We develop a behavioral axiomatic characterization of exponentially discounted utility (EDU) over consumption streams. Given is an individual agent’s behavior in the market: assume a finite collection of purchases across periods. We show that such behavior satisfies a “revealed preference axiom” if and only if there exists a EDU model (a discount rate per period and a concave utility function o...

This paper shows that in a buffer stock saving model, wealth-to-income and other interesting variables have unique stable invariant distributions. Previously this ergodic property has only been conjectured and demonstrated numerically by means of simulations. The proof proceeds by extending earlier results about the existence and uniqueness of an ergodic distribution to Markov processes on non-...

Abstract Biases in legal decision-making are difficult to identify as type II errors (wrongful acquittals) hardly observable and I convictions) only observed for the subsample of subsequently exonerated convicts. Our data on first German soccer league allow us classify each referee decision accurately correct, error or error. The potential bias we interested is favoritism toward clubs with high...

Ekonomide belirsizlik, dış ticaret ve döviz kuru gibi makro ekonomik değişkenler üzerinde etkili olabilmektedir. Küreselleşmenin ilerlemesi ekonomilerin karşılıklı bağımlılığının artmasıyla birlikte uluslararası ticaret, ekonomide yaşanan belirsizlik ortamından güçlü bir şekilde etkilenmektedir. Literatürde ekonomi politika belirsizliğinin üzerindeki etkilerine ilişkin tam olarak görüş birliği ...

We develop a version of Afriat’s Theorem that is applicable to a variety of choice environments, beyond the setting of classical consumer theory. This allows us to devise tests for rationalizability in the context of choice data on lotteries, contingent consumption, and intertemporal consumption. We also establish a version of Richter’s Theorem that characterizes the strict rationalizability of...

The concept of linear risk tolerance is transferred from the expected utility framework to the two-parameter, mean-variance approach. We show how the requirement of a hyperbolical Arrow-Pratt index translates from the EU-approach into a condition on the marginal rate of substitution between return and risk in the two-parameter approach. As a spin-off from this translation, we derive a specific ...

This paper uses player/match level data drawn from five playing seasons of the English Premiership League (EPL) to test for the presence of a refereeing susceptibility to social pressure in the application of soccer’s commonest sanction, the yellow disciplinary card. Using both player-specific fixed and random effects models, tentative support for the proposition is uncovered. The estimated eff...

This paper develops axiomatically a revealed preference theory of reference-dependent choice behavior. Instead of taking the reference for an agent as exogenously given in the description of a choice problem, we suitably relax the Weak Axiom of Revealed Preference to obtain, endogenously, the existence of reference alternatives as well as the structure of choice behavior conditional on those al...

This paper provides preference foundations for parametric weighting functions under rank-dependent utility. This is achieved by decomposing the independence axiom of expected utility into separate meaningful properties. These conditions allow us to characterize rank-dependent utility with power and exponential weighting functions. Moreover, by allowing probabilistic risk attitudes to vary withi...
