This article analyzes the role and place of the pension system in the structure of the Russian economy; the directions of its impact on major macroeconomic indicators are estimated. On the basis of a calculation system, the key requirements for the pension system in the long term are formulated.  相似文献

This paper uses primary data to analyze the institutions and informal markets that govern groundwater allocation in a sugarcane-cultivating village in North India. We find that, in contrast to earlier literature, the observed water trades result in efficient water allocation across farms. We interpret this and other stylized facts in terms of a social contract using a simple bargaining model with limited inter-player transfers. Poor functioning of the power sector leads to reduced pumping and a water supply constraint. Simulations show that power supply reform can significantly increase farm yields, and be financed out of increased farm profits.  相似文献

In the 1970s, automotive industries in developing economies were rebuked for their failure to set in motion the technological learning and industrial externalities that justified state promotion. However, in the 1990s, a number of Asian automotive industries throve with the rapid growth of their host economies. This paper assesses the current state and prospects of automotive industries in selected Asian countries with state-sponsored development programs—South Korea, Taiwan, China and India—and the ASEAN economies—Thailand, Indonesia, Malaysia, the Philippines and Vietnam. To date, Korea is the only developing economy in Asia with an indigenous auto-manufacturing base capable of competing in the international market. Given developments in the world industry, the catch-up task for other countries in the region will be more difficult.  相似文献

A Note on the Probability of Having a Strong Condorcet Winner   总被引:1,自引:0,他引:1  
In an election, a strong Condorcet winner is a candidate who is top-ranked by more than 50% of the voters. The purpose of this note is to provide some algebraic representations for the probability of having a strong Condorcet winner in three-candidate elections. Three alternative procedures for generating voting situations are considered: the Impartial Culture condition, the Impartial Anonymous Culture condition and the Maximal Culture condition. It turns out that the conclusions we obtain strongly depend on the way for generating voting situations.  相似文献

Migration dynamics and local biodiversity are interrelated in a way that is likely to affect patterns of regional specialisation. We assess this relationship with a New Economic Geography model that has been extended with biodiversity. Biodiversity is heterogeneous, and responds to habitat availability. The results indicate that a symmetric pattern of regional specialisation is more likely, and that additional equilibria may emerge as the marginal utility of biodiversity increases. In the policy analysis we focus on the case where the overall social optimum is symmetric and show that it can be supported as a non-cooperative Nash equilibrium. However, multiple Nash equilibria may exist.  相似文献

This paper considers the stability of tacit collusion in price setting duopolies with repeated interaction. The minimum discount factor above which tacit collusion can be sustained in a subgame perfect equilibrium is called the critical discount factor δ*. In addition, δ* is often used as an intuitive measure for the stability of a tacit cartel, assuming that a collusive equilibrium is more difficult to sustain when δ* increases. However, according to standard theory the distance δ − δ* between the actual and the critical discount factor does not matter for stability as long as δ > δ*. This paper contributes experimental evidence that supports the intuitive idea that a larger critical discount factor makes collusion a less likely outcome.   相似文献

In recent months, the list of large diversified companies that have decided they would be worth more as several smaller, focused companies has grown sharply. In many of these cases, it has been outside pressure from activist investors that has motivated these actions by management—and with some pretty favorable results. But what is driving these strategic actions and what is most important in determining whether breakups create value? To answer this fundamental questions, it is critical to decide whether large, diversified companies have a value recognition problem or a value creation problem. In this article, the authors present and try to integrate the findings of two separate but related research studies on business diversity and size with the aim of identifying their implications for corporate strategy and helping company executives create more value for their investors. The specific reasons for underperformance by large diverse companies vary greatly, but there are a number of potential problems discussed in this article, including organizational “distance,” capital allocation, human capital allocation, cross subsidies, and ineffective governance. Instead of waiting for activist investors to demand a breakup, executives of large diverse companies should be proactive in addressing the potential weaknesses of their organizations. Private equity firms understand how to make diversification work and many of today's executives could learn some valuable lessons from these firms. Large diverse businesses should embrace “Internal Capitalism,” a corporate culture and set of practices that emphasizes the importance of strategic decision‐making that is linked through continuous performance assessment to the corporate goals of boosting efficiency and sustainable growth.  相似文献

New academic accountants tend to believe that there is a singular academic labor market that will receive them as they approach the completion of their doctoral programs. In such a world, the caliber of their ideas would be judged according to their ability to make a contribution to the knowledge of discipline. However, past research suggests that a prestige structure exists for doctoral programs such that a candidate’s ability to be placed at a school is a function of his/her doctoral programs position in that hierarchy. In this world, limits exist upon possible placement for most candidates such that the caliber of their work will not be a determinative factor in their placement. Various divisions of the doctoral schools in accounting show that movement to higher groups is difficult for all groups. The higher-tier schools are more able to place their graduates in the same tier. Falls to lower tiers are especially likely for the graduates of the lower prestige groups of doctoral schools. This paper seeks to help participants in the labor market, doctoral candidates and those that hire them, obtain a more informed appreciation for their realistic prospects. In this way, an achievable expectation should lead to more efficient placement behavior.  相似文献
