Heterogeneous duopoly with isoelastic demand function

In this paper we analyze a duopolistic market with heterogeneous firms when the demand function is isoelastic (Puu, T., 1991. Chaos in duopoly pricing. Chaos, Solitons and Fractals 1, 573–581.). We consider the same heterogeneous firms of Zhang et al. (Zhang, J., Da, Q., Wang, Y., 2007. Analysis of nonlinear duopoly game with heterogeneous players. Economic Modelling 24, 138–148.) introducing a nonlinearity in the demand function instead of the cost function. Stability conditions of the Nash equilibrium and complex dynamics are studied. In particular we show two different routes to complicated dynamics: a cascade of flip bifurcations leading to periodic cycles (and chaos) and the Neimark-Sacker bifurcation which originates an attractive invariant closed curve. Comparisons with respect to the Puu model and the model of Zhang et al. are performed.

新新贸易理论将企业异质性成功的引入到国际贸易模型中,从微观层面解释了贸易的发生及影响,从而开拓了国际贸易研究的新领域。新新贸易理论解释了为什么好的企业做国际贸易,而较次的企业做国内贸易这一现象,该理论认为,自由贸易可以提高产业生产率水平和社会福利,所以在政策上应该促进自由贸易而不是贸易保护。     

Responding Destructively in Leadership Situations: The Role of Personal Values and Problem Construction

This study explored the influence of personal values on destructive leader behavior. Student participants completed a managerial assessment center that presented them with ambiguous leadership decisions and problems. Destructive behavior was defined as harming organizational members or striving for short-term gains over long-term organizational goals. Results revealed that individuals with self-enhancement values were more destructive than individuals with self-transcendence values were, with the core values of power (self-enhancement) and universalism (self-transcendence) being most influential. Results also showed that individuals defined and structured leadership problems in a manner that reflected their value systems, which in turn affected the problem solutions they generated.     

Gender Differences in Double Standards

The purpose of the present study is to investigate gender differences in the use of double standards in ethical judgements of questionable conduct instigated by business or consumers. We investigate if consumers are more critical towards unethical corporate versus consumer actions and if these double standards depend on the gender of the respondent. In the first study, we compared evaluations of four specific unethical actions [cfr. DePaulo, 1987, in: J. Saegert (ed.) Proceedings of the Division of Consumer Psychology (American Psychological Association, Washington DC)] instigated by either the consumer or the corporation. In a second study, we investigated the perception of some general consumer and corporate (un)ethical actions in addition to DePaulo’s unethical scenarios. Both researches show that females are less likely to use double standards when it comes to their own (un)ethical behaviour compared to corporate (un)ethical actions. Furthermore, gender differences in the use of double standards depend on the type of unethical behaviour. Limitations and suggestions for further research are discussed.     

Interactive effects of consumers’ ethical beliefs and authenticity on ethical consumption and pro-environmental behaviors

The current study examined the relationships of ethical beliefs (i.e., idealism and relativism) with pro-environmental behaviors (direct and indirect) and ethical consumption behavior. The study further examined the moderating role of consumer authenticity in these relationships. Data were collected from individuals (N = 302) using field surveys within three major metropolitan cities of Pakistan. The findings revealed that idealism had a positive relationship with ethical consumption behavior and pro-environmental direct behavior. However, it was not related to pro-environmental indirect behavior. Relativism was positively related to ethical consumption behavior but it was not related to both types of pro-environmental behaviors. Furthermore, consumer authenticity significantly moderated the relationships of idealism with all ethical outcomes. Finally, implications for organizations, marketers and policy makers are discussed.     

Banks’ interconnections and peer effects: Evidence from Chile

In this paper, we identify and quantify the importance of endogenous peer effects in the interbank market, allowing for varying degrees of intensity of these peer effects. We base our analysis on a unique dataset that includes all interbank loans that have taken place between 15 banks in the Chilean interbank market representing more than 95% of the market between 2009 and 2016. This approach contrasts sharply with the geographical definition of peers used by most of the literature. As an application of our model, we examine an episode of liquidity shortage experienced by one Chilean bank in the interbank market, with the lenses of our model. We show evidence consistent with a herding behavior of the lender banks which, according to our model, were peers of the stressed bank.     

异质性资源对企业生态创新的影响——以资源管理为中介

为获取长期竞争优势，企业应充分利用各种资源进行生态创新。基于资源基础理论(RBT)，以资源管理为中介，探讨异质性资源对企业生态创新的影响机理。以406家制造企业为样本，采用偏最小二乘结构方程模型(PLS-SEM)和模糊集定性比较分析方法（fsQCA）进行实证检验。结果发现，内部资源和外部资源均对企业生态创新具有正向影响，资源管理在异质性资源影响生态创新的过程中起部分中介作用。在生态创新二阶模型中，生态管理创新的作用明显优于生态产品创新和生态工艺创新。通过fsQCA进一步发现导致低生态创新的两种前因构型，拓展了资源基础理论在企业生态创新领域的运用，可为我国企业实施和评价生态创新行为提供参考。     

New empirical assessment of export price competitiveness: Industry-specific real effective exchange rates in Asia

This study constructed the industry-specific real effective exchange rate (I-REER) as a new measure of export competitiveness by industry. By aggregating I-REERs to a country-level I-REER for nine Asian economies, we assess the effect of REER appreciation on real exports by employing both static common-correlated effects (CCE) estimator and cross-sectionally augmented distributed lag (CS-DL) estimator (a dynamic version of the CCE estimator) to control for heterogeneity in the impact of unobservable common factors. The degree of REER’s negative effect is found to have declined in recent years, which may imply that growing global value chains (GVCs) tend to mitigate the negative effect of REER appreciation on exports. As is well known that Asia is characterized as active regional trade and investment through GVCs, further regional integration would make Asian economies have less concern about policy coordination for regional exchange rate stability in Asia.     

Product-harm science communication: The halo effect and its moderators

Science communication on a product-harm situation aims to create awareness on the product's potential impacts for consumers. However, consumers tend to overestimate the information provided, due to possible halo effects. Here we designed a contextual model of halo development including individual and message characteristics detected in the literature as potential moderators. Our experimental study, based on a sample of 3,766 European respondents, evaluates these halo moderators in the context of a product-harm science communication. The results reveal a stronger halo effect on consumers' beliefs when the focal topic is considered as more important (health vs. ethics) and simultaneously when the source of information is more credible (official vs. non-official). Highly involved consumers are also subject to greater halo effects. Suggested implications mainly focus on the need to consider potential amplifying halo effects and on the importance of responding to a product-harm communication via a very accurate communication approach.     

Picking Gifts for Picky People

Shoppers report that 39% of their holiday gift-purchases are for someone “picky.” However, despite the ubiquity of shopping for picky people, little research has examined how people choose gifts for picky people. In the present research, we define the “picky gift recipient” as someone perceived to have narrow and unpredictable preferences, and we show how shopping for someone picky alters gift giving behavior. We find that although gift giving norms prescribe that gift givers spend effort, time, and money on gifts to strengthen their social ties, an exception to this rule occurs when a gift recipient is picky. When shopping for someone picky, givers believe that increasing their resources on a gift will not result in greater recipient-satisfaction with the gift itself—a lay belief that ultimately demotivates givers, causing them to spend fewer resources on picky people (even picky friends). That said, we find that consumers are more willing to spend money on superficial gift-features for picky people, such as professional wrapping, to “dress up” their gifts. Based on this preference, we developed and tested a novel promotion strategy that retailers could implement to recoup some of the lost spending by consumers who are shopping for picky people. In all, this research contributes to the literature on gift giving dynamics, and provides insights more broadly into how shoppers negotiate the burden of shopping for someone whom they anticipate will not like their choice.
