Users of online worlds such as Second Life and World of Warcraft transact millions of dollars worth of virtual goods and services every day, and these virtual economies are beginning to draw the attention of real-world authorities.

"Right now we're at the preliminary stages of looking at the issue and what kind of public policy questions virtual economies raise -- taxes, barter exchanges, property and wealth," said Dan Miller, senior economist for the Joint Economic Committee of the U.S. Congress.

The increasing size and public profile of virtual economies, the largest of which have millions of users and gross domestic products that rival those of small countries, have made them increasingly difficult for lawmakers and regulators to ignore.

Second Life, for example, was specifically designed by San Francisco-based Linden Lab to have a free-flowing market economy. Its internal currency, the Linden dollar, can be converted into U.S. dollars through an open currency exchange, making it effectively "real" money.

Inside Second Life, users can buy and sell virtual objects from T-shirts to helicopters, develop virtual real estate, or hire out services ranging from architecture to exotic dancing. Up to $500,000 in user-to-user transactions take place every day, and the Second Life economy is growing by 10 to 15 percent a month....

The rapid emergence of virtual economies has outstripped current tax law in many areas, but there are some clear-cut guidelines that already apply. For example, people who cash out of virtual economies by converting their assets into real-world currencies are required to report their incomes to the U.S. Internal Revenue Service or the tax authority where they live in the real world.

It is less clear how to deal with income and capital gains that never leave the virtual economy, income and capital gains that in the real world would be subject to taxes.

This piece briefly describes the self-enforcing and non-pecuniary resource allocation system used by players in virtual worlds to allocate goods produced by a combination of player effort (the effort required to organize a group and overcome challenges) and the game itself (which “generates the good” – the input here is the time of the design staff).
