Estimates of the macroeconomic indicators are carried out with an econometric model which tries to estimate the medium-term evolution of the Moldovan economy. The forecast takes into account the economic influence of the main economic partners of the Republic of Moldova and the internal...

Based on the 2012 Version of the Romanian Macromodel, the first section of this paper discusses the evolution of the Romanian economy in 2014. The previous simulations were revised taking into account the changes in the internal and external socio-economic conjuncture or in the available...

The paper describes the version (2012) of the Romanian economic macromodel2. The model has been constructed taking into account the important consequences induced by the integration of the country into the European Union and by the world crisis. Some supplementary requests of the government...

Economic time series are, in their vast majority, integrated series so, their modelling procedure stumbles upon the problem of spurious regression. When existent, cointegration is the simplest way of eliminating the illogical correlation established between time series due to the presence of...

The paper analyzes the circumstances in which the combination of forecasts yields better results than the use of the forecasts separately. We propose a method of combining forecasts based on their efficiency on long and medium-term using as benchmarks the combination of forecasts based on...

Inference about predictive ability is usually carried-out in the form of pairwise comparisons between two forecasting methods. Nevertheless, some interesting questions are concerned with families of models and not just with a couple of forecasting strategies. For instance: Are time-series models...

The study aims to extend the GARCH type volatility models to their nonlinear TAR (Tong, 1990) and STAR-based (Terasvirta, 1994) counter parts where both the conditional mean and the conditional variance processes follow TAR and STAR nonlinearity. The paper further investigates the models under...

The paper provides a critical assessment of the main forecasting techniques and an evaluation of the superiority of the more advanced and complex models. Ultimately, its scope is to offer support for the rationale behind of an idea: GARCH is the most appropriate model to use when one has to...

The problem of forecasting the economic systems' activity over a large time horizon is the main concern of both the researchers in the economic field and the system managers. In most cases, its solving is reduced to simulating the structure of the economic indicators which render the system...

This paper tests the relationship between above market returns and beta, size, leverage, book-to-market equity and earning-price ratios for the Bucharest Stock Exchange common stocks. Results from cross-sectional regressions document that both book-to-market equity and earning-price ratios are...
