As U.S. corporate profit margins have made it to record highs, a debate has raged between those who place their hopes on a new paradigm of sustained high profits and those who believe in capitalism’s efficiency and the tendency of margins to revert to the mean. Using a bottoms-up analysis framework, we show that an often-cited explanation for the new paradigm – that the U.S. economy is more service-focused – lacks empirical support. Our analysis rejects the hypotheses that higher profit margins are a result of technological progress or increased efficiency. Instead, we show that much of profit margin improvements are related to increased focus on improving earnings in the short-term.
