Labor Markets

In this paper, we measure the extent to which subjective and objective evaluations of new teachers in New York City can predict their future impacts on student achievement. Specifically, we examine evaluations of applicants to an alternative certification program, evaluations of new teachers by mentors that work with them during their first year, and evaluations based on student achievement data from their first year of teaching. We use a large sample, relative to prior work, and, unlike other studies (with the exception of John H. Tyler et al.

Prices are typically used as proxies for countries' export quality. I relax this strong assumption by exploiting both price and quantity information to estimate the quality of products exported to the U.S. Higher quality is assigned to products with higher market shares conditional on price. The estimated qualities reveal substantial heterogeneity in product markets' scope for quality differentiation, or their "quality ladders." I use this variation to explain the heterogeneous impact of low-wage competition on U.S. manufacturing employment and output.

In December 2004, the Financial Accounting Standards Board (FASB) mandated the use of a fair value-based measurement attribute to value employee stock options (ESOs) via Financial Accounting Standard (FAS) 123-R. In anticipation of FAS 123-R, between March 2004 and November 2005, several firms accelerated the vesting of ESOs to avoid recognizing existing unvested ESO grants at fair value in future financial statements.

In a recent paper, Ichino and Moretti (2009) present evidence from a large Italian bank that much of the gap in absenteeism between women and men can be explained by absences with a 28-day cycle. These cyclical absences are interpreted as an effect of menstruation which can explain 14% of the gender earnings gap. While the health consequences of menstruation are undeniable, the general importance of menstruation in explaining gender gaps in absenteeism and earnings is unclear.

We find that fixed effects related to the location of firm's headquarters explain variation in broad based option grants after controlling for industry effects and firm characteristics traditionally known to affect option granting. Location matters because of local labor market conditions and social interaction with neighboring firms.

A growing body of research has demonstrated an important relationship between work experience and teacher productivity. This implies that educational quality can be improved through reduction in turnover or acceleration of the return to experience. Mentoring has become an extremely popular policy to achieve these goals, but little is known about its general impact on teachers. I study the impact of mentoring on new teachers in New York City, which adopted a nationally recognized mentoring program in 2004.

We use six years of panel data on students and teachers to evaluate the effectiveness of recently hired teachers in the New York City public schools. On average,the initial certification status of a teacher has small impacts on student test performance. However, among those with the same experience and certification status,there are large and persistent differences in teacher effectiveness. Such evidence suggests that classroom performance during the first two years is a more reliable indicator of a teacher's future effectiveness.

The gap between the qualifications of New York City teachers in high-poverty schools and low-poverty schools has narrowed substantially since 2000. Most of this gap-narrowing resulted from changes in the characteristics of newly hired teachers, and largely has been driven by the virtual elimination of newly hired uncertified teachers coupled with an influx of teachers with strong academic backgrounds in the Teaching Fellows program and Teach for America.

This paper aims to provide a theory of current account adjustment that generalizes the textbook version of the intertemporal approach to current account and places domestic labor market institutions at the center stage. In general, in response to a shock, an economy adjusts through a combination of a change in the composition of goods trade (i.e., intra-temporal trade channel) and a change in the current account (i.e., intertemporal trade channel). The more rigid the labor market, the slower the speed of adjustment of the current account towards its long-run equilibrium.
