This paper theoretically and empirically documents a puzzle that arises when an RBC economy with a job matching function is used to model unemployment. The standard model can generate sufficiently large cyclical fluctuations in unemployment, or a sufficiently small response of unemployment to...

This paper presents a hidden Markov model of credit quality dynamics, and highlights the use of filtering-based estimation methods for models of this kind. We suppose that the Markov chain governing the 'true' credit quality evolution is hidden in 'noisy' or incomplete observations represented...

The price stabilization problem is stated and solved for a nonlinear cobweb model with government stocks. It is shown that if the storage capacity for the commodity is sufficiently large then there exists a simple stabilization policy, called the 'keep supply at equilibrium (KSE)' policy, such...

In this paper we study an endogenous growth model, in which public maintenance expenditures affect the depreciation rate of public capital and the latter is subject to congestion. We find that economies with low congestion in public infrastructure will require a threshold level of public capital...

In a monetary union, inflation rate differentials may be substantial over the business cycle. This paper parameterizes a monetary union with cross-country structural differences in (i) the elasticity of demand in the goods markets, (ii) the degree of price inertia and (iii) the preference for...

The central variable of theories of financial frictions--the external finance premium--is unobservable. This paper distils the external finance premium from a Dynamic Stochastic General Equilibrium (DSGE) model estimated on US macroeconomic data covering the period 1954 to 2004. Within the DSGE...

Some economic models like the cash-in-advance model of money or overlapping generations model have the property that the dynamical system characterizing equilibria in the model are multi-valued going forward in time, but single-valued going backward in time, i.e., the model or dynamical system...

This paper models the scale of the technology shocks as a decision variable whose value is determined by the production manager. It is shown that smaller shocks enhance profit in several ways and thus the firm has an incentive to adopt more reliable production technologies. The adoption of these...
