Wholly foreign multinational enterprises (WFs), joint-venture multinationals (JVs), state-owned enterprises (SOEs) pay higher wages than domestic private firms in Vietnamese manufacturing. In large samples of medium–large (20+ employees) firms, conditional differentials accounting for worker education and occupation, as well as capital intensity, size, and shares of female workers, were substantially smaller, but positive and significant. Wage levels and differentials varied substantially among industries. Conditional differentials remained positive and significant for WFs and JVs in most of the 11 industries examined, but estimates of SOE-private differentials were insignificant in most industries. Robustness checks using 2007 data yielded similar results.  相似文献

This paper studies goodness-of-fit tests for the bivariate Poisson distribution. Specifically, we propose and study several Cramér–von Mises type tests based on the empirical probability generating function. They are consistent against fixed alternatives for adequate choices of the weight function involved in their definition. They are also able to detect local alternatives converging to the null at a certain rate. The bootstrap can be used to consistently estimate the null distribution of the test statistics. A simulation study investigates the goodness of the bootstrap approximation and compares their powers for finite sample sizes. Extensions for testing goodness-of-fit for the multivariate Poisson distribution are also discussed.  相似文献

This article represents an analysis of and comments on the results of a regular survey of Russian enterprises operating in the real sector, which was conducted by the Institute of Economic Forecasting, Russian Academy of Sciences. It represents opinions of enterprises, the modern macroeconomic problems of which they believe to be the most acute. This article considers the responses of enterprises regarding how their activities have been affected by the mutual sanctions between Russia and Western countries, as well as by Russia’s WTO accession. We have shown the opinions of enterprises on their interests in the ruble exchange rate. This ref lects the current situation with the workforce at enterprises and gives data on their participation in solving of housing problems faced by their employees. This article contains information on how enterprises rate today’s level of competition with foreign manufacturers on Russian markets.  相似文献

This paper investigates whether and to what extent group identity plays a role in peer effects on risk behaviour. We run a laboratory experiment in which different levels of group identity are induced through different matching protocols (random or based on individual painting preferences) and the possibility to interact with group members via an online chat in a group task. Risk behaviour is measured by using the Bomb Risk Elicitation Task and peer influence is introduced by giving subjects feedback regarding group members’ previous decisions. We find that subjects are affected by their peers when taking decisions and that group identity influences the magnitude of peer effects: painting preferences matching significantly reduces the heterogeneity in risk behaviour compared with random matching. On the other hand, introducing a group task has no significant effect on behaviour, possibly because interaction does not always contribute to enhancing group identity. Finally, relative riskiness within the group matters and individuals whose peers are riskier than they are take on average riskier decisions, even when controlling for regression to the mean.  相似文献

In a crisis communication context, this work examines the impact of Psychological Ownership (PO) appeals on Ad message recipients’ development of feelings of PO. It demonstrates that increased levels of PO influence the managerially relevant outcomes attitude toward the company and purchase intentions. In doing so, it finds new application for the construct. In order to better understand the factors that may contribute to or mitigate PO, this research also investigates environmental consciousness as an additional antecedent and gender, persuasion knowledge, and geographic distance as moderators of individuals’ response to such appeals. Managerial and theoretical implications are discussed.  相似文献

In the presence of an endogenous binary treatment and a valid binary instrument, causal effects are point identified only for the subpopulation of compliers, given that the treatment is monotone in the instrument. With the exception of the entire population, causal inference for further subpopulations has been widely ignored in econometrics. We invoke treatment monotonicity and/or dominance assumptions to derive sharp bounds on the average treatment effects on the treated, as well as on other groups. Furthermore, we use our methods to assess the educational impact of a school voucher program in Colombia and discuss testable implications of our assumptions.

Five billion people in the world do not have the kind of ledgers that provide the documented information that allows them to transfer, partition, and aggregate assets and talents in such a way that they can be scaled up, secure investment, guarantee credit, certify reputation, and capture abstract surplus value. The difficulty that most people have in making combinations is a major cause of global inequality and unnecessary poverty.  相似文献

This paper traces between-group earnings inequality for six Latin American countries over two centuries based on wage and income series compiled from a large array of primary and secondary sources. We find that inequality varied substantially by country and by period, questioning the notion that colonial legacies largely dominated the evolution of inequality. There is a broader inequality trajectory over the long run in the form of an “m” pattern with peaks around 1880 and the 1990s and a trough around 1920/1930s. Export-led growth does not necessarily imply a rise in inequality, while the import-substitution industrialisation efforts did not translate into a more egalitarian distribution of income. More notably, Latin America’s experience does not exhibit the great inequality levelling as seen in the North Atlantic economies from the 1930s to the 1970s.  相似文献
