Action learning and control theory

The essay is a kind of ‘product mix’ of two separate concepts, manifestly quite different but found ultimately to blend into a common message. The author found management literature over the past two decades somewhat difficult to assimilate, due perhaps to an engineering training where problems are always simplified into tangible models and laws. Control theory (or cybernetics), however, seemed to offer a way out of the difficulty, especially as psychologists were using control theory to take them beyond the range of the ‘conditioned reflex’, and the author was encouraged to try out cybernetic ideas in terms of human problems in management and industry. The development of ‘action learning’ as a pragmatic yet sophisticated technique has provided a challenge for the cybernetic model. It is thought that many readers, particularly those with an engineering or scientific background, might find this exposition in social cybernetics helpful in getting a comprehensive grasp of action learning.     

How Does Product Recovery Affect Quality Choice?

We study the impact of product recovery on a firm's product quality choice, where quality is defined as an observable performance measure that increases a consumer's valuation for the product. We consider three general forms of product recovery: (i) when product recovery reuses (after reprocessing) quality inducing components or material (e.g., remanufacturing), (ii) when product recovery does not reuse quality inducing components or material but it is overall profitable (e.g., cell phone recycling), and (iii) when product recovery is costly (but mandated by legislation, e.g., recycling of small appliances in the European Union). Using a stylized economic model, we show that the form of product recovery, recovery cost structure, and the presence of product take‐back legislation play an important role in quality choice. Generally speaking, product recovery increases the firm's quality choice, except for some instances of recovery form (ii). In addition, we find that product take‐back legislation can lead to higher quality choice as opposed to voluntary take‐back. We further demonstrate that both the firm and the consumers benefit from recovery form (ii), while both are worse off with recovery form (iii). However, environmental implications of the three recovery modes differ from their impact on consumer surplus and firm profit. While recovery forms (i) and (iii) reduce consumption and increase environmental benefits, the same is not true with recovery form (ii), which can increase consumption, potentially resulting in higher environmental impact.     

Followers' daily reactions to social conflicts with supervisors: The moderating role of core self-evaluations and procedural justice perceptions

Building on affective events theory (AET; Weiss & Cropanzano, 1996), the present research examined the short-term within-person effects of social conflicts with supervisors at work (SCSs) on followers’ state negative affect (NA) at home. Moreover, it was examined whether personal (i.e., core self-evaluations, CSEs) and environmental (i.e., procedural justice perceptions, PJPs) factors would moderate the SCSs–NA relationship. Hypotheses were tested with a diary study incorporating data from 98 civil service agents over five consecutive working days. Hierarchical linear modeling revealed that on the daily level, SCSs were related with employees’ NA before bedtime. Furthermore, results provide support for the moderating role of CSEs and PJPs in the SCSs–NA relationship. These findings show that the detrimental effects of SCSs are not restricted to the work context but spillover to employees’ private lives and help us to understand when SCSs are particularly detrimental for employees.     

AN ANALYSIS OF PURCHASING COSTS AS THE NUMBER OF PRODUCTS‘ COMPONENTS IS REDUCED

Product design efforts in recent years have focused on standardization and simplification of the product structure. It has been widely argued that savings, tangible and intangible, can be realized by simplifying the product design. In this study, we examine this belief and show that other issues like flexibility of process and design are important as well. We demonstrate that having process flexibility, e.g., of producing a product in two different ways, using two different product structures (as opposed to one), is advantageous with respect to components purchasing costs. This result is in contrast with the notion of standardization since the variety of components in the flexible design is increased. Properties of savings in purchasing costs associated with the use of this flexible design are provided.     

Drivers of private-label purchase behavior across quality tiers and product categories

Private labels hold a substantial share of consumers’ wallets and their popularity is still growing as they spread into various product categories and quality tiers. To determine the right branding strategy, in terms of offering uniform or different private-label brands across product categories, retailers have to know whether consumers use their private-label experience across product categories and private-label tiers. Therefore, we examine different determinants of consumers’ consideration sets. We apply proneness for certain private-label tiers, product categories purchased, purchase frequency, and variety seeking as internal determinants, which contribute to consumers’ knowledge and experience with private labels. Further, we use consumers’ price consciousness and promotion sensitivity as external determinants, which the retailer can use to influence consumers’ consideration sets in the short run. Our analyses are based on large-scale loyalty program data for a period of 24 months. In particular, we use the first 12 months to derive the determinants of consumers’ share of wallets regarding different private-label quality tiers in the second half of the sample. We conduct our analyses for 12 different product categories and aggregate the results by using meta-analytic techniques. Notably, some determinants show dissimilar effects across product categories (e.g., price consciousness and promotion sensitivity), while others (e.g., private-label proneness) are rather similar. We find that consumers’ general proneness for certain private-labels tiers leads to a propensity to purchase them in a specific category and in adjacent quality tiers. Further, we reveal that product category characteristics moderate the determinants of private-label share.     

Emotion cycles: On the social influence of emotion in organizations

Human emotion is typically studied as a within-person, one-direction, non-repetitive phenomenon; focus has traditionally been on how one individual feels in reaction to various stimuli at a certain point of time. But people recognize and inevitably react emotionally and otherwise to expressions of emotion of other people. We propose that organizational dyads and groups inhabit emotion cycles: Emotions of an individual influence the emotions, thoughts and behaviors of others; others’ reactions can then influence their future interactions with the individual expressing the original emotion, as well as that individual's future emotions and behaviors. People can mimic the emotions of others, thereby extending the social presence of a specific emotion, but can also respond to others’ emotions, extending the range of emotions present. People can also draw attributions and extract meanings from others’ emotions. Emotion cycles can involve both intended targets of or partners to an original emotion and third parties who were not the intended targets or partners. Emotion cycles are sensitive to various moderating factors, including demographic variables (e.g., gender or race) and situational variables (e.g., relative power of participants). Pertinent organizational and psychological research that supports the idea of emotion cycles is reviewed and shown to suggest a wide arena for future research.     

Communication About Micropollutants in Drinking Water: Effects of the Presentation and Psychological Processes

This study investigates how people change their risk perception, trust, and behavior as a consequence of being informed about the occurrence of micropollutants in drinking water. Micropollutants are substances present in extremely low concentrations that might be dangerous in higher concentrations. Data were gathered in the city of Zurich, Switzerland in 2013 using a questionnaire in which the information on micropollutants was presented differently to 12 experimental groups. Data of the key constructs were gathered before and after this information, so that causal effects could be quantified by regression analyses. Affective reactions to the information turned out to be the critical mediator of changes in risk perception (operationalized as the perceived change of quality due to pollution), which is an important determinant of changes in behavior and trust. Also, direct effects of affective reactions on behavior and trust were observed. Trust before appraising risks reduces negative affective reactions; however, it also reduces perceived quality (i.e., increases risk perception) and trust after risks are appraised. The different forms of information mainly influenced the participants’ affective reactions, but they also influenced perceived quality. The presentation with the least negative effects was a comparison of the intake of the substance by water with intake by food. The experimental design with repeated measurement that considers trust as a determinant and consequence of risk perception uncovered positive and negative effects of trust before appraising risks on changes of risk perception and trust due to appraising risks.     

Kinship ties and employee theft perceptions in family-owned businesses

Family business research typically views family firms using the frameworks developed for non-family businesses (e.g., agency theory, institutional theory). Thus, using an evolutionary perspective on family may help address gaps in the family business literature, particularly regarding deviance. In the current study, we use kin selection theory to predict that family members receive preferential treatment and this history of privileges can create entitlement and lead genetically-related employees to misuse company resources. Using an experimental vignette methodology and data from 161 people recruited from an online panel, we found that the participants’ purported genetic relatedness to the owner of a business increased their theft intentions and decreased their expected severity of sanctions and likelihood of being reported. Biological sex moderated the relationships between genetic relatedness and theft intentions, as well as between expectations of punishment and theft intentions. Specifically, when females expected higher severity of sanctions or likelihood of whistleblowing, they were less likely to report theft intentions, compared to males. The results of this study suggest that family business owners should protect against theft by all employees, including genetic relatives. Future research using field samples would help provide context for these findings.     

两种激励条件下三级供应链产品质量控制策略研究

本文基于四阶段Stackelberg博弈分析,研究了在三级供应链中如何进行产品质量控制策略问题。构建了由制造商、零售商与最终顾客组成的三级供应链博弈模型,制造商进行产品质量决策,即生产高质量产品或者低质量产品,零售商进行产品采购决策和零售定价决策,最终顾客根据两种产品质量水平和零售价格的差异,决定产品的购买数量;当零售商采购高质量产品时,制造商将会向其提供价格折扣策略;当零售商采购低质量产品时,制造商将会向其提供延迟付款策略。运用最优化原理,求解了制造商的产品质量水平、价格折扣、延迟付款期限和零售商的零售价格、最终顾客的购买数量,及期望收益函数。进行了算例分析,结果表明:高质量产品零售价格关于价格折扣下降幅度更大,而低质量产品零售价格关于延迟付款期限下降幅度更大;制造商提供的价格折扣越大、延迟付款期限越长,其期望收益将会减少,此时零售商的期望收益将会增加,最终顾客产品需求量将会增加;制造商的总期望收益函数将呈现"倒U"型,求解了期望收益的最大值及各契约参数的值,结果证明所提出的产品质量控制策略是可行的。     

Public Response to a Near‐Miss Nuclear Accident Scenario Varying in Causal Attributions and Outcome Uncertainty

Many studies have investigated public reactions to nuclear accidents. However, few studies focused on more common events when a serious accident could have happened but did not. This study evaluated public response (emotional, cognitive, and behavioral) over three phases of a near‐miss nuclear accident. Simulating a loss‐of‐coolant accident (LOCA) scenario, we manipulated (1) attribution for the initial cause of the incident (software failure vs. cyber terrorist attack vs. earthquake), (2) attribution for halting the incident (fail‐safe system design vs. an intervention by an individual expert vs. a chance coincidence), and (3) level of uncertainty (certain vs. uncertain) about risk of a future radiation leak after the LOCA is halted. A total of 773 respondents were sampled using a 3 × 3 × 2 between‐subjects design. Results from both MANCOVA and structural equation modeling (SEM) indicate that respondents experienced more negative affect, perceived more risk, and expressed more avoidance behavioral intention when the near‐miss event was initiated by an external attributed source (e.g., earthquake) compared to an internally attributed source (e.g., software failure). Similarly, respondents also indicated greater negative affect, perceived risk, and avoidance behavioral intentions when the future impact of the near‐miss incident on people and the environment remained uncertain. Results from SEM analyses also suggested that negative affect predicted risk perception, and both predicted avoidance behavior. Affect, risk perception, and avoidance behavior demonstrated high stability (i.e., reliability) from one phase to the next.     

Complexity as a Contract Design Factor: A Human‐to‐Human Experimental Study

Despite being theoretically suboptimal, simpler contracts (such as price‐only contracts and quantity discount contracts with limited number of price blocks) are commonly preferred in practice. Thus, exploring the tension between theory and practice regarding complexity and performance in contract design is especially relevant. Using human subject experiments, Kalkancı et al. (2011) showed that such simpler contracts perform effectively for a supplier interacting with a computerized buyer under asymmetric demand information. We use a similar set of experiments with the modification that a human supplier interacts with a human buyer. We show that human interactions strengthen the supplier's preference for simpler contracts. We find that suppliers have fairness concerns even when they interact with computerized buyers. These fairness concerns tend to be even stronger when suppliers interact with human buyers, particularly when the complexity of the contract is low. We also find that suppliers are more prone to random decision errors (i.e., bounded rationality) when interacting with human buyers. In the absence of social preferences, Kalkancı et al. identified reinforcement and bounded rationality as key biases that impact suppliers' decisions. In human‐to‐human experiments, we find evidence for social preference effects. However, these effects may be secondary to bounded rationality.

消费者品牌忠诚对品牌商再制造市场策略的影响

独立再制造商IR的市场进入给品牌商带来了显著的竞争压力。品牌忠诚源于消费者对某个产品品牌的信任和特殊情感,在产品选择中具有明显的倾向性和排他性,进一步增加了品牌商市场策略的复杂性。针对这一现象,本文采用博弈论结合数值仿真研究了消费者具有品牌忠诚特性下的品牌商再制造市场策略问题。建立并求解了IR不进入且品牌商不再制造（n）、IR不进入且品牌商再制造（nR）、IR进入且品牌商不再制造（nr）、IR进入且品牌商再制造（nrR）四种市场模式,对模型结果进行了灵敏度分析,并探讨了各成员的模式偏好。研究表明：新产品价格、品牌再制品价格、一般再制品价格均与品牌忠诚度正相关;品牌忠诚度的提高一定增大品牌商的利润,但不一定会降低IR利润;当新产品制造成本较高时,品牌商的模式偏好始终为nR$\succ$nrR$\succ$n$\succ$nr,较低时模式偏好受到消费者品牌忠诚度的大小的影响;nr和nrR模式下,品牌忠诚度仅可能提高品牌消费者剩余,但会降低普通消费者剩余、总消费者剩余和社会总福利。     

Newcomers’ reactions to unfulfilled leadership expectations: An attribution theory approach

This paper examines newcomers’ reactions when facing unfulfilled leadership expectations. Although leaders are ascribed a key role in newcomers’ socialization, very little is known about newcomers’ expectations of leadership and their subsequent behaviors when these expectations are not fulfilled. Against the background of a follower-centered perspective, we develop a differentiated model of newcomers’ leadership attributions. As general attribution theory has recently shown, causal links are not always made in clear-cut ways. Thus, there may be several steps between the attribution and non-attribution of leadership. As our qualitative empirical study in Germany reveals, different unfulfilled leadership expectation types lead to equally different leadership attribution levels, with various behavioral consequences for newcomers. We suggest a dynamic model, starting with investing in a relationship before newcomers choose refusing reactions such as confrontation or withdrawal.     

The impact of different fit dimensions on spillover effects in brand alliances

Brand alliances represent a popular business strategy in many industries, because firms hope to evoke positive consumer evaluations of both the alliance’s product and the partner brands. However, extant research offers mixed findings regarding the effects of a brand alliance on its partner brands (i.e., spillover effects). In response, this study separates spillover effects into the effects of the alliance product on the partner brands (brand alliance effects) and the effects between partner brands (brand contrast effects), while also noting the potential moderating impact of perceived attitude- and product-based fit between partner brands on resulting spillover effects. Two experimental studies consistently reveal the existence of brand contrast effects; furthermore, the partner brand’s attitude-based fit reduces undesired brand contrast effects and positively moderates spillover effects in brand alliances, whereas product-based fit does not. Therefore, a third study identifies relevant drivers of partner brand’s attitude-based fit for different brand alliances (i.e., co-branding, ingredient branding, and joint advertising). The findings have notable implications for the design and management of brand alliances.     

Organizational Injustice as an Occupational Health Risk

Abstract

Content to conceive of inequity distress as a hypothetical construct instead of an intervening variable, a half century of research inspired by equity theory has paid little attention to measuring inequity distress. At the turn of the twenty‐first century, however, European epidemiologists, interested in determinants of ill health, found that injustice is a source of adverse emotional reactions that put people at risk for mental and physical morbidity (e.g., depression and coronary heart disease). This research is reviewed here, along with studies identifying pathways accounting for these connections. Specifically, perceived injustices lead to negative emotional reactions and to unhealthy behaviors (e.g., being sedentary, smoking, and drinking excessively), both of which trigger various negative bodily reactions (e.g., elevated serum lipids). These, in turn, subsequently put people at risk of illness. Research has found that such effects are mitigated by organizational interventions that promote perceptions of justice. Three limitations warranting consideration in future research are discussed: (a) the need to address methodological concerns (e.g., reducing common method variance, improving efforts to determine causality), (b) the need to assess the cultural generalizability of research findings, and (c) the need to supplement the existing attention to disease with a new focus on health and well‐being.     

The effects of state-dependent human behavior on the design of a serial line

Most research on line design assumes that human operators perform independently from the status of the line. Recent empirical evidence is contradictory. Humans are likely to change their working speed if they might otherwise cause idle time (Schultz et al., Manage Sci 44(12):1595–1607, 1998). This peculiarity of worker behavior is observed in a variety of settings but little is still known about optimal line design that accounts for this more realistic modeling of worker behavior. Therefore, we analyze work allocation in a serial line with limited buffer capacity and adaptive human behavior. An extensive simulation study reveals that optimal work allocation in state-dependent models is different from classical state-independent models. A bowl-shaped work allocation might be suboptimal and design guidelines are more complicated. Depending on the extent of human reactions, a bowl-shaped, balanced, or reversed-bowl work allocation can be preferable.     

两级供应链产品质量控制契约模型分析

基于博弈论和委托代理理论,研究在两级供应链中如何进行质量控制契约设计的问题。建立生产商和购买商的期望收益函数模型,生产商对其生产过程投资水平进行决策并确定其产品质量预防水平;购买商进行质量评价决策并确定其产品质量检验水平。生产商存在降低其生产过程投资水平的道德风险问题,在生产过程中将"削减投资",购买商为激励生产商提高其生产过程投资水平将支付"信息租金"的成本。购买商在进行产品质量检验决策时,存在夸大产品质量缺陷率的道德风险问题,在产品质量检验过程中将"过度检验"。运用最优化原理,求解生产商的最优生产过程投资水平、产品质量预防水平和价格折扣额与购买商的最优质量检验水平和外部损失分摊比例,并进行了算例分析,结果表明:当生产商提高其生产过程投资水平时,其质量预防水平将显著增加,购买商的质量检验水平将显著下降;随着购买商质量检验水平的提高,生产商所提供的价格折扣额先增大后减少,生产商所承担的外部损失分摊比例将会下降,其期望收益增加,购买商的期望收益将会减少,供应链联合期望收益将呈现"倒U"型,求解了期望收益的最大值及各契约参数的值,结果证明所提出的质量控制契约模型是可行的。     

The Impact of Geographic Proximity on What to Buy,How to Buy,and Where to Buy: Evidence from High‐Tech Durable Goods Market*

Social contagion effects due to geographical proximity refer to the social effects wherein the behavior of an individual varies with the behavior of other individuals who are geographically close. Although the influence of such effects on consumer choices has been established in several contexts, much of the extant studies have focused on its effect on consumers’ decision of whether to buy a new product or adopt a new innovation. There has been no systematic examination of the influence of geographic proximity on other aspects of consumers’ product buying process such as what to buy (i.e., brand choice), how to buy (i.e., the channel), and where to buy (i.e., retailers). Such effects can matter significantly in high‐technology and durable goods markets and therefore, it is critical to understand the scope of these on consumers’ choice of retailers and channel as well. Drawing on literatures from word of mouth effects, ecommerce, and consumers’ perception of risk in their purchase process, we develop a set of hypotheses on the effect of geographic proximity on consumers’ choices of what to buy, how to buy, and where to buy. Leveraging a microlevel dataset of purchases of personal computers, we develop brand‐, retailer‐, and channel‐related measures of proximity effects at the individual consumer level and estimate a joint disaggregate model of the three choices that make up a product purchase process to test these hypotheses. Our results indicate a significant contagion effect on each of the three choices. Furthermore, we find evidence of a greater effect of geographic proximity on inexperienced consumers—those who are new to the product category. Our results thus help develop a holistic understanding of the influence of social contagion effects on consumers’ decision making.     

Applied Nonparametric Instrumental Variables Estimation

Instrumental variables are widely used in applied econometrics to achieve identification and carry out estimation and inference in models that contain endogenous explanatory variables. In most applications, the function of interest (e.g., an Engel curve or demand function) is assumed to be known up to finitely many parameters (e.g., a linear model), and instrumental variables are used to identify and estimate these parameters. However, linear and other finite‐dimensional parametric models make strong assumptions about the population being modeled that are rarely if ever justified by economic theory or other a priori reasoning and can lead to seriously erroneous conclusions if they are incorrect. This paper explores what can be learned when the function of interest is identified through an instrumental variable but is not assumed to be known up to finitely many parameters. The paper explains the differences between parametric and nonparametric estimators that are important for applied research, describes an easily implemented nonparametric instrumental variables estimator, and presents empirical examples in which nonparametric methods lead to substantive conclusions that are quite different from those obtained using standard, parametric estimators.
