Abstract In this study we examined the effect of specialization on behavioral choice among Wisconsin goose hunters, who were able to choose a relatively easy hunt at the Horicon Marsh or a more complex hunt in the exterior zones. Past research has shown that more specialized recreationists have differing motives, attitudes, satisfaction levels, crowding perceptions, environmental preferences, and management preferences. Our goal in this study was to extend this research to behavioral choices and to learn more about the dimensions of specialization in goose hunting. Specialization did not predict behavioral choice among the sample. Specialization, as measured by past experience, commitment, media involvement, club membership, and preferred hunting style, did not differ significantly when comparing Horicon goose hunters and exterior zone hunters. Novice hunters hunted alongside experienced hunters, and behavioral choice appeared to be more a function of structural constraint than attitu‐dinal preference. Specialization did explain differences in hunter judgments of quality, correlating negatively with shooting and bagging and positively with social and natural components of a quality experience. These findings indicate that although the specialization framework can effectively predict attitudinal differences among participants in a given activity, it is less efficient at predicting behavioral choice. Consequently, specialization researchers need to be cautious about inferring levels of specialization from observations of locational choice. 相似文献

We study the difference in the volatility dynamics of CBOT corn, soybeans, and oats futures prices across different delivery horizons via a smoothed Bayesian estimator. We find that futures price volatilities in these markets are affected by inventories, time to delivery, and the crop progress period and that there are important differences in the effects across delivery horizons. We also find that price volatility is higher before the harvest starts in most cases compared to the volatility during the planting period. These results have implications for hedging, options pricing, and the setting of margin requirements. © 2010 Wiley Periodicals, Inc. Jrl Fut Mark 30:846–873, 2010 相似文献

Although the resource‐based view of the firm has been written about extensively, the process by which firm assets are accumulated has not been explored in detail. That is, we know little about the micro‐level mechanisms by which assets are built, nor do we have sufficient empirical evidence why some assets are more difficult to imitate, trade, or substitute. In this exploratory paper, we attempt to provide a better understanding of asset accumulation via an empirical research program in pharmaceutical drug discovery. Using a combination of field research, discovery data from nine pharmaceutical firms, and data on 218 alliances involving new technologies for experimentation and testing, three causes affecting asset accumulation are identified and described. First, the difficulty of imitating a particular asset is affected by interdependencies with other assets. Second, trading of assets can be impeded by structural inertia in the core of a firm that is adopting the technology asset. And third, fully specifying all factors affecting imitation and trading ex ante is very difficult, if not nearly impossible, under conditions of rapid technological change. We propose that the complex interactions of these causes can give rise to imperfections in factor markets. Finally, implications for further research are discussed as well.

This article reviews some recently developed approximation schemes for financial markets with continuous trading. Two methods for approximating continuous-time stochastic securities market models whose exogenously given prices have continuous sample paths are described and compared One method approximates both the paths and the information structure; the other is an approximation in distribution with a Markovian structure. In both cases, the approximating models have a finite state space, discrete time, and possess the same “structural” properties (e.g., “no arbitrage” and “completeness”) as the continuous model. the latter characteristic is an important criterion for judging the merits of the approximations. Taking advantage of the “structure-preserving” characteristic, one can formulate a convergence theory for frictionless markets with continuous trading. the theory provides convergence results for objects such as contingent claim prices, replicating portfolio strategies (hedging policies), optimal consumption policies, and cumulative financial gains (i.e., stochastic integrals), which are constructed along the approximation. the convergence theory enables one to combine the intuitive appeal of discrete models and the analytic tractability of continuous models to provide new insight into the theory of modern financial markets. We survey the current state of such a convergence theory and illustrate the results with some examples of well-known continuous securities market models. 相似文献

Jamaica is no stranger to compulsory arbitration. Its Public Utility Undertakings and Public Services Arbitration Law (popularly known as the Essential Services Law) has been on the statute book since 1952, providing for compulsory arbitration in essential industries. During the period under review in this paper (1952–69) some 79 cases were heard. Additionally, a number of cases involved court litigation and/or illegal direct action by groups of employees or employers. The Jamaican experience has been full. This paper will seek to present and analyse what has happened in the field of compulsory arbitration in Jamaica and draw appropriate conclusions as to the relevance of the findings for other societies. 相似文献

Economists find it difficult to reach agreement about the effects on economic growth of depreciation of the money value. One reason is that they define certain terms in different ways, another one is that many other factors as well as inflation have an impact on economic growth. They may intensify or compensate for positive and negative relations between inflation and economic growth. 相似文献

—Governmental programs proposing rental supplements for low-income families assume that social and economic conditions of these families may be improved by such subsidy. However, this assumption has not been adequately tested by social science research. Data presented here were gathered at an urban renewal relocation housing project in Lubbock, Texas, and suggest that when families who, before urban renewal, were self-sufficient in slum housing are forced into welfare situations because of rent subsidy programs, dissatisfaction with relocation facilities results. The data also indicate that dissatisfaction is correlated positively with the number of persons in the household, the age of residents, and socioeconomic status. 相似文献

Organizations are increasingly relying on self-directed work teams (SDWTs) to accomplish organizational tasks. The introduction of SDWTs into the workplace poses a number of managerial challenges. This paper will focus on one such challenge, the continuing need to comply with labor and equal employment regulations. We discuss several factors that potentially affect the legal compliance process. These include: (1) the impact of an increasingly diverse workforce on individual behavior and team processes, and (2) the role of procedural justice perceptions in effective HR compliance management. We conclude with some practical solutions to the challenge of managing compliance in SDWT settings. 相似文献
