We consider a barter market with multiple types of indivisible goods. Konishi et al. [J. Math. Econ. 35 (2001) 1–15] showed that the core of this market may be empty. We define a normal form game for this market and consider its equilibrium outcomes. Assuming separable strict preferences, we show that the game has a unique Coalition-proof Nash allocation. This Coalition-proof Nash allocation is...

Kidney exchange is a barter market where patients trade willing but medically incompatible donors. These trades occur via cycles, where each patient-donor pair both gives and receives a kidney, and via chains, which begin with an altruistic donor who does not require a kidney in return. For logistical reasons, the maximum length of a cycle is typically limited to a small constant, while chains ...

Kidney exchange is a type of barter market where patients exchange willing but incompatible donors. These exchanges are conducted via cycles—where each incompatible patient-donor pair in the cycle both gives and receives a kidney—and chains, which are started by an altruist donor who does not need a kidney in return. Finding the best combination of cycles and chains is hard. The leading algorit...

A peer-to-peer complementary currency can be a powerful tool for promoting exchanges and building relationships on the Internet. i-WAT [1] is a proposed such currency based on the WAT System [2], a polycentric complementary currency using WAT tickets as its media of exchange: participants spontaneously issue and circulate the tickets as needed, whose values are backed up by chains of trust. i-W...

The paper tests the proposition that money generates value in trade. It examines the data for 5,746 Russian companies for 1997 and finds that money accounts for 24.6 percent of their value-added. The functional form of the return on money in trade is determined to be positive and marginally declining. The paper imputes that Russian GDP lost 8.1 percent in 1997 because of diminished use of money...

Property is rare in most nonhuman primates, most likely because their lifestyles are not conducive to it. Nonetheless, just because these species do not frequently maintain property does not mean that they lack the propensity to do so. Primates show respect for possession, as well as behaviors related to property, such as irrational decision making regarding property (e.g., the endowment effect...

This paper provides a unified analysis for the onset of the 1998 financial crisis and the strong economic recovery afterward in Russia and other former Soviet Union countries. Before the crisis a banking failure arose owing to the coexistence of a lemons credit market and high government borrowing. In a lemons credit market low credit risk firms switched from bank to nonbank finance, including ...
