R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth ("strong scale effect") or the level of per capita income ("weak scale effect"), with far-reaching policy implications. However, for modern times there is little empirical support...

We provide the first measurement of knowledge spillovers from venture capital-financed companies onto the patenting activities of other companies. On average, these spillovers are nine times larger than those generated by the R&D investment of established companies. Spillover effects are larger...

How have house prices evolved over the long-run? This paper presents annual house prices for 14 advanced economies since 1870. Based on extensive data collection, we show that real house prices stayed constant from the 19th to the mid-20th century, but rose strongly during the second half of the...

When searching for productivity spillovers from foreign firms, a firm is typically classified as foreign using a low threshold of direct foreign ownership. Instead, we advocate an ‘ultimate owner' definition because (i) ultimate ownership includes indirect ownership links that are prevalent in...

This paper develops a two-sector R&D-based growth model with congestion effects from increasing urban population density. We show that endogenous technological progress causes structural change if there are positive productivity spillovers from the modern to the traditional sector and Engel's...
