90 Seconds of Science with Professor Antonieta Cunha e Sá

90Professor Antonieta Cunha e Sá addresses the impact that land conversion at the border of urban and non-urban areas, for development or for agriculture, can have on the environment and the ecology of the site, in Antena 1’s radio program 90 Seconds of Science, on August 28th 2017.

This problem is important "because these border regions are areas that undergo a great deal of pressure from developmentalists, that has to do with population growth, income increase, but also because of market failures", justifies Antonieta Cunha e Sá. Presented with these reasonings, an owner who has a plot of land and who exploits wood in that region, ends up having great incentives to convert the land.

However, these conversions have important consequences not only in terms of nature and ecology, but also in economic and social terms. Additionally, "it also makes wildlife in these regions more difficult to coexist: there is habitat destruction, fire risk increases, air quality is affected, environmental quality is affected. So there are indeed many negative aspects to the destruction or conversion of land, "warns Antonieta Cunha e Sá. This conversion can be done for urban or even industrial development, or for agriculture. In the first case, land conversion becomes irreversible: "There is an irreversibility aspect here that makes the problem even more complex or more serious, so to speak," she concludes.

90 seconds of science - Professor José Tavares

90A study reveals that implementing a gender quota in a democratic political system is only effective if it is high enough to convince the best qualified women to compete. A share of less than 25% may be ineffective in capturing the interest of potential female candidates.

José Tavares, professor at Nova SBE, together with Paulo Júlio, a former PhD student at Nova SBE, published the paper "The good, the bad and the different: Can gender quotas raise the quality of politicians?" in Economica journal which characterize the effects of a political gender quota in a citizen-candidate model.

90 seconds of science with Luís Catela Nunes

90 seg de cienciaLuís Catela Nunes is a professor at Nova SBE and investigates the impact of school retentions on a student's academic life.

"If a student had not been detained, what would have happened? Would he be better or worse?” These are the fundamental questions of the research published in the report from Fundação Francisco Manuel dos Santos, which studied students from Portuguese public schools attending the fourth year. The report was published together with two other co-authors, Carmo Seabra and Ana Balcão Reis, both professors at Nova SBE.

90 seconds of science with Miguel Ferreira

90Miguel Ferreira, professor at Nova SBE, developed this study within the scope of the Elections project in order to understand what influence banks and financial intermediaries may have on the economy.

"The Elections project is about trying to see whether financial intermediaries and banks have too much influence, too much power, on the economy, and in this project we are trying to see if the rating changes taken by the agencies can have an effect on the election results of Municipal elections in the US ", he says.

Knowledge in Motion with Pedro Brinca

The fourth video from the series "Knowledge in Motion" is based on the publication “Fiscal multipliers in the 21st century” from the Journal of Monetary Economics, where Prof. Pedro Brinca explains that fiscal multipliers are highly sensitive to the fraction of the population who face binding credit constraints and also to the average wealth level in the economy.
