In this paper, we study the statistical properties of heterogeneous agent models with incomplete markets. Using a Bewley-Hugget-Aiyagari model we compute the equilibrium density function of wealth and show how it can be used for likelihood inference. We investigate the identifiability of the...

We study the statistical properties of heterogeneous agent models. Using aBewley-Hugget-Aiyagari model we compute the density function of wealth and in-come and use it for likelihood inference. We study the finite sample properties of themaximum likelihood estimator (MLE) using Monte Carlo...

One of the problems faced by a firm that sells certain commodities is to determine the number of products that it must supply with in order to maximize profits. In this article, the authors give an answer to this problem of economic interest. To solve it they use the theorem of the "unconscious...

We used elements of the qualitative theory of differential equations, sometimes called “catastrophe theory”, to justify the distribution of income. Within the framework of the proposed model, the concept of “middle class” receives a strict, non-descriptive definition. According to the...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

This is a short survey on consumption theory. Consumption is important to both fluctuation and growth. In addition, consumption introduces some important issues involving financial markets and portfolio decisions. We will describe consumption decisions in a dynamic context. Uncertainty about...

This paper presents the bibliometrics of a Keynesian and neoclassical discussion about the multiplier-accelerator effect. Having its oldest roots in the 1930s, there was a special emphasis in the 1960s and 1970s on discussions regarding the dependence of current investment on economic growth...

In this paper we intend to present some theoretical approaches regarding measuring of the main determinants influence on inflation and based on these determinations to present the developments observed in the Romanian economy. Inflationary process is in the spotlight of all the world...
