This article specifies what an optimal pollution tax should be when dealing with a vertical Cournot oligopoly. Polluting firms
sell final goods to consumers and outsource their abatement activities to an environment industry. It is assumed that both
markets are imperfectly competitive. Thus, the tax is a single instrument used to regulate three sorts of distortions, one
negative externality and two restrictions in production. Consequently, the optimal tax rate is the result of a trade-off that
depends on the firms’ market power along the vertical structure. A detailed analysis of Cournot-Nash equilibria in both markets
is also performed. In this context, the efficiency of abatement activities plays a key-role. It gives a new understanding
to the necessary conditions for the emergence of an eco-industrial sector.

Using Stock Price Information to Regulate Firms 总被引:2,自引:0,他引:2
Antoine Faure-Grimaud 《The Review of economic studies》2002,69(1):169-190
This paper examines the role of the information contained in stock prices in the regulation of privatized firms. Stock prices contain noisy but unbiased information about firm's future prospects that regulators can use to decide on some regulatory policies. The main argument developed is that the observation of stock price movements reduces the incentives of regulators to develop their own monitoring technologies and can allow them to commit to relatively light-handed regulations. This protects firm's investments in cost reduction activities and can increase ex ante welfare. 相似文献

This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution. 相似文献

ABSTRACT Antoine Hennion is a Professor of Sociology at the Centre de Sociologie de l’Innovation (Mines-Paris Tech, PSL/CNRS). He has been researching taste and cultural practices through a pragmatic lens for three decades. He has developed an original and impactful theoretical framework bridging the Actor-Network Theory to Cultural Studies. More precisely, he reconceptualized the notions of mediation and attachment. Antoine Hennion has explored various empirical settings, including music, wine, and sports. More recently, he has contributed to a large research project on migration. His books and academic articles have had an impact on Sociology, and are getting greater attention in consumer research. 相似文献

The somatic marker hypothesis: A neural theory of economic decision 总被引:14,自引:0,他引:14
Modern economic theory ignores the influence of emotions on decision-making. Emerging neuroscience evidence suggests that sound and rational decision making, in fact, depends on prior accurate emotional processing. The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decision-making and its influence by emotion. The key idea of this hypothesis is that decision-making is a process that is influenced by marker signals that arise in bioregulatory processes, including those that express themselves in emotions and feelings. This influence can occur at multiple levels of operation, some of which occur consciously, and some of which occur non-consciously. Here we review studies that confirm various predictions from the hypothesis, and propose a neural model for economic decision, in which emotions are a major factor in the interaction between environmental conditions and human decision processes, with these emotional systems providing valuable implicit or explicit knowledge for making fast and advantageous decisions. 相似文献

Collusion, Delegation and Supervision with Soft Information 总被引:16,自引:0,他引:16
Antoine Faure-Grimaud Jean-Jacques Laffont David Martimort 《The Review of economic studies》2003,70(2):253-279
This paper shows that supervision with soft information is valuable whenever supervisors and supervisees collude under asymmetric information and proceeds then to derive an Equivalence Principle between organizational forms of supervisory and productive activities. We consider an organization with an agent privately informed on his productivity and a risk averse supervisor getting signals on the agent's type. In a centralized organization, the principal can communicate and contract with both the supervisor and the agent. However, these two agents can collude against the principal. In a decentralized organization, the principal only communicates and contracts with the supervisor who in turn sub-contracts with the agent. We show that the two organizations achieve the same outcome. We discuss this equivalence and provide various comparative statics results to assess the efficiency of supervisory structures. 相似文献

This paper analyzes the allocation of two types of individuals differentiated by talent between two countries where they choose to be workers or entrepreneurs. An equilibrium with international migration exists when countries' talent endowments are sufficiently different. It is consistent with one-way or two-way migration whether individuals are entrepreneurs or workers. Although allowing migration increases domestic welfare in one country and decreases it in the other, it is always supported by majority voting in both countries. 相似文献

We consider a bisector reproduction model in which money is introduced as a pure means of exchange issued by a bank at the producers' requests. Each capitalist aims at maximizing accumulation in his own sector. Their plans are based on available quantities and expected prices. Effective prices are determined by a market mechanism. Temporary disequilibria occur in both physical and monetary terms. The settlement of the monetary balances is operated by means of a transfer of capital goods. Final allocations and effective productions are thus determined. The dynamics of the economy are those of a sequence of temporary disequilibria and let appear several possibilities (local or global stability, cycles) depending on the values of the parameters. 相似文献

A question at the center of many analyses of optimal monetary policy is, why do central banks never implement the Friedman rule? To the list of answers to this question, we add neoclassical production (specifically, the Tobin effect) as one possible explanation. To that end, we study an overlapping generations economy with capital where limited communication and stochastic relocation create an endogenous transactions role for fiat money. We assume a production function with a knowledge externality (Romer style) that nests economies with endogenous growth (AK form) and those with no long-run growth (the Diamond model). The Tobin effect is shown to be always operative. Under CRRA preferences, a mild degree of social increasing returns is sufficient (but not necessary) for some positive inflation to dominate zero inflation and for the Friedman rule to be sub-optimal, irrespective of the degree of risk aversion. 相似文献
