Bayesian Analysis for a Theory of Random Consumer Demand: The Case of Indivisible Goods

McCausland (2004a) describes a new theory of random consumer demand. Theoretically consistent random demand can be represented by a \"regular\" \"L-utility\" function on the consumption set X. The present paper is about Bayesian inference for regular L-utility functions. We express prior and posterior uncertainty in terms of distributions over the indefinite-dimensional parameter set of a flexible functional form. We propose a class of proper priors on the parameter set. The priors are flexible, in the sense that they put positive probability in the neighborhood of any L-utility function that is regular on a large subset bar(X) of X; and regular, in the sense that they assign zero probability to the set of L-utility functions that are irregular on bar(X). We propose methods of Bayesian inference for an environment with indivisible goods, leaving the more difficult case of indefinitely divisible goods for another paper. We analyse individual choice data from a consumer experiment described in Harbaugh et al. (2001).

Two models of constitutionalism and the legitimacy of law : Dicey or Marshall ?

The article was first published in the Oxford University Commonwealth Law Journal.

General Legitimacy of Judicial Review and the Fundamental Basis of Constitutional Law

Four questions dominate normative contemporary constitutional theroy: What is the purpose of a constitution? What makes a constitution legitimate? What kinds of arguments are legitimate within the process of constitutional interpretation? What can make judicial review of legislation legitimate in principle? The main purpose of this text is to provide one general answer to the last question. The secondary purpose is to show how this answer may bear upon our understanding of the fundamental basis of constitutional law. These two purposes should suggest particular answers to the first three questions.

Toward a Political Theory of Environmental Policy.

This paper makes some steps toward a formal political economy of environmental policy. Economists' quasi-unanimous preferences for sophisticated incentive regulation is reconsidered. First, we recast the question of instrument choice in the general mechanism literature and provide an incomplete contract approach to political economy. Then, in various settings, we show why constitutional constraints on the instruments of environmental policy may be desirable, even though they appear inefficient from a purely standard economic viewpoint.

La constitutionnalisation de la juridiction inhérente au Canada : origines et fondements

Bien que la juridiction inhérente des cours superIeures constitue une notion souvent utilisée par les tribunaux au Canada, plusieurs facettes importantes de cette notion demeurent inconnues et incomprises. Le présent mémoire s'attarde à retracer l'origine et les fondements des pouvoirs inhérents afin d'en expliquer la constitutionnalisation dans l'ordre constitutionnel canadien contemporain. Pour ce faire, nous avons retracé l'essence des pouvoirs inhérents au moyen d'une démarche historique afin d'énoncer une théorie constitutionnelle cohérente des pouvoirs inhérents qui permettra de juger du bien-fondé de leurs nombreuses manifestations contemporaines. L'enchâssement de la juridiction inhérente dans la Constitution canadienne repose sur le statut, la nature et les caractéristiques uniques des cours supérieures. Plus particulièrement, le principe constitutionnel de l'indépendance judiciaire constitue le fondement contemporain de la constitutionnalisation de la juridiction inhérente. Cette constatation permet alors d'avancer l'idée selon laquelle les pouvoirs inhérents nécessaires au maintien de l'indépendance judiciaire des cours supérieures doivent être élevés au rang de normes constitutionnelles supralégislatives.

The Effect of Public Spending on Consumption: Reconciling Theory and Evidence

Recent empirical evidence from vector autoregressions (VARs) suggests that public spending shocks increase (crowd in) private consumption. Standard general equilibrium models predict the opposite. We show that a standard real business cycle (RBC) model in which public spending is chosen optimally can rationalize the crowding-in effect documented in the VAR literature. When such a model is used as a data-generating process, a VAR estimated using the artificial data yields a positive consumption response to an increase in public spending, consistent with the empirical findings. This result holds regardless of whether private and public purchases are complements or substitutes.
