We compare risk sharing in response to demand and supply shocks in four types of currency unions: segmented markets; a banking union; a capital market union; and complete financial markets. We show that a banking union is efficient at sharing all domestic demand shocks (deleveraging, fiscal...

We present a dynamic quantitative trade and migration model that incorporates downward nominal wage rigidities and show how this framework can generate changes in unemployment and labor force participation that match those uncovered by the empirical literature studying the “China shock.” We...

Donald Trump's election and his nomination of Scott Pruitt, a climate skeptic, to lead the Environmental Protection Agency drastically downshifted expectations on US climate-change policy. We study firms' stock-price reactions and institutional investors' portfolio adjustments after these...

Because of the uncertainty about how to model the growth process of our economy, there is still much confusion about which discount rates should be used to evaluate actions having long-lasting impacts, as in the contexts of climate change, social security reforms or large public infrastructures...

This paper studies the state-dependence of the output and welfare effects of shocks to government purchases in a canonical medium scale DSGE model. When monetary policy is characterized by a Taylor rule, the output multiplier (the change in output for a one unit change in government spending) is...

We study numerically the inter- and intra-generational welfare consequences of alternative pension fund policies in response to unexpected demographic, financial and macro-economic shocks. Our analysis is based on an applied many-generation OLG model describing a small-open economy with...

A representative-consumer model with Epstein-Zin-Weil preferences and i.i.d. shocks, including rare disasters, accords with key asset-pricing observations. If the coefficient of relative risk aversion equals 3-4, the model accords with observed equity premia and risk-free real interest rates. If...

This paper studies monetary policy in a model where output fluctuations are caused by shocks to public beliefs on the economy's fundamentals. I ask whether monetary policy can offset the effect of these shocks and whether this offsetting is socially desirable. I consider an environment with...

In this paper we examine how target ranges work in the context of a Barro-Gordon (1983) type model, in which the time-inconsistency problem stems from political pressures from the government. We show that target ranges turn out to be an excellent way to cope with the time-inconsistency problem,...

We develop a five-region version (Canada, a group of oil exporting countries, the United States, emerging Asia and Japan plus the euro area) of the Global Economy Model (GEM) encompassing production and trade of crude oil, and use it to study the international transmission mechanism of shocks...
