The performance of newly privatized firms in selected MENA countries: The role of ownership structure, governance and liberalization policies

The paper analyzes 95 newly privatized firms (NPFs) in four Middle Eastern and North African countries (Egypt, Morocco, Tunisia, and Turkey). We find that these firms experienced significant increases in profitability and operating efficiency, and significant declines in employment and leverage. We also document strong performance improvements for firms that did remain state-owned, that were not sold to foreigners, and that came from Egypt. Job losses are higher in Egypt and in firms where the state is no longer in control. Also, the results indicate that revenue firms and NPFs in Morocco display significantly less leverage than control firms and those from other countries. We find that profitability changes are negatively related to state control and positively related to foreign ownership. Trade openness, change in real GDP over the privatization window, index of investor protection, and foreign ownership are important determinants of the changes in sales efficiency and output. These findings suggest that NPFs become more productive in environments where property rights are better protected and enforced and that foreign investors influence firms' productivity through their monitoring role.     

Stock markets, banks, and economic growth: Empirical evidence from the MENA region

Over the last four decades, a wide theoretical debate is concerned with the fundamental relationship between financial development and economic growth. Recent studies shed some light on the simultaneous effect of banks and financial system development on growth rather than a separate impact. The empirical study is conducted using an unbalanced panel data from 11 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 bank development and economic growth is even negative after controlling for stock market development. This lack of relationship must be linked to underdeveloped financial systems in the MENA region that hamper economic growth. Then, more needs to be done to reinforce the institutional environment and improve the functioning of the banking sector in the MENA region. Based on these results, other regions at the same stage of financial development such as Africa, Eastern Europe or Latin America should improve the functioning of their financial system in order to prevent their economies from the negative impact of a shaky financial market.     

Convergence and performance of the peeling wavelet denoising algorithm

This note is devoted to an analysis of the so-called peeling algorithm in wavelet denoising. Assuming that the wavelet coefficients of the useful signal are modeled by generalized Gaussian random variables and its noisy part by independent Gaussian variables, we compute a critical thresholding constant for the algorithm, which depends on the shape parameter of the generalized Gaussian distribution. We also quantify the optimal number of steps which have to be performed, and analyze the convergence of the algorithm. Several implementations are tested against classical wavelet denoising procedures on benchmark and simulated biological signals.     

The impact of capital requirements on banks’ cost of intermediation and performance: The case of Egypt

In 1991, the Central Bank of Egypt increased the minimum capital requirements for the banking industry vis-à-vis risk-weighted assets to 8%, along the lines proposed by the Basel Committee on Banking Supervision. In this paper, we investigate the effects of capital regulations on cost of intermediation and profitability. Higher capital adequacy increases the interest of shareholders in managing banks’ portfolios. The result is a higher cost of intermediation and profitability. A number of factors have increased the cost of intermediation in the post-capital regulation period: higher capital-to-assets ratios, an increase in management efficiency, an improvement of liquidity and a reduction in inflation. The reduction in output growth countered these effects. A number of factors contributed positively to banks’ profitability in the post-regulation period: higher capital requirements, the reduction in implicit cost, and the increase in management efficiency. The reduction in economic activity had opposite effects on banks’ profitability. Overall, the results support the Central Bank's efforts to enforce capital regulations to improve the performance of the banking sector in Egypt.     

Asset Pricing and Cost of Equity in the Tunisian Banking Sector: Panel Data Evidence

In spite of popularity and theoretical simplicity of the one-factor Capital Asset Pricing Model (CAPM) used in the valuation of financial assets, researchers are more concerned with the important extension proposed by Fama and French (1993) , that is, the Three-Factor Pricing Model (TFPM). Alongside beta, average stock returns could be explained by some size and book-to-market supplementary effects. With these two complementary models, estimation of the cost of equity is carried out for the Tunisian banking sector. In order to account for inter-individual heterogeneity, estimation of parameters is conducted according to random coefficient specifications within the context of panel data analysis.     

Trialogue on Facebook pages of grocery stores: Customer engagement or customer enragement?

Abstract

The pervasiveness of social media is compelling businesses to review their way of managing customer experiences. Businesses use social media to interact and engage with customers. Several studies have studied why businesses have adopted social media. However, there is a dearth of research as to why customers interact with businesses on social media in the grocery sector. This paper aims to explore how and why customers react to corporate messages on Facebook pages of Tesco and Walmart. Netnography approach was adopted to gain an insight into the various ways customers engage with the grocery stores on its Facebook pages. This study reveals that social media empower customers, influence the relationships customers have with grocery stores and generate customer engagement. Findings also show that the social customer is both a curse and a blessing to Tesco and Walmart when they create or destroy value for the business. This paper contributes to knowledge by (1) uncovering how customers react to corporate and customer posts on corporate Facebook pages; (2) showing how value can be created and destroyed; and (3) proposing a model illustrating how the main constructs of the study are interconnected: social media, relationship marketing, customer empowerment and customer engagement.     

The Short– and Long–run Performance of New Listings in Tunisia

This study examines abnormal stock market returns of new listings on the Tunisian Stock Exchange. Substantial positive abnormal returns are found on the first listing day and this finding is similar to that obtained in other countries. Subsequent performance is poor and investors who bought shares at the close of trading on the first day would have lost about 22% against the Tunis Stock Exchange index over a three–year period. The possible causes of this are investigated. Among the factors found in the literature that possibly affect the level of long–term performance, only the state of the IPO market, the initial return, the delay in reaching the ‘first market price’ and the size of the firms have significant coefficients. This result is supportive of the traditional fad’s interpretation of long–term underperformance.     

Trade and labour standards: theory and new empirical evidence

Recent trade negotiations, both at the regional and multilateral level, have seen a resurgence of the issue of trade and labour standards. Labour interests in high-standards countries argue that low labour standards are an unfair source of comparative advantage, and that increasing imports from low-standards countries will have an adverse impact on wages and working conditions in high-standards countries, thus leading to a race to the bottom of standards. For low-standards countries, there is the fear that this is just a form of disguised protectionism and that the imposition of high labour standards upon them is equally unfair since it will erode their competitiveness, the latter being largely based on labour costs. Our objective in the present paper is to cast some light on the above debate from both a theoretical and empirical perspective. In particular, we first discuss some possible theoretical links between labour standards and comparative advantage through their effects on the terms of trade. We then investigate empirically the relationship between labour standards, comparative advantage and export performance. Overall, our empirical results suggest that caution should be exercised before drawing broad conclusions on the magnitude and direction of these effects.     

The bonding effects of relationship value and switching costs in industrial buyer–seller relationships: An investigation into role differences

Despite the established importance of buyer–seller relationships in B-to-B markets, research to determine the differential effects that keep suppliers and customers in a relationship has been scarce. Referring to transaction cost analysis, this study investigates how switching costs and relationship value as perceived by each side unfold their bonding forces in such a relationship. Based on a large scale survey administered in Germany, Korea, New Zealand, and Argentina among marketing/sales and purchasing managers the study shows that relationship value has a stronger impact on intentions for relationship enhancement, search for alternatives and switch intention than switching costs for both buyers and sellers. Only with regard to relational tolerance and only for buyers do switching costs play a greater role than relationship value. Furthermore, buyers base their future relationship intentions more on the current state of the relationship than suppliers. Our results suggest that role differences must be taken into account when studying institutional arrangements in B-to-B markets.
