Returns to scale and externalities in the consumption and investment sectors

Using data on US manufacturing, I estimate internal returns to scale and external effects for the consumption and investment sectors. I construct panels of data at the industry level and use results of gross output production function estimation to derive implied estimates in a value added specification. For the investment sector, returns to scale appear to be slightly increasing, with evidence of a positive external effect. For consumption, the evidence indicates decreasing to constant returns to scale. I discuss the implications of these results for the empirical plausibility of indeterminacy in recent multi-sector models of the business cycle.     

Annual Review Article 1995

This paper follows the pattern of most of its predecessors, first in serving as a record of events and developments in some areas germane to the employment relationship in Britain between October 1994 and October 1995, and second in offering some interpretative comment on elements of continuity and change. The decelerating economic recovery brought continuing but modest reductions in unemployment and some increase in price inflation. However, tax increases, perceived job insecurity, generally low earnings increases and other factors inhibited any widespread sense of economic well-being and restrained consumer demand. Among the key events were the TUC's strategic initiative on employee representation and union recognition, and the debates surrounding the Greenbury Report on executive remuneration packages and a national minimum wage. Industrial disputes reached record lows. Employment prospects, job insecurity and work-related stress were recurrent issues, with the different approaches of the main political parties to employment matters being clarified ahead of the coming general election.     

Offering a globally-linked international accounting course in real time: a sharing of experiences and lessons learned

This article reports the experiences from offering an online international accounting course that involved students from Japan, Spain, Switzerland, and the USA participating in real time via both audio and video links. In addition to interacting among themselves, students also interacted with accounting practitioners and standard setters from these countries. The latter attended class either in person or “virtually” via audio and video links. The paper also discusses the major benefits from the course, as identified by student feedback and direct faculty observations. A number of challenges in offering a course of this type also are identified. These insights can assist accounting educators interested in implementing a similar international accounting course at their institutions. They also have implications for applying distance-learning approaches in courses with a domestic focus.     

Police Pay and Bargaining in the UK, 1978–2000

Police pay and conditions in the UK are governed by a unique mechanism, the Police Negotiating Board. This paper reviews the circumstances in which it was set up and examines the outcomes, relative to other public service workers, over the first twenty years of its operation. Recent developments highlight the role of ministerial intervention and raise questions about the relationship between the PNB negotiating system and working practice at police force level.     

Ownership effects on operating strategies: Evidence of expense-preference behavior in the hospital industry

Expense preference offers an alternative to profit-maximization theory in explaining firms' operating strategies (Williamson, 1963; Rees, 1974). Expense-preference theory suggests that when disctretionary behavior is allowed, corporate managers may choose to maximize individual utility instead of corporate profit. Expense-preference behavior tends to be evidenced by higher expenditures on items for which managers have a positive personal preference than would be justified by profit maximization. Conditions under which significant managerial discretion can emerge include weak competition, strictly controlled entry, a high degree of regulation, separation of ownership and control, and existence of a strong public interest character for the firm or industry (Awh and Primeaux, 1985; Edwards, 1977). The hospital industry may be characterized as operating under all the above conditions. Hospital ownership can be classified as being either not-for-profit or proprietary. Profit-maximization influences are generally not present in not-for-profit hospitals, thus further increasing managerial discretion with respect to operating expenses. This study provides support for the contention that expense-preference behavior exists in not-for-profit hospitals as compared to proprietary hospitals. Specifically, we present evidence of considerable managerial discretion in the allocation of resources in not-for-profit hospitals.
