The financial crisis raises demands for fiscal policy interventions. While a fall in aggregate demand is an important consequence of the crisis, it also reflects more underlying structural problems and changes. Hence, appropriate policy designs have to take account of the nature of the crisis...

We find that lottery tax windfalls finance higher state-government expenditures on supplemental security income that increase consumption, but only during bust periods. Wealth transfers from lottery winners to low income households enable fiscal policy to stabilize consumption during bust periods.

To what extent have national fiscal policies contributed to the decarbonisation of newly sold passenger cars? We construct a simple model that generates predictions regarding the effect of fiscal policies on average CO2 emissions of new cars, and then test the model empirically. Our empirical...

This paper studies the impact government expenditure has on inflation by examining an augmented Phillips curve implied from a structural New Keynesian model, Our estimation results, based on external instruments, show that the augmented Phillips curve has a flatter slope than the canonical...

I study how unsecured credit affects the extent to which unemployment insurance (UI) policies smooth cyclical fluctuations in aggregate consumption. To do so, I develop a real business cycle model with incomplete asset markets, frictional labor markets, and defaultable debt. Using empirically...

We present an incomplete markets model to understand the costs and benefits of increasing government debt when an increased demand for safety pushes the natural rate of interest below zero. A higher demand for safe assets causes the ZLB to bind, increasing unemployment. Higher government debt...

We compute average mark-ups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions the results, with annual data for a set of 14 OECD countries covering the period 1970-2007, show...

We show in a dynamic stochastic general equilibrium framework that the introduction of a common currency by a group of countries with only partially integrated goods markets, incomplete financial markets and no labor migration across member states, significantly increases volatility of...

Using panel data on military spending for 125 countries, we document new facts about the effects of changes in government purchases on the real exchange rate, consumption, and current accounts in both advanced and developing countries. While an increase in government purchases causes real...
