The Binarized Scoring Rule

Review of Economic Studies 2013 80(3), 984-1001
We introduce a simple method for constructing a scoring rule to elicit an agent's belief about a random variable that is incentive compatible irrespective of her risk-preference. The agent receives a fixed prize when her prediction error, defined by a loss function specified in the incentive scheme, is smaller than an independently generated random number and earns a smaller prize otherwise. Adjusting the loss function according to the belief elicitation objective, the scoring rule can be used in a rich assortment of situations. Moreover, the scoring rule can be incentive compatible even when the agent is not an expected utility maximizer. Results from our probability elicitation experiments show that subjects' predictions are closer to the true probability under this scoring rule compared to the quadratic scoring rule.

US political corruption and quarterly conference calls

Journal of Banking & Finance 2024 161, 107108
We find that managers obfuscate during conference calls when their firm's headquarters is in a politically corrupt state, and they do so to shield assets from corrupt officials. The positive association between corruption and obfuscation by managers is much stronger when the expropriation risks are higher, such as when the firm (a) does not pay dividends, (b) is making a profit, (c) has more cash, (d) has fewer subsidiaries, and (e) is not making any political contributions. We do not find evidence that managers obfuscate during conference calls to hide their self-dealing.
