Effects on agricultural supply of producer price level and stability with and without goods scarcity: The case of coffee supply in Madagascar

Abstract

This article examines several hypotheses related to influences on the supply of agricultural export products in developing countries. First, it considers the hypothesis that a scarcity of consumer incentive goods so reduces the elasticity of supply to real prices that it becomes negative. Next, it analyses various effects of real price instability on supply, effects that vary according to the availability of consumer goods. Finally, it considers the indirect influence of stabilization schemes on supply, through their effect on the average level of producer prices. The various hypotheses are then tested for the case of coffee supply in Madagascar during the period 1965-84.

Forecasting Volatility In Indian Agri‐Commodities Market

“…The effect of foreign exchange shortage on the price elasticity of supply has been examined in the context of rationed economies (Guillaumont and Bonjean, 1991). Therefore the exchange rates and interest rates were determined as significant factors affecting the US farm economy (Baek and Koo, 2008).…”

“…For the case of regular coffee, some interesting studies where supplies of coffee are analysed are Parikh (1979), and Guillaumont and Bonjean (1991). In the latter, an elasticity of supply of 0.5 is estimated for non-scarcity years.…”

La vulnérabilitééconomique, défi persistant à la croissance africaine

“…Lesétudes sur séries temporelles concernant les effets de la variabilité des prix au producteur se rapportent le plus souventà des produits et des pays spécifiques (par exemple, Araujo, 1995;Behrman, 1968;Guillaumont et Bonjean, 1991;Just, 1974;Lin, 1977). Au niveau macroéconomique, les effets de l'instabilité des prix réels au producteur sur la croissance de la production agricole, sontégalement apparus significativement négatifsà partir d'unéchantillon couvrantà la fois de nombreux pays et plusieurs produits (Boussard et Gérard, 1996;Guillaumont et Combes, 1996; et concernant les effets de l'instabilité des prix réelsà la frontière, Subervie, 2006).…”
