Stock Markets, Banks, and Economic Growth: Empirical Evidence from the MENA Region

Abstract: Since few decades, a wide theoretical debate is concerned with the fundamental relationship between financial development and economic growth as well as the separate impact of banks on growth and financial markets on growth. Recent studies shed some light on the simultaneous effect of banks and financial development on growth. The empirical study is conducted using an unbalanced panel data from ten MENA region countries. Econometric issues will be based on estimation of a dynamic panel model with GMM estimators. Thus, peculiarities of MENA region countries will be detected. The empirical results reinforce the idea of no significant relationship between banking and stock market development, and growth. The association between stock markets and growth is even negative after controlling for bank development. This lack of relationship must be linked either to underdeveloped financial systems in the MENA region that hamper economic growth or to unstable growth rates in the region that affect the quality of the association between finance and growth. Moreover, in most transition economies the stock markets are very thin. This may lead to excessively volatile share prices. According to Singh (1997), stock price volatility may seriously hamper economic development.

Asymmetries in Stock Returns: Statistical Tests and Economic Evaluation

Abstract: We provide a model-free test for asymmetric correlations in which stocks move more often with the market when the market goes down than when it goes up, and also provide such tests for asymmetric betas and covariances. When stocks are sorted by size, book-to-market, and momentum, we find strong evidence of asymmetries for both size and momentum portfolios, but no evidence for book-to-market portfolios. Moreover, we evaluate the economic significance of incorporating asymmetries into investment decisions, and find that they can be of substantial economic importance for an investor with a disappointment aversion (DA) preference as described by Ang, Bekaert, and Liu (2005). , Oxford University Press.

The building stock as a research object

Abstract: Activities related to refurbishment of the building stock as a percentage of all building work have been constantly growing in most central European countries over the last 20 years. The main argument in this paper is the need to improve knowledge about composition of the existing building stock, the dynamics of its transformation and to relate this to the different actors in property professions. A review is presented of traditional and new sectoral research approaches to partial or national building stocks to provide a context for assessing an integrated approach to the German building stock with methodological propositions for improving the synergy between different sectoral approaches. Detailed consideration is given to life cycle analysis, building product modelling, historical building research and new simulation techniques. Sustainability indicators and the integration of building stock, infrastructure and land use are discussed. Depuis une vingtaine d'annees, les activites liees a la rehabilitatio...
