First, the concept of public expenditure multiplier is redefined to allow for import intensity of exports, and its value is estimated for Poland and the Czech Republic in 2008-2009. Next, on the basis of effective demand model of economic dynamics, there follows a comparative analysis of GDP...

In this paper it, we have conducted a factor analysis which implied determining the international research directions that have characterized the period following the outbreak of the crisis in 2007 and 2008-2011. In this research, we used secondary data that were extracted from 342 articles,...

This paper introduces four different focuses for microeconomics and macroeconomics that are based on the uses of multidimensional graphical modeling and multidimensional mathematical modeling. The main objective of this paper is to present some classic economic theoretical approaches such as the...

Cities exist because of the productivity gains arising from clustering production and workers, a process called agglomeration. How important is agglomeration for aggregate growth? This paper constructs a dynamic stochastic general equilibrium model of cities and uses it to estimate the effect of...

This article critically evaluates the benefits and costs of the dominant methodology in macroeconomics, the DSGE approach. Although the approach has led to great progress in some areas, I argue that its conceptual restrictions, numerical methods, and the resulting complexity have created biases...

This paper proposes a theoretical framework of the Macroeconomic black holes. The idea is to observe “HOW” the macroeconomic black holes can generate less economic growth according to this paper. The same paper proposes the multi-dimensional graphical modeling and a basic mathematical...

The authors construct a dynamic general equilibrium model of cities and use it to estimate the effect of local agglomeration on per capita consumption growth. Agglomeration affects growth through the density of economic activity: higher production per unit of land raises local productivity....

I construct a unified macroeconomic framework by incorporating frictional markets in a neoclassical environment. This framework is analytically tractable despite search frictions, income risks and endogenous money distributions. I use this framework to formalize a theory that the variety and the...
