Choice modelling with search and sort data from an interactive choice experiment

We present a highly structured, online, interactive choice environment containing a large number of alternatives, a search tool that eliminates alternatives that fail specified criteria, and a sort tool. A conceptual framework is developed that links tool usage and preference heterogeneity, and tested in the context of long-haul flight choice. Individuals who sort on price are more price sensitive; individuals who search on certain attributes have a greater marginal (dis)utility for that attribute; and individuals who perform certain non-price searches have a lesser price disutility. The method shows promise as a means for providing a richer picture of preference heterogeneity.     

Tradable travel credits for congestion management with heterogeneous users

This paper carries on the recent work of Yang and Wang (2011) on tradable credit schemes by considering heterogeneous users with different value of time (VOT). Given a tradable credit scheme, the user equilibrium (UE) and market equilibrium (ME) conditions with heterogeneous users are formulated into a variational inequalities (VI) problem. Sufficient conditions for uniqueness of the aggregate UE link flows and then the ME credit price are established. Appropriate tradable credit schemes are developed to decentralize system optimal and Pareto-improving network flow patterns. Extension is made to the elastic demand case.     

高管团队异质性、CEO权力与企业成本粘性的实证分析

企业成本粘性正成为实证会计领域一个重要关注的话题,过高的企业成本粘性不利于企业价值极大化。以我国上市公司为样本,对高管特质、CEO权力与成本粘性间的关系进行实证分析。研究发现：团队年龄异质性、教育水平异质性、任期异质性会显著增加企业成本,但专业背景异质性有利于降低企业成本;在考虑CEO权力后,CEO权力的扩大有利于协调高管团队意见,降低成本;其在与高管特质四大因素交互后,团队年龄异质性、教育水平异质性、任期异质性、专业背景异质性受到了削弱或强化。要降低企业的成本粘性,应多注意团队成员的年龄差异、高管的受教育水平、任期以及团队的专业背景;同时也要重视对CEO的赋权,除重视与考察其个人履历与能力外,还应通过契约的方式赋予其管理企业更合适的权力。     

PERSONALITY TRAITS AND THE PERCEPTION OF MACROECONOMIC INDICATORS: SURVEY EVIDENCE

I examine the determinants of both perceived inflation and unemployment in one single survey and include Big Five traits in the analysis. This is the first survey on this topic in Germany. My sample consists of 1771 students from different fields and levels. Using PhD students’ estimates as a reference, I create categories for underestimation and overestimation of both variables. Multinomial logit regressions show that females overestimate both variables. Education and news consumption reduce misestimation. A higher level of Neuroticism is related with a higher probability to overestimate unemployment. Overstating (understating) one indicator is associated with overstating (understating) the other.     

人口老龄化影响居民消费水平的地区异质性分析——来自省际面板数据的经验证据

文章在全国各地区人口与消费统计数据的基础上,将人口老龄化作为影响因素引入消费函数面板模型中,实证判断各地区人口老龄化与居民消费的显著影响关系,得到结论：地区老年抚养比的增长,均会引起大部分地区平均消费倾向的下降,根据影响程度不同,各地区大致可分为三大类：老龄化严重影响居民消费、老龄化显著影响居民消费以及影响不大地区。文章给出了相应的解释,并得出启示：面对老年社会到来这个现实,要想人口老龄化不成为抑制消费的重要因素．需要大力发展社会经济,加强居民的社会保障,提高居民收入,为人口进入老年行列提供强大的经济后盾。     

Location choices under strategic interactions

We explore a fundamental aspect of firms' location choices largely overlooked in the literature: strategic interaction. We formalize the notion that strategic interaction renders collocation less appealing by fostering competition, which erodes firms' profits. Strategic interaction also impacts location choices across time. Specifically, because firms learn by doing in markets, location choices are shaped by two novel effects: entrenchment benefits from entering early in a market and improving capabilities relative to rivals, and opportunity costs from postponing entry to other markets where rivals enter and learn. When learning is local, firms collocate more: rivals are preempted from improving relative capabilities in higher‐value markets. However, when learning is global, firms collocate less: they can transfer capabilities from lower‐value to higher‐value markets, blocking rivals from achieving entrenchment benefits.

Adaptive capacity to technological change: A microfoundational approach

Research summary> : W e take a microfoundational approach to understanding the origin of heterogeneity in firms' capacity to adapt to technological change. We develop a computational model of individual‐level learning in an organizational setting characterized by interdependence and ambiguity. The model leads to organizational outcomes with the canonical properties of routines: constancy, efficacy, and organizational memory. At the same time, the process generating these outcomes also produces heterogeneity in firms' adaptive capacity to different types of technological change. An implication is that exploration policy in the formative period of routine development can influence a firm's capacity to adapt to change in maturity. This points to a host of strategic trade‐offs, not only between performance and adaptive capacity, but also between adaptive capacities to different forms of change . Managerial summary : W hy are firms differentially effective at adapting to technological change? We argue that firms differ in the adaptive capacity of the routines that underlie their capabilities. These differences arise well before change occurs, and result because firms build routines that are differentially responsive to signals of performance decline associated with technological change. Thus, early managerial efforts to build superior productive efficiency must be complemented by efforts to build superior adaptive capacity. Our theory suggests that managers can prepare for technological change by implementing policies, in the formative period of organizational development, that promote individuals' exploration of novel actions. However, there are trade‐offs because preparation aimed at building adaptive capacity to one type of technological change may limit adaptive capacity to other types of change .

大型研发企业的研发投入分析——基于全球前2000家企业研发投入数据

利用2006年全球研发投入居前2000位的企业数据,考察了这些企业研发投入的一些基本特征,如产业分布、国家分布,以及研发的集中度,并探讨了企业研发投入与企业规模之间的关系。研究结论是：研发具有产业异质性;研发在一些国家集中;企业研发的总量水平、研发比率、研发增长率与企业规模具有非线性关系．中型企业具有较高的研发投入量,而小型企业与大型企业具有较高有研发投入比,以及研发增长率。     

上市公司高管团队特征与R&D投资研究

以中国上市公司1999～2006年的研发数据为样本,从公司高管团队人口特征和团队的异质性两个维度。实证检验了样本公司高管团队特征对公司R＆D投资强度的影响。结果发现,高管团队规模、团队平均受教育水平、平均任期都与公司研发投资强度之间显著正相关,团队的平均年龄与公司研发投资强度之间显著负相关。并且发现,控股股东类型不同。高管团队特征对公司R＆D投资强度的影响也不同。     

Market response to syndicated loan announcements from high-profile failed and acquiring banks during the global financial crisis

Previous studies that have examined the impact of the 2008 financial crisis on syndicated loans have ignored potential differences between lending banks by explicitly or implicitly aggregating all lenders together and focusing on borrower characteristics. One must jointly consider both borrower and lender to fully understand the complex role of the syndicate during this period. We consider the identity of the lender, with a focus on five major US banks that failed and their five corresponding acquirers. Our results highlight the distinct roles of investment and commercial banks and facilitate an understanding of relationship and transactional-based lending.
