Understanding booms and busts in housing markets
Some booms in housing prices are followed by busts. Others are not. In either case it is difficult to find observable fundamentals that are correlated with price movements. We develop a model consistent with these observations. Real estate agents have heterogeneous expectations about long-run fundamentals but change their views because of "social dynamics." Agents meet randomly with one another. Those with tighter priors are more likely to convert others to their beliefs. The model generates a "fad": The fraction of the population with a particular view rises and then falls. Depending on ...

When is the government spending multiplier large?
We argue that the government spending multiplier can be very large when the nominal interest rate is constant. We focus on a natural case in which the interest rate is constant, which is when the zero lower bound on nominal interest rates binds. For the economies that we consider it is optimal to increase government spending in response to shocks that make the zero bound binding.

Nominal rigidities and the dynamic effects of a shock to monetary policy
The authors? model, embodying moderate amounts of nominal rigidities, accounts for the observed inertia in inflation and persistence in output. The key features of their model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these features, the most important are staggered wage contracts of average duration (three quarters) and variable capital utilization.

Firm-specific capital, nominal rigidities, and the business cycle
Macroeconomic and microeconomic data paint conflicting pictures of price behavior. Macroeconomic data suggest that inflation is inertial. Microeconomic data indicate that firms change prices frequently. We formulate and estimate a model which resolves this apparent micro - macro conflict. Our model is consistent with post-war U.S. evidence on inflation inertia even though firms re-optimize prices on average once every 1.5 quarters. The key feature of our model is that capital is firm-specific and predetermined within a period.

Expectations, traps and discretion
We argue that discretionary monetary policy exposes the economy to welfare-decreasing instability. It does so by creating the potential for private expectations about the response of monetary policy to exogenous shocks to be self-fulfilling. Among the many equilibria that are possible, some have good welfare properties. But, others exhibit welfare decreasing volatility in output and employment. We refer to the latter type of equilibria as expectation traps. In effect, our paper presents a new argument for commitment in monetary policy because commitment eliminates these bad equilibria. ...
