Studying abroad and the effect on international labor market mobility: evidence from the introduction of Erasmus
We investigate the e¤ect of studying abroad on international labor market mobility later in life for German university graduates. As a source of identifying variation, we exploit the introduction and expansion of the ERASMUS student exchange program, which significantly increases a student's probability of studying abroad. Using an Instrument Variable approach we control for unobserved heterogeneity between individuals who studied abroad and those who did not. Our results indicate that student exchange mobility is an important determinant of later international labor market mobility: We find that studying abroad increases an individual's probability of working in a foreign country by about 15 to 20 percentage points, suggesting that study abroad spells are an mportant channel to later outmigration. The results are robust to a number of specification checks

We investigate heterogeneity in returns and find that studying abroad has a stronger effect for credit constrained students. Furthermore, we suggest mechanisms through which the effect of studying abroad may operate. Our results are robust to a number of specification checks.international mobility, migration, student exchange, education

Comment on "Probing the equilibrium dynamics of colloidal hard spheres above the mode-coupling glass transition"
In the Letter [PRL 102, 085703 (2009)] Brambilla, et al. claimed to observe
activated dynamics in colloidal hard spheres above the critical packing
fraction of mode coupling theory (MCT). By performing microscopic MCT
calculations, we show that polydispersity in their system shifts the critical
packing fraction above the value determined by van Megen et al. for less
polydisperse samples, and that the data agree with theory except for, possibly,
the highest packing fraction.Comment: Comment in print in Phys. Rev. Lett.; for accompanying reply see

Overshoots in stress strain curves: Colloid experiments and schematic mode coupling theory
The stress versus strain curves in dense colloidal dispersions under start-up
shear flow are investigated combining experiments on model core-shell
microgels, computer simulations of hard disk mixtures, and mode coupling
theory. In dense fluid and glassy states, the transient stresses exhibit first
a linear increase with the accumulated strain, then a maximum ('stress
overshoot') for strain values around 5%, before finally approaching the
stationary value, which makes up the flow curve. These phenomena arise in
well-equilibrated systems and for homogeneous flows, indicating that they are
generic phenomena of the shear-driven transient structural relaxation.
Microscopic mode coupling theory (generalized to flowing states by integration
through the transients) derives them from the transient stress correlations,
which first exhibit a plateau (corresponding to the solid-like elastic shear
modulus) at intermediate times, and then negative stress correlations during
the final decay. We introduce and validate a schematic model within mode
coupling theory which captures all of these phenomena and handily can be used
to jointly analyse linear and large-amplitude moduli, flow curves, and
stress-strain curves. This is done by introducing a new strain- and
time-dependent vertex into the relation between the the generalized shear
modulus and the transient density correlator.Comment: 21 pages, 13 figure
