Agricultural supply response and poverty in Mozambique
This paper identifies the key causal factors behind farmers’ marketing decisions in Mozambique. A two-step decision making process is modelled. Farmers decide, first, whether or not to participate in the market and, second, how much to market. The model is estimated using a Heckman switching regression approach. Marginal effects are calculated for the poor and the nonpoor and broken down into a...
متن کاملTransactions Costs and Agricultural Household Supply Response
We develop and estimate a model of supply response when transactions costs create a situation where some producers buy, others sell, and others do not participate in markets. We present two rationales for why producing households may have different relationships to the market: proportional and fixed transactions costs. Using data on Mexican corn producers, we estimate an empirical model that al...
متن کاملWhy Are Estimates of Agricultural Supply Response so Variable?
Estimates of the response of agricultural supply to movements in expected price display curiously large variation across crops, regions and time periods. We argue that this anomaly may be traced, at least in part, to the statistical properties of the commonly-used econometric estimator, which has infinite moments of all orders and may have a bimodal distribution. We propose an alternative minim...
متن کاملPrices and Production: Agricultural Supply Response in Fourteenth-century England
This paper challenges the growing consensus in the literature (Stone, 2005; Dodds, 2007) that medieval English peasants and manorial managers were price responsive in their production decisions. Using prices of and acreages planted with wheat, barley, and oats on 49 manors held by the bishop of Winchester from 1349-70, we estimate price elasticities of supply for each grain in aggregate and on ...
متن کاملA Collaborative Model for Agricultural Supply Chains
This paper presents a collaborative model for agricultural supply chains that supports negotiation, renegotiation, coordination and documentation mechanisms, adapted to situations found in this kind of supply chain – such as return flows and composite regulations. This model comprises basic building blocks and elements to support a chain’s dynamic execution. The model is supported by an archite...
