Taxes and Trade: A Pacific Island Shift

From 2010 to 2021, a bunch of Pacific Island countries saw changes in their taxes. We looked at how less trade rules affected tax money from trade. As these islands got more open to trade, they collected less money from trade taxes and direct income taxes. Interestingly, they started collecting more from domestic indirect taxes. Why? Well, open trade might bring more business, but it also means less control over imports and exports, which are what trade taxes usually target. There's also something called the Laffer effect. It's like a curve showing that too much tax can actually bring less money. Think of it like squeezing a lemon—squeeze too hard, and you get less juice. Our findings hint at this for trade tax revenues. Regional trade agreements? They seemed to help trade tax revenues. But here's a twist: more public debt from other countries actually boosted total tax revenues. And foreign aid? It's linked to a drop in both total and trade tax revenues. Maybe aid can sometimes create dependence, making countries rely less on their own taxes.
