Title: Políticas de Custeio Extra Tarifário do Transporte Público Brasileiro: Internalizar Externalidades é Preciso
Abstract: This article sought to evaluate urban public transport costing policies using progressive and Pigouvian extra-tariff sources (who pollutes more, pays more). This strategy aims to make the transit more competitive in relation to individual transport, improving the sustainability conditions of the urban mobility system. It was observed that these measures present strong political resistance due to inflationary impacts and increased spending by the richest families. On the other hand, when analyzing issues related to social costs and equity, these measures present excellent results, as the benefits are greater than the costs and there is a clear policy of abatement of externalities by the wealthier classes. As a consequence, there is an improvement in the mobility conditions of the poorest and in the sustainability conditions of the entire mobility system.

Title: Avaliação da Eficácia da Política de Garantia de Preços mínimos para o Milho em Grãos
Abstract: The Minimum Price Guarantee Policy (PGPM) has, among its objectives, the guarantee of a minimum income for rural production by reducing the risk of negative variations in the price of the product served by the policy. The present work presents an analysis of the effect of the policy on corn grain prices in the State of Mato Grosso. It presents a literature review on the effectiveness of the PGPM, followed by an analysis for the data of the time series of prices according to corn in grains, in relation to time series referring to the policy instruments. A multiple regression model with ARIMA residues was used, as well as a quantile regression model, incorporating the ARIMA model. The results demonstrate an ineffectiveness of the public policy and, so, this article concludes with possible hypotheses for this finding and contributions to further researchs.
