We study the relationship between (log) hourly earnings and schooling for male household heads in Italy, using cross-sectional data from the 1993 and 1995 waves of the Bank of Italy (BI) survey on the income and wealth of Italian households. In line with international evidence, we find that OLS under-estimate the return to schooling. When the endogeneity of schooling is taken into account, the return to an additional year in school increases from 4.8% to 5.6%. This estimate is lower than the estimates tabulated by Card [Card, D., 1994. Earnings, Schooling and Ability Revisited. NBER Working Paper no. 4832.] for the United States. We also find evidence that this return increases with higher levels of educational attainment. 相似文献

An ‘innovative activity matrix’ is established from a recent ISTAT/CNR survey of innovation. After specifying the particularities of an innovative activity matrix in comparison with other flow matrices, we show that it is asymmetrical and clustered in parts of economic space. The structure of the innovative activity matrix is similar to that of the domestic and import requirement but not the capital flow matrix. Strong correlations indicate the following: that input–output analysis is useful for identifying the location of innovative activities in economic space; that it can be analyzed in an economically meaningful way; that its location is structured; and that, furthermore, it is structured in ways which are statistically related to economic activity. The paper ends with suggestions for the examination of possible causal relationships. 相似文献

Firms with widely-held ownership are relatively few. Shareholders controlling a firm are willing to forego the benefit of portfolio diversification because they can obtain a ‘rent from control’ at the expense of minority shareholders. This entails relevant conclusions for financial theory: (1) the total market value of a closely-held firm is lower, and its cost of capital higher than that of an identical widely-held firm is lower and its cost of capital higher than that of (3) different prices of control and minority shares and disconuities may impede evolution from closely to widely-held ownership. 相似文献

In a panel data model with random effects, when autocorrelation in the error is considered, (Gaussian) maximum likelihood estimation produces a dramatically large number of corner solutions: the variance of the random effect appears (incorrectly) to be zero, and a larger autocorrelation is (incorrectly) assigned to the idiosyncratic component. Thus heterogeneity could (incorrectly) be lost in applications to panel data with customarily available time dimension, even in a correctly specified model. The problem occurs in linear as well as nonlinear models. This article aims at pointing out how serious this problem can be (largely neglected by the panel data literature). A set of Monte Carlo experiments is conducted to highlight its relevance, and we explain this unpleasant effect showing that, along a direction, the expected log-likelihood is nearly flat. 相似文献

This paper examines the dynamics of income distribution and convergence in Latin America during the period 1960 to 2000. Our
results, based on the intradistribution dynamics approach, reveal a “twin peaks” dynamics, which echoes findings reported
for the OECD, the Asia Pacific Basin and worldwide. Notable differences, however, are found between the income dynamics in
Latin America and in these other regions. Further, our findings indicate that physical capital investment and health capital
serve to explain Latin America’s “twin peaks” polarization. Other factors, such as geographical proximity, trade openness
and human capital, are also found to help explaining it to some extent.
We gratefully acknowledge the helpful comments and suggestions of the referee. 相似文献
