Fixed points of the (most) refined best reply correspondence, introduced in Balkenborg et al. (2013), in the agent normal form of extensive form games with perfect recall have a remarkable property. They induce fixed points of the same correspondence in the agent normal form of every subgame. Furthermore, in a well‐defined sense, fixed points of this correspondence refine even trembling hand perfect equilibria, while, on the other hand, reasonable equilibria that are not weak perfect Bayesian equilibria are fixed points of this correspondence. 相似文献

We model the relationship between bilateral foreign direct investment (FDI) and the level of corruption in multinational firms’ (MCNs’) home and host countries. We construct and test a model of bilateral FDI between countries that differ in their levels of corruption. FDI is affected negatively both by the level of corruption in the host country and by differences in home- and host-country corruption. Our model emphasizes that MNCs develop skills for dealing with home-country corruption, and these skills become a competitive advantage in similarly corrupt host countries. We test the model using data on bilateral FDI stocks among a large number of home and host countries, using a variety of specifications and estimation strategies to provide robustness. Our results show that the effects of host-country corruption and of differences in corruption levels between home and host countries are statistically and economically significant. 相似文献

The demographic imbalance is aggravating, and by 2060 the old-age dependency ratio will double to approximately 70%. This development has consequences for the state pension system: growing contribution rates to social security coupled with lower pension levels, but at the same time a higher retirement age. The German pension scheme is mandatory for all wage and salary earners, but since 2001, no reasonable indicator for measuring the pension level exists any more. As a consequence of this, old-age pension has lost its traditional function as a replacement for earnings. The recent pension reforms have dropped the pension level sharply. Further reductions have been announced with the consequence of increasing old age poverty. Against this background it is proposed to raise the pension level so that the pensioners can maintain their standard of living. But any pension reform involves issues of distribution between and often also within generations, which cannot be addressed without explicit equity criteria. Some authors consider the past reforms as a mistake, others suggest adjustments. 相似文献

This article presents a study of a practical assignment problem found in teaching within higher education. Here, students are assigned to scientific topics for which written papers must be submitted. Often, preferences across topics exist among other side constraints that should be considered in solving the problem of interest. Characterizing attributes of real-world problems were studied for scientific departments in Economics and Business Administration at German universities by sending out 800 questionnaires, and analyzing the 203 responses.Based on earlier studies, a Variable Neighborhood Search (VNS) approach was formulated to solve the resulting assignment problem. Several neighborhood search operators were tested, and numerical results are reported for a range of problem scenarios taken from real-world cases. It was observed that VNS leads to superior results vs. single operator local search approaches. Furthermore, we were able to show that in the studied problem, the effectiveness of certain neighborhoods was, to a large extent, dependent on the structures of the underlying problem.An extension of the problem was formulated by integrating a second objective function, which simultaneously balances the workload of staff members while maximizing student utility. The VNS approach was implemented in a computer system, available free of charge, providing decision support for selected other institutions within higher education. 相似文献

The Eurosystem’s Securities Market Programme (SMP,) the purchase of government bonds of euro area countries strongly affected by the crisis, started in 2010 and ended in 2012. The SMP benefited all parties concerned – the Eurosystem, all euro area countries and the crisis countries. The positive experience with the SMP can be replicated in the private sector with the creation of an exchangetraded fund (ETF), a Smart Beta ETF - SMP Fund. Like the SMP, the SMP Fund would buy government bonds, according to the ECB capital key. As an ETF, the SMP Fund would have low costs. Profits above the German Bund benchmark would be shared: 80% to investors, 10% to the SMP Fund and 10% to advisers who recommend the purchase. The related risks would be reduced by the diversification of the SMP Fund, the financing mechanisms of the euro area, especially the European Stability Mechanism (ESM), the Outright Monetary Transactions (OMT) and the banking union. The SMP Fund could support the euro area fiscal capacity and the EU capital markets union. Past and future SMP profits create a fiscal capacity for the euro area with an initial amount of 50 billion Euro. 相似文献

This special issue focuses on empirical and theoretical papers that help us to better understand the strategy and governance of entrepreneurial networks, such as franchise chains, alliances, and cooperative networks. The following central themes are covered: (I) Which formal governance mechanisms do entrepreneurial networks use in order to reduce transaction cost/agency cost and to increase strategic value? (II) What is the role of relational governance mechanisms (such as information exchange and social ties) for the performance outcomes in franchise chains and cooperatives? (III) Which alliance strategies do entrepreneurial firms pursue to realize a competitive advantage, and what is the impact of resources and capabilities on performance outcomes of entrepreneurial firms. To address these issues, insights from organizational economics (transaction cost theory, agency theory, signaling theory), strategic management perspectives (resource-based, knowledge-based and organizational capabilities theory), entrepreneurship theory and the relational governance view are used. 相似文献

In the framework of judgment aggregation, we assume that some formulas of the agenda are singled out as premisses, and that both Independence (formula-wise aggregation) and Unanimity Preservation hold for them. Whether premiss-based aggregation thus defined is compatible with conclusion-based aggregation, as defined by Unanimity Preservation on the non-premisses, depends on how the premisses are logically connected, both among themselves and with other formulas. We state necessary and sufficient conditions under which the combination of both approaches leads to dictatorship (resp. oligarchy), either just on the premisses or on the whole agenda. Our analysis is inspired by the doctrinal paradox of legal theory and is arguably relevant to this field as well as political science and political economy. When the set of premisses coincides with the whole agenda, a limiting case of our assumptions, we obtain several existing results in judgment aggregation theory. 相似文献
