ENVIRONMENTAL AND ECONOMIC IMPACTS OF SOIL EROSION AND FERTILITY MINING IN NORTHERN TANZANIA
Provedor de dados: 31
Autores: Nkonya,   Ephraim M.; Barkley,   Andrew P.; Hamilton,   Stephen F.; Bernardo,   Daniel J.
This paper develops a soil conservation model that is relevant to smallholder farmers who apply little or no fertilizer. Empirical results drawn from northern Tanzania imply that, ignoring fertility mining problem in model specification leads to overestimation of profits for farms that apply little or no fertilizer.  The model also shows that, the impact of output price on soil conservation efforts depends on the curvature of the soil erosion function.

Semiparametric Evidence on the Nature of Price Transmission in Tanzanian Maize Markets
Provedor de dados: 31
Autores: Ihle,   Rico; von Cramon-Taubadel,   Stephan.
Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which correspond to major maize production or consumption areas. We propose a novel method for the analysis. The semiparametric vector error-correction model allows the partial impact of the past deviations from price equilibria on current price changes to be potentially nonlinear. The nonparametric estimates of these partial influences suggest that they can be adequately modeled by linear functions.
