以政府职能转变推动收入分配改革

收入和财富分配的不平等一直是中国改革发展中的重要问题。针对中国经济的特点,可以从政府改革的角度来研究如何更好地进行收入分配改革。地方政府主导推动地方经济的做法对收入不平等的扩大起了重要作用,加快政府职能转换,是使收入分配改革真正落到实处的破局之处,也是实现收入分配合理化可行的第一步。要改变地方政府的经济职能,降低它直接参与基础设施的程度,改革地方土地财政,建立垂直管理机构,以分散它的一部分经济管理职能,为收入分配改革打开空间。     

阻断性压力源与工作-家庭冲突:谦卑和学习目标导向的调节作用

基于资源保存理论和压力交互模型,本研究探讨了阻断性压力源对工作-家庭冲突的影响及其边界条件.对国内120名企业员工的数据分析结果表明,阻断性压力源正向影响工作-家庭冲突,除此之外,谦卑和学习目标导向共同调节了阻断性压力源和工作-家庭冲突之间的关系,具体地,当谦卑和学习目标导向均高的时候,阻断性压力源与工作-家庭冲突之间的正向关系最弱;相反,对于谦卑和学习目标导向均低的个体来说,阻断性压力源对工作-家庭冲突的正向影响最强.     

State‐Society Synergy and Export Sophistication

This paper contributes to the recent research on “export sophistication,” or the composition of a country's export portfolio. The central question of the current study is what determines a country's level of export sophistication. I argue that a synergetic relationship between state and society positively contributes to the level of export sophistication. The logic behind the argument is that the socially optimal level of investment in new products can only be realized if both the firm and the government find it individually profitable to carry out the investment. In cases whereby either or both lacks private incentive to invest, higher synergy between public and private sectors makes such joint investments more likely to occur. This logic is formally illustrated using a simultaneous game with incomplete information. The central hypothesis is tested using time series cross‐sectional data. The key empirical novelty of this paper is the construction of a “synergy index” based on Peter Evans' conceptualization of the term. Overall, the data give good support to the hypothesis. This relationship is particularly robust for the subsample of countries with intermediate levels of synergy. Furthermore, there is evidence suggesting that state‐society synergy is subject to diminishing returns as its values get higher.

南水北调西线工程对四川省农牧业发展的影响研究

南水北调西线工程实施将使雅砻江、大渡河、金沙江下游水量大幅减少, 对四川省农牧业生产造成不利影响。由于修筑引水枢纽淹没农地, 因此, 每年对四川省第一产业增加值造成的经济损失为0.43亿元~0.86亿元; 同时, 减水也会降低四川甘孜、阿坝两州北部地区土地产出能力, 但不会直接导致第一产业增加值下降。为此, 本文提出了相应的对策建议。

Can negative interest rates really affect option pricing? Empirical evidence from an explicitly solvable stochastic volatility model

The profound financial crisis generated by the collapse of Lehman Brothers and the European sovereign debt crisis in 2011 have caused negative values of government bond yields both in the USA and in the EURO area. This paper investigates whether the use of models which allow for negative interest rates can improve option pricing and implied volatility forecasting. This is done with special attention to foreign exchange and index options. To this end, we carried out an empirical analysis on the prices of call and put options on the US S&P 500 index and Eurodollar futures using a generalization of the Heston model in the stochastic interest rate framework. Specifically, the dynamics of the option’s underlying asset is described by two factors: a stochastic variance and a stochastic interest rate. The volatility is not allowed to be negative, but the interest rate is. Explicit formulas for the transition probability density function and moments are derived. These formulas are used to estimate the model parameters efficiently. Three empirical analyses are illustrated. The first two show that the use of models which allow for negative interest rates can efficiently reproduce implied volatility and forecast option prices (i.e. S&P index and foreign exchange options). The last studies how the US three-month government bond yield affects the US S&P 500 index.     

Shanxi Merchants’ Multilevel Financial System in Ming and Qing Dynasties,China

In the Ming and Qing Dynasties (1368–1911), China saw rapid development in industrial and commercial sectors. Over this period, a group of merchants originating from the inland province of Shanxi gradually built a multilevel financial system and became leaders in China’s banking sector. The system of financial institutions they established (pawnshops, seal shops, money shops, loan banks, and draft banks) each had a unique business model, with specific target client group and carefully designed risk management. They were also interconnected to allow for flexible capital flows, contributing to the fast economic growth in this period. Nevertheless, the traditional system also had limitations, leading to its replacement by modern banks eventually.     

Archaeological heritage tourism in China: the case of the Daming Palace from the tourists' perspective

Archaeological heritage tourism has been critical in historic cultural revival, archaeological knowledge dissemination, environment upgrading, and local community improvement. Little has been undertaken to evaluate the effectiveness and consequences of archaeological heritage projects in China from the tourist perspective. This study of the Daming Palace Heritage Site in Xi’an illustrates how archaeological and cultural resources have contributed to tourists' experiences. Through investigating an array of approaches that have been applied to advance tourists' understanding of archaeological and cultural resources, the paper proposes that more versatile methods and creative works are to be integrated to develop effective interpretative methods for both education and entertainment purposes. Local government needs to change its top-down approach to a more inclusive one, to establish strong networks among state and non-state stakeholders, and to promote their collective involvement in archaeological heritage tourism. Heritage site packaging strategies and partnerships among heritage resources citywide are advocated. More attention should be given to how to integrate various resources of local communities into heritage tourism. The current organization of government-run archaeological heritage in China calls for more opportunities for archaeologists to contribute actively with their expertise to enhance interpretive programmes and general tourist experience.
