The combination of a fixed exchange rate and downward nominal wage rigidity creates a real rigidity. In turn, this real rigidity makes the economy prone to involuntary unemployment during external crises. This paper presents a graphical analysis of alternative policy strategies aimed at...

Since the onset of the great recession in peripheral Europe, nominal hourly wages have not fallen much from the high levels they had reached during the boom years in spite of widespread increases in unemployment. This observation evokes a well-known narrative in which nominal downward wage...

This paper shows that in a small open economy model with downward nominal wage rigidity pegging the nominal exchange rate creates a negative pecuniary externality. This peg-induced externality is shown to cause unemployment, overborrowing, and depressed levels of consumption. The paper...

This paper introduces deep habits into a sticky-price sticky-wage economy and asks whether the countercyclical markup movements induced by deep habits is helpful for accounting for the dynamic effects of monetary policy shocks. We find that this is the case: When allowing for deep habits, the...

Since John Taylor's (1993) seminal paper, a large literature has argued that active interest rate feedback rules, that is, rules that respond to increases in inflation with a more than one-for-one increase in the nominal interest rate, are stabilizing. In this paper, we argue that once the zero...

This paper identifies a new source of business-cycle fluctuations. Namely, a common stochastic trend in neutral and investment-specific productivity. We document that in U.S. postwar quarterly data total factor productivity (TFP) and the relative price of investment are cointegrated. We show...

Observed inflation targets around the industrial world are concentrated at two percent per year. This paper investigates the extent to which the observed magnitudes of inflation targets are consistent with the optimal rate of inflation predicted by leading theories of monetary non-neutrality. We...

In this paper, we characterize conditions under which interest rate feedback rules that set the nominal interest rate as an increasing function of the inflation rate induce aggregate instability by generating multiple equilibria. We show that these conditions depend not only on the...

A key result of a recent literature that focuses on the global consequences of Taylor-type interest rate feedback rules is that such rules, in combination with the zero-bound on nominal interest rates, can lead to unintended liquidity traps. An immediate question posed by this result is whether...

Once the zero-bound on nominal interest rates is taken into account, Taylor-type interest-rate feedback rules give rise to unintended self-fulfilling decelerating inflation paths and aggregate fluctuations driven by arbitrary revisions in expectations. These undesirable equilibria exhibit the...
