A hedonic approach to estimating the supply of variety attributes of a subsistence crop AgEcon
Edmeades, Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...

A Hedonic Perspective to Estimating a Marginal Value Function for a Subsistence Crop AgEcon
Edmeades, Svetlana.
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 valuation of both consumption and production attributes jointly. Variety-specific crop product farm-gate prices are used in the hedonic analysis. The findings provide guidance for future crop improvement efforts, while revealing those attributes most likely to capture premiums at the market place. Implicit premiums for attribute scarcity are also revealed. Improvements in infrastructure could partially reduce the implicit costs of transportation, leading to higher...

Varieties, Attributes and Marketed Surplus of a Subsistence Crop: Bananas in Uganda AgEcon
Edmeades, Svetlana.
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 Uganda is examined using farm-level survey data collected in 2003. Bananas, the staple crop of the country, are important for meeting immediate consumption requirements and for income generation. The relationship between marketed surpluses and variety attributes is defined theoretically and tested empirically using a semi-parametric censored quantile regression. Inferences are made in two stages to account for differences in the structure of decision-making....

VARIETY DEMAND IN AN INTEGRATED AGRICULTURAL HOUSEHOLD MODEL WITH ATTRIBUTES: IMPLICATIONS FOR EMERGING CROP BIOTECHNOLOGIES AgEcon
Edmeades, Svetlana; Phaneuf, Daniel J.; Smale, Melinda; Renkow, Mitch.
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 framework to examine simaltaneously the likelihood a household has experience with a given variety, and the amount of the variety that is planted. We find that production, consumption, and pest resistance attributes significantly influence planting decisions. These findings have implications for emerging crop biotechnologies.

VARIETY DEMAND WITHIN THE FRAMEWORK OF AN AGRICULTURAL HOUSEHOLD MODEL WITH ATTRIBUTES: THE CASE OF BANANAS IN UGANDA AgEcon
Edmeades, Svetlana; Smale, Melinda; Renkow, Mitch; Phaneuf, Daniel J..
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 the economic association between household preferences for specific variety attributes (yield, disease and pest resistance, and taste), among other exogenous factors, and variety demand, or the extent of cultivation. Six variety demands are estimated in reduced form, each in terms of both plant counts ("absolute" or levels demand) and plant shares ("relative" demand). Two salient findings emerge from the analysis: 1) the determinants of both absolute and relative...
