This study examines some antecedents and consequences of ethical leadership. Using a dataset from the King James Version of the Bible, I argue for and propose that maternal influence will lead to leaders being ethical while paternal influence appears to have no impact on leaders being ethical. I also argue and propose that ethical leaders are more likely to achieve longer tenures and to lead their organizations to better performance. I develop propositions based on the findings from the analysis of (...) my qualitative and quantitative data. (shrink)

In 1957, Edgar Lobel published an Oxyrhynchus papyrus containing anonymous commentaries to poems of Alcman which has not ceased to fascinate philologists and historians of ancient philosophy.

Much behavioral welfare economics assumes that expected utility theory does not accurately describe most human choice under risk. A substantial literature instead evaluates welfare consequences by taking cumulative prospect theory as the natural default alternative, at least where description is concerned. We present evidence, based on a review of previous literature and new experimental data, that the most empirically adequate hypothesis about human choice under risk is that it is heterogeneous, and that where EUT does not apply, more choice is (...) characterized by rank-dependent utility models than by CPT. Most of the apparently loss-averse choice behavior results from probability weighting rather than from direct disutility experienced when an outcome is framed as a loss against an idiosyncratic reference point. We then consider implications of this finding for methodological debates about how to model welfare effects of policies, and argue that abandonment of a dogmatic belief in CPT as the correct theory of risk human choice exposes a conceptual error that is widespread in behavioral welfare economics. We provide concluding reflections on second-order, philosophical issues around the grounding of normative commitments in policy-focused economics. (shrink)

A principal source of interest in behavioral economics has been its advertised contributions to policies aimed at ‘nudging’ people away from allegedly natural but self-defeating behavior toward patterns of response thought more likely to improve their welfare. This has occasioned controversies among economists and philosophers around the normative limits of paternalism, especially by technical policy advisors. One recent suggestion has been that ‘boosting,’ in which interventions aim to enhance people’s general cognitive skills and representational repertoires instead of manipulating their choice (...) environments behind their backs, avoids the main normative challenges. A limitation in most of this literature is that it has focused on relatively sweeping policy recommendations and consequently on strong polar alternatives of general paternalism and strict laissez faire. We review a real instance, drawn from a consulting project we conducted for an investment bank, of a proposed intervention that is more typical of the kind that economists are more often actually called upon to offer. In this example, the sophistication of current tools for preference attribution, combined with philosophical externalism about the semantics of preferences that makes it less plausible to attribute their literal self-conscious representation to people as propositional attitude content becomes more tightly refined, blocks applicability of the distinction between nudging and boosting. This seems to call for irreducible, context-specific ethical judgment in assessing the appropriateness of the forms of paternalism that economists must actually wrestle with in going about their everyday business.

Nobody in this debate questions the point that neuroeconomics remains full of potential, and little else as yet. If so, that really is progress of sorts. I was getting afraid that we would have to open nominations for the Captain Ahab Award for obsessive work on the promotion of neuroeconomics.

If someone claims that individuals behave as if they violate the independence axiom when making decisions over simple lotteries, it is invariably on the basis of experiments and theories that must assume the IA through the use of the random lottery incentive mechanism. We refer to someone who holds this view as a Bipolar Behaviorist, exhibiting pessimism about the axiom when it comes to characterizing how individuals directly evaluate two lotteries in a binary choice task, but optimism about the axiom (...) when it comes to characterizing how individuals evaluate multiple lotteries that make up the incentive structure for a multiple-task experiment. We reject the hypothesis about subject behavior underlying this stance: we find that preferences estimated with a model that assumes violations of the IA are significantly affected when one elicits choices with procedures that require the independence assumption, as compared to choices elicited with procedures that do not require the assumption. The upshot is that one cannot consistently estimate popular models that relax the IA using data from experiments that assume the validity of the RLIM. (shrink)

In any list of famous last words, Socrates' are likely to figure near the top. Details of the final moments of celebrities tend anyway to exert a peculiar fascination upon the rest of us: life's very contingency provokes a need to see lives nevertheless as meaningful organic wholes, defined as such precisely by their final closure; so that even the most trivial aspects of their ending can come to seem bearers of profound significance, soliciting moral reflections apparently not less urgent (...) for their being quite unwarranted. From earliest times, this fascination with last moments has come to be concentrated in particular upon last words: situated at that most mysterious of borders, between life and death, they seem to look backwards and forwards at once, judging the speaker's own past life from the vantage-point of a future realm he is about to attain and hinting at the nature of what awaits us all from the perspective of that past life he still – however tenuously – shares with us. A moment earlier, and there is no reason to privilege any one discourse of the speaker's above another; a moment later, and his lips are sealed for ever. Only in that final moment can he seem to pass an unappealable judgement on himself, to combine in a single body two incompatible subjectivities, the one suffering and extremely mortal, the other dispassionate and transcendent. If he is a thinker or a man of action, this is his last chance to summarize a lifetime's meditation or experience in a pithy, memorable aphorism.If he is a celebrated poet, he can be imagined to have composed his own epitaph; if he is a Hellenistic poet, he may even in fact have done so.

We develop an extension of the familiar linear mixed logit model to allow for the direct estimation of parametric non-linear functions defined over structural parameters. Classic applications include the estimation of coefficients of utility functions to characterize risk attitudes and discounting functions to characterize impatience. There are several unexpected benefits of this extension, apart from the ability to directly estimate structural parameters of theoretical interest.

The essay, based on four years of living and teaching philosophy in Brazil, is a series of aphorisms about food and hunger as concerns that have left their mark on the Brazilian mind. Alimentary jokes and homilies are retold, gustatory episodes are recalled, larders and cuisines remarked, markets and mealtimes remembered—with constant reference to the idiom of Brazilian Portuguese. The style of thinking is “postphilosophical” in the sense developed in Part II of the author's Negative Dialectics and the End of (...) Philosophy[Longwood, 1990]: it does not so much argue theses as it displays the character of the topic. (shrink)

Abstrac: In an extended discussion, within the context of a"philosophy offorestry", of the relationships of the concepts of truth and of tree some fundamental aspects of occidental metaphysics are examined from a Heideggerian perspective. But the paper tries to go beyond Heidegger's thematization of metaphysics in the context of pre-Socratic philosophy by establishing Indo-European etymology as a more inclusive horizon. In this manner, the transition from anti-metaphysics to post-metaphysics is anticipated.

Evidence of risk aversion in laboratory settings over small stakes leads to a priori implausible levels of risk aversion over large stakes under certain assumptions. One core assumption in statements of this calibration puzzle is that small-stakes risk aversion is observed over all levels of wealth, or over a â sufficiently largeâ range of wealth. Although this assumption is viewed as self-evident from the vast experimental literature showing risk aversion over laboratory stakes, it actually requires that lab wealth be varied (...) for a given subject as one evaluates the risk attitudes of the subject. We consider evidence from a simple design that tests this assumption, and find that the assumption is strikingly rejected for a large sample of subjects from a population of college students. We conclude that the implausible predictions that flow from these assumptions do not apply to one specialized population widely used to study economic behavior in laboratory experiments. (shrink)

Psychologists can learn from the procedural conventions of experimental economics. But the rationale for those conventions must be examined and understood lest they become constraints. Field referents and the choice of heuristic, matter for behavior. This theme unites the fields of experimental psychology and experimental economics by the simple fact that the object of study in both cases is the same.
