We study the aggregate effects of sectoral productivity shocks in a multisectoral New Keynesian open-economy model that allows for asymmetric input-output linkages, both within and between countries, as well as for heterogeneity in sectoral Calvo-type price stickiness. Asymmetries in the...

We document empirical regularities of disaggregated inflation and consumption and study whether multisectoral New Keynesian models can explain them. We focus on higher moments of the inflation and consumption growth distributions as well as on the contemporaneous comovement of these two...

In macroeconomic models, the level of price dispersion - which is typically approximated through its relationship with inflation - is a central determinant of welfare, the cost of business cycles, the optimal rate of inflation, and the tradeoff between inflation and output stability. While the...

This paper shows that a simple form of nonlinearity in the Phillips curve can explain why, following the Great Recession, inflation did not decrease as much as predicted by linear Phillips curves, a phenomenon known as the missing disinflation. We estimate a piecewise-linear specification and...

Using novel data on military spending for 129 countries in the period 1988-2013, this paper provides new evidence on the effects of government spending on output in advanced and developing countries. Identifying government-spending shocks with an exogenous variation in military spending, we...

Using 25 years of military spending data from more than a hundred countries, this paper provides new evidence on the effect of government spending on output. Following a popular assumption that military spending is unlikely to respond to output at business-cycle frequencies - and exploiting...
