During the early years of its existence, the National Bureau of Economic Research (NBER) assembled an extensive data set on all aspects of the pre-WWII macroeconomy. Until 1978, this data set existed only on the handwritten sheets to which the early NBER researchers copied the data from original...

In this paper, I present two different methods that can be used to obtain a concise set of descriptive results about the comovement of variables. The statistics are easy to interpret and capture important information about the dynamics in the system that would be lost if one focused only on the...

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...

We ask two questions related to how access to credit affects the nature of business cycles. First, does the standard theory of unsecured credit account for the high volatility and procyclicality of credit and the high volatility and countercyclicality of bankruptcy filings found in U.S. data?...

Economic variables are known to move asymmetrically over the business cycle: quickly and sharply during crises, but slowly and gradually during recoveries. Not known is the fact that this asymmetry is stronger in countries with less-developed financial systems. This new fact is documented using...

In the U.S. economy over the past twenty five years, house prices exhibit fluctuations considerably larger than house rents and these large fluctuations tend to move together with business cycles. We build a simple theoretical model to characterize these observations by showing the tight...

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,...
