If you're selling a digital product* to a global audience, you are missing out on customers because their purchasing power doesn't go as far as yours.
For example, you've self-published a novel--congratulations!--and you've priced it at USD $20. For someone in the USA, that might be a reasonable expense, but for your readers in, say, Brazil, that might make a big dent in their budget.
Wouldn't it be great if you could price your novel so that it costs your international readers about the same, in real terms, as your readers in the US?
That's what we're trying to achieve here with Purchasing Power Parity.
* You can definitely calculate PPP for a physical product, but digital products are easier to reason about because the cost of production and distribution is, presumably, the same--you don't have to worry about shipping costs, import taxes, the cost of materials in different locales, etc.
Check out the documentation for an example of how you can create a coupon to give your international purchasers a discount.
Add this line to your application's Gemfile:
gem 'ppp'And then execute:
$ bundle
Or install it yourself as:
$ gem install ppp

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
First, be kind. Please approach this library with the assumtion that I am working in good faith and doing my best with the knowledge that I have. I would love suggestions and input from people who know more about economics than I do, but please do so without calling me a moron 🙂.
