This paper presents a fully specified model of long-run growth in which knowledge is assumed to be an input in production that has increasing marginal productivity. It is essentially a competitive equilibrium model with endogenous technological change. In contrast to models based on diminishing returns, growth rates can be increasing over time, the effects of small disturbances can be amplified by the actions of private agents, and large countries may always grow faster than small countries… 
This paper studies the short-run and long-run behavior of a competitive economy in which both the discount factor and technological change are endogenously determined. In particular, the effect of

On capital increasing returns and long run growth in a model of overlapping generation
This contribution illustrates the role of an imperfectly competitive process of capital accumulation in the growth process. It emphasizes the central role of investment in long run outcomes. Whereas

The wide cross-country disparity in rates of economic growth is the most puzzling feature of the development process. This paper describes a class of models in which this heterogeneity in growth
Sustained endogenous growth with decreasing returns and heterogeneous capital
The possibilityof sustained long-run growth is typically associated with the presence of some endogenous "engine of growth". It may allow the economy to grow without bound despite the use of some
On Endogenizing Long-Run Growth
This assessment of recent theoretical work on endogenous growth identifies three different engines of long-run growth: (1) the asymptotic average product of capital is positive; (2) labor
Comparative Advantage and Long-Run Growth
We construct a dynamic, two-country model of trade and growth in which endogenous technological progress results from the profit-maximizing behavior of entrepreneurs. We study the role that the
Monetary Unions and Long-Run Growth
This paper develops two complementary models of monetary unions and long-run growth. The key result is that a reduction in foreign exchange costs via monetary unification provides a positive growth
Market restrictions and economic growth
This paper introduces endogenous growth into a standard two-sector model to study the growth effect of changes in organization of markets. We find that when the rents from land expand to keep pace
A Dynamic Model of Investment and Endogenous Growth
Models of endogenous growth assume that private investment in either physical or human capital yields positive externalities to production possibilities as a whole. But what is the structure of such


A Complete Characterization of Optimal Growth Paths in an Aggregated Model with a Non-Concave Production Function
The convexity of technology has played a crucial role in economic analyses of optimal one-sector growth problems. For example, two of the key results on the traditional model of Ramsey (1928) that
Optimal growth with scale economies in the creation of overhead capital
Following closely the approach to optimal economic growth taken in the work of Frank Ramsey [11], a highly simplified two-sector model is presented in which the " overhead capital " sector exhibits
Productivity Growth, Convergence, and Welfare: What the Long-run Data Show
Maddison's 1870-1979 data are analyzed, showing the historically unprecedented growth in productivity, GDP per capita and exports and the remarkable convergence of productivities of industrialized
Optimal growth under factor augmenting progress
Abstract Optimal growth is considered in the usual neoclassical one-good model of economic growth with factor augmenting technical progress. If a program is optimal (in the sense of maximizing a
Dynamic Optimization with a Non-Convex Technology: The Case of a Linear Objective Function
The paper studies the problem of optimal intertemporal allocation in an aggregative model with a non-convex technology set and a discounted sum of consumptions as the objective function. The study
Increasing returns, imperfect markets, and trade theory
Publisher Summary This chapter discusses two major issues: explanations of trade patterns and gains from trade. The classical traditions were mainly concerned with gains from trade and other welfare

Optimal Growth with a Convex-Concave Production Function
NUMEROUS STUDIES OF OPTIMAL MODELS in economic growth theory conducted with the aid of Pontryagin's maximum principle [3] led to important qualitive conclusions about the optimal development of
The Economic Implications of Learning by Doing
It is by now incontrovertible that increases in per capita income cannot be explained simply by increases in the capital-labor ratio. Though doubtless no economist would ever have denied the role of
Optimum saving with economies of scale
There are many problems in economics where it is important to think of investment taking place in discrete lumps rather than as a continuous flow. These are usually problems where fixed costs are
