We identify anthropogenic contributions to atmospheric CO2 measured at Mauna Loa using a statistical automatic model selection algorithm (Autometrics).  We find that vegetation, temperature and other natural factors alone cannot explain the trend or the variation in CO2 growth.  Industrial...

This paper shows that the behaviour of inventories is not symmetrical and that their modelling requires more than just a linear regression. Models of inventory behaviour are described and symmetric and non-symmetric-error-correction models are formulated which divide the changes in production...

Here we assume that the logarithmic asset price is given by a semimartingale. Jacod (2006) has derived an infeasible central limit theorem for the realised variance in such a general framework. However, here we focus on constructing a feasible limit theorem. We propose a new estimator for the...

How much does public capital matter for economic growth? How large should it be? This paper attempts to answer these questions, taking the case of SSA countries. It develops and estimates a model that posits a nonlinear relationship between public investment and growth, to determine the...

The paper uses the Lewis model as a framework for examining the labour market progress of two labour-abundant countries, China and South Africa, towards labour shortage and generally rising labour real incomes. In the acuteness of their rural-urban divides, forms of migrant labour, rapid...

This paper is a preliminary draft of a chapter for the new Handbook of Labour Economics edited by Orley Ashenfelter and David Card and Published by North Holland.

This paper explores whether the patent law and intellectual property rights (IPR) system have resulted in innovation in China during the reform period. It appears that the patent laws have produced a stock of patents, where the success rates of patent applications are fairly uniform across the...

This paper analyzes regime shifts in the stochastic process of economic growth of six major OECD countries over three decades. For the statistical measurement of the underlying global business cycle, we generalize Hamilton's model of the US business cycle to a Markov-switching vector...

This paper examines the relation between financial, corporate and legal systems, and economic performance in different countries. It reviews international comparisons that undertake detailed analyses of individual, developed countries and studies that use large, cross-country data banks,...

The paper extends existing work on inequality and economic development by estimating a cross-country structural model that identifies bi-directional relationships between income inequality and other indicators of social and economic development. Overall, lower inequality is associated with...
