The determinants of commercial banking profitability in low-, middle-, and high-income countries

Using a broad bank-level dataset and the GMM estimator technique described by Arellano and Bover (1995), this paper analyses how bank-specific characteristics, macroeconomic variables, and industry-specific factors affect the profitability of 10,165 commercial banks across 118 countries over the period from 1998 to 2012. Grouping the countries according to three income levels, we show that the determinants of bank profitability included in our model can explain existing profitability differences among commercial banks in low-, middle-, and high-income countries. The profitability determinants vary quite widely across the different levels of income in terms of significance, sign and size of the effect. The level of income has thus an important impact on the determinants of bank profitability.     

Product Market Competition,Managerial Incentives and Firm Valuation

This paper contributes to the very small empirical literature on the effects of competition on managerial incentive schemes. Based on a theoretical model that incorporates both strategic interaction between firms and a principal agent relationship, we analyse the relationship between product market competition, incentive schemes and firm valuation. The model predicts a nonlinear relationship between the intensity of product market competition and the strength of managerial incentives. We test the implications of our model empirically based on a unique and hand‐collected dataset comprising over 600 observations on 200 Swiss firms over the 2002–2005 period. Our results suggest that, consistent with the implications of our model, the relation between product market competition and managerial intensive schemes is convex indicating that above a certain level of intensity in product market competition, the marginal effect of competition on the strength of the incentive schemes increases in the level of competition. Moreover, competition is associated with lower firm values. These results are robust to accounting for a potential endogeneity of managerial incentives and firm value in a simultaneous equations framework.     

Fares and Free Riders on the Information Highway

Public policy issues around access to networked information are explored and examined. Long viewed as the quintessential public good, information has evolved into a critically important market commodity in little more than a generation. New technologies and a political climate in which the meaning of universal access to information is no longer commonly understood and in which its importance is no longer taken for granted pose significant challenges for American society. Libraries, as information commons, offer the means of meeting those challenges. Historical, economical, and professional factors that shape the conflict are described and discussed.     

Antecedents of emotional attachment of social media users

Emotional attachment has been documented to be an effective basis for consumer loyalty behaviors in many contexts; however, not much has been offered for new service formats enabled by information technology. This study explores the emotional attachment of social media users in terms of personality traits of users and websites. Drawing on literature on brand personality and brand–self congruence, this research proposes that a match between user’s individual personality and the personality traits of the digital artifacts promotes affective connection to social media websites. The social media, to which the user becomes emotionally attached, therefore becomes part of one’s self-definition and representation in the digital world. Self-expressiveness is also investigated as a motivational driver that helps users form such an emotional bond. Individuals with higher motivation to express themselves are more likely to develop an emotional attachment to social networking sites, exhibit loyal behavior, and experience a stronger effect than self-website congruence on emotional attachment. Results of this research provide support to the proposed relationships. Theoretical and managerial implications are elaborated in the discussion.     

Free entry and stability in a cournot model

In a Cournot model for a single homogeneous good, we study simultaneously two stability properties of a Cournot equilibrium: the stability of a continuous quantity adjustment process with a fixed number of firms and the stability relative to entry. Under usual assumptions, we show that these two properties are consistent—i.e., there exists an equilibrium that is stable in both senses—and determine quite sharply the number of active firms.     

Social Security, Optimality, and Equilibria in a Stochastic Overlapping Generations Economy

Social security institutions implement intergenerational transfers and distribute risks over time. To compare various social security designs, we study an overlapping generations model with demographic shocks. Production takes place through a neoclassical production function subject to productivity shocks. We give a near characterization of optimal allocations. We study rational expectations equilibria when contributions are mandatory, based on labor and capital income. We also describe the equilibria of an economy with a voluntary pay-as-you-go social security fund, and show that they have a long-run optimality property. An example with Cobb–Douglas production and utility functions illustrates the results.     

On optimality in intergenerational risk sharing

Summary. This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts are considered, including interim and ex ante optimality. We show that, at an equilibrium with a productive asset (land) and sequentially complete markets, the intervention of a government may be justified, but only to improve risk sharing between generations. If markets are incomplete, constrained interim optimality is investigated in two-period lived OLG economies. We extend the optimality properties of an equilibrium with land and give conditions under which introducing a pay-as-you-go system at an equilibrium would not lead to any Pareto improvement.

Social Security with Heterogeneous Populations Subject to Demographic Shocks

In a previous paper, we showed how a pay-as-you-go social security scheme, based on voluntary contributions, can be an appropriate institution to reach an optimal sharing of risks among generations in the presence of demographic uncertainties. We study here the functioning of such schemes when there are different population strata, with different demographic shocks and wages. We show that while a collective voluntary pay-as-you-go scheme can provide efficient intergenerational risk sharing, it is likely to be destabilized by pensions funds specialized by agents' types. This is true both when there is a complete set of contingent markets, where the risk pooling capabilities of a collective fund are potentially of less interest, and when markets are incomplete. In this last circumstance, a collective fund may help the living agents to share their intragenerational risks. However, we show that the resulting allocation does not Pareto dominate the outcome of individual funds by agent types, and that there are incentives for agents to separate from any collective organization.     

The Tourism Market's Response to the 2009 Black Saturday Bushfires: The Case of Gippsland

One of the key roles of a destination marketing organization (DMO) is to portray their destination in such a way that it is both appealing and inviting to their existing and potential tourism market. A challenge faced by a DMO in the regional Victorian destination of Gippsland in Australia, is the fact that they also have to manage unanticipated sudden changes in market perceptions that may occur in response to a disastrous event. The reoccurring natural disasters of this region (fires, floods and drought)—the most recent being the 2009 Black Saturday bushfires, deemed Australia's worst natural disaster in history—make it imperative that DMOs can respond effectively. This article presents the findings of an exploratory research project designed to investigate the tourism market's response to this particular disastrous event. The primary aim of the research was to better understand how a large-scale disaster impacts upon the tourist's destination image and visitation intentions, and the role of the media in these deliberations. Focus group research reveals the post-disaster media interpretations, images, and visitation intentions of intrastate and interstate, regional and metropolitan tourists. Differences are observed in relation to the participants' geographic location and distance from the fires and their understandings of the event, including their reflections on media coverage. Varying perceptions among the participants of the impact of the fires, the travel risk, and subsequent travel intentions are discussed. Managerial implications relating to media management and the refinement of future disaster management strategies are also presented.     

RUMORS AND SOCIAL NETWORKS

This article studies the transmission of rumors in social networks. We consider a model with biased and unbiased agents. Biased agents want to enforce a specific decision and unbiased agents to match the true state. One agent learns the true state and sends a message to her neighbors, who decide whether or not to transmit it further. We characterize the perfect Bayesian equilibria of the game, show that the social network can act as a filter, and that biased agents may have an incentive to limit their number.
