Speaking in numbers : the effect of reading performance on math performance among immigrants
Isphording, Ingo Eduard; Piopiunik, Marc; … - 2015
This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

High-ability influencers? : the heterogeneous effects of gifted classmates
Balestra, Simone; Sallin, Aurélien; Wolter, Stefan C. - 2020
This paper examines how exposure to students identified as gifted (IQ ≥ 130) affects achievement in secondary school, enrollment in post-compulsory education, and occupational choices. By using student-level administrative data on achievement combined with psychological examination records, we...

Estimating trade policy effects with structural gravity
Piermartini, Roberta; Yotov, Yoto V. - 2016
The objective of this manuscript is to serve as a practical guide for estimations with the structural gravity model. After a brief review of the theoretical foundations, we summarize the main challenges with gravity estimations and we review the solutions to address those challenges. Then, we...

An alternative conditional asymmetry specification for stock returns
Brännäs, Kurt; Nordman, Niklas - 2001
The paper advances the log-generalized gamma distribution as a suitable generator of conditional skewness. Based on the NYSE composite daily returns an asMA-asQGARCH model along with skewness dynamics is estimated. The results indicate a skewness that varies between sizeable negative skewness...

Gravity, distance, and international trade
Baier, Scott L.; Kerr, Amanda; Yotov, Yoto V. - 2017
We review and interpret the main theoretical developments in the gravity literature from its very early, a-theoretical applications to the latest structural contributions. We also discuss challenges and implement methods to estimate empirical gravity equations. We finish with a presentation and...

The variation of gravity within countries (or 15 reasons why gravity should be estimated with domestic trade flows)
Yotov, Yoto - 2021
The gravity equation is the workhorse model for analysis of bilateral trade flows. Despite solid theoretical foundations and clear gains from theory-consistent policy analysis, there are still gaps between gravity theory and empirics. This paper focuses on domestic trade flows, and I argue that...
