"Pomperipossa in Monismania", also called "Pomperipossa in the World of Money", is a satirical story written by the Swedish children's book author Astrid Lindgren in response to the 102% marginal tax rate that she incurred in 1976. It was published starting on 3 March in the Stockholm evening tabloid Expressen and created a major debate about the Swedish tax system. The marginal tax rate above 100%, dubbed the "Pomperipossa effect", was due to tax legislation that required self-employed individuals to pay both regular income tax and employer's fees. Pomperipossa in Monismania was translated into English by Sarah Death and was published in the first issue of the magazine Swedish Book Review in 2002.
