 Altairian's economy is most likely representative of which system:
Interplanetary ruling. I've got three million credits sitting in the Terran Consulate on Altair V, just waiting for me to walk in and pick them up. And the Terran Consulate isn't willing to sell all the trading possibilities here down the river just to get you out of a mess. Altair I had been recognized at once by the Trading Commission as a commercial prize of tremendous value, but early reports had warned of the danger of wildcat trading on the little, musty, jungle-like planet with its shaggy, three-eyed inhabitants—warned specifically against the confidence tactics so frequently used—but there was always somebody, Meyerhoff reflected sourly, who just didn't get the word. "If you hadn't been so greedy, you'd have found out what a chunk of land was to these natives before you started peddling it. You've probably never heard that there are just too many Altairians here for the food their planet can supply, and their diet is so finicky that they just can't live on anything that doesn't grow here. And consequently, land is the key factor in their economy, not money; nothing but land. They've built up the most confusing and impossible system of barter and trade imaginable, aimed at individual survival, with land as the value behind the credit. They have only the haziest idea what truth represents, and they've shrugged off the idea as impossible and useless."
