The Moving to Opportunity (MTO) demonstration assigned housing vouchers via random lottery to low-income public housing residents in five cities. We use the exogenous variation in residential locations generated by the MTO demonstration to estimate the effects of neighborhoods on youth crime and...

Understanding whether criminal behavior is "contagious" is important for law enforcement and for policies that affect how people are sorted across social settings. We test the hypothesis that criminal behavior is contagious by using data from the Moving to Opportunity (MTO) randomized...

We test the hypothesis that criminal behavior is “contagious” – or susceptible to what economists term “endogenous effects” – by examining the extent to which lower local-area crime rates decrease arrest rates among individuals. Using data from the Moving to Opportunity (MTO)...

'Marginal employment', i.e. employment at low working hours and earnings not covered by social security, has been gaining importance in the German economy over the past decade. Using a large newly available panel data set and statistical matching techniques, we analyse the effects of marginal...

Microenterprise programs attempt to help poor people start or strengthen small businesses. Funding and political support has grown rapidly. Is microenterprise a good use of scarce development funds? Unfortunately, most evaluations have been case studies in what not to do. Because benefits and...

Attempts to gauge the depth of outreach of microfinance organizations usually start--and often end--with the measurement of loan size. But just what is loan size? Loan size has at least seven aspects, each of which matters not only for depth of outreach but also for profitability. The aspects...

Cost-benefit analysis (CBA), as a distinctive tool for public investment projects evaluation laying in the portfolio of the governmental authorities, strives to replicate the market in establishing economic standards for the measurement of their success, while the government’s actions are in...

Assessing the value of new medical technologies may require new approaches that take into account a more comprehensive set of parameters than the incremental cost/QALY. It is argued that MCDA can fulfil this role and has the potential to be methodologically superior to the currently used...
