Resumen
Descripción
The paper presents an empirical investigation of the supply of maize and tobacco for
commercial agriculture in Zimbabwe. The error correction model, which employs the concept of
cointegration to avoid spurious regressions, is used in the analysis. The factors affecting percentage area
planted to maize were shown to be expected real maize price, real price of tobacco, real price of fertilizer
and government intervention. The factors affecting percentage area planted to tobacco were shown to be real
price of tobacco, expected real price of maize and institutional factors. The own price elasticity for maize
was 1.44 and 1.76 in the short and the long run, respectively, for tobacco these were 0.28 and 1.36 in the
short and long run respectively.
