This paper examines the impact of the birth rate on economic growth by using a panel data set of 28 provinces in China over twenty years. Because China’s one-child policy applied only to the Han Chinese but not to minorities, this unique affirmative policy allows us to use the proportion of minorities in a province as an instrumental variable to identify the causal effect of the birth rate on e...

The Malthus Microbiological Growth Analyser has proved to be sensitive in detecting conductivity changes due to anaerobic metabolism in a number of widely used blood culture media. Freshly prepared cooked meat media and Thiol medium yielded the greatest gross conductivity changes, and were more sensitive of anaerobic metabolism than other media. Failure of the instrument to detect anaerobic met...

Making strict use of Malthus’ (1798) so-called preventive check hypothesis – that fertility rates vary inversely with the price of food – the current study offers a new a...
