Is there a link between loose monetary conditions, credit growth, house price booms, and financial instability? This paper analyzes the role of interest rates and credit in driving house price booms and busts with data spanning 140 years of modern economic history in the advanced economies. We...

We use a fully-specified neoclassical model augmented with costly external equity as a laboratory to study the relations between stock returns and equity financing decisions. Simulations show that the model can simultaneously and in many cases quantitatively reproduce: procyclical equity issuance;...

Robert Solow has criticized our 2006 Journal of Economic Perspectives essay describing "Modern Macroeconomics in Practice." Solow eloquently voices the commonly heard complaint that too much macroeconomic work today starts with a model with a single type of agent. We argue that modern...

This paper unveils a new resource for macroeconomic research: a long-run dataset covering disaggregated bank credit for 17 advanced economies since 1870. The new data show that the share of mortgages on banks' balance sheets doubled in the course of the 20th century, driven by a sharp rise of...

We examine the evolution of real per capita GDP around 100 systemic banking crises. Part of the costs of these crises owes to the protracted nature of recovery. On average, it takes about eight years to reach the pre-crisis level of income; the median is about 6 ½ years. Five to six years after...

Economic growth involves metamorphosis of the financial system. Forms of banks and bank money change. These changes, if not addressed, leave the banking system vulnerable to crisis. There is no greater challenge in economics than to understand and prevent financial crises. The financial crisis...

We develop a macroeconomic model with adverse selection. A continuum of households purchase goods from a continuum of anonymous producers. The quality of products can only be learned after trade. Adverse selection arises as low-quality goods deliver higher profits for producers but are less...

We use firms' decisions in the cross-section about their sources and uses of funds in order to make inferences about the aggregate cost of external finance. The basic intuition is as follows: Firms which raise costly external finance can invest the issuance proceeds in productive capital assets,...

We present evidence that shocks to household consumption growth are negatively skewed, persistent, countercyclical, and play a major role in driving asset prices. We construct a parsimonious model where heterogeneous households have recursive preferences and a single state variable drives the...

Why did the failure of Lehman Brothers make the financial crisis dramatically worse? The financial crisis was a process of a build-up of risk during the crisis prior to the Lehman failure. Market participants tried to preserve an option or exit by shortening maturities - the "flight from...
