    How can experiments teach us more?

    By - 12 de July de 2011, 8:23 pm

    How can experiments teach us more?Let’s suppose that we wanted to evaluate the broken windows policing theory developed by Kelling and Wilson (1982) and so widely implemented in New York City in the last few decades. Broken windows policing is based on the idea that enforcement of minor crimes should lead to a decrease in the realization of more serious crimes.

    The argument is that neighborhood disorder and vandalism signal a generalized indifference by the State, which in turn encourages more severe criminal behavior; therefore, by reducing minor neighborhood disorder problems, police can effectively reduce major criminality issues.

    So, if we were interested in measuring the impact of broken windows policing on crime, we would probably start thinking of a way of setting an experiment in which a sample of high-crime neighborhoods were randomly assigned to treatment and control groups, with treatment neighborhoods implementing broken windows policing.

    But what if instead, we thought of going the other way around and decided to set an experiment in which we parked a considerable number of used cars with broken windows in half of the neighborhoods and did nothing on the other half? Read more…

    Esther Duflo

    Recently, as part of the 150th anniversary of the Massachusetts Institute of Technology (MIT), renowned economist Esther Duflo made a passionate plea for the importance of measuring and comparing what we know and what we don’t know in order to determine which development policies work and which do not.

    I recommend that you read her presentation and reflect on her message. Read more…

    Five strategies for more effective impact assessments

    Five strategies for more effective impact assessments

    I recently read an interesting article that sets forth strategic options for increasing the effectiveness of impact assessments, not just from a methodological standpoint, but also in terms of implementation.

    The article specifically deals with China and the valuable experience of the Rural Education Action Project of Stanford University, which is collaborating with the Center for Chinese Agricultural Policy.

    Children in Argentina learn more math and science, pilot program shows

    By - 23 de March de 2011, 1:29 pm

    I’m happy to share with you the IDB has launched its 2010 Development Effectiveness Overview (DEO). The 2010 DEO shows that in 2010, 27% of our projects had rigorous impact evaluation plans designed at project approval.

    The DEO reports on key impact evaluations, both ongoing and recently completed, of Bank’s projects in our five institutional priorities.

    Projects include areas such as health in rural areas, early childhood education, neighborhood improvement, renewable energy, access to credit, citizen security, science and technology, tourism and agriculture, among others.

    In this blog we will review some of these evaluations in this and future entries, to show with concrete examples how we learn from our work and how we apply such knowledge.
