The trade in guns and drugs on the Mexico-US border

 It's well known that a lot of illegal drugs enter the U.S. over the border with Mexico.  Less well known in the U.S. is that a lot of guns cross illegally into Mexico over that border, destined for Mexican drug cartels.  

Here's a story from the Guardian:
How Texas’s gun laws allow Mexican cartels to arm themselves to the teeth by Sam Garcia.

"Despite Mexico’s well-documented high levels of violence, legally purchasing guns there is actually quite difficult. The nation of nearly 130 million people has a single store that can legally sell guns.

...

"Mexican foreign affairs ministry legal adviser Alejandro Celorio Alcántara estimates that half a million guns annually are purchased legally in the US and then brought into Mexico illegally. About 70% of guns seized in Mexico from 2014 to 2018 and submitted for tracing had originally come from the US, according to officials with the American bureau of alcohol, tobacco, firearms and explosives (ATF).

Here's another report:

Dribs and Drabs: The Mechanics of Small Arms Trafficking from the United States

"Robust arms export licensing regimes are necessary but not sufficient for stopping small arms trafficking. Many of the traffickers studied did not apply for arms export licences or attempt to exploit licensing exemptions; they simply bypassed the licensing system entirely. At the same time, recent examples of attempted and successful diversion of authorized small arms exports highlight the continued need for rigorous licensing and post-shipment end-use monitoring.

"Arms trafficking from the United States goes well beyond gun-running to Mexico. Traffickers in the 159 cases studied shipped weapons, parts, ammunition, and accessories to at least 46 countries and foreign territories on six continents. Intended recipients of these items range from Honduran farm workers to a Finnish motorcycle gang 

"The illicit trade in parts and accessories for small arms is more significant than commonly assumed. Networks that traffic in firearms parts are among the most prolific and geographically expansive of the smuggling operations studied"

Global chocolate production and consumption

This map  of cocoa production and consumption from the Cocoa Barometer 2020 would make it easy to guess which way is North (were it not for Australia)...

Global markets in antiquity: olive oil and wine

Markets are ancient human artifacts, and a recent paper in the EJ suggests that markets of global scale, based on comparative advantage and international trade, are older than previously recognized.  Global (or at least international) agricultural markets are ancient, according to pollen data on crops and population in ancient Greece:

Landscape Change and Trade in Ancient Greece: Evidence from Pollen Data  by Adam Izdebski, Tymon Słoczyński, Anton Bonnier, Grzegorz Koloch, Katerina Kouli, The Economic Journal, Volume 130, Issue 632, November 2020, Pages 2596–2618, https://doi.org/10.1093/ej/ueaa026

"Abstract: In this article we use pollen data from six sites in southern Greece to study long-term vegetation change in this region from 1000 BCE to 600 CE. Based on insights from environmental history, we interpret our estimated trends in the regional presence of cereal, olive and vine pollen as proxies for structural changes in agricultural production. We present evidence that there was a market economy in ancient Greece and a major trade expansion several centuries before the Roman conquest. Our results are consistent with auxiliary data on settlement dynamics, shipwrecks and ancient oil and wine presses."


" We demonstrate that in a period of apparent population growth southern Greece decreased its relative production of cereals. We also observe a simultaneous increase in the relative importance of olives and vines. Since southern Greece had a comparative advantage in the production of olive oil and wine, we interpret this result as evidence of a trade expansion. The growing demand for wheat could only have been satisfied by massive grain imports, perhaps from the Black Sea region, which were offset by exports of olive oil and wine. These commodities were in high demand in Greek colonies and other neighbouring areas, which needed them for cultural reasons but were not always able to produce them locally."

Plasma and plasma products (such as antibodies) are a big business (and the U.S. dominates the international market)

These days I'm thinking about corona virus covid-19 convalescent blood plasma, which I blogged about yesterday, and about which I hope to say more soon. But that has gotten me to think again about blood plasma generally, which is a source of many therapies, including antibodies, immunoglobulins, that defend against a large variety of diseases.

The U.S. is the Saudi Arabia of blood plasma and plasma products, with both a large domestic commercial market and annual exports valued in the billions of dollars. The reason is largely that it is legal in the U.S. to pay plasma donors, so there's ample supply through a big network of hundreds of  for-profit and nonprofit blood and plasma centers (the nonprofits mostly don't pay donors, I think). In many countries, paying their residents for plasma is repugnant and illegal. Fortunately for their citizens, they mostly don't also suffer from severe shortages of life-saving plasma medicines, because it can be bought from the U.S. (See e.g. my posts on Canada's plasma policies.)

Here are some relevant export figures. They make clear that the U.S. exports billions of dollars of plasma, and tens of billions of dollars of plasma products.




For those who would like to study these data, let me explain where they come from.  (They  include some things that aren't plasma products, and may miss some that are...) It's not so easy to find the U.S exports of exactly blood plasma and plasma products (I needed some help).

In Chapter 30 of the U.S. International Trade Commission (USITC) Harmonized Tariff Schedule (HTS),is the code:
HTS 3002: "Human blood; animal blood prepared for therapeutic, prophylactic or diagnostic uses; antisera, other blood fractions and immunological products, whether or not modified or obtained by means of biotechnological processes; vaccines, toxins, cultures of micro-organisms (excluding yeasts) and similar products:
 Antisera, other blood fractions and immunological products, whether or not modified or obtained by means of biotechnological processes"

That sounds good, but it includes (aside from plasma products) things that I don't want to include e.g. Malaria diagnostic test kits, and Fetal Bovine Serum.

On the other hand the subcategory 3002.12.00  is for "Antisera and other blood fractions" which includes sub-subcategories for things I do want to include:
3002.12.10 Human blood plasma.
3002.12.20 Normal human blood sera, whether or not freeze-dried
3002.12.30 Human immune blood sera

And then there are are codes 3002.13.00, 14.00, and 15.00 which cover the promising (very similar) categories in which most of the immunoglobulins are probably found, but maybe some other things too:

Immunological products, unmixed, not put up in measured doses or in forms or packings for retail sale
Immunological products, mixed, not put up in measured doses or in forms or packings for retail sale
and
 Immunological products, put up in measured doses or in forms or packings for retail sale.

The place to go to turn these numbers into export figures is dataweb.usitc.gov  (But getting data there isn't completely straightforward, and I got help from Julia Fabens.)  The table above shows that whole plasma itself has over $2 billion of annual exports from the U.S., and together with plasma products, including those involving antibodies (immunological products) there are almost $20 billion of exports from the U.S.

So, I'm guessing that soon, if clinical trials show that antibodies against covid-19, are useful, they will become readily available, commercially, in plasma and in pharmaceuticals.  A year ago, those human antibodies didn't exist, and so there was no way to use it to help patient zero or the next many thousands.  But now there's a lot of it, more each day, in the blood of recovered patients.  And there's a whole industry devoted to collecting it and purifying the antibodies into "immunological products." 

I hope human antibodies against covid-19 are clinically useful, to help mitigate and cure the disease if not to prevent it, because my sense is that a vaccine is (at least) many months away.
