Functional form and the estimated effects of school resources
نویسنده
چکیده
A widely-cited result in the education production function literature is that the level of measured school inputs (e.g., student–teacher ratio or starting teacher salary) is not associated with differences in student achievement, all else equal. I argue that this result may be attributable in part to the restrictive functional form assumptions used in the existing literature. I use detailed national student-level data to estimate an education production function that does not employ the restrictive assumptions of homotheticity and additivity and find statistically significant evidence that school inputs are associated with student performance. Moreover, I find evidence that traditional education production functions may understate the magnitude of the effects of school factors on student achievement. However, I find that even these larger estimated effects of measured school inputs are very small. [JEL I21] 1999 Published by Elsevier Science Ltd. All rights reserved.

Plant Species and Functional Types’ Diversity in Relation to Grazing in Arid and Semi-arid Rangelands, Khabr National Park, Iran
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
