In this paper, they are using Canadian debit card dataset. I am not sure where to get such a dataset.
My broad question is what kind of indicator can I use that indicates real-time economic activity of the people? Something that indicates how much people are buying on an hourly basis for an example. I am willing to look at unconventional datasets or willing to scrape information from scratch.
I thought about using Amazon review timestamps for example, but I know want to when people are buying something. Specially over the United States or smaller.
