Economists seeking to improve the efficiency of health care delivery frequently emphasize two issues: the fragmented structure of physician practices and poorly designed physician incentives. This paper analyzes these issues from the perspective of organizational economics. We begin with a brief...

We examine how two highly successful new biotechnology firms (NBFs) source their most critical input -- scientific knowledge. We find that scientists at the two NBFs enter into large numbers of collaborative research efforts with scientists at other organizations, especially universities. Formal...

Audit studies testing for discrimination have been criticized because applicants from different groups may not appear identical to employers. Correspondence studies address this criticism by using fictitious paper applicants whose qualifications can be made identical across groups. However,...

This paper highlights unanswered research questions in the economics of retirement, and shows how these issues can be addressed using the new Health and Retirement Survey (HRS). Unique features of the survey are described including administrative records on earnings and social security benefits,...

Social experiments are powerful sources of information about the effectiveness of interventions. In practice, initial randomization plans are almost always compromised. Multiple hypotheses are frequently tested. "Significant" effects are often reported with p-values that do not account for...

We use Michigan Panel Study of Income Dynamics data and data from a 2008 telephone survey of adults conducted by Westat for the Princeton Data Improvement Initiative (PDII) to explore the importance and feasibility of adding retrospective questions about actual work experience to cross-sectional...

Presenting data on all full-length articles published in the three top general economics journals for one year in each of the 1960s through 2010s, I analyze how patterns of co-authorship, age structure and methodology have changed, and what the possible causes of these changes may have been. The...

Although both economists and psychometricians typically treat them as interval scales, test scores are reported using ordinal scales. Using the Early Childhood Longitudinal Study and the Children of the National Longitudinal Survey, we examine the effect of order-preserving scale transformations...

Economists are increasingly turning to the experimental method as a means to estimate causal effects. By using randomization to identify key treatment effects, theories previously viewed as untestable are now scrutinized, efficacy of public policies are now more easily verified, and stakeholders...
