We study the impact of plausibly exogenous global food price shocks on local violence across the African continent. In food-producing areas, higher food prices reduce conflict over the control of territory (what we call "factor conflict") and increase conflict over the appropriation of surplus...

Corn prices increased sharply in the summer of 2012 due to expected production shortfalls in the United States, which produces roughly 40% of the world's corn. A heat wave in July adversely affected corn production. We extend earlier statistical models of county-level corn yields in the Eastern...

This paper first considers the impact on world food prices of the changes in restrictions on trade in staple foods during the 2008 world food price crisis. Those changes--reductions in import protection or increases in export restraints--were meant to partially insulate domestic markets from the...

Using a sample of 32 developed and developing countries we analyze the empirical characteristics of sudden stops in capital flows and the relevance of balance sheet effects in the likelihood of their materialization. We find that large real exchange rate (RER) fluctuations coming hand in hand...

At the onset of the COVID-19 economic crisis, as in other crisis episodes, the flight to safety was accompanied by a rapid appreciation of “safe haven” currencies. We quantify currency-induced balance sheet effects for total external positions as well as for individual asset classes using...

This paper analyzes the timing, pace and efficiency of the on- going job reallocation that results from product and process innovation. There are strong reasons why an efficient economy ought to concentrate both job creation and destruction during cyclical downturns, when the opportunity cost of...

Fluctuations in commodity prices are often associated with macroeconomic volatility. But not all nations are created equal in this regard. The macro response to commodity booms and busts depends both on the structural characteristics of the economy and on the policy framework that is in place....

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...
