In recent years, central banks have increasingly turned to "forward guidance" as a central tool of monetary policy, especially as interest rates around the world have hit the zero lower bound. Standard monetary models imply that far future forward guidance is extremely powerful: promises about...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business in this set-up, we show that,...

In the data, wealth is very unequally distributed, even more so than labor earnings and income, and the saving rate of wealthy people is high. Many dynamic models used for quantitative policy evaluation imply that once households get rich, they dissave. As a result, these models generate too...

Government spending at the zero lower bound (ZLB) is not necessarily welfare enhancing, even when its output multiplier is large. We illustrate this point in the context of a standard New Keynesian model. In that model, when government spending provides direct utility to the household, its...

Why do people save? A strand of the literature has emphasized the role of ‘precautionary’ motives; i.e., private agents save in order to mitigate unexpected future income shocks. An implication is that in countries faced with more macroeconomic volatility and risk, private saving should be...

Households hold vastly heterogenous amounts of wealth when they reach retirement, and differences in lifetime earnings explain only part of this variation. This paper studies the role of intergenerational transmission of ability, voluntary bequest motives, and the recipiency of accidental and...
