The Survival of Unique Corporate Cultures

In this paper we identify two situations that can lead a firm to hire an executive who supports a corporate culture that differs from the firm's current culture. In the first case, there is a similarity between the firm's culture and that of the candidate, and in the second case, executives who support the firm's culture constitute a minority of the available candidates. In both cases the firm prefers to hire an available candidate, rather than risk a prolonged vacancy. We show how these scenarios can lead to the eradication of unique cultures and to the perpetuation of more common cultures. Copyright © 2016 John Wiley & Sons, Ltd.     

Why Pay Taxes When No One Else Does?

In this paper we try to understand the phenomenon whereby a large proportion of the population evades tax payments. We present a model which incorporates elements from the theory of information cascades with the standard model of tax evasion and analyze the connection between the decision of a potential tax evader, the number of tax evaders, and the number caught in previous periods. General conditions exist under which any expected utility maximizing potential tax evaders will decide to emulate other tax evaders.     

A Definition of Uncertainty Aversion

A definition of uncertainty or ambiguity aversion is proposed. It is argued that the definition is well-suited to modelling within the Savage (as opposed to Anscombe and Aumann) domain of acts. The defined property of uncertainty aversion has intuitive empirical content, behaves well in specific models of preference (multiple-priors and Choquet expected utility) and is tractable. Tractability is established through use of a novel notion of differentiability for utility functions, called eventwise differentiability.     

Subjective states: A more robust model

We study the demand for flexibility and what it reveals about subjective uncertainty. As in Kreps [D. Kreps, 1979. A representation theorem for ‘preference for flexibility’. Econometrica 47, 565–577], Nehring [K. Nehring, 1996. Preference for flexibility and freedom of choice in a Savage framework. UC Davis Working Paper; K. Nehring, 1999. Preference for flexibility in a Savage framework. Econometrica 67, 101–119] and Dekel et al. [E. Dekel, B. Lipman, A. Rustichini, 2001. Representing preferences with a unique subjective state space. Econometrica 69, 891–934], the latter is represented by a subjective state space consisting of possible future preferences over actions to be chosen ex post. One contribution is to provide axiomatic foundations for a range of alternative hypotheses about the nature of these ex post preferences. Secondly, we establish a sense in which the subjective state space is uniquely pinned down by the ex ante ranking of (random) menus. Finally, we demonstrate the tractability of our representation by showing that it can model the two comparative notions “2 desires more flexibility than 1” and “2 is more averse to flexibility-risk than is 1.”     

Estimating the Effect of Redistricting on Minority Substantive Representation

This article applies modern Bayesian roll call analysis to estimatelegislators' support for minority-favored policies, and to determinethe likely impact of competing redistricting plans on the substantiverepresentation of minority interests. We first provide a theoryof districting and policy outcomes that points to the importanceof coalition building in advancing minority policy concernsand motivates our estimation techniques. We then apply thismethodology to the redistricting of the South Carolina StateSenate following the 1990 census. We show that this redistrictingled to more minorities being elected to office but less substantiverepresentation.

Inflation, asset prices, and the term structure of interest rates in monetary economics

This article offers a tractable monetary asset pricing model.In monetary economies, the price level, inflation, asset prices,and the real and nominal interest rates have to be determinedsimultaneously and in relation to each other. This link allowsus to relate in closed form each of the dependent entities tothe underlying real and monetary variables. Among other featuresof such economies, inflation can be partially nonmonetary andthe real and nominal term structures can depend on fundamentallydifferent risk factors. In one extreme, the process followedby the real term structure is independent of that followed byits nominal counterpart.     

Emergency relief vent sizing for fire emergencies involving liquid-filled atmospheric storage vessels

For large atmospheric vessels the potential occurrence of sufficient liquid swell resulting in two-phase flow is of special importance. Based upon an extension of analytical work it would appear justifiable to ignore two-phase flow effects for non-foamy systems.
