Many political economic theories use and emphasize the process of voting in their explanation of the growth of Social Security, government spending, and other public policies. But is there an empirical connection between democracy and Social Security program size or design? Using some new...

We construct a model that combines elements of endogenous growth with the convergence implications of the neoclassical growth model. In the long run, the world growth rate is driven by discoveries in the technologically leading economies. Followers converge toward the leaders because copying is...

We think of the expected real interest rate for ten OECD countries (our counterpart of the world economy) as determined by the equation of aggregate investment demand to aggregate desired saving. Stock-market returns isolate shifts to investment demand, and changes in oil prices, monetary...

A key economic issue is whether poor countries or regions tend to grow faster than rich ones: are there automatic forces that lead to convergence over time in levels of per capita income and product? After considering predictions of closed- and open-economy neoclassical growth theories, we...

Estimates of democracy's effect on the public sector are obtained from comparisons of 142 countries over the years 1960-90. Based on three tenets of voting theory -- that voting mutes policy preference intensity, political power is equally distributed in democracies, and the form of voting...

This paper examines the robustness of explanatory variables in cross-country economic growth regressions. It employs a novel approach, Bayesian Averaging of Classical Estimates (BACE), which constructs estimates as a weighted average of OLS estimates for every possible combination of included...

In this paper we argue that the relevant decision for the majority of US households is not the fraction of assets to be held in interest bearing form, but whether to hold any of such assets at all (we call this `the decision to adopt' the financial technology). We show that the key variable...

This is a survey of the literature on Economic Growth. In the introduction we analyze the main differences between exogenous and endogenous growth models using fixed savings rate analysis. We argue that in order to have endogenous growth there must be constant returns to the factors that can be...

166 countries have some kind of public old age pension. What economic forces create and sustain old age Social Security as a public program? We document some of the internationally and historically common features of Social Security programs including explicit and implicit taxes on labor supply,...

We propose a positive theory that is consistent with two important features of social security programs around the world: (1) they redistribute income from young to old and (2) they induce retirement. We construct a voting model that includes a political campaign' or debate' prior to the...
