基于我国资本市场的历史数据进行实证分析,验证了我国A股市场存在股权溢价且呈现高波动性.并采用行为金融学理论从投资主体、市场、制度三方面分析了我国股权溢价及其高波动性的原因.     

我国资产价格对居民银行储蓄的溢价效应:理论分析及实证检验

本文从投资者的获利动机出发,提出资产价格对居民银行储蓄存在着溢价效应。然后用资本资产定价模型(CAPM)分析其作用机理,并以向量误差修正模型(VECM)检验了该效应在中国资产市场上的存在性,结论为溢价效应同时存在于股票和房地产市场上。若要该效应发挥效力,就需要从金融产品创新、金融监管、金融体系改革等方面着手用力。     

利率双轨制、金融改革与最优货币政策

本文将利率双轨制引入带融资溢价的新凯恩斯DSGE模型,以福利最大化为标准,分析了利率双轨制的效率、利率双轨制的改革以及与利率双轨制相配套的最优货币政策。研究发现,利率双轨制的效率不仅与金融市场的扭曲程度直接相关,更取决于产品市场的扭曲程度。政府应该不断降低产品市场和金融市场的扭曲,直到利率双轨制不再有效率时,再一举取消双轨制才是福利损失最小的。在短期,利率双轨制决定了货币政策主要通过管制利率渠道来传导。溢价比稳态提高时管制利率对溢价偏离做正向反应和溢价比稳态降低时管制利率对溢价偏离做轻微负向反应的相机反应规则,优于单一反应规则。     

新股发行定价的影响因素分析

本文针对目前A股市场的高溢价发行、高市盈率、超高募资现象,分析新股发行定价的影响因素以及高溢价发行对市场所带来的影响.此外,基于统计数据,研究新股发行市盈率的可决因素及可能的发展趋势.     

齐当别模型与股权溢价之谜

一、股权溢价之谜 股权溢价(The Equicy Premium)是指股票收益率大于无风险资产收益率的现象.由于股票的风险较大,市场上大量的风险厌恶型投资者必然会要求以高收益来补偿持有股票所带来的高风险,因此一定程度的股权溢价是正常的市场现象.然而,大量针对不同时期与地区的实证研究表明,股权溢价程度远远超出了标准经济学模型所能解释的范围,这一现象被称之为"股权溢价之谜".     

公共采购溢价现象的成因与启示

从长春高价采购电脑,到苏州购买奢侈监控设备,再到满城风雨的高铁采购案,公众纷纷质疑公共采购产品价格虚高,无形中为公共采购烙上了"天价采购"的印记。然而,天价采购是否一定意味着腐败?为了找到答案,我们通过探讨公共采购中的溢价问题,剖析公共采购中合理溢价与不合理溢价的成因,在做出相应判断后为防止"天价"采购提供可行对策。采购溢价的成因从经济学的角度来看,产品的市场价格取决于该产品的供给和需求。在市场竞争充分的条件下,供给曲线与需求曲线相交而生成的价格被称为市场均衡     

产品滞销

上一期，我们通过“病灶二：溢价空间有限”，对产品开发中因为迎合市场需求，为实现跑量、快销而未能充分考虑到产品本身的市场差异化竞争力，从而造成在既定容积率下，产品物业组合无法实现利润最大化，且存在特点不明冠，造成产品溢价空间有限的情况结合实际案例进行了诊断及医治。

消费者对地理标志农产品支付意愿的实证分析——以盐池滩羊为例

以农产品主销区消费者调查问卷为依据,分析了影响因素对消费者地理标志农产品支付意愿的实际影响。结果表明:消费者对农产品地理标志了解和认知程度仍处初级阶段;受教育程度正向影响购买意愿,反向影响溢价支付意愿;对农产品注册为地理标志了解程度、对农产品口感味道评价正向影响购买意愿和支付意愿;非穆斯林、已婚、羊肉占肉类消费比重正向影响购买意愿,而家庭收入水平、无羊肉忌口、无超市购物去处等则正向影响溢价支付意愿;但性别、年龄、农产品品牌了解程度、地理标志了解程度等均未显著影响消费者支付意愿。     

The price premium of generic to brand-names and pharmaceutical price index

The price premium of generic pharmaceuticals to brand-names is examined under different competitive market situations. The result of this study shows that the number, market share, and the age of both brand-name and generic products have the most explanatory power for explaining the price premium. This study further applies this method to a pharmaceutical price index in order to explain ‘Drug Price Index Perplexities.’     

Public Sector Employment and the Skill Premium: Sweden versus the United States 1970–2012

Swedish census data and tax records reveal an astonishing decline in the aggregate skill premium of 30 percent between 1970 and 1990, with only a modest recovery in the next couple of decades. In contrast, the US skill premium rose by around 24 percent over those four decades. A theory that equalizes wages with marginal products can rationalize these disparate outcomes when we replace commonly used measures of total labor supplies by private sector employment. The dramatic decline in the skill premium in Sweden is the result of an expanding public sector that has disproportionately hired unskilled labor.     

Socially responsible products: what motivates consumers to pay a premium?

The motivation to pay a premium for socially responsible products is partly an expression of consumer concern for the well-being of those involved in the production process. Buying a product with a socially responsible label, and donating to a charity are similarly motivated actions. While there is an extensive literature on the economics of charitable giving that examines motivations to donate as well as on the impacts of labelling on consumer demand, there is little overlap between the two literatures. We bridge these two literatures by investigating whether consumers have heterogeneous motivations for paying a premium. Through a laboratory experiment that auctions coffee with hypothetical socially responsible labels that put different weights on in-kind versus cash transfers, we find that those consumers who prefer an in-kind transfer (paternalistic altruists) are willing to pay a 52.5% price premium over standard coffee. Those who prefer that most of the premium is paid as cash (strong altruists) are willing to pay a 42.5% premium. Finally, those who are indifferent to how the premium is spent by the recipient (warm-glow givers) are willing to pay only a 19.2% premium. We discuss the implications of our results and future research directions.     

城镇消费者对有机农产品的购买意愿分析——以有机大米消费为研究对象

基于对北京市、武汉市城镇消费者对有机大米的消费行为调查,分析了有机农产品溢价购买意愿和边际购买意愿。运用联合分析法研究发现,当前消费者对有机农产品的溢价购买意愿倾向比较低,但边际购买意愿较高,价格过高限制了有机农产品的推广。另外,消费者对有机农产品的认知水平、品牌因素对消费者购买意愿有着重要的影响作用。     

Premium auctions and risk preferences

In a premium auction, the seller offers some “payback”, called premium, to a set of high bidders at the end of the auction. This paper investigates how the performance of such premium tactics is related to the bidders? risk preferences. We analyze a two-stage English premium auction model with symmetric interdependent values, in which the bidders may be risk averse or risk preferring. Upon establishing the existence and uniqueness of a symmetric equilibrium, we show that the premium causes the expected revenue to increase in the bidders? risk tolerance. A “net-premium effect” is key to this result.     

中国国情下的保险费率监管模式选择及影响分析--来自车险市场的经验证据

我国保险监管朝着“放开前端、管住后端”的模式发展,保险费率市场化改革的呼声始终较高。文章以财险市场中市场份额最大的车险为研究对象,基于2001－2014年样本分析了费率市场化与费率水平合理性之间的关系。研究发现,我国车险市场的实际费率水平明显低于理论费率;费率监管的严格程度的确会影响费率水平的合理性,其中适度监管模式下的费率水平最为合理。文章进一步深入探究了费率水平合理性对偿付能力的影响机制,发现费率差异的波动性会通过净利润而间接影响偿付能力。费率差异的波动性越小,净利润越高,偿付能力越强,因此应慎重选择费率监管制度。文章建议我国保险市场应采用适度监管的费率制度,完全放开的费率市场化略显激进,不适合当前国情。这样不仅能使费率水平更加合理,还不会威胁保险公司的偿付能力,从而使保险市场更加健康稳步的发展。     

International knowledge spillovers and wage inequality in developing countries

In this paper, international knowledge spillovers are incorporated in a horizontal innovation model, designed to explain the observed uncertain effects that openness of trade can have on wage inequality in small developing countries. Openness of trade can produce two different effects: an increase in the relative price of less-skilled labor-intensive products and a wider skill discrepancy due to knowledge spillovers from the more to less developed country. The former triggers a fall in the wage premium, while the latter widens the wage premium gap in a developing country. These two opposing forces explain the observed uncertain effects of openness to trade on wage inequality in developing countries.     

Costly investment, complementarities and the skill premium

We propose a new framework to analyse the relationship between the relative high-skilled labour endowment, the skill premium and economic growth. Building on Acemoglu and Zilibotti (2001), we introduce physical capital; internal costly investment in both capital and R&D; and complementarities between intermediate goods. We only find a positive relationship between the relative labour endowment and both the skill premium and economic growth within determined intervals of relative labour endowment values, which vary with the absolute productive advantage of high over low-skilled labour. The model thus accommodates theoretically mixed empirical results on the relative labour endowment-skill premium relationship. We further find that the impact on both the relative labour endowment and the skill premium of a rise in investment costs or in the complementarities degree depends on: (i) the absolute productivity advantage of high over low-skilled labour; and (ii) the relative labour endowment.     

City Size and Wage Disparity in Segmented Labour Market in China

The relation between city size and wage inequality is well established for Western countries. This paper finds that city size–wage premium exists across Chinese cities to a lower extent than the Western world. Further, using a simplified model on the Chinese Household Income Project survey data, we find that the city size–wage premium varies with difference in skills among urban citizens. The variation amounts to 50% more for the high‐skill workers compared with their low‐skill counterparts. Moreover, owing to the presence of segmented labour market, the patterns of city size–wage premium and city size–wage inequality premium are notably different for the migrants, who receive a much lesser wage than the citizens and do not experience wage variation owing to their skill heterogeneity.
