We present evidence that noisy financial flows influence financial conditions and macroeconomic activity. How should monetary policy respond to this noise? We develop a model where it is optimal for the central bank to target and (partially) stabilize financial conditions beyond their direct...

Capitalism since its inception has been marked by large fluctuations. The resulting episodic unemployment has been very costly. This paper provides an overview of alternative theories. Standard models (such as DSGE) have not provided insights into the causes of the fluctuations and the shocks...

In line with Keynes' intuition, volatility in the stock market and in real economic activity are linked by expectations of long term profits. We show that analysts' optimism about the long term earnings growth of S&P 500 firms is associated with a near term boom in major US financial markets,...

We propose a model where monetary policy is the key determinant of aggregate asset prices (financial conditions). Spending decisions are made by a group of agents ("households") that respond to aggregate asset prices, but with noise, delays, and inertia. Asset pricing is determined by a...

Are unregulated capital flows excessive during a stagflation episode? We argue that they likely are, owing to a macroeconomic externality operating through the economy's supply side. Inflows raise domestic wages through a wealth effect on labor supply and cause unwelcome upward pressure on...

We find that procyclical stocks, whose returns comove with business cycles, earn higher average returns than countercyclical stocks. We use almost a three-quarter century of real GDP growth expectations from economists' surveys to determine forecasted economic states. This approach largely...
