A new measure of quality of life explains why people like living in bigger cities

People like to live in certain places, even when higher wages are on offer elsewhere. Gabriel Ahlfeldt, Fabian Bald, Duncan Roth and Tobias Seidel show that once you take into account people's preferences, large cities o...Read more...

Measuring quality of life under spatial frictions

Using a quantitative spatial model as a data-generating process, we explore how spatial frictions affect the measurement of quality of life. We find that under a canonical parameterization, mobility frictions - generated...Read more...

Why higher house prices lead to higher borrowing

In the past three decades, house prices and mortgage debt in the UK have risen much faster than income. In other words, people end up borrowing more money when house prices go up. This finding goes against many canonical...Read more...

Housing-consumption channel of mortgage demand

We quantify the housing-consumption channel in mortgage demand according to which households borrow more following house-price increases since housing and non-housing consumption are imperfect substitutes. To identify th...Read more...

A micro-geographic house price index for England and Wales

We generate a mix-adjusted house price index for England and Wales from 2010 to 2020 at the level of lower-layer super output areas. To this end, we blend parametric and non-parametric estimation techniques and leverage ...Read more...

The skyscraper revolution: Global economic development and land savings

The economics of skyscrapers: a synthesis

We document that skyscraper growth since the end of the 19th century has been driven by a reduction in the cost of height, increasing urbanization, and rising incomes. These stylized facts guide us in developing a compet...Read more...
