Economic preferences may be shaped by exposure to sex hormones around birth. Prior studies of economic preferences and numerous other phenotypic characteristics use digit ratios (2D:4D), a purported proxy for prenatal testosterone exposure, whose validity has recently been questioned. We use...

Changes in family size can affect family's wealth distribution and resource allocation. An abrupt increment in the number of family members through twin-birth is detrimental for the family from a psychological and developmental standpoint. We explore this using Chinese family survey data and...

Story telling is part of life, and the retelling of stories is an important form of communication, cultural practice, and message transmission. Insufficient sleep is known to affect relevant cognitive skill areas necessary for story retelling or transmission fidelity. We conducted a...

We present a two-country version of Hansen and Prescott's two-sector long-run growth model, introducing war by letting the countries take land from each other, at the cost of destroying capital and killing people. Because land is an input only in the Malthus sector the transition to a Solow...

A model of fertility choice is studied in which the utility of parents depends on how much they consume, on how many children they have and on the consumption of their children. Hence, parents are altruistic towards their children, but in a more limited sense than in the much discussed dynastic...

Fertility and female labour force participation are no longer negatively correlated in developed countries. Recently, the role of immigration has been put forward as a driving factor among others. Increased immigration affects supply and prices of household services, which are relevant for...

This paper explores how inflows of low-skilled immigrants impact the tradeoffs women face when making joint fertility and labor supply decisions. I find increases in fertility and decreases in labor force participation rates among high-skilled US-born women in cities that have experienced larger...

Die Vereinbarkeit von Beruf und Familie ist seit einiger Zeit eines der wichtigsten familienpolitischen Ziele. Zum einen, weil es Eltern, insbesondere Müttern, erleichtert werden soll, erwerbstätig zu sein. Zum anderen, weil die Hoffnung besteht, dass die Geburtenrate steigt, wenn berufliche...

This paper estimates the effect of having children on labor force participation of mothers in urban Iranian areas. I exploit sex composition of children as an exogenous source of variation in family size to account for endogeneity of fertility. Using information from the Iranian Household Income...

While fertility is positively correlated across generations, the causal effect of children's experience with larger sibships on their own fertility in adulthood is poorly understood. Using the sex composition of the two first-born children as an instrumental variable, we estimate the effect of...
