PERKS - Trade & Barter allows you to adjust the value of the Investor and Master Trader perks. This should work even if you have another mod that alters the Speech tree. Options: set either perk to 5000 max. You can set independently adjust the amounts required to invest and the amount of gold the merchant receives. However, when you make the initial investment, this money will be available until spent. Trade & Barter also adds to the Investor Perk by providing merchants with increased inventories when you invest in them. Increased inventories are unique to each individual merchant.

“Economic theory has always got to be historically bounded,” Beggs says. “I think it’s a mistake to think you’ll find the workings of modern money by going back to the origins of money.” He does point out that, while barter may not have been widespread, it’s possible that it happened somewhere and led to money, just given how much is unknown about such a large period of time.

An alternate currency, denominated in labour time, would prevent profit taking by middlemen; all goods exchanged would be priced only in terms of the amount of labour that went into them as expressed in the maxim 'Cost the limit of price'. It became the basis of exchanges in London, and in America, where the idea was implemented at the New Harmony communal settlement by Josiah Warren in 1826, and in his Cincinnati 'Time store' in 1827. Warren ideas were adopted by other Owenites and currency reformers, even though the labour exchanges were relatively short lived.[20]
Michael Linton originated the term "local exchange trading system" (LETS) in 1983 and for a time ran the Comox Valley LETSystems in Courtenay, British Columbia.[22] LETS networks use interest-free local credit so direct swaps do not need to be made. For instance, a member may earn credit by doing childcare for one person and spend it later on carpentry with another person in the same network. In LETS, unlike other local currencies, no scrip is issued, but rather transactions are recorded in a central location open to all members. As credit is issued by the network members, for the benefit of the members themselves, LETS are considered mutual credit systems.

No, said Mises, for if taken back far enough, there comes a point at which money first emerges as a medium of exchange out of a pure barter economy Prior to this, it is valued only for its non-monetary uses as a commodity The demand for money is therefore pushed back to the last day of barter, where goods are traded only in direct exchange, and where the temporal element of the regression theorem ends It is in this way that all charges of circularity are obviated. 

If you experience odd or unexplained amounts of merchant gold, even after the merchant has restocked, then you probably have another mod loaded after Trade & Barter which has altered the VenderGold leveled lists. To resolve the issue either: 1) Change the load order, and make sure that Trade & Barter loads after the other mod, or 2) Click the "Disable Merchant Gold Options" option from the menu. This will reset the Merchant Gold options and allow the changes from the other mod to prevail without further interference from Trade & Barter.
There are several disadvantages of the barter economy. Firstly, there has to be double coincidence of wants for exchange to take place. Again the problem of indivisibility of commodities comes in the matter of exchange. Basically such disadvantages and many more called for the emergence of money. Money is used as a common medium of exchange and store of value.
