This paper makes changes in monetary policy rules (or regimes) endogenous. Changes are triggered when certain endogenous variables cross specified thresholds. Rational expectations equilibria are examined in three models of threshold switching to illustrate that (i) expectations formation...

Is the exchange rate or the money growth rate the better instrument of monetary policy? A common argument is that the exchange rate has a natural advantage because it is more transparent: it is easier for the public to monitor than the money growth rate. We formalize this argument in a simple...

We consider positive and normative aspects of subsidizing work arrangements where subsidies are paid in time of low demand and reduced working hours so as to stabilize workers’ income. In a matching framework such an arrangement increases labor demand. Tightening eligibility to short-time work...

Major changes have taken place in the U.S. economy within the past quarter century. Changes with implications that are at least potentially important for the effect of monetary policy on real economic activity include the elimination of Regulation Q interest ceilings and the development of the...

This paper studies how gradualism affects the welfare gains from trade, technology, and reforms. When people face adjustment frictions, gradual shocks create less adverse distributional effects in the short run. We show that there are welfare gains from inducing a more gradual transition via...

Evaluating inflation-targeting monetary policy is more complicated than checking whether inflation has been on target, because inflation control is imperfect and flexible inflation targeting means that deviations from target may be deliberate in order to stabilize the real economy. A modified...

In contrast to earlier recessions, the monetary regimes of many small economies have not changed in the aftermath of the global financial crisis. This is due in part to the fact that many small economies continue to use hard exchange rate fixes, a reasonably durable regime. However, most of the...

The European Central Bank is unique in setting monetary policy for several sovereign states with heterogeneous debt levels and different maturity structures. The monetary-fiscal nexus is central to the functioning of the euro area. We focus on one particular aspect of that nexus, the effect the...

We analyze how expropriation risk reduces incentives for innovation and reallocates resources from the innovative sector, building on Romer's(1990) model. Our framework predicts the R&D expenditure, the share of human capital in R&D, the number of patents, technical progress, and economic growth...
