Three Essays on Firm Responses to Climate Change

January 2020 (has links)
abstract: Evidence is mounting to address and reverse the effects of environmental neglect. Perhaps the greatest evidence for needing environmental stewardship originates from the ever-increasing extreme weather events ranging from the deadly wildfires scorching Greece and California to the extreme heatwaves in Japan. Scientists have concluded that the probability and severity for about two thirds of such extreme natural events that occurred between 2004 and 2018 is contributed by rising global temperatures. Operations management literature regarding environmental issues have typically focused on the “win-win” approach with a multitude of papers investigating a link between sustainability and firm performance. This dissertation seeks to take a different approach by investigating firm responses to climate change. The first two essays explore firm emissions goals and the last essay investigates firm emissions performance. The first essay identifies firm determinants of greenhouse gas (GHG) reduction targets. The essay leverages Behavioral Theory of the Firm (BTOF) and argues for two additional determinants, Data Stratification and Science-Based Targets, unique to GHG emissions. Utilizing system generalized method of moments on a dataset from Carbon Disclosure Project for years 2011-2017, the paper finds partial confirmation for BTOF and support for the two additional determinants of firm GHG emission goals. The second essay is an exploratory study that seeks to understand factors for firm participation in the Science-Based Targets (SBT) initiative by combining both primary and secondary data analysis. The study is a working paper with primary data still needing to be completed. Secondary data analysis begins with a review of the literature which suggested four potential factors: ISO 14001 certification, Customer Engagement, Emission Credit Purchases, and presence of Absolute Emissions Targets. Preliminary results using panel logistic regression suggest that Emissions Credit Purchases and Absolute Emissions Targets influence SBT participation. The third essay seeks to understand whether stakeholder pressure drives firm GHG emissions reductions. This relies on Stakeholder Theory and classification schemes proposed in Management literature to divide stakeholders, based on their relationship with the firm, into three groups: primary, secondary, and public. Random effects estimation results provide evidence for primary and public stakeholder pressure impacting firm GHG emissions. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2020

Operations optimization and contracting coordination for behavioral supply chain with typical social preferences / Optimisation du fonctionnement et coordination de contractualisation dans les chaînes logistiques avec prise en compte des éléments comportementaux

Nie, Tengfei 22 January 2015 (has links)
Cette thèse étudie l’incorporation des préférences sociales typiques, telles que le souci de justice et la réciprocité, dans la chaîne logistique. Les impacts de ces préférences sociales sur la prise de décisions dans la chaîne logistique, sur l’efficacité et la coordination du canal de distribution sont étudiés. Plus spécifiquement, la thèse se focalise sur trois questions essentielles ci-dessous : 1. Qu’est-ce qui différencie un canal conventionnel d’un canal comportemental qui prend en compte la justice et/ou la réciprocité par exemple ? 2. Comment ces facteurs comportementaux influencent-ils la prise de décisions du fournisseur et du distributeur dans la chaîne logistique ? 3. Quels effets ont ces préférences sociales sur la coordination du canal de distribution et sur son efficacité ? Afin de répondre à ces questions, nous développons deux modèles d’opérations comportementales. Nous construisons d’abord un modèle de vendeur de journaux pour une chaîne logistique dyadique avec prise en compte de justice dans un processus de négociation de Nash. Dans ce modèle, un fournisseur joue un jeu de Stackelberg avec un distributeur qui doit faire face à une demande aléatoire. La solution de Nash est utilisèe comme référence de justice pour formellement décrire un compromis perçu comme juste, ce qui constitue une nouvelle manière de traiter la justice dans une chaîne logistique. Ensuite nous étudions un canal de distribution similaire mais où le fournisseur et le distributeur ont une préférence pour la réciprocité et la demande est supposée déterministe. Dans ce modèle, l’impact de l’intention dans une chaîne logistique est étudié pour la première fois. Des analyses approfondies de ces modèles comportementaux nous permettent de tirer des aperçus managériaux intéressants,comme par exemple le fait que le souci de justice joue un rôle important sur la difficulté de coordonner un canal de distribution. Nous avons démontré qu’un canal dyadique avec prise en compte de réciprocité peut être coordonné en utilisant un prix de gros constant, ce qui signifie que le problème de double marginalisation ne se pose pas nécessairement tout le temps. / This thesis studies how to incorporate typical social preferences, such as fairness concerns and reciprocity, into the context of supply chain. The impacts of theses social preferences on the supply chain’s decisions, channel efficiency and coordination are investigated. Specifically, it focuses on three important questions as follows: 1, what are the differences between the conventional channel and the behavioral channel (e.g., fairness-concerned channel and reciprocal channel)? 2, how do these behavioral factors influence the decisions of the supplier and the retailer in the supply chain? 3, what effects have these social preferences on the coordination of the channel and its efficiency? In order to answer these questions, two models of behavioral operations are formulated. A newsvendor model for a dyadic supply chain with Nash bargaining fairness concerns is built first. In this model, a supplier plays Stackelberg game with a retailer who faces stochastic demand. Nash bargaining solution is used as fairness reference to formally depict perceptively fair compromise, which is a new perspective to study fairness concerns in a supply chain. Then a similar dyadic channel in which a retailer and/or a supplier have a preference for reciprocity is investigated, but the retailer is facing deterministic demand. In this model, the impact of intention is studied within the context of supply chain for the first time. Some interesting and valuable managerial insights are drawn by analyzing the two behavioral models. For example, fairness concern does have great impact on the difficulty of coordinating a channel. In addition, the dyadic channel with reciprocity can be coordinated by using a constant wholesale price, which implies that the problem of double marginalization is not necessary to be present all the time.

No. of bitstreams: 1 Dissertação_João Luís Corradini Quaglia_final.pdf: 1105096 bytes, checksum: c1efb596b83ac47821901bd42fe12021 (MD5) Previous issue date: 2014-06-25 / Práticas em gestão de projetos (GP), apesar de amplamente difundidas, utilizadas e pesquisadas, não garantem o desempenho (sucesso) do projeto em suas entregas em tempo e custos conforme planejamento. Observa-se que, apesar do uso extensivo de práticas de GP, falhas em relação ao atendimento do cronograma e orçamento são amplamente relatadas. Portanto, este trabalho tem como objetivo principal analisar a influência das práticas de gestão de projetos e do objetivo de desempenho no Comportamento de Cidadania Organizacional (OCB) da equipe de projetos. As dimensões que compuseram o OCB foram: Ajuda, Iniciativa e Compliance. Para testar a relação entre os fatores de práticas de GP (incipientes ou avançados) e objetivo de desempenho (normal ou desafiador) no comportamento da equipe foi utilizada a metodologia do experimento baseado em cenários (SBRP experiment). A amostra contou com 216 alunos de graduação e pós-graduação em administração. O estudo mostrou que a utilização de práticas em gestão de projetos não influenciou o Comportamento de Cidadania Organizacional da equipe de projetos. Entretanto, o objetivo de desempenho nas dimensões de tempo e custos influenciou o Comportamento Cidadão da equipe de projetos. Além desses resultados, a pesquisa mostrou que características pessoais, como experiência em liderar projetos, influenciou a propensão em aumento do comportamento cidadão mediante uma remuneração adicional. Como contribuição adicional este estudo mostra que existem diferenças de resultados nos diferentes grupos de respondentes (alunos de graduação e pós-graduação em administração), conforme encontrado em outros estudos. A utilização do experimento também foi um diferencial metodológico, em virtude de sua ainda baixa utilização em gestão de operações. Finalmente, este estudo também identificou as principais práticas utilizadas na gestão de projetos. / Practices in project management (PM), although widely disseminated, utilized and researched, do not guaranteee the project performance (success) in their deliveries on time and costs as planned. It is observed that, despite the extensive use of PM practices, failures to meet the schedule and budget are widely reported. Thus, this thesis aims to analyze the influence of PM practices and performance targets on the project team's Organizational Citizenship Behavior (OCB). The dimensions that composed OCB were: Help, Initiative and Compliance. To test the relationship between the factors of PM practices (incipient or advanced) and performance targets (ordinary or challenging) in team behavior, the scenario-based role-playing experiment (SBRP experiment) was used, as research methodology. The sample consisted of 216 undergraduate and post graduate students in business administration. The research showed that the use of practices in project management did not influence the project team’s Organizational Citizenship Behavior (OCB). However, performance targets in time and costs influenced the project team’s OCB. In addition to these results, the research showed that personal characteristics, such as experience as project manager, influenced the propensity for increasing OCB based on additional payment. As an additional contribution this study shows that there are differences in the results for different groups of respondents (undergraduate and post graduate students in business administration), as found in other studies. The use of the SBRP experiment was also a methodological advantage, seeing that is has not been widely used in operations management. Finally, this study also identified key practices in project management.

Decision Makers’ Cognitive Biases in Operations Management: An Experimental Study

AlKhars, Mohammed 05 1900 (has links)
Behavioral operations management (BOM) has gained popularity in the last two decades. The main theme in this new stream of research is to include the human behavior in Operations Management (OM) models to increase the effectiveness of such models. BOM is classified into 4 areas: cognitive psychology, social psychology, group dynamics and system dynamics (Bendoly et al. 2010). This dissertation will focus on the first class, namely cognitive psychology. Cognitive psychology is further classified into heuristics and biases. Tversky and Kahneman (1974) discussed 3 heuristics and 13 cognitive biases that usually face decision makers. This dissertation is going to study 6 cognitive biases under the representativeness heuristic. The model in this dissertation states that cognitive reflection of the individual (Frederick 2005) and training about cognitive biases in the form of warning (Kaufmann and Michel 2009) will help decisions’ makers make less biased decisions. The 6 cognitive biases investigated in this dissertation are insensitivity to prior probability, insensitivity to sample size, misconception of chance, insensitivity to predictability, the illusion of validity and misconception of regression. 6 scenarios in OM contexts have been used in this study. Each scenario corresponds to one cognitive bias. Experimental design has been used as the research tool. To see the impact of training, one group of the participants received the scenarios without training and the other group received them with training. The training consists of a brief description of the cognitive bias as well as an example of the cognitive bias. Cognitive reflection is operationalized using cognitive reflection test (CRT). The survey was distributed to students at University of North Texas (UNT). Logistic regression has been employed to analyze data. The research shows that participants show the cognitive biases proposed by Tversky and Kahneman. Moreover, CRT is significant factor to predict the cognitive bias in two scenarios. Finally, providing training in terms of warning helps participants to make more rational decisions in 4 scenarios. This means that although cognitive biases are inherent in the mind of people, management of corporations has the tool to educate its managers and professionals about such biases which helps companies make more rational decisions.
