We analyze an equilibrium search model with three sources for wage and unemployment differentials among workers with the same (observed) human capital but different appearance (race): unobserved productivity, search intensities, and discrimination due to an appearance‐based employer disutility factor. We show that the structural parameters are identified using labor market survey data. Estimation results for a black and white high school graduate sample imply: black productivity is 3.3% lower than white productivity; the employer's disutility factor is 31% of the white's productivity level; and 56% of firms have a disutility factor toward blacks. 相似文献

This paper analyzes the effect of terror on the economy. Terror endangers life such that the value of the future relative to the present is reduced. Hence, due to a rise in terror activity, investment goes down, and in the long run income and consumption go down as well. Governments can offset terror by putting tax revenues into the production of security. Facing a tide in terror, a government that acts optimally increases the proportion of output spent on defense, but does not fully offset the tide. Thus, when terror peaks the long run equilibrium with an optimizing government is of lower output and welfare. Next, we show that this theory of terror and the economy, helps to understand changes in trend and business cycle of the Israeli economy. The estimates show that terror has a large impact on the aggregate economy. Continued terror, at the level of the death toll by about the same size as due to car accidents, is expected to decrease annual consumption per capita by about 5% in 2004. Had Israel not suffered from terror during the last 3 years, we estimate that the output per capita would have been 10% higher than it is today. 相似文献

This study examined cancellation policies and their role in shaping travelers’ deal-seeking behavior, exploring the impact of cancellation fees and deadlines on three, mutually exclusive, customers’ hotel booking behavior categories: “Book”, “Book and Search”, and “Search”. 291 subjects, who participated in a week long online “booking game”, attempted to book a room in a virtual hotel and get the best deal. The results were tested using small sample t-test for comparing proportions between two independent populations, non-parametric multiple pairwise comparisons, and multinomial logit regression models. The findings indicate that the cancellation deadline affected participants’ behavior while the size of the cancellation fee had no statistically significant impact. In addition, there was no significant difference between lenient cancellation deadline and no cancellation policy. 相似文献

We consider the following abstraction of competing publications. There are n players in the game. Each player i chooses a point xi in the interval [0,1], and a player's payoff is the distance from its point xi to the next larger point, or to 1 if xi is the largest. For this game, we give a complete characterization of the Nash equilibrium for the two-player game, and, more important, we give an efficient approximation algorithm to compute numerically the symmetric Nash equilibrium for the n-player game. The approximation is computed via a discrete version of the game. In both cases, we show that the (symmetric) equilibrium is unique. Our algorithmic approach to the n-player game is non-standard in that it does not involve solving a system of differential equations. We believe that our techniques can be useful in the analysis of other timing games. 相似文献

This article analyzes the labor mobility and human capital accumulation of male immigrants from the former Soviet Union to Israel. We estimate a dynamic choice model for employment and training in blue‐ and white‐collar occupations, where the labor market randomly offered opportunities are affected by past choices. The estimated model accurately reproduces the patterns in the data. The estimated direct earning return to local training, local experience, and knowledge of Hebrew are very high, whereas imported skills have zero (conditional) return. The welfare gain from the impact of training on job offer probabilities is larger than its effect on wages. 相似文献

Measurement and prediction of salesmen's performance are perennial interests of marketing researchers [1, 5, 6]. The question of the criteria used to evaluate salesmen and the relationship between these criteria and the salesmen's career cycle, however, has yet to be systematically analyzed [4, 10]. The salesman's role includes several tasks, some of which impose conflicting demands upon him. This article explores the implications of conflicting demands on the performance of the role of a salesman, and considers their affect on his career path. 相似文献

When panel data are not available, retrospective data are used in the estimation of dynamic choice models. However, retrospective data are not reliable. Previous studies of voting choices, for example, have shown that respondents misreport their past choices in order to appear more consistent with their current choice. Such retrospective bias leads to inconsistent estimates, especially when there is state dependence in choices. Specifically, observed persistence in retrospective data may be due to (a) true state dependence, (b) unobserved heterogeneity, and (c) retrospective bias in reporting previous choices. Whereas Heckman in his 1981 study deals with (a) and (b), we introduce a method to estimate true state dependence while accounting for both unobserved heterogeneity and retrospective reporting bias. Our method is based on modeling the reporting behavior and integrating it into the estimation. The identification strategy is based on the correlation between the reported previous choices and current exogenous variables. Using data on Israeli voters, we find that the probability that a respondent whose vote intention in 1991 differed from his or her past voting choices would lie about their past choices is 0.23.

Firm size and export performance 总被引:1,自引:0,他引:1
Economic analysis based on the Theory of the Firm shows that the exporting firm can be conceptualized as a discriminating monopolist, facing several demand curves. The analysis shows that under these conditions, and assuming certainty, the larger the firm, the higher the ratio of exports to total sales.When uncertainty is introduced into the model, the conclusion regarding the relationship between size and the ratio of exports to sales is reinforced. Large firms can afford to assume more risks than small ones; in addition, their risks from foreign operations are less than those of small firms because the large firms benefit from economies of scale in foreign marketing. Consequently, the risk premium demanded by large firms from foreign marketing is less than the premium insisted upon by small firms. Large firms therefore tend to export a higher share of their output. These theoretical constructs are confirmed by empirical analysis performed on a sample of several hundred firms from six industries in Denmark, Holland and Israel. The figures confirm, with few exceptions, that the size of firms is indeed positively correlated with the ratio of exports to sales.The normative conclusion which can be drawn from the above is that economic policy-makers who wish to increase the export potential of industrial firms, should adopt policies which will encourage large firms to come into being through mergers, take-overs or simply fast growth. 相似文献
