abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

We model ‘new ideas’ production in a panel of 17 emerging countries. Our results reveal: (i) ideas production is duplicative, (ii) externality associated with domestic knowledge stocks is of above unit factor proportionality, (iii) OECD countries raise the innovation-bar for emerging countries, (iv) there is no significant knowledge diffusion across emerging countries, and (v) growth in emergin...

The development of the financial system is shown, both historically and in contemporary data, to be adversely affected by inequality in the distribution of land. To accommodate these empirical findings, a theory is developed that highlights the incentives of landowners to oppose competition in the financial sector. The theory provides an explanation for the co-incident development of the financ...

This paper presents evidence on the contribution of public capital (infrastructure) to aggregate economic performance using panel data for the U.S. states from 1970 to 2005. Attempts to quantify the role of public or government capital in the production of aggregate output have been beset by thorny econometric issues since the early 1990s. We present estimates of the output elasticity of public...

The Inequality-Growth Plateau We examine the (potentially nonlinear) relationship between inequality and growth using a method which does not require an a priori assumption on the underlying functional form. This approach reveals a plateau completely missed by commonly used (nonlinear) parametric approaches the economy first expands rapidly with a large decline in inequality, plateaus when ineq...

We use latent class analysis to categorize development experiences. This technique allows us to consider a broad range of country characteristics including per capita income growth, health, inequality, environmental performance, and life satisfaction. We show that each of these indicators is important in explaining the classifications based on the quality of growth. We then predict membership i...
