Improving the speed of adoption of agricultural technologies and farm performance through farmer groups: evidence from the Great Lakes region of Africa

The article examines the effect of membership in farmer groups (MFG) on adoption lag of agricultural technologies and farm performance in Burundi, the Democratic Republic of Congo and Rwanda. We use duration and stochastic production frontier models on farm household data. We find that the longer the duration of MFG, the shorter the adoption lag and much more so if combined with extension service delivery. Farmer groups function as an important mechanism for improving farm productivity through reduced technical inefficiency in input use. We discuss policy implications under which farmer groups are a useful channel to reduce adoption lag, and the means through which improved farm performance can be achieved.     

Entrepreneurial beacons: The Yale endowment,run‐ups,and the growth of venture capital

Research summary : This article investigates the social context of entrepreneurship in organizational sectors. Prior research suggests that firm foundings are driven by collective patterns of activity—such as patterns of prior foundings in a given sector. Building on research on social salience and signals, we consider the influence of singular sector‐level triggers, which we call entrepreneurial beacons. We argue that the actions or outcomes of single, salient organizations attract and motivate entrepreneurs, thus increasing the rate of foundings. We test this logic by examining the impact of the Y ale U niversity endowment's investment choices and of venture‐capital‐backed IPO run‐ups on venture‐capital foundings between 1984 and 2011. We find support for the existence and influence of beacons and outline boundary conditions for their effects . Managerial summary : What leads entrepreneurs to found new companies in nascent sectors? In contrast to prior research, which emphasizes patterns of activity, we argue that entrepreneurial activity can sometimes be driven by the actions of a singular trigger—what we call an entrepreneurial beacon. We examine the influence of two such beacons, Y ale U niversity's endowment investments and exceptional venture‐capital‐backed IPO run‐ups, on the founding of new venture‐capital firms over a 28‐year period. We find that Y ale's increased allocations to the venture‐capital asset‐class has a significant influence on the founding of new venture‐capital firms, while exceptional venture‐capital‐backed IPO run‐ups only influence venture‐capital foundings under certain conditions. Overall, we offer an explanation for heretofore anecdotal accounts of certain organizations or events that appear to have an outsized influence on entrepreneurial activity .

Capital Mobility in Open OLG Models of Neoclassical Growth

This paper explores whether the international mobility of physical and/or financial capital is essential for productive efficiency in each of three open OLG models of neoclassical growth that vary in terms of dimensional attributes. A tradeoff between capital mobility requirements and dimension has previously been established by example where, ceteris paribus , neither form of capital mobility is required with three productive sectors, only physical capital mobility is required with two sectors, and both forms of mobility are required with a single sector. This paper reconsiders that tradeoff using a generalization of the production and utility functions which introduces the potential for specialization along the transition path—an event which would imply inconsistent capital mobility requirements along the growth path for models with fixed dimension. Conditions are established under which the tradeoff between capital mobility requirements and dimension remains valid.     

The Political,Economic, and Social Aspects of Katrina

In this paper, we examine the resiliency of community recovery after a natural disaster. We argue that a resilient recovery requires robust economic/financial institutions, political/legal institutions, and social/cultural institutions. We explore how politically and privately created disaster preconditions and responses have contributed to or undermined institutional robustness in the context of the Gulf Coast's recovery after Hurricane Katrina. We find that where postdisaster resiliency has been observed, private-sector responses contributing to the health of these institutional arenas are largely responsible. Where postdisaster fragility and slowness has been observed, public-sector responses contributing to the frailty of these institutional arenas are largely the cause. In other words, we engage in a comparative institutional analysis of civil society, entrepreneurial commercial society, and government agencies and political actors in the wake of a natural disaster.     

How 'modern' is the modern apprenticeship?

Despite the fact that some sectors of industry are facing major skills shortages, the Scottish labour market continues to be characterised by occupational segregation and a large disparity between the wages of women and men. The concentration of individuals in occupations and training based on their gender effectively restricts the pool of potential recruits to industry and is unlikely to make the best use of human capital. Moreover, it obstructs the pursuit of gender equality by reinforcing the gender pay gap and restricting individual career choices. This paper reports on the government's flagship training policy, the Modern Apprenticeship programme, from a gender perspective. It concludes that, ten years on from its introduction, the scheme represents something of a 'missed opportunity' to tackle occupational segregation and its deleterious effects in the wider economy and in society at large. It is recommended that the government and organisations involved in the development and delivery of Modern Apprenticeships adopt a more conscious and cohesive approach to promoting non-traditional choices at the vocational level.     

Testing subgame perfection apart from fairness in ultimatum games

We present an experiment designed to separate the two commonplace explanations for behavior in ultimatum games—subjects’ concern for fairness versus the failure of subgame perfection as an equilibrium refinement. We employ a tournament structure of the bargaining interaction to eliminate the potential for fairness to influence behavior. Comparing the results of the tournament game with two control treatments affords us a clean test of subgame perfection as well as a measure fairness-induced play. We find after 10 iterations of play that about half of all non-subgame-perfect demands are due to fairness, and the rest to imperfect learning. However, as suggested by models of learning, we also confirm that the ultimatum game presents an especially difficult environment for learning subgame perfection.
