In the financial accelerator literature pioneered by Bernanke, Gertler and Gilchrist (1999) entrepreneurs are myopic and loans have a fixed rate of return by assumption. We relax both of these assumptions and derive the optimal lending contract for forward looking entrepreneurs who can choose a...

It is commonly assumed that binding collateral constraints amplify the impact of aggregate shocks on the economy. However, we show that when firms can hedge against aggregate risk with state-contingent lending contracts, binding collateral constraints no longer amplify shocks relative to the...

We study the conduct of monetary policy in a continuum of small open economies and obtain a novel closed-form solution that does not restrict the elasticity of substitution between home and foreign goods to one. We give an exact characterization of optimal monetary policy and welfare with and...

We establish the share of exports in production as a sufficient statistic for optimal non-cooperative monetary policy. Under financial autarky, markups positively co-move with the export share. For complete markets, markups should be procyclical if the export share is procyclical. When central...
