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

Why Democracies Cooperate More and Fight Less: The Relationship Between International Trade and Cooperation 总被引:1,自引:0,他引:1
Solomon W. Polachek 《Review of International Economics》1997,5(3):295-309
This paper provides an economics-based interpretation of the standard finding in the literature that democracies rarely fight each other. A general theory of conflict between two countries is presented and empirical analysis applies this theory to the question of why democracies rarely fight each other. The results show that the fundamental factor in causing bilateral cooperation is trade. Countries seek to protect wealth gained through international trade, therefore trading partners are less combative than nontrading nations. Democratic dyads trade more than nondemocratic dyads, and thus exhibit less conflict and more cooperation. 相似文献

In spite of decades of research into high‐performance work systems, very few studies have examined the relationship between executive learning and development and organisational performance. In an attempt to close this gap, this study explores the effects of a validated four‐dimensional executive learning and development measure on a composite measure of organisational performance. The study is based on ordinal regression analysis with empirical data elicited from 222 executives and senior leaders drawn from a wide geographic region. The theoretical link theoretical between the two variables was established by building on the Activity‐Motivation‐Outcome concept in order to encapsulate human capital, dynamic capability, resource dependency, social exchange and leader‐member‐exchange theories. The study reported an overall positive effect of executive learning and development on firm performance and has significant implications for the effective development of executive and senior management capabilities as a means of improving organisational effectiveness. 相似文献

Rural households in the semiarid Northern Ethiopian highlands are net buyers of food. Crop failure due to erratic and unpredictable rainfall occurs frequently and leads to food shortages and income shocks. The renting out of land may be one of the coping responses of households exposed to shocks. We developed a theoretical household model for poor landlord households capturing their contract choice response to downside production shocks. We tested econometrically whether contract choice may depend on poverty, capital constraints, production risk and random shocks. The multinomial logit model estimates show that poor households experiencing random shocks are more likely to choose fixed‐rent contracts as a distress response to shocks, suggesting that fixed‐rent contracts may be used to meet immediate needs, but at the expense of future incomes. We also found that fixed‐rent contracts are preferred when ex ante production risk is low, while sharecropping is more likely where production risk is high. Finally, we found an indication that the choice of a fixed‐rent contract as a coping response to shocks comes as a last resort after all other means of coping are exhausted. 相似文献
