I thank Claire Black and Wei-Jang Huang for assistance in preparing this paper. I appreciate the comments of George Erickcek on a preliminary version of this paper. This paper was previously presented on November 20, 2009 at the 57th Annual Economic Outlook Conference of the Research Seminar in Quantitative Economics (RSQE) at the University of Michigan. I appreciate comments and questions for ...

Regional Economic Growth and Human Capital: The Role of Overeducation The paper analyses the link between human capital and regional economic growth in the European Union. Using various indicators of human capital calculated from census microdata, we conclude that the recent economic performance of European regions is associated with an increase in overeducation. In fact, measures of educationa...

This paper combines individual-level data from the German Socio-Economic Panel (SOEP) with economic and demographic postcode-level data from administrative records to analyze the eff ects of immigration on wages and unemployment probabilities of highand low-skilled natives. Employing an instrumental variable strategy and utilizing the variation in the population share of foreigners across regio...

This study uses a boundary design and propensity score methods to the effects of 1930s-era Home Owners Loan Corporation (HOLC) “redlining” maps on long-run trajectories urban neighborhoods. The led reduced home ownership rates, house values, rents increased racial segregation in later decades. A comparison either side city-level population cutoff that determined whether were drawn finds broadly...

Among ‘empirical’ methods of estimating oxygen abundances in extragalactic H ii regions, the use of the ratio of nebular lines of [O iii] and [N ii], first introduced by Alloin et al. in 1979, is reappraised with modern calibration data and shown to have certain advantages over R23 ≡ ([O ii] + [O iii])/Hβ and N2 ≡ [N ii] λ6583/Hα, particularly when applied to star-forming galaxies at high redsh...

For studies of galaxy formation and evolution, one the major benefits James Webb Space Telescope is that space-based IFUs like those on its NIRSpec MIRI instruments will enable spatially resolved spectroscopy distant galaxies, including at scale individual star-forming regions in galaxies have been gravitationally lensed. In meantime, there only a very small subset lensed sources where work thi...

ABSTRACT We derived a bi-dimensional calibration between the emission-line ratios $R_{23}= ([\mathrm{ O}\, {\small {\rm II}}]\,\lambda 3726 +\lambda 3729 +[\mathrm{ O}\mathrm{ }\, III}}]\,\lambda 4959 + \lambda 5007)/\rm H\,\beta$, ${\it P}=[([\mathrm{ 4959+\lambda 5007)/{\rm H}\,\beta ]/R_{23}$ and oxygen abundance relative to hydrogen (O/H) in gas phase of Seyfert 1 2 nuclei. In view this, in...

In this paper, I document that workers in larger cities have significantly more occupational options than smaller ones. They are able to form better matches and earn higher wages. also note differences occupation reallocation patterns across cities. develop a dynamic model of choice microfounds agglomeration economies captures the empirical patterns. The calibration suggests match quality accou...

This paper examines race and police use of force using data on 1.6 million 911 calls in two cities, neither which allows for discretion officer dispatch. Results indicate White officers increase much more than minority when dispatched to neighborhoods. Estimates Black (Hispanic) civilians are 55 (75) percent likely experience any force, five times as a shooting, compared if scaled up similarly ...
