Purpose

This paper aims to understand the causes of low adoption of hybrid rice technology. The paper also assesses the impact of adoption of hybrids and modern varieties on crop yield, vis-à-vis the old or traditional varieties.

Design/methodology/approach

Using unit-level data from a large-scale survey of farm households (19,877 paddy cultivators), the authors applied multi-nomial regression method to understand the factors for adoption of hybrid rice and instrumental variable method of regression to estimate its impact.

The gendered effects of climate change: Evidence from droughts in rural India

Submitted by Ishita Datta on

In contrast to previous research, which suggests that women's employment rises during negative household income shocks in low-income economies, the findings in this study, reveal that, despite an increased likelihood of seeking work due to aggregate income shocks, women's employment may not rise if their labor mobility is constrained. Moreover, the impact of climatic shocks may be enduring. The cross-sectional analysis indicates that gender disparities in non-farm employment and migration are more pronounced in villages exposed to higher risks from rainfall variability.

AbstractEmployment income data are coarsened as a result of questionnaire design. In the previous chapter we saw that Statistics South Africa (SSA) ask two employment income questions: an exact income question with a showcard follow-up. In public-use datasets, this results in two income variables: a continuously distributed variable for exact income responses and a categorical variable for bounded income responses with separate categories for nonresponse. It is the task of the researcher to then generate a single income variable that effectively deals with this mixture of data types.
