This paper deals with a special case of estimation with grouped data, where the dependent variable is only available for groups, whereas the endogenous regressor(s) is available at the individual level. By estimating the first stage using the available individual data, and then estimating the...

There is currently much debate about the effectiveness of foreign aid and about what kind of projects can engender economic development. There is skepticism about the ability of econometric analysis to resolve these issues, or of development agencies to learn from their own experience. In...

<p>The  robust version of the classical  instrumental variables, called Instrumental Weighted Variables (IWV) and the conditions for its consistency and $\sqrt{n}$-consistency  are recalled. The reasons  why the classical instrumental variables as well as  IWV were introduced and the idea of...</p>

I propose a method identification of structural vector autoregressions (SVARs) and simultaneous equations models (SEMs) with orthogonal structural shocks using testable identification restrictions. If some sparsity conditions are satisfied, the method produces a set of testable inclusions and...

In Canada, advocates of universal child care often point to policies implemented in Quebec as providing a model for early education and care policies in other provinces. While these policies have proven to be incredibly popular among citizens, initial evaluations of access to these programs...

There is empirical evidence of a cross-country positive association between the number of lawyers per capita and the extent of litigation. For instance, Spain has more litigation and more lawyers per capita than most OECD countries. How should this association be interpreted? In this paper we...

We examine the impact of bilateral and multilateral tax treaties on bilateral FDI stocks. First, we present panel regressions of the effects of treaties on FDI based on an extensive database of all OECD countries from 1985 onwards. We use geographic instruments to correct for the endogeneity of...
