Ugandan smallholder farmers produce the nation's major food crop using numerous banana varieties with distinctive attributes, while coping with important biotic constraints and imperfect markets. This empirical context motivates a trait-based model of the agricultural household that establishes...

"Changing agricultural research and extension systems mean that informal mechanisms of information diffusion are often the primary source of information about improved seed and practices for farmers in sub-Saharan Africa. This paper investigates the interactions between gender, social capital...

In this paper we consider the role of variety attributes in an agricultural household model of variety planting decisions. In an application to banana production in Uganda we derive a system of derived demands for a set of available banana varieties. Our empirical model uses a hudle/count data...

This paper explores the reduction of food insecurity in Bolivia, adopting a supply-side approach that analyzes the role of agricultural spending on vulnerability to food insecurity. Vulnerability to food insecurity is captured by a municipal-level composite indicator for all 327 municipalities...

We predict the potential demand of smallholder farmers for genetically transformed varieties of a food crop, the cooking banana of the East African highlands. Farmer demand for planting material is derived in an agricultural household model that accounts for variety traits and missing markets....

A hedonic price model is used to estimate the marginal value function for output characteristics of a subsistence crop in a developing economy. Within the framework of the agricultural household, with non-separable consumption and production decisions, prices reflect the implicit marginal...

In this paper, the heterogeneity of crops is recognized and food commodities are disaggregated into varieties of a crop in order to test whether variety attributes influence the size of the marketed surpluses of selling households. The behavior of semi-subsistence banana producing households in...

Changing agricultural research and extension systems mean that informal mechanisms of information diffusion are often the primary source of information about improved seed and practices for farmers in sub-Saharan Africa. This paper investigates the interactions between gender, social capital and...

We propose an approach to model the derived demand for crop varieties among semi-subsistence farmers in a developing economy, and apply it to smallholder banana producers in Uganda. We model variety planting decisions as being composed of an extensive margin decision to grow a subset of locally...
