The contractionary effects of tax shocks on productivity: An empirical and theoretical analysis

I analyze the effects of tax policy changes on US Total Factor Productivity. VAR estimates show that permanent and exogenous tax increases have strong, permanent, and negative effects on TFP which represent about 80% of change in output following the tax increase. I then build a DSGE model which has learning-by-doing and endogenous TFP evolution. The benchmark model is able to replicate the empirical impulse responses. However, when I calibrate the model as in the literature, the effect of taxes on TFP is substantially less elastic than in the data. I argue that this divergence may arise because tax changes labeled as exogenous can give spurious results or because of a mis-specified model.     

创业导向对创新绩效的影响:顾客授权与开放式创新视角

开放经济下企业往往利用开放式创新范式进行技术创新。从开放式理论视角探讨创业导向对创新绩效的作用机制,重点探讨顾客授权的调节作用。以开放式创新为中介变量,以顾客授权为调节变量,构建一个被调节的中介作用模型。采用259家制造业企业的调查问卷数据检验研究假设,结果表明:开放式创新部分中介了创业导向与创新绩效间关系,顾客授权正向调节创业导向与开放式创新间关系以及开放式创新与创新绩效间关系,顾客授权与创新绩效呈正相关关系。最后,提出了管理建议和未来研究方向。     

Creating competitive advantage: Linking perspectives of organization learning,innovation behavior and intellectual capital

Drawing on learning theories and the intellectual capital (IC) theory, organizational learning research has discussed the benefits of searching for market opportunities and maintaining a competitive advantage in dynamic environments. To explain organizational performance and survival, the previous literature has focused mainly on what organizations do, but it has failed to address how and what they should do. This study argues that if hotel management is open-minded about exploratory and exploitative learning, it can open the door to capturing opportunity and competitive advantage through increased innovation behavior and human capital accumulation. Further, IC theory has also confirmed that social capital and relational capital will strengthen the relationship between innovation behavior and human capital. This study analyzes data from 595 hotel managers and finds strong support for the proposed hypotheses.     

The effect of motivational orientation over arousal-shopping response relationship

This paper enlarges extant theory on environmental retail by providing evidence that motivational orientation moderates the relationship between arousal and response. Our conceptual model focuses on the phenomenon of motivational orientation as moderator on the relationship between arousal and shopping intention. We extend Kaltcheva and Weitz model, since their focus was on the association between arousal and pleasure. We measured shopping behavior, as consequence variable in the framework, in six different formats (e.g. satisfaction, loyalty, money $, minutes, products). We did four studies in a 2×3 design with motivational orientation (hedonic vs. utilitarian) and arousal (high vs. moderate vs. low levels). After the procedures, the questionnaire listed the scales. The four studies did provide enough evidence that motivational orientation moderates the relationships proposed by Mehrabian and Russell's theoretical framework and those ones proposed by our model.

Nonparametric learning rules from bandit experiments: The eyes have it!

How do people learn? We assess, in a model-free manner, subjectsʼ belief dynamics in a two-armed bandit learning experiment. A novel feature of our approach is to supplement the choice and reward data with subjectsʼ eye movements during the experiment to pin down estimates of subjectsʼ beliefs. Estimates show that subjects are more reluctant to “update down” following unsuccessful choices, than “update up” following successful choices. The profits from following the estimated learning and decision rules are smaller (by about 25% of average earnings by subjects in this experiment) than what would be obtained from a fully-rational Bayesian learning model, but comparable to the profits from alternative non-Bayesian learning models, including reinforcement learning and a simple “win-stay” choice heuristic.     

Passive learning: a critique by example

In models of learning by experimentation that exhibit signal dependence, a benchmark using a passive learner has been proposed. The use of this benchmark is flawed – first, passive learning does not disentangle the effects of knowing that beliefs, as well as other state variables, might change, and we address this issue directly by introducing a naïve learner. Secondly, and more tellingly, passive learning does not do what it is supposed to do, namely help measure the gains from active experimentation; the naïve learner enables us to illustrate this point in the context of a particular example.     

二语词汇习得过程研究

词汇是二语学习的一项重要内容。学习者在二语词汇学习过程中必然会受到母语学习策略、母语认知和母语思维的影响。在词汇学习过程中,二语学习者要逐步减少对母语的依赖,逐渐适应二语词与概念的直接对应复习并运用所学词汇,对词汇信息进行深入全面的加工,培养二语词汇能力。     

省联社管理及其对农信社效率提升的影响:理论与实证研究

合理地衡量和评价省联社对农信社效率的影响,是推动省联社改革的基础,也是当前理论和实践中面临的难题。本文在对省联社的管理服务职能详细调查的基础上,提出了通过比对省联社管理导向和农信社效率提升方向之间的差异,间接分析省联社管理对农信社效率的影响,并以2010-2017年A省75家农信社为研究对象进行了实证分析。研究结果表明,当前省联社管理的总体导向是:有效引导农信社在扩大业务规模的同时,控制总成本收入比和降低不良贷款水平,但对农信社的利润水平、风险覆盖水平、支农支小情况缺乏实质性约束;在推动农信社改制为农商行的过程中缺乏对其提高经营效率的帮助,在管理中未充分考虑各家农信社及其所处市场环境的差异等。文章建议,当前省联社改革的路径是“减少管理+增强服务”,其中减少管理的关键是解决退出职责谁接管的问题,而增强服务的关键是对省联社进行更有效的激励约束。     

外部研发合作广度与新产品开发绩效：一个有调节的中介模型

基于企业外部合作伙伴分布广泛的特点,从外部研发合作广度的两个维度（市场广度和研究广度）出发,选取2010—2018年160家中国制造业上市企业数据,运用多元回归分析法探讨外部研发合作广度对企业新产品开发绩效的影响。结果表明,外部研发合作的市场广度和研究广度正向影响新产品开发绩效,其中,研究广度的作用更为显著;网络学习在外部研发合作广度对新产品开发绩效的影响机制中存在部分中介作用;知识库同质性正向调节外部研发合作广度与网络学习的关系。结论丰富了新产品开发绩效前因变量研究,对企业制定外部研发合作战略,提升新产品开发绩效具有重要管理启示。
