“Remembrance of things past”: Gordon Tullock,the man and the bioeconomist

My tribute paper on Gordon Tullock (1922–2014) provides some memorable stories of Tullock as a person and as a founder of bioeconomics. I include my speech, “Toast and roast: Gordon Tullock,” delivered on the occasion of Tullock’s 80th birthday; also the same “Toast and roast....,” written in the form of a poem, “Ode to Gordon Tullock.” I also discuss Tullock’s contributions to bioeconomics. In a concluding section, I recall a couple of my poignant memories of Gordon Tullock.     

A Method to Evaluate Mode Effects on the Mean and Variance of a Continuous Variable in Mixed‐Mode Surveys

Les enquêtes à mode de collecte mixte, dans lesquelles le choix du mode de réponse est laissé aux personnes interrogées, sont de plus en plus répandues. Cette possibilité du choix du mode de réponse peut induire une confusion entre deux sortes d'effets : les effets de sélection et les effets de mesure. L'estimation séparée de ces deux effets est impossible à partir des seules données d'une enquête à mode de collecte mixte. Dans cet article, nous montrons comment la même estimation devient possible à partir d'une comparaison entre les résultats d'une enquête à mode de collecte mixte et ceux d'un enquête à mode de collecte unique basées sur le même questionnaire. La méthode que nous proposons permet d'estimer l'effet du mode de réponse sur la moyenne et la variance d'une variable de réponse continue. Elle est illustrée par l'estimation des effets du mode de réponse sur six questions relatives aux opinions vis‐à‐vis des enquêtes.     

Writing on the Wall: Street Art in Graffiti‐free Singapore

The legalization of graffiti in many cities has impacted urban landscapes and the way artists and the public view graffiti, street art and the city as well. This article considers the genesis, process and consequences of legal walls programmes firstly by introducing and differentiating the key terms ‘graffiti’, ‘street art’ and ‘legal walls’, then by examining an empirical case, that of Singapore. Renowned as a graffiti‐averse and litter‐free city, Singapore's recent about‐turn in legalizing illicit art forms illustrates changing government perspectives on creativity and legality in the country. Why the government has effected this change, how artists and members of the public have responded to it and the resultant art forms are critically explored. The conclusion reflects on four key lessons from Singapore for cities in general.     

Shifting the goal posts for design management in capital goods projects: 'design for maintainability'

Two case studies of capital goods projects, both of which were faced with new forms of demand for their products, are reported in this paper. In both cases, the contracting organisations involved were adjusting to new customer requirements for the long-term provision of the services associated with the capital goods they normally produced, rather than for the capital goods themselves. While both contracting organisations recognised the need to re-focus their equipment design efforts, to reflect the need for long-term service reliability (both contracting organisations were tied to penalties associated with agreed service levels), they nevertheless responded differently to this challenge, and their differing responses reflected the differing natures of the extended networks which comprised both projects and the organisational architectures in which the projects were themselves embedded. The paper explores the differing opportunities and barriers to the management of design in complex projects presented by these two case studies. In so doing it points to the conclusion that successful design management in complex projects can depend upon the successful management of the (multiple) contexts in which design takes place.     

Information-constrained optima with retrading: An externality and its market-based solution

This paper studies the efficiency of competitive equilibria in environments with a moral hazard problem and unobserved states, both with retrading in ex post spot markets. The interaction between private information problems and the possibility of retrade creates an externality, unless preferences have special, restrictive properties. The externality is internalized by allowing agents to contract ex ante on market fundamentals determining the spot price or interest rate, over and above contracting on actions and outputs. Then competitive equilibria are equivalent with the appropriate notion of constrained Pareto optimality. Examples show that it is possible to have multiple market fundamentals or price-islands, created endogenously in equilibrium.

The Impact of Mergers on Quality Provision: Evidence from the Airline Industry

We examine how mergers affect quality provision by analyzing five U.S. airline mergers, focusing on on‐time performance (OTP). We find that airline mergers have minimal negative impacts on OTP, and likely result in long‐run improvements due to efficiencies. Importantly, we show that this finding is not driven by post‐merger changes in price that could affect OTP. Consequently, at least in the case of airlines, policymakers should not, as a rule, fear the negative quality effects of mergers.
