The estimated persistence of macro aggregates involving lumpy microeconomic adjustment is biased downward when inferred from VAR estimates. The extent of this “missing persistence bias” decreases with the level of aggregation, yet convergence is very slow. Paradoxically, while idiosyncratic...

This paper develops a model with multiple steady states (low tax and low unemployment versus high tax and high unemployment) in which equilibrium selection is not conditioned on a sunspot variable. Instead, large temporary shocks initiate unavoidable transitions from one steady state to another....

This paper surveys the transmission mechanisms of monetary policy beyond the standard interest rate channel by focusing on how monetary policy affects the economy through other asset prices. It outlines how the monetary transmission mechanisms operating through stock prices, real estate prices,...

The increasing returns revolution in trade is incomplete in an important respect there exists no compelling empirical demonstration of the role of increasing returns in determining production and trade structure. One reason is that trade patterns of the canonical increasing returns models are a...

How should the issue of domestic labor standards be handled in the GATT/ WTO? This question is part of a broader debate over the appropriate scope of international economic institutions such as the GATT, where member-countries are considering proposals for a new round of n3 negotiations that...

This paper examines the suggestion that established plaintiffs request preliminary injunctions to engage in predation against less financially healthy firms. We first present a model in which differences in litigation costs drive the use of preliminary injunctions in civil litigation. The...

A developing country often pegs its exchange rate to a single currency, such as the U.S. dollar, even though it faces a higher inflation rate than the country to which it is pegged. As a consequence, it experiences real exchange-rate misalignments and a series of easily-anticipated devaluations....

This paper proposes a framework which integrates convex costs of adjustment and expectations formation in the determination of investment decisions in R&D at the firm level. The model is based on cost minimization subject to the firm's expectations of the stream of output and the price of R&D,...
