EXPERIMENTAL STUDIES OF CONSUMER DEMAND BEHAVIOR USING LABORATORY ANIMALS*

Using laboratory animals as subjects, two series of experimental studies of consumer demand behavior are reported. The experiments show that laboratory animals will change consumption patterns in response to changes in the budget set, consuming more of the lower priced commodities and less of the higher priced commodities. Large rotations in the budget line for essential commodities resulted in severe disruption of consumer behavior. The experiments demonstrate the feasibility of using non-human subjects in laboratory studies of economic behavior.     

MIGHT MAKES RIGHTS: A THEORY OF THE FORMATION AND INITIAL DISTRIBUTION OF PROPERTY RIGHTS

This paper is a theoretical and empirical investigation into the formation and initial distribution of property rights. Violence is singled out as a major constraint on this formation process. Its role is explicitly modeled in a choice theoretic framework and some of the implications are tested using data collected from contracts written during the California gold rush of 1848.     

RESPONSE LATENCY AS A SIGNAL TO QUESTION PROBLEMS IN SURVEY RESEARCH

This research explores the potential utility of response latencyas an index of question problems in survey research. The timerespondents took to answer three types of bad questions wascompared to the time they took to answer the repaired versionsof the questions. Questions containing a superfluous negativeand double-barreled questions took longer to answer than nearlyidentical questions without these problems. Repaired versionsof questions soliciting frequency estimates, however, took longerto answer than their problematic counter parts. The resultsare discussed in the context of a model of question answering,and their implications for survey methodology are explored.
