Even if there is a real need of a set of key performance indicators for small and medium sized enterprises, this is not yet considered to be satisfied. Our research is focused on two main aspects, each of them individually important for the users of accounting information: the basic indicators...

The more and more specialized equipments, developed in the last time with applicability in medicine, the necessary of materials more and more increased, determine the need of a good flow of activities in the field of the logistic of supply-chain management). These premises determine the...

The health systems consume a lot of resources. In the last thirty years, there was registered a continuous increase of the necessary resources’ level. This increase was mainly due to: the ageing of the population, discovery of more efficient medicines and of more advanced and costly...

We discuss the application of a new test for nonlinearity for economic time series. We apply the test for several monthly unemployment series from the developed economies. We find nonlinearities in the unemployment for most of the European economies, but not for US, UK or Japan.

The multifractal spectrum of a time series can be ascertained with a number of techniques, some based on wavelets, others based on the much newer (multifractal) detrended fluctuation analysis (MF-DFA). We test for the presence of multifractality in daily data on selected exchange rates from...

In this paper we discuss the credit policy and how it affected the macroeconomic dynamics in Romania. We estimate a regression on quarterly data in which economic growth is the dependant variable and foreign direct investments and domestic credit are the explanatory variable. We found...

I use the Bayesian approach in order to derive an estimation of Okun coefficient for Romania. The data used is at quarterly frequency and it consists in the unemployment rate and GDP between 2000 and 2009. I use three different priors, a normal one, a beta prior and a uniform prior for the...

It is well-known that economic and financial time series are characterized by nonlinearities. The literature does not agree, however, on the actual causes of such nonlinearities. In this paper, I investigate whether dynamics at different frequencies present different degree of nonlinearity, and...

I compare the two alternative paradigms of business cycles for the case of the Romanian economy, namely the mainstream view that business cycles are driven by stochastic shocks and the nonlinear view, known as the endogenous business cycles theory, which states that business cycles are driven by...

The monthly data of the industrial production in Romania after the structural discontinuity occurring at the end of 1989 show an under-damped oscillatory behavior that suggests an evolution of second order systems excited by a step function. Since this behavior is well described in control...
