Option pricing in the moderate deviations regime

We consider call option prices close to expiry in diffusion models, in an asymptotic regime (“moderately out of the money”) that interpolates between the well‐studied cases of at‐the‐money and out‐of‐the‐money regimes. First and higher order small‐time moderate deviation estimates of call prices and implied volatilities are obtained. The expansions involve only simple expressions of the model parameters, and we show how to calculate them for generic local and stochastic volatility models. Some numerical computations for the Heston model illustrate the accuracy of our results.

我国区际产业转移与对接机制研究

区域协调发展理念下,区际产业转移与对接是促进产业结构调整升级的重要手段。基于区际产业转移与对接内涵、动力机制等既有研究,从考虑运输成本的“推-拉”模型与异质性企业区位选择效应的市场动力机制,以及信息不对称下强弱势政府间竞争博弈机制两个维度,剖析我国区际产业转移与对接内在机理。从创新顶层设计、发挥比较优势、降低交易成本3个方面探讨了促进区际产业转移与对接的政策保障措施。     

Does garbage pricing increase the immoral disposal of household waste?

Some empirical studies have attempted to clarify the mechanism of illegal dumping by examining the degree to which per-bag pricing plays a role. However, previous research on the behaviour of avoiding paying a charge for waste collection has tended to neglect so-called ‘immoral disposal,’ which is less risky than illegal dumping because there is no legal penalty. In this study, we define immoral disposal as the dumping of waste in a manner that is immoral but not illegal. To detect the existence of immoral disposal, we apply a spatial econometric approach, namely an extended panel spatial Durbin model, to identify the actual spillover effect of garbage pricing in neighbouring municipalities on immoral disposal from the total waste. A major finding of this study is that immoral disposal exists in unit-based pricing, two-tiered pricing, and fixed pricing.     

国际人才流入是否影响我国FDI区位选择

根据相关经验研究及理论模型可知,国际人才流入可通过降低国际贸易壁垒提高贸易自由度。利用2006-2013年中国内地29个省市面板数据,实证分析了国际人才流入对FDI区位分布的影响。结果显示,国际人才流入与地区FDI水平显著正相关,但国际人才流入对FDI区位分布的影响存在一定区域差异。同时,国际人才流入与企业经营环境及地理集聚水平之间存在某种替代效应,即国际人才流入能够在一定程度上弥补由于企业经营环境缺失和地理集聚水平低下带来的负面影响。此外,良好的企业经营环境和较高的地理集聚水平也对FDI区位分布具有重要影响。上述结论对于我国进一步提升外商直接投资国际竞争力及促进我国FDI区域分布平衡具有重要理论参考价值,同时也对其它新兴发展中国家具有启示作用。     

科技人才集聚对中国区域科技创新效率的影响

基于2005-2015年省际面板数据,构建超越对数随机前沿距离函数模型,借鉴产业区位熵思想,研究科技人才集聚对中国区域科技创新效率的影响。结果表明,科技创新效率存在区域差异,东部地区高于中部、西部、东北地区,西部最低;科技人才集聚规模和均衡度与区域科技创新效率显著正相关,强度与区域科技创新效率显著负相关。鉴于此,为提高区域科技创新效率、缩小区域差异,我国政府应全方位培育并吸引科技人才,合理引导科技人才流动、整合科技人才资源。     

不同类型技术进步的节能减排绩效及其动态变化

运用非参数SML生产率指数模型,测算了1994—2014年中国35个工业行业的基于绿色增长的技术进步,并采用面板模型对按能耗与碳排放分组的行业分别进行能耗强度和CO_2排放强度回归。结果表明:生产前沿的科技创新是推动中国工业绿色全要素生产率提高的主动力,前沿科技创新的节能降耗绩效最高,纯技术效率的CO_2减排绩效最高;技术进步的节能降耗效应与CO_2减排效应具有非对称性,技术进步的CO_2减排绩效大于其节能降耗绩效;能源消费结构调整的CO_2减排绩效大于其节能降耗绩效。     

国家级经济技术开发区发展绩效区位因素研究

国家级经济技术开发区（以下简称经开区）是推进我国工业化和外向型经济发展的重要载体。由于集聚了较多加工制造活动,与生产成本和交易成本相关的区位因素都可能影响经济绩效。基于经开区产业活动区位选择特点,结合106个国家级经开区2013年面板数据作因子分析和多元回归分析,探讨了各区位因素对经开区发展绩效的影响。研究显示,与交易成本相关的区位因素对经开区绩效的影响更显著,这不仅表现为工资、地价和排污费等与生产成本直接相关的区位因素与经开区单位面积产值呈负相关关系,而且表现为交通运输条件和政府依法行政状况等与交易成本相关的区位因素与经开区绩效呈明显的正相关性。因此,为促进经开区持续健康发展,地方政府要改变以往为节约生产成本在要素方面竞相压价和盲目比拼财税优惠政策的行为,加大重视抑制交易成本的上升。     

Carbon pricing and terms of trade effects for China and India: A general equilibrium analysis

Using country-specific dynamic computable general equilibrium (CGE) models, this paper estimates carbon prices in China and India, and compares the effects of carbon pricing policies under terms of trade effects. Estimated carbon prices are higher in China due to differences in emission intensity and in the rate of deployment of new technologies in the models. Differences in carbon prices open up the possibility of carbon trading between the two countries to achieve mitigation objectives. Further, under assumptions about different exchange rate regimes and international fossil fuel prices, the effects of carbon pricing policies on the two economies are mostly similar in terms of direction but, expectedly, different in terms of magnitude. Terms of trade effects could exacerbate carbon pricing effects to a greater degree in China as the country is significantly more dependent than India on external trade and investment. Policymakers should factor in terms of trade effects while designing or evaluating carbon pricing policies in the two countries.     

风险投资、内部控制与审计定价

文章利用手工收集的风险投资持股及其属性特征数据,基于审计风险的分析逻辑,系统研究了风险投资、内部控制与审计定价之间的内在关系.研究发现:(1)与非风险投资持股公司相比,风险投资持股公司的审计定价显著更低;(2)从属性特征来看,风险投资的控制属性显著降低了审计定价,而联合属性显著提高了审计定价;(3)在抑制审计风险、降低审计定价方面,风险投资持股与内部控制质量存在显著的替代效应.文章研究表明,风险投资持股在审计市场上发挥了显著的治理效应,因而强化风险投资机构的增值服务和监督职能,对于提高上市公司运营效率具有重要的现实价值.
