The overuse of medical services including antibiotics is often blamed on Physician Induced Demand. But since this theory is about physician motivations, it is difficult to test. We conduct an audit study in which physician financial incentives, beliefs about what patients want, and desires to...

This paper investigates the effects of expanding public health insurance eligibility for older children. Using data from the National Health Interview Surveys from 1986 to 2005, we first show that although income continues to be an important predictor of children's health status, the importance...

We ask how patient knowledge of appropriate antibiotic usage affects both physicians prescribing behavior and the physician-patient relationship. We conduct an audit study in which a pair of simulated patients with identical flu-like complaints visits the same physician. Simulated patient A is...

This paper investigates how Confucianism affects individual decision making in Taiwan and in China. We found that Chinese subjects in our experiments became less accepting of Confucian values, such that they became significantly more risk loving, less loss averse, and more impatient after being...

A ubiquitous and largely unquestioned assumption in studies of housing markets is that there is perfect information about local amenities. This paper measures the housing market and health impacts of 1,600 openings and closings of industrial plants that emit toxic pollutants. We find that...

A growing literature documents the links between long-term outcomes and health in the fetal period, infancy, and early childhood. Much of this literature focuses on rich countries, but researchers are increasingly taking advantage of new sources of data and identification to study the long reach...

This paper develops and applies a model in which doctors have two dimensions of skill: diagnostic skill and skill performing procedures. Higher procedural skill increases the use of intensive procedures across the board, while better diagnostic skill results in fewer intensive procedures for the...

This paper provides estimates of the effects of in utero exposure to contaminated drinking water on fetal health. We examine the universe of birth records and drinking water testing results for the state of New Jersey from 1997 to 2007. Our data enable us to compare outcomes across siblings who...

The events of 9/11 released a million tons of toxic dust into lower Manhattan, an unparalleled environmental disaster. It is puzzling then that the literature has shown little effect of fetal exposure to the dust. However, inference is complicated by pre-existing differences between the affected...

There is a large literature suggesting that "WIC works" to improve birth outcomes. However, methodological limitations related to selection into the WIC program have left room for doubt about this conclusion. This paper uses birth records from New York City to address the limitations of the...
