Micro- and small firms lack access to external finance and the labour market so that they are vulnerable to family hardships experienced by the owners such as deaths or sickness of family members. The literature is thin on how these firms cope with family hardships, in particular on whether owners’ access to social health insurance helps. We examine whether a social health insurance in Indonesia, Askeskin, protects owners of micro- and small firms against family hardships. We find some evidence Askeskin reduces the adverse effects of recent deaths in the family, outpatient care, and traffic accidents on net profits; Askeskin also protects the firms’ assets against owners’ outpatient care need. Social health insurance may, therefore, improve micro- and small firms’ survival, which (because most people in developing countries’ labour markets work in micro- and small firms) helps governments’ efforts to eradicate poverty.

We examine the effects of having English as a medium of instruction on labor market outcomes later in life. We exploit an exogenous variation in mediums of instruction induced by the government of Malaysia’s decision to discontinue English-medium public schools and phase them out with Malay-medium public schools in 1970, which fits a fuzzy regression discontinuity design. We find some evidence that having English as a medium of instruction improves labor market outcomes. We explore some mechanisms through which mediums of instruction matter: We find having English as a medium of instruction improves English proficiency, especially reading and writing skills, and increases educational attainment, which in turn increase earnings and improve employability. The evidence is, however, rather weak, if we use robust data-driven inferences in the regression discontinuity design.

This paper reevaluates the effect of a tenancy reform, popularly known as Operation Barga, on agricultural productivity in West Bengal, India. We employ a transparent empirical strategy based on synthetic control. We focus on the varying intensity of Operation Barga across West Bengal districts by comparing the districts’ agricultural productivity with that of counterfactual districts using the synthetic control approach. Concerns over agro-climatic diversity and the recorded history of land reforms were also addressed while creating counterfactual districts. We find robust empirical evidence of a negligible effect on agricultural productivity growth. Next, we consider a theoretical framework to estimate the potential gains from Operation Barga in light of several types of sharecroppers. Consistent with the empirical findings, we conclude that the capacity of Operation Barga to enhance agricultural productivity is heavily constrained by the heterogeneity of sharecroppers in terms of wealth and livelihood structure.

We examine the effects of corporate social responsibility (CSR) activities on the values of firms. Using a non-parametric regression discontinuity design, exploiting a natural experiment induced by India’s Companies Act 2013, we find investors devalue the stocks of firms that do CSR activities by 2-5%, which suggests investors are unwilling to pay for CSR activities.

This paper examines the effects of trade on economic growth and growth volatility. Using the 1967-1975 closure of the Suez Canal as an instrument for trade, I find that trade leads to higher economic growth, and lower probability of recession or economic slowdown. There is no evidence that trade reduces growth volatility, however.
