I didn't say that. I said that the common argument that tax/tariff increases are always passed along 100% to consumers is transparently false. And contrary to your criticism, the cited paper agrees with my claim (in this case, while my claim is general):
"In CBO’s assessment, foreign exporters will absorb 5 percent of the cost of the tariffs, slightly offsetting the import price increases faced by U.S. importers. In the near term, CBO anticipates, U.S. businesses will absorb 30 percent of the import price increases by reducing their profit margins; the remaining 70 percent will be passed through to consumers by raising prices."
It goes on to say that other businesses, whose costs haven't increased, will raise prices - which is not at all 'passing along costs to consumers' but a different dynamic - and that the combined two dynamics yield the overall consumer impact equal to 95% of tariff costs:
"In addition, U.S. businesses that produce goods that compete with foreign imports will, in CBO’s assessment, increase their prices because of the decline in competition from abroad and the increased demand for tariff-free domestic goods. Those price increases are estimated to fully offset the 30 percent of price increases absorbed by U.S. businesses that import goods, so the net effect of tariffs is to raise U.S. consumer prices by the full portion of the cost of the tariffs borne domestically (95 percent)."
I think the tariffs are a big mistake but the argument I was addressing - if you tax businesses then consumers effectively pay the tax - is widespread disinformation.
