What the paper says

In this study, we examine how ordinary taxes and earmarked taxes influence tax pass-through in a market experiment. We hypothesize that tax pass-through is lower for earmarked taxes than for ordinary taxes and that this difference depends on market conditions, specifically the balance between the trade surpluses for sellers and buyers. Our findings confirm that ordinary taxes result in full tax pass-through, whereas earmarked taxes result in less pass-through. Under earmarked taxes, sellers adjust the level of pass-through based on their trade surplus relative to the buyers’ trade surplus. These results underscore the need to distinguish between tax types. The results of our study provide novel insights into the resource allocation effects of different tax types, offering significant implications for policymakers seeking to regulate goods with externalities through taxation.
