It seems a healthy economy has a lot of wide circularity .. money circulating is a good thing, a result of a functioning market, tracking the flow of real goods / services. But large corps circulating paper 'self-deals' or debt-swaps seems like a bad thing - a creative accounting practice designed to pump up their stock price/valuation.
How can we _quantify_ the difference ? I guess it would need to match the cash / debt flows against the movement of actual goods and services ??
Not an economist, feel free to weigh in, suggest links.
