Description
The cod stock in the North Sea is threatened by overexploitation. To recover this fishing stock, pressure needs to be reduced. This implies that catch compositions with small amounts of cod are preferred by public policy makers. The present analysis assesses the technological efficiency of fishing trips, considering landings of cod as an undesirable output. A non-parametric frontier technology approach based on directional distance functions is applied to explore alternative fishing activities for Danish gill netters operating in the North Sea with the goal of protecting the cod stock. Since the performance observed on different fishing trips may be under influence of the external operating environment, a four-stage approach introduced by Fried et al. (1999) is applied to correct for such exogenous factors. The corrected directional distance function efficiency scores reveal the behavioural inefficiencies, i.e., prospects for decreasing the catch of cod while catch of other species are increased.

Description
This workshop aims bringing together both professionals and academics interested in the
fields of efficiency and productivity in banking and finance. There is a widespread need to
continuously assess the efficiency of banks and their restructuring to avoid financial crises
and bankruptcies. Global threats to banking and financial systems can no longer be ignored.

Description
We introduce an axiomatic framework to analyze the perception of inequality across distributions with different total income. The main result is the characterization of a new two parameters generalized version of the inequality equivalence criterion (IEC), the Flexible IEC (FIE). This criterion is able to encompass all the most used criteria of inequality equivalence and is sufficiently flexible to provide a perception consistent with evidence from questionnaire investigations, namely that the inequality perception goes from the relative view (focussing on income shares) to the absolute view (focussing on absolute income differentials) as incomes increase. One parameter of the FIE is associated with the Bossert and Pfingsten (Math. Soc. Sc. 1990) Intermediate IEC (IIE) while the other is shown to lead to an alternative single parameter version of the IEC, the Proportional IEC which is dual to the previous. We provide independent characterizations both of PIE and IIE. Also alternative IECs existing in the literature are characterized within the axiomatic framework suggested. These results are consistent with those obtained in the surplus sharing literature and recently in the inequality measurement literature. Moreover they can provide insights on risk comparisons of lotteries with different expected value.

Description
We exhibit three non-standard cases of preference reversal (PR) between choices and valuations of bets. PR patterns diverge whether asking prices or bidding prices are used to elicit values, a finding not well explained by contingent weighting theory. PR also occurs when a lottery is confronted with a sure gain, which is inconsistent with regret theory. Lastly, PR does not require small probabilities of winning for the riskier bet. The endowment effect arises as a surprising consequence of the WTA/WTP disparity when the probabilities of winning get close to certainty. Due to the presence of a small uncertainty regarding goods which one does not own and to a discontinuity of WTP close to certainty, people underestimate the value of goods not owned but do not overestimate the value of goods owned. We consider a new theory of choice under risk, cognitive consistency (CC) theory (Lévy-Garboua 1999), which can predict both standard and non-standard cases of PR, the WTA/WTP disparity and the endowment effect in the context of single choices with a single parameter added to risk aversion. We show that the BDM mechanism and the random lottery incentive system are incentive-compatible if subjects have preferences which satisfy CC theory. A new experiment is designed to test the predictions of CC versus other theories of PR and the endowment effect. The experimental results strongly support CC predictions, reject the regret theory explanation for PR and the loss aversion explanation for the endowment effect, and allow direct estimation of risk aversion and the additional parameter of CC theory with no restriction on the utility function.

Description
Available empirical evidence suggests that skewness preference plays an important role in understanding asset pricing and gambling. This paper establishes a skewness-comparability condition on probability distributions that is necessary and sufficient for any decision maker’s preferences over the distributions to depend on their means, variances and, third moments only. Under the condition, an Expected Utility maximizer’s preferences for a larger mean, a smaller variance, and a larger third moment are shown to parallel respectively his preferences for a first-degree stochastic dominant improvement, a mean-preserving contraction, and a downside risk decrease and are characterized in terms of the von Neumann-Morgenstern utility function in exactly the same way. The condition and its characterizations permit a rigorous evaluation of the available empirical evidence on skewness preference in the context of asset pricing and gambling. By showing that all Bernoulli distributions are mutually skewness comparable, we further show that in the wide range of economic models where these distributions are used individuals’ decisions under risk can be understood as tradeoffs between mean, variance, and skewness. Our results on skewness-inducing transformations of random variables can also be applied to analyze the effects of progressive tax reforms on the incentive to make risky investments.

Description
The effect of a change in wealth on its allocation between two attributes is examined for three classes of utility function that generate non-linear sharing rules. Our results allow for a very wide range of applications: the Arrow-Debreu contingent claims case, the risk-sharing problem, including the standard portfolio choice, intertemporal individual consumption, the demand for insurance and tax evasion.

Description
From a managerial point of view, surprise gifts offer more opportunities than gifts
suggested by recipients, because a larger part of the selection and purchase processes remains to
be molded. Research shows that unexpected gifts that surprise are especially valued by recipients,
but the extant literature on gift selection and purchase explicitly takes into account neither the
giver’s intention to surprise nor the consequences for gift selection and purchase processes.
