Why is the Chinese Saving Rate so High?
    Read Paper
Guonan Ma & Wang Yi, World Economics, March 2011
China’s saving rate is high from many perspectives – historical experience, international standards and model predictions. Furthermore, the average saving rate has been rising over time, with much of the increase taking place in the 2000s. What sets China apart from the rest of the world is that its rising aggregate saving has reflected high savings rates in all three sectors: corporate, household and government. Our evidence casts doubt on the proposition that distortions and subsidies account for China’s high saving rate. Instead, we argue that tough corporate restructuring (including pension and home ownership reforms), a marked Lewismodel transformation process (where the average wage exceeds the marginal product of labour in the subsistence sector) and rapid ageing process have all played more important roles. Such structural factors suggest that the Chinese saving rate may peak over the coming years.
Measuring Global Drug Markets
    Read Paper
Peter Reuter & Victoria Greenfield , World Economics, December 2001
The continuing demand for measures of the size of global drug revenues has produced a supply of numbers that consistently overstate international financial flows. This paper shows that, rather than $500 billion, the annual figure in trade terms may be about $25 billion. As with many refined agricultural products, most of the revenues go to distributors rather than to primary producing countries. The authors explore the need for estimates of the global drug markets, address the difficulties of obtaining ‘good’ numbers, and describe opportunities for developing better estimates of flows and revenues. There are at least three reasons for caring about the numbers: they can help to improve understanding of the drug production and consumption problem and identify appropriate policy responses.
