Working Paper
Doves for the Rich, Hawks for the Poor? Distributional Consequences of Monetary Policy
We build a New Keynesian business-cycle model with rich household heterogeneity. A central feature is that matching frictions render labor-market risk countercyclical and endogenous to monetary policy. Our main result is that a majority of households prefer substantial stabilization of unemployment even if this means deviations from price stability. A monetary policy focused on unemployment stabilization helps Main Street" by providing consumption insurance. It hurts Wall Street" by reducing precautionary saving and, thus, asset prices. On the aggregate level, household heterogeneity changes the transmission of monetary policy to consumption, but hardly to GDP. Central to this result is allowing for self-insurance and aggregate investment.

Working Paper
Global Spillovers of a China Hard Landing
China?s economy has become larger and more interconnected with the rest of the world, thus raising the possibility that acute financial stress in China may lead to global financial instability. This paper analyzes the potential spillovers of such an event to the rest of the world with three methodologies: a VAR, an event study, and a DSGE model. We find the sentiment channel to be the primary spillover channel to the United States, affecting global risk aversion and asset prices such as equity prices and the dollar, in addition to modest real effects through the trade channel. In comparison, the combined financial and real effects to other advanced and emerging market economies, especially net commodity exporters, would be more consequential due to their larger direct exposure to China and more limited scope of monetary policy to respond to shocks.

Working Paper
Monetary policy with heterogeneous agents
We build a New Keynesian model in which heterogeneous workers differ with regard to their employment status due to search and matching frictions in the labor market, their potential labor income, and their amount of savings. We use this laboratory to quantitatively assess who stands to win or lose from unanticipated monetary accommodation and who benefits most from systematic monetary stabilization policy. We find substantial redistribution effects of monetary policy shocks; a contractionary monetary policy shock increases income and welfare of the wealthiest 5 percent, while the remaining 95 percent experience lower income and welfare. Consequently, the negative effect of a contractionary monetary policy shock to social welfare is larger if heterogeneity is taken into account.

Working Paper
Risk, economic growth and the value of U.S. corporations
This paper documents a strong association between total factor productivity (TFP) growth and the value of U.S. corporations (measured as the value of equities and net debt for the U.S. corporate sector) throughout the postwar period. Persistent fluctuations in the first two moments of TFP growth predict two-thirds of the medium-term variation in the value of U.S. corporations relative to gross domestic product (hence-forth value-output ratio). An increase in the conditional mean of TFP growth by1% is associated to a 21% increase in the value-output ratio, while this indicator declines by 12% following a 1% increase in the standard deviation of TFP growth. A possible explanation for these findings is that movements in the first two moments of aggregate productivity affect the expectations that investors have regarding future corporate payouts as well as their perceived risk. We develop a dynamic stochastic general equilibrium model with the aim of verifying how sensible this interpretation is. The model features recursive preferences for the households, Markov-Switching regimes in the first two moments of TFP growth, incomplete information and monopolistic rents. Under a plausible calibration and including all these features, the model can account for a sizable fraction of the elasticity of the value-output ratio to the first two moments of TFP growth.
