This paper presents a macroeconomic model with some microfoundations for a small open economy. The main purpose is the simulation of external environment and fiscal policy shocks. The model includes sufficiently disaggregated public sector and household disposable income accounts and it...

According to the theory of efficient markets, economic agents use all available information to form rational expectations. Fiscal marksmanship, the accuracy of budgetary forecasting, can be one important piece of such information the rational agents must consider in forming expectations. Using...

This paper represents shortly the contribution of the Professor Lucas in modern macroeconomics, notably famous criticism of the Keynesian models. Contribution which was worth him the Nobel prize of economy 1995.

Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies. An open subset of...

Abstract: The partial information rational expectations solution to a general linear multivariate expectational macro-model is found when agents are uncertain about the true values of the model’s parameters. Necessary and sufficient conditions for convergence to the full information rational...

The rational expectations hypothesis for survey and model-based inflation forecasts − from the Survey of Professional Forecasters and the Greenbook respectively − is examined by properly taking into account the persistence characteristics of the data. The finding of near-unit-root effects in...

In this paper, we investigate the nature of rational expectations equilibria for economic epidemiological models. Unlike mathematical epidemiological models, economic epidemiological models can produce regions of indeterminacy or instability around the endemic steady state. We consider SI, SIS,...

This work intends to demonstrate the relevance and range of the contributions of Herbert A. Simon, as the pace of its ideas were useful as fundament to the development of many theoretical currents out of the mainstream. In this picture it will be highlighted, very briefly, examples in the...

We obtain a closed-form solution to rational expectations equilibrium with transaction costs in the framework of Grossman and Stiglitz (1980) [On the impossibility of informationally efficient markets. American Economic Review 70, 543-566]. Individual private information incorporated into prices...

This note presents a simple generalization of the adaptive expectations mechanism in which the learning parameter is time variant. It is shown that expectations generated in this way are rational in the sense of producing minimum mean squared forecast errors for a broad class of time series...
