Vertical Contracts and Downstream Entry*

We study the implications of different contractual forms in a market with an incumbent upstream monopolist and free downstream entry. We show that traditional conclusions regarding the desirability of linear contracts radically change when entry in the downstream market is endogenous rather than exogenous. By triggering more entry than two-part tariffs, wholesale price contracts can generate higher aggregate output, consumer surplus, and welfare. In light of this, the upstream monopolist may prefer to trade with wholesale price contracts as well as to give up part of its bargaining power when it is high.     

MANAGING FOR RATINGS: REAL EFFECTS OF A CORPORATE RATINGS CRITERIA CHANGE

We exploit a criteria change by Standard & Poor's (S&P) to examine the real effects of a credit ratings change. Using a recalibration by S&P, unrelated to firms’ fundamentals, as a quasi-natural experiment we analyze the impact of a ratings upgrade on the issuance activity, investment, cash holdings, and payout policy of companies. Our findings suggest upgraded firms subsequently issue more debt relative to equity, enjoy lower debt yields, and increase their investment rate and share repurchases. We find limited evidence that upgraded firms decrease their cash holdings. Our results support the view that credit ratings have a real effect on corporations.     

Consumption-investment problem with transaction costs for Lévy-driven price processes

We consider an optimal control problem for a linear stochastic integro-differential equation with conic constraints on the phase variable and with the control of singular–regular type. Our setting includes consumption-investment problems for models of financial markets in the presence of proportional transaction costs, where the prices of the assets are given by a geometric Lévy process, and the investor is allowed to take short positions. We prove that the Bellman function of the problem is a viscosity solution of an HJB equation. A uniqueness theorem for the solution of the latter is established. Special attention is paid to the dynamic programming principle.     

A review of the IFRS adoption literature

This paper reviews the literature on the effects of International Financial Reporting Standards (IFRS) adoption. It aims to provide a cohesive picture of empirical archival literature on how IFRS adoption affects: financial reporting quality, capital markets, corporate decision making, stewardship and governance, debt contracting, and auditing. In addition, we also present discussion of studies that focus on specific attributes of IFRS, and also provide detailed discussion of research design choices and empirical issues researchers face when evaluating IFRS adoption effects. We broadly summarize the development of the IFRS literature as follows: The majority of early studies paint IFRS as bringing significant benefits to adopting firms and countries in terms of (i) improved transparency, (ii) lower costs of capital, (iii) improved cross-country investments, (iv) better comparability of financial reports, and (v) increased following by foreign analysts. However, these documented benefits tended to vary significantly across firms and countries. More recent studies now attribute at least some of the earlier documented benefits to factors other than adoption of new accounting standards per se, such as enforcement changes. Other recent studies examining the effects of IFRS on the inclusion of accounting numbers in formal contracts point out that IFRS has lowered the contractibility of accounting numbers. Finally, we observe substantial variation in empirical designs across papers which makes it difficult to reconcile differences in their conclusions.

Ethical dilemma at work: the viewpoint of bank marketers in Nigeria

The study sought to investigate the major factors that constitute ethical dilemmas for bank marketers in the workplace. The conclusive research design was adopted, and the population of the study consisted of part-time postgraduate students in the faculty of management sciences at the University of Benin who are bank marketers. Research data were analysed using structural equation modelling. Results indicate that sales target and deceptive marketing significantly influence the ethical dilemma faced by bank marketers in Nigeria. The results also showed that respondents’ perception is related to education but not related to sex, marital status and age.

     

Antecedents of brand loyalty in South African retail banking

With new banks entering the South African market and consumers generally not satisfied with their current bank, brand loyalty in the banking sector is receiving greater attention. A gap in the literature exists regarding the issues of bank loyalty and their antecedents in South African retail banking because of the few studies available in the South African context, the new competitive environment in the banking sector, the multi-cultural nature of the market, and the likely switching behaviour by customers. The South African context is a multi-cultural environment and therefore offers a unique background as most previous brand loyalty studies have been in mono-cultural contexts. The purpose of this study was to investigate the antecedents of brand loyalty, including satisfaction, brand relationship quality, customer advocacy, and brand trust in retail banking. We report on a survey of 351 banking customers through SEM using AMOS. While the findings are generally supportive of previous studies, some surprising results are discussed and implications for both theory and practice are highlighted.

     

Bank efficiency in the new European Union member states: Is there convergence?

We employ the stochastic frontier approach and estimate a common frontier in order to examine cost and profit efficiency in the banking systems of the ten new European Union member states over the period 1998-2003. The results indicate a generally low level of cost and an even lower level of profit efficiency, whilst we do not observe marked differences of inefficiency scores across countries. Foreign banks outperform both state-owned and domestic private-owned banks in terms of profit efficiency, though results are less clear in the case of cost efficiency. In addition, β- and σ-convergence criteria indicate some convergence in cost efficiency across the new member states, yet no convergence appears to have been achieved in terms of profit efficiency.
