In this paper, a model of the nitrogen cycle in the soil is incorporated in a Computable General Equilibrium (CGE) model of the Tanzanian economy, thus establishing a two-way link between the environment and the economy. For a given level of natural soil productivity, profit-maximising farmers choose input levels — and hence production volumes — which in(More)
Despite the widespread occurrence of humanitarian emergencies such as epidemics, earthquakes, droughts, floods and violent conflict and despite the significant financial resources devoted to humanitarian assistance, systematic learning from such interventions using rigorous theory-based impact evaluations are very rare. The objective of this paper is(More)
We study an important mechanism underlying employee referrals into informal low skilled jobs in developing countries. Employers can exploit social preferences between employee referees and potential workers to improve discipline. The profitability of using referrals increases with referee stakes in the firm, and, in most cases, with the strength of the(More)
This paper expands Basu and Van’s (1998) model of child labour to include educational provision, school infrastructure and publicly employed teachers who allocate their time between o¢ cial duties and the provision of private tutoring. While increasingly common both in rich and poor countries, the problems with public employees taking on such double roles(More)
We investigated if low level laser irradiation (LLLI) can reduce muscular fatigue during tetanic contractions in rats. 32 male Wistar rats were divided in 4 groups receiving LLLT doses of 0 (control group), 0.5, 1.0 and 2.5 J/cm2. Irradiation lasted 32, 80 and 160 seconds respectively with a fixed power density of 31.25 mW/ cm2. The total energy doses were(More)
This document distills “Understanding Replication, A Historical and Conceptual Guide” by Vegard Iversen and Richard Palmer-Jones (IPJ) for researchers planning internal replications of previous impact evaluations. Parts of the following are taken verbatim from IPJ’s current working paper and the 3ie Replication Program Document. Please note that this is the(More)
We test core theories of the household using variants of a public good game and experimental data from 240 couples in rural Uganda. Spouses do not maximise surplus from cooperation and realise a greater surplus when women are in charge. This violates assumptions of unitary and cooperative models. When women control the common account, they receive less than(More)
