Sleep is a source of energy. This energy is available in limited quantity and individuals must decide when it should be renewed and when it should be consumed. The economics of sleeping and the economics of resource extraction are one and the same. More specifically, utility maximization with...

The paper explores the relationship between religiosity and fertility among Catholics in Spain, thereby answering the question whether the two parallel trends of dramatic drops in fertility and in religiosity are inter-related. It looks at current religiosity as well as exposure to religiosity...

Custody laws governing living arrangements for children following their parents' divorce have changed dramatically since the 1970s. Traditionally, one parent - usually the mother - was assigned sole custody of the child. Today, many divorced parents continue to share parental rights and...

This paper applies the theory of relational contracts to a model in which a couple decides whether to marry or cohabit, how many children to have and subsequently whether to stay together or separate. We make precise the idea that cooperation in a household can be supported by self interest....

The economic theory of fertility choice builds predominantly on the unitary model of the household, in which there is a single household utility function and potential intra-household disagreement is abstracted from. Empirical evidence suggests, however, that many (potential) mothers and fathers...

Since the 1970s almost all states have introduced a form of joint custody after divorce. We analyze the causal effect of these custody law reforms on the incidence of marriage and divorce. Our identification strategy exploits the different timing of reforms across states and the control group of...

Twin births are often used to instrument fertility to address (negative) selection of women into fertility. However recent work shows positive selection of women into twin birth. Thus, while OLS estimates will tend to be downward biased, twin-IV estimates will tend to be upward biased. This is...
