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...

Over the years, there emerged two key policy differences between Europe and America, both welfare and migration-states. The former has more generous welfare state and more liberal migration policies than the latter. In this paper we attempt to provide a political-economy explanation for these...

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...

Pollution exposure early in life is detrimental to near-term health and an increasing body of evidence suggests that early childhood health influences health and human capital outcomes later in life. This paper reviews the economic research that brings these two literatures together. We begin...

We examine the effects of a policy change in the province of Quebec, Canada which greatly expanded insurance coverage for prescription medications. We show that the change was associated with a sharp increase in the use of stimulant medications commonly prescribed for ADHD in Quebec relative to...

A growing literature suggests that stressful events in pregnancy can have negative effects on birth outcomes. Some of the estimates in this literature may be affected by small samples, omitted variables, endogenous mobility in response to disasters, and errors in the measurement of gestation, as...

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...

We develop a dynamic politico-economic theory of welfare state, featuring three groups of voters: skilled workers, unskilled workers, and old retirees. The welfare-state is modeled by a proportional tax on labor income to finance a demogrant in a balanced-budget manner to capture the essence of...

It is well-known that, in the Mundell-Fleming model, capital mobility creates a channel through which permanent (transitory) shocks to aggregate demand such as fiscal and trade shocks are completely (partially) neutralized by the response of the real exchange rate. An important policy...

We provide an exploratory quantitative analysis of the role of capital mobility and international taxation in explaining the observed cross-country diversity in the long-run rates of growth of per capita and total incomes as well as the population growth rates. Corroborative evidence is found...
