Consider a setting where a treatment that starts at some point during a spell (e.g. in unemployment) may impact on the hazard rate of the spell duration, and where the impact may be heterogeneous across subjects. We provide Monte Carlo evidence on the feasibility of estimating the distribution...

When treatments may occur at different points in time, most evaluation methods assume - implicitly or explicitly - that all the information used by subjects about the occurrence of a future treatment is available to the researcher. This is often called the "no anticipation" assumption. In...

We analyze child mortality in Vietnam focusing on gender aspects. Contrary to several other countries in the region, mortality rates for boys are substantially larger than for girls. A large rural-urban mortality difference exists, but much more so for boys than for girls. A higher education...

In duration analysis, the Mixed Proportional Hazard model is the most common choice among practitioners for the specification of the underlying hazard rate. One major drawback of this model is that the value of the frailty term (i.e. unobserved factors) is time-invariant. This paper introduces a...

There is little consensus on how financial aid affects drop-out from or completion of higher education, yet huge amounts are spent on financial aid for higher education. This study adds to the literature by employing variation from a large-scale reform of the Danish grant system to identify the...

This paper investigates the impact of spatially correlated unobservable variables on the refinancing, selling, and default decisions of mortgage borrowers. Virtually the entire mortgage literature acknowledges that borrower specific characteristics, such as culture, education, or access to...
