We develop and test a model of the patenting and R&D decisions of an innovating firm whose researcher-employees sometime quit to join or start a rival. In our model, the innovating firm patents to protect itself from its workers. We show theoretically that the risk of a scientist's departure...

We trace the impact of pay-as-you-go (PAYG) social security taxes on demographic and economic trends through an endogenous-growth model where human capital is the engine of growth, family choices affect its formation in children, and family formation itself is a choice variable. We show that...

The 19th century economist Thomas Robert Malthus hypothesized that the long-run supply of labor is completely elastic at a fixed wage-income evel because population growth tends to outstrip real output growth. Dynamic equilibrium with constant income and population is achieved through...

The worldwide problem with pay-as-you-go, defined-benefits social security systems is not just financial. Through a dynamic, overlapping-generations model where forming a family and bearing and educating children are choice variables, we show that social security taxes and benefits generate...

Rapid technological development makes skills depreciate faster than in the past while new technologies generate gaps in workers’ skills and call for the acquisition of proper skills and lifelong learning. Proper skill mixes for future jobs include strong cognitive skills, basic information and...

This study identifies a new mechanism to account for the persistent gender differences in earnings after childbirth. Aside from women's voluntary wage cuts in pursuit of family-friendly job amenities, we claim that adverse labor market conditions at the time of childbearing widen the gender gap...

Investments in emerging technologies, such as quantum computing, are risky. This paper examines whether investing in stocks of companies with high exposure to new technologies leads to potentially high returns. I collect all U.S. patent publications publicized between 1976 and 2021 and their...

Despite unambiguous predictions of the canonical model of a competitive labor market, empirical studies on the labor market effects of payroll taxation provide conflicting evidence. Our meta-analysis shows that varying degrees of labor market competitiveness across places and time could be one...

This paper investigates the determinants of past changes in the labor force of 12 emerging Asian countries, and attempts to make projections of the labor force in those countries for the period 2010-2030. Results from the regression analysis indicate that the labor force has grown faster than...

The worldwide problem with pay-as-you-go (PAYG) social security systems isn't just financial. This study indicates that these systems may have exerted adverse effects on key demographic factors, private savings, and long-term growth rates. Through a comprehensive endogenous-growth model where...
