This paper sheds new light on subset hypothesis testing in linear structural models in which instrumental variables (IVs) can be arbitrarily weak. For the first time, we investigate the validity of the bootstrap for Anderson-Rubin (AR) type tests of hypotheses specified on a subset of structural...

We investigate the asymptotic validity of the bootstrap for Durbin-Wu-Hausman (DWH) tests of exogeneity in linear IV regressions, with or without identification. Our analysis of the properties (size and power) of the proposed bootstrap tests provides some new insights and extensions of earlier...

Regular use of effective health-products such as insecticide-treated mosquito nets (ITN) by a household benefits its neighbors by (a) reducing chances of infection and (b) raising awareness about product-effectiveness, thereby increasing product-use. Due to their potential social benefits and...
