ResumoO objetivo deste trabalho é projetar os impactos econômicos, nacionais e regionais dos investimentos de infraestrutura e estádios para a Copa do Mundo de 2014. Consideram-se os investimentos em reforma/ construção de infraestrutura esportiva (estádios) e infraestrutura urbana divulgados pelo Ministério do Esporte no início de 2010. Por meio de simulações com um modelo de equilíbrio geral, são projetados os impactos das fases de construção e operação desses investimentos, com atenção especial às fontes de financiamento (público, privado e BNDES). Os resultados apontam para um crescimento adicional médio de 1,2% no PIB das cidades-sede e a geração do equivalente a 158 mil empregos. A análise dos resultados indica, entretanto, que o impacto positivo desses investimentos depende da capacidade de financiamento privado e das necessidades de realocação do gasto público. Quanto maior a utilização de recursos públicos no financiamento dos investimentos da Copa 2014, menor seu impacto econômico.

We consider the investments in renovation/construction of sports infrastructure (stadiums) and urban infrastructure published recently by the Ministry of Sports. The impacts of construction and operation of those investments are projected through simulations with a computable general equilibrium model, with special attention to funding options (public, private and BNDES).

Dairy farming is an important aspect of the Brazilian agricultural sector. The presence of numerous producers has created a large number of jobs in this field, contributing significantly to the rural economy. Artificial insemination (AI), used as one of the main means of reproduction, is increasingly gaining importance in the genetic improvement of animals. Given this scenario, the semen of bulls has become extremely marketable and an important aspect of the animal industry. This study aims to develop a hedonic model for the price of semen doses of dairy bulls based on the information from the main sellers of the product in the Brazilian market. The main findings reveal that there is an additional premium for proven bulls. Semen doses from Gir bulls proved to be more expensive, and the AI firm ALTA has a discount compared to the other firms. From the characteristics obtained in the tests, there is a premium only for the Predicted Transmitting Ability–Milk (volume). The most valued feature found is the dose being sexed, that is, the dose that guarantees the gestation of a female from its use. Semen doses from dead bulls has proved to be more expensive.
