Negligent hiring: Reducing the risk

In recent years, the responsibility of employers to hire people who are not dangerous or violent has been heightened by the tort, negligent hiring. The courts have ruled that certain employers owe a special duty to employees and third parties (e.g., customers or clients) to protect them from the harmful or criminal acts of other employees. This article contrasts negligent hiring to respondent superior and negligent entrustment, describes the components of negligent hiring, and reviews important legal cases. The article also discusses how employers can minimize the risk of negligent hiring through prudent human resource practices.     

Export Composition and Manufacturing Employment in the US during the Economic Downturn of 1991-92

This paper examines the effect that export composition had upon manufacturing employment in the US during the 1991 recession. Although it takes, on average, approximately $66 000 in exports to create one job, the exact gains in terms of total employment depend upon the labour-intensity of the products being exported. Foreign sales by the chemical and textile industries result in a far greater increase in employment than exports by the petroleum refining or steel industries. This analysis estimates the employment effects of manufacturing exports over the 1989-95 period, utilizing an input-output model to capture both direct and indirect effects. The results demonstrate that export composition has, at times, both strengthened and reduced demand for labour. Consequently, if job-creation is a national goal, it may be in the interests of the US to promote exports from sectors that are labour-using.     

Decomposing Redistributive Effects of Taxes and Transfers in Australia: Annual and Lifetime Measures

This paper decomposes the redistributive effect on annual and lifetime inquality of a range of taxes and transfers in Australia, using a dynamic cohort lifetime simulation model. The redistributive effect is decomposed into vertical, horizontal and reranking effects. Horizontal inequities in the tax and transfer system are found to be negligible. The extent of reranking is greater in the lifetime than in the annual context and is affected by the equivalence scales used to adjust household incomes. If no adjustment is made to household incomes, reranking is about nine per cent of the reduction in lifetime inequality. However, if each child is counted as equivalent to one-third of an adult, reranking is found to be less than one per cent.     

Strategy-proofness and Arrow's conditions: Existence and correspondence theorems for voting procedures and social welfare functions

Consider a committee which must select one alternative from a set of three or more alternatives. Committee members each cast a ballot which the voting procedure counts. The voting procedure is strategy-proof if it always induces every committee member to cast a ballot revealing his preference. I prove three theorems. First, every strategy-proof voting procedure is dictatorial. Second, this paper's strategy-proofness condition for voting procedures corresponds to Arrow's rationality, independence of irrelevant alternatives, non-negative response, and citizens' sovereignty conditions for social welfare functions. Third, Arrow's general possibility theorem is proven in a new manner.     

Corporate financial structure and the funding of private pension plans

One strand of the literature on the employment contract focuses on the role of the contract in the efficient sharing of risk between capitalists and workers. One way capitalists can shift risk to workers is to provide part of workers' remuneration in the form of an unfunded, deferred pension. Since bonds, in the event of bankruptcy or voluntary termination, are typically senior to unfunded pension liabilities, capitalists can also affect their risk by altering the firm's debt-to-equity ratio. These observations suggest that corporate financial structure and the employment contract are interdependent. The paper has two major goals. The first is to take a step towards integrating the theory of corporate financial structure with that of the employment contract. The second is to investigate possible consequences of legislation which regulates the funding of private pensions.     

Evolution of harvesting strategies: replicator and resource dynamics

Abstract. Economic theories of managing renewable resources, such as fisheries and forestry, traditionally assume that individual harvesters are perfectly rational and thus able to compute the harvesting strategy that maximizes their discounted profits. The current paper presents an alternative approach based on bounded rationality and evolutionary mechanisms. It is assumed that individual harvesters face a choice between two harvesting strategies. The evolution of the distribution of strategies in the population is modeled through a replicator dynamics equation. The latter captures the idea that strategies yielding above average profits are demanded more than strategies yielding below average profits, so that the first type ends up accounting for a larger part in the population. From a mathematical perspective, the combination of resource and evolutionary processes leads to complex dynamics. The paper presents the existence and stability conditions for each steady-state of the system and analyzes dynamic paths to the equilibrium. In addition, effects of changes in prices are analyzed. A main result of the paper is that under certain conditions both strategies can survive in the long-run. Correspondence to: J. Noailly     

Regulated firms in pollution permit markets with banking

This paper examines a competitive intertemporal market for bankable emission permits, such as sulfur dioxide allowances. Without profit regulation, firms are willing to bank permits if permit prices rise over time with the rate of interest, but will not bank if prices rise more slowly.The market achieves aggregate emission targets at least total cost if there is no profit regulation, but may not do so if firms are subject to profit regulation. Firms must arbitrage differences both in abatement cost and in the regulatory treatment of permits to achieve least total cost.The impetus for this work came from research we initiated during the Summer of 1990 for the Energy Information Agency.

We are grateful to the editor and two anonymous referees for stressing the importance of regulation in these markets and for their helpful and clarifying advice.
