Cities are shaped by transportation infrastructure. Older cities were anchored by waterways. Nineteenth century cities followed the path of streetcars and subways. The 20th century city rebuilt itself around the car. The close connection between transportation and urban form is natural, since...

U.S. cities invested heavily in water and sewer infrastructure throughout the late 19th and early 20th centuries. These investments improved public health and quality of life by helping U.S. cities control typhoid fever and other waterborne diseases. We show that segregated cities invested in...

Between 1900 and 1930 typhoid fever and other waterborne diseases were largely eradicated from U.S. cities. This achievement required a mix of technological, scientific, economic, and bureaucratic innovations. This article examines how the interaction of those forces influenced water and...

Recent work in the sociology of economic development has emphasized the establishment of a professional bureaucracy in place of political appointees as an important component of the institutional environment in which private enterprise can flourish. I hypothesize that establishment of such a...

Over the last two decades, the unprecedented increase in non-bank financial intermediation, particularly open-end mutual funds and ETFs, accounts for nearly half of the external financing flows to emerging markets exceeding cross-border lending by global banks. Evidence suggests that investment...

We use unique firm-level data from Mexico to document that non-financial corporations engage in carry trades by borrowing in foreign currency (FX) and lending in domestic currency, largely in the form of trade credit, accumulating currency risk in the process. We show at a quarterly frequency...

Recent theories of exchange rate determination have emphasized limited UIP arbitrage by international financial institutions. New regulations since 2008 have also lead to imperfect CIP arbitrage. We show that under limited CIP arbitrage the exchange rate and CIP deviation are jointly determined...

We review the literature on financial intermediation in the process by which new medical therapeutics are financed, developed, and delivered. We discuss the contributing factors that lead to a key finding in the literature--underinvestment in biomedical R&D--and focus on the role that banks and...

Nonbank lenders have been playing an increasing role in supplying debt, especially after the Great Recession. How important are the distortions in the greater regulation of banks that differentially limit risk-taking across alternative providers of credit? How might the growing role of nonbanks...

The traditional model of bank-led financial intermediation, where banks issue demandable deposits to savers and make informationally sensitive loans to borrowers, has seen a dramatic decline since 1970s. Instead, private credit is increasingly intermediated through arms-length transactions, such...
