Bilateral International Investments: The Big Sur?
Using country-to-country data, this paper documents a set of novel stylized facts about the rise of the South in global finance. The paper assembles comprehensive bilateral data on cross-border bank loans and deposits, portfolio investment in debt and equity, foreign direct investment, and international reserves. The main findings are that between 2001 and 2018 investments involving the South, and especially within the South, have grown faster than those within the North. By 2018, the South was involved in 34% of total international investments. The largest increases occurred in portfolio investment and international reserves, the smallest in banking. The growth of financial investments involving the South is often faster than that of GDP. These developments are observed across subregions of the South, beyond China and independently of offshore financial centers. The intensive margin contributed more than the extensive margin to the increasing weight of the South in international investments.

Interdependent Values in Matching Markets: Evidence from Medical Programs in Denmark
This paper studies interdependent values in a matching market and how market participants strategically adjust to this situation. We study these questions in the market for medical school programs in Denmark, which assigns students to programs based on a centralized assignment mechanism. Using administrative data on student preferences, college priorities, and student outcomes, as well as exploiting an information experiment, we present evidence that students and rival programs hold payoff relevant information that would, if known by the program, allow the program to admit students with lower program dropout rates. Building on these insights, we estimate an empirical model of this matching market that allows for heterogeneous program and student preferences as well as two sources of interdependent values: student self-selection and interdependent program values. Our findings suggest that both sources play a role and that programs benefit from learning information rival programs hold as well as learning about student preferences in identifying students with higher completion rates.

Personalized Pricing with Inequality Concerns
écrit avec Victor Augias (Sciences-Po) ; Daniel M.A. Barreto (Sciences-Po).
We analyze the redistributive consequences of a monopolist who can obtain additional information about consumers' tastes beyond the prior distribution, and thus implement personalized pricing. We study the problem of a social planner, who can commit to an information policy and has redistributive preferences. The latter is captured by a social welfare function that put higher weights on poorer consumers. We show that for sufficiently strong redistributive preferences, the social planner will sacrifice richer consumers' surplus and gives additional profits to the monopolist.

Between- and within-household consumption of ultra-processed food in France
Ultra-processed food consumption has been recently associated with the prevalence of obesity and non-communicable chronic diseases such as some types of cancers, diabetes and heart diseases. However, ultra-processed food consumption is not so-well documented across individuals or across food product categories. In this paper, we construct a unique longitudinal dataset, between 2002 and 2015, of at-home food consumption of French households to which we merge information regarding nutritional values and degree of food processing. Over the period, we find increasing consumption patterns of ultra-processed products, yet still relatively low when compared to Anglo Saxon countries levels of consumption. French lower consumption levels are most likely a result of higher prices for ultra-processed products relatively to less-processed products, the reverse of Anglo saxon prices. We then develop a panel data econometric analysis to identify the determinants of ultra-processed food consumption exploiting the within- and between-household variations. We find that socio-economic demographics would explain more the between household variation that the within-household variation. In fact differences between households are due to obesity status, youth, poverty, rural, north and east location which are all associated with higher levels of ultra-processed consumption. Nonetheless, becoming old, obese, or moving does not have a strong impact in UP consumption. Some life events with impact in time constraint, such as having young children, return to labour activity, or becoming single, are associated higher UP consumption. Yet, the main driver for within-household UP consumption reduction are prices. These results suggest that policies aiming at decreasing UP consumption should , on the one hand, focus on specific population groups and, on the other hand, use price reductions as lever for within household change of consumption patterns.
