In this paper we present an analytically tractable overlapping generations model of human capital accumulation, and study its implications for the evolution of the U.S. wage distribution from 1970 to 2000. The key feature of the model, and the only source of heterogeneity, is that individuals...

This paper uses a regression discontinuity design to estimate the effect of home computers on child and adolescent outcomes. We collected survey data from households who participated in a unique government program in Romania which allocated vouchers for the purchase of a home computer to...

Using pooled cross-section, time-series data for 44 industries over the decades of the 1960s, 1970s, and 1980s in the United States, I find no econometric evidence that computer investment is positively linked to TFP growth (over and above its inclusion in the TFP measure). However,...

An increasingly influential "technological-discontinuity" paradigm suggests that IT-induced technological changes are rapidly raising productivity while making workers redundant. This paper explores the evidence for this view among the IT-using U.S. manufacturing industries. There is some...

Recent technological changes have been characterized as “routine-substituting,” reducing demand for routine tasks but increasing it for analytical and service tasks. Little is known about how these changes have impacted immigration, or task specialization between immigrants and natives. In...

The recent digitization of complete count census data is an extraordinary opportunity for social scientists to create large longitudinal datasets by linking individuals from one census to another or from other sources to the census. We evaluate different automated methods for record linkage,...

We evaluate whether hospital adoption of electronic medical records (EMRs) leads to increases in billing where financial gains are large or where hassle costs of complete coding are low. The 2007 Medicare payment reform varied both financial incentives and hassle costs of coding. We find no...

Numerous studies on production and cost, the sources of productivity and studies on endogenous growth have recognized the pivotal role of the physical capital stock. Also there is a clear recognition by economists and policy makers that knowledge capital approximated by R&D capital is crucial...
