Abstract:

This report surveys six influential econometric textbooks in terms of their mathematical treatment of causal concepts. It highlights conceptual and notational differences among the authors and points to areas where they deviate significantly from modern standards of causal analysis.  We find that econonometric textbooks vary from complete denial to partial acceptance of the causal content of econometric equations and, uniformly, fail to provide coherent mathematical notation that istinguishes causal from statistical concepts. This survey also provides a panoramic view of the state of causal thinking in econometric education which, to the best of our knowledge, has not been surveyed before … // Continuer la lecture de « Regression and causation: a critical examination of six econometrics textbooks »

… The group we created, ‘Marak Levinsky’ (Levinsky Soup), embedded itself more deeply into Israeli society and the mass media than the ‘Group of 400’, which has since been almost forgotten. The Marak Levinsky venture has become an emblem for social initiatives which empower citizens to stand up and do something. For more than 500 days we have managed daily shifts in the park to distribute food and clothing for hundreds of refugees who were unemployed and arrived from prison (where they were held after crossing the border into Israel) with few clothes and sometimes barefoot or only with flip-flops.  Continuer la lecture de « The formal political process isn’t always the best way to effect social change »

A tiny wealthy male elite is behind most of the biggest contributions to the 2012 election cycle in the US, a new study shows. The report comes just as the US Supreme Court considers whether it should strip a ceiling on political donations. In a case the Supreme Court will begin hearing next Thursday, Shaun McCutcheon, a wealthy donor backed by the Republican National Committee, is challenging this aggregate limit on how much an individual may donate overall to candidates, parties and political action committees (PACs) over an election cycle.  Continuer la lecture de « US: Tiny white elite dominates US political donor landscape – study »
