Abstract
We report the impacts of a randomized housing quality improvement intervention among Indian migrant workers. Despite modest improvements in conditions, respondents experienced a decline in satisfaction and a large increase in psychological distress as a result of treatment. In contrast, residents who faced the same treatment-induced variation in living conditions as the original sample, but who arrived after treatment had already been initiated, had increased satisfaction. Impacts on turnover echo these patterns. We interpret this as evidence of reference dependence: residents who were primed to expect larger-than-realized improvements in living conditions suffered utility losses, while exposed but unprimed residents experienced gains.

Experimental Details

Interventions

Intervention(s)
Our intervention is a change in the management of hostels for migrant garment workers in Bengaluru, India. At baseline, the hostels we study were employer-managed, and living conditions in these hostels were characterized negatively. In two phases, hostel management was transferred to a local NGO specializing in women’s empowerment with specific experience managing migrant worker hostels. The NGO then took a series of measures to improve sanitation, security, and access to utilities in these hostels.

Experimental Design

Experimental Design
We investigate whether the changeover in management has improved hostel conditions and, if so, how improved living conditions in hostels affect migrant workers’ satisfaction and turnover. In order to estimate causal treatment effects, the partner firm rolled out the management changeover across factories in two phases, with factories (and their corresponding hostels) assigned randomly to either the first or the second phase of the changeover. Our research design takes advantage of the gap between phases I and II, during which treatment hostels were under the new (NGO) management while control hostels were still managed by the employer. Near the end of this gap, we conducted a survey among a random sample of workers from all hostels to study differences in satisfaction and subjective well-being. At the same time, we administered a blinded enumerator evaluation survey for all 80 hostels in order to form "objective" measures of changes in housing quality.
