We present theory and evidence to suggest that, in the context of analyzing global poverty, the EKS approach to estimating purchasing power parities yields more appropriate international comparison of real incomes than the Geary-Khamis approach. Our analysis of the 1996 and 2005 International...

The apparent convergence of OECD income levels since 1950 is subjected to rigorous testing that suggests that there has occurred a systematic process of catching up in levels of total factor productivity. An econometric model of relative economic growth exhibits parameter stability over three...

Widely used 'purchasing power parity' comparisons of per capital GDP are not true quantity indexes and are subject to systematic substitution bias. This bias may distort measurement of convergence and divergence. Extending Hal R. Varian's nonparametric construction of a true index gives the set...

The response of union utility to labor-saving innovation is analyzed within a framework of oligopolistic competition in the product market, taking account of wage bargaining under several alternative structures of industrial relations. Conditions are established under which wages and employment...

Two recently improved sets of cross-country panel data are combined in order to re-examine the effects of population growth and fertility on economic growth. Using a 107 country panel data set covering 1960-85, we find that high birth rates appear to reduce economic growth through investment...

Under what circumstances will firms agree on the choice of roles of leader and follower in the von Stackelberg duopoly model? A key determinant is the slope of the firms' reaction function (in either price or quantity space). The duopolists will disagree over the choice of roles if they have...

Recent modelling of endogenous growth allows for both endogenous creation of ideas for new technology through R&D and endogenous accumulation of human capital. This paper extends the literature by addressing two counterfactual predictions and reconsidering the need for a policy trade-off where...
