This paper investigates the impact of social transfer programmes on school enrolment and child labour in Malawi utilizing a micro-simulation evaluation method. Four hypothetical cash transfer programmes, differentiated in terms of their conditions on children’s enrolment and gender, are considered. Results show that boys’ enrolment increases in all four scenarios, whereas girls’ enrolment incre...

A . This paper considers the problem of conducting inference on the regression coefficient in a bivariate regression model with a highly persistent regressor. Gaussian asymptotic power envelopes are obtained for a class of testing procedures satisfying a conditionality restriction. In addition, the paper proposes testing procedures that attain these power envelopes whether or not the innovation...

Here is a familiar history: modal logics (see [13]) were around for some time before a semantic framework was found for them (by Kripke and others).1 This framework did at least two Very Good Things for modal logics: 1) it connected the powerful mathematical tools of model theory to these logics, allowing a variety of technical results to be proven, and 2) it connected modal logics (more) firml...
