This is a Supplemental online Appendix, containing additional theoretical and empirical results. 1 Supplemental Online Appendix Here we provide additional supplemental material. First is some details regarding extensions to higher order derivatives and larger than marginal changes in the threshold. Next is a second empirical application, showing application of our methods in a fuzzy design cont...

A new modification of the Method of Lines is proposed for the solution of first order partial differential equations. The accuracy of the method is shown with the matrix analysis. The method is applied to a number of test problems, on uniform grids, to compare the accuracy and computational efficiency with the standard method.

Regression discontinuity models, where the probability of treatment jumps discretely when a running variable crosses a threshold, are commonly used to nonparametrically identify and estimate a local average treatment effect. We show that the derivative of this treatment effect with respect to the running variable is nonparametrically identified and easily estimated. Then, given a local policy i...

We evaluate a “girl-friendly” primary school program in Burkina Faso using a regression discontinuity design. After 2.5 years, the program increased enrollment by 19 percentage points and increased test scores by 0.41 standard deviations. For those caused to attend school, scores increased by 2.2 standard deviations. Girls’ enrollment increased by 5 percentage points more than boys’ enrollment,...

This paper attempts to understand the structure underlining the weakness of the Indonesian economic development strategy in a systemic perspective. The explanation assumes the importance of industrial technological capability within the framework of the techno-economic structure. The results of a simulated model of techno-economic administration show the weakness of the industrial technological...

Recent results for tree amplitudes for the N = 2 noncritical strings are presented and compared with the critical case. Arguments are given which indicate a certain discontinuity in passing from thê c < 1 model (in a Coulomb gas representation) to thê c = 1 critical case.
