The private costs and benefits of environmental self‐regulation: which firms have most to gain?

A (correctly designed) voluntary self‐regulatory scheme can – in theory – improve social welfare if the benefits to society outweigh the costs. However, businesses may not choose to participate in a voluntary scheme if their private benefits do not outweigh their costs; external benefits are irrelevant to the profit maximizing firm. This paper reviews literature on self‐regulation, primarily focusing on factors that influence the net private benefits of environmental programmes. The literature is summarized in a manner that allows one to identify characteristics of firms that are most likely to accrue positive net benefit from environmental programmes, and to determine ways in which self‐regulatory bodies might raise those benefits, thereby increasing participation rates.

A Theoretical Model of the Effects of Public Funding on Saving Decisions by Charitable Nonprofit Service Providers

Why do charitable nonprofit, service‐providing organizations save? What are the tradeoffs between using income to build up cash reserves and serving more clients? Saving may generate income, protect the organization against a drop in donations, and increase the organization's chances of survival. Saving, though, may affect the likelihood that nonprofits receive private and public funding. We model the relationship among private and public income, economic conditions, and nonprofit savings. We find that anticipation of government help during difficult times tends to reduce the amount of saving done by the nonprofit. This effect is strengthened if government officials view unspent donations as indicative of a lack of need. Both these effects provide a strong incentive for nonprofits to spend on current consumption rather than to save for the future, and thus to increase the burden on the public purse.     

Global Entrepreneurship Monitor: Data Collection Design and Implementation 1998–2003

The Global Entrepreneurship Monitor research program was designed as a comprehensive assessment of the role of entrepreneurship in national economic growth. The conceptual model reflected in a wide range of factors associated with national variations in entrepreneurial activity and the major contextual features. Empirical tests of the many relationships in the model required four major data collection activities: adult population surveys, unstructured interviews with national experts, self-administered questionnaires completed by national experts, and assembly of relevant standardized measures from existing cross-national data sets. Adult population surveys were implemented to identify those entrepreneurially active, which required a set of precise criteria and careful processing to ensure harmonized counts and prevalence rates across 41 countries. Existing evidence on measures of reliability indicates that the measures met contemporary standards and the project was cost-effective.     

Cities of the imagination: Science fiction, urban space, and community engagement in urban planning

Stories, dreams, histories and myths, Michel de Certeau argues, connect people to particular places and makes place concrete and inhabitable. These narratives generate an imaginary, poetic geography that haunts the abstract city of street maps and development plans, and makes it socially meaningful. This paper is concerned with one particular kind of story-telling - science fiction - and its relationship with the city, urban planning, and questions of community engagement. The paper argues that the ‘cities of the imagination’ generated by science fiction and other forms of narrative provide a powerful means of understanding, communicating and enriching the connections to place in urban communities. Moreover, science fiction is often characterised by its ability to explore the future of cities. This gives the genre a fascinating and potentially useful resonance with urban planning as a discourse and set of practices; and, in particular, strategies for engaging communities in the design process and, thus, designing for future social sustainability. These ideas will be tested through a reading of near-future urban spatiality in the cyberpunk stories of William Gibson. The theorisation of the relationship between urban space and narrative in the work of de Certeau and other theorists will be used to help frame this discussion.

“Continuous” budgeting: Reconciling budget flexibility with budgetary control

This paper explores the role of budgeting in the context of the more flexible modes of management required in conditions of uncertainty. It contributes to the growing literature on the tensions between the need to meet specified financial targets, as expressed in budgets, and the need for more flexible and innovative forms of managing prompted by heightened market volatility and rapid rates of technological change. Drawing on case study evidence, the paper introduces the notion of “continuous budgeting” to highlight the ways in which one organization sought to reconcile these potentially conflicting objectives. By integrating different uses of budgeting with other management controls, the processes of “continuous budgeting” encouraged managers to use their discretion in operational matters when confronted by unexpected events. Consequently, it enabled managers to prioritise, as necessary, the revision of plans and reallocation of resources in order to meet wider strategic organizational objectives. As well as empowering managers, “continuous budgeting” also imposed strict accountabilities to ensure that managers remained committed to achieving their own and the organization’s financial targets. Thus far from being an obstacle, budgeting contributed effectively to both the flexibility and the financial discipline required for effective strategy implementation.     

Loan guarantees and credit supply

The efficiency of federal lending guarantees depends on whether guarantees increase lending supply or simply act as a subsidy to lenders. We use notches in the guarantee rate schedule for Small Business Administration (SBA) loans to estimate the elasticity of bank lending volume to loan guarantees. We show significant bunching in the loan distribution on the side of the size threshold that carries a more generous loan guarantee. The excess mass implies that increasing guarantee generosity by one percentage point of loan principal would increase per-loan lending volume by $19,000. Excess mass increases in periods with guarantee generosity, and placebo results indicate that the effect disappears when the guarantee notch is eliminated.     

Reflections on per diems in international development projects: Barriers to and enablers of the project cycle

The concept of what a per diem is and who should receive one is a complex idea that, within the development context, can either support or hinder the achievement of development projects’ goals. This paper seeks to explain the evolving nature of per diems and their use within the development context; explore how they serve as barriers or enablers in achieving project goals; and touch on their impact on the development project cycle. Through a 3-year-long internationally funded development programme in Malawi and South Africa, the authors compare lessons drawn from their experience with existing literature to determine the practicalities of paying per diems and address the question: To what extent do per diems support or hinder international development projects?
