The paper compares free trade with autarky in an asymmetric multi‐country world under Cournot competition with constant returns to scale and linear demand. We derive respective conditions under which free trade will hurt a country's consumers, benefit its firms, induce it to export, increase its output and raise its welfare. We show that these conditions are linked in a clear order, with one implying the next. We further demonstrate that free trade can reduce world total output and total consumer surplus as well as world welfare. Along the way, we correct several oversights in the literature. 相似文献

This paper discusses an optimal investment, consumption, and life insurance purchase problem for a wage earner in a complete market with Brownian information. Specifically, we assume that the parameters governing the market model and the wage earner, including the interest rate, appreciation rate, volatility, force of mortality, premium-insurance ratio, income and discount rate, are all random processes adapted to the Brownian motion filtration. Our modeling framework is very general, which allows these random parameters to be unbounded, non-Markovian functionals of the underlying Brownian motion. Suppose that the wage earner’s preference is described by a power utility. The wage earner’s problem is then to choose an optimal investment-consumption-insurance strategy so as to maximize the expected, discounted utilities from intertemporal consumption, legacy and terminal wealth over an uncertain lifetime horizon. We use a novel approach, which combines the Hamilton–Jacobi–Bellman equation and backward stochastic differential equation (BSDE) to solve this problem. In general, we give explicit expressions for the optimal investment-consumption-insurance strategy and the value function in terms of the solutions to two BSDEs. To illustrate our results, we provide closed-form solutions to the problem with stochastic income, stochastic mortality, and stochastic appreciation rate, respectively. 相似文献

The situation in the Middle East has developed through an episodic process in which the protagonists have periodically changed the ‘game’ that they are playing by inventing new options, seeking to eliminate the options available to others, or by raising or eliminating doubts in the minds of others about their intentions. Such conflict evolution is readily captured by the framework of drama theory which goes some way to explaining the pressures motivating such actions. This paper traces the recent development of relations between the Israelis and the Palestinians through a succession of drama theoretic models. The importance of taking note of interactions at several levels is highlighted: stalemate at one level may be dislodged by actions taken in others. It is concluded that any resolution of the confrontations in the Middle East is likely to require the active involvement of the international community but may be destabilised by pressure from internal factions within the key parties. 相似文献

Using a sample of workers and managers employed by a hotel located in Southeastern People’s Republic of China, we investigated the relationship between various human resource management practices and the perceived organizational support (POS) experienced by the employees. We then investigated the effects of POS on employee satisfaction. Our data suggest that hiring practices, training, and compensation practices predict POS. These results are consistent with previous research. We also found that POS influences worker satisfaction and acts as a mediator between select HR practices and satisfaction. This study contributes to the literature by replicating Western-based findings with a Chinese sample and illustrating that the attitudes of Chinese employees can be influenced through the use of HR practices. 相似文献

We adopt the view that greater party discipline induces legislators to commit to promised policies after being elected. We then develop the hypothesis that the effect of party discipline on the stringency of environmental policy is conditional on the degree of government corruption. Our empirical work suggests that greater party discipline results in more stringent environmental policies when the level of corruption is relatively low, but in weaker policies when the level of corruption is comparatively high. 相似文献
