We study a multi-sector model of growth with differences in TFP growth rates across sectors and derive sufficient conditions for the coexistence of a balanced aggregate growth path, with all aggregates growing at the same rate, and structural change, characterized by sectoral labor reallocation. The conditions needed are weak restrictions on the utility and production functions: goods should be...

This paper develops an endogenous growth model of a dual economy where human capital accumulation is the source of economic growth. The dualism between the rich individuals and the poor individuals exists in the mechanism of human capital accumulation. Rich individuals allocate labour time not only for their own production and knowledge accumulation but also to train the poor individuals. Stead...

In this paper we specialize the Ngai-Pissarides model of growth and structural change [American Economic Review 97 (2007), 429-443] to the case of three sectors, representing the primary (agriculture, mining), secondary (construction, manufacturing) and tertiary (services) sectors. On that basis we explore the dynamic properties of the model along the transition path to the steady-state equilib...

How does technological progress occur? Is the nature of innovation stable over time? We shed new light on these questions through a mixture of empirics and theory. We begin with an empirical analysis of patents granted by the United States Patent and Trademark Offi ce. This analysis reveals several striking facts that emphasize the increasing importance of novel combinations of technologies for...

This paper investigates the relationship between growth and inequality from a demographic point of view. In an extended model of the accidental bequest with endogenous fertility, we analyze the effects of a decrease in the old-age mortality rate on the equilibrium growth rate as well as on the income distribution. We show that the relationship between growth and inequality is at first positive ...

The paper examines the gains from North-South trade and their distribution. In a `new growth, new trade' framework, we examine the factors that determine four phases or stages of development in the South as equilibria: specialisation in a traditional good; the South in addition copies Northern innovative manufactured goods; the South begins to innovate in its own right and nally a stage in whic...

In this paper we extend the Lucas (1988) endogenous growth model to include sector-specific external effects and depreciation in both sectors. We derive analytically, the restrictions on the parameter space that are necessary and sufficient for the existence of balanced growth paths and equilibria. We demonstrate that in contrast to the original model, with the addition of an external effect an...

The paper analyzes how social barriers to communication affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labor, a negative relationship is shown to exist between social barriers to communication and total factor productivity (TFP), per capita consumption and reproducible cap...

This paper presents a microfounded theory of long-term development. We model the interplay between economic variables, namely the process of human capital formation and technological progress, and the biological constraint of finite lifetime expectancy. All these processes affect each other and are endogenously determined. The model is analytically solved and simulated for illustrative purposes...

This paper extends the two-class monetary growth model by incorporating fiscal activity along the lines of Pasinetti (Cambridge J. Econ. 13, 25–36). Despite this extension, the Cambridge equation is found to be one of long-run equilibria. It is shown that Fiscal policy decreases the accumulation of capital, through an increase in the proportional tax on profits. An inflationary monetary policy ...
