Audit Selection under Weak Fiscal Capacity

Measuring the Effect of Technological Improvements and Compliance Nudges on Property Taxes

Evidence from a field experiment in Senegal Issue: Rapid urbanization and the growth of real estate developments in low-income countries has increased the potential of property tax as a source of untapped domestic resource mobilization. Unfortunately, in most developing countries, property tax…

Constructing Compliance: Reducing Tax Evasion Among Market Traders in Ghana

Can Transparency Improve Preferences and Norms in the Public Sector?

Issue:  Political norms and citizen preferences could be key enablers of the poor quality of public services in developing countries. Politicians may, for example, deprioritize public service delivery improvements because citizens prefer elected officials that offer them private benefits, including government jobs or…

Recruitment, Effort, and Retention Effects of Performance Contracts for Civil Servants

Drawing on experimental evidence from Rwanda primary schools Issue: Skilled and intrinsically motivated public sector employees are critical to state capacity and the provision of key services, including education. Yet the capability to recruit, motivate, and retain this profile of civil servants…

Bottom-Up Transparency Initiatives to Reduce Corruption

Issue: Transparency interventions frequently rely on a top-down approach in which a policymaker or external entity demands information about activity in a particular sector. Bottom-up transparency interventions differ by offering citizens the opportunity to directly initiate efforts to improve public goods or services….

Governance Capacity and Political Selection

Issue: The digitization of key government services — in this case, India’s National Rural Employment Guarantee Scheme — can streamline public service delivery and reduce the ability of politicians to misappropriate state funds. Political officials face challenges if they lack sufficient…

Politician Entry, Selection, and Performance in Sierra Leone

Is Knowledge Power? Civics Training, Women’s Political Representation, and Local Governance in India

Institutional Reform and de facto Women’s Rights

Issue:  In many socially-conservative settings, legal protections and provisions have frequently outpaced how administrators enforce these rules. In Pakistan, for example, government officials often use their own judgement and respond to local concerns when carrying out functions critical to women’s rights, including…

Community Policing and Public Trust: A Field Experiment in Uganda

Issue:  Use of excessive force has diminished trust between citizens and law enforcement in many parts of Uganda. In an effort to improve this dynamic, the state is revisiting a “homegrown” model of community-policing that increases police presence through local patrols and community…

Community Policing and Public Trust: A Field Experiment in Colombia

Issue: Medellín, Colombia is a metropolitan area of more than 3.7 million people, and a place with long history of violence, pressing threats to citizen security, and improving—but still fragile—police-community relations. Lack of trust in the police and the consequent lack of…

Reforming Police Practices in India

Issue: The Indian state of Madhya Pradesh’s police force has a low officer to citizen ratio with multiple vacant positions, and a lack of representation of women in their ranks. Efforts have begun to make police forces more public-oriented, but…

Improving the Effectiveness of Labor Courts through Information and Conciliation

Labor courts are essential for the workings of well-functioning labor markets. However, the courts in many lower-middle and low-income countries are rendered dysfunctional by large backlogs in resolving cases, corruption, low settlement rates, poor enforcement, and limited access to justice….

Further information

Overall this research looks at the pressing need to improve the responsiveness and functionality of public and private institutions, which has motivated numerous governments and donors to actively support governance-promoting activities – from citizen information campaigns, to bureaucrat incentives and enhanced personnel policies. Many of these investments are producing gains for citizens in need of effective state services and economic opportunities. However, far too few of these initiatives have been linked to rigorous evaluations that allow stakeholders to identify what specifically is effective and show how a model might be replicated or improved. Moreover, few of the evaluations that do exist have been designed to generate conclusions beyond the specific contexts within which they were implemented.

The Scientific Committee for the RCTs is chaired by Ted Miguel from the CEGA at the University of California, Berkeley in close partnership with François Bourguignon, Research Co-Director of EDI. All research under this area is conducted in partnership with government or public institutions.
