Technological Change and the Education Premium in Canada: Sectoral Evidence

It has been well documented that the education premium measured by the wage difference between university and high school graduates has remained constant over the past two decades in Canada. Despite this stable pattern at the aggregate level, skill-biased technology could have important implications for the inter-industry wage structure. In a multi-sector economy where technological innovations are skewed towards certain industries, imperfect labour mobility implies a positive relationship between the education premium and the technological change in industry. Using data from the Survey of Consumer Finance and the Labour Force Survey, the authors obtain empirical results that would appear to confirm this link: university graduates in research and development- intensive industries are better paid . Yet, this positive correlation is largely due to the fact that high-tech industries attract more professionals who are more educated than the average university graduate.Labour markets

Strong and Confined Acids Enable a Catalytic Asymmetric Nazarov Cyclization of Simple Divinyl Ketones

We report a catalytic asymmetric Nazarov cyclization of simple, acylic, alkyl-substituted divinyl ketones using our recently disclosed strong and confined imidodiphosphorimidate Brønsted acids. The corresponding monocyclic cyclopentenones are formed in good yields and excellent regio-, diastereo-, and enantioselectivities. Further, the chemical utility of the obtained enantiopure cyclopentenones is demonstrated

Sulfoxide-mediated Umpolung of alkali halide salts

A new protocol for the direct two-electron oxidative Umpolung of alkali halide salts is reported. This procedure, relying on the use of a commercially available sulfoxide as the oxidant, allows the electrophilic halogenation of carbonyl compounds as well as halolactonisation reactions to proceed from the corresponding sodium salts, at room temperature and under mild conditions
