CHOICES BETWEEN SIMPLE AND COMPOUND LOTTERIES: EXPERIMENTAL EVIDENCE AND NEURAL NETWORK MODELLING.

Zizzo, D.J. - Department of Economics, Oxford University - 2001

An experiment on choices between single and compound lotteries is presented, and results are calibrated with neural network models. Many subjects tend to average out probabilities, though behaviour becomes more rational with more exposure to compound lotteries in the practice stage. The Prior...

Combining Top-down and Bottom-up Accountability: Evidence from a Bribery Experiment

Serra, Danila - Department of Economics, Oxford University - 2008

Monitoring corruption typically relies on top-down interventions aimed at increasing the probability of external controls and the severity of punishment. An alternative approach to fighting corruption is to induce bottom-up pressure for reform. Recent studies have shown that both top-down...

Probability Compounding in Words and in Practice

Zizzo, Daniel John - Department of Economics, Oxford University - 2002

The conjunction fallacy occurs whenever probability compounds are thought of as more likely than its component probabilities alone. In the experiment we present, subjects chose between simple and compound lotteries after some practice. Depending on the condition, they were given more or less...

Discriminating between Models of Ambiguity Attitude: A Qualitative Test

Mukerji, Sujoy; Cubitt, Robin; Kuilen, Gijs van de - Department of Economics, Oxford University - 2014

The exchange between Epstein (2010) and Klibanoff et al. (2012) identified a behavioral issue that sharply distinguishes between two classes of models of ambiguity sensitivity, exemplified by the Î±-MEU model and the smooth ambiguity model, respectively. The issue in question is whether a...

Risk Pooling, Commitment, and Information: An experimental test of two fundamental assumptions

Barr, Abigail - Department of Economics, Oxford University - 2003

information that underpin current models of risk pooling. A specially designed economic experiment involving 678 subjects across … attempts to conduct such tests. I find that more extrinsic commitment is associated with more risk pooling, but that more … information is associated with less risk pooling. The first of these results accords with our expectations and assumptions. The …

The effects of externalities and framing on bribery in a petty corruption experiment

Barr, Abigail; Serra, Danila - Department of Economics, Oxford University - 2008

Using a simple one-shot bribery game, we find evidence of a negative externality effect and a framing effect. When the losses suffered by third parties due to a bribe being offered and accepted are high and the game is presented as a petty corruption scenario instead of in abstract terms...

Conflict of interest as a barrier to local accountability

Barr, Abigail; Zeitlin, Andrew - Department of Economics, Oxford University - 2011

Using a specially designed lab-type experiment conducted in the field, we compare the willingness of head teachers, centrally appointed public servants, and community representatives to hold Ugandan primary school teachers to account. We find no difference in the willingness of centrally...
