This decision often paves way to several aspects an individual professional career and intellectual development. However, choice made unawares involuntarily, also because it taken by individuals initial stages their profession with still limited information. The fact that dictated available opportunities (e....

Harry J. Holzer and Sandy Baum’s recent book, Making College Work: Pathways to Success for Disadvantaged Students, provides an excellent up-to-date review of higher education. My first summarizes its key themes: (i) who gains from college why, (ii) mismatch the need more structure, (iii) problems with remediation, (iv) financial barriers, (v) promise comprehensive support. I then critique book’...

Empirical researchers often combine multiple instrumental variables (IVs) for a single treatment using two-stage least squares (2SLS). When effects are heterogeneous, common justification including IVs is that the 2SLS estimand can be given causal interpretation as positively weighted average of local (LATEs). This requires well-known monotonicity condition. However, we show with more than one ...

The predictions of the crystal structure of 3-azabicyclo[3.3.1]nonane-2,4-dione submitted in the 2001 international blind test of crystal structure prediction (CSP2001) led to the conclusion that crystal structures containing an alternative hydrogen bonded dimer motif were energetically competitive with the known catemer-based structure. Here we report an extensive search for a dimer-based crys...
