    Allocative and Informational Externalities in Auctions and Related Mechanisms

    We study the effects of allocative and informational externalities in (multi-object) auctions and related mechanisms. Such externalities naturally arise in models that embed auctions in larger economic contexts. In particular, they appear when there is downstream interaction among bidders after the auction has closed. The endogeneity of valuations is the main driving force behind many new, specific phenomena with allocative externalities: even in complete information settings, traditional auction formats need not be efficient, and they may give rise to multiple equilibria and strategic non-participation. But, in the absence of informational externalities, welfare maximization can be achieved by Vickrey-Clarke- Groves mechanisms. Welfare-maximizing Bayes-Nash implementation is, however, impossible in multi-object settings with informational externalities, unless the allocation problem is separable across objects (e.g. there are no allocative externalities nor complementarities) or signals are one-dimensional. Moreover, implementation of any choice function via ex-post equilibrium is generically impossible with informational externalities and multidimensional types. A theory of information constraints with multidimensional signals is rather complex, but indispensable for our study

    Biodiversity Conservation on Private Lands: Information Problems and Regulatory Choices

    Get PDF
    This survey paper examines various information insufficiencies in biodiversity conservation and their impact of regulatory choices. We surveyed the literature in the field and identified four major types of informational insufficiencies in making efficient biodiversity conservation decisions: 1) biological uncertainty 2) natural uncertainty 3) individual information, and 4) monitoring problem. The consequences of these four types of information insufficiencies on the choice of regulatory tools are explored. We discuss in this context three types of regulatory tools: land takings, environmental fees/charges, and contracts. The efficiency of each type of regulatory tools is shown dependent on the specific informational constraints that the regulatory faces.Biodiversity conservation, Information, Regulatory tools

    Licensing of a lower-cost production process to an asymmetric Cournot duopoly

    Get PDF
    An outside inventor of a new production process seeks to license it to Cournot duopolists which have unequal ex ante costs. Distinguishing "leading-edge" innovations (new cost below both firms' costs) from "catch-up" innovations (new cost between the two firms' costs), we compare the equilibria of two license-selling mechanisms: exclusive license auction and non-exclusive price-setting. In contrast to the often-studied case of an innovation that reduces the cost of any licensee by the same amount, we show that licensing of a new process may attenuate the ex ante cost asymmetry, allow the inefficient firm to leapfrog its competitor, and raise the licensee's net profits.cost-reducing innovation; technology licensing

    The Emergence of Large Shareholders in Mass Privatized Firms: Evidence from Poland and the Czech Republic

    Get PDF
    Mass privatization offers a particularly suitable framework to study the change in ownership concentration as the extent of change is unusual for a stable market economy. Focusing on two different mass privatization schemes in two transition economies, Poland and the Czech Republic, we find that despite important differences in the design of the two programmes and despite different quality of legal and regulatory framework, ownership structure in the two countries has rapidly evolved and the emerging ownership patterns are remarkably similar. This suggests that private benefits of control are large and the quality of investor protection regime is low in both countries. However, looking at the relationship between the change in ownership concentration and firm performance, we find an interesting difference between the two countries: in the Czech Republic the increase in ownership concentration seems to be less likely in poorly performing firms while in Poland the quality of past performance does not affect investors' willingness to increase their holdings. This effect may be interpreted in the light of the theory stressing the importance of the quality of investors' protection. It could be argued that if Czech investors are more risk averse and more concerned with diversification this is largely due to the weakness of the legal protection they face.Ownership concentration, Mass privatisation, Corporate governance, Transition

    Cities and Cultures

    We investigate the existence of wage premium due to cultural diversity across US cities. Using census data from 1970 to 1990, we find that at the urban level richer diversity is systematically associated with higher average nominal wages for white US-born males. We measure cultural diversity in a city using the variety of languages spoken by city-residents. While the positive correlation between wages and diversity survives a battery of robustness checks, it seems to be larger once foreign cultures have been assimilated. Finally, instrumental variable estimation hints at causation going from diversity to wages. Comparing real and nominal wages across cities, we interpret these results as evidence that diversity enhances productivity.Cultural diversity, Productivity, Wages, Metropolitan areas

    The Copula Approach to Sample Selection Modelling: An Application to the Recreational Value of Forests

    Get PDF
    The sample selection model is based upon a bivariate or a multivariate structure, and distributional assumptions are in this context more severe than in univariate settings, due to the limited availability of tractable multivariate distributions. While the standard FIML estimation of the selectivity model assumes normality of the joint distribution, alternative approaches require less stringent distributional hypotheses. As shown by Smith (2003), copulas allow great flexibility also in FIML models. The copula model is very useful in situations where the applied researcher has a prior on the distributional form of the margins, since it allows separating their modelling from that of the dependence structure. In the present paper the copula approach to sample selection is first compared to the semiparametric approach and to the standard FIML, bivariate normal model, in an illustrative application on female work data. Then its performance is analysed more thoroughly in an application to Contingent Valuation data on recreational values of forests.Contingent valuation, Selectivity bias, Bivariate models, Copulas

    Does Endogenous Technical Change Make a Difference in Climate Policy Analysis? A Robustness Exercise with the FEEM-RICE Model

    Get PDF
    Technical change is generally considered the key to the solution of environmental problems, in particular global phenomena like climate change. Scientists differ in their views on the thaumaturgic virtues of technical change. There are those who are confident that pollution-free technologies will materialize at some time in the future and will prevent humans from suffering the catastrophic consequences of climate change. Others believe that there are inexpensive technologies already available and argue the case for no-regret adoption policies (e.g. subsidies). Others again believe that the process of technological change responds to economic stimuli. These economic incentives to technological innovation are provided not only by forces that are endogenous to the economic system, but also by suitably designed environmental and innovation policies. In this paper, we consider and translate into analytical counterparts these different views of technical change. We then study alternative formulations of technical change and, with the help of a computerized climate-economy model, carry out a number of optimization runs in order to assess what type of technical change plays a role (assuming it does) in the evaluation of the impact of climate change and of the policies designed to cope with it.Climate policy, Environmental modeling, Integrated assessment, Technical change

    The case for tradable remedies in WTO dispute settlement

    Get PDF
    In response to concerns over the efficacy of the WTO dispute settlement system, especially in regard to its use by developing countries, Mexico has tabled a proposal to introduce tradable remedies within the Dispute Settlement Understanding. The idea is that a country that has won cause before the WTO, and who is facing non-implementation by the author of the illegal act but feels that its own capacity to exercise its right to impose countermeasures is unlikely to lead to compliance, can auction off that right. The attractiveness of this idea is that it offers an additional possibility to injured WTO members to get something from the dispute settlement mechanism without putting into question the legal nature of the existing contract, that is, the predominantly decentralized system of enforcement in the WTO. Examining all disputes brought to the WTO since its inception, the authors find some support for Mexico's perception that developing countries face a practical problem when they attempt to carry through with effective retaliation within the WTO system. And based on the formal results of Bagwell, Mavroidis, and Staiger (2003), they describe arguments that lend some support to the efficacy of Mexico's proposed solution from the perspective of formal economic theory.Information Technology,International Terrorism&Counterterrorism,General Technology,Economic Theory&Research,Environmental Economics&Policies,Trade and Services,Economic Theory&Research,International Terrorism&Counterterrorism,Information Technology,World Trade Organization
