Second-Stage Stratification in India’s Labour Force Surveys: A Simulation Study∗

Abstract
In this paper, we examine the utility of second-stage stratification within the first-stage units (FSUs) of large-scale sample surveys, focusing on India’s official labour force surveys, namely the NSSO Employment-Unemployment Survey 2011-12, the Labour Bureau Employment-Unemployment Survey 2013 – 14, and the Periodic Labour Force Survey 2022 – 23. These three surveys stratify households within the FSU in different ways, and we examine the implications of these choices for the statistical precision of the resulting estimates. Using Monte Carlo simulations on FSUs constructed from PLFS 2022 – 23 unitlevel data, we estimate the variance of each design across three labour market outcomes: labour force participation rate (LFPR), unemployment rate (UR), and labour income. Our primary finding is that the household-level stratification designs employed in these surveys do not necessarily improve precision. For labour force participation and unemployment, simple random sampling outperforms stratification in most FSUs. In general, gains depend critically on the correlation between the stratification variable and the outcome of interest. We propose an alternative education-based scheme that combines lower secondary (10th pass) and graduate attainment. This design raises the median efficiency gain over the PLFS by about 14% for unemployment and 17% for income. We conclude with some reflections on the factors that are relevant to the choice of stratification design.

Estimating the productivity gap between organised and unorganised small-scale units in India’s manufacturing sector

Abstract
Small manufacturing firms are considered to be engines of growth and job creation. While most research on small firms focuses on formal sector units, in India informal sector units far outnumber the formal. This is true even for manufacturing units employing 5 to 49 workers, which constitute only 5% of all unorganised units, but in absolute numbers are nine times more numerous than organised units in the same size class. Such firms have the potential to contribute to structural transformation but their capacities vis-a-vis formal firms are not well understood. To address this, the researchers create a unit-level dataset combining Annual Survey of Industries data for organised (formal) units with the National Sample Survey data on unorganised (informal) units. They also discuss problems involved in this exercise and some ways to deal with them. They find that matching organised and unorganised units on observable characteristics reduces the labour productivity differences between them to around 25 percent. The researchers discuss some policy implications of their results.

Pandemic, informality, and vulnerability- Impact of COVID-19 on livelihoods in India
in Azim Premji University

Abstract
We analyze findings from a large-scale survey of around 5000 respondents across 12 states of India to study the impact of COVID-19 pandemic containment measures (lockdown) on employment, livelihoods, food security and access to relief measures. We find a massive increase in unemployment, an equally dramatic fall in earnings among informal workers, large increases in food insecurity, depletion of savings and patchy coverage of relief measures. Two-thirds of our respondents lost work. The few informal workers who were still employed during the lockdown experienced more than a fifty percent drop in their earnings. Even among regular wage workers, half received either no salary or reduced salary during the lockdown. Almost eighty percent of surveyed households experienced a reduction in their food intake and a similar percentage of urban households did not have enough money to pay next month’s rent. We also use a set of logistic regressions to identify how employment loss and food intake varies with individual and household level characteristics. We find that migrants and urban Muslims are significantly worse off with respect to employment and food security. Among employment categories, self-employed workers were more food secure. The Public Distribution System (PDS) system was seen to have the widest reach among social security measures. However, even under PDS, 16 percent of vulnerable urban households did not have access to government rations. Further, half of the respondents reported not receiving any cash transfers (state or central). We conclude that much more is needed in the way of direct fiscal support that has been announced thus far by state and central governments in India.
