The views

What is a view?

Our reading of what a group of claims have in common, one level above a korrent: a korrent is our reading of what somebody said, a view is our reading of what several korrents share. The claims are printed under it, so the sentence can be checked against them.

Nobody is filed under a view — claims are. A person is named here because a dated claim of theirs sits under it, and somebody whose claims sit under two views appears under both.

The 2025 American tariffs did not reduce the trade deficit they were imposed to reduce.

The tariffs did not revive American manufacturing; employment in it fell after they were imposed.

Tariff revenue is real but far too small to make a dent in the American deficit.

  1. Paul Krugman Trade economist, Nobel laureate in 2008 for his work… Revenue from the Trump tariffs, even pre-Court, wasn’t enough to make a large dent in the deficit. Attack of the Zombie Tariffspaulkrugman.substack.com · 24 Feb 2026All korrents from this piece
    Revenue from the Trump tariffs, even pre-Court, wasn’t enough to make a large dent in the deficit.

The tariffs survived the case for them because their real purpose was the personal power they conferred.

The American trade deficit is foreigners choosing to invest in America, not America being cheated.

  1. John H. Cochrane Economist at the Hoover Institution this story tells us how an increase in foreign demand to save in the US rather than at home will push up the dollar, and cause the trade deficit, which is in effect how foreigners send us factories which they would rather build here than in their own countries.

America borrowed cheaply from the world and spent it on consumption rather than investment, exactly as Greece did.

  1. John H. Cochrane Economist at the Hoover Institution In sum, spurred on by the federal government (in many ways), the US borrowed a huge amount from foreigners at very low rates, and went on a consumption binge. Sooner or later we have to pay it back, or we go though the wrenching adjustment of a debt crisis. Tariffs, saving, and investmentgrumpy-economist.com · 14 Apr 2025All korrents from this piece

Cutting off trade with tariffs would force a huge interest-rate spike and probably a debt crisis, because the budget deficit would have to be financed at home.

Second-order thinking

  1. John H. Cochrane Economist at the Hoover Institution But the spike in interest rates require to do this would be huge. And the trade shock will cause a sharp recession, or worse, putting even more stress on the budget. A debt crisis is likely along the way as the US finds it impossible to roll over debt.

The cure for the trade deficit is to tax consumption instead of saving and investment, and to stop borrowing to fund consumption.

Businesses raise prices only when their accounts force them to, not when they can see the cost coming.

Customers leave faster when prices rise than they come back when prices fall, which is why sellers hold prices as long as they can.

The price level behaves as the aggregate of mostly backward-looking decisions rather than as an asset price, except during hyperinflation, so expected future primary balances barely affect it today.

  1. Olivier Blanchard Economist; former chief economist of the International Monetary Fund I believe that, except in times of hyperinflation, the price level does not behave as an asset price but as the aggregate of billions of mostly backward-looking decisions, and that expectations of future primary balances have little effect on the price level today.

High electricity prices are what is killing European industrial competitiveness.

  1. John H. Cochrane Economist at the Hoover Institution The average European and UK voter, once he or she moves on from immigration, will notice how Europe and the UK have made energy unaffordable, stopped its growth-exactly as degrowthers wish-and deindustrialized, on the altar of climate policies that do nothing to improve the climate.

A country cannot fund its own industrial strategy and call the same policy cheating when China does it.

Tariffs on Chinese clean energy reduce the total number of clean-energy jobs, because most of those jobs are in deployment rather than manufacturing.

Second-order thinking

  1. Hannah Ritchie Data scientist at Our World in Data and author of Not the End of the World That’s because most clean energy jobs are in deployment and maintenance rather than manufacturing, and since higher costs slow down the rollout of renewables, increasing prices reduces the total number of people working in clean energy (even if the number working in manufacturing increases).

Europe cannot keep the world's strictest environmental and social rules, invest less than its competitors and run a more naive trade policy, and still expect to create jobs.

Trade-offs

  1. Emmanuel Macron President of the French Republic since 2017 We cannot sustain the most stringent environmental and social norms, invest less than our competitors, have a more naive trade policy than them and think that we will continue to generate jobs. This no longer holds together. Speech on Europe, Sorbonne, 25 April 2024 (Elysee English transcript)elysee.fr · 25 Apr 2024

Where the claims collide

Asserted relations, each with the curator’s reason — never computed, because similarity cannot tell agreement from opposition.

Cochrane says the right answer is unilateral free trade and that the rest is explaining why the objections fail. Macron says Europe cannot run a more naive trade policy than its competitors and still expect to create jobs, which is the objection stated as a policy. One of them is describing the other as naive.

Macron says Europe cannot run a more naive trade policy than its competitors and still expect to create jobs. Ritchie says tariffs on Chinese clean energy cut the total number of clean-energy jobs, because most of them are in deployment rather than manufacturing and higher prices slow the rollout. Both are counting jobs, and they count them in opposite directions.

The predicted interest-rate spike follows only if the trade deficit is the capital surplus seen from the other side. If foreigners are not financing the budget deficit by buying American assets, closing the trade gap does not force domestic savings to replace them.
