We test whether early Affordable Care Act (ACA) Medicaid expansions in Connecticut (CT), Minnesota (MN), California (CA), and the District of Columbia (DC) affected SSI applications, SSI and DI awards, and the number of SSI and DI beneficiaries. We use a difference-in-difference (DD) approach, comparing SSI/DI outcomes pre and post each early Medicaid expansion ("Early Expanders") to SSI/DI outcomes in states that expanded Medicaid in January 2014 ("Later Expanders"). We also use a synthetic control approach, in which we examine SSI/DI outcomes before and after the Medicaid expansion in each Early Expander state, utilizing a weighted combination of Later Expanders as a comparison group. In CT, the Medicaid expansion is associated a statistically significant, 7 percent reduction in SSI beneficiaries; this finding is consistent across the DD and synthetic control methods. For DC, MN and CA, we do not find consistent evidence that the Medicaid expansions affected disability-related outcomes.

Policy makers in developing countries, including India, are increasingly sensitive to the links between spatial transformation and economic development. However, the empirical knowledge available on those links is most often insufficient to guide policy decisions. There is no shortage of case studies on urban agglomerations of different sorts, or of benchmarking exercises for states and districts, but more systematic evidence is scarce. To help address this gap, this paper combines insights from poverty analysis and urban economics, and develops a methodology to assess spatial performance with a high degree of granularity. This methodology is applied to India, where individual household survey records are mapped to "places" (both rural and urban) below the district level. The analysis disentangles the contributions household characteristics and locations make to labor earnings, proxied by nominal household expenditure per capita. The paper shows that one-third of the variation in predicted labor earnings is explained by the locations where households reside and by the interaction between these locations and household characteristics such as education. In parallel, this methodology provides a workable metric to describe spatial productivity patterns across India. The paper shows that there is a gradation of spatial performance across places, rather than a clear rural-urban divide. It also finds that distance matters: places with higher productivity are close to each other, but some spread their prosperity over much broader areas than others. Using the spatial distribution of this metric across India, the paper further classifies places at below-district level into four tiers: top locations, their catchment areas, average locations, and bottom locations. The analysis finds that some small cities are among the top locations, while some large cities are not. It also finds that top locations and their catchment areas include many high-performing rural places, and are not necessarily more unequal than average locations. Preliminary analysis reveals that these top locations and their catchment areas display characteristics that are generally believed to drive agglomeration economies and contribute to faster productivity growth.

Institutional constraints and weak capacity often hamper the ability of local governments in developing countries to steer urbanization. As a result, there are not enough cities to accommodate an unabated rural-urban migration and many of those that exist are messy, sprawling, and disconnected. The flipside is the emergence of entire cities-- more than gated communities or industrial parks-- led in whole or in part by private actors. To date, little systematic research has been conducted on the conditions that are necessary for such unusual entities to emerge, on the roles played by private actors, or on the consequences for efficiency and equity. This publication aims to fill this gap. Using an analytical framework that draws on urban economics and political science, it includes inventories of private cities in the Arab Republic of Egypt, India, Indonesia, and Pakistan and provides structured reviews of 14 outstanding examples across all developing regions. Nongovernment actors turn out to be diverse-- they include not only major companies and large developers but also business associations, civil society organizations, and even foreign countries. The way local governments interact with these nongovernment actors varies as well, from deliberate neglect to joint ventures. Private actors take on some-- but not all-- local government functions, while at times embracing unconventional roles. And while private cities tend to be economically successful, they can lead to environmental degradation, social segregation, and even institutional secession. Increasing the capacity of local governments in developing countries will take time. There is a case for selectively tapping into the comparative advantage of significant private actors while actively using policy tools to avoid the potential shortcomings. In the spirit of a public-private partnership for urbanization, land value capture would be at the center of this approach.
