For any given set-valued solution concept, it is possible to consider iterative elimination of actions outside the solution set. This paper applies such a procedure to define the concept of iterated monotone potential maximizer (iterated MP-maximizer). It is shown that under some monotonicity conditions, an iterated MP-maximizer is robust to incomplete information [A. Kajii, S. Morris, The robustness of equilibria to incomplete information, Econometrica 65 (1997) 1283-1309] and absorbing and globally accessible under perfect foresight dynamics for a small friction [A. Matsui, K. Matsuyama, An approach to equilibrium selection, J. Econ. Theory 65 (1995) 415-434]. Several simple sufficient conditions under which a game has an iterated MP-maximizer are also provided. 相似文献

Optimal Insurance Against Climatic Experience 总被引:1,自引:0,他引:1
Olivier Mahul 《American journal of agricultural economics》2001,83(3):593-604
An optimal insurance contract against a climatic risk is derived in the presence of an uninsurable and dependent aggregate production risk. The optimal design depends on the stochastic dependency between both sources of uncertainty and on the producer's attitude towards risk, especially on his prudent behavior. Rational weather insurance purchasing decisions are also derived. The prudent producer responds to actuarially fair weather insurance by increasing his exposure towards risk. 相似文献

Estimating Value Creation from Revealed Preferences: Application to Value‐based Strategies 下载免费PDF全文
Research summary : We develop and apply a new set of empirical tools consistent with the tenets of value‐based business strategies, leveraging the principle that “no good deal comes undone” and the methods of revealed preferences, to empirically estimate drivers of value creation. We demonstrate how to use these tools in an analysis of value creation in buyer–supplier relationships in the UK corporate legal market. We show that our approach can uncover evidence of subtle mechanisms that traditional methods cannot easily distinguish from each other. Furthermore, we show how the estimates can be used as parameters of biform games for out‐of‐sample analyses of strategic decisions. With readily available data on relationships between firms, this approach can be applied to many other contexts of interest to strategy researchers. Managerial summary : Managers need to understand the drivers of value creation for customers in order to make competitive positioning decisions and understand when they can capture value under competition. However, estimates of the relative importance of each driver are typically difficult to obtain. In this article, we help remedy this problem by demonstrating a novel method that obtains estimates of the contribution of various drivers of value creation from commonly available data of buyer–supplier relationships. These estimates can then be used to inform the strategy‐making process. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

This article reviews the literature of commercial diplomacy during the period 1960–2014 from a management angle and is organized around four major themes: (1) government’s export/trade promotion function; (2) institutional/organizational arrangements; (3) managerial roles and activities; and (4) interaction between commercial diplomats and businesses. A complementary quantitative analysis tracing current research trends reveals the emergence of relevant publications at the end of the 1970s and a real increase after 2000. It also confirms the relative scarcity of commercial diplomacy literature focusing on the business and management dimension. Gaps in current literature are identified, and suggestions for further research are presented. 相似文献

In a panel of European countries, we analyse paper products, sawnwood and wood panels consumption data. With this object, we use a classical demand model where national consumption depends on real GDP and real prices. In contrast to previous panel estimations in the literature, we highlight non-stationarity time series which can lead to spurious regressions. We explicitly take into account the issue by using recent panel cointegration techniques. Cointegration is present for printing paper and fibreboard, though less clear cut for other products. Then we estimate demand elasticities and find that GDP elasticities are significantly lower than estimates from the literature. Finally, we simulate the implications of modified demand elasticities by using a partial equilibrium model of the forest sector. For most products, changes in elasticities would lead to lower projected demand and lower prices over a 20-year time horizon. Lower demand for solid wood and wood fibre would lead to less tensions with fuel wood- and wood-based chemical markets. In a context of rising interest for renewable bio-based products, updated long-term demand models contribute to the analysis of the forest sector’s sustainability. 相似文献

The objective of this paper is to investigate the rigorousness and reliability of sustainability rating agencies' evaluation of corporate sustainability risks. Using grounded theory, this study conducts a qualitative analysis of 32 semi‐structured interviews with practitioners involved in this activity and shows the trade‐offs and rational myths underlying this evaluation process. The image of rationality and rigorousness projected by sustainability risk measurements is mostly intended to address the increasing institutional pressures for reliable and comparable information, particularly from institutional investors and socially responsible investment decision makers. Nevertheless, risk analysts face serious challenges due to the lack of reliable information, the unpredictability of sustainability risks, the methodological issues related to the measurement process, and the complexity and context‐dependency of risk assessment. These challenges call into question the official and optimistic rhetoric of rating agencies. This study contributes to the literature on sustainability risks and rational myths in organizations. Managerial implications and avenues for future research are also discussed. 相似文献

We investigate whether entering an official hotel classification system is as lucrative as suggested in the tourism management literature. Indeed, in countries in which the official hotel classification system is voluntary, a substantial fraction of hotels choose not to enter the system, and are outsiders. Considering that being classified (being insider) as a predictor of the rate structure may raise an endogeneity issue, we apply the recursive semi-ordered probit model to control for endogeneity and appropriately assess the effect of being classified on price rates. Using a sample of 357 hotels of Corsica, we show that, in contrast to previous research, classification does not provide any rate premium. We also fully derive conditional probabilities and partial effects on differences in conditional probabilities within the recursive semi-ordered probit model. 相似文献

Proper evaluation of the impact of agricultural research requires data on how much has been spent to achieve its desired effects on productivity, efficiency and environmental quality. However, official statistics on aggregate volumes of research expenditure, at both European and national levels, are intermittently available and most data collected for private research are not fully compatible with data for public research. This study in 20 European countries in 2014 defines the different concepts at international level, and assesses coverage across countries, using secondary data and key informant interviews. Coverage is unequal by country and type of measure, the lowest coverage being for agriculture as a socioeconomic objective. We depict recent trends in public agricultural research, which differ by country. We then formulate three policy options and recommendations for their implementation to improve the monitoring of agricultural research investment in Europe: 1) make compulsory in the EU statistical system the collection of statistics on agricultural research expenditure using the same metrics for all sectors of performance; 2) develop a specific survey in the Commission to obtain data directly from research organisations; 3) prepare annual reviews of agricultural research expenditures at Member State level, including both quantitative and qualitative information on agricultural research activities. 相似文献

This article analyzes the contribution of certifiable environmental management standards—such as ISO 14001 and the Eco‐Management and Audit Scheme (EMAS)—to corporate environmental performance. Based on a content analysis of 414 third‐party‐verified environmental statements from EMAS‐registered Spanish organizations, which included information for around 6,700 detailed indicators, a weak improvement in environmental performance was found. Less than half of the analyzed indicators—namely, 48.27%—revealed a net improvement. Similarly, analysis of the justifications of the registered companies for the lack of improvement points to a rather symbolical adoption of the certification, intended to do only the bare minimum. These findings call into question the prevailing opinion about the positive impact of voluntary certifiable environmental management standards on environmental greening. Implications for managers and public policy makers, as well as for other stakeholders, are discussed. 相似文献
