Este crescimento se deu por meio de grandes investimentos em subsidio como forma de aumentar a atratividade dos aparelhos celulares comercializados nos pontos de venda. Estes investimentos ao mesmo tempo em que aceleraram a captação de novos clientes comprometeram a rentabilidade deste segmento e da margem EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) consolidada do setor no Brasil quando comparada a outros países. Portanto, um entendimento apropriado dos atributos mais valorizados pelos consumidores no processo decisório de compra de um aparelho celular é de fundamental importância para melhorar a alocação dos recursos e maximizar o retorno, sem perda de mercado. Este trabalho aplica a Metodologia de Preços Hedônicos como ferramenta para auxiliar na identificação dos atributos relevantes dos aparelhos celulares comercializados no mercado de massa brasileiro e seus respectivos preços implícitos. São 96 aparelhos celulares monitorados semanalmente ao longo do ano de 2007, constituindo mais de 37.000 registros. Como resultado, no estágio de maturidade do mercado na época, foram identificados intensos prêmios de preço associados às características físicas (design) e à presença de atributos relacionados à itens de multimídia (câmeras digitais, vídeos e MP3 player). Por fim, utilizamos o modelo econométrico desenvolvido para simular e identificar o preço sugerido ou potencial de novos celulares, não presentes na amostra utilizada para a regressão, mas constituídos por novas combinações de atributos com preços implícitos já identificados. / The mobile telecom market in Brazil is one of the largest in the world, consequence of a substantial growth in the prepaid segment. This growth was achieved at expense of intensive investments in subsidies in handsets, which were used as leverage to market position in the retail channel. These investments, at the same time in which accelerated the client’s acquisition, compromised current profitability levels and the consolidated EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) margin in Brazil when compared with other countries. Therefore, a deep understanding with respect to the most valuable attributes under the consumer´s perspective in the consumption decision process is a critical theme in order to improve the efficiency in the resource allocation (handsets subsidies) and to provide incremental returns, without losing market share. This study applies the Hedonic price Methodology as a tool in order identify the most relevant attributes and its implicit prices, both related to the most relevant handsets traded in the Brazilian mass market. This universe encompasses 96 handsets with weekly price updates monitored in 2007, resulting in more than 37.000 records. As a result, relevant premium prices associated with physical characteristics (design) and multimedia features (digital camera, video and MP3 player) were identified and quantified through its implicit prices. Finally, the econometric model developed in this study is applied in a real situation in order to simulate and to identify the suggested or potential prices associated to new handsets, not used previously in the regression model, but composed of new combinations of attributes already identified and quantified.

A análise destes preços, que não são isoladamente transacionados nos pontos de venda, mas que são indiretamente praticados em equilíbrio de mercado, é de fundamental importância para o entendimento dos critérios de decisão e do comportamento do consumidor. O modelo mostra, entre outras conclusões, que o mercado brasileiro valoriza vinhos mais encorpados, com longa permanência em barris de madeira, que têm como sugestão de uso a guarda (e não o consumo imediato) e que são procedentes, nesta ordem, da França, Itália, Portugal e Espanha. / Given the complete transformation that the Brazilian wine market has gone through in the last decade, and its still great growth potential, this work intends to identify, using the Hedonic Prices Methodology, the implicit prices of label, sensory and informative characteristics of wines in the Brazilian market. The analysis of such prices, which are not individually practiced, but that are indirectly negotiated in market equilibrium, is of great importance for the understanding of the consumers‟ decision criteria and behavior. The model shows, among other conclusions, that the Brazilian consumer values wines that are full-bodied, which stayed for long period in oak barrels, which have cellaring potential (as opposed to those which are to be consumed immediately), and that were produced in France, Italy, Portugal and Spain, in this order.

Esse programa objetiva implantar uma série de medidas estruturais, direcionadas à elevação das condições de habitabilidade da população residente em assentamentos urbanos localizados na Região Metropolitana de Salvador (RMS) e em Feira de Santana. Analisa-se a valorização dos imóveis residenciais situados nessas localidades, em função da presença do projeto, apurando os benefícios sob o ponto de vista econômico-financeiro. Os resultados alcançados com a utilização da metodologia de Preços Hedônicos demonstram que o incremento no preço do imóvel está associado a um maior número de atributos, e que o projeto é viável sob a ótica econômico-financeira, considerando que as taxas internas de retorno (TIR) foram superiores à taxa social de desconto de 12% a.a. e à taxa de atratividade de mercado de 10% a.a. / The present work aims at the application of the Hedonic Price Method (MPH) in the economic financial evaluation of social projects of sanitation infrastructure in the city of Salvador-Bahia, under the Integrated Development Project in Urban Areas in the State of Bahia. This program aims to implement a set of structural measures aimed at increasing the living conditions of the population living in urban settlements located in the Metropolitan Region of Salvador (RMS) and Feira de Santana. The valuation of the residential properties located in these localities is analyzed, due to the presence of the project, assessing the benefits from the economic-financial point of view. The results obtained with the Hedonic Price methodology show that the increase in property prices is associated with a greater number of attributes, and that the project is feasible from the economic and financial perspective, considering that the internal rates of return (IRR) were higher than the 12% per year social discount rate and the market attractiveness rate of 10% per year.

近年來影城結合商場、娛樂及餐飲，如雨後春筍般出現，建商售屋亦常以影城為吸睛廣告，對消費者而言，影城對周邊住宅價格影響是否存有關聯性係其購屋選擇關心條件之一，然而現今影城的類型大不相同，且觀察到影城大多座落於商圈內或是與百貨商場結合。因此，本研究將影城、商圈與住宅價格的相關程度做交叉分析，以初步了解其關聯程度，並應用集群分析以控制異質樣本，使得形成同質性的房屋屬性來看影城效果，再透過複迴歸模型分析，探討不同類型的影城、商圈與周邊住宅價格之影響關係。 透過複迴歸模型實證結果得知，影城對台北市周邊住宅價格是有影響的，以總價1,000萬元房屋，平均而言，正向的價差介於41萬元至310萬元之間，負向的價差則介於30萬元至271萬元之間，並且正向的價差高於負向的價差。進一步將影城依經營模式及服務方式分類進行實證，採連鎖經營模式的影城周邊房價價差約為40萬元，而提供複合式服務或僅提供單一式服務的影城，對房價的影響差別不大。該結果可提供消費者在評估購買房屋時之參考，亦可作為開發商與銷售業者在預售屋訂價策略及廣告遵循原則。 此外，由於消費型態的改變，消費者習慣將看電影結合其他休閒活動，這些由百貨公司以及電影院異業結盟的商圈更得消費者青睞，影城進駐與商圈發展之關係相輔相成，進而影響新北市周邊住宅價格，以總價1,000萬元房屋，平均來說，影城進駐商圈後能提升房價139萬元。 / These years combination-area of cinemas, malls, recreation and catering are springing up as well as being the eye-catching advertisement of building-contractors. In terms of house-buyers, the correlation between cinemas and the neighborhood housing price is one of the conditions they care. Nevertheless, with the variety of the cineplex-cinema currently and mostly locate in business districts and department stores, our study make a cross analysis between cineplex, cinema, business districts with residential price for their correlation. With cluster analysis to control the heterogeneous samples and to evaluate the price-effect of cineplex-cinemas under the homogeneous housing. Furthermore to multiple regression analyze cinema stationed-in commercial-district and their neighborhood housing price. Our study confirmed the cineplex-cinemas are influential to the Taipei City surrounding-area residential price. For the ten million house, averagely the positive-impact is between four hundred ten thousand to 3.1 million. Negative-impact is between three hundred thousand to 2.71 million. Besides, the housing price different positive effect is higher than the negative one. Further to verify type-mode cinemas: the price difference in neighborhood-area is four hundred thousand with franchise management type-mode. However, there is no price difference with complex and single-service type-mode. Housing-buyer can take the result as consideration during purchasing houses as well as real estate developers and salesman in pricing strategy and advertisement principles of pre-sale houses. Additionally, with the change of consumption patterns, consumers get use to watch movies together with other recreation. Thus commercial-districts combining with department stores and cinemas are more favored. The cinema stationed-in and commercial-district development are complemented each other, therefore to affect the neighborhood housing price in New Taipei City. For the ten million house, averagely, the positive price-different effect is one million and three hundred nighty thousand after the cinema stationed-in.

Les activités économiques présentent des formes et des degrés de dépendance variables à l’environnement. L’environnement peut intervenir comme un facteur de production, comme une contrainte à l’usage de certains intrants, comme une contrainte pour certains facteurs de production. La dépendance peut être reliée à la disponibilité ou à la qualité de certaines ressources environnementales, à leur dimension de bien collectif. Il s’agira d’explorer les implications des différentes formes de dépendances bio-physico-chimiques mais aussi juridiques. Dans le cas de l’ostréiculture arcachonnaise, on examinera les formes de dépendance et leur mesure économique, à travers les impacts économiques liés à la disponibilité variable des ressources biologiques marines mais aussi à la productivité naturelle du milieu. L’analyse des caractéristiques socio-économiques des entreprises ostréicoles arcachonnaises permettra de dresser une typologie de ces dernières et ainsi caractériser l’activité. Une approche par la fonction de production sera utilisée pour mettre en évidence les degrés divers de sensibilité à une variation des conditions environnementales de production tandis que l’évaluation par la méthode des prix hédoniques permettra de déterminer le prix implicite des composantes environnementales des indemnités de substitution en tenant compte par ailleurs de la localisation géographique des concessions ostréicoles. / Economic activities have forms and degrees of dependency variables to the environment. The environment can act as a factor of production as a constraint to the use of certain inputs, such as a constraint for some inputs. Dependence may be related to the availability or quality of certain environmental resources. It will explore the implications of different forms of dependencies bio-physico-chemical as well as legal. In the case of the Arcachon Bay oyster-farming will examine the forms of dependence and economic measure, through the economic impacts associated with the variable availability of living marine resources but also to the natural productivity of the environment. The analysis of socio-economic characteristics of Arcachon Bay oyster-farms will develop a typology of the latter and thus characterize the activity. A production function approach will be used to highlight the varying degrees of sensitivity to changes in environmental conditions of production while the evaluation by the hedonic price method will determine the implicit price of environmental components of the oyster leases value taking into account also the geographical location of oyster leases.

The housing market segmentation could provide a reference for more targeted policymaking and investment strategies. Although there have been many studies, there are no consistent submarkets delineating methods because of a lack of theoretical support and subjective evaluation. In this paper, two market segmentation methods are introduced. The continuous spatial segmentation divides properties into submarkets according to their coordinates, while the discontinuous spatial segmentation creates submarkets according to the variable having the most significant impact on the price index, which is the construction year of properties. Two valuation methods, the hedonic price model and the XGBoost regression model, are applied to evaluate the overall Stockholm housing markets and the created. The results proved that both market segmentation methods could improve the valuation prediction accuracy compared to the valuation under the overall Stockholm housing market. The non-spatial continuous market segmentation approach delivers more improvement in valuation accuracy but also has greater volatility. As for the two valuation models, no single valuation method can be absolutely advantageous in any market context. / Segmenteringen av bostadsmarknaden skulle kunna utgöra en referens för mer målinriktade politiska beslut och investeringsstrategier. Även om det har gjorts många studier finns det inga konsekventa metoder för att avgränsa delmarknader på grund av brist på teoretiskt stöd och subjektiv utvärdering. I detta dokument presenteras två metoder för marknadssegmentering. Den kontinuerliga rumsliga segmenteringen delar in fastigheter i delmarknader utifrån deras koordinater, medan den diskontinuerliga rumsliga segmenteringen skapar delmarknader utifrån den variabel som har störst inverkan på prisindexet, vilket är fastigheternas byggnadsår. Två värderingsmetoder, den hedoniska prismodellen och XGBoost-regressionsmodellen, används för att utvärdera Stockholms bostadsmarknad och den skapade marknaden. Resultaten visade att båda marknadssegmenteringsmetoderna kunde förbättra värderingens prediktionsnoggrannhet jämfört med värderingen under den övergripande bostadsmarknaden i Stockholm. Den icke-rumsliga kontinuerliga marknadssegmenteringsmetoden ger större förbättringar i värderingsnoggrannheten men har också större volatilitet. Vad gäller de två värderingsmodellerna kan ingen enskild värderingsmetod vara helt fördelaktig i något marknadssammanhang.

The construction and real estate industry accounts for a large share of the global energy consumption. Thus, an onerous responsibility is resting on the shoulders of the property owners and developers to alleviate the emissions derived from the real estate sector. With the escalating necessity for undertaking measures aimed at averting additional negative impact on the climate, a rising level of engagement from governmental as well as private stakeholders emerges. As a consequence of the negative development in the sector, and with tenants willing to pay rentalpremiums to be seated in premises in buildings certified as green, the issuance of green certifications have surged. The purpose of this study is to examine whether the distance from the city center has an impact on the green sales premiums for commercial office properties on the Swedish property market, to be able to compose more accurate calculations of green investments. This is investigated ona national level, as well as for cities exceeding 200,000 inhabitants. The study is a quantitative study which uses hedonic regression models to answer the research questions. The data used is collected through a transaction database provided by Cushman & Wakefield Sweden, with additional data from Sweden Green Building Council and Statistics Sweden, among others. The results conclude an incremental green premium of 14.80% at the 1 km mark from the city center for the country level data set, and 31.92% for the larger cities, at the 10%, respective 1% level of significance. However, some coefficients are inconsistent and the author highlights potential deficiencies within the course of action. / Bygg- och fastighetssektorn står idag för en stor del av den globala energiförbrukningen. Därmed vilar ett tungt ansvar på fastighetsutvecklare, förvaltare och andra aktörer i branschen för att minska utsläppen från fastighetssektorn. Med det ökande behovet av att vidta åtgärder för att undvika ytterligare negativ påverkan på klimatet, har även engagemanget från både offentliga och privata aktörer tilltagit. Som en konsekvens av den negativa utvecklingen inom sektorn och att hyresgäster är villiga att betala en premie för att husera i byggnader som är miljöcertifierade, har utfärdandet av gröna certifikat ökat markant. Syftet med denna studie är att undersöka om avståndet från centrum har en inverkan på den gröna försäljningspremien för kommersiella kontorsfastigheter på den svenska fastighetsmarknaden, för att kunna göra mer exakta investeringskalkyler gällande investeringar i miljöcertifierade fastigheter. Detta undersöks på dels nationell nivå, och dels för städer med över 200 000 invånare. Studien är en kvantitativ studie som använder hedoniska regressionsmodeller för att besvara forskningsfrågorna. Dataseten komponeras med hjälp av en transaktionsdatabas som tillhandahålls av Cushman & Wakefield Sweden, tillsammans med ytterligare data från bl.a. Sweden Green Building Council och Statistiska centralbyrån. Resultatet indikerar en ökande grön premie om 14,80% vid 1 km från stadens centrum för datasetet på nationell nivå, och 31,92% för de större städerna, vid 10% respektive 1% signifikansnivå. Vissa koefficienter är dock inkonsekventa och författaren lyfter fram potentiella brister i handlingsförloppet.

國內近年來有許多文獻在進行特徵價格模型預測時，避免樣本中存在異常點會造成模型估計值產生偏差，會使用統計軟體進行異常點檢測，但皆是直接將檢測出的異常點刪除，未加以著墨探究這些異常點的特徵結構、成因及特色等。因此，本研究透過統計檢定方法，探討刪除異常點前後整體樣本的特徵結構變化，並以個別估價觀點加以探討住宅交易樣本異常點的成因與特色，藉此歸納出實價登錄資料未揭露的重要特徵，以及迴歸模型搜尋疑似申報不實案件之可行性。 透過敘述統計及樣本結構差異檢定結果發現，異常樣本的離散程度相對原始樣本與正常樣本較大，且經過刪除異常點的正常樣本特徵結構差異程度縮小；異常點的形成可能受到區位變數無法反映實際情況及樣本群聚程度影響，也可能因模型未納入某些重要的特徵變數，而使隱含該變數的樣本被判斷為異常點；異常樣本與正常樣本的成交總價、土地坪數、建物坪數、總樓層、所在樓層及屋齡等變數平均數、變異數及中位數有顯著差異。 藉由個案分析結果歸納，可能因異常個案的住宅屬性存在整幢大樓住商混合使用、特殊鄰居、附屬建物占比過高、高總價豪宅產品、都更效益、增建效益、裝潢效益、約定專用空間效益、樓層高度挑高、獨特視野景觀或特殊區位條件；外部環境存在鄰近嫌惡設施或迎毗設施；交易情況存在買方身分特殊之影響，但受限於實價登錄未要求登載並揭露這些特徵，故模型未考量這些因素對價格的影響，使得模型可能將隱含這些特徵的樣本判斷為異常點，並進而影響模型預測結果。另外也發現，實價登錄資料存在登載錯誤及價格申報不實的情況，且可能被模型判斷為異常點。 / Many literatures use statistics-way to detect outliers in preventing any extreme deviation in hedonic price model prediction. Nevertheless, deleting the outliers instead of investigation into the structures, causes and features. Hence, this thesis studies the feature structures variation of the sample before and after deleting the outliers and with the valuations by appraisers’ perspective to inquire into the factors and features of the outliers in residential transactions. Thereby to summarize the significant features that are not disclosed by real price registration and feasibility in searching the possible false declaration of price by regression. Through descriptive statistics and sample structural difference parametric and nonparametric test shows the discreteness level of singular (outliers only) samples is greater than the primary (outliers including) and normal (outliers deleting) samples and the feature structure variation lessened after deleting the outliers in normal samples. The formation of outliers may be influenced by location variable not able to reflect actual circumstances and level of clustering in samples. Maybe some significant variables are not subsumed into the model, which leads to the judgement of samples with this variable to be outliers. The mean, variance and median in total traded price, land size, building size, total floors, exact floor and house age of singular samples are notably different with normal ones. With the analysis of cases, the possible reasons may be residential and commercial mixed-use in building, peculiar neighbors, high proportion of accessory building, luxury houses, urban renewal benefits, building addition benefits, interior decoration benefits, agreed space benefits, high-ceiling benefits, unique view or location, YIMBY and NIMBY property in environment and special relationship between the buyer and seller. Nevertheless, due to the nondisclosure of these features in real price registration that the model does not take these into consideration. That leads to the judgement of samples with these features as outliers and affects the model prediction. Also the registration error and false declaration in price may also be judged as outliers.

This thesis deals with residential real estate market in the Austria and its development. The theoretical part defines the basic concepts of valuation, such as flat, family house, usual price, valuation legislation, expert opinion and summary methods of residential property valuation in Austria. The other part is targeted of the property market. The practical part deals with valuation of real estates in selected ways. In thesis attachment is processed an exemplar of the evalution report for a flat according to the standards and the methodologies used to by the evaluation in the Austria.
