We study optimal policy when the planner has partial information in a general setup where observed signals are endogenous to policy. In this context, signal extraction and policy have to be determined jointly. We derive a general non-standard first order condition of optimality from first...

High uncertainty is an inherent implication of the zero lower bound, while deflation is not because of inflationary pressure due to uncertainty about how debt will be stabilized. We show that policy uncertainty empirically accounts for the absence of deflation in the US economy. Announcing...

We reinterpret post World War II US economic history using an estimated microfounded model that allows for changes in the monetary/fiscal policy mix. We find that the fiscal authority was the leading authority in the ‘60s and the ‘70s. The appointment of Volcker marked a change in the...

We develop a theoretical framework to account for the observed instability of the link between inflation and fiscal imbalances across time and countries. Current policy makers behavior influences agents ' beliefs about the way debt will be stabilized. The standard policy mix consists of a...

This paper analyzes the importance of monetary and fiscal policy shocks in explaining US macroeconomic fluctuations, and establishes new stylized facts. The novelty of our empirical analysis is that we jointly consider both monetary and fiscal policy, whereas the existing literature only focuses...

Corporate governance distortions delay or even halt a country's transformation into a modern innovation economy. We investigate the mechanism through a growth model that allows for agency issues within firms. Governance distortions raise the cost of investment and depress the incentives to set...

We study the impact of corporate governance frictions in an economy where growth is driven both by the foundation of new firms and by the in-house investment of incumbent firms. Firms' managers engage in tunneling and empire building activities. Active shareholders monitor managers, but can...

In media markets, consumers spread their attention to several outlets, increasingly so as consumption migrates online. The traditional framework for studying competition among media outlets rules out this behavior by assumption. We propose a new model that allows consumers to choose multiple...

This paper examines racial and ethnic differences in high cost mortgage lending in seven diverse metropolitan areas from 2004-2007. Even after controlling for credit score and other key risk factors, African-American and Hispanic home buyers are 105 and 78 percent more likely to have high cost...
