In a standard two-sector neoclassical model with distortions, capital mobility can render the steady state indeterminate, in the sense that there exist infinitely many convergent paths. In the closed economy with no international capital mobility, the utility function must be linear or close to...

In this paper we discuss recent advances in modeling and estimating dynamic factor demand models, and review the use of such models in analyzing the production structure, the determinants of variable and quasi-fixed factors, and productivity growth. The paper also discusses the traditional...

Financial repression (FR) allows the government to save on its interest rate payments. However, forcing financial intermediaries to increase the share of government debt in their portfolios can alter transmission of macroeconomic shocks. In this paper, we raise the question whether it is the...

This paper discusses the consequences of introducing imperfectly competitive product markets into an otherwise standard neoclassical growth model. We pay particular attention to the consequences of imperfect competition for the explanation of fluctuations in aggregate economic activity. Market...

We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost in the domestic market and both fixed and per-unit export costs. Only...

The inefficiencies related to endogenous product creation and variety under monopolistic competition are two-fold: one static—the misalignment between consumers and producers regarding the value of a new variety; and one dynamic—time variation in markups. Quantitatively, the welfare costs of...

Which monetary regime is associated with the most stable price level? A commodity money regime such as the classical gold standard has long been associated with long-run price stability. But critics of the day argued that the regime was associated with too much short-run price variability and...

This paper analyzes the effects of nominal wage rigidity on inflation persistence and unemployment using a dynamic stochastic general equilibrium model for the Tunisian economy. The model is estimated by using the Bayesian approach for a small open economy, allowing to simultaneously introduce...
