Retail channel price discrimination

This paper examines price differentials of identical items across retail channels. Many consumer packaged goods are sold through both grocery and drug stores. Liquor is unique in that in much of the country there is a third retail channel of distribution, liquor stores. If consumers in each retail channel differ in their willingness to pay for certain items, then sellers can exploit those differences and charge different prices for the same items in each channel. We examine a unique data set of pooled cross sectional retail scanner data on wine to test whether sellers use retail channel to identify heterogeneous consumer market segments and engage in price discrimination. We begin by presenting a model of price discrimination by retail channel along with behavioural assumptions regarding shoppers in each channel. Next we examine sales by retail channel and find persistent price differentials for the same item across retail channel after controlling for sample selection bias and seasonality. Lastly, we estimate the price elasticity of demand correcting for endogeneity and find differences across channel consistent with the price differentials. The extent of price differential, however, differs significantly with respect to price point.

Illiquidity Premium in the MILA

This article analyzes the illiquidity premium in the MILA. Using seven proxies for illiquidity, we find a positive and significant illiquidity premium for our sample. A microstructure bias-free portfolio weighting based on past returns is critical in our finding of an illiquidity premium, which is robust to several methodological changes in our portfolio simulations. We also document that the premium is present only in small and high book-to-market stocks. Nonetheless, when we control for size and distress effects, the difference and significance in risk-adjusted returns between portfolios of high and low illiquidity stocks remains.     

城镇就业市场上劳动力工资扭曲程度测度

本文利用CHIPS2007数据库，基于随机前沿模型对我国城镇就业市场上劳动力的工资扭曲程度进行测度。研究结果表明：（1）在城镇就业市场上，由于工资扭曲现象的存在，劳动力实际获得的工资要比他们的边际生产率低45％～60％；（2）已婚、子女个数较少、本地、拥有失业保险、男性、大中型企业的劳动力工资扭曲程度要低于未婚、子女个数较多、外来、没有失业保险、女性、小型企业的劳动力；（3）中低工资水平的劳动力工资扭曲程度要比高工资水平的劳动力严重，且中低工资水平劳动力工资扭曲程度的方差更大。由此，本文提出推进就业市场的市场化改革，完善就业市场信息网络，从而减轻劳动力工资扭曲程度。     

消费者生活方式与物质主义价值观的相关性研究

本文主要研究生活方式与物质主义价值观的相关关系。基于495位消费者的问卷调查数据，借助因子分析方法，探索出11个生活方式因子，利用这11个因子进行聚类分析，将调查样本划分为5个子市场。随后，用方差分析法分析得出结果：5个子市场在物质主义价值观上有显著性差异，并用最小显著差异法进行两两比较，确认了具有不同生活方式的消费者在物质主义价值观上的差别。     

Markets for information: Of inefficient firewalls and efficient monopolies

In this paper we study market environments where information is costly to acquire and is also useful to potential competitors. Agents may sell, or buy, reports over the information acquired and choose their trades in the market on the basis of what they learnt. Reports are unverifiable – cheap talk messages – hence the quality of the information transmitted depends on the conflicts of interest faced by the senders. We find that, when information has a prevalent horizontal differentiation component, in equilibrium information is acquired when its costs are not too high and in that case it is also sold, though reports are typically noisy. The market for information is in most cases a monopoly, and there is underinvestment in information acquisition. We also show that regulatory interventions, in the form of firewalls, only make the inefficiency worse. Efficiency can be attained with a monopolist selling differentiated information, provided entry is blocked.     

Acceleration effect of intangibles in the recovery of corporate performance after-crisis

This study explores the recovery in the Market Value Added (MVA) of European companies after the recent global economic crisis in 2008–2009. It introduces empirical evidence that intangible-intensive strategy in human and relational capital reinforces speed of the after-crisis correction for companies. Based on a panel dataset of more than 1600 listed corporations this research aims to discover drivers of Market Value Added trends in 2011–2013. The established results contribute to the understanding of the advantages that companies can exploit for the recovery after systematic shocks of markets. Our study demonstrates that intangible-intensive strategy not always enabled faster recovery speed. Meanwhile, it provided year-to-year acceleration of MVA growth after crisis.     

中国制造业的市场集中、地理集聚与企业绩效

本文研究我国制造业的市场结构与地理分布对企业全要素生产率的影响.以中国工业企业数据库的大样本数据为基础,采用LP法计算企业生产率,构造市场集中度指标和地方化经济、城市化经济两个集聚指标,进行了多方位的计量检验.研究结果表明,制造业的市场集中不利于企业生产率的提高,代表专业化水平的地方化经济促进了企业生产率的提升,度量行业间多样化集聚的城市化经济对企业生产率没有显著的影响.市场集中对出口企业的负面影响不明显,控制市场集中和地理集聚后,出口企业生产率高于非出口企业,出口的“生产率悖论”并不存在.     

A one-sided many-to-many matching problem

This study discusses a one-sided many-to-many matching model wherein agents may not be divided into two disjoint sets. Moreover, each agent is allowed to have multiple partnerships in our model. We restrict our attention to the case where the preference of each agent is single-peaked over: (i) the total number of partnerships with all other agents, and (ii) the number of partnerships that the agent has with each of the other agents. We represent a matching as a multigraph, and characterize a matching that is stable and constrained efficient. Finally, we show that any direct mechanism for selecting a stable and constrained efficient matching is not strategy-proof.     

Granular institutional investors and global market interdependence

We study the propagation of global investment risk across markets through the granular view of institutional investors. Applying the conditional value-at-risk estimation to micro-level weekly observations of international mutual funds between 2003 and 2011, we find that idiosyncratic shocks to large institutional investors explain both aggregate market risk and cross-market risk interdependence. Conditional on the US capital markets being in financial distress, idiosyncratic shocks to the top 10% largest funds investing in the US explain about 40% of the risk fluctuations in other non-US markets. The findings are also economically and statistically significant for the top largest funds investing in non-US markets, with the effects becoming especially large during the global financial crisis of 2007–09. These results are robust after controlling for common risk factors and applying alternative measures of idiosyncratic shocks.
