Early Land Redistribution and the Food Security of South African Households: Micro-econometric evidence from national data

The South African land redistribution program, which was launched in 1994, has been widely criticised for its slow pace as well as its seemingly limited contribution to poverty reduction, but to the best of my knowledge, no econometric evidence of the impact of land redistribution has been provided so far, as it is the case in most countries having experienced this type of policies. This paper presents estimates of the impact of having received a land grant on households´ self-reported difficulties in meeting food needs in the past 12 months, using data from the September 2002 South Africa National Labour Force Survey. Bivariate probit estimates controlling for potential self-selection of land reform beneficiaries indicate that participation in the land grant scheme has increased food insecurity for poorer participants, whilst decreasing it for comparatively better-off participants

Growth and Pollution Convergence: Theory and Evidence

Stabilizing pollution levels in the long run is a pre-requisite for sustainable growth. We develop a neoclassical growth model with endogenous emission reduction predicting that, along optimal sustainable paths, pollution growth rates are (i) positively related to output growth (scale effect) and (ii) negatively related to emission levels (defensive effect). This dynamic law reduces to a convergence equation that is empirically tested for two major and regulated air pollutants - sulfur oxides and nitrogen oxides - with a panel of 25 European countries spanning the years 1980-2005. Traditional parametric models are rejected by the data. More flexible regression techniques confirm the existence of both the scale and the defensive effect, supporting the model predictions.Air pollution, convergence, economic growth, nonparametric regressions

The Puzzle of Muslim Advantage in Child Survival in India

The socio-economic status of Indian Muslims is, on average, considerably lower than that of upper caste Hindus. Muslims have higher fertility and shorter birth spacing and are a minority group that, it has been argued, have poorer access to public goods. They nevertheless exhibit substantially higher child survival rates, and have done for decades. This paper documents and analyses this seeming puzzle. The religion gap in survival is much larger than the gender gap but, in contrast to the gender gap, it has not received much political or academic attention. A decomposition of the survival differential reveals that some compositional effects favour Muslims but that, overall, differences in characteristics between the communities and especially the Muslim deficit in parental education predict a Hindu advantage. Alternative outcomes and specifications support our finding of a Muslim fixed effect that favours survival. The results of this study contribute to a recent literature that debates the importance of socioeconomic status (SES) in determining health and survival. They augment a growing literature on the role of religion or culture as encapsulating important unobservable behaviours or endowments that influence health, indeed, enough to reverse the SES gradient that is commonly observed.religion;caste;gender;child survival;anthropometrics;Hindu;Muslim;India

Universal dissipation scaling for non-equilibrium turbulence

It is experimentally shown that the non-classical high Reynolds number energy dissipation behaviour, $C_{\epsilon} \equiv \epsilon L/u^3 = f(Re_M)/Re_L$, observed during the decay of fractal square grid-generated turbulence is also manifested in decaying turbulence originating from various regular grids. For sufficiently high values of the global Reynolds numbers $Re_M$, $f(Re_M)\sim Re_M$.Comment: 5 pages, 6 figure
