Is sustainable growth optimal?

This paper analyzes sustainable growth in a stochastic environment, with human extinction as a possible outcome. The basic constraint of sustainability is that consumption never decreases over an infinite horizon, which requires that the probability of extinction be maintained at zero. We show that this problem can be examined in a standard optimal-growth model. Under certain conditions, the solution of this problem is a corner solution with probability of survival equal to one, at the cost of economic growth. These conditions depend on the initial development level and on the elasticity of utility with respect to consumption. In some circumstances, which depend on the social discount rate, optimal-growth paths do not exist. In these situations, the sustainable-growth concept has a clear autonomy with respect to the usual optimality criterion.     

Rent seeking and the allowed rate of return: A recursive model

In this paper, we estimate a three-equation recursive model of the rate-of-return phase of the regulatory hearing process. Separate equations are estimated for the firm's requested rate of return, the staff's recommended rate of return, and the commission's approved rate of return. The sample used in this estimation contains 122 observations of actual rate cases that were decided between 1980 and 1984. There are 73 electric companies and 37 states represented in this sample. The model differs from prior work in this area by (1) incorporating a separate equation to explain the commission staff's recommended rate of return, and (2) including the regulated companies' actual expenditures on the hearing process as a variable in all three equations.     

Aggregate insider trading and market returns: The role of transparency

Using a sample of countries that require timely disclosures of insider trades, I investigate the effect of country‐level institutions that promote transparency on the extent to which aggregate insider trades predict market returns. I find that financial information transparency mitigates the predictive content of aggregate insider trades when markets are more likely to deviate from fundamentals (i.e., during market fads), and when there is greater co‐movement in stock prices. In contrast, there is some evidence that governance and investor protection mitigate the association between aggregate insider trades and future earnings surprises. Hence, holding constant the timely disclosures of insider trades, other capital market institutions play complementary roles in mitigating the informational frictions that give rise to the predictive content of aggregate insider trades.

The Short‐Term Economic Impact of Levying E‐Tolls on Industries

TERM is used to analyse the short‐term regional economic impact of an increase in industries' transport costs when paying E‐Tolls. Market‐clearing and accounting equations allow regional economies to be represented as an integrated framework, labour adjusts to accommodate increasing transportation costs, and investments change to accommodate capital that is fixed. 1 1 TERM is a bottom‐up CGE model designed for highly disaggregated regional data. The Enormous Regional Model's originate from Horridge et al. ( 2005 ) and are better explained in Horridge ( 2011 ).
We concluded that costs from levying E‐Tolls on industries are small in comparison to total transport costs, and the impact on economic aggregates and most industries are marginal: investments (?0.404%), gross domestic product (GDP) (?0.01) and consumer price inflation (?0.10%). This is true even when considering costs and benefits on industries as well as consumers. Industries that experienced the greatest decline in output were transport, construction and gold. Provinces that are closer to Gauteng and have a greater share of severely impacted industries experienced larger GDP and real income reductions. Mpumalanga's decrease in GDP was 17% greater than Gauteng's.     

Pro-social Motivation and the Delivery of Social Services

This article provides an overview highlighting some major themesof the recent literature on the role of pro-social motivationin the provision of social services. We focus on the insightsobtained from two alternative ways of modelling pro-social motivation;action-oriented and output-oriented altruism. This literaturehas implications regarding the design of optimal incentives,the selection of motivated agents and its interaction with monetaryrewards, and the optimal organizational form required to exploitsuch motivations. We also discuss the implications for governmentprovision of social services from the perspective of a parallelliterature that emphasizes the non-contractible nature of output,and contrast it with the implications derived from work emphasizingthe role of pro-social motivation.

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.     

Business Cycles, the Exchange Rate, and Demand for Antidumping Protection in Mexico

Antidumping actions in the US and EU are known to be linked to macroeconomic conditions. In part, this is because positive injury findings may be easier to make in a downturn, increasing the chance of success for complainants. We explore the evidence for Mexico, one of the main “new” antidumping regimes. Injury determination is also critical in Mexico’s antidumping policy, as a majority of unsuccessful complaints have been rejected because of negative injury findings rather than negative findings of dumping. Working with data from 1987 to 2000, we provide evidence for a relationship between macroeconomic factors and antidumping complaints, including current account and exchange rate movements, and both local and global general macroeconomic conditions.
