Risk aversion experiments such as those by Holt and Laury (2002, 2005) measure risk aversion by examining subjects’ responses to a series of probability-ordered choices. Subjects are paid real money rewards, using the random round payment method in which the amount is determined by one randomly selected decision. The findings reported here were obtained from 119 subjects who confronted the same choice set and payment amounts, but 60 of these subjects were paid using the random-round method while the remaining 59 were paid based on an average of all their choices, the accumulated value method. The accumulated value payment method simulates portfolio returns, as opposed to returns from stand alone investments. Results indicate that accumulated value subjects took more risk and made more inconsistent decisions.  相似文献

Race relations in New Orleans have often been narrowed to Black and white, especially pre-Katrina. According to the 2000 census, the city was about 67% African American, 27% white, 2% Asian, and 3% “Hispanic.” In a city with a deep history of racial tensions between Black and white, other people of color—and especially recent immigrants—often went unmentioned in discussions of city demographics. The city’s world famous culture—whether in the traditions of Mardi Gras Indians and secondline parades, or in music like jazz and bounce—is also famously rooted in specifically African cultures. Even in media coverage of the city post-Katrina, the story of immigrant experiences has remained mostly invisible. When these stories have been told, they have often fit into the old stereotypes of “model minorities” (as in the case of the Vietnamese recovery) or of low-wage workers stealing jobs (as in the case of news reports on the city’s new Latino population). However, the stories of these other New Orleanians offer an important lens through which to view the overall struggle over the city’s recovery. And the work of grassroots activists from these communities, who strived to not only work for justice for their friends and neighbors, but also to build broad multi-racial alliances, provides an inspiring example for people in other cities who are waging similar fights.  相似文献

This paper develops a non-finite-difference-based method of American option pricing under stochastic volatility by extending the Geske-Johnson compound option scheme. The characteristic function of the underlying state vector is inverted to obtain the vector’s density using a kernel-smoothed fast Fourier transform technique. The method produces option values that are closely in line with the values obtained by finite-difference schemes. It also performs well in an empirical application with traded S&P 100 index options. The method is especially well suited to price a set of options with different strikes on the same underlying asset, which is a task often encountered by practitioners.  相似文献

This study examined the relationship between land inequality and human capital accumulation in the Korean colonial period by using a panel data set from 1934 to 1942. Evidence of the adverse relationship between land inequality and the accumulation of human capital has thus far only been presented by using data from Western countries and from countries that achieved industrialization not under colonial occupation but by their own economic interest. The presented findings thus contribute to the body of knowledge on this topic and confirm the generalizability of the Galor model by analyzing the unique Korean context under Japanese rule in the early twentieth century. It is the first study to present evidence that inequality in landownership had an adverse effect on the level of public education in the Korean colonial period (i.e., it is a non-financial hurdle for human capital accumulation). By using a fixed effects model and a fixed effects two-stage least squares model with an instrumental variable estimation, this study exploits variation in inequality in land concentration across regions in Korea, accounting for the unobserved heterogeneity across these regions. Overall, this analysis establishes a highly significant adverse effect of land inequality on education in the Korean colonial period.  相似文献

Economists and other social scientists are calling for a reassessment of the impact of international trade on labor markets in developed and developing countries. Classical models of globalization and trade, based upon the international exchange of finished goods, fail to capture the fragmentation of much commodity production and the geographical separation of individual production tasks. This fragmentation, captured in the growing volume of intra-industry trade, prompts investigation of the effects of trade within, rather than between, sectors of the economy. In this paper we examine the relationship between international trade and the task structure of US employment. We link disaggregate US trade data from 1972 to 2006, the NBER manufacturing database, the Decennial Census, and occupational and task data from the Dictionary of Occupational Titles. Within-industry shifts in task characteristics are linked to import competition and technological change. Our results suggest that trade has played a major role in the growth in relative demand for nonroutine tasks, particularly those requiring high levels of interpersonal interaction.  相似文献

Job Satisfaction and Contingent Employment   总被引:1,自引:0,他引:1  
This paper analyses job satisfaction as an aggregate of satisfaction with several job aspects, with special focus on the influence of contingent-employment contracts. Fixed-effect analysis is applied on a longitudinal sample of Dutch employees in four work arrangements: regular, fixed-term, on-call and temporary agency work. Our results indicate that temporary agency work is the only contingent employment relation that is on average associated with lower job satisfaction compared to regular workers. Decomposition of this gap indicates that the major part is due to the low satisfaction experienced by agency workers regarding the content of their jobs. A lack of job security is also responsible for part of the gap. For fixed-term and on-call workers the negative satisfaction effect originating from the lack of job security and lower wages is compensated by other job aspects and a variant relationship between total job satisfaction and its components. However, male and high educated on-call workers do experience lower job satisfaction.  相似文献

This paper develops a general equilibrium endogenous growth model that highlights the scale-independent mechanisms through which trade-induced North-South technological-knowledge diffusion affects the technological-knowledge bias and, thus, the paths of intra-country wage inequality. In contrast with the market-size effect, stressed in the previous literature on skill-biased technological change, the operation of the emphasized price channel following openness predicts, in line with the recent trends in developed and developing countries, an increasing skilled technological-knowledge bias, which, in turn, rises wage inequality in favor of skilled labor.  相似文献

This paper estimates product quality at the sectoral level using data from a panel of twelve manufacturing sectors in nineteen OECD countries during the years 1995–2006. The author first derives a gravity model from a firm-heterogeneity model of trade, then measures product quality as the residual of the gravity model. In estimating the gravity model, the author employs the two-step procedure of Helpman et al. (Q J Econ 123(2):441–487, 2008) to correct for biases caused by selection in trade and firm heterogeneity. When aggregated into the country level, the used overall quality metrics do not systematically differ from Hallak and Schott’s (Q J Econ 126(1):417–474, 2011). In line with existing literature, sectoral quality estimates are found positively correlated with sectoral unit prices as well as countries’ income per capita. And the quality gap between rich and poor countries is more pronounced in capital- and skill-intensive sectors. In addition, the autor finds beta- and sigma-convergence in sectoral product quality across countries.  相似文献
