While innovation is argued to create value, private incentives of firms to innovate are driven by what part of the value created firms can appropriate. In this paper we explore the relation between innovation and the markups a firm is able to extract after innovating. We estimate firm-specific...

Do locational fundamentals such as coastlines and rivers determine town locations, or can historical events trap towns in unfavorable locations for centuries? We examine the effects on town locations of the collapse of the Western Roman Empire, which temporarily ended urbanization in Britain,...

We develop a stylized EU-type model of a union consisting of rich, capital-abundant and productive, countries, and poor,capital-scarce and low productivity, countries, in order to explain key features of tax policies and inter- and intra-migration flows. Our purpose is to explain the differences...

With only minimal restrictions on security payoffs and trader preferences, noisy aggregation of heterogeneous information drives a systematic wedge between the impact of fundamentals on the price of a security, and the corresponding impact on cash flow expectations. From an ex ante perspective,...

This paper provides instrumental variables estimates of the response of aggregate private consumption to transitory output shocks in poor countries. To identify exogenous, unanticipated, idiosyncratic and transitory variations in national output we use year-to-year variations in rainfall as an...

We present a static model of aggregate demand and unemployment. The economy has a nonproduced good, a produced good, and labor. Product and labor markets have matching frictions. A general equilibrium is a set of prices, market tightnesses, and quantities such that buyers and sellers optimize...

How far can the media undermine democratic institutions, and how persuasive can media be in ensuring public support for a dictator’s policies? We study this question in the context of Germany between 1929 and 1939. Using quasi-random geographical variation in radio availability, we show that...

Consumers purchase multiple types of goods and services, but may be able to examine only a limited number of markets for the best price. We propose a simple model which captures these features, conveying some new insights. A firm's price can deflect or draw attention to its market, and...

The paper is a narrative on monetary policy and the banking sector during the two recent euro area recessions. It shows that while in the two episodes of recession and financial stress the ECB acted aggressively providing liquidity to banks, the second recession, unlike the first, has been...
