Livelihoods are changing rapidly in rural areas. Measuring and categorizing peoples’ labor activities in relation to the agricultural sector is important for understanding income earning opportunities and designing effective policy. Conventional data collection methods ask about individuals’ main work activities over the past year. Descriptions are recorded in the field, postcoded, and eventually categorized. This approach is costly to collect, fatiguing for respondents, and may create distortions. We show that a more direct approach, asking respondents to categorize their major work activities themselves, provides similar resulting data despite some caveats and lessons for best enumeration practices. We compare these main activities to a series of yes/no questions about participation in a set of specific work tasks. We find a 12% incidence of “missing” work, whereby individuals who reported participation in at least one but did not have any recorded major activities. Looking by sector of work, women and youth are disproportionately more likely to have agricultural contributions “missed,” while we find no corresponding bias in undercounting of non-agricultural work. Finally, we test the effect of randomly positioning the task-based questions before the listing of major activities but do not find significant effects on the number or type of activities reported.

This is an empirical study of labour supply and demand issues in semi-arid developing agriculture, explicitly accounting for the presence of the production risk that impinges on farm decision making. It further analyses and empirically tests for the interdependence between the production risk that farmers face in the process of self-cultivation and the labour market risk (or uncertainty of finding off-farm work) that they face when operating in the local labour market. The empirical estimation is based on a unique and relatively comprehensive panel data set relating to a sample of rural households operating in the Indian semi-arid tropics. The presence of unemployment in the local labour market is acknowledged by the formulation and estimation of a disequilibrium model of the labour market, supplementing the partial analyses of labour supply and demand. A comparison of the results of the alternative models, partial and simultaneous, allows a more complete analysis of the issues involved.

We show analytically and empirically that non-classical measurement errors in the two key variables in a hypothesized relationship can bias the estimated relationship between them in any direction. Furthermore, if these measurement errors are correlated, correcting for either one alone can aggravate bias in the parameter estimate of interest relative to ignoring mismeasurement in both variables, a ‘second best’ result with implications for a broad class of economic phenomena of policy interest. We illustrate these results empirically by demonstrating the implications of mismeasured agricultural output and plot size for the long-debated (inverse) relationship between size and productivity.
