At the aggregate level, the evidence that deviations from purchasing power parity (PPP) are too persistent to be explained solely by nominal rigidities has long been a puzzle (Rogoff, 1996). Another puzzle from the micro price evidence of the law of one price (LOP), which is the basic building...

The current account in developed countries is highly persistent and volatile in comparison to their output growth. The standard intertemporal current account model with rational expectations (RE) fails to explain the observed current account and consumption dynamics. The RE model extended with...

Since the 2000s, large fluctuations in commodity prices have become a concern among policymakers regarding price stability. This paper investigates the effects of commodity price shocks on headline inflation with a monthly panel consisting of 144 countries. We find that the effects of commodity...

Previous studies argue that, based on the New Keynesian framework, a fiscal stimulus financed by money creation has a strong positive effect on output under a reasonable degree of nominal price rigidities. This paper investigates the effects of an implementation lag in a money-financed fiscal...

We examine the role of bank leverage to explain why the 2007-08 financial crisis unfolded at a time when the economy appears to be less fragile to crisis risks. To this end, we extend the model introduced by Diamond and Rajan (2012) to a variant where the probability of financial crises varies...

A fast growing literature on small open economy models with pecuniary externalities has provided the theoretical grounds for the policy analysis of macro prudential regulations. Using the framework of Jeanne and Korinek (2010), we investigate whether a subsidy on debt during crises as a form of...

We extend the Cole and Obstfeld model in a number of directions to more accurately assess the terms of trade channel. Two crucial theoretical extensions are: to allow multiple producers of each primary commodity and to allow for incomplete specialization.We find that the negative correlation...

State and local governments throughout the United States attempted to mitigate the spread of Covid-19 using stay-at-home orders to limit social interactions and mobility. We study the economic impact of these orders and their optimal implementation in a fiscal union. Using an event study...

In this paper, we argue that differences in the cost structure across sectors play an important role in the decision of firms to adjust their prices. We develop a menu-cost model of pricing in which retail firms intermediate trade between producers and consumers. An important facet of our...

Economic research into the causes of business cycles in small open economies is almost always undertaken using a partial equilibrium model. This approach is characterized by two key assumptions. The first is that the world interest rate is unaffected by economic developments in the small open...
