Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...

We construct a model of revolution and transition to democracy under individualistic and collectivist cultures. The main result is that, despite facing potentially larger collective action problems, countries with an individualistic culture are more likely to end up adopting democracy earlier...

Using a unique dataset of daily U.S. and U.K. price listings and the associated number of clicks for precisely defined goods from a major shopping platform, we shed new light on how prices are set in online markets, which have a number of special properties such as low search costs, low costs of...

We document basic facts about prices in online markets in the U.S. and Canada, a rapidly growing segment of the retail sector. Relative to prices in regular stores, prices in online markets are more flexible as well as exhibit stronger pass-through (60-75 percent) and faster convergence...

We study the cyclical properties of sales, regular price changes and average prices paid by consumers ("effective" prices) in a dataset containing prices and quantities sold for numerous retailers across a variety of U.S. metropolitan areas. Both the frequency and size of sales fall when local...

We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures....

This paper estimates how overall consumer spending responds to changes in gasoline prices. It uses the differential impact across consumers of the sudden, large drop in gasoline prices in 2014 for identification. This estimation strategy is implemented using comprehensive, high-frequency...

Recently, Blanchard and Kremer (BK) argued that disorganization has led to the output decline in the former Soviet Union. In this paper we introduce liquidity and credit constraints into the BK model and show how these problems can alleviate the hold-up problem. We argue further that barter...
