“…; and Alesina and Wacziarg 1999+ 68+ For example, Stone Sweet and Caporaso 1998 show that over time, a linear relationship exists between the amount of transnational economic transactions and the pressure exerted by private suitors who demand supranational rules; see also Stone Sweet and Brunell 1998;andCarrubba andMurrah 2005+ 69+ See Pollack 1997;Alter 2001, chaps+ 2 and 5; and Maduro 1998, chap+ 3 on "majoritarian activism+" pean area of nondiscrimination+ We distinguish two subdimensions of this form of integration: protection against discrimination based on characteristics such as gender, age, and ethnicity, on the one hand; and discrimination-free transnational access to the social security systems of the member states, on the other+ In many member states, the improvement in protection against discrimination based on gender, age, sexual orientation, ethnic origin, or religious affiliation is attributable to the EU+ This is particularly true for protection against on-the-job discrimination and against discrimination blocking access to labor markets+ While such policies are not redistributive in a stronger sense, they have social content because they protect market participants who would be likely to perform worse if discrimination were legal+ Both European politics and judicial case law are responsible for these successes+ For example, the commission's negotiation skills are to credit for four antidiscrimination directives that were passed in the years 2000 to 2004+ 70 Even if the relative importance of political agreements in creating European antidiscrimination policy is greater than in the measures we discussed in marketenforcing policy, we should not underestimate the major role case law has played in formulating European equal treatment policy+ On the basis of comparatively few clauses in the European treaties-in particular, the principle of wage equality for the sexes and the free movement of workers-the ECJ has developed a farreaching antidiscrimination jurisprudence that has had an impact in all member states~and that is among the reasons why some, such as Alesina and Wacziarag, argue that European integration has gone too far!+ 71 Examples of the most recent case law are the Mangold decision, in which the ECJ overruled an element of the German labor market reforms that aimed at making fixed-term contracts more flexible for older employees; the Maruko decision, which came down against the refusal to award survivor pensions to homosexual partners; and the Coleman decision, in which the ECJ expanded previous case law governing the workplace to also cover family members of employees+ 72 Many other examples for the extensive equal treatment case law of the ECJ could be mentioned+ We suggest treating this line of case law as being "social" in the wider sense, but not as an element of~or a substitute for! " Polanyian," market-restricting policies at the European level: it aims to create free access to the market, unhampered by discrimination, in other words: free but fair markets+…”
