We argue that the role played by output-composition changes on the decline in US output volatility has been incorrectly assessed in the recent literature. We obtain that shifts across broad sectors in the economy account for about thirty-percent of the volatility decline since the 1950’s.

Here author made an attempt to extend the Continuous-Time Model of Business Fluctuations on the space domain. Research methodology is based on Time-Space Model of Wave Propagation developed by author to describe fluctuation processes in physics.

Presented here is the economical model with one commodity that is produced by two independent business entities. Investigated is the mutual impact of entities on each other, and formally described is the dynamics of competitive behavior. The research techniques and results are based on the...

The paper examines a new possibility of output gaps in an economy without any rigidity. The driving force behind the new possibility is non-cooperative behavior of consumers. The paper shows that there is a possibility that when a fundamental shock hits an economy this non- cooperative nature...

This paper presents a more realistic endogenous time preference model, incorporating the property that impatience decreases as consumption increases. The model overcomes a serious drawback of the existing model, which needs the assumption of increasing impatience. The new model is applied to the...

Uncertainty represented by volatilities in equity markets has been observed to be time-variable and lead output fluctuations. In the rational expectation framework, uncertainty with this nature needs exogenous variables with time-varying volatilities, but technology, tastes and fiscal and...

The paper deals with the application of Minimum Weighted Residual Methods (MWR) in intertemporal optimizing models of endogenous economic growth. In the 1st part of the paper the basics of the MWR method are described. Attention is mainly concentrated on one special class of MWR methods: the...

This paper investigates the effect of sovereign risk on the stochastic rational expectations equilibrium of a real business cycle small open economy. The credit market is imperfect because the sovereign cannot commit to repay its outstanding debt and chooses to default when it is optimal to do...

By simplifying the computational tasks and by providing step-by-step explanations of the procedures required to study a linear dynamic rational expectations (LDRE) model, this paper and the accompanying ``LDRE Toolbox' of Matalb functions guide a researcher with almost no experience in...

This paper extends the standard Real Business Cycle model to incorporate sectoral shifts in unemployment. Using relative sectoral technology and sectoral tastes shocks, combined with labor adjustment costs across sectors, we assess the possibility of generating persistent aggregate unemployment....
