We develop a utility based model of fluctuations, with nominal rigidities, and unemployment. In doing so, we combine two strands of research: the New Keynesian model with its focus on nominal rigidities, and the Diamond-Mortensen-Pissarides model, with its focus on labor market frictions and...

This paper characterizes long-run and short-run optimal fiscal policy in the labor selection framework. In a calibrated non-Ramsey decentralized equilibrium, labor market volatility is inefficient. Keeping fixed the structural parameters, the Ramsey government achieves efficient labor market...

This paper extends the efficiency wages/partially adaptive expectations Phillips curve, otherwise known as the price-price Phillips curve, from a closed economy context to an open economy one with both commodity trade and capital mobility. We also consider the case of a monetary union (a...

We present a new partial equilibrium theory of price adjustment, based on consumer loss aversion. In line with prospect theory, the consumers' perceived utility losses from price increases are weighted more heavily than the perceived utility gains from price decreases of equal magnitude. Price...

The paper studies the effects of credible disinflation in the presence of real wage rigidity, comparing the Calvo and Rotemberg price setting mechanisms (the two popular variants of the New-Keynesian model). In both types of models, a credible, gradual disinflation is shown to lead to a delayed...

In the second part of the 80s, Japan was under political pressure to expand aggregate demand. It followed suit in increasing its money supply. This caused severe inflation and the financial bubble which collapsed in 1990 resulting in capital losses and in a sizable loss of GDP. This paper draws...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables.

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.

This paper attempts to evaluate the information content of money for the forecast of inflation, output, investment and consumption in the euro zone. It considers M1 and M3; a number of modifications to these aggregates is also proposed to enhance their forecast performance. The evaluation employs...

The paper extends the efficiency wages Phillips curve from a closed economy context to an open economy one with both commodity trade and capital mobility. Opening the trade account does not alter the slope of the Phillips curve, but it makes its position a function of the change of foreign and...
