The paper develops a four sector small open economy model with two traded final good sectors, a public intermediate good producing sector and a nontraded good sector producing varieties of intermediate goods. There are three primary factors: capital, skilled labour and unskilled labour. Industrial sector producing a traded good uses capital, intermediate goods and skilled labour as inputs. Intermediate goods producing sector also uses capital and skilled labour. Public input producing sector and the agricultural sector producing the other traded good use capital and unskilled labour as inputs. It is shown that, if production technologies are the same for the agricultural sector and the public input producing sector and if the scale elasticity of output is very low, then an increase in capital stock (unskilled labour endowment) raises (lowers) the skilled–unskilled wage ratio. However, an increase in skilled labour endowment does not produce any unambiguous effect. On the other hand, an increase in the tax rate on industrial output and/or an increase in the price of the agricultural product, armed with the same set of assumptions, lowers the skilled–unskilled wage ratio.  相似文献

In a model with democratic institutions and three jurisdictions, we study the allocation and welfare in a one-level (unitary) and a two-level (federal) government, given that the central government finds it optimal to discriminate in favor of two jurisdictions and against the third. Favored jurisdictions are at least as well off in a unitary structure as compared to a federal one, while this may not be so for the jurisdiction discriminated against. We finally show that jurisdiction-specific electoral uncertainty is consistent with both equitable as well as discriminating allocations.  相似文献

Summary In this paper two bivariate beta distributions have been studied. The five parameter bivariate beta distribution is derived from the Morgenstern-system of curves while the three parameter distribution is the bivariate Dirichlet distribution. In both cases the distributions of the product and the quotient of random variables are derived and other properties are also studied.  相似文献

ABSTRACT

This research explores the social-cognitive factors which lead both women and men to pursue ventures consistent with their gendered social identity, therefore, reinforcing the gender gap in entrepreneurship. We measured the self-assessments of individuals presented with experimentally manipulated entrepreneurial opportunities that were either consistent or inconsistent with their self-reported gender. A theoretical model derived from Social Role Theory is presented and tested. It posits that a gender match (mismatch) with the entrepreneurial opportunity results in higher (lower) reported self-efficacy, anticipated social resources, and venture desirability and lower (higher) venture risk perceptions. The experimental data are tested in a sequential mediation SEM model. We find evidence that self-efficacy and anticipated social resources mediate the effect of gender congruency on perceived risk and venture desirability. The results provide insight into the insidious barriers that play a role in reproducing a gender gap in entrepreneurial outcomes by ‘nudging’ women into lower-return ventures in less lucrative industries.  相似文献

The mixture of type-I and type-II censoring schemes, called the hybrid censoring scheme is quite common in life-testing or reliability experiments. In this paper, we consider the competing risks model in presence of hybrid censored data. Under this set up, it is assumed that the item may fail due to various causes and the corresponding lifetime distributions are independent and exponentially distributed with different scale parameters. We obtain the maximum likelihood estimators of the mean life of the different causes and derive their exact distributions. Using the exact distributions, all the moments can be obtained. Asymptotic confidence intervals and two bootstrap confidence intervals are also proposed. Bayes estimates and credible intervals of the unknown parameters are obtained under the assumptions of independent inverted gamma priors of the mean life of the different causes. Different methods have been compared using Monte Carlo simulations. Onereal data set has been analyzed for illustrative purposes. Part of the work was supported by a grant from the Natural Sciences and Engineering Research Council.  相似文献

Notwithstanding their concern with intra‐MNC control mechanisms, scholars have overlooked the complementary phenomenon of self‐regulatory behavior by subsidiaries. In this paper, we take the first steps towards addressing this gap by advancing and testing hypotheses dealing with the determinants of a major element of self‐regulatory behavior at the subsidiary level, i.e., the performance‐oriented feedback‐seeking behavior of subsidiary presidents. Utilizing data from 374 subsidiaries of 75 MNCs, we test hypotheses regarding the impact of subsidiary task and organizational context on the feedback‐seeking behavior of subsidiary presidents. The results of this study can be summarized as follows: (i) subsidiary presidents do engage in proactive performance‐oriented feedback‐seeking behavior; (ii) they vary in the extent to which they engage in such behavior; and (iii) these variations in feedback‐seeking behavior are at least partially systematic.

Geopolitical risks and stock market dynamics of the BRICS   总被引:1,自引:0,他引:1  
This paper examines the effect of geopolitical uncertainty on return and volatility dynamics in the BRICS stock markets via nonparametric causality-in-quantiles tests. The effect of geopolitical risks (GPRs) is found to be heterogeneous across the BRICS stock markets, suggesting that news regarding geopolitical tensions do not affect return dynamics in these markets in a uniform way. GPRs are generally found to impact stock market volatility measures rather than returns, and often at return quantiles below the median, indicating the role of GPRs as a driver of bad volatility in these markets. While Russia bears the greatest risk exposure to GPRs in terms of both return and volatility, India is found to be the most resilient BRICS nation in the group. Noting that geopolitical shocks and in particular terrorist incidents are largely unanticipated, our findings underscore the importance of a strong financial sector that can help return the market to stability and an open economy that allows local investors to diversify country-specific risks in their portfolios.  相似文献

Research Summary: The increasing number of women chief executives motivates considerable interest in examining possible gender differences in CEO compensation. Recently, Hill, Upadhyay and Beekun reported that female CEOs receive greater compensation than male CEOs, which runs counter to common wisdom that the gender pay gap in the labor market favors men over women. With the goal of contributing to cumulative knowledge development in this area, we seek to reexamine Hill et al.'s finding about gender differences in CEO compensation by extending the analyses further in time, using a larger sample of firms and more rigorous empirical analyses. Our findings, which are robust to different statistical procedures and econometric specifications, do not reveal reliable evidence for differences in compensation paid to male and female CEOs. Managerial Summary : For years, a lively debate has centered on the issue of gender pay gap. The ubiquity of the pay gap between men and women has recently been questioned by Hill et al. who identify the chief executive officer (CEO) role as a workplace position where women receive greater compensation than men. Our investigation examines whether women CEOs are indeed compensated substantively more than male CEOs. We seek to replicate earlier work by Hill and colleagues, using an expanded dataset over a longer period of time and with more rigorous analytical tools. We do not find reliable evidence for a difference in compensation paid to male and female CEOs, suggesting that claims about gender gap in CEO compensation favoring women over men may be premature.  相似文献
