This volume on experimental economics offers both new research grounds and a bird's eye view on the field. In the first part, leading experimental economists, among them Vernon S. Smith and Daniel Friedman, give inspiring insights into their view on the general development of this field. In the second part, selected short papers by researchers from various disciplines present new ideas and concepts to solving problems in the real world.

Zusammenfassung
This volume presents papers and speeches given in the Experimental E- nomics Week in Honour of Dr Vernon L. Smith held in Okayama and Kyoto, 13-17 December 2004, which consisted of Dr Smith's public speech and the International Conference on Experiments in Economic Sciences: New - proaches to Solving Real-world Problems. Despite having a short history, experiments are now considered indispensable in economics as in other ?elds of science and engineering. As Dr Smith's Nobel Prize (2002) shows, experimental economics has now established itself in modern economics. In such an environment, researchers are expected to developthetraditionwithnewideasinnew?eldsforsolvingvariousproblems in the real world. The Experimental Economics Week, which was organised to explore new ?elds for experiments with new approaches, provided a unique opportunity for those who were engaged or interested in experiments in their ?elds to discuss experimental approaches from various standpoints. Economic experiments broaden and deepen our understanding of human - haviour, the economy and their interdependence. Some experiments are - signed to observe how people behave. Experimenters control subjects' e- nomic environment to guess their strategies, which are not always apparent in the real world. The environment may be game-theoretic (a person's gain or loss is a?ected by other persons' actions) or non-game-theoretic. In either case what is checked is subjects' behaviour. Some experiments are done to see how market or other economic systems work.
