The paper treats the theory of short-term costs and long-term costs from an axiomatic perspective.

Based on the four major types of economic cycles (Kondratieff, Juglar, Kitchin, Kuznet), the paper aims to determine their actual length (for the U.S. economy) using cyclic regressions based on Fourier analysis.

The paper treats a problem of a great importance in the author's view relatively to the behavior of polynomial regressions to linear transformations of the variables. If, from a theoretical point of view, the estimation of a process using regressions give the same results, regardless of the size...

The article deals with a production function of three factors with constant scale return where each elasticity of two of the factors is a function of first degree. After the examination of parameters conditions according to the axioms of the production functions, there are computed the main...

In this paper, we have investigated the dependence of taxes based on GDP in Romania during 2001-2011. After determining the regression equation, an apparently surprising conclusion is that there is a weak dependence of tax revenues to the GDP.

In the actual economic crisis, the financial market and the balance of trade of Romania are sensible chapters of the economic policy. The paper analyses some aspects of the financial market and also the trends of exports and imports between Romania and the major partners, on global and also on...

The Electre method aims as objective the choosing of the best variant in the conditions of existence of some decision criteria. An interesting problem arises when different variants associated to the values ??are not constant but are in intervals. The paper treats how to determine the optimal...

In this paper, we have investigated the dependence of money demand based on GDP and the real interest rate in Romania during 2001-2011. After determining the regression equation, an apparently surprising conclusion is that the most influential factor in the demand for money is the level of GDP...

In this paper, we first study the static equilibrium of a a closed economy model in terms of dependence on national income and interest rate from the main factors namely the marginal propensity to consume, tax rate, investment rate and the rate of currency demand. In the second part, we study...

In the actual economical crisis, the balance of trade of Romania is a sensible chapter of the economical policy. The paper analyses the trends of exports and imports between Romania and the major partners, on global and also on groups of goods arriving at the conclusion that if Romania was on a...
