Abstract. In recent years more and more complex software packages and more specialized are used to model and to explain economic process. In this paper we present a study on Romanian’s capital market volatility in ARCH and GARCH models using programming environment “R” as new statistical software. We consider the BET and BETC indexes as representative elements of capital market developments. With this study we want to highlight the advantages of using the package “rugarch” that can implement a set of GARCH models and allows the inclusion of external regressors in the variance equation.
