我国资本市场监管效率实证分析

中国资本市场已经运行了很多年，随着中国加入WTO后市场的全面开放，对中国资本市场监管成效的研究可以有效地认识资本市场管理的不足。而对中国资本市场效率的研究都集中在20世纪90年代前期，因此有必要对现行的资本市场监管成效进行实证研究。     

武汉市农贸市场超市化改造问题研究

武汉作为全国"农改超"先行的特大城市之一,经过两年多的实践与探索,"农改超"已初见成效,但仍存在市场主体利益关系复杂、超市生鲜食品营运成本较高、超市农业发展滞后、农产品物流配送体系不健全、制度环境不够宽松等制约因素.为此,需要调整利益关系格局、培育壮大生鲜经营主体、大力发展超市农业、构建现代农产品物流配送体系和营造"农改超"的良好环境.     

城市供水定价对居民资源节约行为影响的博弈分析

水资源紧缺与构建和谐社会,引致水资源定价改革不断深入。水资源经济稀缺性与公共物品属性标志水资源定价的特殊性。在分析中国城市供水价格现状基础上,建立政府、供水企业和两类之间的城市供水定价的层次博弈模型,可以研究统一水价和阶梯水价策略对居民水消费行为选择的影响。

Quantile spillovers and dependence between Bitcoin,equities and strategic commodities

This paper has two aims. We first examine the dynamic spillovers between Bitcoin and 12 developed equities, gold, and crude oil for different market conditions using a Bayesian Time-Varying Parameter Vector Autoregressive (TVP-VAR) model with daily spot prices. Our econometric approach enables us to capture the left and right tails as well as the shoulders of the return distribution corresponding to volatility spillovers under the bear, normal, and bull market states among these financial assets. We quantify and trace the dependence and directional predictability from Bitcoin to other assets using the sample cross-quantilogram. Our key findings offer convincing evidence of time variation in the level of volatility. Spillovers between Bitcoin and other financial assets intensify during extreme global market conditions. Secondly, results from the cross-quantilogram indicate strong dependence and positive directional predictability between Bitcoin and most equities and crude oil when market returns are bullish. However, during the bearish market period, there is negative dependence and predictability from Bitcoin to stocks in Finland, the Netherlands, the U.S.A, and the crude oil market only. This implies that Bitcoin can act as a hedge to stocks in Finland, the Netherlands, the U.S.A, and the crude oil market. However, insignificant dependence and directional predictability from Bitcoin to the remaining assets indicate that Bitcoin may act as a safe-haven to these assets during bearish markets. Our findings hold important implications for both international investors and portfolio managers who consider Bitcoin as part of their portfolio diversification and other investment strategies.

Political booms and currency crises

This paper shows evidence that political booms, defined as the rise in governments’ popularity, are associated with a higher likelihood of currency crises. The reasoning behind this finding is that prudent economic policies to address underlying weaknesses in the economy may be political costly for incumbent governments in the short-term. Hence, popularity-concerned governments may not have enough incentives to take such corrective actions in a timely manner. This approach, in turn, can deteriorate economic fundamentals and increase related risks in the economy which can eventually lead to crises. This paper sheds light on this phenomenon in the case of currency crises, suggesting that currency crises can be viewed as “political booms gone bust” events. Moreover, it finds that higher international reserves, higher exports, and a higher degree of financial openness alleviate the effect of political booms on currency crises.     

企业退出出口市场行为与企业的经营表现——基于倾向评分匹配的经验分析

文章运用倾向评分匹配方法分析了企业退出出口市场行为对其经营表现的影响。研究结果表明,经营表现越差的出口企业退出出口市场的概率越大;企业退出出口市场行为对企业经营表现的影响主要体现在影响就业增长和产出增长方面,而对劳动生产率的影响总体不显著。具体表现为,企业退出出口市场会对其就业增长和产出增长产生持续的显著负向作用,这说明我国国内需求尚不足以使企业退出出口市场后继续保持退出前的就业增长率和产出增长率。因此,在提倡出口转内销的同时需注重提高出口企业在国际市场竞争中的存活率。
