We consider models defined by a set of moment restrictions that may be subject to weak identification. More specifically, we study the asymptotic properties of the standard GMM estimator and the Hansen J-test when additional moment restrictions that are weaker than the original ones are...

The effectiveness of monetary policy depends, to a large extent, on market expectations of its future actions. In a standard New Keynesian business cycle model with rational expectations, systematic monetary policy reduces the variance of inflation and output gap by at least two-thirds. These...

Currently, we have only a limited understanding of how central bank purchases of illiquid assets (“quantitative easing”) affect long-term interest rates, borrowing costs, and the real economy. Since the historical record of quantitative easing is sparse, theoretical work is needed to guide...

Calibration results in Rabin (2000) and Safra and Segal (2008; 2009) suggest that both expected and non-expected utility theories cannot produce non-negligible risk aversion over small stakes without producing implausible risk aversion over large stakes. This paper provides calibration results for...

How does the allocation of scarce jobs and production influence their supply? We present the results of a macroeconomics laboratory experiment that investigates the effects of alternative rationing schemes on economic stability. Participants play the role of consumer-workers who interact in...

Can monetary or fiscal policy stabilize expectations in a liquidity trap? We study expectation formation near the zero lower bound using a learning-to-forecast laboratory experiment. Monetary policy targets inflation around a constant or state-dependent target. Subjects’ expectations...

In laboratory asset markets, subjects trade shares of a firm whose profits in a linked product market determine dividends. Treatments vary whether dividend information is revealed once per period or in real-time and whether the firm is controlled by a profit-maximizing robot or human subject....

This article describes experimental economics, in general, and new developments in experimental macroeconomics, in particular. The approach has a clear niche in providing evidence on economic phenomena that cannot be observed directly or that are difficult to measure. Experimental work conducted...

We explore the idea that prosocial behavior in experimental games is driven by social norms imported into the laboratory. Under this view, differences in behavior across subjects is driven by heterogeneity in sensitivity to social norms. We introduce an incentivized method of eliciting...
