In the United States, student debt is skyrocketing, and young people are saddled with surging interest rates on their loans. It is not uncommon for Americans to start their career already $100,000 in debt. However, an investment in human capital (education) is, in theory, a productive investment. Economists Xavier Raurich and Thomas Seegmuller demonstrate this by analyzing how the speculative bubbles individuals use to finance their studies or raise children are, in the end, good for growth.

Speculative bubbles are good for growth! This observation led to major debates among economists in the 2000s. Researchers Xavier Raurich and Thomas Seegmuller sought to explain this phenomenon by studying how economic agents make investment decisions during the periods of their life as young adults, middle-aged adults, and retirees. Young people can therefore invest in their education, which is a productive but illiquid capital, through credits from the bubble (liquid assets stemming from speculative capital).

What is the common feature between global imbalances, the Crédit d’Impôt pour la Compétitivité et l’Emploi (CICE), and Donald Trump's tweets against China? Competitiveness! This concept has been at the heart of political discourse since the European debt crisis in 2010, leading to much scrutiny of its performance and praise of its growth. So, when it comes to reforms aimed at increasing competitiveness, economists Lise Patureau and Céline Poilly point out the importance of considering the impact of corporate markup.

A team of researchers in economics elicited population preferences regarding the main anti-Covid 19 strategies in France. The scientific article is published in The Lancet Public Health.

When an individual is afflicted with several chronic conditions at the same time, it is called multimorbidity. This is an increasingly common problem in Europe. How do general practitioners deal with it? How do they manage prescriptions that are not only vastly different but can lead to damaging drug interactions? These questions are explored by researchers Hélène Carrier, Anna Zaytseva, Aurélie Bocquier, Patrick Villani, Hélène Verdoux, Martin Fortin, and Pierre Verger in an article that examines the attitudes and practices of private general practitioners.

Invasive species are the second most frequent cause of global biodiversity loss, and financial consequences in Europe are estimated at 12 billion euros per year. Is it possible to eradicate these devilish pests with limited financial resources? To help identify priorities in such battles, a method is offered by authors Pierre Courtois, Charles Figuières, Chloé Mulier et Joakim Weill, which is based on interactions between different species.

In an op-ed in Le Monde, the teacher-researcher in economics Karine Gente (AMU, FEG) is indignant of the inequality created in higher education by the difference in treatment between university students and future students of 'grandes écoles'.

According to game theory, free competition is not always ideal for society. Economists Gaëtan Fournier and Marco Scarsini use this perspective to study the spatial competition between several retailers. The retailers choose the location of their business to maximize their profits. According to the researchers’ model, pursuing an individual profit leads to stable but undesirable situations for the common good.

How many people are living in poverty in the world? Finding the answer to this simple question poses a wealth of difficulty. Determining who lives in poverty is a difficult task, and the various means used to count these people can give quite different values. Economists Zhou Xun and Michel Lubrano seek to illustrate this issue in their article, in which they propose a new method for assessing poverty in developing countries.
