This is based on a passed collection in the aggregate equity gain to private property by indirect influence of public works. The species used in their collection of assumptions limitation on total costs and individual benefits generated by consolidating the attempt to balanced supply of public goods and services at the lowest cost to society. Although the standard it's value increases, we identified that the correct terminology for the regulated object would increase the property's market price. The regulatory standard of the institute becomes useful in the world of facts for not having incentives to owners benefit to freely return what had been wrongly added, fitting tribute to the corrective action, and the sharing of burdens and realized bonus. And the same craving combat opportunism, there is the possibility that free gains arising to the affected owners, we have identified as an owner surplus. The need for identification of the popular collaboration on the implementation of the tax, it investigated empirically that the rule applies to your goals, but before the decision-making, treatment of the subject with the population may lead to inefficient choices. / Esta tese de mestrado aborda a verifica????o jur??dica e econ??mica da esp??cie tribut??ria intitulada contribui????o de melhoria. Este tributo ?? baseado em uma arrecada????o sob o ganho patrimonial agregado aos im??veis particulares por influ??ncia indireta de obras p??blicas. A esp??cie utiliza em seus pressupostos de arrecada????o a limita????o sobre custos totais e os benef??cios individuais gerados, consolidando a tentativa de oferta equilibrada de bens e servi??os p??blicos, ao menor custo para a sociedade. Embora a norma trate de acr??scimos de valor, identificamos que a terminologia correta para o objeto regulado seria aumento de pre??o de mercado do im??vel. A norma reguladora do instituto se faz ??til no mundo dos fatos por n??o haverem incentivos aos propriet??rios beneficiados para livremente devolver o que fora agregado indevidamente, cabendo ao tributo a a????o corretiva, e a reparti????o de ??nus e b??nus concretizados. E, mesmo almejando combater o oportunismo, h?? a possibilidade de que ganhos livres surjam aos propriet??rios afetados, o que identificamos como um excedente do propriet??rio. Da necessidade de identifica????o da colabora????o popular sobre a implementa????o do tributo, investigou-se empiricamente que a norma ?? v??lida aos seus objetivos, mas diante da tomada de decis??es, o tratamento da tem??tica com a popula????o pode conduzir a escolhas ineficientes.
