We develop a behavioral macroeconomic model in which agents use simple but biased rules to forecast future output and inflation. This model generates endogenous waves of optimism and pessimism (Animal Spirits") that are generated by the correlation of biased beliefs. We contrast the dynamics of...

This paper presents a new solution method for dynamic equilibrium models. The proposed method approximates the solution by polynomials that zero the residual function and its derivatives at a given point x0. It is essentially a projection-type algorithm, but is significantly faster than standard...

This paper analysis the welfare changes arising from a road project, undertaken as a public-private partnership, measured as the variation in utility, using a sequentially dynamic general equilibrium model. To circumvent the budget restriction imposed by the central government, the Azorean...

A dynamic general equilibrium two-country optimizing model is used to analyze the welfare effects of monetary policy in open economies. The distinguishing feature of the model is that households' preferences feature a "keeping up with the Joneses" effect. This effect implies that households'...

National and multinational companies coexist in many sectors of all developed countries. However, economic models fail to reproduce this fact because of the assumption of symmetry between companies. To show that the symmetry assumption is the reason for this failure, a two-country general...
