Abstract : European fascist regimes have attached great importance to nationalistic families and designed policies to perpetuate them. Most offered policy packages with interest-free loans repayable through childbirth, along with allowances and tax deductions for large families. Using a difference-indifference approach and Nazi Germany as a case study, we show that these policies may have counterproductive effects due to negative selection mechanisms in the marriage market. The excessive pressure to marry exerted on singles results in lower quality, ultimately less fertile, and more fragile unions. This finding is important as the main European far-right parties today propose reinstating these policy packages.

"Random choice with status quo bias"

Eric Danan, en collaboration avec Tigran Melkonyan et Zvi Safra

Lemma - 4 rue Blaise Desgoffe, 75006 Paris. Salle Maurice Desplas

Abstract : This is an ongoing work aiming to introduce status quo bias (and subsequently other types of framings or nudges) into random choice models. Existing models of status quo bias (e.g. Masatlioglu and Ok, 2005; 2013) are cast in a deterministic choice framework and, consequently, the status quo often has an extreme effect on choice. Adopting a random choice setting therefore seems more plausible. We thus introduce status quo options in the random expected utility model of Gul and Pesendorfer (2006), define and axiomatize a representation where the status quo affects choice probabilities through utility penalties.
