有限理性與市場微結構:以代理人基雙方喊價市場為主之個案分析曾仁傑, Zeng, Ren Jie Unknown Date (has links)
在代理人基計算經濟學的研究領域中,有限理性與市場之間的相互關係已有相當多的討論,主要研究範疇是在理性程度高低對市場表現的影響,較少是針對理性程度與個體行為的研究。而且代理人基計算經濟學的本質之一,是在於個體所展現的行為,然而卻顯少看到對代理人行為的深入探討,尤其是因不同理性程度所造成的行為差異。
對於這樣的現象,本文首先提出三個疑問:第一、為何要探討個體的行為?第二、該如何研究個體的行為?第三、哪一種計算智慧工具或演算法才能合理表達個體的有限理性及行為?藉由市場設計觀點及真實市場例子,我們說明了個體行為在市場所扮演的角色和重要性。並透過多重個案的設計來分析討論不同市場型態與不同理性程度對個體行為所造成的影響。同時,透過 GP 的適應性演化運作方式及特性來建構並合理表達代理人的策略化喊價和學習行為。
因此,本文在 Chen and Tai (2003) 的雙方喊價市場架構下,透過分組模擬實驗與多重個案設計,探討增加代理人理性程度對市場效率及交易者策略行為的影響,而主要的核心是著重在深入探索代理人如何演化以及與對手如何共演化其自身的策略行為,還有因不同理性程度所表現出的行為差異。並藉由變動 GP 代理人群體策略大小來表達理性程度高低。對於理性程度與個體行為的探討分成二階段設計來進行:第一階段是針對個人的策略學習行為及因理性程度增加所表現的行為改變,並以第一階段的分析結果為基礎,第二階段進入兩位買方交易者的策略共演化行為,以及雙方理性程度同時增加所展現的策略互動行為。
在第一階段的分析討論中,可以清楚觀察到交易者的學習行為及得到一些策略的共同特性,並且藉由這些特性能了解交易者策略使用背後所隱含的意義及理由,還有觀察到交易者因理性程度增加而進步的學習過程。然而在第二階段的分析討論中,分別採用了直接的策略分析與間接的利潤變化狀態來探討雙方的共演化行為。但所得的分析結果不再是像是第一階段那麼清晰,不過還是能從各多重個案的分析,歸納出一些雙方的互動模式。
最後,藉由 GP 演算法來進行代理人基的建模及模擬實驗與本文所建構的分析策略之結合,可發現一些關於個體行為的知識: GP 策略的共同特性,以及雙方的策略互動行為,還有理性程度對個體行為所造成的影響。同時,也能清楚認知到分析個體行為所會遇到的限制和問題。並確實讓我們對個體行為之研究有更進一步的了解與認識。

Imagineering Place : The Branding of Five Chinese Mega-CitiesBjörner, Emma January 2017 (has links)
Cities, regions, nations and other places have in recent decades become active participants in the global competitive economy, and now operate in a global marketplace, competing with other places all over the world for investors, tourists, residents and workforce. As a result, places use marketing and branding strategies and practices to gain reputation and competitive advantage. Chinese cities have, over the past decades, increasingly engaged in branding activities, and even taken the role of spearheads for China in its positioning in the global economy, seen for example in the organization of mega-events. The branding of Chinese cities nevertheless exhibits some differences compared with city branding in the West. The aim of this dissertation is to contribute to our knowledge of the internal-political aspects of place branding, using field studies of the imagery used in city branding practices in five Chinese mega-cities, namely Beijing, Shanghai, Shenzhen, Chengdu and Chongqing. The focus is on the images and language used in the cities’ branding, and on key political aspects involved in the branding of Chinese mega-cities. The theoretical lens incorporates concepts tied to images, language, imaginaries, ideology and power, and the study relies on an ethnographic, multiple case study approach, including longitudinal fieldwork in China. The findings consist of rich illustrations of the branding of the five Chinese mega-cities, and include an analysis of similar imagery found in all five cities, grouped into economic, international, cultural, social and environmental imaginaries. This shows that city branding in Chinese mega-cities is focused on creating international and competitive cities, while also paying attention to the environment, culture and internal target groups such as residents. A central contribution of this dissertation is the development of the concept ‘imagineering’, used in this study to conceptualize key political aspects of city branding in Chinese mega-cities. Imagineering contains three main elements, namely local adaptations of national directives, policies, plans and concepts; a strong future orientation while also accentuating selected elements from the past; and a focus on local populations with the creation of stability and harmony as a central goal. Imagineering is also conceptualized as a policy instrument exercised by a powerful élite, closely intertwined with urban governance, and used to influence people, values, places and, ultimately, city futures.

Educational pathways and transitions in the early school years : Special educational needs, support provisions and inclusive educationLundqvist, Johanna January 2016 (has links)
The overall aim of this research is to describe and analyse the educational pathways from preschool to school of a group of children with and without special educational needs. The aim is also to describe and analyse children’s views and experiences of early years education, and how these can be obtained. The research comprises six studies that are presented in four articles and two conference papers. Longitudinal and multiple-case study designs, and mixed method approaches are adopted in the empirical studies, and the data is collected via observations, a questionnaire, documents, conversations and interviews with staff, children’s drawings and interviews with children. The results from the empirical studies show a variation of pathways to compulsory education; changes in activities and relationships in the transitions; a variation in preschool quality; a broad conceptualising of special educational needs; an application of comprehensive or specialised typologies in the educational settings; an undecided and cautious attitude toward inclusive education; an allocation of generous resources to specialised and segregated programmes; and a diversity of support provisions. The children report more positive than negative experiences of their early school years and pinpoint the importance of having a sense of belonging among peers; opportunities for creative play and thinking; experiences of speed, excitement and physical challenges; elements of cosiness, withdrawals and comfort for recreation; experiences of growth in knowledge and understanding of the world; feeling safe; feeling free and autonomous; and preventing homesickness in order to thrive. The results of the literature review are that the researchers may obtain data from children with and without special educational needs by means of traditional and innovative data collection methods. For broadening participation and sharing of views, the researchers may offer relational and material support. The thesis has relevance for researchers in the field of special education, inclusive education and early childhood education and care. It has also relevance for teacher training, policy makers and stakeholders, school heads, teachers and families. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 6: Submitted.</p>

L'orientation entrepreneuriale des PME à internationalisation rapide et logiques d'identification des opportunités d'exportation : cas des PME agro-industrielles au Maroc / The entrepreneurial orientation of early internationalizing SMEs and logics of export opportunities identification : case of agribusiness SMEs in MoroccoSabbari, Ahmed 03 July 2015 (has links)
Hormis l'intérêt croissant que suscitent l'entrepreneuriat international et l'entrepreneuriat organisationnel comme nouvelles voies de réflexion, la recherche académique dans les deux champs ne semble pas suffisamment insister sur les processus et les dynamiques sous- jacentes de l'internationalisation rapide des PME et de la formation de leurs orientations entrepreneuriales (OE). La présente recherche se donne comme objectif de proposer une compréhension systémique des processus entrepreneuriaux de la PME à internationalisation rapide en plaçant la logique de identification des opportunités d'exportation au cœur de notre réflexion. Le travail s'achèvera par une modélisation qualitative expliquant le phénomène en question.La première partie de cette thèse est consacrée aux fondements théoriques de la recherche, abordant les concepts clés de notre cadre conceptuel. La deuxième partie aborde empiriquement la problématique de la recherche. Après une première analyse de contextualisation, sont présentés et analysés les résultats d'une étude de cas multiples, réalisées au sein de six jeunes PME exportatrices marocaines du secteur agro-industriel.La recherche met en évidence des vecteurs internes (connaissances, expériences et capital social) et des contraintes externes (nature de l'activité et caractéristiques du marché local) comme déterminants de l'internationalisation rapide des PME étudiées. Plus important encore, deux configurations différentes de l'OE sont décrites en relation avec deux logiques distinctes de identification des opportunités d'exportation (une logique de type causale et une autre de type effectuale). / Despite the growing interest in international entrepreneurship and organizational entrepreneurship as new ways of thinking, academic research in both fields does not seem sufficiently emphasize the underlying processes and dynamics of the accelerated internationalization of SMEs and the formation of their entrepreneurial orientation (EO). This research aims to provide a systemic understanding of entrepreneurial processes of the SMEs by placing the logic of determining export opportunities at the heart of our thinking. The work will conclude by a qualitative model explaining the phenomenon in question.The first part of this thesis is devoted to the theoretical foundations of research, addressing key concepts of our conceptual framework. The second part addresses the problem of empirical research. After an initial work of contextualization, are presented and analyzed the results of a multiple case study, conducted in six young Moroccan exporting SMEs in the agro-industrial sector.The research highlights the internal vectors (knowledge, experience and social capital) and external constraints (nature of the activity and the local market characteristics) as determinants of the accelerated internationalization of young SMEs studied. More importantly, two different configurations of the EO dimensions are described in relation with two distinct logics of determining export opportunities (causal logic vs effectuale logic).

What are the Critical Success Factors of Start-Ups in the Digital Transformation? : A multiple case-studyTischlinger, David, Van Wordragen, Bas January 2019 (has links)
Throughout the last years, we have been able to experience one of the most significant economic disruptions in history: The Digital Revolution. In a world that becomes more and more digitalized, companies must get an understanding of the fundamental rules of doing business in the digitalized business world in order to be able to innovate effectively and succeed with their business. The purpose of this paper is to get an in-depth understanding on how the digitalization affected the dynamics of doing business, and what the necessary key components are according to the literature and interviewees to succeed as a business in the digital era. Our contribution to the theory is achieved by conducting a multiple-case study in which eight case companies were selected and interviewed via semi-structured interviews. Subsequently, a grounded analysis was conducted to identify the subjective success factors of the interviewees which resulted in five major themes which contribute significantly to a firm’s success. We came to the conclusion that the main success factors for Start-Ups in the digital transformation are: 1. Lean Approach to Customer Orientation, 2. Entrepreneurial Goals & Culture, 3. Participation in the Entrepreneurial Ecosystem, 4. Integration & Utilization of Third-Party Technologies, and 5. Acquisition of Capital for Business Growth.

Collaborative Supply Chain Performance Measurement Systems : A multiple case study on the OTD-process of manufacturing SMEs in the Swedish lighting industry / Collaborative Supply Chain Performance Measurement Systems : A multiple case study on the OTD-process of manufacturing SMEs in the Swedish lighting industrySvensson, Arvid, Gustafsson, Frida, Guillaume, Julien January 2019 (has links)
Title: Collaborative Supply Chain Performance Measurement Systems. A multiple case study on the OTD-process of manufacturing SMEs in the Swedish lighting industry. Authors: Arvid Svensson, Frida Gustafsson and Julien Guillaume. Background: Even though the multiple stated benefits of Supply Chain Performance Measurement Systems (SCPMS) to enhance the collaboration, there is a lack of research, especially regarding the presence among Small and Medium-sized Enterprises (SME). Closely associated with the presence of a SCPMS are the challenges. Research on SCPMS and the accompanied challenges have been made in multiple fields and contexts. Yet, SCPMS in the Order to Delivery (OTD)-process between a SME lighting manufacturer and their key customers is missing. Purpose: The purpose of this thesis is to investigate to what level collaboration regarding SCPMS is present in the OTD-process among the cases studied as well as explain this level of collaboration by studying the challenges of SCPMS. The aim is to contribute to existing literature with an explanatory model that highlights the challenges for a highly collaborative SCPMS with their key customers. This model should also give practical contributions to the case companies. Method: A multiple case study have been conducted. Qualitative data has been gathered through semi-structured interviews. Findings and Conclusion: The findings show that the level of collaboration in the SCPMS differs from no presence at all to an almost total high presence in the cases studied. The criteria that were found in previous literature for high collaboration in the SCPMS were overall similar to the practices found in the cases. Most of the challenges found in previous research were able to explain the difference in level of collaboration in the SCPMS. The two major challenges were lack of knowledge and lack of will. Lack of knowledge was present where the will to progress was clear, while also in one case, there was not even a will to progress. Overall, the company with low level and will to progress was most likely to perceive challenges, while the company with the highest level perceived the least challenges.

Análise da gestão de ideias de produtos para apoiar o planejamento da inovação / Analysis of the product idea management to support the front-end of the innovation processCunha, Vitor Pinheiro 23 September 2011 (has links)
Organizações têm de lidar com um ambiente dinâmico em que a inovação é essencial para o sucesso dos negócios. Além disso, a capacidade de inovar em produto de qualquer organização está diretamente relacionada a um fluxo contínuo de novas ideias capazes de atender às oportunidades de novos produtos e tecnologias. Apesar do seu papel importante no início do processo de inovação, ao contrário de tentar gerenciar o surgimento de novas ideias, a abordagem mais comumente preconizada pelas empresas é de incentivar a geração de um grande número de ideias. No entanto, o sucesso do desenvolvimento de novos produtos requer mais do que gerar ideias, outras características do processo devem ser consideradas. Para ajudar na compreensão dessas características, essa pesquisa tem como objetivo analisar como o processo de gestão de ideias de produtos é realizado nas empresas. Para atingir esse objetivo, primeiramente, é proposto um modelo conceitual síntese da gestão de ideias baseado nas características identificadas literatura. Em seguida, para compreender o comportamento dessas características na prática, é realizado um estudo de casos múltiplos em 15 empresas reconhecidas como inovadoras e de diversos setores da indústria. Por fim, baseado nos dados levantados nas empresas, as características do processo de gestão de ideias são analisadas e confrontadas com as informações obtidas na revisão da literatura. A partir do estudo é identificado que a condução do processo de gestão de ideias pode seguir diferentes lógicas conforme as características das empresas. Certos fatores, tais como: definições estratégicas, formas de condução do processo e fatores organizacionais devem ser levados em conta na definição da melhor forma de gerenciar o processo. Considerando, que os estudos identificados na literatura concentram-se em analisar características específicas do processo, tornando difícil obter uma visão completa do processo, esta pesquisa apresenta uma importante contribuição para a teoria acadêmica por meio da análise das principais características que compõem o processo. Este trabalho apresenta ainda uma contribuição para empresas, pois pode ser utilizado como referência de como o processo vem sendo desenvolvido e fornece uma visão prática de como pode ser estruturada a gestão de ideias. / Organizations have to deal with a dynamic environment in which innovation is essential for success of businesses. Additionally, the product innovation capability of any organization is directly related to a continuous flow of ideas capable of raising opportunities for new products and technologies. Despite the primary role of ideas, instead of managing the ideation process, the most common approach is the generation of a large number of ideas. However, launching new products requires more than just generating ideas, many other characteristics of the process need to be addressed. Thus, to explore these characteristics, this research has as main objective analyze how the product ideation process is carried out in companies. To achieve this goal, firstly, is proposed an ideation conceptual model, based on the synthesis of the characteristics identified in literature. Then, to understand the behavior of these characteristics in practice, is conducted a multiple case study in 15 companies recognized as innovative and from different sectors of industry. Finally, based on data collected, the characteristics of the ideation process are analyzed and compared with the information obtained from the literature review. Based on the results of the study is identified that the conduct of the ideation process may follow different logics according to the characteristics of companies. Certain factors, such as: strategies, ways of conducting the process and organizational factors should be taken into account in defining the best way to manage the process. Considering that the studies identified in the literature focus on analyzing specific characteristics of the process, making it difficult to get a complete overview of the process, this research presents an important contribution to academic theory by analyzing the main characteristics that impact the process. This work also presents a contribution to companies, as it can be used as a reference of how the process is being developed and provides a practical overview of how it can be structured.

Desenvolvimento profissional e relatos de vida de professores de química: um estudo de caso múltiplo / Professional development and life stories of Chemistry teachers: a multiple-case studyBonardo, Josely Cubero 23 April 2010 (has links)
O presente trabalho insere-se numa perspectiva de pesquisa qualitativa. O foco desta investigação recai particularmente sobre a aula de uma professora, Sophia, bem como no grupo de quatro professores que juntamente com ela participaram de um grupo colaborativo, constituindo-se assim, num estudo de caso múltiplo sobre o desenvolvimento profissional num contexto de formação contínua. Nesta investigação objetivou-se estabelecer as relações possíveis entre relatos educacionais e de profissionalização, concepções de ensino-aprendizagem e prática educativa que se evidenciaram num processo de reflexão crítica realizado por este grupo. A base de dados é composta por gravações em vídeo de aulas dentro de um contexto de uma disciplina de pós-graduação, vídeo de uma aula da profª Sophia no seu contexto real de atuação, textos escritos, desenhos e reflexões dos professores e gravação de uma entrevista com cada um desses cinco professores investigados. Os dados foram todos transcritos e a análise dos dados está baseada na análise textual discursiva, onde categorias emergentes foram estabelecidas. Ao final um metatexto foi construído onde o resultado dessas análises está contemplado. O processo reflexivo investigado nesse grupo revela um universo distinto de características de professores e a complexidade do processo educativo. As ações de cada professor em sua prática educativa têm influencias múltiplas e muito diversas relativas ao seu histórico de vida, sua experiência formativa e profissional, suas crenças, suas orientações políticas etc. O que determina a auto-imagem de um professor competente é provavelmente influenciado por todas essas características de uma maneira dinâmica e altamente complexa. Entretanto, duas características marcantes reveladas nesse estudo de caso múltiplo parecem ter influência positiva no trabalho de um professor - sua formação específica e pedagógica além de uma postura de confiança no processo educativo. Essas características nem sempre andam juntas, mas revelaram-se importantes para uma atuação segura dos professores investigados e, portanto, destacam-se no processo de construção de sua autonomia. / This work has a qualitative research perspective. Our focus was the class of an in-service teacher, Sophia, and the four teachers who participated of a collaborative group. This investigation was a multiple-case study about the professional development in a teacher education context. The aim of this research was to establish possible relations between educational and professional reports, teaching-learning theories and classroom practice. These relations were revealed during a critical reflection process which was done by a group of in-service teachers. This research took place within the framework of a post graduation course. Our data are based in class videos, a video of Sophia\'s classroom, written texts, drawings, teacher\'s reflections and interviews with each one of these five teachers. Data were all transcribed and analyzed by the use of discursive textual analysis methodology, which established the emergence of some categories. At the end a metatext was written reporting and discussing the results of such analysis. The reflective process investigated in this group reveals that each teacher contributes with an idiosyncratic universe of characteristics and also evidences the complex nature of the education process. Each teacher actions in their educative practice have multiple and diverse influences which are related to their life history, educational and professional experience, their beliefs, their political orientations, etc. Results suggest that the self image of a competent teacher is influenced by all of these characteristics in a dynamic and complex way. However, two key characteristics revealed in this multiple case study seems to have a positive influence in a teacher\'s work - specific and pedagogical education and a confident view of the education process. These characteristics not always go together but were revealed as important for a confident performance of the investigated teachers. So, these characteristics can be considered as especially important during the construction of the teacher\'s autonomy process.

Exploring Small Business Strategies in Halifax, Nova ScotiaAkindoju, Oluwatoyin Oluremi 01 January 2016 (has links)
Small business owners contribute 39% of Canada's gross domestic product and account for 67% of new jobs created, but only 50% survive beyond the first 5 years of existence. The purpose of this multiple case study was to explore what strategies some small business owners in Halifax, Nova Scotia used to sustain their business operations beyond the first 5 years. The study population consisted of 6 small business owners of professional firms located in Halifax, Nova Scotia who had succeeded in business beyond the first 5 years. The conceptual framework that grounded this study was the systems theory. Data were collected through semistructured interviews, a review of company documents, and archival records. Member checking of interview response data was used to strengthen the credibility of the findings. Based on the methodological triangulation of the data collected and the van Kaam process, themes that emerged after the data analysis were networking, product-advantage, business-centric approach, and human capital. The data and application of the findings from this study may contribute to social change by providing essential strategies for small business owners to ensure business success that could potentially lead to the prosperity of the community and Halifax economy.
