Profitability of cow-calf production is determined largely by market prices, calf weaning weights, and cow productive life. While producers individually have no effect on prices, weaning weights and productive life have genetic influences and hence can be altered by selection programs implemented by producers. We investigate the impact of a mutation in the leptin gene (exon 2; single nucleotide polymorphism [SNP] 305) on cow-calf profitability. Prior research shows that this mutation has effects on performance and traits of fed cattle and milk production in dairy cows. Using data from a teaching-research herd, we find that it is also associated with calf weaning weights and cow productive life. A bio-economic stochastic simulation demonstrates that the mutation has statistically positive impacts on profits, suggesting that producers can profitably make use of this information. 相似文献

Integrating theories and findings from various disciplines, we develop a decision utility model to explain how anticipated discrete emotions mediate investment decisions. We illustrate the model with the anticipated discrete emotions of a hypothetical Ponzi scheme investor and suggest practical measures to manage financial risks, emotionally. 相似文献

Product management is one of the most important functions in marketing. Yet the product management literature has focused largely on creating successful products and has relatively little to say about creating effective product management organizations. This paper focuses on the organizational determinants of high‐performance product management at three levels: (1) the product manager as an individual; (2) the marketing processes related to product management; and (3) the organization structure and role definition. The paper identifies several key factors that potentially impact product management performance. A set of qualitative interviews is conducted to develop hypotheses related to constructs that may drive product management performance. These hypotheses are used to develop a causal model for product management performance that includes constructs related to roles and responsibilities, organization structure, and marketing processes related to product management. An empirical survey of 198 product managers from a variety of industries is conducted to test the causal model. The results of the causal model suggest that performance of a product management organization is driven by structural barriers in the organization, the quality of marketing processes, roles and responsibilities, and knowledge and competencies. The findings suggest that structural boundaries and interfaces are the biggest impediment to effective product management, followed by clarity of roles and responsibilities. The research highlights the importance of organization structure and effective human resource practices in improving product management performance. 相似文献

We explore the relation between two ‘rationality conditions’ for stochastic choice behavior: regularity and the weak axiom
of stochastic revealed preference (WASRP). We show that WASRP implies regularity, but the converse is not true. We identify
a restriction on the domain of the stochastic choice function, which suffices for regularity to imply WASRP. When the universal
set of alternatives is finite, this restriction is also necessary for regularity to imply WASRP. Furthermore, we identify
necessary and sufficient domain restrictions for regularity to imply WASRP, when the universal set of alternatives is finite
and stochastic choice functions are all degenerate. Results in the traditional, deterministic, framework regarding the relation
between Chernoff’s condition and the weak axiom of revealed preference follow as special cases. Thus, general conditions are
established, under which regularity can substitute for WASRP as the axiomatic foundation for a theory of choice behavior. 相似文献

This paper investigates the determinants of demand for schooling in Kenya. Probit and ordered probit methods are used to model enrolment and attainment respectively. The results show that child characteristics, parental education and other household characteristics, quality and cost of schooling are important determinants of demand for education services in Kenya. The results further show that girls would be more affected by policy changes than boys. The findings call for targeting in efforts to boost and sustain demand for schooling in Kenya. The study recommends immediate policy interventions focusing on improving quality of education and poverty alleviation. 相似文献

Which policy objective should a central bank pursue in a monetary union with asymmetric monetary transmission and different rates of inflation? Should it base its decisions on the EU‐wide average of inflation and growth or should it instead focus on (appropriately weighted) national utility losses based on national rates of inflation and growth? We find that a policy which minimises the sum of national utility losses leads to higher average utility if the variability of common shocks is large relative to idiosyncratic demand shocks in the non‐tradables sectors. We draw conclusions for the appropriate weight of common and national objectives in the union. 相似文献

It is the main aim of our paper to study network formation in experimental setups in discrete and continuous time. Our design
is inspired by the theoretical model on network formation by Bala and Goyal (Econometrica, 68(5): 1181–1229, 2000) as well as the experiments by Callander and Plott (J. Public Econ., 89: 1469–1495, 2005) and Falk and Kosfeld (IEW Working Paper, University of Zürich, Zürich, Switzerland, No. 146, 2003). In particular, we analyze the role of star-shaped networks which are strict Nash-equilibria of the corresponding network
formation game. Our experimental results show that strict Nash networks prove to be a good indicator for predicting network
formation, particularly in continuous time. In explaining our results, it turns out that, among others, the complexity in
coordinating on stars, the inequity aversion against unequal payoff distribution in the network, and the groups’ degrees of
activity are the most important determinants for the formation of strict Nash networks.

This research seeks to identify the importance of various capabilities and psychosociological factors of hotel managers, in order to improve their perception of the competitive environment emerging in the post-Internet era. Specifically, the study analyzes the relevance of education, experience, globalization capabilities, networking, creativity and vision of the future, and other factors related to personality and leadership, to advance the accuracy of this perception. The research used questionnaires with Spanish hotel managers, a Delphi study with international experts, and structural equation modeling to test the hypotheses formulated. The results corroborate the model established, and stress the importance of the education and globalization capabilities in this field. 相似文献
