Matched-Pair Approach

[Fabian Brand]

Currently, I am working on my Master Thesis and I want to investigate whether Socially, Responsible Investment funds outperform its conventional counterpart, and whether this out/underperformance is persistent. In order to correctly do this, I am required to set up a matched pair sample. I want to match all 50 SRI funds with one of my 3.000 conventional mutual funds based on AGE (+-1 year) and Total Net Asset Value (1 standard deviation away). After reading through stata's Starter Manual, many other posts and comments, I still can't find a way to make this happen.

I hope someone in this Forum can help me further, and I would greatly appreciate any input.

Thank you,
Fabian

I doubt anybody can help you until you show example data for both the SRI and control groups. Please show an example that will actually include some potential matches. please use the -dataex- command to do this. If you are running version 15.1 or a fully updated version 14.2, it is already part of your official Stata installation. If not, run -ssc install dataex- to get it. Either way, run -help dataex- to read the simple instructions for using it. -dataex- will save you time; it is easier and quicker than typing out tables. It includes complete information about aspects of the data that are often critical to answering your question but cannot be seen from tabular displays or screenshots. It also makes it possible for those who want to help you to create a faithful representation of your example to try out their code, which in turn makes it more likely that their answer will actually work in your data.



When asking for help with code, always show example data. When showing example data, always use -dataex-.

Thank you for your response. I will work on delivering example data quickly.
