The behaviour of expected short-term real interest rates in the UK

The existence of persistent technical inefficiency offers the opportunity for a ‘free lunch’ not typically implied by the neoclassical theory of the firm. When external effects are related to the use of particular inputs, reduction of persistent technically inefficient levels of input use represents a means of reducing external impacts. An important example is found in agriculture where substantial environmental impacts are generated by particular inputs. Within this context, this paper considers the usefulness of data envelopment analysis (DEA) for estimation of potential input reductions and assessment of potential reductions of environmental impacts of agricultural inputs. An application for French cereal production provides estimates that indicate that substantial potential exists for reduction of input use and environmental impacts.     

Market structure and corporate charitable donations: some Canadian evidence for 1976 and 1981

The business of business, not charity.

Say eleemosynary its more confusing.

Whatever, as long as we don't given 'em any cash.

Harv Antione, ‘The Buzz Words of Entrepreneurship’

in Apocryphal Northern Tales

This paper investigates the general determinants of corporate charitable donations in Canada and, in particular, the impact of imperfectly-competitive market structure. We utilize a profit-maximizing model and assume that charitable donations occur only if, by performing an advertising/public relations function, they increase revenue; or if, by acting as a fringe benefit, they result in a reduction in wage costs. In this context, because only firms in imperfect markets generate the rents from which donations can be made, we anticipate a positive relationship between donations and a measure of imperfect competition (concentration). The data is a cross-section sample of 38, 3- and 4-digit SIC manufacturing industries pooled for 1976 and 1981. The major findings are that: the results are generally compatible with the predictions of the model; concentration is a significant determinant of donations although non-linear; the cost of giving (the tax rate) is appropriately positive; and there are significant negative relationships for measures of foreign ownership and wage rates.     

The macroeconomic determinants of academic salaries in Australia

Nominal and real salaries at Australian universities are significantly affected by the behaviour of inflation and unemployment. Australian academics are not fully compensated for inflation. High unemployment has a marked negative effect on real salaries. Predicted changes in real salaries for various combinations of inflation and unemployment, calculated from the econometric model, yield pessimistic conclusions about the future outlook for real academic salaries.     

Amalgamations of universities:are there economics of scale or scope?

This paper estimates a multiple-output cost function for Australian universities. The estimates are used to evaluate the cost savings arising from the amalgamation of two or more institutions. These cost savings in turn are decomposed into those due to economics of scale and those due to economics of scope, using a new measure of economics of scope associated with the amalgamation of two institutions.     

International income shifting by US multinational corporations

This paper provides estimates of the amount of income shifted across national borders within the manufacturing operations of US multinational corporations (MNCs) in 1988. It is assumed that each MNC arranges its investments such that, after accounting for income shifting opportunities, the after-tax rate of return on a marginal investment is the same for all its affiliates, regardless of location. The income shifting is then inferred by comparing shares of after-tax profits, assets and sales of the affiliated members. It is estimated that such shifting amounted to about $8 billion (on net), which is less than 4% of the worldwide taxable income of the manufacturing MNCs.     

Compensating wage differentials for job stress

Recent medical studies have demonstrated a strong relationship between mental stress and cardiac events such as myocardial infarction and stroke. In the workplace, stress once accounted for less than 5% of all occupational disease claims, but it now accounts for over 15%. Although research on the effects of mental stress is increasing, few studies offer an economic perspective. In this paper, we examine the effects of job stress on weekly wages and explore the possibility that stress commands a compensating wage differential. Our findings suggest that, ceteris paribus, a wage differential does exist between workers experiencing mental stress and their ‘non-stressed’ cohorts. After controlling for other demographic and occupational factors, we found a statistically significant wage premium ranging from 3 to 10% attributable to mental stress. In addition, the magnitude of the differential varies by gender.     

The UK demand for steel

The paper suggests a short-run model of the demand for steel that may be used for forecasting future trends. The paper commences with consideration of a long-run model which is estimated using cointegration analysis. An error correction model is then developed to depict the short-run movements to equilibrium. This can be used for the purpose of ex-post forecasting.
