Default BTN trade partner listing for just one world

Hello Folks,
What follows is a data dump giving people an idea of just how honking HUGE the trade set up is when using the rules from GURP TRAVELLER FAR TRADER.

The "format" of the information was something I am using for a program I wrote (quick and dirty - so it ain't pretty and it ain't finished!) I have a subroutine that will calculate distances between hexes in an XXYY format such that 2124 would become 21 for the X value and 24 for the Y value. Below are "Trade Partners" for any given world pairing that matches the criteria of having a BTN of 6.5 and higher. What I did was take into account the distance penalty involved, and if memory serves me correctly, corrected for different states (Sword World not being Imperial, while Lunion being Imperial for example). What I didn't code for was whether or not the world had a trade pairing (Ag to NA or In to Ni). That only would have increased the BTN value by .5 in any event.

Home Hex/World Name/Destination Hex/Destination World Name/BTN/Distance in parsecs

Lunion Alone has some 321 Trade partners whose BTN values exceed 6.5.

What prompted me to dump this here was a conversation elsewhere regarding ports and economics involved and trying to estimate the shipping volume required to carry on the required trade.

Note: I had to cut this into two segments because the combined character total was 11376, had to cut it into two parts. Sorry!

IMO and IIRC, a key issue with the system in Far Trader is that there is no mechanism for calculating "this route is swamped by trade from closer worlds and thus peters out", which would go a long way toward making the trade routes make sense. As-is, there is measurable trade between worlds that plausibly wouldn't trade at all.

There are four steps of decreasing trade with distance. So if you start with a BTN over 17, even if the worlds are on the other side of the Imperium they still have some trade with one another. If you took that table and changes the distances to be additive rather than a log scale for distances to reduce trade it would go along way to fix this problem.

IMO, the problem with GTFT is not the method, but the details...

The drop off for range isn't factoring in the different shipping capabilitites by TL (nor significantly enough by world).

And as was noted above, by RandyB, nearer suppliers killing trade isn't accounted for.

At TL 9, J6 is 12 weeks round trip comm time, and at least 14 weeks travel time round trip.

By comparison, US-UK-France-Belgium have had telegraph at several hours round trip to any major city; if the recipient is waiting, a return message means under a day round trip for the message. And crossing times for the atlantic to under a week by commercial steamer since the 1880's. So one could order and have goods at NY or Atlanta by the following week, and pretty much anywhere in the US within 3. Shipping times of 6-8 weeks being an allowed standard including 1-2 weeks post for the order.

While I agree in theory, that closer competitors will have an edge, part of the problem is this:

Best as I can figure, a 40' x 8' x 10' trailer (just giving ideas here) would be equal to 3200 cubic feet of volume, or roughly 6 dtons worth of freight/cargo. When dealing with abstracts, the law of comparative advantage isn't be accounted for in the sense that 6 dtons of freight from the longer distance world isn't the same as the 6 dtons of freight from the closer. One could contain nuts and bolts of varying sizes - the output of a week's work from a single factory, while another could be plastics manufactured goods, the output of a single day from another factory. We're not comparing apples to apples here. So - saying that a closer market should have dibs over the overall economic picture isn't in line with the law of comparative advantage.

Now, let's take another example - again, using GURPS TRAVELLER. Let's say we have four Rifles packed in a crate that measures 2' x 4.5' x 1.5'. It only contains four rifles valued at say, 830 credits each. Times four brings the value of the package to 3320. Volume works out to 3.675 cubic feet. That works out to roughly 136 units per dton of volume right? Let's make it simple and assume that we're only shipping 130 units of 4 rifles or roughly 520 rifles. Total value is 431,600 credits. Now, ship that for a total of 30 parsecs at say, 800 credits per parsec. Total cost works out to 800 x 30 or 24,000 credits to ship. Wait, did I say 30 parsecs? Let's make it 100 parsecs. At 100 parsecs at 800 credits per dton, we've just increased the cost of those rifles by another 80,000. Dividing that by the 520 rifles, the additional cost to the rifles is only 153 some odd credits per rifle.

Ok, maybe it wasn't rifles being shipped, it was nuts and bolts. Per "crate" cost is different than per dTon cost, etc.

Even if you match the value of the goods worth in shipping fees, the question comes down to whether or not you can even get the goods because no one nearby is manufacturing it, and if the locals found that they could make more money manufacturing that which is going for double its normal value after shipping from the long distance location - you still run into the situation where to produce more goods of something they weren't making before, something else ends up not being produced by the near by manufacturer because they only have so much in the way of labor, capital goods to produce more manufactured goods, and so much material that may or may not be in abundance at the nearer location.

So - do I have a problem with the long distance trade? Not particularly because we're not dealing with specifics - only generalities. I do however, note that when dealing with this kind of approach, that the author himself indicates that it was a SIMPLE two world gravity model, but that the reality would involve more worlds, more trade partners, etc. It was an abstraction that had been simplified (Ye gads, GURPS TRAVELLER FAR TRADER was simplified!!!!)

In any event, I have problems wrapping my mind around the level of trade that is being assumed in each instance where BTN is greater than 6.0 (Ie 6.5+). Dividing the dton tonnage by around 5 or 6 gives you a ballpark for how many tractor trailer's worth of contents involved. Then you compare that against real life just to see if it even makes sense. But for a world that is barely able to meet the 6.5 threshold, but having 30 or so HIGH industrial worlds within a given range, seems to produce more trade than the world has people. THAT to me seems wrong. But, I'm not an expert and I only have two semesters in economics in addition to my accounting background (plus programming as a major plus history and psychology and sociology classes). I know enough to be dangerous to myself alas.

You should make that file available in the files section. What would be of even more value in my opinion, is an analysis of how many tons of ships are involved in handling ALL of the trade at any given time.

For instance? I was looking at "real distance" versus "Jump Distance" and found that the range varied by around 25% more than the real distance. In other words, sometimes you could find a star that was say 20 parsecs away, and be able to do it in 10 jumps with a Jump-2 ship, but (per my limited data set with Spinward Marches), it seemed to hover around 12 or so Jumps to actually get there due to the stars not making a perfect bee-line of stepping stones (so to speak). So a trade pair with 10 jumps between it, would require a total of 10 "sets" of starships to carry that trade - as compared/contrasted against a world pair that could be reached in one jump. Why? Because the ship's going from world A to world B in one week, will also require trade from World B to A in one week (Ie twice the ships required for the total tonnage). But those ships would be jumping back and forth every other week. The one that is 10 jumps away, will have a total of 9 ships in transit when the 10th set is on the planet.

My point is - getting a total number of hulls is useful for multiple reasons. Gives an idea of how much fuel has to be made available for the traffic, how much ore has to be mined to produce the starship hulls, and how many hulls are likely out there at any given time. If by definition, tramp freighter hulls are 800 dtons or less, it would be fun knowing how many (in theory) free trader hulls there are supposed to be out there at any given time.

Ah, gotta love this hobby - it's more entertaining than calculating how many Angels can dance on a pinhead (None, Angels can't dance).

Containers are available in common standard lengths of 20-ft (6.1 m), 40-ft (12.2 m), 45-ft (13.7 m), 48-ft (14.6 m), and 53-ft (16.2 m). United States domestic standard containers are generally 48-ft and 53-ft (rail and truck). Container capacity is measured in twenty-foot equivalent units (TEU, or sometimes teu). An equivalent unit is a measure of containerised cargo capacity equal to one standard 20 ft (length) 8 ft (width) 9 ft in (height) container. In metric units this is 6.10 m (length) 2.44 m (width) 2.59 m (height), or approximately 38.5 m.
(interfreight.co.za, accessed 23 may 2016)
1 TEU = 38.5 cubic meters, which is 2.75 Td (at 14 per Td).
