Path Dependence and Occupations

Path dependence in occupations refers to the observed occupational distribution in a population or in a sub-population at a point in time that depends on changes that occurred years or centuries earlier. Path dependence in occupations can be the outcome of the cumulative concentration of certain productive activities in specific regions over time, it can emerge through the effect of parental income or wealth on offspring’s occupations and incomes, or it can be the outcome of group effects. Some historical cases are selected to illustrate the various mechanisms through which path dependence in occupations can emerge or disappear.path dependence, occupational structure, social norms, trade diasporas, Jewish occupational selection, feminization of occupations, African-American occupational transition

From Farmers to Merchants, Voluntary Conversion and Diaspora: A Human Capital Interpretation of Jewish History

From the end of the second century C.E., Judaism enforced a religious norm requiring any Jewish father to educate his children. We present evidence supporting our thesis that this exogenous change in the religious and social norm had a major influence on Jewish economic and demographic history. First, the high individual and community cost of educating children in subsistence farming economies (2nd to 7th centuries) prompted voluntary conversions, which account for a large share of the reduction in the size of the Jewish population from about 4.5 million to 1.2 million. Second, the Jewish farmers who invested in education, gained the comparative advantage and incentive to enter skilled occupations during the vast urbanization in the newly developed Muslim Empire (7th and 8th centuries) and they actually did select themselves into these occupations. Third, as merchants the Jews invested even more in education–a pre-condition for the extensive mailing network and common court system that endowed them with trading skills demanded all over the world. Fourth, the Jews generated a voluntary diaspora by migrating within the Muslim Empire, and later to western Europe where they were invited to settle as high skill intermediaries by local rulers. By 1200, the Jews were living in hundreds of towns from England and Spain in the West to China and India in the East. Fifth, the majority of world Jewry (about one million) lived in the Near East when the Mongol invasions in the 1250s brought this region back to a subsistence farming economy in which many Jews found it difficult to enforce the religious norm regarding education, and hence, voluntarily converted, exactly as it had happened centuries earlier.social norms, religion, human capital, Jewish economic and demographic history, occupational choice, migration.

The evolution of U.S. earnings inequality: 1961?2002

The goal of this article is to summarize the main trends in the earnings and employment distribution in the United States using data drawn from the March Current Population Surveys covering the period between 1961 and 2002. We show that inequality started to increase for men in 1974, and for women in 1981, and for both genders inequality continued to increase throughout 2002. During the same period the wage premium of college graduates over non-college workers increased substantially and the ratio of college educated workers to non-college workers also increased. These facts support the popular skill-biased technical change (SBTC) hypothesis. However, other facts raise some doubts about the SBTC hypothesis. First, the college wage premium is mainly due to workers with a postgraduate degree, but their increase in the labor force started much earlier than the spectacular rise in their wages. Also there has been no marked change in recent decades in the occupational distribution of workers. However, the earning premium of professional over blue collar workers followed the same trend as the college earning premium. And finally, the most dramatic changes in the labor market took place among women.Income distribution

Dynamic Female Labor Supply

The increase in female employment and participation rates is one of the most dramatic economic changes to have taken place during the last century. However, while the employment rate of married women more than doubled during the last fifty years, that of unmarried women remained almost constant. In order to empirically analyze these trends we divide the paper into two parts: In the first, we empirically estimate a traditional female dynamic labor supply model using an extended version of Eckstein and Wolpin (1989) in order to compare the various explanations in the literature for the observed trends. The main finding is that the rise in education levels accounts for about one-third of the increase in female employment while about 40 percent remains unexplained by observed household characteristics. We show that this unexplained portion can be empirically attributed to changes in preferences or the costs of childrearing and household maintenance. In the second part, we formulate and estimate a new framework for the couple intra-family game that is then used to analyze the household dynamic labor supply. We find that female labor supply may have increased significantly due to a change in the form of the household game.dynamic discrete choice, female employment, accounting, household game

Transaction services, inflation, and welfare

This paper is motivated by empirical observations on the comovements of currency velocity, inflation, and the relative size of the credit services sector. We document these comovements and incorporate into a monetary growth model a credit services sector that provides services that help people economize on money. Our model makes two new contributions. First, we show that direct evidence on the appropriately defined credit service sector for the United States is consistent with the welfare cost measured using an estimated money demand schedule. Second, we provide welfare cost of inflation estimates that have some new features.Inflation (Finance) ; Welfare
