We describe a rational expectations model in which speculative bubbles in house prices can emerge. Within this model both speculators and their lenders use interest-only mortgages (IOs) rather than traditional mortgages when there is a bubble. Absent a bubble, there is no tendency for IOs to be...

The authors construct a dynamic general equilibrium model of cities and use it to estimate the effect of local agglomeration on per capita consumption growth. Agglomeration affects growth through the density of economic activity: higher production per unit of land raises local productivity....

Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practise local population changes are dominated by variation in net migration, and we argue that understanding gross migration is essential to quantify how net migration may slow population...

This paper empirically investigates whether emigrants from MENA countries self-select on cultural traits such as religiosity and gender-egalitarian attitudes. To do so, we use Gallup World Poll data on individual opinions and beliefs, migration aspirations, short-run migration plans, and...

A body of evidence has emerged in the literature on intergenerational mobility documenting that countries with large income differences also have less intergenerational mobility: a relationship known as the Great Gatsby Curve. In this paper, I estimate the Great Gatsby Curve within Sweden...

The Recruitment grant was a student aid policy that replaced the loans in the student aid system with grants for unemployed adults with low education. In this paper, I estimate the causal effects of repealing this policy on the educational attainment and subsequent labor market outcomes for the...

This paper explores a new approach to identifying government spending shocks which avoids many of the shortcomings of existing approaches. The new approach is to identify government spending shocks with statistical innovations to the accumulated excess returns of large US military contractors....

We document that home ownership of households with 'heads' aged 25-44 years fell substantially between 1980 and 2000 and recovered only partially during the 2001-2005 housing boom. The 1980-2000 decline in young home ownership occurred as improvements in mortgage opportunities seemingly made it...

This comment explains why the findings presented in Beaudry and Lucke (2009) are misleading.

After three decades of being relatively constant, the homeownership rate increased over the 1994-2005 period to attain record highs. The objective of this paper is to account for the observed boom in ownership by examining the role played by changes in demographic factors and innovations in the...
