Moral hazard and Marshallian inefficiency: Evidence from Tunisia

We formalize the link between optimal cost-sharing contracts and the production technology in the presence of moral hazard by appealing to several well-known results from duality theory. Building on intuitions from the interlinkage literature, we show that optimal contractual structure is determined by the (i) substitution possibilities that exist between different observable factor inputs, as well as (ii) between these inputs and unobservable effort. We endogenize contractual choice using landlord characteristics as instruments, exploiting the fact that, in our dataset, landlords interact with several tenants and vice versa. The approach is applied to an unbalanced plot-level panel of cost-sharing contracts in a Tunisian village, using a translog representation of the restricted profit function. Contractual terms are found to be a significant determinant of input use and therefore lead to Marshallian inefficiency, while the optimality of the underlying contractual structure is rejected.     

Does ethnic diversity decrease economic interactions? Evidence from exchange networks in rural Gambia

Using a unique dataset collected in 59 rural Gambian villages, we study how ethnic heterogeneity is related to the structure of four economic exchange networks: land, labour, inputs and credit. We find that different measures of village‐level ethnic fragmentation are mostly uncorrelated with network structure. At a more disaggregated level, household heads belonging to ethnic minorities are not less central than those from the predominant ethnicity in any of the networks and, at the dyadic level, the fact that two households share ethnicity is not an economically significant predictor of link formation. Our results indicate that, in the particular setting of our study, the structure of the exchange networks is better defined by other variables than ethnicity and that ethnic heterogeneity is unlikely to be a driver for sub‐optimal economic exchanges.     

Fritz Redlich, 1892-1978: The Man and the Scholar

A bstract . Fritz Redlich (1892-1978) played a leading role in the development of the analytic approach in history and in establishing the new institutional history that combines entrepreneurial and business history and sociology. A member, in economics , of the German historical school , he spent 16 years in the chemical industry before the triumph of Nazism forced him to emigrate from Germany in 1936. After teaching at various colleges until 1942, he spent the rest of his life doing research in the libraries of Harvard University , producing several notable works in economic history , including a classical study of American banking , and pioneering in entrepreneurial history.     

Accounting students’ choice of blended learning format and its impact on performance and satisfaction

Using online platforms to deliver educational content, some institutions have developed blended courses that combine the advantages of online instruction with traditional face-to-face (F2F) teaching. This study compares accounting student performance and satisfaction in two blended formats with similar content and design, i.e. F2F+ vs. Online+ courses. It also assesses the characteristics of students who choose the latter option over F2F+ courses. Students in four advanced accounting subjects were surveyed and their course performance was obtained. Results indicate that the main determinants of students’ decision to register for an Online+ course are retaking the course, increased weekly work hours, and belief that this type of blended course facilitates learning. Results show that students in advanced accounting courses with equivalent content and design perform similarly and have the same level of course satisfaction across course delivery formats, as hypothesized under equivalency theory.     

Systèmes De Gestion Des Ressources Humaines Et Performance Organisationnelle

Résumé ** :  La gestion des ressources humaines et son effet sur la performance de la firme représentent encore de nos jours une zone d'indétermination. Plusieurs théories tentent d'ailleurs d'expliquer cette importante relation. C'est l'approche configurationnelle des ressources humaines qui servira de filtre théorique à cette recherche. Validant cette approche auprès de 46 entreprises financières canadiennes, nous avons démontré, en partie du moins, la robustesse de cette approche stratégique de gestion des ressources humaines. Il ne fait aucun doute qu'une telle approche représente une alternative stratégique intéressante, capable d'accroître l'efficacité de nos firmes dans ce monde économique impitoyable et mondialisé.     

Human resources professionals and the cost/benefit argument: rational persuasion in action in municipal organizations

Abstract

This study examines the use of the cost/benefit argument by human resources professionals in municipal sector organizations. The analysis compares their approach to the social influence exercised by line managers. Drawing from critical incidents generated from in-depth interviews, the results suggest that human resources professionals and line managers use the cost/benefit argument in much the same way with greater use of the weak form. Both groups exert influence through rational persuasion in the form of ‘light’ financial arguments. A second wave of data collection was initiated to add the perspective of city managers relative to the use of this form of rational persuasion by human resources professionals and public works managers. Content analysis of the interviews conducted with city managers was revealing of different views of the public works and human resources departments, suggesting that the use of the stronger form of the cost/benefit argument by human resources professionals may actually be associated with lower influence capability.     

Transformation of the Information Technology Function in Organizations: A Case Study in the Manufacturing Sector

The main goal of this study is to better understand the nature of transformations of the Information Technology (IT) function in organizations. A conceptual framework combining a typology of the IT function and key elements of the theory of punctuated equilibrium was developed and applied in a case study of a manufacturing company. Our results suggest that IT functions are transformed in response to various pressures that push it toward change. However, these pressures need to be channelled through a catalyst consisting of three independent elements: (a) the vision of the enterprise concerning the potential value of IT tools, (b) the degree of Chief Information Officer's participation in strategic decision making, and (c) the level of IT knowledge among members of the executive team. Finally, our results challenge the notion that all IT functions tend towards the same optimal profile over time. Copyright © 2011 ASAC. Published by John Wiley & Sons, Ltd.     

Understanding Attitude and Behavior of Canadian Consumers Toward Organic Wine

The main objective of this study is to identify the determinants of organic wine purchase and understand their effect in order to illustrate what influences whether Canadian consumers are willing to buy this special type of wine. The data for this study were collected across Canada by means of an online self-administered consumer questionnaire survey. Our major findings indicate that the attitude toward organic wine is defined mainly by consumers’ health consciousness and is negatively influenced by the wine involvement pleasure experienced with regular wine. Interestingly, Canadians are not forming positive attitudes toward organic wine based on their knowledge of organic production and its offering. The main predictors of organic wine purchase are attitude toward organic wine and wine involvement interest. Unexpectedly, price consciousness was not found to be a good predictor of organic wine purchase.
