We study the optimal hiring and firing decisions of a firm under two different firing costs regulations: 1) Dual labor markets characterized by high firing costs for workers with seniority above a threshold ("permanent workers") and by low costs for "temporary workers". 2) The Single Labor...

This paper studies children as a risky asset associated to an investment option. Children provide utility but have a stochastic maintenance cost. We obtain several new results relative to models where children are deterministic goods, among which: i) Higher child risks diminish fertility and...

We study the optimal hiring and firing decisions of a firm under two different firing costs regulations: 1) Dual labor markets characterized by high firing costs for workers workers". 2) The Single Labor Contract, a policy proposal to make firing costs increasing in seniority at the job. We...

This paper makes a theoretical and an empirical contribution to the debate on what caused the "global imbalances". On the empirical side, I provide different types of evidence to support that housing demand shocks (shocks to the aggregate marginal rate of substitution between housing and...

In this paper we study a new factor that matters for fertility and consumption decisions: the risks associated with having and raising a child. We analyze a real options model with incomplete markets to explicitly model both children as a risky investment and the parental option to time...

We study the hiring and firing decisions of a firm in a Dual Labor market and in a Single Labor Contract. Under both regulations, to fire before a certain seniority threshold is similar to an American option that gives the right of firing at low costs. However, the value of the option is...

This paper studies the role of housing markets in explaining recent current account dynamics. I document a strong negative correlation, both across and within countries, between housing and current account dynamics. Then, in a quantitative two-country model without exchange rate driven...

We analyze a model of mortgage markets, housing tenure choice, heterogeneous agents, and default with closed form solutions. We uncover new insights which may inspire empirical work, and we ground already-established insights in a series of tractable expressions. Then we study optimal LTV...

This paper surveys the literature that studies the connection between leverage and executive compensation. First, we discuss the dynamics of pay-for-performance compensation and how to measure it. Then we study the theoretical underpinnings of how firm leverage may be related to the compensation...

We analyze the removal of the credit-risk guarantees provided by the government-sponsored enterprises (GSEs) in a model with agents heterogeneous in income and house price risk. We find that wealth inequality increases, driven by higher mortgage spreads and housing rents. Housing holdings become...
