I conclude that the trend of decline in earnings quality is due more to changes in the sample of firms than to changes in generally accepted accounting principles (GAAP) or in the earnings quality of previously listed firms.

Specifically, successive cohorts display increasing volatility of both revenues and cash flows, arguably because of high uncertainty about the benefits of intangible investments. Further, successive cohorts display decreasing matching and increasing expense volatility, mainly because of the immediate expensing of intangible investments. The increases in revenue and expense volatilities, in conjunction with the decline in
