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...

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...

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...

This paper analyses the effects of open market operations on interest rates in a model in which agents must pay a fixed cost to exchange assets and cash. Asset markets are endogenously segmented in that some agents choose to pay the fixed cost and some do not. When the fixed cost is zero, the...

Fluctuations of business activity in the United States clearly have their monetary and financial side, but these aspects of U.S. economic fluctuations exhibit few quantitative regularities that have persisted unchanged across spans of tine over which the nation's financial markets have...

This paper analyzes the effects of real income and price level uncertainty on equilibrium interest rates. It is demonstrated that even if there are no outside nominal assets, the interest rate on nominal bonds contains a risk premium, or as the case may be, a risk discount. The sign, and the...

We propose a novel measure of risk perceptions: the price of volatile stocks (PVS_t), defined as the book-to-market ratio of low-volatility stocks minus the book-to-market ratio of high-volatility stocks. PVS_t is high when perceived risk directly measured from surveys and option prices is low....

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...

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...
