In this paper, we combine data from Uber Movement and from a representative household travel survey to constructs a weighted travel time index for the Metropolitan Region of São Paulo. The index is calculated based on the average travel time of Uber trips taken between each pair of traffic zone and in each hour between January 1st, 2016 to December 31, 2018. The index is weighted based on trips reported in a household travel survey that was designed to be statistically representative of all trips made in the city during a typical business day. We show that the index has a strong correlation with traditional measures of congestion, however, with a broader coverage of the road network. Finally, we use the index to run a multivariate ex-post analysis that estimates the effect of different events on traffic congestion in the city, including holidays, public transit strikes, road shutdowns, rain and major sport events.

    Twenty years after negotiations began between Mercosur and the European Union (EU), a trade agreement between ministers was reached last Friday in Brussels. Its first phase, from 1999 to 2014, had among the motivations on the European side not to be left behind while the US then pursued a Free Trade Agreement for Latin America (FTAA). Symptomatically, such enthusiasm cooled after FTAA negotiations came to a halt and the United States embarked on bilateral agreements with some countr ...

    Empirical models of international commodity trade ows tend to show that exchange rate volatility has either no or negative impact on export volumes. This analysis has a number of limitations. In particular, it underestimates the role of physical traders and, consequently, the importance of future markets. In this context, this article aims to provide the theoretical underpinnings to demonstrate that these traders play a very particular role and that they have an influence on the rea ...

    There is no doubt that the ascension of China, which is at the centre of the global debate, is the most relevant fact of the 21st century. A rising power with many vulnerabilities, yet a clear understanding of what they are and with the willingness to actively reduce them to a minimum, manageable level. China has managed to become, after all, the second largest economy in the world, with outstanding economic performance. Globalisation has brought China from the periphery into the co ...
