ON ANNOUNCED USA TARIFFS: ISOLATION IS KEY
(but it is not what you think ).
3d

MY TAKE: the biggest technical bullshit i have ever seen in my life

The suicidal method for calculating reciprocal tariffs by the "crack team" are explained here

1/n

ustr.gov/issue-areas/re…

you have probably seen the formula that these geniouses used to calculate the tariffs

The 2 key parameter are epsilon and phi, aka
Epsilon= elasticity of imports to 1% tariff increase
Phi= pass through of price increases due to tariffs

Xi exports
M1 imports

in order to calculate the reciprocal tariffs

epsilon was established at 4
Phi was established at 0.25

The result is that reciprocal tariffs are set at (exp-imp)/imp, aka trade defict/imports

why 4 and 0.25??

3/n
4
EPSILON

The 2 papers taken as a reference are

papers.ssrn.com/sol3/papers.cf…

sciencedirect.com/science/articl…

Papers state that tariffs can improve wealth of the deficit country.

Unfortunately they are papers on bilateral trade

Specifically on the trade deficit between china and USA

Papers says that tariffs to China should be between 10 and 25%, BUT NO TARIFF SHOULD BE IMPOSED TO EU AND ROW

Papers look at a "two-country model", not at global trade imbalances of the USA, or global trade

basically what is said is that if
1) i import a lot from you
and

2)you dont import a lot from me,

if i put tariff AND YOU DONT (variable isolation) i win

If we both put tariffs, we are both worse off

Like many papers the result are due to isolation of variables (partial equilibrium) hence real life occurrences could be very different
6/n

As debatable as result can be, the authors didnt even dream to advise the USA universal reciprocal tariffs to all the world

In essence the papers assumes no retaliation, so they isolate to obtain results

7/n

To fence off possible theorethical opposition ( NB i am ironic) the "crack team" also said that elasticity could be 2 instead of 4 (yeah you read it well)

The way i read it is that in case of retaliation, "Team Crack" would be happy to double the tariffs

nice no?

PHI

The other work cited in the "crack-(pot) team" manifesto is this

Phi is established at 0,25 by the "crack team"

what does the paper say on elasticity of prices to tariffs?

Phi is 0,943 in the paper

so a 20% tariff according to Cavallo, Gopinath et al would translate in a 18.8% price increase

But according to the "crack team" it would be 5%, citing the same paper

UH????

MY FINAL TAKE

"Isolation" is needed when your "Team" smokes "crack"

But in that case it is better not to be involved in international trade
