Should we densify or relocate cities?
As part of his PhD on the spatial distributional effects of the climate transition, Yashvant Premchand, together with Peter Mulder, mapped out the costs and benefits of housing construction in climate-risked areas.

Read MoreNew research: Which house price data are suitable for housing market research?
Which house price data can researchers use? Ideally, one would use sales prices: the prices at which houses were actually sold. In practice, however, this data isn’t always available, or it only becomes available with a delay.

Read MoreHigh-speed rail and the spatial economy
High-speed rail (HSR) is expanding rapidly and is often promoted as a fast and sustainable mode of transport. A recently published article by Hans Koster and Jacques Thisse reviews a large body of theory and empirical evidence and shows that, while HSR can deliver substantial aggregate benefits, it also reshapes residential and employment patterns. These spatial reallocations…

An increasing number of developing countries are restricting non-renewable natural resource exports to encourage domestic processing, move up the global value chain, and spur local development. Maarten Bosker, Else-Marie van den Herik, Paul Pelzl, and Steven Poelhekke study the local labour-market effects of Indonesia’s voluntary export ban on unprocessed nickel and bauxite in 2014, previously…

On 27 November 2025, Mark Thissen delivered his inaugural lecture. In his lecture, titled ‘Macht en fragmentatie in regionale productieketens: van just-in-time naar just-in-case’ (Power and Fragmentation in Regional Production Chains: From Just-in-Time to Just-in-Case) he argued that political and economic changes around the world are increasing the importance of region-specific policies – and, consequently,…

NV Zeedijk was founded in the 1980s to revitalize the then-deteriorated Zeedijk area in Amsterdam. By strategically purchasing, renovating, and actively managing properties, the organization – with the Municipality of Amsterdam as its largest shareholder –…

Recent research by Jan Rouwendal, Or Levkovich, Edwin Buitelaar and Jip Claassens, published in Regional Science and Urban Economics, shows that the prices of older commercial buildings increase relative to younger ones. According to the researchers, this is the result of the so-called “vintage effect”: in a growing real estate market, older buildings turn out to…
