This paper gives a tree-based method for pricing American options in models where the stock price follows a general exponential Lévy process. A multinomial model for approximating the stock price process, which can be viewed as generalizing the binomial model of Cox, Ross, and Rubinstein (1979) for geometric Brownian motion, is developed. Under mild conditions, it is proved that the stock price process and the prices of American-type options on the stock, calculated from the multinomial model, converge to the corresponding prices under the continuous time Lévy process model. Explicit illustrations are given for the variance gamma model and the normal inverse Gaussian process when the option is an American put, but the procedure is applicable to a much wider class of derivatives including some path-dependent options. Our approach overcomes some practical difficulties that have previously been encountered when the Lévy process has infinite activity.  相似文献

This article matches establishment-level data on workplace transformation (e.g., quality circles, work teams, and just-in-time production) with measures of cumulative trauma disorders at these same establishments to explore the relationship between "flexible" workplace practices and workplace health and safety. The results reveal a positive, statistically significant, and quantitatively sizable relationship between cumulative trauma disorders and the use of quality circles and just-in-time production.  相似文献

This paper examines the comments submitted by UK companies on 20 proposed accounting standards to test the hypotheses that executives favor standards that increase, or dampen the variance of, accounting profit numbers on which their incentive remuneration is based. Test results were generally as hypothesised but only the profit variance outcomes were statistically significant. Allowing for political environment changes affected only the profit variance results. There was no evidence that the relative monetary size of bonus payments was a significant lobbying factor. No significant differences were found between the lobbying preferences of companies with or without executive incentive schemes.  相似文献

Consolidation in the banking industry has sparked concern about the survival of small banks, particularly as it relates to the availability of credit to small businesses. However, if small banks have an advantage in processing credit information, compared to large banks, they should continue to survive in a competitive environment. We evaluate risk-adjusted commercial loan yields (gross yields less net charge-offs and the risk-free rate of return) at small and large banks for the period of 1996 through 2001. Our primary finding is that, after controlling for market concentration, cost of funds, and a variety of other factors that might influence yields, smaller banks earn greater risk-adjusted yields than larger banks. This result suggests that small banks make better choices from the available small business loans and is consistent with the notion that these banks have an information advantage in evaluating credit.  相似文献

All three pillars of the British pensions system are crumbling. The basic state pension is unsustainable in its present form. Defined benefit occupational pension schemes are fast disappearing, and with them the retirement hopes of millions of workers. A further 3 million low-income earners are not saving enough for their retirement. And uncertainty about pensions choices is widespread. In each case the primary cause of the problem is governmental or regulatory failure. The paper makes eight general and four specific proposals for restoring the system.  相似文献

Regional integration: an empirical assessment of Russia   总被引:1,自引:0,他引:1  
Using a statistical model of commodity trade, we quantify the evolution of regional economic integration within Russia during 1995–1999, and explore potential determinants of this evolution. Our integration measure exhibits rich regional variation that, when aggregated to the national level, fluctuates substantially over time. In accounting for this behavior, we draw in part on theoretical models that emphasize the potential role of openness to international trade and regional disparities in income in threatening economic integration. Controlling for a host of additional regional- and national-level variables, we find a strong negative correspondence between openness to international trade and internal economic integration.  相似文献
