Why has China grown so fast? The role of physical and human capital formation

Cross-province growth regressions for China are estimated for the reform period. Two research questions are asked. Can the regressions help us to understand why China as a whole has grown so fast? What types of investment matter for China's growth? We address the problem of model uncertainty by adopting two approaches to model selection to consider a wide range of candidate predictors of growth. Starting from the baseline equation, the growth impact of physical and human capital is examined using panel data techniques. Both forms of capital promote economic growth. ‘Investment in innovation’ and private investment are found to be particularly important. Secondary school enrolment contributes to growth, and higher education enrolment even more so

Lifetime experiences of self-employment

This report, by the Policy Studies Institute, explores the patterns of labour market participation and pension provision among self-employed people. It is based on analyses of the 1994-95 Family and Working Lives Survey, a representative sample of more than 9,000 people in Great Britain aged 16 to 69 years. It draws on lifetime information on economic activity, family circumstances and pension provision

Libertarian Critiques of Consent in Sexual Offences

This paper uses a system of moral principles derived from Alan Gewirth's Principle of Generic Consistency to demonstrate both the moral necessity of adopting a libertarian approach to consent in sexual offences, and that such an approach is practically superior with regard to the policy objectives which English law seeks to pursue in this field. The paper achieves this through inquiring into the state of contemporary English law and then analysing its political and philosophical underpinnings on a diverse range of issues, from uncomplicated consent through to coercion, informed consent, and the age of consent. In each case alternatives are proposed which would remedy the moral and practical deficiencies in English law. However, the paper concludes that remedying the defects in English law is only an interim solution, and that no true answer to the contradictions which the law faces is possible without a wholesale rejection of the socio-economic oppression which the greater part of humanity face under capitalism. In light of this, the author takes the view that the sexual autonomy of all agents can only be preserved through a transition to a libertarian and socialist society

An Evaluation of Herbicides for Broadleaf-Weed Control in Rapeseed: Efficacy, Phytotoxicity, and Soil Persistence Studies

At the recommended rates (1.0 lb/A for trifluralin, ethalfluralin, EL5261; 0.75 lb/A for dinitramine; 1.2 lb/A for nitrofen), none of the herbicides we evaluated in these studies reduced rapeseed stands, yields, or test weights. However, at higher rates (1. 5, 3.0 lb A), dinitramine reduced rapeseed stands, but this did not result in decreased yields. None of the other herbicides reduced rapeseed stand, yield, or test weights when applied at up to four times the recommended rate. No trifluralin residues were detected in rapeseed whole-plant or seed samples. All of the herbicides provided adequate control of common lambsquarters (Chenopodium album L.). Corn spurry (Spergula arvensis L.) was controlled by trifluralin. ethalfluralin. EL-5261, and nitrofen. All of the herbicides except nitrofen controlled chickweed [Stellaria media (L.) Cyrillo]. In 1979, 51 per cent of the trifluralin applied remained at the end of the growing season in one study while 26 per cent remained in another study. The rate of degradation at three sites in 1979 were as follows (greatest to least); Delta Junction, Matanuska Valley, Fairbanks. Degradation rates of trifluralin were not significantly different in three soil types or at two different application rates. Trifluralin showed no signs of leaching through the soil profile. In 1981, 25 per cent of the trifluralin, 8 per cent of the ethalfluralin, and 24 per cent of the EL-5261 applied remained at the end of the growing season. Despite the relatively long persistence of these preplant, incorporated herbicides, yields and test weights of barley planted in succeeding years were not reduced. A benefit of these persistent residues was control of broadleaf weeds in the succeeding barley crop
