This paper examines the effects of three alternative rules for public investment on output growth in a model with private and public capital. The rules considered are: (i) a fixed ratio of public capital to output; (ii) a fixed growth rate for public capital; and (iii) a fixed ratio of public...

The Paper examines the interactions between economic integration and population agglomeration in a middle product economy displaying neoclassical growth. There are two vertically-integrated economies. Each consists of a large number of final good competitive firms operating plants in both...

Pooled regressions, first of eight and then of sixteen countries, show a steady and robust process of endogenous growth in Europe since 1870, interrupted only by the events of World War II and the impact of convergence towards US levels of performance in the 1950s and the 1960s. This result...

If capital is an essential input, the neoclassical growth model has a steady state with zero capital. From this, one is inclined to conclude that an economy starting without capital can never grow. We challenge this view and claim that, if the production function satisfies the Inada conditions,...

How did Europe overtake China? We construct a simple Malthusian model with two sectors, and use it to explain how European per capita incomes and urbanization rates surged ahead of Chinese ones. Productivity growth can only explain a small fraction of rising living standards. Population dynamics...

This paper seeks to explain the significant variations in the social contract observed across nations. It shows how countries with similar technologies and preferences, as well as equally democratic political systems, can sustain very different average and marginal tax rates. Similarly, it...

The paper examines the welfare gains from North-South trade and their distribution. We construct an endogenous growth North-South model with four Southern stages of development as possible equilibria: specialisation in a traditional good; the South in addition copies Northern high-tech...

Despite being the standard growth model for several decades, little is actually known analytically about the dynamic properties of the neoclassical Ramsey-Cass-Koopmans growth model. This paper derives analytically the properties of the endogenous saving rate when technology takes the Constant...

The concepts of s-convergence, absolute b-convergence and conditional b-convergence are discussed in this paper. The concepts are applied to a variety of data sets that include a large cross section of 110 countries, the sub-sample of OECD countries, the states within the United States, the...

We consider infinite-horizon variational problems on different spaces of curves in presence of constraints on the state. We establish several necessary conditions of optimality, and give relations between these different problems.
