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.

居民风险态度与社会保险参与:来自CHFS的经验证据

利用中国家庭金融调查(CHFS)的微观调查数据,从居民特征的异质性出发,系统地分析了两个问题:居民风险态度的影响因素、居民风险态度对社会保险参与的影响。从个体基本差异、资产、家庭规模、背景风险、安全因素、金融市场了解程度、幸福因素、流动性约束、地区因素、经济信息因素等方面对居民的风险态度进行了分析,特别是首次考察了安全因素、幸福因素和经济信息因素对居民风险态度的影响。结果表明:有安全防范意识、认为社会治安较好、幸福感较强、关注经济信息以及信息来源渠道较多的居民为风险偏好者的概率较大。风险偏好与养老保险、医疗保险参与的可能性呈负相关,与失业保险参与的可能性呈正相关。而风险厌恶则有着相反的影响。     

Cross-border mergers and acquisitions vs. greenfield foreign direct investment: The role of firm heterogeneity

We develop a general equilibrium model with heterogeneous firms to address two sets of questions: (1) what are the characteristics of firms that choose the various modes of foreign market access (exporting, greenfield FDI, and cross-border M&A), and (2) how does the international organization of production vary across industries and country-pairs? We show that the answers to these questions depend on the nature of firm heterogeneity. Depending on whether firms differ in their mobile or immobile capabilities, cross-border mergers involve the most or the least efficient active firms. The comparative statics on industry and country characteristics display a similar dichotomy.     

A Micromodel of New Product Adoption with Heterogeneous and Forward-Looking Consumers: Application to the Digital Camera Category

We develop an empirical model for the adoption process of a new durable product that accounts for consumer heterogeneity as well as consumers forward-looking behavior. Accounting for heterogeneity is important for two reasons. As the mix of consumers with different preferences and price sensitivities could change over time, firms need to update their marketing strategies. Further, it allows for a variety of shapes for the aggregate adoption process over time. As prices for durable and technology products fall over time with firms continually introducing enhanced products, consumers may anticipate these prices and improvements and delay their purchases in the product category. Forward-looking consumers optimize purchase timing by trading off their utilities from buying the product and their expectations on future prices, quality levels, and brand availability. Such forward-looking behavior will result in price dynamics in the marketplace as price changes today influence future purchases. And it results in different shapes of the new product sales pattern over time by influencing the time to take-off. We show how the parameters of our model can be estimated using aggregate data on the sales, prices, and attributes of brands in a product category. We apply our model to market data from the digital camera category. Our data are consistent with the presence of both heterogeneity and forward looking behavior among consumers. At the product category level, we are able to decompose the effects of the entry of Sony into primary demand expansion and switching from other brands. At the brand level, we find that there exist several segments in the market with different preferences for the brands and different price sensitivities leading to differences in adoption timing and brand choice across segments. For a given brand, we show how the changing customer mix over time has implications for that brands pricing strategies. We characterize how price effects vary across brands and over time and how price changes in a given time period influence sales in subsequent periods. Model comparison and validation results are also provided.     

Customer segmentation using unobserved heterogeneity in the perceived-value–loyalty–intentions link

Multiple facets of perceived value perceptions drive loyalty intentions. However, this value–loyalty link is not uniform for all customers. In fact, the present study identifies three different segments that are internally consistent and stable across different service industries, using two data sets: the wireless telecommunication industry (sample size 1122) and the financial services industry (sample size 982). Comparing the results of a single-class solution with finite mixture results confirms the existence of unobserved customer segments. The three established segments are “rationalists”, “functionalists” and “value maximizers”. These results point the way for value-based segmentation in loyalty initiatives and reflect the importance of a multidimensional conceptualization of perceived value, comprising cognitive and affective components. The present results substantiate the fact that assuming a homogeneous value–loyalty link provides a misleading view of the market. The paper derives implications for marketing research and practice in terms of segmentation, positioning, loyalty programs and strategic alliances.     

异质性、外资企业生产率与产业集聚

本文采用2000~2007年工业企业数据,系统考察了外资企业与我国地区产业集聚之间的互动促进关系,并从企业规模、控制权性质两个维度分析不同外资企业与产业集聚之间互动关系的路径差异。结果发现:外资企业与地区产业集聚之间的互动促进关系主要是外资企业与其前后关联行业集聚之间的互动促进,外资企业与同行业的集聚并未形成相互依赖、相互促进的关系;外商独资企业与其前后向关联行业的集聚均存在互动促进,且外商独资与其后向关联行业的集聚之间形成的互动促进是外资企业与我国产业集聚互动促进的主要路径;中外合资企业仅与其前向关联行业集聚之间形成稳定的互动促进关系。     

基于星上自适应FEC的卫星数据分发

为了解决卫星数据分发系统中雨衰对下行链路的异构性影响,建立了基于再生转发器和多波束技术的卫星数据分发系统简化模型,提出了采用星上自适应分组级FEC（Forward Error Control）的下行链路差错控制方法,针对下行链路的降雨等级自适应选择纠错码率,在不占用上行共享链路的情况下,实现对下行链路差错控制的动态调整,给出了采用RSE码的星上自适应FEC的算法公式,通过MATLAB软件和端到端的FEC技术进行了仿真比较分析,结果表明,当下行链路降雨率小于50%时,网络吞吐率可提高12%~25%。该策略可以为多波束宽带卫星数据分发系统的设计提供参考。     

税收优惠对企业创新的影响——基于先进制造业企业的实证分析

正确评价税收政策对先进制造业企业创新的影响具有重要意义。以2010—2019年中国A股先进制造业上市公司为研究样本,实证考察税收优惠与先进制造业企业创新的关系。研究发现：税收优惠对于先进制造业企业的创新具有激励效应,与所得税优惠相比,增值税优惠激励作用更为明显;区域异质性分析发现增值税优惠激励先进制造业企业创新呈现中、东、西部递减的状态,所得税优惠激励创新呈现东、西、中递减的状态。为提高税收优惠政策对于先进制造业企业创新的激励效应,提出完善税收优惠政策的建议。     

ESG表现对企业财务绩效的影响研究

ESG已成为衡量企业表现的重要指标。研究企业ESG评级对企业绩效的影响,有利于激发企业的ESG意识,使企业积极承担ESG披露责任,弥合投资者与企业的信息不对称。构建固定效应模型,以2010—2020年A股上市公司为研究样本,对企业污染程度的异质性、企业性质、区域发展程度等进行进一步测试,考察企业ESG评级与企业财务业绩的关系及信息透明的机制效应。实证表明：(1)良好的ESG性能对企业业绩有直接的促进作用;(2)企业信息透明度为其机制;(3)ESG表现与企业绩效的关系受企业污染程度、企业性质、区域经济发展水平的影响,低污染、非国有、东部地区及非省会城市企业ESG评级更能显著提升企业绩效。根据以上结论,本文同时提供决策可借鉴的经验。     

异质性、机构投资者与会计稳健性

以2000—2011年沪深A股上市公司为样本,基于企业本身和市场异质性的视角,考察机构投资者持股对会计稳健性的影响,结果发现：机构投资者持股比例的提升会导致企业会计稳健性的下降,在国有企业、成长性较好的企业中这种负向关系增强了,而企业所处地区的市场化程度对机构投资者持股与会计稳健性之间的负向关系无显著影响,此外,相比“压力抵制型”机构投资者而言,“压力敏感型”机构投资者持股比例的上升导致会计稳健性下降更快。
