Using tools from spectral analysis, singular and regular perturbation theory, we develop a systematic method for analytically computing the approximate price of a large class of derivative‐assets. The payoff of the derivative‐assets may be path‐dependent. In addition, the process underlying the derivatives may exhibit killing (i.e., jump to default) as well as combined local/nonlocal stochastic volatility. The nonlocal component of volatility may be multiscale, in the sense that it may be driven by one fast‐varying and one slow‐varying factor. The flexibility of our modeling framework is contrasted by the simplicity of our method. We reduce the derivative pricing problem to that of solving a single eigenvalue equation. Once the eigenvalue equation is solved, the approximate price of a derivative can be calculated formulaically. To illustrate our method, we calculate the approximate price of three derivative‐assets: a vanilla option on a defaultable stock, a path‐dependent option on a nondefaultable stock, and a bond in a short‐rate model.  相似文献

An event travel career is a potentially lifelong pattern of travel to events linked with an individual’s preferred leisure activity. This paper applies the concept of an event travel career to non-elite triathletes. For these active sport tourists, ongoing pursuit of an event travel career is arguably constrained by competing priorities that intervene between everyday life and their pursuit of an event travel career. In-depth interviews were conducted with 21 triathletes identified as pursuing an event travel career. Interpretive analysis revealed seven domains of competing priorities that could work to constrain their event travel career aspirations. These domains included familial relationships, domestic responsibilities, sociability, finances, leisure, wellbeing, and work/education. The seven competing priority domains were interrelated, and cyclical in their constraining effects. Data assisted in clarifying some defining characteristics of the event travel career concept, and challenged notions of leisure participation as entirely positive and fulfilling.  相似文献

We study the effects of Chinese monetary policy shocks on China's major trading partners in East and South‐East Asia by estimating structural vector autoregressive (SVAR) models for six economies in the region. We find that a monetary expansion in Mainland China leads to an increase in real GDP (temporary) and the price level (permanent) in a number of economies in our sample, most notably in Hong Kong and the Philippines. The impact could result from intertemporal substitution present in a general equilibrium framework, which allows for positive domestic impacts of foreign monetary expansions. Our results emphasize the growing importance of China for its neighbouring economies and the significance of Chinese shocks for the design of monetary policy in Asian economies.  相似文献

The need for firms to compete in the longer run by offering superior products at competitive prices requires better integration of R&D, and technology in general, into business strategy development. A survey based on personal interviews of 40 respondents from “Fortune 500” U. S. industrial firms reveals that their shift in emphasis toward new product/process R&D is providing the impetus for placing R&D in a strategic context. However, R&D has not been fully integrated into the strategic planning process of many organizations. The results of the survey reveal that certain communication channels can be more fully utilized to meld R&D planning into business strategy. Specific suggestions to facilitate information exchange, dissemination of planning data, and integration of various R&D plans into a cohesive technology strategy are given.  相似文献

Food trucks represent a temporary use of vacant or underutilised land. They have been assumed to increase the livability, vibrancy and attractiveness of a neighbourhood. However, no previous study has investigated whether this effect is reflected in property prices within the surrounding neighbourhood. We investigate the impact of a food truck pod on the values of single-family homes nearby. Using a quasi-experimental design, transaction data from Portland, Oregon and a difference-in-difference specification of a spatial regression model, we find that food trucks actually represent a negative externality, and that proximity of a home to food trucks is penalised by homebuyers. The closer a home is to the food trucks, the lower is the sales price. Explanations for this effect include increased parking shortages and trash issues in a neighbourhood due to food truck visitors.  相似文献

In this paper we use agency theory to present a process of the dichotomization of the Israeli workforce into two structures, each representing distinct organizational cultures. The first structure is the private sector, led by the high-tech industry; a model where the principal has strong control over the activities of the agent. The second is the public sector, an opposing model in which the principal has virtually no control over the activities of the agents and as a result, the effectiveness within this sector deteriorates. We argue that such conflicting systems cannot exist side by side without affecting each other and we suggest a role for human resource management (HRM) in future developments. Within the public sector it is the responsibility of the principal, the Israeli government, to gain more control over the agent and employ professional HRM systems for this purpose.  相似文献

La economía de Tailandia ha cambiado rápidamente de la agricultura a la industria manufacturera y el sector de los servicios, pero el ordenamiento del mercado laboral y la representación de los trabajadores son mucho menos consistentes que en los países desarrollados, donde hubo una transición más lenta y gradual hace ya décadas. Los autores estudian el robustecimiento de las políticas y la legislación tailandesas en el ámbito de la seguridad y la salud en el trabajo, que obedece a las normas internacionales y a la nueva Constitución democrática. Por último, identifican los principales retos pendientes, entre ellos el cumplimiento de la ley y una medición mejor de los efectos del trabajo en la salud física y mental.  相似文献
