Farmers' perceptions of benefits and factors affecting the adoption of improved dual-purpose cowpea in the dry savannas of Nigeria

This study links participatory research methods, geographic information systems (GIS) techniques, village and household‐level surveys, and a tobit analysis to examine the adoption and impact issues related to a new technology, improved varieties of dual‐purpose cowpea (IDPC), developed by International Institute of Tropical Agriculture (IITA) and International Livestock Research Institute (ILRI) and recently released in Nigeria. The article analyzes factors affecting the adoption and impact of the technology across different socioeconomic domains as defined by degree of market access and population density. The results show multiple benefits from this flexible leguminous crop, many of which relate to the fodder and soil fertility‐enhancing aspects of IDPC rather than higher grain yields per se. The intensity of adoption was affected by different village‐ and household‐level factors in each socioeconomic domain, allowing more sharply defined recommendation domain‐targeting strategies. The multiple research approaches taken also provided useful lessons at different system levels regarding the benefits of, and perceived problems with, this technology for researchers, development practitioners, and policy makers. The collaborative research approaches taken in this study are helping to close the “feedback loop” from farmers back to researchers and others attempting to disseminate the technology, and by doing so, should contribute to faster and more widespread uptake of this technology.     

Post‐formation dynamics in strategic alliances

This paper investigates the occurrence and determinants of post‐formation governance changes in strategic alliances, including alterations in alliances' contracts, boards or oversight committees, and monitoring mechanisms. We examine alliances in the biotechnology industry and find that firms' unique alliance experience trajectories affect the likelihood of such ex post adjustments in these partnerships. Transactional features such as the alliance's scope, its division of labor, and the relevance of the collaboration to the parent firm also bear upon alliances' dynamics. We discuss the implications of these findings and how they complement prior research focusing on alliance design or termination at opposite ends of the alliance life cycle.

Multiparty Competition, Founding Elections and Political Business Cycles in Africa

Political business cycle (PBC) theory and empirics typicallyassume that elections are competitive. Yet, as empirical workon PBCs turns increasingly to developing countries for evidence,this assumption becomes untenable. We propose and test two empiricalhypotheses regarding PBCs: first, we should only see cycleswhen elections involve multiparty competition; secondly, weshould see larger cycles in ‘founding’ elections.Using a new indicator of multiparty competition and macroeconomicdata from Africa, we find strong support for our first hypothesisand moderate support for the second. These findings have implicationsfor democratic transitions and the compatibility of economicand political reform in nascent democracies.     

Takeover Contests with Asymmetric Bidders

Target firms often face bidders that are not equally well informed,which reduces competition, because bidders with less informationfear the winner’s curse more. We analyze how targets shouldbe sold in this situation. We show that a sequential procedurecan extract the highest possible transaction price. The targetfirst offers an exclusive deal to a better-informed bidder,without considering a less well-informed bidder. If rejected,the target offers either an exclusive deal to the less well-informedbidder, or a modified first-price auction. Deal protection devicescan be used to enhance a target’s commitment to the procedure.(JEL G34, K22, D44)     

Deliberate learning in corporate acquisitions: post‐acquisition strategies and integration capability in U.S. bank mergers

This paper introduces a knowledge‐based view of corporate acquisitions and tests the post‐acquisition consequences on performance of integration decisions and capability‐building mechanisms. In our model, the acquiring firm decides both how much to integrate the acquired firm and the extent to which it replaces this firm's top management team. It can also learn to manage the post‐acquisition integration process by tacitly accumulating acquisition experience and explicitly codifying it in manuals, systems, and other acquisition‐specific tools. Using a sample of 228 acquisitions in the U.S. banking industry, we find that knowledge codification strongly and positively influences acquisition performance, while experience accumulation does not. Furthermore, increasing levels of post‐acquisition integration strengthen the positive effect of codification. Finally, the level of integration between the two merged firms significantly enhances performance, while replacing top managers in the acquired firm negatively impacts performance, all else being equal. Implications are drawn for both organizational learning theory and a knowledge‐based approach to corporate strategy research. Copyright © 2004 John Wiley & Sons, Ltd.     

Computer adoption and returns in transition

Across nine transition economies, it is the young, educated, English‐speaking workers with the best access to local telecommunications infrastructures who work with computers. These workers earn about 25 percent more than do workers of comparable observable skills who do not use computers. Controlling for likely simultaneity between computer use at work and labour market earnings makes the apparent returns to computer use disappear. These results are corroborated using Russian longitudinal data on earnings and computer use on the job. High costs of computer use in transition economies suppress wages that firms can pay to their workers who use computers.     

Real assets, financial assets, liquidity and the lemon problem

Return obtained by diversification is based on average quality. Similarly, under asymmetric information, the price at which an asset can be sold reflects the average quality of assets. Therefore, 4under some conditions, sale of an asset under asymmetric information is a useful alternative to diversification. This idea is developed with a model that incorporates a liquidity shock. One key result is that investment in real assets is higher under asymmetric information than under symmetric information. The model can explain why the ratio of real assets to financial assets is higher in emerging economies than in developed countries.     

Buffering and enabling: The impact of interlocking political ties on firm survival and sales growth

Several studies suggest that political ties help firms survive or perform but do not examine the boundary conditions concerning which types of firms and which type of ties help firms. We draw from resource dependence and resource‐based theories to argue that political ties can improve both firm survival (labeled “buffering”) and performance (labeled “enabling”), with weaker firms gaining more from buffering and stronger firms gaining more from enabling. We further examine the relative impact of local and central ties. We test our hypotheses on the television manufacturing industry in China between 1993 and 2003. Results demonstrate the buffering roles of political ties, and under narrower conditions, their enabling roles. Local ties account for these outcomes, while central ties do not provide buffering or enabling benefits. Copyright © 2014 John Wiley & Sons, Ltd.     

Exercise as a Means of Reducing Perceptions of Work‐Family Conflict: A Test of the Roles of Self‐Efficacy and Psychological Strain

Prior research suggests that exercise has positive benefits for individuals and the organizations they work for. Using the literature related to social cognitive theory and exercise, the present study hypothesizes and tests the effects of exercise on two directions of work‐family conflict: work interference with family (WIF) and family interference with work (FIW). Using a sample of 476 working adults, we found that exercise was both positively related to self‐efficacy for managing work‐family conflict and negatively related to reported psychological strain, which in turn were related to reductions in work‐family conflict. Model fit for the data support our contention that exercise indirectly influences work‐family conflict via its direct impact on increased self‐efficacy and reduced psychological strain. © 2014 Wiley Periodicals, Inc.     

Estes' stimulus sampling theory and massed versus spaced advertising schedules

Few studies offer a theoretical explanation of the differential effects of massed and spaced advertising. Consequently, conclusions have been mixed. The authors introduce the stimulus sampling model of spacing effects based on Estes' mathematical learning theory. The model posits that massed repetition generates superior memory at short retention intervals, whereas spaced repetition produces superior memory at longer retention intervals. Data from various studies are analyzed, and implications and potential applications of the model in the advertising context are explored.
