We present a model of shadow banking in which financial intermediaries originate and trade loans, assemble these loans into diversified portfolios, and then finance these portfolios externally with riskless debt. In this model: i) outside investor wealth drives the demand for riskless debt and...

We examine the productivity of informal firms (those that are not registered with the government) in 24 African countries using field work and World Bank firm level data. We find that productivity jumps sharply if we compare small formal firms to informal firms, and rises rapidly with the size...

In developing countries, informal firms (those that are not registered with the government) account for about half of all economic activity. We consider three broad views of the role of such firms in economic development. According to the romantic view, these firms would become the engine of...

This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer...

Considerable debate rages about whether Federal Reserve policy was too lax in the early part of the 2000s, thereby fueling the home-price bubble that was the proximate cause of the global financial crisis. We present evidence that the view that modest alterations to monetary policy have vast...

We present a monetary model in the presence of segmented asset markets that implies a persistent fall in interest rates after a once and for all increase in liquidity. The gradual propagation mechanism produced by our model is novel in the literature. We provide an analytical characterization of...

We provide the first empirical tests for financial protectionism, defined as a nationalistic change in banks' lending behaviour, as the result of public intervention, which leads domestic banks either to lend less or at higher interest rates to foreigners. We use a bank-level panel data set...

The confluence of three trends in the U.S. residential housing market---rising home prices, declining interest rates, and near-frictionless refinancing opportunities---led to vastly increased systemic risk in the financial system. Individually, each of these trends is benign, but when they occur...

I extend the methods of G ̈urkaynak, Sack, and Swanson (2005) to separately identify the effects of Federal Reserve forward guidance and large-scale asset purchases (LSAPs) during the 2009–15 U.S. zero lower bound (ZLB) period. I find that both forward guidance and LSAPs had substantial and...

We use the founding of the Federal Reserve as a historical experiment to provide some insight into whether a lender of last resort can stabilize financial markets. Following the Panic of 1907, Congress passed two measures that established a lender of last resort in the United States: (1) the...
