A detailed longitudinal dataset is assembled containing annual performance and biographical data for every player over the entire history of professional major league baseball. The data are then aggregated to the team level for the period 1920–2009 in order to test whether teams built on a more even distribution of observed talent perform better than those teams with a mixture of highly able and less able players. The dependent variable used in the regressions is the percentage of games a team wins each season. We find that conditioning on average player ability, dispersion of both batting and pitching talent displays an optimal degree of inequality, in that teams with too high or too low a spread in player ability perform worse than teams with a more balanced distribution of offensive and defensive talent. These findings have potentially important applications both inside and outside the sporting world.  相似文献

Firms as source of variety in innovation: influence of size and sector   总被引:3,自引:0,他引:3  
This article seeks to fulfill two main objectives. It firstly seeks to identify and quantify characteristics and behaviors of firms that are associated with what, in the evolutionary stream, is known as variety in innovation. A factor analysis is applied with a view to establishing, from a sizeable group of variables related to business innovation, the main factors or sources of variety in innovation in firms. The second goal is to estimate the influence of two variables that have been traditionally related to innovative firm activity on each of these sources: size and sector. The results of the analysis show seven important sources of variability in innovation for firms and that the influence of size and sector of activity on innovation occurs, at different levels of intensity, through these sources. The empirical analysis is based on the responses given for managers of a representative sample of enterprises in a personal interview.  相似文献

In this article, we formulate linear Gaussian state space models for the estimation of the exchange rate pass-through of the Brazilian Real against the US Dollar, using monthly data from August 1999 to August 2008. The state space/Kalman filtering framework allows the investigation of some empirical aspects previously suggested in the literature, such as time-varying coefficients and null/full pass-through hypotheses. We also test whether some theoretical ‘determinants’ of the pass-through are statistically significant in the period considered. The principal findings are as follows: (1) the data offer strong support to a time-varying pass-through; and (2) the variance of the exchange rate pass-through, the monetary policy and the trade flow have shown to be relevant determinants of the exchange rate pass-through.  相似文献

Female tourists and beach boys: Romance or Sex Tourism?   总被引:2,自引:0,他引:2  
Previous studies of female tourists and beach boys in the Caribbean have defined these relationships as involving either sex or romance tourism. The objective of this study was to determine which of these definitions was more applicable to relationships in the Dominican Republic. Male and female tourists as well as beach boys and female sex workers were interviewed. Romance and sex tourism were conceptualized as the two ends of a continuum of motivations rather than as distinct categories. Although there was some gender overlap in the continuum of romance/sex motivations, more of the female tourists were located toward the romance end and more of the male tourists toward the sex end of the continuum.  相似文献

The tourism sector has evolved in recent times, with a transformation in tourists’ preferences and behaviour. They are increasingly abandoning standard tours in favour of more personalised options. New technologies offer easy access to a large amount of tourism information. However, this also means it is difficult for a decision-maker to assess all the possible alternatives for designing a customised trip. Making such decisions may well require the resolution of conflicting objectives. Therefore, in this paper we develop a tool that provides each tourist with the itinerary best suited to their needs. This itinerary can include the desired different activities on an established schedule, bearing in mind the tourist’s wishes and needs, along with the characteristics of the area. This is done by using a mathematical model and interactive multi-criteria techniques. Finally, we will carry out a practical application in the Autonomous Region of Andalusia.  相似文献

The purpose of this article is to offer guidelines to deal with hard choices, specifically in situations where some compromise among opposing values is inescapable. The guidelines are intended to help ethicists and practitioners to delineate different alternatives and to dismiss some of them as morally unacceptable. This article explores the view that compromises arise from negotiations but from ethical predicaments as well. For this reason, I distinguish between strategic and moral compromises. Both managers and employees are individual moral agents who have to confront the possibility of unpalatable and even disgusting compromises, so that they are forced to put their integrity into risk in certain compromise situations. However, I shall argue for the possibility of palatable moral compromises. The guidelines to cope with those situations and to identify the unpalatable compromises are based on J. S. Mill's moral philosophy. Mill suggested that half‐measures passed in Parliament must have certain key elements to be morally acceptable. I make use of this doctrine to put forward compromise guidelines in the form of a set of hallmarks, internal and external elements of palatable compromises. Two minicases are used to test the guidelines and to emphasize the importance of compromises for ethical decision making and commitment to company.  相似文献

Agency Problems and Dividend Policies around the World   总被引:62,自引:0,他引:62  
This paper outlines and tests two agency models of dividends. According to the "outcome model," dividends are paid because minority shareholders pressure corporate insiders to disgorge cash. According to the "substitute model," insiders interested in issuing equity in the future pay dividends to establish a reputation for decent treatment of minority shareholders. The first model predicts that stronger minority shareholder rights should be associated with higher dividend payouts; the second model predicts the opposite. Tests on a cross section of 4,000 companies from 33 countries with different levels of minority shareholder rights support the outcome agency model of dividends.  相似文献

This paper analyzes how a country's degree of economic development affects the impact of banking crises on international trade. To this end, we estimate a gravity model of trade using a sample of 139 countries over the period 1975–2012. Our results show that middle income countries are generally the most negatively affected. In contrast, financial turmoil appears to have less impact on bilateral trade flows among high income countries and, more specially, among low income nations. The level of financial development, contract enforcement, as well as the extent of the use of banking credit within international trade all help to explain our findings.  相似文献
