Over the past half-century we have witnessed a gradual trend towards increased globalization. This phenomenon includes such diverse processes as the greater mobility of capital, goods, and services, as well as increasing diffusion of ideas, technology, and norms. Given the ubiquitous and multi-faceted nature of globalization, we evaluate the effect of economic, social, and political global integration on a particularly important outcome - human well-being. Theoretically, we argue that globalization has a large number of different effects on human well-being, including multiple positive effects and multiple negative effects. Empirically, we analyze the impact of globalization on well-being using a pooled data set, including 132 countries over the time period 1970- 2007. We find that, on balance, all three forms of globalization positively affect well-being.
