We study the target projection dynamic, a model of learning in normal form games. The dynamic is given a microeconomic foundation in terms of myopic optimization under control costs due to a certain status-quo bias. We establish a number of desirable properties of the dynamic: existence, uniqueness and continuity of solution trajectories, Nash stationarity, positive correlation with payoffs, and innovation. Sufficient conditions are provided under which strictly dominated strategies are wiped out. Finally, some stability results are provided for special classes of games. 相似文献

The literature on agricultural markets suggests that transactions costs are the main obstacles preventing households from participating in agricultural markets. We examine the impact of the recent massive penetration of information communication technologies (ICTs), particularly mobile phones and radios, in developing countries to investigate the role of information in economic transactions and participation in food crop markets. To fully capture market participation behaviours, the current theoretical framework on market participation and transactions costs is extended to include those households that sell and buy in the same time period. We correct for endogeneity and selectivity throughout our models. We used a novel dataset of 393 households in northern Ghana with detailed information on market transactions and ICTs usage. Results show that receiving market information via mobile phones has a positive and significant impact on market participation, with a greater impact for households with a surplus of food crops. We find that radios have a larger impact on the quantity traded. This may reflect the nature of mobile phones in reducing searching costs, whereas radios provide an updated and regular flow of information which affects the pattern of crops consumed and sold. We also emphasise that the most significant factor is how ICTs are used, rather than their ownership. 相似文献

Drawing from neo-institutional theory, we examine the relationship between preference for entrepreneurship and actual entrepreneurship behavior across multiple countries and cultures. We elucidate how multiple societal-level cultural models, namely Hofstede, Global Leadership and Organizational Behavior Effectiveness (GLOBE), and Schwartz affect the individual-level process connecting expressed preference for self-employment and actual behavior. Our hypotheses were tested using a multilevel technique on a sample of 20,755 individuals across 24 countries. The findings indicate that the moderating effect of predominant cultural cognition is partially supported. Contributions and implications for theory and practice are also discussed. 相似文献

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented. 相似文献

We reassess Mankiw, Romer and Weil's [mrw] version of the Solow model using, as did mrw, cross-sectional data to estimate the steady-state equation governing income per capita levels. The model fails in two critical
areas. First, plausible factor shares obtained by mrw are not robust to the substitution of two measures of human capital that are more precise than the secondary school enrollment
rates used by mrw. Second, the null hypothesis of an exogenous and identical level of technology in all countries is rejected. We also explain
why the Solow model performed well despite the above shortcomings. 相似文献

Can the story of evolving Federal Reserve beliefs in The Conquest of American Inflation simultaneously explain the Great Inflation and the forecasts published in the Greenbook during that time? If Sargent is correct then evolving beliefs should be reflected not only in policy outcomes but also in Greenbook forecasts. In this paper they are. By conditioning on the Greenbook, it is show that both inflation outcomes and Greenbook forecasts can be rationalised by evolving beliefs. The results improve on recent empirical evidence that has been criticised for relying on unrealistic beliefs that produce forecasts inconsistent with the Greenbook. 相似文献

Cheating is an epidemic in higher education. The author examined the psychological variable of academic entitlement and its relationship with the ethical perception of cheating using a sample of business students. Contrary to some previous research, the author found that millennials were only slightly more academically entitled than students from other generations but overall had a low sense of entitlement. Highly entitled business students viewed cheating actions as less unethical compared with less entitled students. 相似文献
