What has the author Beardsley Ruml written?

You're likely thinking of Beardsley Ruml (1894-1960), an American economist who was influential in shaping modern economic thinking, particularly in the realm of taxation and fiscal policy. He was not a prolific writer, but his most notable work is:

* "Taxes for Revenue: A Program for the Future" (1940) - In this pamphlet, Ruml proposed the "pay-as-you-go" income tax system, which became a cornerstone of American tax policy. This system shifted the focus from taxing past income to taxing current income, leading to a more stable and predictable tax system.

Ruml was also a key figure in the development of the Federal Reserve Bank and played a significant role in shaping its policies. He wrote numerous articles and essays on economic topics, which were often published in journals like "The American Economic Review."

However, it's important to note that there are several individuals with the surname "Ruml" who might have written works. To be absolutely sure, it's helpful to provide more context, such as:
