Dopo l’analisi delle modalità di misurazione del potere di mercato e della competizione tra brand nel contesto di un mercato caratterizzato dalla presenza di prodotti differenziati, viene presentata l’applicazione dei modelli a scelta discreta nel mercato del latte alimentare in Italia. Ho utilizzato dati scanner per analizzare i comportamenti nelle scelte di acquisto dei consumatori e le dinamiche competitive tra i due maggiori brand presenti nel mercato e le marche commerciali. Ho considerato il mercato del latte alimentare suddiviso in due sottocategorie, quella del latte a lunga conservazione (UHT) e quella del latte refrigerato. Ho quindi proceduto alla stima della domanda del latte alimentare utilizzando un nested logit model, appartenente alla categoria dei modelli a scelta discreta. Utilizzando i coefficienti stimati è possibile sia calcolare le elasticità di sostituzione tra i diversi brand e le elasticità dirette, nonché i margini di profitto dei brand presi in analisi considerando differenze nelle strategie di prezzo e nella struttura di mercato. / This work first gives an overview of the measurement of market power and brand competition in a differentiated products market, secondly applies discrete choice models to asses the Italian milk market. I use scanner data to estimate consumer purchasing decisions and competitive relationships between two major industry-level brands and (as a third category) supermarket private labels. I divide all milk sold in Italian market into two distinct classes of products: “UHT” and “Refrigerated” milk. I employ a well-known “discrete choice” nested-logit model to estimate consumer demand. Then, using the estimated coefficients, it is possible to calculate both consumer substitution patterns between products, and the profit-margins of the three major retail-level brands across the different sub-categories of milk under different pricing strategies and market structure.

This D.Phil. thesis develops a new agent-based simulation model to improve the results of analysis, which solely uses discrete choice modelling, as well as to analyse the effects of a road user charging scheme for the Upper Derwent Valley in the Peak District National Park. The advantages of discrete choice analysis are well known. However, results with these conventional conventional approaches, which conduct analysis solely with discrete choice models, can be biased if interaction and learning effects are significant. The Minority Game, in which agents try to choose the option of the minority side, is an appropriate tool to deal with these problems. The situation in the Upper Derwent Valley can be explained with economic game theories and the Minority Game. The two approaches mutually help to analyse the situation in the Upper Derwent Valley leading to the development of a stochastic Minority Game. The stochastic Minority Game was tested with an online game (questionnaire), which was played 3,886 times by response in all around the world. The practical part of this thesis examines the components of the stochastic Minority Game with the data collected around the Upper Derwent Valley. The main data was collected using a stated preference survey. Overall, 700 questionnaires were distributed and 323 of them were returned (i.e. a return rate of 46.1 %). In the practical part, the agent-based model has four sub modules: 1) Multinomial mixed logit model for mode choice, 2) Binary logit model for parking location choice, 3) Markov queue model for parking network, and 4) the Minority Game for parking congestion and learning. This simulation model produces comprehensive outputs including mode choices, congestion levels, and user utilities. The results show that the road user charging scheme reduces car demand in the Upper Derwent Valley and ensures a reduction in congestion at the parking areas. The model also shows that an exemption will increase the utilities of elderly visitors without substantially sacrificing those of younger visitors. In conclusion, the simulation model demonstrated that oversimplification in conventional approaches solely using discrete choice models gave significant biases when real world problems were analysed.

Στην παρούσα διπλωματική εργασία διερευνήθηκε η επιλογή των πρωτοετών φοιτητών αναφορικά με το τμήμα της πανεπιστημιακής τους εκπαίδευσης στην Ελλάδα. Ειδικότερα, αυτή η επιλογή αξιολογείται μέσω δυο μεταβλητών. Η πρώτη αφορά το αντικείμενο σπουδών με βάση το επιστημονικό περιεχόμενο του προγράμματος σπουδών και η δεύτερη αφορά τις προεξοφλημένες αποδόσεις ανά αντικείμενο σπουδών. Για λόγους εκτίμησης χρησιμοποιήθηκαν δεδομένα για το έτος 2006 από το Ατομικό Δελτίο Φοιτητή-Σπουδαστή της Ελληνικής Στατιστικής Αρχής (Ελ.ΣΤΑΤ) και εφαρμόστηκαν υποδείγματα διακριτής επιλογής με διάταξη (ordered probit) αλλά και χωρίς διάταξη (binary probit). Ως επεξηγηματικές μεταβλητές χρησιμοποιήθηκαν το επίπεδο εκπαίδευσης, το επάγγελμα των γονέων και μια ευρεία δέσμη δημογραφικών μεταβλητών (ηλικία, φύλο, τόπος γέννησης, κ.λπ.). Όπως προέκυψε από τα αποτελέσματα της οικονομετρικής ανάλυσης η επιλογή του πανεπιστημιακού τμήματος (είτε με βάση το αντικείμενο σπουδών είτε με βάση τις προεξοφλημένες αποδόσεις) επηρεάζεται σημαντικά από το οικογενειακό υπόβαθρο (εκπαίδευση, επάγγελμα) του πρωτοετή φοιτητή. Επίσης, διερευνήθηκε η σχέση μεταξύ του οικογενειακού εισοδήματος και της επιλογής πανεπιστημιακού τμήματος με βάση τις μελλοντικές αποδόσεις και βρέθηκε να υπάρχει μια θετική και στατιστικά σημαντική σχέση μεταξύ αυτών των δυο μεταβλητών. Με βάση τα αποτελέσματα της παρούσας εργασίας, η δια-γενεακή κινητικότητα στην Ελλάδα (που σχετίζεται με την επιλογή του πανεπιστημιακού τμήματος από τους πρωτοετείς φοιτητές) αναμένεται να είναι χαμηλή. / In this thesis is investigated the choice of the university major of study of the Greek freshmen. Specifically, this choice of major is assessed through two variables. The first is the object of study based on the scientific content of the curriculum and the second is the discounted returns of education per major of study. For assessment purposes we used data for the year 2006 from the Greek statistic authority (el.stat)and we applied discrete choice models by order (ordered probit) and also without order (binary probit). As explanatory variables are used the educational attainment and occupation of parents as well as a wide range of demographic variables (age,sex,place of birth, etc). As the results of the econometric analysis demonstrate the choice of university department(regardless the type of the discrete choice model we use) is significantly influenced by the family background and their social class. It is also investigated the relationship between family income and choice of university department based on future earnings and is found to be a positive and statistically significant relationship between these two variables. Based on the results of this study the intergenerational mobility in Greece (associated with the major of study the freshmen choose) is expected to be low.

Les régions urbaines alpines et en proximité des Alpes présentent des caractéristiques spécifiques: elles combinent une ressource foncière limitée pour l'urbanisation et une qualité environnementale particulière dans l'arrière-pays. Cette combinaison les rend particulièrement propices à la péri-urbanisation, et potentiellement à la ségrégation sociale. Dans le contexte d'une métropolisation croissante, ces deux processus entravent des objectifs centraux de la planification urbaine, à savoir la compacité des formes urbaines, la mixité fonctionnelle, l'égalité territoriale et la cohésion sociale. Dans les régions urbaines alpines, les liens entre l'environnement montagnard, les politiques de planification et les processus résidentiels à l’œuvre restent toutefois peu connus.Cette thèse analyse la planification urbaine et des choix de localisation résidentielle en région urbaine alpine. Elle cherche à comprendre les liens entre l'environnement montagnard, les politiques de planification urbaine et deux processus résidentiels: la péri-urbanisation et la ségrégation sociale. Son objectif général est de mettre en lumière comment et dans quelle mesure ces processus résidentiels sont influencés par (i) l'environnement montagnard et (ii) les politiques de planification pour ainsi fournir des recommandations pour la planification territoriale en région urbaine. Pour cela, nous nous appuyons sur trois contributions distinctes en utilisant la région urbaine de Grenoble comme zone d'étude centrale.La première contribution porte sur les changements dans la pratique de la planification urbaine contemporaine dans la région d'étude. Basée sur une recherche qualitative, elle se concentre sur l'émergence d'une planification territoriale stratégique et sa montée en échelle vers des périmètres de planification plus larges intégrants les espaces péri-urbains. Le chapitre montre la création de nouvelles arènes de gouvernance qui remettent en question les cultures de planification locale.La deuxième contribution analyse les liens entre les préférences pour l'environnement naturel, les choix de localisation résidentielle et la ségrégation sociale. En utilisant des modèles de choix de localisation pour la région d'étude et la région métropolitaine de Marseille, cette partie présente une analyse de ségrégation contrefactuelle qui compare les résultats de ségrégation og avec fg{} et og sans fg{} les préférences pour l'environnement naturel entre les deux régions. Le principal résultat est que la recherche des milieux naturels par les ménages a des effets significatifs sur la ségrégation sociale. Cette recherche a le plus souvent tendance à renforcer la ségrégation, mais peut également être un facteur d'atténuation.La dernière contribution étudie les liens entre les politiques de planification urbaine et les processus résidentiels. Le chapitre développe un modèle de choix discrets pour créer et analyser des simulations de demande résidentielle pour différents scénarios de politique de planification. Les résultats illustrent que les scénarios tendanciels de planification soutiennent et potentiellement renforcent la périurbanisation dans la région d'étude. Des politiques de planification plus contraignantes semblent capables de freiner et potentiellement d'inverser la dispersion de la demande. Les politiques visant à ré-centraliser la demande tendent à maintenir, voire accroître les niveaux de ségrégation sociale.Les résultats de cette thèse suggèrent l'importance d'une prise en compte plus grande de l'environnement naturel dans la planification urbaine et territoriale. Si les disparités spatiales dans la qualité environnementale contribuent aux processus résidentiels qui portent atteintes aux objectifs du développement urbain, les politiques de planification devraient rendre compte de ces disparités afin de limiter l'étalement urbain, la ségrégation sociale et l'inégalité environnementale, non seulement dans un contexte de région urbaine alpine. / Urban regions in and close to the Alps have specific characteristics: they combine a limited land resource for urban development with particular environmental quality in their mountainous hinterland. This combination makes them particularly prone to peri-urbanisation, and potentially social segregation. In the context of continued metropolisation, both of these processes work against central objectives of urban planning, notably compactness of settlement patterns, functional mix, social equity and cohesion. In Alpine urban regions, the links between the mountain environment, urban planning policies and residential processes remain, however, not well understood.This thesis analyses urban planning and residential moves in an Alpine urban region. It seeks to understand the links between the mountain environment, urban planning and notably two residential processes: peri-urbanisation and social segregation. Its general objective is to investigate how and to what extent these residential processes are influenced by (i) the mountain environment and (ii) urban planning policies and to develop recommendations for urban and regional planning. The thesis does this via three distinct contributions which use the urban region of Grenoble in the French Alps as a central study area.The first contribution addresses changes in contemporary urban planning practice in the study region. Based on qualitative research, it focuses on the shift towards strategic spatial planning and on territorial re-scaling towards large urban-peri-urban planning perimeters. The chapter shows the creation of new governance arenas which call into question local planning cultures.The second contribution investigates the links between preferences for the natural environment, residential moves and social segregation. Using location choice models for the study region and the Marseille metropolitan area, this chapter presents a counterfactual segregation analysis that compares segregation outcomes ``with'' and ``without'' preferences for the natural environment. The main result is that households' search for natural environments has significant impacts on social segregation. It most often contributes to reinforcing segregation, but can also be an attenuating factor.The last contribution investigates the links between urban planning policies and residential processes. The chapter develops a residential location choice model in order to predict and analyse residential demand patterns for different planning policy scenarios in terms of concentration and segregation. The scenario results show that continued trends in urban planning policies would sustain and potentially reinforce peri-urbanisation in the region. Confining planning policies are found to be capable of curbing and potentially reversing demand dispersion. Policies that aim at re-centralising demand sustain and potentially increase social segregation levels.The results of this thesis call for a stronger integration of the natural environment in urban and regional planning. If spatial disparities in environmental qualities contribute to residential processes that are detrimental to compact urban forms and an equitable access to environmental quality, then planning should incorporate and account for these disparities in order to prevent further loss of land resources, socio-spatial fragmentation and environmental inequality, not only in an Alpine urban region context.

This work seeks to understand which factors influence physicians’ choice of practice location right after completing residency. Differently from previous papers, we analyse the Brazilian missalocation and assess the particularities of developing countries. We use a discrete choice model approach with a multinomial logit specification. Two rich databases are employed containing the location and wage of formally employed physicians as well as details from their post-graduation. Our main findings are that amenities matter, physicians have a strong tendency to remain in the region they completed residency and salaries are significant in the choice of urban, but not rural, communities. We conjecture this is due to attachments built during training and infrastructure concerns.

I use the positive correlation test, proposed by Chiappori and Salanié (2000), to assess the existence of asymmetric information in this market. I estimate the effect of health plan on treatment usage, controlling for many variables (measured blood pressure, age, smoker, etc.), identifying the effect of the plan. I use this coefficients as plan characteristics and estimate their effects on plan purchase using a simple logit regression. The coefficients from this estimation show the relative importance of anticipated moral hazard of different treatments on health plan choice. I find evidence of asymmetric information in the market for every state, in either the Metropolitan Area or not, and for the country as a whole. When performing the positive correlation test using hospitalizations as the usage variable, where moral hazard is assumed to be controlled, I find this evidence only for young women and for the last age group (59 years or more). I find no evidence of asymmetric information for plans paid through work, as expected. Several treatments are used more by people with plans, even when controlling for adverse selection. The analysis suggests that some of those are relevant for plan purchase.

Cette thèse se concentre sur l'interdépendance entre les choix de localisation résidentielle et professionnelle. Des questions telles que le processus de prise de décision, l'accessibilité à l'emploi, la répartition géographique des emplois, et le prise de décision collective des conjoints, entre autres, sont analysées en développant des modèles de choix discrets. Dans ce cadre, nous étudions les choix de localisation à partir de deux points de vues complémentaires. (1) Premièrement, nous étudions l'interdépendance entre les deux choix de localisation sans considérer le processus de décision au sein des ménages. Nous développons un modèle logit emboîté à trois niveaux, pour les choix de localisation résidentielle et professionnelle et nous étudions l'effet des mesures d'attractivité et d'accessibilité spécifiques à chaque individu (log-sommes). Les résultats du premier chapitre montrent que l'accessibilité spécifique à chaque individu est un facteur déterminant du choix de localisation résidentielle et que son effet diffère le long du cycle de vie des ménages. L'attractivité des types d'emploi est un meilleur indicateur du choix de localisation professionnelle que le nombre d'emplois. L'évolution des mesures d'attractivité et d'accessibilité aux emplois est analysée dans le deuxième chapitre. (2) Deuxièmement, nous étudions l'interdépendance de la localisation résidentielle et professionnelle au sein du ménage. Cette thèse contribue à la littérature des modèles collectifs en développant un modèle de choix avec processus de négociation au sein des ménages à la Chiappori, pour décrire le choix de localisation résidentielle des ménages bi-actifs. Le dernier chapitre développe et estime un modèle structurel en deux étapes pour faire la part des choses entre le pouvoir de négociation et les valeurs du temps des conjoints. Les résultats montrent que les nationalités du couple, leur niveau d'éducation, ainsi que la différence d'âge entre les conjoints jouent un rôle crucial dans la détermination de pouvoir de négociation. / This thesis studies the interdependency between the choices of residential and workplace location. Issues such as the decision-making process, the accessibility to jobs, the geographical distribution of job types, and the spouses collective decision process, among others, are analyzed with discrete choice models. In this setting, we study the location decisions from two complementary points of view. (1) First, we study the interdependency between the two location choices without any within-household consideration. We develop a three-level nested logit model of residential and workplace location and study the effect of individual-specific attractiveness and accessibility (log-sum) measures. Results presented in the first chapter show that the individual-specific accessibility measure is an important determinant of the choice of residential location and its effect differs along the household life cycle. Additionally, the attractiveness of the types of employment is a better predictor of the workplace location than the usual total number of jobs. We analyze the evolution of the attractiveness and attractivity measures in the second chapter. (2) Second, we study the interdependency of residential location and workplaces within the household. This thesis contributes with a within-household bargaining process model of location decisions. As such, it applies the collectiveapproach à la Chiappori of household behavior to describe residential location choice of two-worker households. The last chapter develops and estimates a two-step structural model to disentangle bargaining powers from spouses' values of time. Results show that the nationalities of the couple, their education level, as well as the age difference between spouses play a crucial role in determining bargaining power.

Em junho de 2013, o reajuste de R$ 0,20 na tarifa de ônibus gerou uma série de manifestações populares no país que acabaram fazendo alguns governos, como o da cidade de São Paulo, voltarem atrás e arcarem com essa diferença com as empresas de ônibus. Visto isso, o prefeito de São Paulo, Fernando Haddad, propôs uma política de municipalização de um tributo imposto sobre a gasolina, a CIDE, para financiar o transporte público urbano. Nesse contexto, foi encomendada uma pesquisa a Fundação Getúlio Vargas para responder a magnitude do impacto desse subsídio cruzado entre usuários do transporte privado e coletivo. Esse trabalho utiliza o resultado encontrado por essa pesquisa para responder qual o efeito sobre o tráfego da Região Metropolitana de São Paulo utilizando dados da Pesquisa de Origem e Destino de 2007. Os resultados encontrados mostram que a política de subsídio cruzado proporciona um baixo deslocamento no fluxo dos modos de transporte. Além disso, a análise de bem estar da política mostra que os mais favorecidos são os indivíduos de baixa renda. A estimação é feita com base em dois modelos de escolha discreta (Multinomial e Mixed Logit), separada por dois motivos de viagem: trabalho e estudo. E, as simulações de deslocamento de demanda utilizam dois valores de tributos, R$ 0,10 e R$ 0,50. / In June 2013, the increase of 0.20 BRL in bus fare has emerged a series of popular demonstrations in the country that ended up making some governments, such as the city of São Paulo, backtrack and pay out this difference with the buses company. So, the mayor of São Paulo, Fernando Haddad, proposed a policy of decentralization of a tax imposed on gasoline, CIDE, to finance urban public transport. In this context, a report was commissioned to Fundação Getúlio Vargas to respond the magnitude of the impact of cross-subsidy between users of private and collective transport. This work uses the results found in this report to answer the effect on traffic in the Metropolitan Region of São Paulo using data from the Source and Destination Survey of 2007. Results show that the cross-subsidy policy provides a low offset in the flow modes of transport. Moreover, the analysis of welfare policy shows that the most favored are the low-income individuals. The estimation is based on two discrete choice models (Multinomial and Mixed Logit), separate for two reasons of trips: work and study. And the simulations of displacement demand use two values of taxes, 0.10 and 0.50 BRL.

nÃo hà / O objetivo deste trabalho à estimar a probabilidade de um trabalhador estar empregado no setor informal, condicionadas as suas caracterÃsticas produtivas, considerando a possibilidade de viÃs de seleÃÃo amostral. A amostra se restringe ao CearÃ, e utiliza a Pesquisa Nacional de Amostras por DomicÃlio (PNAD) 2008 para classificar os trabalhadores em formais e informais. De acordo com a hipÃtese da dualidade, os postos de trabalho no setor formal sÃo efetivamente melhores em vÃrias dimensÃes, e a existÃncia de informalidade ocorre porque o nÃmero destes postos à limitado. Se de fato hà segmentaÃÃo no mercado de trabalho e racionamento dos postos de trabalho formais, à importante saber como ocorre à alocaÃÃo de trabalhadores entre os dois setores. Para tanto, à considerada a possibilidade de viÃs de seleÃÃo na escolha entre os setores formal e informal. O viÃs de seleÃÃo ocorre quando uma sÃrie de caracterÃsticas nÃo observÃveis dos indivÃduos pode fazer com que eles acabem trabalhando, por opÃÃo ou necessidade, no setor informal da economia. Ou seja, caracterÃsticas nÃo observÃveis dos indivÃduos, como habilidade, forÃa de vontade, determinaÃÃo, criatividade etc., podem estar determinando a escolha entre trabalhar no mercado formal ou informal. / The aim of this study to estimate the probability of a worker being employed in the informal sector conditioned their productive characteristics, considering the possibility of sample selection bias. The sample is restricted to CearÃ, and uses the National Survey of Household Sample Survey (PNAD) in 2008 to classify workers in formal and informal. According to the dual hypothesis, the jobs in the formal sector are indeed better in many dimensions, and the existence of informality is because the number of these jobs is limited. If indeed there is segmentation in the labor market and rationing of formal jobs, it is important to know how the allocation of workers between the two sectors. For this is considered the possibility of selection bias in the choice between formal and informal sectors. The selection bias occurs when a number of unobservable characteristics of individuals can make them end up working, by choice or necessity, in the informal economy. That is, unobservable characteristics of individuals such as skill, willpower, determination, creativity etc., it may be influencing the choice between working in the formal or informal.

Esta pesquisa investiga os determinantes e a evolução recente no Brasil do trabalho remunerado feminino exercido no próprio domicílio ou simplesmente trabalho domiciliar. Quase 10% da população feminina ocupada, aproximadamente 4,5 milhões de mulheres, tem esse tipo de ocupação. Constatando a inexistência de estudos sobre o tema com dados quantitativos abrangentes, a presente pesquisa utiliza informações da Pesquisa Nacional por Amostras Domiciliares (PNAD) de 1992 a 2005 para analisar como evoluiu a proporção de trabalhadoras domiciliares no total da população ocupada. As mais importantes hipóteses delineadas na literatura a partir de estudos de caso são discutidas pela confrontação com os dados. Sob a ótica da demanda por essa forma de trabalho, analisa-se os setores que mais fazem uso do trabalho domiciliar feminino e as mudanças nessa composição, bem como sua relação com as transformações no mundo do trabalho decorrentes da reestruturação empresarial. Quanto à oferta por trabalho domiciliar, investiga-se como atributos individuais e familiares afetam as chances da mulher estar nesse tipo de condição de ocupação. É debatido como as transformações na inserção produtiva feminina afetaram a importância relativa do trabalho domiciliar. Constrói-se um modelo Logit Multinomial no Stata a partir dos dados da PNAD para comparar como mudou no tempo o impacto de cada atributo sobre a probabilidade de que uma mulher seja trabalhadora domiciliar. / This research investigates the determinants and recent developments of female home-based work in Brazil. Almost 10% of the occupied female population, approximately 4.5 million women, has this kind of occupation. Noting the lack of studies on the topic with comprehensive quantitative data, the present research uses information from PNAD beginning on 1992 until 2005 to evaluate how the proportion of female home-based workers on occupied population evolved. The most important assumptions outlined in the literature from case studies are discussed by confrontation with the data. From the perspective of demand for this type of work, sectors that intensively use female home-based work are analyzed, as well as its relationship with the changes in the labor market resulting from firms restructuring. On the supply of home-based work, it is investigated how individual and family attributes affect the chances of a woman to be in this work condition. It is discussed how the changes on female\'s productive insertion affected the relative importance of home-based work. A Multinomial Logit model is built on Stata using the data from PNAD to compare how the impacts of each attribute on the probability of a woman being home-based worker changed over time.
