Investment in skills, managerial quality and economic development (PDF)
Abstract: I document that for a group of 38 countries ranging from low to high income: (1) the share of skilled managers is higher in richer countries, (2) the relative income of managers to non-managers is lower in richer countries, and (3) the relative income of skilled to unskilled individuals is lower in richer countries. In addition, the share of managers is lower in richer countries while the mean plant size is larger in richer countries. I explore these facts through the lens of a general equilibrium model of investment in skills and occupational choice. Countries differ in productivity level in production and the level of size-dependent distortions. I find that exogenous productivity differences alone can produce the above facts qualitatively, but size-dependent distortions are needed to account for these facts quantitatively and the output elasticity of productivity is 2.6.

2016- Teaching Mathematics in Seven Countries, 1st Edition. Meraat Educational Innovations Center, Tehran, Iran. (joint with Moharram Naghizadeh and Masoud HajiSeyedHosseiniFard)
This is a translation of a report by the National Center for Education Statistics , from English to Persian. The report is part of the TIMSS 1999 Video Study and consists of video lectures from 8th-grade mathematics classes, which was recorded in 1999, to study best practices in teaching mathematics. The countries in the study are Australia, the Czech Republic, Hong Kong SAR, Japan, the Netherlands, and Switzerland. The statistical analysis in the book provides seven teaching signatures in teaching mathematics and the videos provide actual practices of different teaching signatures. All the video lectures are subtitled in Persian. This book is used as a textbook in official educational degrees for teaching high school mathematics in universities in Iran.
