This study explores smallholder cocoa farmers’ adoption decisions of agrochemical inputs in the Ghanaian cocoa industry using farm-level data collected from a sample of 838 farm households in four cocoa producing regions. Multivariate probit and Tobit models were used to examine the determinants of agrochemical inputs adoption and the extent of adoption, respectively. The result of the study showed that agrochemical management practices are complementary and thus the adoption of an agrochemical input is conditional on the adoption of others. Different household characteristics, household assets, institutional variables, and the perception of soil fertility status and the incidence of pests and diseases influence the adoption of individual agrochemical inputs. Furthermore, the result of the study showed that intensity (or extent) of agrochemical adoption (measured as farmers’ expenditure on agrochemicals) is also influenced by some socioeconomic and institutional variables such as extension services and fa...read more

Semiparametric instrumental variable estimation of treatment response models
TL;DR: In this paper, a new class of instrumental variable (IV) estimators for linear and nonlinear treatment response models with covariates is introduced, which allows the researcher to construct estimators that can be interpreted as the parameters of a well defined approximation to a treatment response function under functional form misspecification.
