Modelling the choice between regulation and liability in terms of social welfare

Abstract.  Using a formal political economy model with asymmetric information, we illustrate the conditions under which an environmental protection system based on extending liability to private financiers is welfare superior, inferior, or equivalent to a system based on an incentive regulatory scheme subject to capture by the regulatees. We explicitly consider the following factors: the cost of care and its efficiency in reducing the probability of an environmental accident, the social cost of public funds, the net profitability of the risky activities, the level of damages, and the regulatory capture bias. We characterize in such a parameter space the regions where one system dominates the other. JEL classification: D82, K32     

Overcompensation as a Partial Solution to Commitment and Renegotiation Problems: The Case of Ex Post Moral Hazard

In a Costly State Verification world, an agent who has private information regarding the state of the world must report what state occurred to a principal, who can verify the state at a cost. An agent then has what is called ex post moral hazard: he has an incentive to misreport the true state to extract rents from the principal. Assuming the principal cannot commit to an auditing strategy, the optimal contract is such that: (1) the agent's expected marginal utility when there is an accident (high‐ and low‐loss states) is equal to his marginal utility when there is no accident; (2) the lower loss is undercompensated, while the higher loss is overcompensated; and (3) the welfare of the agent is greater under commitment than under no‐commitment. Result 2 is contrary to the results obtained if the principal can commit to an auditing strategy (higher losses underpaid and lower losses overpaid). The reason is that by increasing the difference between the high and the low indemnity payments, the probability of fraud is reduced.     

Capacity Commitment versus Flexibility

We show how technological flexibility choices and equilibrium configurations (both simultaneous and sequential duopoly) depend on six industry characteristics. Low market volatility combined with intermediate market size favors inflexible technologies; large values of either volatility or size favor flexible technologies; low or intermediate values of both favor the coexistence of flexible and inflexible technologies. The possibility of a flexibility trap exists in industries of low volatility and intermediate size. Entry prevention can sometimes be achieved by inflexible technologies or flexible technologies, depending on the industry characteristics.     

Rethinking the role of NCBs in the EMU

Five years after the introduction of unified monetary policy in the EMU, some member countries are wondering whether they have ceded too much of their policy-making powers. The fact that National Central Banks no longer carry out sizable expansionary open market or foreign exchange market operations suggests that they face substantially reduced abilities to set economic policy.This paper demonstrates that, in fact, very little power has been yielded: on the fiscal front, the force of such policy initiatives is enhanced by the fixity of the exchange rate. On the monetary front, we show that there is an observational equivalence between all Central Bank actions under fixed exchange rates. This implies that the authorities retain the same amount of policy flexibility as before. So long as they use an alternative form of policy initiative, carrying out what previously would have been characterized as sterilized foreign exchange market operations, their ability to influence the macro performance of their economy is undiminished.

Unlocking the potential of advanced manufacturing technologies

This research examines whether investments in advanced manufacturing technologies (AMTs) such as flexible manufacturing systems (FMS), computer aided design (CAD), computer aided manufacturing (CAM), robotics, etc., are more likely to lead to improved performance if they are supported by improvements in the manufacturing infrastructure of the company. This question is evaluated using data gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Multiple item scales are developed and adapted from sources in the literature to measure investments in technology, infrastructure, and the performance of the plant. Evidence supporting the reliability and validity of these scales is provided. Hierarchical regression is used to analyze the relationship between technology, infrastructure, and performance. The results suggest that there is an important interaction between the adoption of advanced manufacturing technologies and investments in infrastructure. Firms that invest in both AMTs and infrastructure perform better than firms which only invest in one or the other. Separate analyses on sub-samples of firms with the highest and lowest investments in AMTs show that infrastructural investments have a stronger relationship with performance in the high investment group. Thus, the data indicate that infrastructural investments provide a key to unlocking the potential of advanced manufacturing technologies.     

Sequential location equilibria under incomplete information

Summary We consider a simple model of incomplete information in location theory. Two firms compete in a two stage framework: a sequential location stage and a price competition stage. Firm 1 knows both its own constant marginal cost technology and that of Firm 2, whereas the latter has incomplete information about firm 1's technology. The location stage turns out to be a monotonic signaling game and theunique D1 equilibrium is a pure strategy separating equilibrium if firm 1's cost advantage is below some bound, and otherwise a pooling equilibrium if the prior probability that Firm 1 is of the low cost type is high, or a semi-pooling equilibrium if it is low. This surprising result is due to the fact that the location gap between the two types of Firm 1 is bounded because of natural economic reasons, which may prevent the separation of the two types. Hence, incomplete information matters: the equilibrium locations differ quite significantly from the full information equilibrium locations.We would like to thank an anonymous referee for very helpful comments and also the participants in seminars at GREQE (Marseille), Université de Montréal, UBC, HEC (Paris), in the Location Theory session of the World Congress of the Econometric Society (Barcelona) and in the Game Theory Conference at the University of Western Ontario for their comments.

Conditions of Use of Data-processing Charge-back Systems: A Pilot Study

Previous researchers could not find empirical support for a relationship between the characteristics of the data-processing charge-back system and the impacts on the organization. The lack of empirical evidence may be caused by a missing variable problem. This paper proposes an intermediary variable: the use of the charge-back system. This research finds an empirical relationship between the characteristics of the system and its use. A pilot study was conducted to investigate the conditions of use of data-processing charge-back systems in organizations. For operations costs, results indicate that the variability of the charges, user's authority over data-processing activities and user involvement in the budgetingprocess are the important factors in explaining the use of a budget report. As for development costs, the quality of the information on the charges and user involvement in the budgeting process are the most important factors. However, the authors wish to caution readers that this is a pilot study with a convenience sample of twenty-five questionnaires collected from seven firms. Résumé Par le passé, les chercheurs n'ont pu établir de support empirique pour la relation existant entre les caractéristiques d'un système informatique d'imputation des coǔts et son impact sur l'entreprise. Le manque de preuves empiriques peut ětre dǔ à un problème de variable manquante. Cette étude propose donc une variable intermédiaire: L'usage du système d'imputation des coǔts. Cette recherche a établi une relation empirique entre les caractéristiques du système et son usage. Une étude pilote a été menée pour étudier les conditions d'utilisation de systèmes informatiques d'imputation des coǔts dans les entreprises. Quant aux frais d'exploitation, les résultats indiquent que la variabilité des imputations, le contrǔle de l'utilisation sur les activités informatiques et le rǒle de l'utilisateur dans l'élaboration du budget constituent des facteurs importants dans la justification d'un rapport budgétaire. Quant aux frais de développement, la qualité des données relatives aux frais et le rǒle de l'utilisateur dans l'élaboration du budget sont les facteurs les plus importants. Les auteurs désirent cependant prévenir les lecteurs qu'il s'agit d'une étude pilote comportant un échantillon de 25 questionnaires recueillis auprès de 7 entreprises.
