Reactance: a Freedom-Based Theory of Choice
Prohibitions create the desire they were intended to cure'' (Lawrence Durell). This phenomenon -- often referred to as reactance -- has been recognized for decades by psychologists. Despite numerous economic implications, no theoretical model has been proposed yet. This paper develops axiomatically a revealed preference approach of menu-dependent choices triggered by reactance. The choice model relies on four components: a complete and transitive utilitarian preference; a partition of alternatives into distinct types; a reference set, composed of the alternatives the decision-maker feels entitled to have access to; and a menu-dependent offset function that triggers reactance. The Weak Axiom of Revealed Preference is suitably relaxed. Building on four additional axioms, our representation theorems obtain endogenously the four components along with a uniqueness result. We derive from our representation a preference over menus and argue that our model can be seen as a choice theory counterpart of the freedom of choice literature. Finally, we discuss several applications.

Wage Progression, Human Capital and Welfare Reform
In this paper we develop a panel data model to examine why the wages of lower educated workers show slower growth over the life-cycle relative to those for the higher educated and investigate role of human capital investments during working life, both learning-by-doing and on-the-job training. Using this framework, we analyse how human capital investments (and children) impact on female earnings and how allowing for human capital changes the way we evaluate (and design) welfare-to-work and tax-credit policies, especially those policies designed to encourage mothers into work. Finally, we take a look at the role of firms and technology and consider what attributes among the lower educated are more likely to generate returns to work experience and wage progression.
