Why is Crossnational and Cross-cultural agents such as Henrich Carloff and Willem Leyel important when studying Early Modern expansion?

Scientists often need to make sense of complex systems without knowing the important parameters or even without access to all the information. A collaboration of network theorists, including Diego Garlaschelli (IMT Lucca/Leiden), has now published a review article in the inaugural issue of Nature Reviews…

EuDEco (Modelling the European Data Economy) is a Coordination & Support Action (CSA) receiving funding from the European Union’s Horizon 2020 programme.

Houben and Ten Oever investigate the relationship between public service obligations in EU law (PSOs) and human rights. PSOs served mainly as a correction to free market forces and did not originate from a human rights perspective.

Following the announcement of the second economic aid package by Dutch Ministers Eric Wiebes, Wopke Hoekstra and Wouter Koolmees, Arco Timmermans discussed the content of the government's second economic package on the Dutch radio programme BNR Lobbypanel.

On 20 October 2021 the plenary of the European Economic and Social Committee adopted its opinion on the proposed EU strategy for the Schengen area.

This Think20 (T20) policy brief recommends the introduction of a

In the late 19th and early 20th century, hundreds of thousands of Chinese labor migrants crossed the seas to the Dutch East Indies. On the tobacco plantations of northeastern Sumatra and in the tin mines of Bangka and Belitung, they endured long hours and harsh conditions. Their journeys formed part…

How did changes in the composition and exploitation of princely domains in various principalities of the Low Countries influence the development of ‘modern’ public finance systems, including the notion of public debt?

In the master’s specialisation in Economic and Consumer Psychology, students study the psychological mechanisms that underlie many of our choices and decisions concerning consumption and other economic behaviours.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

One of the most important puzzles in modern astrophysics is the nature of dark matter.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

As chief economist, Bolhuis will conduct research on topical economic issues. Besides this position, he will remain active as a lecturer at the Department of Economics at Leiden Law School.

The Netherlands cannot stop European labour migrants coming here. Nor does The Hague have much influence on the influx of asylum seekers. But experts believe that we should be able to reduce the need for labour migrants by using intelligent economic policies.

Receiving welfare benefits has a major impact on criminal behaviour. This has been demonstrated by Marco Stam, who defended his thesis on 20 January 2022.

Employer organizations have been presented as strong promoters of the liberalization of industrial relations in Europe. This article, in contrast, argues that the preferences of employers vis-à-vis liberalization are heterogeneous and documents how employer organizations in Spain, Italy, and Portugal…

Who had a say in making decisions about the natural world, when, how and to what end? How were rights to natural resources established? How did communities handle environmental crises? And how did dealing with the environment have an impact on the power relations in communities?

The unemployment replacement rate data set, assembled by Olaf Van Vliet & Koen Caminada (version 1, January 2012), provides data on unemployment benefit schemes in 34 welfare states from the 1970s until 2009. The current data set includes all 27 member states of the European Union and 7 non-EU OECD…

Each scientific institute has its own dynamics. The Executive Board is visiting the different institutes to find out what is going on there.
