In this paper we study the impact of the regulations on Maximum Residue Levels (MRLs) of pesticides on the trade of apples and pears and related processed products with the aim of understanding how their similarity (or dissimilarity) affect trade. Most studies investigate the impact of sanitary regulations introducing directly in the analysis the MRL put in force in the importing country. They introduce in the analysis the level of the regulation in the importing country without taking into account the rule in force in the exporting country. Rather than focusing on a particular pesticide we take into account the entire list of substances set out by the various regulations. We then build a similarity index and introduce it into a gravity equation to assess the impact of the differences in MRL of pesticides on trade. Results suggest that the differences between regulations matter and may, in some case, hinder trade. 相似文献

Summary. This paper investigates Nash equilibrium under the possibility that preferences may be incomplete. I characterize the Nash-equilibrium-set of such a game as the union of the Nash-equilibrium-sets of certain derived games with complete preferences. These games with complete preferences can be derived from the original game by a simple linear procedure, provided that preferences admit a concave vector-representation. These theorems extend some results on finite games by Shapley and Aumann. The applicability of the theoretical results is illustrated with examples from oligopolistic theory, where firms are modelled to aim at maximizing both profits and sales (and thus have multiple objectives). Mixed strategy and trembling hand perfect equilibria are also discussed.Received: 22 September 2003, Revised: 24 June 2004, JEL Classification Numbers:

John Nash's work laid the foundations for evolutionary game theory as well as the theory of games with rational agents. The Nash bargaining solution emerges as a natural solution concept in both of these settings. 相似文献

We study the impact of the global financial crisis on the equilibrium exchange rate of the US dollar. We first simulate the impact of the crisis on the US net foreign asset position. Then, we calculate the equilibrium value of the dollar according both to a BEER and to a FEER approach. We find the case for a strong, although temporary, depreciation of the dollar even more acute than before the crisis. This suggests that the strength of the dollar in late 2008 and early 2009 may be short-lived. 相似文献

The aim of this paper is to investigate the impact of managers’ participation in costing system design on their perceived contributions to process improvement. Drawing on the literature on business process management, participative decision-making and self-determination theory, we propose that participation in costing system design fosters managers’ perceived contributions to process improvement through their autonomous motivation for cost management and their perceived usefulness of cost information. Questionnaire data obtained from 170 Belgian managers were used to test the proposed model. The results suggest that participation in costing system design increases managers’ autonomous motivation for cost management and enhances their perceived usefulness of cost information. Managers’ perceived usefulness of cost information is, in turn, positively associated with their perceived contributions to process improvement. The effect of managers’ autonomous motivation for cost management on their perceived contributions to process improvement is, however, not significant. Taken together, our findings imply that contributions to process improvement mainly emerge through informational mechanisms rather than motivational mechanisms triggered by the participation process. 相似文献

When an agent invests in new industrial activities, he has a limited initial knowledge of his project's returns. Acquiring information allows him both to reduce the uncertainty on the dangerousness of this project and to limit potential damages that it might cause on people's health and on the environment. In this paper, we study whether there exist situations in which the agent does not acquire information. We find that an agent with time-consistent preferences, as well as an agent with hyperbolic ones, will acquire information unless its cost exceeds the direct benefit they could get with this information. Nevertheless, a hyperbolic agent may remain strategically ignorant and, when he does acquire information, he will acquire less information than a time-consistent type. Moreover, a hyperbolic-discounting type who behaves as a time-consistent agent in the future is more inclined to stay ignorant. We then emphasize that this strategic ignorance depends on the degree of precision of the information. Finally, we analyse the role that existing liability rules could play as an incentive to acquire information under uncertainty and with regard to the form of the agent's preferences. 相似文献

Co-creation in public service delivery requires partnerships between citizens and civil servants. The authors argue that whether or not these partnerships will be successful depends on state and governance traditions (for example a tradition of authority sharing or consultation). These traditions determine the extent to which co-creation can become institutionalized in a country’s governance framework. 相似文献

We show in this paper that for the class of two-player games with compact real intervals as strategy spaces and continuous and strictly quasi-concave payoff functions there exists a monotone relation between the size of strategy spaces and the number of Nash equilibria. These sufficient conditions for our theorem to hold are shown to be tight. 相似文献

Advertisers are increasingly monitoring people's online behavior and using the information collected to show people individually targeted advertisements. This phenomenon is called online behavioral advertising (OBA). Although advertisers can benefit from OBA, the practice also raises concerns about privacy. Therefore, OBA has received much attention from advertisers, consumers, policymakers, and scholars. Despite this attention, there is neither a strong definition of OBA nor a clear accumulation of empirical findings. This article defines OBA and provides an overview of the empirical findings by developing a framework that identifies and integrates all factors that can explain consumer responses toward OBA. The framework suggests that the outcomes of OBA are dependent on advertiser-controlled factors (e.g., the level of personalization) and consumer-controlled factors (e.g., knowledge and perceptions about OBA and individual characteristics). The article also overviews the theoretical positioning of OBA by placing the theories that are used to explain consumers’ responses to OBA in our framework. Finally, we develop a research agenda and discuss implications for policymakers and advertisers. 相似文献
