In this paper we study the welfare effect of a monopoly innovation. Unlike many partial equilibrium models carried out in previous studies, general equilibrium models with non-price-taking behavior are constructed and analyzed in greater detail. We discover that technical innovation carried out...

The protection of intellectual property rights (IPR) and the distribution of rent are central issues in R&D-based growth models with the return to innovation serving as the engine of growth. In this paper the authors consider the strength of the intellectual property rights and franchise...

The most popular general univariate polarization indices for discrete (Esteban and Ray 1994), and continuous (Duclos, Esteban and Ray 2004) variables are combined and extended to describe the extent of polarization between agents in a distribution defined over a collection of many discrete and...

Despite the formal rigour that attends social and economic measurement, the substantive meaning of particular measures could be compromised in the absence of a clear and coherent conceptualization of the phenomenon being measured. A case in point is afforded by the status of a focus axiom in the...

Much analysis in macroeconomics empirically addresses economy-wide incentives behind consumer/investment choices by using insights from the way a single representative household would behave. Heterogeneity at the micro level can jeopardize attempts to back up the representative consumer...

The Special Report on Emissions Scenarios (SRES) has been widely used to analyze climate change impacts, vulnerability and adaptation. The storylines behind these scenarios outline alternative development pathways, which have been the base for climate research and other studies at global,...

This paper proposes a multidimensional procedure for jointly assessing the absolute and relative pro-poorness of growth. It is also a procedure for testing whether poverty comparisons can be made over classes of indices that incorporate both absolute and relative views of poverty. Besides being...

This paper examines three possible approaches to pro-poor growth. The first one assumes that the poverty line remains constant in real terms over time. The second perspective examines the case where the poverty line is equal to half the median of the income distribution but assumes that such a...

Two conversion schemes are usually employed for assessing personal-income inequality from household equivalent incomes: to weight household units by size or by needs. Using data from the Luxembourg Income Study, the authors show the sensitivity of country inequality rankings to conversion...

Aphorisms that "Rising tides raise all boats" or that material advances of the rich eventually "Trickle Down" to the poor are really maxims regarding the nature of stochastic processes that underlay the income/wellbeing paths of groups of individuals. This paper looks at the implications for the...
