ABSTRACTThis article shows the methodology and the main figures of the local and regional economic impact generated by cruise activity. This article is pioneering in combining different issues: estimating the impact of the cruise port activity, presenting these impacts disaggregated at a sectoral level, using a rigorous methodology and carrying out extensive fieldwork. It is demonstrated that all sectors, not just traditional tourism-related sectors, benefit from cruise tourism. In order to test and apply our methodology we focus the analysis on the Port of Barcelona, which has become the leading cruise port in the Mediterranean area. 相似文献

Secret information acquisition in Cournot markets 总被引:2,自引:0,他引:2
Summary. Two-stage game models of information acquisition in stochastic oligopolies require the assumption that firms observe the
precision of information chosen by their competitors before determining quantities. This paper analyzes secret information
acquisition as a one-stage game. Relative to the two-stage game firms are shown to acquire less information. Policy implications
based on the two-stage game yield, therefore, too high taxes or too low subsidies for research activities. For the case of
heterogeneous duopoly we briefly discuss comparative statics results.

In the present study I identify an inherent characteristic of health care markets that may lead to excessive investment by hospitals even when compensated according to a prospective reimbursement rule. It is demonstrated that the stochastic nature of the demand for medical services combined with the lumpiness of investment decisions may give rise to excessive investment when multiple hospitals select independently their levels of capacities. The source for the excessive incentives to invest is the difficulty of one hospital to internalize properly the externality generated by its investment decisions. Such an externality arises because when one hospital expands its capacity, it is more likely to be able to serve not only patients residing in its region but patients residing in neighboring regions as well. 相似文献

This paper surveys recent work in contract theory that relates to the allocation of tasks among agents within an organization as well as to the effect of product market competition upon optimal contracting and agency costs. 相似文献

Using a quantity conjectural variation model, this paper examines whether an ad valorem tariff and a specific tariff are equivalent under duopoly. We show that if the average per‐unit import tax is the same for the two tariffs, domestic output will be smaller while foreign output will be larger under an ad valorem tariff. We further show that for any value of a specific tariff, there is a Pareto‐superior ad valorem tariff for all values of conjectural variation except in the case of perfect competition where the two tariffs are equivalent. 相似文献

We propose a novel approach to active risk management based on the recent Basel II regulations to obtain optimal portfolios with minimum capital requirements. In order to avoid regulatory penalties due to an excessive number of Value-at-Risk (VaR) violations, capital requirements are minimized subject to a given number of violations over the previous trading year. Capital requirements are based on the recent Basel II amendments to account for the ‘stressed’ VaR, that is, the downside risk of the portfolio under extreme adverse market conditions. An empirical application for two portfolios involving different types of assets and alternative stress scenarios demonstrates that the proposed approach delivers an improved balance between capital requirement levels and the number of VaR exceedances. Furthermore, the risk-adjusted performance of the proposed approach is superior to that of minimum-VaR and minimum-stressed VaR portfolios. 相似文献

This paper investigates impact factor as a metric for ranking the quality of journal outlets for operations management (OM) research. We review all prior studies that assessed journal outlets for OM research and compare all previous OM journal quality rankings to rankings based on impact factors. We find that rankings based on impact factors that use data from different time periods are highly correlated and provide similar rankings of journals using either two-year or five-year assessment periods, either with or without self-citations. However, some individual journals have large rank changes using different impact factor specifications. We also find that OM journal rankings based on impact factors are only moderately correlated with journal quality rankings previously determined using other methods, and the agreement among these other methods in ranking the quality of OM journals is relatively modest. Thus, impact factor rankings alone are not a replacement for the assessment methods used in previous studies, but rather they evaluate OM journals from another perspective. 相似文献

The reduced form of the local level model with conditionally heteroscedastic GARCH(1,1) noises is analyzed. We show that the IMA-GARCH model is a good alternative but its conditional heteroscedasticity is weaker than this of the unobserved disturbances. 相似文献
