Although wage rigidity is among the most prominent subjects in modern economics, its effects on wage compression and firm training have thus far not been considered. This paper is trying to bridge this gap by using a simple two period model which can still by analyzed analytically. I am able to...

We build quadratic labor adjustment costs into an otherwise standard New-Keynesian model of the business cycle and show that this is sufficient to increase both, output and inflation persistence.

In the presence of increasing specialization of workers it becomes more and more difficult for firms to find the most suitable workers. In such an environment a multinational corporation has an advantage because it can exchange workers between plants in different countries. In this way it can...

This paper investigates Samuelson's (JEP, 2004) argument that technical progress of the trade partner may hurt the home country. We illustrate this prospect in a simple Ricardian model for sitations with outward knowledge spillovers. Within this framework Samuelson's Act II effects may occur....

Models with heterogeneous interacting agents explain macro phenomena through interactions at the micro level. We propose genetic algorithms as a model for individual expectations to explain aggregate market phenomena. The model explains all stylized facts observed in aggregate price fluctuations...

This paper analyzes, within a regional growth model, the impact of productive governmental policy and integration on the spatial distribution of economic activity. Integration is understood as enhancing territorial cooperation between the regions, and it describes the extent to which one region...

We develop an endogenous growth model which is focussed on entrepreneurial skills and their impact on growth and convergence. Our work is closely related to the model by Acemoglu et al. (2006) but extends their analysis in some important respects. Entrepreneurs in our model dispose of two...

This paper analyzes a stylized model of international capital mobility and diffusion of embodied technologies from North to South. The South can fall behind in terms of technologies or get trapped in a situation, in which it is unable to attract foreign capital and embodied technologies, if its...

We examine the effect of exchange-rate misalignments on competition in the market for large commercial aircraft. This market is a duopoly where players compete in dollar-denominated prices while one of them, Airbus, incurs costs mostly in euros. We construct and calibrate a simulation model to...

We study the design of optimal monetary policy (Ramsey policies) in a model with sticky prices and unionized labour markets. Collective wage bargaining and unions monopoly power tend to dampen wage fluctuations and to amplify employment fluctuations relatively to a DNK model with walrasian...
