Book Description
DAHBSIM is a dynamic, bio-economic model of agricultural households that was designed to be applied to a rural, developing country-setting, for the purpose of addressing questions around the biophysical constraints to on-farm agricultural productivity, and the whole-farm implications of alternative strategies to sustainable agricultural intensification. The model links socio-economic and biophysical aspects, in order to better illustrate the environmental and human welfare implications of different agricultural production practices, as they are influenced by policy-driven changes in prices of inputs or outputs, or by changes in the physical environment.

Book Description
A model addressing agricultural responses to public interventions is described. The model is confined to the short run, and it allows an assessment of the policy significance of changes in five variables that are exogenous to the household. The first variable is the price of the main agricultural output, emphasizing the elasticities of both output and market surplus; the second is the wage rate for agricultural labor, focusing on the elasticities of household labor supply and demand for hired labor; the third is the size of the family labor force, which is essential for estimating shadow wage rates; the fourth is the number of dependents, in order to permit an assessment of family planning policies; and the final variable is technology. The main features of the model are the role of the labor market, household production, household consumption, and the aggregate effect of household responses. Applicaton of the model to the Muda River Valley demonstrates that it is appropriate to a number of policy isues ranging from output price intervention to technological innovaton. Specifically, the model indicates that the economic cost of rural to urban migration is small when compared to the marginal productivity of the migrant before his departure.

Book Description
A substantial amount of the literature has reported on the impact of access to credit on technology adoption, and many studies find that credit has a positive impact on adoption. However, most existing studies have failed to explicitly measure and analyze the amount of credit that farm households are able to borrow and whether they are credit constrained or not. They overlooked the fact that credit access can be a panacea for non-adoption only if it is targeted at households that face binding liquidity constraints. Guided by the frame work of a household model under credit market failure, this paper aims at investigating the impact of access to credit on the adoption of hybrid maize among households that vary in their credit constraints. The data used in the study is from Malawi collected by the International Food Policy Research Institute (IFPRI). Using the direct elicitation approach, households are classified into constrained and unconstrained regimes. We start by estimating the probability of being credit constrained, followed by an estimation of the impact of access to credit for the two categories of households (credit constrained and unconstrained), while accounting for selection bias. The impact of access to credit is estimated using a switching regression in a Double-Hurdle model. Results reveal that while access to credit increases adoption among credit constrained households, it has no effect among unconstrained households. Results also show that factors that affect adoption among credit constrained households are different from those that that affect adoption among unconstrained household. Landholding size, for example, has opposite effects on adoption in the two regimes of households. The policy implication is that microfinance institutions should consider scaling up their credit services to ensure that more households benefit from it, and in so doing maize adoption will be enhanced.
