A New York Times book review:

Jan Tinbergen, the first winner of the Nobel in economic science
(Samuelson was the second), was a physicist who introduced the word
“model” to economics in the 1930s. Tinbergen also studied a topic that
few on Wall Street today want to think about, arguing that “a company
would become less productive if the income of the highest-­paid
employee was more than five times the income of the lowest-paid
employee.”

Where did he publish that idea?  Thanks.
