We investigate the properties of the returns of the main emerging stock markets from Europe by means of complex networks. We transform the series of daily returns into complex networks, and analyze the local properties of these networks with respect to degree distributions, clustering, or...

We reassess the relationship between money and output using quarterly data from the US economy. We use several tools based on wavelets, the wavelet power transform and the wavelet coherence with which we analyze this relationship in both time and frequency. We find evidence of a weaker...

One of the controversial issues in macroeconomics consists in whether the macroeconomic time series are better characterized as being driven by permanent shocks or by temporary shocks. We provide here new evidence using a recent unit-root test based on the wavelets methodology.

We investigate the existence of nonlinearities in the dynamics of the returns of stock markets indices from CEE economies. We use several types of nonlinear tests. We discuss the implications of the results with respect to the efficient market hypothesis.

In this paper I compare the calibration technique with the Bayesian approach in the context of econometric methods of estimating structural models. I use the real business cycles model to apply both techniques. The model is calibrated and estimated for Romanian economy using quarterly data. I...

In this study I use the Bayesian VAR framework to forecast the dynamics of output for the Romanian economy. I estimate several versions of Bayesian VARs and compare them in terms of forecasting statistics with two standard models, the OLS and the unrestricted VAR, as well as with a naïve...

This article shows that the possibility for our country to reduce the unemployment by using the means of traditional macroeconomic policies are limited due to the contraints imposed by the inflation targeting regime and due to the restrictions in governement expenditures. The most realistic ways...

We investigate the existence of nonlinear patterns in the dynamics of the main stock index returns in Romania. We use daily closing data of the BET stock index series from 2004 to early 2010. Based on several tests for nonlinearity we reject the null hypothesis of linearity. We use several types...

Recently, a new test for nonlinearity and chaos was proposed, the noise titration technique. I discuss in this paper its relevance for the case of economic time series. I apply the test on two relevant datasets for which previous assessments exist, both simulated and real data. Compared to other...

Using the Bayesian approach, a small open economy DSGE model was estimated using a sample of quarterly data for three Central and Eastern Europe economies, Czech Republic, Hungary and Poland. The hypothesis that central banks react to exchange rate movements was tested using posterior odds...
