Refining a discrete model of Cheuk and Vorst, we obtain a closed formula for the price of a European lookback option at any time between emission and maturity. We derive an asymptotic expansion of the price as the number of periods tends to infinity, thereby solving a problem posed by Lin and Palmer. We prove, in particular, that the price in the discrete model tends to the price in the continuous Black–Scholes model. Our results are based on an asymptotic expansion of the binomial cumulative distribution function that improves several recent results in the literature.  相似文献

The controversy around fixed-term contracts centres around the conflict between the employer’s need for flexibility and the employee’s need for security. The authors propose flexible contributions for employers to the public unemployment insurance system to balance both interests. The employers’ contributions for their temporary staff would increase while the contributions for their permanent staff would in turn decrease slightly. The authors calculate four versions. With regards to the total sum of contributions, the first version holds the contributions received constant while the second version leads to a reduction. They then repeat these two calculations for fixed-term contracts without substantive grounds. The flexibility premium takes into account the higher unemployment risk of employees with fixed-term contracts and establishes monetary incentives for employers to hire employees with permanent contracts.  相似文献

Since World War II, the modernization model has been the mainstream paradigm for economic development. Modernization assumes that foreign capital is a necessary catalyst for transforming societies from traditional to modem. Challenges to the modernization paradigm culminated in dependency theory. Dependency theorists point to detrimental effects of foreign capital and domination (e.g., income inequality, authoritarianism, and inappropriate consumption). Despite the charge by many scholars that this debate has subsided, basic but important questions remain to be answered. This paper assesses the role of U.S. direct investment (USDI) on the major economies of Latin America over time (1950–1998). Using Vector Autoregression, we look at the long‐term political relationships between USDI, economic development, and the degree of authoritarianism in the host country's government. We treat these variables as endogenous as both dependency and modernization hypothesize relationships among them. We find that there are only weak long‐term relationships between polity, development, and USDI. These results fully support neither the modernization nor the dependency model.  相似文献

This paper presents a critical discussion of the internationally prevailing understanding of the concept 'sustainable tourism'. It is argued that the current focus on stationary activities and local, intensive environmental issues is too limited both in relation to the concept of tourism and the concept of sustainable development. There is no tourism without travel. And, as shown in a Norwegian research study, tourist travel is a major source of serious environmental problems. The paper emphasises that sustainable tourism should be linked to a concept of sustainable mobility. However, this mobility would imply not only a change in the means of transport but also a reduced level of mobility in the rich part of the world. As this would entail new forms of tourism, other than those solely based on auto- and aeromobility, it represents a major challenge for the future development of tourism.  相似文献

We investigate how perceived parents’ performance in entrepreneurship (PPE) affects the entrepreneurial career intentions of offspring. We argue that while perceived PPE enhances offspring’s perceived entrepreneurial desirability and feasibility because of exposure mechanisms, it inhibits the translation of both desirability and feasibility perceptions into entrepreneurial career intentions due to upward social comparison mechanisms. Thus, perceived PPE acts as a double-edged sword for the intergenerational transmission of entrepreneurship. Our predictions are tested and confirmed on a sample of 21,895 individuals from 33 countries. This study advances the literature on intergenerational transmission of entrepreneurship by providing a foundation for understanding the social psychological conditions necessary for such transmission to occur.  相似文献

Finding an efficient method for sampling micro- and small-enterprises (MSEs) for research and statistical reporting purposes is a challenge in developing countries, where registries of MSEs are often nonexistent or outdated. This lack of a sampling frame creates an obstacle in finding a representative sample of MSEs. This study uses computer simulations to draw samples from a census of businesses and non-businesses in the Tshwane Municipality of South Africa, using three different sampling methods: the traditional probability sampling method, the compact segment sampling method, and the World Health Organization's Expanded Programme on Immunization (EPI) sampling method. Three mechanisms by which the methods could differ are tested, the proximity selection of respondents, the at-home selection of respondents, and the use of inaccurate probability weights. The results highlight the importance of revisits and accurate probability weights, but the lesser effect of proximity selection on the samples' statistical properties.  相似文献

The Asset Approach to Pricing Urban Land: Empirical Evidence   总被引:1,自引:0,他引:1  
Many papers have attempted to explain Intelmetropolitan variations in the price of housing using multi-equation models of the metropolitan housing market. This paper uses a long-run equilibrium urban asset model to explain such variations. The model builds upon previous models that introduce uncertainty into the dynamic urban model of land conversion. The empirical results strongly support the asset approach to valuing land in urban areas.  相似文献

Recent empirical research using real estate data has supported the weak and semi-strong forms of the efficient markets hypothesis. Previous studies have not included an estimate of expected appreciation into the tests of market efficiency, thus raising a question about the reliability of the results. We first use a market model to test for market efficiency with results similar to those reported by others. We next use a dynamic multiple indicator, multiple cause (DYMIMIC) model, which extracts a vector of expected appreciation from the price data, to test market efficiency. This approach produces superior results and a stronger conclusion about the efficiency of housing markets. The results indicate limited adjustment delays which can be explained by the existence of high transactions and search costs.  相似文献
