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 Barometer of the Romanian Economy" intends to be a mirror of the evolution of the Romanian economy and, at the same time, to be its global indicator of the state and trend. "The Barometer of the Romanian Economy" was first published some years ago in Microeconomia aplicata, on the...

The purpose of this paper is to study and quantify the impact of the human capital in the process of economic growth in Romania over the 1990-2002 period. We will consider an augmented Cobb-Douglas production function to include the human capital, approximated by the number of schooling years...

In this paper I estimate a New Keynesian Model with sticky prices for the Romanian economy for the period 1991-2002, using quarterly data. The estimation was made in Dynare using the Bayesian approach. The degree of the price stickiness is moderate. The model makes good predictions in terms of...

This paper analyses the dynamics of the Romanian economy in the 1990-2002 period, both on aggregate terms and using a sectoral decomposition. We worked in a neoclassical framework using a standard Cobb Douglas function with a Hicks neutral technology. We decomposed the economy into four sectors...
