In a Ramsey policy regime, heterogeneity in beliefs about the potential costs of climate change is shown to produce policy ambiguities that alter carbon prices and taxation. Three sources of ambiguity are considered: (i) the private sector is skeptical, with beliefs that are unknown to the...

Intertemporal general-equilibrium models with Keynesian features such as imperfect competition and imperfectly flexible prices which give rise to a (at least) short-run non-neutrality of monetary policy have become the workhorse model for monetary macroeconomics. This thesis now makes four...

This paper develops a two-country DSGE model for a monetary union in which each country is populated by two types of households - savers and borrowers - and two types of production sectors - a consumption goods sector and a housing sector. Households trade nominal private debt in equilibrium,...

We develop a multisector model in which capital and labor are free to move across firms within each sector, but cannot move across sectors. To isolate the role of sectoral specificity, we compare our model with otherwise identical multisector economies with either economy-wide or firm-specific...

Low-skilled workers are concentrated in sectors that experience fast productivity growth and yet their real wages have been stagnating. We document evidence from the U.S. to show the importance of sectoral reallocations. Key to our two-sector model is the fall in the relative price of the...
