Technological opportunism effects on IT adoption,intra-firm diffusion and performance: Evidence from the U.S. and Spain

The paper pursues a joint analysis of the direct influence of the level of a firm's technology opportunism capability on performance and on the adoption and intra-firm diffusion of Internet-based technologies. The study here examines the mediating effect that intra-firm diffusion exerts on the relationship between capabilities and performance. This study uses the results from a survey of 100 Spanish and 109 American franchise firms. Results indicate that the firm's level technological opportunism influences the adoption and intra-firm diffusion of technology and also has a positive impact on performance. While intra-firm diffusion is a driver of performance, adoption has no influence. Finally the indirect impact of technological opportunism on performance differs across countries. While for American firms, the integration of technologies into activities that related to communication with partners has a positive impact on performance; Spanish managers should focus on the integration of these technologies into back-end functionalities.     

An Economic Analysis of Targeting Soil Conservation Measures with Respect to Off-site Water Quality

This paper analyses the advantages and disadvantages of targeting soil conservation measures on the basis of off-site water quality goals. The Stratford Avon watershed in Perth County and the Big Creek watershed in Middlesex County, both located in southwestern Ontario, are used as case studies. Targeting criteria, used as proxies for measuring the contribution to off-farm damage from particular parcels of crop land, are based on the physical characteristics of the parcels. Alternative conservation tillage practices include fall chisel ploughing, ridge planting, no tillage and buffer strips. At each level of the targeting criteria, the reduction in off-farm damage is estimated using the Guelph Model for Evaluating the Effects of Agricultural Management Systems on Erosion and Sedimentation (GAMES). Economic targeting criteria are based on the value of improved water quality under a conservation practice minus the on-farm costs of adoption of that practice. Targeting conservation policies on the basis of reduction of off-farm damages can result in greater efficiency in public policy. The authors conclude that further efforts in targeting conservation policies have the potential to improve the cost effectiveness of soil conservation programs if technical and administrative problems can be overcome. L'article analyse le pour et le contre du ciblage des mesures de conservation des sols sous l'angle de la qualité de l'eau à l'aval. Le bassin versant Stratford Avon dans le comité de Perth et celui de Big Creek dans le comté de Middlesex, tous deux situés dans le sud-ouest de l'Ontario, sont utilisés comme études de cas. Les critères de ciblage utilisés comme valeurs d'approximation dans la détermination de la part des dégâts causés à l'aval qui est attribuable à des parcelles agricoles données, sont basés sur les caractères physiques des parcelles. Les diverses pratiques de travail de conservation comparées sont la labour au chisel, la culture sur billons, la culture sans labour et l'établissement de bandes riveraines. A chaque niveau des critères de ciblage, la réduction des dégâts infligés à l'aval des exploitations est estimée selon le Modèle d'évaluation des effets des systèmes d'exploitation agricole sur l'érosion et la sédimentation de l'Université de Guelph (GAMES). Les critères de ciblage économiques reposent sur la valeur attribuée à l'amélioration de la qualité de l'eau par une pratique de conservation donnée, moins les coûts réels d'adoption de l'exploitant à cette pratique. Le ciblage des politiques de conservation en fonction de la réduction des dégâts causés à l'aval de l'exploitation peut rendre plus efficientes les politiques du secteur public. Il ressort de ces études que les politiques de ciblage des mesures de conservation offrent la possibilité d'améliorer la rentabilité des programmes de conservation du sol, pour autant parvienne à surmonter les problèmes techniques et administratifs.     

Presidential Address: Mathematics in economics and econometrics

Abstract The paper discusses the choices of mathematical approaches in economics and econometrics, in particular, approaches that either (a) aim for a sharp result or (b) use the least restrictive assumptions. It is argued that, while the choice (a) often necessitates strong mathematical assumptions, choice (b) may lead to only partial identification and may require using less familiar mathematical techniques. This is discussed in the context of the problem of defining a probability density: existence may fail in function spaces; even after imposing assumptions that ensure existence, the problem is not well posed. A density function may not exist for economic variables as a consequence of institutional rigidity such as an income supplement. The apparatus of generalized functions provides the general solution to identification and well‐posedness of density, but at the cost of less sharp results and greater mathematical complexity.

The Increasing Selectivity of Foreign Aid, 1984–2003

The Monterrey Consensus includes the idea that foreign aid is more effective when targeted to countries with sound institutions. We examine the extent to which foreign aid, bilateral and multilateral, is “selective” in terms of democracy and property rights/rule of law. We find that multilateral assistance is more selective than bilateral aid in targeting countries with good rule of law. “Selectivity” is a new phenomenon. During 1984–89, both bilateral and multilateral aid had significant negative relationships with rule of law; by 2000–03 this had shifted to a significant positive relationship for multilateral aid, and a positive but statistically insignificant relationship for bilateral aid.
