比DID更加灵活的DDID政策效应评估方法
今天给圈友推荐一个比DID更加灵活的DDID命令，这对于处理政策效应更加弹性，毕竟它允许这个放进来的政策虚拟变量出现lags或forwards。在面板数据中，一个个体在不同时间点可以是处理组或对照组，过去的政策影响现在或将来可能的政策影响现在，这样当然就比DID灵活很多。

写在后面：各位圈友，咱们的计量经济圈社群里面资料和计量咨询都很多，希望大家能够积极加入咱们这个大家庭（戳这里）。之后我们会逐步邀请社群里的圈友再直接建立微信群与圈圈对话，进去之后一定要看“群公告”，不然接收不了群信息。
I was born in 1973. I took a degree in Statistics and Economics at Sapienza University of Rome in 1998, and a PhD in Economics at the same university in 2003. Given my statistical background, I am interested in analyses based on econometric and statistical tools. My research interest is in “applied economics and econometrics”, with a special focus on both the theoretical and applied "econometrics of program evaluation", and on the "economics of R&D and innovation”. I developed some original models for quantitative program evaluation, such as models for continuous treatment, neighborhood interaction, as well as nonparametric extensions of previous models. In applications, my research activity focuses mainly on measuring quantitatively the effects of technological policies on firm economic and technological performance.
My contribution within the econometrics of program evaluation is also computational, as I performed several Stata routines for implementing some program evaluation techniques.
My second related research area is on agent-based simulation models. Indeed, I have been working on the role played by (bounded) rationality and coordination in modeling economic behaviors since my degree thesis. Part of my two-year post-doc experience at the IUAV (University of Venice) touched strongly on the (problematic) relation between mathematics and economics modeling. From a theoretical perspective, I am sympathetic with evolutionary theorizing, although I make use of what I feel to be compelling also in mainstream theory. I am also interested in economic methodology.
According to RePEc (Research Papers in Economics) archive, I am among the top 5% authors according to these criteria:
Number of Abstract Views in RePEc Services over the past 12 months
Number of Downloads through RePEc Services over the past 12 months
Number of Abstract Views in RePEc Services over the past 12 months, Weighted by Number of Authors
Number of Downloads through RePEc Services over the past 12 months, Weighted by Number of Authors
I am Editor-in-Chief of the International Journal of Computational Economics and Econometrics.
I am Associate Editor of the World Review of Science, Technology and Sustainable Development.
I am coordinator of GRAPE - Research Group on the Analysis of Economic Policies.
I am author of the book: Econometric Evaluation of Socio-Economic Programs: Theory and Applications.
Last but not least, “social economics” is another other field of inquiry I worked on. In my PhD thesis, in fact, I built a Social Accounting Matrix for the Italian welfare-mix system and performed simulations to see what a role an emerging non-profit sector can play.
I deem economics to be a social science, where the term “social” deals primarily with our moral responsibility toward mankind and our planet.
