Parey Matthias (2020) International Student Mobility Programs,In: The SAGE Encyclopedia of Higher Education SAGE Publications

This entry discusses programs that support, encourage or administer International Student Mobility (ISM). According to the definition from the Higher Education Funding Council for England (HEFCE, 2004), ISM is ?any form of international mobility which takes place within a student?s programme of study in higher education?. ISM programs can refer to supporting outbound students (outward mobility) as well as incoming students from abroad (inward mobility). Students planning a spell abroad can either plan and organize their stay independently (as what are called free movers) or via a student exchange program.

This entry begins by providing an overview of patterns of student mobility, and then describes the role of student mobility programs. ISM includes both short-term study abroad visits as well as long-term study abroad stays for entire degree programs. This entry emphasizes study abroad as a part of a student?s higher education studies (often referred to as credit mobility), rather than completing an entire degree program abroad (degree mobility). In the following, the challenges of evaluating the effect of study abroad programs on subsequent outcomes are discussed. The introduction of the ERASMUS program is considered in light of research that has been undertaken using the launch and growth of the program as opportunities to examine and understand the effects of study abroad participation. The entry discusses the role of student exchanges on subsequent international mobility choices, as well as on subsequent labor market outcomes. It concludes by addressing some key open questions in this area.

Fu Jia-Young (Michael), Horowitz Joel L., Parey Matthias (2020) Testing Exogeneity in Nonparametric Instrumental Variables Models Identified by Conditional Quantile Restrictions,Econometrics Journal Oxford University Press
This paper presents a test for exogeneity of explanatory variables in a nonparametric instrumental variables (IV) model whose structural function is identified through a conditional quantile restriction. Quantile regression models are increasingly important in applied econometrics. As with mean-regression models, an erroneous assumption that the explanatory variables in a quantile regression model are exogenous can lead to highly misleading results. In addition, a test of exogeneity based on an incorrectly specified parametric model can produce misleading results. This paper presents a test of exogeneity that does not assume the structural function belongs to a known finite-dimensional parametric family and does not require estimation of this function. The latter property is important because nonparametric estimates of the structural function are unavoidably imprecise. The test presented here is consistent whenever the structural function differs from the conditional quantile function on a set of non-zero probability. The test has non-trivial power uniformly over a large class of structural functions that differ from the conditional quantile function by O(n?1/2)`. The results of Monte Carlo experiments and an empirical application illustrate the performance of the test.
Chakravarty Abhishek, Parey Matthias, Wright Greg C. (2020) The Human Capital Legacy Of A Trade Embargo,Journal of the European Economic Association Oxford University Press (OUP)
We estimate the effects of in-utero exposure to a trade embargo on survival and
human capital in an import-dependent developing country. Using a regression discontinuity
design, we find that a nearly comprehensive embargo imposed by India
on Nepal in 1989 led to a large decline in reported live births, and increased early
life mortality. The decline in births is concentrated in poorer, more remote districts,
and is sharper for female births than male births, consistent with documented gender
discrimination. Women survivors of exposure are more educated in adulthood
than unexposed cohorts.
