Estimating the Skill Bias in Agglomeration Externalities and Social Returns to Education:Evidence from Dutch Matched Worker-Firm Micro-Data

This paper employs a unique set of micro-data covering almost one-third of the Dutch labor force, to estimate the heterogeneity of agglomeration externalities across education levels. This paper shows that there is substantial heterogeneity in the relationship between agglomeration and productivity of workers (proxied by their hourly wage) with different educational background. Apart from estimating the impact of the aggregate density of regional labor markets, we also estimate whether the composition of the local labor market in terms of education is related to the productivity of different types of workers. Using the presence of universities as an instrument, we estimate the effect of the supply of university graduates on wages, i.e. the social return to education. We find that agglomeration externalities are substantially higher for high- and medium skilled than for low-skilled employees. We find no positive effects from the presence of high-skilled on the productivity of low-skilled

The Transaction Costs Perspective on Standards as a Source of Trade and Productivity Growth

This paper discusses the design, implementation and use of standards from the perspective of transaction costs economics. A proper design and implementation of standards may lead to a considerable reduction of transaction costs, which enhances trade and, consequently, economic welfare. A major example is the use of containers, which has drastically changed the worldwide transport infrastructure, and lowered the costs of transport of goods considerably. The example of containers also shows that network externalities play a major role in the use of standards, and that, on the other hand, worldwide standards with large sunk investment costs may lead to a lock-in. This may call for government intervention in the design and use of standards, and in the transition processes to new standards. The paper provides ample further examples of standards and on the role of the government, or clubs, with respect to these standards

Financial incentives for mortgage prepayment behavior:Evidence from Dutch micro data

This paper exploits a unique set of Dutch micro data between 2006 and 2014 to analyze the heterogeneous responses in prepayment behavior to changes in financial incentives. Prepayment is defined as paying back a part of the mortgage on top of the contractual payment schedule, excluding refinancing. Because interest rates on savings have decreased while the rates on existing mortgages are generally fixed for some years, the value of prepaying a mortgage has increased. This corresponds with the surge in prepayments at the Dutch mortgage market. Using various econometric specifications, that take into account unobserved heterogeneity and endogeneity, the paper finds that incentives to prepay explain only a part of prepayment behavior. However, incentives to prepay explain a much larger part of prepayments for wealthier households and for households with a high net-of-tax interest rate differential

Economisch perspectief voor een grondige renovatie van de woningmarkt

De Nederlandse woningmarkt is slecht toegankelijk, creëert vermogensongelijkheid en is grillig. Dat laatste is schadelijk voor onze economie. Bovendien is het huidige woonbeleid duur. Een grondige renovatie van het woonbeleid biedt een structurele oplossing

Rare and low-frequency coding variants alter human adult height

Height is a highly heritable, classic polygenic trait with approximately 700 common associated variants identified through genome-wide association studies so far. Here, we report 83 height-associated coding variants with lower minor-allele frequencies (in the range of 0.1-4.8%) and effects of up to 2 centimetres per allele (such as those in IHH, STC2, AR and CRISPLD2), greater than ten times the average effect of common variants. In functional follow-up studies, rare height-increasing alleles of STC2 (giving an increase of 1-2 centimetres per allele) compromised proteolytic inhibition of PAPP-A and increased cleavage of

Transverse momentum spectra of charged particles in proton–proton collisions at √s=900 GeV with ALICE at the LHC

The inclusive charged particle transverse momentum distribution is measured in proton–proton collisions at s=900 GeV at the LHC using the ALICE detector. The measurement is performed in the central pseudorapidity region (|η|<0.8) over the transverse momentum range 0.15<pT<10 GeV/c. The correlation between transverse momentum and particle multiplicity is also studied. Results are presented for inelastic (INEL) and non-single-diffractive (NSD) events. The average transverse momentum for |η|<0.8 is 〈pT〉INEL=0.483±0.001 (stat.)±0.007 (syst.) GeV/c and 〈pT〉NSD=0.489±0.001 (stat.)±0.007 (syst.) GeV/c, respectively. The data exhibit a slightly larger 〈pT〉 than measurements in wider pseudorapidity intervals. The results are compared to simulations with the Monte Carlo event generators PYTHIA and PHOJET
