have the largest willingness-to-pay. Nevertheless, an additional buyer increases the expected total surplus in the symmetric case, whereas more competition can be harmful if there are ex ante asymmetries.

Arno Riedl and Frans van Winden.An experimental investigation of wage taxation and unemployment in closed and open economies

We investigate experimentally the economic effects of wage taxation to finance unemployment benefits for a closed economy and an international economy. The main findings are the following. (i) There is clear evidence of a vicious circle in the dynamic interaction between the wage tax and unemployment. (ii) Employment is boosted by budget deficits but subsequent tax rate adjustments to balance the budget lead to employment levels substantially lower than theoretically predicted. (iii) A sales risk for producers due to price uncertainty on output markets appears to cause a downward pressure on factor employment. For labor the wage tax exacerbates this adverse effect.

Mark Melatos and Alan Woodland. Endogenous trade bloc formation in an asymmetric world

This paper investigates how variations in endowments and the structure of preferences impact on the coalition formation decisions of asymmetric countries. There exist relatively few general results on the relationship between country characteristics and trade bloc formation. Here, new light is shed on this issue by systematically simulating bloc formation and by explicitly analysing the blocking behaviour of coalitions. A general equilibrium model of world trade is implemented with equilibrium coalition formation being modelled using the equilibrium concept of the core. It is found that global free trade is observed when all countries are similar. Customs unions tend to form between countries with ‘adjacent’ consumer preferences or with ‘adjacent’ endowments of their export commodity. Finally, in contrast to the existing literature but consistent with observed behaviour, it is found that free trade areas often Pareto dominate customs unions, provided consumer preferences differ sufficiently.

Silja Göhlmann and Roland Vaubel. The educational and occupational background of central bankers and its effect on inflation: An empirical analysis

We test the hypothesis that the inflation preferences of central bankers depend on their educational and/or occupational background. In a panel data analysis for the euro area and eleven countries since 1973, we explain inflation either by the weights with which the educational and occupational characteristics of the 391 council members were represented in the various central bank councils or by the education or occupation of the median council members. Control variables are added. Our most robust result is that former members of the central bank staff prefer significantly lower inflation rates than former politicians do.

Mattias Ganslandt and Keith E. Maskus. Vertical distribution, parallel trade, and price divergence in integrated markets

We develop a model of vertical pricing in which an original manufacturer sets wholesale prices in two markets that are integrated at the distributor level by parallel imports (PI). The manufacturing firm needs to set these two prices to balance three competing interests: restricting competition in the PI-recipient market, avoiding resource wastes due to actual trade, and reducing the double-markup problem in the PI-source nation. These tradeoffs imply the counterintuitive result that retail prices could diverge as a result of declining trading costs, even as the volume of PI increases. Thus, in some circumstances it may be misleading to think that permitting PI is an unambiguous force for price integration.

Jacques Melitz. North, South and distance in the gravity model

t is generally assumed that distance in the gravity model strictly reflects frictions impeding bilateral trade. However, distances North–South could also reflect differences in factor endowment that provide opportunities for profitable trade. This paper investigates the hypothesis that if we control for distance in the ordinary sense, differences North–South promote international trade. The hypothesis receives ample support. Moreover, the significance of differences North–South survives a battery of robustness tests, concerning period, distinctions between differences in latitude North–North, North–South and South–South, and controls for other measures of differences in factor endowment, such as differences in per capita output and differences in average temperature, rainfall, and seasonal range in temperature. The impact of differences North–South on bilateral trade has also been falling. This decline, in turn, might be partly responsible for the weakening of the influence of distance that has been occurring since World War II. This last hypothesis receives confirmation as well. Finally, the paper examines the impact of internal distance and remoteness on trade. Since both variables are country-specific, this is done by studying their impact on the country fixed effects themselves in the earlier estimates. Internal distance turns out to have a far greater impact than remoteness—by an order of 10.

Sourafel Girma, Richard Kneller and Mauro Pis. Do exporters have anything to learn from foreign multinationals?

International technology diffusion through FDI has been examined mainly at macro or industry level whereas micro studies have been concerned mostly with spillovers. Using recent data on the UK manufacturing firms, this paper uncovers evidence that acquisition FDI is an important channel of direct technology transfer from foreign multinationals to domestic exporters. This finding accords with the prediction of the internalisation theory of FDI which postulates that multinational firms transfer a range of intangible proprietary assets to their affiliates.

Elissaios Papyrakis and Reyer Gerlagh.Resource abundance and economic growth in the United States

It is a common assumption that regions within the same country converge to approximately the same steady-state income levels. The so-called absolute convergence hypothesis focuses on initial income levels to account for the variability in income growth among regions. Empirical data seem to support the absolute convergence hypothesis for US states, but the data also show that natural resource abundance is a significant negative determinant of growth. We find that natural resource abundance decreases investment, schooling, openness, and R&D expenditure and increases corruption, and we show that these effects can fully explain the negative effect of natural resource abundance on growth.

Paul R. Bergin, Hyung-Cheol Shin and Ivan Tchakarov.Does exchange rate variability matter for welfare? A quantitative investigation of stabilization policies

This paper studies what degree of exchange rate stabilization is optimal for several types of open economies. This is accomplished through a quantitative evaluation of optimal monetary policy rules in a two-country sticky-price model. First, a calibrated benchmark model with incomplete asset markets supports past conclusions from simpler models, emphasizing inflation stabilization rather than exchange rate stabilization. It also highlights that the utility gains from optimal stabilization policy are small. Second, while an economy extended to include consumer habits implies greater sensitivity by households to consumption variability, it has only minor effects on the benchmark conclusions and benefits. Finally, these conclusions are altered under an alternative environment where international asset markets exhibit asymmetry in the form of “original sin.” Such countries can benefit from policies that aggressively stabilize the exchange rate, with utility gains larger than the previous cases.
