Valuation Calculator for Subscription-Based Businesses

Last summer I worked on a project that used Daniel McCarthy, Peter Fader and Bruce Hardie’s valuation model, described in their paper “Valuing Subscription-Based Businesses Using Publicly Disclosed Customer Data” available at SSRN.

The future of economic publishing

I finished my thesis on Financial Economics at the beginning of this summer. I performed simulations for different investment strategies for Turkish households, to see which investment option is the best.

Why don't more economists get hired as data analysts?

Simulating Likert scale data in R

In my last project I had to find theoretical limits for a psychometric index involving Likert scale data (aka categorical data). After successfully finding it, I decided to test the results in a simple Monte-Carlo simulation.

Object-oriented Game of Life in Python

Intro

I have been planning to build a superior GUI alternative to NetLogo for a long time. When I finally started working on a project, I decided to test the basic implementations in Python. Sure enough, the first app was Conway’s Game of Life - a great special case of cellular automata.

Bitcoin forgot its roots. Should we tax it?

Bitcoin was invented and became popular first within a crypto community whose members were predominantly influenced by the so-called “hacker culture”.

This is how you should never end your blog posts

Almost every blogging tutorial suggests you to end your posts with the so-called CTAs (call-to-action). They say that encouraging your readers to comment will help to promote your blog. Most bloggers seem to miss the point and use phrases like “and what do you think?”, “share your thoughts in comments”. For sure, commenting increases indexation of your page and solidifies your audience, but this only happens if comments come organically. I will now elaborate on my claim.

Business education needs a dose of pessimism

Undergraduate business education faces a lot of criticism spanning from lack of practical training to philosophical arguments that management shouldn’t be taught at undergraduate level at all. I cannot change the status quo and won’t try to repeat these statements - I will try to give a constructive feedback. What I propose in this article is very easy to implement: it will just require change in the attitude.

Introducing Panel FMOLS/DOLS command for Stata

Last week I was hired to perform a thorough analysis of a panel dataset for export dynamics of different sectors in a country. I had never done panel econometrics before or even read it in a textbook. But since I am good at cross-section and time-series, I believed I could handle the task. And I wasn’t wrong.

Why is econometrics focused on linear models?

Econometrics is a separate discipline from statistics/probability/machine learning for a reason. The primary aim of econometrics and economics in general is interpretability. Economists could easily build very realistic models with hundreds of moving parts/variables, but they don’t do it, because they aim to make models as simple as possible.

Using impulse response functions to interpret partial effects in neural networks

This week I’ve been working on a research paper based on a very simple idea which, hopefully, can solve an important problem in applying machine learning techniques in economics — the interpretability. So, if you recall, the neural networks is the generalization of a logit model where sigmoid of a linear combination of inputs is used iteratively.

Undergraduate business degree is a waste of time

I believe that undergraduate business education is the most useless degree. Having received one myself, I can tell you that every single topic they teach can easily be learned by reading a textbook or googling.

Transform Excel into a translation tool using this VBA macro

A brief preface

This summer I did an internship at BSH Hausgeräte (aka Bosch and Siemens Home Appliances), where I built a lot of amazing tools on Excel using VBA (Visual Basic for Applications). I helped them automate monthly reports, which now take just a few seconds to complete. I would’ve contribute a lot more to the company if not for the corporate restrictions, according to which I wasn’t authorized to access code from other departments.
