We address the ordinality of test scores by rescaling them by the average eventual educational attainment of students with a given test score in a given grade. We show that measurement error in test scores causes this approach to underestimate the black-white test score gap and use an...

This paper provides new evidence on the interaction between patient information and financial incentives in physician induced demand (PID). Using rich microdata on childbirth, we compare the treatment of physicians when they are patients with that of comparable non-physicians. We exploit a...

Iodine deficiency is the leading cause of preventable mental retardation in the world today. The condition, which was common in the developed world until the introduction of iodized salt in the 1920s, is connected to low iodine levels in the soil and water. We examine the impact of salt...

We present the main stylized facts of the new international financial landscape in which external balance sheets of countries have grown in...

This paper investigates how public equity issuance is related to stock market liquidity. Using quarterly data on IPOs and SEOs in 36 countries over the period 1995-2008, we show that equity issuance is significantly and positively related to contemporaneous and lagged innovations in aggregate...

We investigate the role of physician agency and competition in determining health care supply and patient outcomes. A 2005 change to Medicare fees had a large, negative impact on physician profit margins for providing chemotherapy treatment. In response to these cuts, physicians increased their...

Why have some poor countries been able to take off while others are still stuck in the poverty trap? To address this old question, we observe that (i) with similar or higher levels of educational attainment, trapped countries tend to have much poorer health conditions compared to the initially...

Many countries have large future public liabilities attributable to health care programs. However, little explicit analysis exists about how health care policies affect these program liabilities. We analyze how reimbursement and approval policies affect public liabilities through their impact on...

The 1990s Sudden Stops in emerging markets were a harbinger for the 2008 global financial crisis. During Sudden Stops, countries lost access to credit, causing abrupt current account reversals, and suffered Great Recessions. This paper reviews a class of models that yields quantitative...
