An analysis of snow options for ski resort establishments   总被引:1,自引:0,他引:1  
This study proposes a pricing method for put options on snow level for tourism establishments operating in Palandoken ski resort in the east of Turkey. In the calculation of put prices historical densities and Edgeworth adjusted densities methods together with Alaton, Djehiche, and Stillberger (2002) method have been applied. The findings show that there may be significant differences in the prices calculated by the three different methods, hence enabling both parties, i.e. buyers and sellers, with bases in the negotiation process. As the study is primarily aimed at providing a framework for pricing put options on snow levels in general, it is expected that it would be of use not only for this particular ski resort but also for various ski resorts in the world.  相似文献

Proponents of value-added agricultural enterprises (VAAE) argue for favorable government policies and funds to promote these industries as a local development strategy. Though regularly advocated at all levels of government, the beliefs regarding the benefits of VAAE to local economies merit empirical investigation. A county-level analysis of the contiguous U.S. states for a ten-year time period was used to evaluate the contribution of selected VAAE to county economic well-being. The two-stage least squares regression coupled with spatial econometric methods suggests that the support for these selected VAAE as a tool of local economic well-being, measured using income and employment growth and change in poverty rates, is not well founded.  相似文献

In this article, we derive conditions in an imperfect market setting, under which the introduction of a self‐supporting insurance guaranty fund improves the position of the policyholders. When a guaranty fund is advantageous given homogeneous firms in the market, all policyholders benefit from it to the same extent, if they have the same underlying risk preferences and are charged identical premiums. In a more realistic heterogeneous setting, the introduction of an insurance guaranty fund is in general no longer beneficial for all policyholders in the same manner. Hence, systematic wealth transfers take place between the policyholders of different insurance companies. As a possible solution, and in order to counteract this effect, we introduce a framework for utility‐based fund charges.  相似文献

This paper suggests a framework for acquisition of new manufacturing technology that links the manufacturing strategy, market requirements and manufacturing attributes using an expert system approach. This paper takes a closer took at traditional notion of manufacturing-marketing coordination and attempts to find its links with manufacturing capabilities provided by recent evolving new manufacturing technology. For this purpose we deal with different steps involved in the strategic evaluation process beginning with the choice of a suitable competitive strategy by a firm. Then the chosen competitive strategy is linked with the market requirements, system attributes and appropriate manufacturing technology choices. The proposed model is integrated by an expert system approach that includes strategic factors of both a tangible and an intangible nature and is implemented by using the VP-Expert shell.  相似文献

The structure of intra-household allocation is crucial to know whether a transfer from a rich household to a poor one translates into a transfer from a rich individual to a poor one. If rich households are more unequal than poor ones, then a progressive transfer among households reduces intra-household inequality, hence inequality among individuals. More specifically, two conditions have to be satisfied for extending Generalized Lorenz judgments from household level to individual one. The fraction of the couple's expenditures devoted to goods jointly consumed should decrease at the margin with the couple's income as well as the part of private expenditure devoted to the disadvantaged individual. This double concavity condition is non-parametrically tested on the French Household Expenditure Survey (2000). It is not rejected by the data and supports the view that power is more evenly distributed in poor households.  相似文献

In this paper, models for claim frequency and average claim size in non-life insurance are considered. Both covariates and spatial random effects are included allowing the modelling of a spatial dependency pattern. We assume a Poisson model for the number of claims, while claim size is modelled using a Gamma distribution. However, in contrast to the usual compound Poisson model, we allow for dependencies between claim size and claim frequency. A fully Bayesian approach is followed, parameters are estimated using Markov Chain Monte Carlo (MCMC). The issue of model comparison is thoroughly addressed. Besides the deviance information criterion and the predictive model choice criterion, we suggest the use of proper scoring rules based on the posterior predictive distribution for comparing models. We give an application to a comprehensive data set from a German car insurance company. The inclusion of spatial effects significantly improves the models for both claim frequency and claim size, and also leads to more accurate predictions of the total claim sizes. Further, we detect significant dependencies between the number of claims and claim size. Both spatial and number of claims effects are interpreted and quantified from an actuarial point of view.  相似文献

This paper uses a panel structural vector autoregressive (VAR) model to investigate the extent to which global financial conditions, i.e., a global risk-free interest rate and global financial risk, and country spreads contribute to macroeconomic fluctuations in emerging countries. The main findings are: (1) global financial risk shocks explain about 20% of movements both in the country spread and in the aggregate activity in emerging economies. (2) The contribution of global risk-free interest rate shocks to macroeconomic fluctuations in emerging economies is negligible. Its role, which was emphasized in the literature, is taken up by global financial risk shocks. (3) Country spread shocks explain about 15 percent of the business cycles in emerging economies. (4) Interdependence between economic activity and the country spread is a key mechanism through which global financial shocks are transmitted to emerging economies.  相似文献

Fractional management companies (FMCs) that provide on-demand air travel services experience frequent changes in aircraft availability and flight requests. We propose scheduling heuristics which are both cost-effective and persistent (i.e., close to the original schedule) to address the uncertainty. The heuristics include pro-actively enforcing idleness of aircraft in creating the original schedule, strategically repositioning aircraft to serve yet-unknown demand and dense scheduling. Computational experiments are conducted in a simulator that mimics FMCs’ daily operations. Simulation results quantify the value of each heuristic, which can be easily incorporated into existing computational methods used in FMCs for static scheduling problems.  相似文献

This article applies new insights into business strategies and high‐performance work systems (HPWSs) to examine why organizations adopt work‐life balance programs (WLBPs). Results indicate that a product leadership business strategy is positively related to the likelihood of adopting WLBPs, whereas a cost leadership business strategy is negatively related to the adoption of these programs. Moreover, our analyses establish a mediating role of HPWSs in the relationship between business strategies and the adoption of WLBPs. Our results also demonstrate that different industries vary in adoption of work‐life balance programs. This supports the institutional theory of organizational responsiveness to work‐life balance issues. We tested our hypotheses with two waves of the nationally representative Canadian Workplace and Employee Survey. Implications and specific suggestions for human resource practitioners are discussed. © 2012 Wiley Periodicals, Inc.  相似文献
