This paper analyses the properties of Dickey-Fuller (1979) (DF) unit root tests in the presence of trend mis-specification. It is shown that while the performance of the DF coefficient test is as expected, the DF test in its t-ratio form exhibits unusual behaviour. In particular it is found that...

Interest in prediction markets has increased in the last decade, driven in part by the hope that these markets will prove to be valuable tools in forecasting, decision-making and risk management - in both the public and private sectors. This paper outlines five open questions in the literature,...

We report on several experiments on the optimal allocation of ownership rights. The experiments confirm the property rights approach by showing that the ownership structure affects relationship-specific investments and that subjects attain the most efficient ownership allocation despite starting...

Is a fair degree of equality among economic agents with respect to income and wealth compatible with an optimal level of economic growth - or does initiatives promoting equality restrain growth, or in the opposite, does initiatives promoting growth restrain equality? These are questions that...

The paper investigates risk attitudes among different types of individuals. The authors use several different measures of risk attitudes, including questions on choices between uncertain income streams suggested by Barsky et al. (1997) and a number of ad hoc measures. As in Barsky et al. (1997)...

This paper outlines a method of procuring the benefits of deception in experiments without actually deceiving subjects, which should be suitable for many experimental economics environments. This is done by a modification of an already standard design, the Random Lottery incentive system, which...

Information asymmetries are important in theory but difficult to identify in practice. We estimate the presence and importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major...

Potential poverty traps among the rural poor suggest a need to reduce poor farmers?vulnerability by stabilizing crop yields and limiting yield losses. Advances in biotechnology will help address this need directly with crops that tolerate climate fluctuation or resist biotic stresses. Evaluating...

We report an experiment designed to investigate markets with consumer search costs. In markets where buyers are matched with one seller at a time, sellers are predicted to sell at prices equal to buyers' valuations. However, we find sellers post prices that offer a more equal division of the...
