Industry Spotlight: Tariffs
Tariffs are taxes on imported goods. Historically, their value has been controversial. Observationally, they tend to produce unintended consequences.
As to who pays the tariff, it could be the importer of the good or service or it could be us, the consumers of said goods or services. This is dependent on the pricing power of the importer. In most cases, historically, tariffs are paid by the consumer. Tariffs are not paid by the producer.
To the extent that the importer can source a given product or service from another provider and country, then the tariff may hurt the target country/producer. However, if there are tariffs on all imported goods, then the consumer is almost certainly going to see increased prices (or the importer will face decreased profitability and cashflow) until such time as the goods or services can be insourced. Prior pricing (and/or profitability and cashflow) are going to be attained only if the insourcing results in a similar cost as the (pre-tariff) imported item. This may, of course, take some time, or it may not be reasonably achievable.
The net result, in most cases, is an increase in cost to the end consumer.
