Testing the financial market informational efficiency in emerging states
The Efficient Markets Hypothesis (EMH) has been one of the most influential ideas in the past years and highlights that assets prices incorporate all information rationally and instantaneously. The last financial crisis has led to criticism of this hypothesis. Many practical observations concerning the reaction of investors, but also the mechanisms for the information encompassing in the price of stocks, come to highlight the aspects of 'market inefficiency'. Despite its simplicity, the EMH is surprisingly difficult to test and considerable care has to be exercised in empirical tests. It has attracted a considerable number of studies in empirical finance, particularly in determining the mar…
The Speed of Incorporating Information into Prices
Abstract To determine the speed of adjusting asset prices to the latest market information, investors usually resort to semi-strong form efficiency tests. Semi-strong form efficiency is based on the assumption that stock prices adjust rapidly as a result of new public information. The objective of the event study conducted in this paper was to examine whether new information is incorporated into the share price in a single price change after its public distribution. We analyzed the price behaviour of companies listed under Category I of the Bucharest Stock Exchange around events such interim result announcements between June and November 2012.
Discretionary vs nondiscretionary in fiscal mechanism – non-automatic fiscal stabilisers vs automatic fiscal stabilisers
The goal of the present study is to increase the intelligibility of macroeconomic phenomena triggered by governmental intervention in economy by means of fiscal policies. During cyclical movements, fiscal policy can play an important role in order to help stabilise the economy. But discretionary policy usually implies implementation lags and is not automatically reversed when economic conditions change. In contrast, automatic fiscal stabilisers (SFA) ensure a prompter, and self-correcting fiscal response. The present study aims to tackle the topic of discretionary vs nondiscretionary characteristic of fiscal stabilisers (SF). In this context, the scope of the research undertaking is to laun…
The Capital’s Election Criteria Used in the Financial Management of a Company’s Financing Decision
The optimization of the capital structures of a company after the cost criteria represents a profitable activity, provided that it is well conceived, organized and carried out. For this consideration, the capital’s structure and their medium cost is an important profit source for the company, so the profit comes from this source, and not from the exploitation activity or other financial sources or traditional exceptive. In conclusion, the cost of the capital has to be previewed; the company has to build an adequate strategy and tactical procedures to accomplish this challenge. Besides the capital’s cost, in this paper we present some other criteria that can interfere in the choice of the fi…
Effects of Behavioural Finance on Emerging Capital Markets
Abstract A recent common view of finance experts is that it is becoming increasingly difficult to understand how the economy as a whole works. Although the efficient market theory might be considered an ideal model enabling the interpretation of market behavior, it has begun to lose ground, and the rationality hypothesis failed to explain the excessive volatility of the returns and trading volume recorded on both developed capital markets and emerging ones. Adding the behavioral finance perspective to the equation can help us to understand better how market agents will react. In this article, we investigate the factors that may explain the trading volume evolution on two emerging capital ma…
Effects of Behavioural Factors on Human Financial Decisions
Abstract In this article, we investigate the factors that may explain the trading volume evolution on two emerging capital markets, Romania and Brazil. We analyze the impact of both investors who ground their trading behaviour on rational expectations and investors who show psychological and emotional facets of the human decision, which we call behavioural errors, as independent variables on the trading volume as dependent variable. The results indicate that trading is influenced by the investors’ irrational behaviour. Thus, the rationality hypothesis can be rejected for both capital markets.
FRACTALITY EVIDENCE AND LONG-RANGE DEPENDENCE ON CAPITAL MARKETS: A HURST EXPONENT EVALUATION
Since the existence of market memory could implicate the rejection of the efficient market hypothesis, the aim of this paper is to find any evidence that selected emergent capital markets (eight European and BRIC markets, namely Hungary, Romania, Estonia, Czech Republic, Brazil, Russia, India and China) evince long-range dependence or the random walk hypothesis. In this paper, the Hurst exponent as calculated by R/S fractal analysis and Detrended Fluctuation Analysis is our measure of long-range dependence in the series. The results reinforce our previous findings and suggest that if stock returns present long-range dependence, the random walk hypothesis is not valid anymore and neither is…
Managing Academic Internationalization: A Culture-Based Approach
Abstract The goal of the present paper is apply the blue-ocean strategy to the current status of the higher education system, with a major focus on managing cultural diversity in a global world. Universities nowadays represent poles of excellence in terms of cultural innovation, knowledge creation and transfer to the industry, an interface between home and host country as regards academic mobility (teaching and research mobility); they have a significant role in promoting cultural values and informed intercultural communication, creating academic consortia as well as interacting with the local and business communities. The paper shall also redefine: the role of university managers in the co…
Towards a sustainable well-being
Given the need of a new economic paradigm for the achievement of a world of sustainable wellbeing, this paper presents the main findings from the literature on sustainable well-being. We try to identify a few approaches of measurement, highlighting strengths and weaknesses. We analyzed Romania's position in the global context in terms of happiness index. Are sustainable well-being indicators a good guide for policy-making? Also, the paper discusses the role of education in ensuring the sustainable well-being.
