Sharing

At the interface between academic research and society, AMSE disseminates economic knowledge to non-academic audiences by:
- making the results of research accessible to everyone through its digital journal, Dialogues économiques, which publishes articles, videos and infographics,
- organizing outreach events (conferences, festivals, exhibitions),
- supporting researchers to contributing to the public debate (journalistic writing, press relations).

Exchange Rate Targeting in Sub-Saharan Africa: Real, Nominal, or Mixed?

With little diversification, a great amount of debt, and a high level of dependence, the economies of Sub-Saharan Africa are confronted with many challenges and left vulnerable against external shocks. What exchange rate regimes do central banks choose to protect these countries and help them reach seemingly incompatible macroeconomic aims?

The Growth Rate of Cities: From Agricultural to Industrial Towns

According to the World Bank, cities account for only 55% of Earth’s population, and generate more than 80% of the global GDP. They also often have a high economic growth. An Oxford study estimated Paris’ growth rate between 2019 and 2035 to be approximately 1.7%. But how can we explain this urban economic growth? The economists Christian Ghiglino, Kazuo Nishimura, and Alain Venditti aim to respond to this question by using a model that combines two major economic theories.

The Balance Between Labor and Capital: Do Profits Consume Wages?

How are wages decided upon? One major determining factor is how value added is shared between a company’s profits and employee compensation. It has been collectively admitted that over the past forty years, profits have increased in many developed countries at the expense of wages. Economists Gilbert Cette, Lorraine Koehl, and Thomas Philippon look at this in a new light and demonstrate that the percentage for wages has actually increased in France.

Students Prefer Accredited Schools!

How can you set yourself apart within a world of excellence? In order to be noticed and attract the very best students, elite French business schools, much like peacocks, show off their finest attire. However, when it comes to the strategy institutions use to win over students, a new element is quickly gaining traction: accreditations! The economists Mathieu Lefebvre and Julien Jacqmin explore this new tactic.

Risky Workplace: Reserved for Immigrants

Not all is equal between natives and immigrants in the labor market. Beyond wage differences, immigrants also tend to work in more dangerous jobs and face difficult working conditions. According to the economist Eva Moreno Galbis, this difference can be partially explained by outside employment opportunities and preferences driven by socio-demographic characteristics.

In Favour of the Majority

What could be more natural than reaching agreement by following the preference of the majority? Mihir Bhattacharya and Nicolas Gravel study the issue through a mathematical lens. They show that, in addition to its philosophical legitimacy, the majority is a collective preference representative of the preferences of the members of a society. Like the average, the median, or other statistical measures, the preference of the majority bears the closest resemblance to the individual preferences from which it emanates.

May God Bless You! (If you pay)

For both insurance and divine protection, giving to the church can pay off. This is what economists Emmanuelle Auriol, Julie Lassébie, Amma Panin, Eva Raiber, and Paul Seabright demonstrate after studying the reasons why Ghanaian parishioners often give such large donations (sometimes over 10% of their income!) to their churches.

The general practitioner shortage: a French disease?

France is suffering from a shortage of general practitioners. One of the symptoms of this sickness has been termed 'medical desertification'. But what lies behind this expression? The economists Julien Silhol, Bruno Ventelou and Anna Zaytseva overthrow the assumptions in their latest publication. They reveal a little-known truth: inequalities exist in access to care from one end of France to the other, and not only in rural areas. An in-depth study is conducted into the practices of general practitioners in these areas defined by the ARS as 'under-provisioned': do these medical practices differ according to location?

From Protecting Nature to Protecting Biodiversity: A History of Debate

How do you measure a concept as obscure as biodiversity? Indicators are one way to do so. But the economists Pierre Courtois, Charles Figuières, and Chloé Mulier reveal that these may not all lead to the same result. For example, Calyampudi Radhakrishna Rao's and Martin Weitzman’s indicators each lead to policies that are sometimes on complete opposite sides of the spectrum. While one recommends saving the most fragile species, the other recommends saving the most robust! So, does protecting the environment come down to perspective?

Differing beliefs about common societal issues: what are the outcomes?

Reducing overall plastic consumption, vaccinating enough people to curb a pandemic, or donating to charity – these are all divisive issues. If I want to contribute, will my actions make any difference? What cost am I willing to pay? Economists Nicolas Gravel and Anwesha Banerjee study the extent to which an individual’s beliefs on issues such as these can influence the actions taken. Their research shows that the more closely a group's members are aligned on an issue, the more likely the group is to act toward the public good.
