This paper presents a model where agents decide on the timing of replacement of ageing machines. The optimal replacement policy for an agent is influenced by other agents' decisions because the productivity of a particular vintage displays network externalities that set in with a lag. In...

In this paper, we provide a dynamic general equilibrium framework with an explicit investment-financing constraint. The constraint is intended as a reduced form to capture the balance sheet effects that have been widely regarded as an important determinant of financial crises. We derive a link...

El presente documento realiza un análisis del negocio del Gas Natural en Bolivia y de sus posibles impactos en las recaudaciones, exportaciones y el Producto Interno Bruto. Las principales conclusiones sugieren que, el sector de hidrocarburos se perfila como uno de los pilares para el...

Potential output figures are important ingredients of many macroeconomic modelsand are routinely applied by policy makers and global agencies. Despite itswidespread use, estimation of potential output is at best uncertain and dependsheavily on the model. The task of estimating potential output...

We assess the correlation of supply and demand shocks between current countries in the euro area and EU accession candidates from 1993/1995 to 2002. Supply and demand shocks are recovered from estimated structural VAR models of output growth and inflation. Notably, the economic slowdown between...

This paper investigates the dynamics of output, employment and prices in an economy with costs of adjusting labor and prices. In an economy with non convex adjustments costs, firms do not adjust labor and prices continuously to accommodate every shift in demand. Rather, firms adjust employment...

064Taylor's model of staggered contracts is an influential explanation for nominal inertia and the persistent real effects of nominal shocks. However, in standard imperfect competition models, if agents are allowed to choose the timing of pricing decisions, they will typically choose to...

This paper investigates whether monetary policy has asymmetric effects on stock returns using Markov-switching models. Different measures of the stance of monetary policy are adopted. Empirical evidence from monthly returns on the standard & Poor 500 (S&P 500) price index suggests that monetary...

This paper is a follow-on to our earlier paper, "Bifurcations in Continuous-Time Macroeconomic Systems." In this paper, we determine the stability properties of the UK continuous time macroeconometric model on its bifurcation boundaries and we test the null hypothesis that the model's parameters...

Much research on the dynamics of the aggregate economy concerns the adjustment policy of the microeconomic units. This paper investigates the optimal adjustment policy when there are seasonal fluctuations and fixed adjustment costs. The optimal policy in this case can be described in terms of...
