China's regional income disparityAn alternative way to think of the sources and causes1

Using data on China's provincial economies for the period 1978–2005, we decomposed the causes and factors that have contributed to inter‐regional per capita income disparity. Variance in capital per employee and variance in capital elasticity are found to be the two main sources of income disparity while the employment–labour force ratio is shown to be an important factor in containing the rise of income disparity. An analysis on inter‐regional factor reallocation effects reveals their relatively small and insignificant contributions to overall growth performance. It is also discovered that capital has in most years flowed in the right direction to pursue higher marginal productivity across provincial economies. Inter‐provincial labour movement, on the other hand, had not displayed significant equilibrating effects until institutional reforms started to allow freer inter‐regional labour mobility in later years. Generally, we conclude that market‐oriented factor mobility has played a crucial role in equalizing factor returns as well as enhancing growth efficiency across regions.     

中国苹果出口的竞争力分析

我国是世界苹果生产大国,苹果种植面值、产量均居世界第一.同时,苹果也是我国传统的出口农产品.但近年来,我国苹果出口总量占我国苹果生产总量的比例却十分少.通过贸易竞争力指数和显性比较优势指数从整体上评估我国苹果的国际竞争力,分析我国苹果出口具有规模、价格、资源、区位四大优势,从内外因两方面分析我国苹果出口存在的问题,指出我国苹果产业本身就存在产品质量偏低、商品化处理不足、贮藏保鲜技术滞后,出口目的市场过于集中,提出相应优化措施.     

一种新型环境友好污水处理工艺——蚯蚓生态滤池

Dynamic scoring: Alternative financing schemes

Neoclassical growth models predict that reductions in capital or labor income tax rates are expansionary when lump-sum transfers are used to balance the government budget. This paper explores the consequences of bond-financed tax reductions that bring forth a range of possible offsetting policies, including future government consumption, capital tax rates, or labor tax rates. Through the resulting intertemporal distortions, current tax cuts can be expansionary or contractionary. The paper also finds that more aggressive responses of offsetting policies to debt engender less debt accumulation and less costly tax cuts.

Asymmetric volatility in the foreign exchange markets

We examine the presence or absence of asymmetric volatility in the exchange rates of Australian dollar (AUD), Euro (EUR), British pound (GBP) and Japanese yen (JPY), all against US dollar. Our investigation is based on a variant of the heterogeneous autoregressive realized volatility model, using daily realized variance and return series from 1996 to 2004. We find that a depreciation against USD leads to significantly greater volatility than an appreciation for AUD and GBP, whereas the opposite is true for JPY. Relative to volatility on days following a positive one-standard-deviation return, volatility on days following a negative one-standard-deviation return is higher by 6.6% for AUD, 6.1% for GBP, and 21.2% for JPY. The realized volatility of EUR appears to be symmetric. These results are robust to the removal of jump component from realized volatility and the sub-samplings defined by structural-changes. The asymmetry in AUD, GBP and JPY appears to be embedded in the continuous component of realized volatility rather than the jump component.
