The American Single Mother

The American Single Mother

Women of Color Policy Network

Across race and age groups, education is the single greatest predictor of single-motherhood in America. This policy brief offers a profile of the American single woman mother, contemporary population trends, and the economic security of this growing demographic.

Income and Poverty in Communities of Color

Income and Poverty in Communities of Color

Women of Color Policy Network

The U.S. Census Bureau’s recent statistics on income highlight the need for increased social supports for working families, the allocation of additional funds to create quality jobs with good wages, and the development of bold and targeted policies to help individuals and groups disproportionately impacted by the recession recover.

Microfinance Games

Microfinance Games
American Economic Journal: Applied Economics 2(3): 60-95, July 2010.

Gine, Xavier, Pamela Jakiela, Dean Karlan, and Jonathan Morduch

Microfinance banks use group-based lending contracts to strengthen borrowers' incentives for diligence, but the contracts are vulnerable to free-riding and collusion. We systematically unpack microfinance mechanisms through ten experimental games played in an experimental economics laboratory in urban Peru. Risk-taking broadly conforms to theoretical predictions, with dynamic incentives strongly reducing risk-taking even without group-based mechanisms. Group lending increases risk-taking, especially for risk-averse borrowers, but this is moderated when borrowers form their own groups. Group contracts benefit borrowers by creating implicit insurance against investment losses, but the costs are borne by other borrowers, especially the most risk averse. 

Hospital Performance, the Local Economy, and the Local Workforce: Findings from a US National Longitudinal Study

Hospital Performance, the Local Economy, and the Local Workforce: Findings from a US National Longitudinal Study
PLoS Med 7(6): e1000297. doi:10.1371/journal.pmed.1000297

Blustein, J., Borden, W.B., Valentine, M.


Background: Pay-for-performance is an increasingly popular approach to improving health care quality, and the US government will soon implement pay-for-performance in hospitals nationwide. Yet hospital capacity to perform (and

improve performance) likely depends on local resources. In this study, we quantify the association between hospital performance and local economic and human resources, and describe possible implications of pay-for-performance for socioeconomic equity.

Methods and Findings: We applied county-level measures of local economic and workforce resources to a national sample of US hospitals (n = 2,705), during the period 2004–2007. We analyzed performance for two common cardiac conditions (acute myocardial infarction [AMI] and heart failure [HF]), using process-of-care measures from the Hospital Quality Alliance [HQA], and isolated temporal trends and the contributions of individual resource dimensions on performance, using multivariable mixed models. Performance scores were translated into net scores for hospitals using the Performance Assessment Model, which has been suggested as a basis for reimbursement under Medicare’s ‘‘Value-Based Purchasing’’ program. Our analyses showed that hospital performance is substantially associated with local economic and workforce resources. For example, for HF in 2004, hospitals located in counties with longstanding poverty had mean HQA composite scores of 73.0, compared with a mean of 84.1 for hospitals in counties without longstanding poverty (p,0.001). Hospitals located in counties in the lowest quartile with respect to college graduates in the workforce had mean HQA composite scores of 76.7, compared with a mean of 86.2 for hospitals in the highest quartile (p,0.001). Performance on AMI measures showed similar patterns. Performance improved generally over the study period. Nevertheless, by 2007—4 years after public reporting began—hospitals in locationally disadvantaged areas still lagged behind their locationally advantaged counterparts. This lag translated into substantially lower net scores under the Performance Assessment Model for hospital reimbursement.

Conclusions: Hospital performance on clinical process measures is associated with the quantity and quality of local economic and human resources. Medicare’s hospital pay-for-performance program may exacerbate inequalities across regions, if implemented as currently proposed. Policymakers in the US and beyond may need to take into consideration the balance between greater efficiency through pay-for-performance and socioeconomic equity.

Economic Development Impacts of High-speed Rail

Economic Development Impacts of High-speed Rail
RCWP 10-007 June, 2010

Levinson, David

High-speed rail lines have been built and proposed in numerous countries throughout the world. The advantages of such lines are a higher quality of service than competing modes (air, bus, auto, conventional rail), potentially faster point-to-point times depending on specific locations, faster
loading and unloading times, higher safety than some modes, and lower labor costs. The disadvantage primarily lies in higher fixed costs, potentially higher energy costs than some competing modes, and higher noise externalities. Whether the net benefits outweigh the net costs is an empirical question that awaits determination based on location specific factors, project costs, local demand, and network effects (depending on what else in the network exists). The optimal network design problem is hard (in the mathematical sense of hard, meaning optimal solutions are hard to find because of the combinatorics of the possible different network configurations), so heuristics and human judgment are used to design networks.


Minimum Parking Requirements, Transit Proximity and Development in New York City

Minimum Parking Requirements, Transit Proximity and Development in New York City
RCWP 10-004 Furman Center for Real Estate and Urban Policy

McDonnell, Simon, Josiah Madar and Vicki Been

New York City policymakers are planning for a city of over 9 million residents by 2030, a large increase from today. A central goal of City officials is to accommodate this increase while simultaneously improving the City’s overall environmental performance, addressing externalities arising from traffic congestion and providing increased access to affordable housing. The requirement in the City’s zoning code that new residential construction be accompanied by a minimum number of off-street parking spaces, however, may conflict with this goal. This paper combines a theoretical discussion of parking requirements in New York City with a quantitative analysis of how they relate to transit and development opportunity. It draws direct relations between minimum parking requirements with the rise in housing prices and the reduction of density.

Half the World is Unbanked

Half the World is Unbanked
Financial Access Initiative Report, October 2009. Feature in McKinsey Quarterly, March 2010

Jonathan Morduch, Alberto Chaia, Aparna Dalal, Tony Goland, Maria Jose Gonzalez, and Robert Schiff

Limited information on the size and nature of the global population using financial services limits policy makers’ abilities to identify what’s working and what’s not, and it limits financial services providers’ abilities to identify where the opportunities lie and where they could learn from current successes.

A new report, “Half the world is unbanked,” provides an improved estimate of the size and nature of the global population that does and does not use formal (or semiformal) financial services.

This paper builds on a data set compiled from existing cross-country data sources on financial access and socioeconomic and demographic characteristics to generate an improved estimate of the size and nature of the global population that does and does not use formal (or semiformal) financial services.
