MARKET INFORMATIONAL EFFICIENCY TESTS AND ITS CRITICS: THE CASE OF EMERGENT CAPITAL MARKETS
2012
Efficient Market Hypothesis (EMH) has attracted a considerable number of studies in empirical finance, particularly in determining the market efficiency of an emerging financial market. Conflicting and inconclusive outcomes have been generated by various existing studies in EMH. In addition, efficiency tests in the emerging financial markets are rarely definitive in reaching a conclusion about the issue. The paper proposes a critical analysis regarding the testing methods of the informational efficiency theory of the capital market and also proposes new perspectives that are meant to relax the strong EMH assumptions in emerging markets.
MODELING OF VOLATILITY IN THE ROMANIAN CAPITAL MARKET
2012
This paper aims to analyze the volatility of capital market in Romania by selecting a portfolio of representative indices (BET BET_FI and RASDAQ_C). In this respect, we want to identify the most appropriate model to estimate volatility by using modern econometric tools and useful GARCH models respectively. The study results highlight that EGARCH(1,1) model has managed to eliminate all traces of statistically significant autocorrelation and ARCH effects from the residuals from daily series, giving an accurate image of the Romanian capital market volatility.
THE LIVING LOGICAL SYSTEM PARADIGM THE ECONOMIC CONCEPT AND THE CONCEPT OF LIVING LOGICAL SYSTEM – NECCESARY AND SUFFICIENT PREDICATES
2012
Through the current research we advocate for the conceptualization of economics and the grouping of the Living Logical System (a concept introduced by prof. Phd. Emil Dinga) on economics, with the purpose of increasing the understanding we have on economic forces. The system which we created, as an extention of the Living Logical System, will be called the Economic Living Logical System. The need for such a research is given by the fact that orthodox economic knowledge is considered a prisoner of the mechanical paradigm.
