MG, bem como examinar os efeitos das vari?veis determinantes em seu comportamento. Permite ainda uma compreens?o do cen?rio pesquisado, possibilitando, deste modo, analisar a magnitude de poss?veis pol?ticas tarif?rias utilizadas, sendo capaz de sustentar no processo decis?rio sobre a necessidade de investimentos, por meio de proje??es do consumo. Para esse fim, utilizou-se t?cnicas de an?lise explorat?ria temporal de dados, considerando o per?odo de setembro de 2012 a dezembro de 2014, dividida em duas categorias de consumo: social e normal. O modelo de demanda de ?gua apoiou-se na estrutura tarif?ria da Companhia de Saneamento de Minas Gerais (COPASA-MG), visando avaliar aspectos importantes tanto para o servi?o de abastecimento de ?gua quanto de consumidores. Ressalta-se a import?ncia das vari?veis pre?o m?dio, renda e clima, objetivando-se substancialmente em encontrar os par?metros de elasticidade. A compreens?o desses par?metros viabiliza uma an?lise do impacto de pol?ticas tarif?rias e possibilita a proje??o do consumo futuro de ?gua no longo prazo. Os resultados encontrados destacam a inelasticidade pre?o da demanda de ?gua para ambas categorias estudadas, apresentando coeficientes significativos para o pre?o marginal e a vari?vel diferen?a. A quantidade de ?gua defasada e a renda para ambas as categorias estudadas, n?o apresentaram o sinal esperado pela literatura; j? o clima, na categoria normal, o coeficiente n?o foi significativo estatisticamente; e na categoria social, o coeficiente mostrou-se significativo. Portanto, presume-se um maior conhecimento na estrutura tarif?ria da cidade, al?m da busca por vari?veis que expliquem melhor a demanda de ?gua. / Disserta??o (Mestrado Profissional) ?

It also allows an understanding of the researched scenario, thus making it possible to analyze the magnitude of possible tariff policies used, being able to sustain in the decision making process on the need for investments, through consumption projections. For this purpose, we used techniques for exploratory temporal data analysis, considering the period from September 2012 to December 2014, divided into two categories of consumption: social residential and normal residential. The water demand model was based on the tariff structure of the Minas Gerais Sanitation Company (COPASA-MG), in order to evaluate important aspects for both the water supply service and consumers. The significance of the variables average price, income and climate is emphasized, aiming substantially at finding the parameters of elasticity. The understanding of these parameters enables an analysis of the impact of tariff policies and enables the projection of future water consumption in the long term. The results found highlight the price inelasticity of water demand for both categories studied, presenting significant coefficients for the marginal price and the difference variable. The coefficient was not statistically significant, in the social category, the coefficient showed to be highly significant. The coefficient was not statistically significant, in the social category, the coefficient showed to be highly significant. Therefore, it is assumed a greater knowledge in the tariff structure of the city, besides the search for variables that better explain the water demand.

The thesis deals with possible impacts of non-zero rate of excise tax on still wine if applied on market subjects which means consumers, producers and the government. Function of price elasticity demand for wine in the Czech Republic is created and using regression analysis is found that demand for wines in the Czech Republic is inelastic. Original hypothesis that introduction of excise tax of 10 CZK per one litter of still wine would not positively impact any of affected subjects has not been confirmed. Demand for still wine would be reduced if excise tax was exercised and therefore producers and customers would be harmed but the analysis shows that the government would increase its tax collection. Another finding is that cheap wines are more price elastic and impact of tax growth on demand for these wines would be greater than in case of more expensive wines. Results of research are applied on the VINIUM Company and its financial statements with finding that introduction of excise tax would probably lead to bankruptcy of the company.

The main goal of this Diploma´s Thesis is to make a model for calculation of water and sewer rates for the company Vodovody a kanalizace Náchod, a.s. when sticking to the set criteria both from the side of VaK Náchod, a.s. and law regulations. Based on the theoretical part an analysis of customer sensitivity to the price changes using the data for last 20 years follows. Findings from the first two parts are used in risk analysis in next part. The created model calculates the water and sewer rates based on the information from the company accounting system in the way to generate sufficient financial resources to fulfill the renovation plan of infrastructural property plant and equipment and to transfer given amount to the company funds. In addition, the model monitors whether the legal condition of maximal allowable increase of profit per m3 is met. In the customer sensitivity to the price changes part the price elasticity of demand for water and sewer rates is calculated based on the data from 1995 to 2015. The assumption of inelastic demand is confirmed. Risk analysis part is deals with potential risk regarding the demand and prices. Potential impacts for the most significant risk are quantified. The analysis uses knowledge gained in the first two parts. It was confirmed that potential risks are exiting but do not have any significant impact on the going concern of VaK Náchod, a.s. The created model has been already used for the calculation of prices for the year 2017. Customer sensitivity analysis to the price changes and link to the potential risks is an additional information for VaK Náchod, a.s. which validates that nowadays, there are no significant threats which could affect the demand and water and sewer rates significantly.

The diploma thesis deals with the analyses of demand using standard tools of engineering mathematics. Mathematical models of demand, both single and multi- factor are investigated. Elasticity of demand is applied for decision making in price policy. Problems of optimization of demand reflecting utility and budget constraints are under consideration. Constructions of demand curve and compensated demand curve are presented. The text is accompanied by illustrative examples aiming at methodical aspects of the work

This suggests a broader and more systemic competition view, once consumer spending on a determined sector may be better understood if related to other sectors. Thus, it is reasonable to concentrate studies in the manifestation of the buyer behavior, expressed by the family budget, whereas priority/vital-based decisions are established according to how the consumers distribute their resources in great categories of expenses (food, housing, transportation, clothing, leisure etc). In this context, the main objective of this research is outlined, which is to investigate the phenomenon of the allocation of such expenses that compose the family budget, identifying patterns, market segmentation and its implication in Marketing. The theoretical referential is divided in three great parts: market segmentation, family budget, and the economic and socio-demographic factors that relate to the family budget. Maslow’s Classic Hierarchy of Needs is approached, along with themes from economics literature such as Engel’s Law and Income-elasticity of Demand. Using data collected from a sample of families in the State of São Paulo and applying Cluster Analysis, this study aims to bring a perspective that is more influenced by the paradigms of the market knowledge by identifying and characterizing market segments with distinctive patterns of family budget. A taxonomy based on six patterns was formed, which are: survival, ill, economic, domestic, well being and automobile. Each pattern analysis enhances economic and socio-demographic similarities and differences that demand the attention of researchers and marketing strategists concerning the generalization problems, which may result in mistakes in market segmentation strategies. Discussions concerning the Maslow’s Theory and Engel’s law are made. Furthermore, taxonomy of family expenses classified by the income-elasticity among the six identified family budget patterns is proposed. This taxonomy helps clarify changes in consuming behavior according to the impact in income alterations in the composition of the family budget. Finally, results reinforce the thesis that patterns in family expenses allocation present an innovative and useful dimension for studies in market segmentation. / Cada vez mais se reconhece que as diferentes categorias do orçamento familiar disputam recursos limitados de uma família. Isto sugere uma visão mais ampla e sistêmica de concorrência, já que os gastos dos consumidores em um determinado setor poderão ser melhor compreendidos se relacionados com os de outros setores. Faz sentido, então, concentrar estudos na própria manifestação do comportamento de compra, expressa pelo orçamento familiar, visto que as decisões mais prioritárias (vitais) estão estabelecidas na forma como o consumidor distribui seus recursos nas grandes categorias de despesa (alimentação, habitação, transporte, vestuário, lazer etc). Neste contexto delineia-se o principal objetivo desta tese que é investigar o fenômeno da alocação de despesas que compõem o orçamento familiar, identificando padrões, segmentos de mercado e suas implicações para o Marketing. O referencial teórico divide-se em três grandes partes: a segmentação de mercado, o orçamento familiar e os fatores econômicos e sócio-demográficos que se relacionam com o orçamento familiar. A clássica Hierarquia das Necessidades de Maslow é abordada, além de temas oriundos da literatura de economia como as Leis de Engel e elasticidade-renda da demanda. Utilizando dados de uma amostra de famílias do estado de São Paulo e valendo-se da técnica de análise de agrupamentos, a tese busca trazer um olhar mais influenciado pelos paradigmas do conhecimento mercadológico por meio da identificação e caracterização de segmentos de mercado com padrões distintos de orçamento familiar. Foi construída uma taxonomia composta por seis padrões assim nomeados: sobrevivência, enfermo, econômico, caseiro, bem-estar e automotor. A análise do perfil de cada padrão ressalta semelhanças e diferenças econômicas e sócio-demográficas que exigem a atenção dos pesquisadores e estrategistas de marketing quanto aos problemas de generalização, podendo resultar em erros nas estratégias de segmentação de mercado. Discussões dos resultados são tecidas a respeito da Teoria de Maslow e das Leis de Engel. Além disso, é proposta uma taxonomia de despesas familiares classificadas pelas elasticidades-renda entre os seis padrões de orçamento familiar identificados. Esta taxonomia ajuda a clarear as mudanças no comportamento de consumo segundo o impacto das alterações de renda na composição do orçamento familiar. Por fim, os resultados reforçam a tese de que padrões de alocação das despesas familiares se apresentam como uma dimensão inovadora e útil para os estudos de segmentação de mercado.
