Developments of analytical solutions to nonlinear equations provide very good physical insights into the nonlinear phenomena. The nonlinear transient thermal responses of extended surfaces have been widely studied analytically with the aid of different methods based on power series solutions....

With fiscal adjustment proceeding quickly in Bulgaria and given the weak economic growth environment, there is keen interest in making the budget composition more growth friendly. This paper quantifies the short-term impact of fiscal policy on economic activity in Bulgaria using econometric and...

В статье рассматривается проблема мониторинга валютного рынка. Для исследования состояния рынка в режиме реального времени предложено использовать...

Only a few empirical studies have analyzed the relationship between fiscal multipliers and the underlying state of the economy. This paper investigates this link on a country-by-country basis for the G7 economies (excluding Italy). Our results show that fiscal multipliers differ across...

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...

Does the state of the business cycle matter for the effects of fiscal policy shocks on GDP? This study analyses quarterly German data from 1976 to 2009 in a threshold SVAR, expanding the SVAR approach by Blanchard and Perotti (2002). In a linear benchmark SVAR, the analysis finds that hiking...

In this paper we assess the short-term forecasting power of different time series models in the electricity spot market. In particular we calibrate AR/ARX ("X" stands for exogenous/fundamental variable—system load in our study), AR/ARX-GARCH, TAR/TARX and Markov regime-switching models to...
