Finally: A withering away of cities?

Forecasters and science fiction writers have long predicted the demise of the city. It is argued that, with the cost of telecommunication likely to fall to near zero, one of the main reasons for agglomeration in cities will disappear and that the result will be a withering away of cities. This essay considers the likelihood of revolutionary change in the urban landscape and the implications for research by urban scholars.     

Public service and private gain

The Department of Education &; Science recently published details of the type of financial delegation schemes which schools will have to submit by September 1989. Together with other elements in the Education Reform Act, it is clear that delegation will give considerable scope to headteachers with the requisite abilities and attitudes to develop as general managers, and so create distinctive institutions which reflect their vision of what constitutes a good school.     

Regional Integration as Diplomacy

Regional integration agreements are examples of second-bestpolicies and have an ambiguous impact on welfare. This articlebuilds a model in which regional integration agreements unambiguouslyraise welfare by correcting for externalities. It assumes thattrade between neighboring countries raises trust between themand reduces the likelihood of conflict. The optimum interventionin that case is a subsidy on imports from the neighbor. Thearticle shows that an equivalent solution is for the neighboringcountries to tax imports from the rest of the world—thatis, to form a regional integration agreement—togetherwith some domestic taxes. The article shows that (1) the optimum tariffs on imports fromthe rest of the world are likely to decline over time; (2) deepintegration implies lower optimum external tariffs if it isexogenous; (3) optimum external tariffs are higher before deepintegration and lower thereafter if deep integration is endogenous;and (4) enlargement of bloc size (in terms of symmetric countries)has an ambiguous impact on external tariffs but raises welfare,and some form of domino effect exists.     

Measuring up to sustainability

As a concept sustainability has captured our imaginations and aspirations. As a tangible and identifiable goal it eludes us. Having developed indicators to measure and monitor economic, social and environmental conditions, we want now to measure sustainability. Our emphasis on the physical, the objective, and the rational, however, sees only the external manifestations of sustainability. The internal manifestations of sustainability, the non-material, the subjective, and the experiential, are put to one side, since they are messy, interpretive and time-consuming—the world of hermeneutics. Sustainability, however, is more than a `thing' to be measured, since it is about ecological integrity, quality of life and transformation or transcendence. Rather than ask how we can measure sustainability, it may be more appropriate to ask how we measure up to sustainability.     

Behavioural Microsimulation with Labour Supply Responses

This paper provides a technical survey of recent developments in behavioural microsimulation. We discuss the criteria by which models of labour supply may be chosen for application to behavioural microsimulation, and consider how such models may be augmented to control for fixed costs, child–related work costs, preference heterogeneity and endogeneity in wages. We describe methods by which non–linear budget constraints may be accommodated in estimation, policy simulations and welfare analysis, and discuss how stochastic terms may be factored into the simulation of behavioural responses to a policy shock.     

The role of instrumentation and process controls in minimizing accidental releases

Most accidental releases are the result of either mechanical failures or measures taken to prevent such failures, such as, venting through emergency vents, relief valves, or rupture discs. Where the mechanical failure is the result of defective materials, inadequate design, or external factors, little can be done by means of instrumentation to prevent the release. It may be possible, however, to reduce the flow. Many failures are due to process upsets such as overpressure, internal explosions, and runaway reactions. The probability of these failures occurring can be substantially reduced by proper instrumentation.     

Identity, appropriateness and the construction of regulatory space: the formation of the Public Accountant's Council of Ontario

Practice rights legislation in Canada continues to be contested 50 years after its first enactment. In Ontario, one of the earliest provinces to enact restrictive legislation, the challenges have focused on how the legislation has been implemented rather than on whether or not public accounting should be regulated. To better understand the contested issues in this field, we examine the process undertaken by the Public Accountants Council of Ontario to implement the Public Accountancy Act of 1950. Our analysis is based on the first 15 years of the minutes of the meetings of the Public Accountants Council for Ontario, augmented by other archival sources such as court cases, newspaper clippings, correspondence and reports. Our intent is to document the process and “logic of appropriateness” used by the Council to construct its identity and stake out its “regulatory space” in the face of the ambiguity of the law and pressure from interest groups. We also identify the contradictions that were institutionalized in this field resulting in repeated challenges to the Council. We conclude by relating the historical insights from this analysis to the continuing challenges to practice rights legislation in Ontario.
