In this study I examine the welfare implications of monetary policy by constructing a novel New Keynesian model that properly accounts for asset pricing facts. I find that the Ramsey optimal monetary policy yields an inflation rate above 3.5% and inflation volatility close to 1.5%. The same...

We develop a business cycle model with gross flows of firm creation and destruction.The credit market is characterized by two frictions. First,entrepreneurs undergo a costly search for intermediate funding to create a firm. Second, upon a match, a costlystate-verification contract is set up....

Many decisions made by authorities pose uncertain consequences for the individuals affected by them, yet people must determine the extent to which they will support the change. Integrating the social justice and behavioral decision theory literatures, the article argues that individuals...

The study universally examines the consequences of geopolitical risk (GPR) on the financial stability of global banking systems with a large panel of 158 economies around the world over the past decades. We find the adverse effects of GPR on financial stability with the predicted (increase)...

This paper lays down the rudiments of a descriptive theory of competition among the digital tech platforms known as “FANGs” (Facebook, Amazon, Netflix and Google), amidst rising academic and policy polarization over the answer to what seems to be – at least at the formulation level – a...

We examine the effect of a threat of entry on experimentation about demand by an incumbent monopolist when there is a fixed cost of entry. We also examine the impact of experimentation on the probability of entry into the market. We show that experimentation may itself be used as a tool for...

Both consumers and a monopolist producer are uncertain about a good's quality. I derive conditions under which the value of public information about quality will be positive or negative to consumers and the firm. I find that the firm always prefers more information, but consumers may not. I...

In this article I analyze strategic investment under uncertainty in a new market, where firms face a tradeoff between commitment and flexibility. The model predicts asymmetric equilibria under fairly general conditions, even though firms are ex ante identical and have symmetric opportunities to...

This chapter studies how incomplete information helps accommodate frictions in coordination, leading to novel insights on the joint determination of expectations and macroeconomic outcomes. We review and synthesize recent work on global games, beauty contests, and their applications. We...
