We study a model of endogenous growth where firms invest both in product and process innovations. Product innovations (that open up completely new product lines) satisfy the advanced wants of the rich. Subsequent process innovations (that decrease costs per unit of quality) transform the...

In this article, we demonstrate that a small degree of stochastic variation in the depreciation rate of capital can greatly reduce the comovement between hours worked and labor productivity in a neoclassical growth model. The depreciation rate is modeled as a Markov process to place a strict...

Monetary policy is often analysed in terms of simple rules. Such rules may be useful for many purposes, even when they do not describe the actual monetary policy strategy exactly. This paper compares monetary policy in Sweden during the inflation-targeting regime 19932002 with the policies...

This study extends the current New Keynesian modeling framework by changing one crucial aspect: it replaces the general equilibrium assumption by the arguably more realistic assumption of macroeconomic disequilibrium. As a result, more complex and less smooth macroeconomic adjustment dynamics...

In this paper, we explore the role of labor markets for monetary policy in the euro area in a New Keynesian model in which labor markets are characterized by search and matching frictions. We first investigate to which extent a more flexible labor market would alter the business cycle behavior...

We evaluate residual projection strategies in the context of a large-scale macro model of the euro area and smaller benchmark time-series models. The exercises attempt to measure the accuracy of model-based forecasts simulated both out-of-sample and in-sample. Both exercises incorporate...

In this paper, we explore the role of labor markets for monetary policy in the euro area in a New Keynesian model in which labor markets are characterized by search and matching frictions. We first investigate to which extent a more flexible labor market would alter the business cycle behaviour...

This paper evaluates simple, non-optimising monetary policy rules in the tradition of the well-known Poole analysis within a general two-country open-economy model of the New Open Economy Macroeconomic framework. Pure money supply rules are compared with simple interest rate rules for the large...

Rational expectations has been the dominant way to model expectations, but the literature has quickly moved to a more realistic assumption of boundedly rational learning where agents are assumed to use only a limited set of information to form their expectations. A standard assumption is that...

In the paper, some empirical results from a macroeconometric disequilibrium model for the Federal Republic of Germany are reported. In the theoretical model, a delayed adjustment of employment and investment is analyzed. Market disequilibrium is introduced by allowing for a sluggish adjustment...
