EXPECTATIONS IN MACROECONOMICS: PERSPECTIVES, LABORATORY EXPERIMENTS AND AB MODELS

TETTAMANZI, MICHELE 22 December 2017 (has links)
La presente tesi studia le aspettative in macroeconomia contribuendo alla letteratura esistente sia indagando circa il meccanismo di formazione delle aspettative, sia analizzando come le aspettative a razionalità limitata influenzino la dinamica economica. Nel primo capitolo viene presentato un esperimento nel quale ai soggetti viene chiesto di predire il valore futuro dell'inflazione: a seconda del trattamento, i soggetti possono venire esposti ad un segnale, che mira a stabilizzare l'economia, che fungendo quindi da indicazione prospettica (Forward Guidance). I risultati vengono poi studiati sottolineando il meccanismo di formazione delle aspettative soprattutto in funzione della credibilità del segnale; inoltre viene studiata l'efficacia dello strumento di politica monetaria nella stabilizzazione del sistema economico: si evidenzia come un segnale informativo permetta una sensibile stabilizzazione dell'economia, prevenendo spirali deflazionistiche. Nel secondo capitolo viene sviluppato un modello ad agenti il quale incorpora un meccanismo di formazione delle aspettative a razionalità limitata, derivato da esperimenti precedenti. Inoltre, grazie ad un peculiare processo di aggregazione, viene derivato un modello analiticamente trattabile che permette di studiare il meccanismo di trasmissione di uno shock, isolando gli effetti dovuti all'eterogeneità fra gli agenti e alle aspettative: entrambi gli effetti sono considerevoli ed aiutano nello spiegare la dinamica economica. / The present dissertation analyses expectations in macroeconomics, contributing to the existing literature both studying the expectation formation process, and inquiring how economic dynamic is influenced by boundedly rational expectations. The first chapter presents a learn to forecast experiment in which subject are asked to form expectation regarding the future value of inflation: depending on the treatment, subjects might be exposed to a signal, which possibly aim at stabilizing economy, mimicking the non conventional monetary policy instrument called Delphic Forward Guidance. The collected data are studied trying to recover the underlying expectation formation process highlighting especially the role of credibility of the signal; moreover from the data emerges that informative Forward Guidance helps in stabilizing economy, drastically reducing the probability of deflationary spirals. The second chapter develops an agent-based model, encapsulating a boundedly rational expectation formation process, which had been extrapolated in previous experiments. Moreover benefiting from a specific aggregation procedure, we derive a model characterized by high analytical tractability, allowing hence to study the transmission mechanisms of a shock by insulating the effects due to the heterogeneity among agents and due to expectations: both the effects are sizable and help in understanding the dynamics of the economic system.

Volba školy v primárním vzdělávání jako důležitý mechanizmus ovlivňující spravedlivý přístup ke vzdělávání / Primary school choice - an important mechanism influencing equity in education

Simonová, Jaroslava January 2015 (has links)
Primary school choice - an important mechanism influencing equity in education Jaroslava Simonová Abstract This dissertation describes the process of school choice in primary education and the factors influencing it. Using a qualitative grounded theory design, the work builds on data from 41 interviews with parents from diverse socio-economic backgrounds. Parents' decision-making about school choice is shaped primarily by the organizational needs of parents and their inner need to be a "good parent". When being interviewed, parents report a number of criteria, which, according to them, are important in school choice. However, for many of them they fail to obtain relevant and reliable information. Therefore, they may eventually make a decision based on criteria other than those referred to as important, although they are rarely aware of this shift and the change in criteria. There are three unavoidable criteria in decision-making: availability, reputation and the emotions that parents experienced at school during their visit. The child's needs are the important intervening conditions. They play an important role, especially if the parents feel that their child has some particular needs. The parents' experience with the education system and their personality characteristics are also important. The significant...

Personalnyckeltalens betydelse i beslutsprocesser / The significance of key performance indicators in decision making

Gadelius, Moa January 2022 (has links)
Bakgrund och problem  Det har blivit mer vanligt att räkna på de mänskliga resurserna i organisationer, vilket har lett till att HR-avdelningen har fått en mer strategisk roll och tagit avstånd från att bara varit en administrativ stödfunktion. Människor är de som organiserar beslutsfattning och agerar utefter beslutsproblem varav det behövs kompetent personal, regler och struktur. Beslutsprocesserna genomgås ofta med en vision av vad önskat resultat ska bli vilket ofta går i enlighet med organisationens mål. Personalnyckeltal används av alla organisationer i någon mening. Vanligtvis i ett jämförande syfte från tidigare år, till andra konkurrenter eller för att se trender. De bidrar till att föra organisationen framåt mot de uppsatta målen. Det mänskliga kapitalet är svårare att räkna på än andra immateriella tillgångar, men att ändå kunna använda sig av personalnyckeltalen i beslutsprocesser bör därför kunna resultera i en mer tydlig process. Syfte och metod  Syftet med studien var att utöka den teoretiska och praktiska kunskapen om betydelsen personalnyckeltal har i organisationers beslutsprocesser. För att undersöka detta tillämpades därför en kvalitativ metod där fem semistrukturerade intervjuer genomfördes med intervjupersoner från både privat och offentlig sektor.  Resultat och slutsats Studien resulterade i en ökad teoretisk och praktisk kunskap då personalnyckeltal har en betydelse för organisationers beslutsprocesser i de faser där de agerar som underlag. Det är ytterst viktigt att använda sig av siffror som personalnyckeltal när en organisation identifierar ett problem, samlar in information till beslut och sedan utvärderar den process som genomförts och det beslut som implementerats. / Background and problem Accounting for the human resources within organizations have become more common which have led to a more strategic role for the HR-department and a departure from its original role as a supportive administrative part of the organization. Humans are the ones who organize decision making and therefore act along the problems of the decision where competent personnel, rules and structure are needed. The decision-making processes are often undergoing with a vision of what the wanted result is which often is in conjunction with the goal of the organization. All organizations have use of key performance indicators in some capacity. It´s commonly used with a comparative purpose in contrast of previous years, comparing key performance indictors to other competitors or to spot trends. They contribute to bring the organization towards its goals. The human capital is harder to account for than other intangible assets, but to be able to use key performance indicators in decision-making processes should therefore result in a more distinct process.  Purpose and method  The purpose of this study was to expand the theoretical and practical knowledge of the significance that key performance indicators have in organizational decision-making processes. A qualitative method was therefore used where five semi structured interviews were conducted with interviewing persons from both the private and public sector. Results and conclusion  This study resulted in an increased theoretical and practical knowledge in that key performance indicators have a significant matter in organizational decision-making processes in those phases where they act as a groundwork. It is of utmost importance to use digits like key performance indicators when an organization identifies a problem, collects information to be used for the decision and later evaluates the previous process and the decision that has been implemented.

Essays on experimental group dynamics and competition

William J Brown (10996413) 23 July 2021 (has links)
<div>This thesis consists of three chapters. In the first chapter, I investigate the effects of complexity in various voting systems on individual behavior in small group electoral competitions. Using a laboratory experiment, I observe individual behavior within one of three voting systems -- plurality, instant runoff voting (IRV), and score then automatic runoff (STAR). I then estimate subjects' behavior in three different models of bounded rationality. The estimated models are a model of Level-K thinking (Nagel, 1995), the Cognitive Hierarchy (CH) model (Camerer, et al. 2004), and a Quantal Response Equilibrium (QRE) (McKelvey and Palfrey 1995). I consistently find that more complex voting systems induce lower levels of strategic thinking. This implies that policy makers desiring more sincere voting behavior could potentially achieve this through voting systems with more complex strategy sets. Of the tested behavioral models, Level-K consistently fits observed data the best, implying subjects make decisions that combine of steps of thinking with random, utility maximizing, errors.</div><div><br></div><div>In the second chapter, I investigate the relationship between the mechanisms used to select leaders and both measures of group performance and leaders' ethical behavior. Using a laboratory experiment, we measure group performance in a group minimum effort task with a leader selected using one of three mechanisms: random, a competition task, and voting. After the group task, leaders must complete a task that asks them to behave honestly or dishonestly in questions related to the groups performance. We find that leaders have a large impact on group performance when compared to those groups without leaders. Evidence for which selection mechanism performs best in terms of group performance seems mixed. On measures of honesty, the strongest evidence seems to indicate that honesty is most positively impacted through a voting selection mechanism, which differences in ethical behavior between the random and competition selection treatments are negligible.</div><div><br></div><div><br></div><div>In the third chapter, I provide an investigation into the factors and conditions that drive "free riding" behavior in dynamic innovation contests. Starting from a dynamic innovation contest model from Halac, et al. (2017), I construct a two period dynamic innovation contest game. From there, I provide a theoretical background and derivation of mixed strategies that can be interpreted as an agent's degree to which they engage in free riding behavior, namely through allowing their opponent to exert effort in order to uncover information about an uncertain state of the world. I show certain conditions must be fulfilled in order to induce free riding in equilibrium, and also analytically show the impact of changing contest prize structures on the degree of free riding. I end this paper with an experimental design to test these various theoretical conclusions in a laboratory setting while also considering the behavioral observations recorded in studies investigating similar contest models and provide a plan to analyze the data collected by this laboratory experiment.</div><div><br></div><div>All data collected for this study consists of individual human subject data collected from laboratory experiments. Project procedures have been conducted in accordance with Purdue's internal review board approval and known consent from all participants was obtained.</div>

Känslighetsanalys och begränsad rationalitet : Hur använder företag känslighetsanalyser i beslutsprocessen vid investeringar? / Sensitivity analysis and bounded rationality : How do companies use sensitivity analysis in the decision-making process when investing?

Gustafson, Viktor, Hedén, Peter January 2020 (has links)
Alla företag har – från tid till annan – någon form av investeringar i sin verksamhet. För att utvärdera olika investeringsalternativ används investeringskalkyleringar, men de bakomlig-gande antaganden som görs vid dessa kalkyler är präglade av osäkerhet då ingen kan sia om framtidens utfall. Ett verktyg som kan användas för att hantera denna osäkerhet är känslighets-analys. Det finns många studier gjorda om känslighetsanalyser, men nästan alla följer en rationell an-sats och tar sällan hänsyn till den begränsade rationella människan som står bakom analyserna. Syftet med denna studie är att analysera hur företag använder sig av känslighetsanalys i sam-band med investeringsbeslut, oavsett om de förhåller sig till den rationella ansatsen eller inte. Studien har därför genomförts med intervjuer för att kunna uppnå detta syfte. Studien visar på att det finns viktiga faktorer som gör att känslighetsanalysens roll och använ-dande inför investeringsbeslut skiljer sig åt i de intervjuer vi gjort. Faktorerna som denna studie har tagit hänsyn till är hur ägarstrukturen ser ut, vilka typer av investeringar som görs och organisationens tolkningsprocess av omgivningen. Genom vår analysmodell hoppas vi kunna visa på varför behovet och utförandet av känslighetsanalysen ser ut som det gör, men även ge en förståelse för varför den skiljer sig åt mellan olika företag. / All companies have some form of investment in their business. To evaluate different invest-ment options, they will use some form of capital budgeting techniques. However, the underly-ing assumptions made in these calculations are characterized by uncertainty, as no one can predict the outcome of the future. One tool that can be used to deal with this uncertainty is sensitivity analysis. There have been many studies done on the subject of sensitivity analysis. But almost all of them follow a rational approach and rarely consider the limited rational person behind these analyses. The purpose of this study is to analyse how companies use sensitivity analysis for investment decisions, regardless of whether they relate to the rational approach or not. This study was therefore conducted with interviews to be able to achieve this purpose. This study shows that there are important factors that change the sensitivity analysis purpose and how it is used for investments decisions in the interviews that we have done. The factors this study will take into account are company structures, types of investments and how organ-izations manage their interpretation process of their environment. Through our analysis model we hope to show why the need and implementation of sensitivity analysis looks the way it does and provide an understanding of why it differs between companies.

Resource-Bounded Reasoning about Knowledge

Ho, Ngoc Duc 28 November 2004 (has links)
Der Begriff ``Agent'''' hat sich als eine sehr nützliche Abstraktion erwiesen, um verschiedene Problembereiche auf eine intuitive und natürliche Art und Weise zu konzeptualisieren. Intelligente Agenten haben daher Anwendung gefunden in verschiedenen Teilbereichen der Informatik. Zur Modellierung werden intelligente Agenten meist als intentionale Systeme aufgefaßt und mit Hilfe von mentalistischen Begriffen wie Wissen, Glauben (oder Überzeugung), Wunsch, Pflicht, Intention usw. beschrieben. Unter diesen mentalen Begriffen gehören die epistemischen Begriffe (d.h., Wissen und Glauben) zu den wichtigsten und wurden auch am intensivsten untersucht. Zur Modellierung von Wissen und Glauben werden in der Regel modale epistemische Logiken verwendet. Solche Systeme sind aber nicht geeignet, um ressourcenbeschränkte Agenten zu beschreiben, weil sie zu starke Annahmen bezüglich der Rationalität von Agenten machen. Zum Beispiel wird angenommen, daß Agenten alle logischen Wahrheiten sowie alle Konsequenzen seines Wissens kennen. Dieses Problem ist bekannt als das Problem der logischen Allwissenheit (``logical omniscience problem''''). Da alle Agenten grundsätzlich nur über begrenzte Ressourcen (wie z.B. Zeit, Information, Speicherplatz) verfügen, können sie nur eine begrenzte Menge von Informationen verarbeiten. Daher müssen alternative Modelle entwickelt werden, um Agenten realistisch modellieren zu können (siehe Kapitel 2). Daß modale epistemische Logik für die Formalisierung des ressourcenbeschränkten Schließens (``resource-bounded reasoning'''') nicht geeignet ist, wird als ein offenes Problem der Agententheorien anerkannt. Es gibt bisher aber keine brauchbaren Alternativen zur Modallogik. Die meisten Ansätze zur Lösung des logischen Allwissenheitsproblems versuchen, Wissen und Glauben mit Hilfe schwacher Modallogiken zu beschreiben. Solche Versuche sind nicht befriedigend, da sie eine willkürliche Einschränkung der Rationalität der Agenten zur Folge haben (siehe Kapitel 3). Mein Ziel ist es, einen Rahmen für das ressourcenbeschränktes Schließen über Wissen und Glauben zu entwickeln. Damit soll eine solide Grundlage für Theorien intelligenter Agenten geschaffen werden. Als Nebenergebnis wird das logische Allwissenheitsproblem auf eine sehr intuitive Art und Weise gelöst: obwohl Agenten rational sind und alle logischen Schlußregeln anwenden können, sind sie nicht logisch allwissend, weil ihnen nicht genügend Ressourcen zu Verfügung stehen, um alle logischen Konsequenzen ihres Wissens zu ziehen. Im Kapitel 4 wird eine Reihe von Logiken vorgestellt, die den Begriff des expliziten Wissens formalisieren. Es wird eine Lösung des Problems der logischen Allwissenheit der epistemischen Logik vorgeschlagen, die die Rationalität der Agenten nicht willkürlich einschränkt. Der Grundgedanke dabei ist der folgende. Ein Agent kennt die logischen Konsequenzen seines Wissens nur dann, wenn er sie tatsächlich hergeleitet hat. Wenn ein Agent alle Prämissen einer gültigen Schlußregel kennt, kennt er nicht notwendigerweise die Konklusion: er kennt sie nur nach der Anwendung der Regel. Wenn er den Schluß nicht ziehen kann, z.B. weil er nicht die notwendigen Ressourcen dazu hat, wird sein Wissen nicht um diese herleitbare Information erweitert. Die Herleitung neuer Informationen wird als die Ausführung mentaler Handlungen aufgefaßt. Mit Hilfe einer Variante der dynamischen Logik können diese Handlungen beschrieben werden. Im Kapitel 5 werden Systeme für das ressourcenbeschränkte Schließen über Wissen und Glauben entwickelt, die auch quantitative Bedingungen über die Verfügbarkeit von Ressourcen modellieren können. Mit Hilfe dieser Logiken können Situationen beschrieben werden, wo Agenten innerhalb einer bestimmten Zeitspanne entscheiden müssen, welche Handlungen sie ausführen sollen. Der Ansatz besteht darin, epistemische Logik mit Komplexitätstheorie zu verbinden. Mit Hilfe einer Komplexitätsanalyse kann ein Agent feststellen, ob ein bestimmtes Problem innerhalb vorgegebener Zeit lösbar ist. Auf der Grundlage dieses Wissens kann er dann die für die Situation geeignete Entscheidung treffen. Damit ist es gelungen, eine direkte Verbindung zwischen dem Wissen eines Agenten und der Verfügbarkeit seiner Ressourcen herzustellen. / One of the principal goals of agent theories is to describe realistic, implementable agents, that is, those which have actually been constructed or are at least in principle implementable. That goal cannot be reached if the inherent resource-boundedness of agents is not treated correctly. Since the modal approach to epistemic logic is not suited to formalize resource-bounded reasoning, the issue of resource-boundedness remains one of the main foundational problems of any agent theory that is developed on the basis of modal epistemic logic. My work is an attempt to provide theories of agency with a more adequate epistemic foundation. It aims at developing theories of mental concepts that make much more realistic assumptions about agents than other theories. The guiding principle of my theory is that the capacities attributed to agents must be empirically verifiable, that is, it must be possible to construct artificial agents which satisfy the specifications determined by the theory. As a consequence, the unrealistic assumption that agents have unlimited reasoning capacities must be rejected. To achieve the goal of describing resource-bounded agents accurately, the cost of reasoning must be taken seriously. In the thesis I have developed a framework for modeling the relationship between knowledge, reasoning, and the availability of resources. I have argued that the correct form of an axiom for epistemic logic should be: if an agent knows all premises of a valid inference rule and if he performs the right reasoning, then he will know the conclusion as well. Because reasoning requires resources, it cannot be safely assumed that the agent can compute his knowledge if he does not have enough resources to perform the required reasoning. I have demonstrated that on the basis of that idea, the problems of traditional approaches can be avoided and rich epistemic logics can be developed which can account adequately for our intuitions about knowledge.

Sprida, Styra, Främja : Identifiering och analys av potentiella komplikationer för nedbrytning av social tillit i det svenska samhället / Disseminate, Steer, Promote : Identification and analysis of potential complications for the decomposition of social trust in the Swedish society

Holmberg, Elsa, Lehrman, Cecilia January 2023 (has links)
Social tillit är en central faktor i ett välfungerande samhälle och skapar förutsättningar för ekonomisktillväxt och sänkta transaktionskostnader. Att förstå vilka komponenter som kan bidra till nedbrytning avsocial tillit har därför stor betydelse för att kunna påverka samhällsutvecklingen. Syftet med denna uppsats är att identifiera och analysera drivkrafter och mekanismer som kan bryta ned social tillit i Sverige. En del forskare, däribland Robert Putnam, pekar på att etnisk mångfald på kort sikt kan bryta ned tillit. För att besvara uppsatsens syfte består studien av tre steg. Först identifieras tre komplikationer samt teser som utgör grunden för vår analysmodell. Dessa är modern informationsteknologi kan sprida misstro, identitet och polariserande drivkrafter kan styra individer att inte lita på andra samt begränsad rationalitet kan främja nedbrytningen av social tillit. Därefter genomfördes en omfattande litteraturstudie. Arbetet avslutades med en kvalitativ studie med sju semistrukturerade intervjuer där forskare och professorer fick granska den analysmodell som identifierats i studiens första steg. Komplikationerna analyseras med utgångspunkt i spelteorins förtroendespel. Även ett köns- ochgenusperspektiv inkluderas i analysen för att ta hänsyn till jämställdhetens centrala roll för ett fungerande högtillitssamhälle. Uppsatsen är explorativ och undersöker komplikationer som inte tidigare forskats kring. Därför önskade vi få kunskapsbidrag från professorer och forskare från olika discipliner för att skapa en helhetsbild av komplikationernas relevans för nedbrytningen av social tillit. Studien pekar på ett fortsatt högt och stabilt tillitsläge i Sverige och utöver komplikationerna visar studien att ekonomisk ojämlikhet och brist på gemenskap kan bidra till nerbrytning av social tillit. Denna hypotesgenererande uppsats ger upphov till tre hypoteser för fortsatt forskning. Att identitet och polariserande drivkrafter direkt kan förklara nedbrytning av social tillit genom att styra individer att inte lita på andra. Att modern informationsteknologi och begränsad rationalitet indirekt kan förklara nedbrytning av social tillit genom att sprida misstro respektive främja nedbrytningen. Att Putnams tes endast ger en förenklad bild av verkligheten och att etnisk mångfald inte ärdet största hotet för nedbrytning av social tillit. / Social trust is a key factor in a prosperous society and creates prerequisites for economic growth and reduced transaction costs. It is of significant value to understand which components contribute to the decomposition of social trust in order to impact social development. The purpose of this essay is toidentify and analyze forces and mechanisms that could decompose social trust in Sweden. Some researchers, including Robert Putnam, indicate that ethnic diversity could decompose trust in the short run. To answer the purpose of this study, the study consists of three stages. Three complications as well as theses were first chosen to create our analytical model. These are, that modern information technology could disseminate mistrust, that identity and polarizing forces could steer individuals not to trust others and that bounded rationality could promote the decomposition of social trust. After this stage, an extensive literature study was conducted. Lastly, a qualitative study with seven semi-structured interviews took place where professors and researchers were asked to review the analytical model that was conducted in the first stage of the study. The complications are analyzed from a game theoretic- and gender perspective. The study is explorative and examines complications that have not previously been examined or researched. As of this, we wish to gather knowledge from professors and researchers from different disciplines to create a holistic view of the complication's relevance on the decomposition of social trust. The study indicates a continuously high and stable state of trust in Sweden and, beyond the complications, the study shows that economic inequality and lack of community can contribute to the decomposition of social trust. This hypothesis generating essay originates three hypotheses for further research. That identity and polarizing forces could directly explain the decomposition of social trust by disseminating individuals not to trust others. That modern information technology and bounded rationality could indirectly explain the decomposition of social trust by steering mistrust respectively promoting the decomposition. That Putnam ́s thesis gives a simplified view of reality, and that ethnic diversity is not themost significant threat for the decomposition of social trust.

Evolutionary Behavioral Economics: Essays on Adaptive Rationality in Complex Environments

Benincasa, Stefano 25 June 2020 (has links)
Against the theoretical background of evolutionary behavioral economics, this project analyzes bounded rationality and adaptive behaviour in organizational settings characterized by complexity and persistent uncertainty. In particular, drawing upon the standard NK model, two laboratory experiments investigate individual and collective decision-making in combinatorial problems of resource allocation featuring multiple dimensions and various levels of complexity. In the first study, investment horizons of different length are employed to induce a near or distant future temporal orientation, in order to assess the effects of complexity and time horizon on performance and search behaviour, examine the presence of a temporal midpoint heuristic, and inspect the moderating effects of deadline proximity on the performance-risk relationship. This is relevant for organizational science because the passage of time is essential to articulate many strategic practices, such as assessing progress, scheduling and coordinating task-related activities, discerning the processual dynamics of how these activities emerge, develop, and terminate, or interpreting retrospected, current, and anticipated events. A greater or lesser amount of time reflects then a greater or lesser provision of resources, thereby representing a constraint that can greatly affect the ability to maintain a competitive advantage or ensure organizational survival. In the second study, the accuracy of the imitative process is varied to induce a flawless or flawed information diffusion system and, congruently, an efficient or inefficient communication network, in order to assess the effects of complexity and parallel problem-solving on autonomous search behaviour, clarify the core drivers of imitative behaviour, control for the degree of strategic diversity under different communication networks, and evaluate individual as well as collective performance conditional to the interaction between the levels of complexity and the modalities of parallel problem-solving. This is relevant for organizational science because imitating the practices of high-performing actors is one of the key strategies employed by organizations to solve complex problems and improve their performance, thereby representing a major part of the competitive process. The project is intended to contribute grounding individual and collective behaviour in a more psychologically and socially informed decision-making, with a view to further the research agenda of behavioral strategy and sustain the paradigm shift towards an evolutionary-complexity approach to real economic structures.

Projets des logements à la suite des désastres : analyse du système organisationnel et évaluation de la satisfaction des usagers dans un projet de reconstruction dans la région du Maghreb

Bouraoui, Dhouha 01 1900 (has links)
Plusieurs études ont révélé des problèmes récurrents au niveau de la performance et de la gestion des projets de reconstruction à la suite des catastrophes dans les pays en voie de développement (PEVD). Ces projets doivent faire face à des conditions de vulnérabilité des habitants, engendrées par des facteurs politiques, économiques, sociaux et culturels. Les divers participants - contraints par un accès limité à l’information - sont confrontés à travailler dans un contexte hostile ayant un niveau d’incertitude élevé. Ce niveau d’incertitude augmente les risques du projet de reconstruction, particulièrement le risque d’insatisfaction des usagers. Ce travail vise à mettre en parallèle l’analyse du système organisationnel adopté pour la conduite d’un projet de reconstruction et celle du niveau de satisfaction des usagers. Il émet l’hypothèse suivante: deux facteurs organisationnels influencent largement le niveau de satisfaction de la part des bénéficiaires d’un projet de reconstruction de logements à la suite d’un désastre en PEVD: (i) le niveau de centralisation de la prise de décisions (jumelée au manque d’information) au sein de la Multi-Organisation Temporaire (MOT); et (ii) la capacité de la structure organisationnelle de la MOT d’impliquer la participation active des usagers au niveau de la planification, de la gestion, du financement et du design du projet. Afin d’atteindre cet objectif, une recherche empirique fut menée pour analyser le cas des inondations ayant eu lieu en 2003 dans une ville dans la région du Maghreb. Le niveau de satisfaction des usagers a été déterminé grâce à des indicateurs de transfert de technologie qui se basent sur l’analyse du « Cadre Logique » - une méthode d’évaluation largement utilisée dans le domaine du développement international. Les résultats de la recherche ne visent pas à identifier une relation de cause à effet entre les deux variables étudiées (la structure organisationnelle et la satisfaction des usagers). Cependant, ils mettent en évidence certains principes du montage et de la gestion des projets qui peuvent être mis en place pour l’amélioration des pratiques de reconstruction. / Construction projects are temporary endeavors with a defined beginning and end, conducted by a temporary and multi-disciplinary team called a Temporary Multi-Organization (TMO). In the hostile environment of post-disaster reconstruction, participants of the TMO must confront high levels of uncertainty which increases project risks. The non-acceptability of project outcomes is one of the most frequent risks reported in literature (UNDRO, 1982; Barenstein, 2008; Dikmen, 2006). Acceptability is related with users’ satisfaction. However, according to the theory of bounded rationality, actors of the TMO - confronted with limited information and resources - cannot achieve an optimal solution. Instead, both project actors and end-users accept a «satisficing» [SIC] solution (Simon, 2004). This study hypothesizes that two organizational factors have an important influence on user satisfaction in post-disaster housing projects: (i) centralized decision making (coupled with lack of information); and (ii) the capacity of the structure of the Temporary Multi-Organization (TMO) to take into account the active participation of users in project planning, management, financing and design. A case study of a post-disaster housing project in the Maghreb region helps us validate this hypothesis. Building up on this hypothesis, indicators of technology transfer (as proposed by the Logical Framework Analysis) serve as a basis to assess users’ satisfaction. The research does not establish a cause-effect relationship between the two variables of the study. However, the analysis of the structure of the TMO and users’ satisfaction highlight several principles, related with the project initiation and management, that can be implemented to improve reconstruction practices in developing countries.
