Se estima el componente de largo plazo de la tasa de desempleo en Colombia para los últimos veinte años. De acuerdo con los resultados, los principales determinantes del componente permanente de la tasa de desempleo son el salario real por hora, los costos laborales no salariales y la tasa de...

The colombian urban unemployment rate grew dramatically over the last six years. At the same time the real wage also had a sharp increase: The empirical evidence supports the hypothesis that an exogenous increase in the real wage was a cause of the unemployment growth. The long-run elasticity...

The dynamic general equilibrium model with hiring costs presented in this paper delivers involuntary unemployment in the steady state as well as involuntary fluctuations in unemployment. The existence of hiring friction introduces externalities that, in turn, entail the breakdown of the "divine...

In this paper we analyze a general equilibrium dynamic stochastic New Keynesian model characterized by labor indivisibilities, unemployment and a unionized labor market. The presence of monopoly unions introduces real wage rigidities in the model. We show that as in Blanchard Galì (2005) the so...

This paper analyses the influence of norms of fairness on wage formation. Fairness is defined by `real-wage' and `relative-wage' norms that relate wage offers to workers' own current wage and to the wages of other groups of workers, and, to avoid shirking, firms pay fair wages. The wage norms...

This paper presents a sequential model suited to analyze transitions between equilibria. Disequilibrium dynamics are obtained from a standard monopolistic competition model, by introducing a sequential structure and reasonable hypotheses about technology, finance constraints, expectation...

We combine micro and macro unemployment duration data to study the effects of the business cycle on the outflow from unemployment. We allow the cycle to affect individual exit probabilities of unemployed workers as well as the composition of the total inflow into unemployment. We estimate the...

We argue in favour of the shareholder model of the firm for three main reasons. First, serving multiple stakeholders leads to ill-defined property rights. What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle between the stakeholders about the ultimate...
