Were ordinary factory workers unskilled and was technology “de-skilling” during the Industrial Revolution? I measure foregone output to estimate the human capital investments in mule spinners and power loom tenders in ante-bellum Lowell. These investments rivaled those of craft apprentices. Although factory workers were unskilled in a sense, the implementation of this technology depended on the...

This paper sheds light on the transferability of human capital in periods of dramatic structural change by analyzing the unique event of German Reunification. We explore whether the comparatively low labor productivity in East Germany after reunification is caused by the depreciation of human capital at reunification, or by unfavorable job characteristics. East German workers should have been h...

An incomplete markets life-cycle model with indivisible labor makes career lengths and human capital accumulation respond to labor tax rates and government supplied non-employment benefits. We compare aggregate and individual outcomes in this individualistic incomplete markets model with those in a comparable collectivist representative family with employment lotteries and complete insurance ma...

Premature delivery occurs in 12% of all births, accounts for nearly half of neonatal morbidity and is increasing in frequency. Current therapeutic approaches to preterm delivery are ineffective and present serious risks to both the mother and fetus. Although there are multiple factors that contribute to the etiology of preterm birth, the single most common cause is infection. Recently, using cD...

The principal difference between term and preterm labor is how they are activated. It has been proposed that term labor results from physiological activation of the common terminal pathway, whereas preterm labor is a pathological condition caused by multiple etiologies that activate one or more of the components of this pathway. Increased uterine contractility at preterm labor results from acti...

Human Capital, Economic Growth, and Inequality in China China’s rapid growth was fueled by substantial physical capital investments applied to a large stock of medium skilled labor acquired before economic reforms began. As development proceeded, the demand for high skilled labor has grown, and, in the past decade, China has made substantial investments in producing it. The egalitarian access t...

This paper uses a two-region, two-period overlapping generations model with international labor mobility to examine the efficacy of using tax policy to internalize the externalities created by international labor migration. While a brain drain tax has a substantial limiting effect on labor migration and a small negative effect on per worker growth, it is found to be a viable solution to the neg...

Crime has high social costs. The criminal justice system is costly, imprisonments have negative effects on labor force participation, and the pain for victims is significant for most types of crime. Criminal behavior is related to marginal costs and marginal utility that go beyond deterrence and punishment. Economic theory suggests that some policies, for example improved labor market opportuni...

The last few hours of human pregnancy are characterized by uterine contractions that effect dilatation of the cervix and force the fetus through the birth canal. The myometrial contractions of labor are painful, which is why the term labor pains is used to describe this process. Before these forceful, painful contractions begin, however, the uterus must be prepared for labor. During the first 3...
