Three models are analyzed using limited dependent variable regression: the impact of T&V on the number of extension contacts with farmers: the effect of extension contact on farmers' knowledge of wheat technology; and the impact of T&V on the adoption of improved wheat technology. The first model analyzes the impact of T&V on the quantity of extension contact and the latter two models analyze the effect on the quantity and quality of extension contact. It is concluded that T&V has increased the quantity but not the quality of extension contact and this, in turn, has increased farmers' knowledge and adoption of technology. However, the overall impacts have been small relative to those observed in a similar area in India. (original)

The analysis provides a conceptual and methodological framework for investigating the expected value of sample information (EVSI), as well as an efficient tool for empirical application. Although a few approximations have been used, the results provide an estimate of EVSI and indicate the need for additional information (original)
