The geographic distribution of environmental inspections

Models of the enforcement of environmental regulations regarding point source pollution suppose that the probability of inspection or audit is independent across facilities. However, there are a number of reasons why regulators may choose to inspect many sites in a particular geographic area at one time. If the probability a site is inspected also depends on its compliance behavior, the expected payoff from choosing to violate will depend upon the compliance decisions of neighboring sites, creating a game of strategic interdependence between firms. In this paper, we use a dataset of inspections at petroleum storage sites in Manitoba between 1981 and 1998 to consider to what extent inspections are spatially correlated and whether inspection probabilities are a function of the inspection and violation history of the site and its neighbors. Further, we examine to what extent firms take into account whether their neighbors have been previously found in violation in determining compliance.     

Observation assistants: sitter effectiveness and industry measures

Patient safety remains a strategic goal and of societal importance for better health care. Direct observation remains an ineffective and expensive means of providing for patient safety. The nursing quality team found that using assessment tools helped to objectively categorize which patients are at risk. Defining patient volume, actual productive sitter usage, and assessing demand for patients in psychiatric crisis and patients at high risk to fall in the form of average daily census provided an easy-to-translate, familiar unit of measure to compare patient volume to demand and utilization. The sitter utilization case was unable to provide correlation of sitter use to decreased fall rates, elopement, or assault behaviors. Currently, there is no research to suggest the use of constant observation reduces the risk of patient harm related to their risk for falling or harming themselves.     

‘Wiped From the Map of the World’? Zanzibar,Critical Geopolitics and Language

This essay uses the case of Zanzibar in its complicated relationship with the United Republic of Tanzania (of which it is a part) as a lens on debates in political geography on empirical and conceptual approaches to critical geopolitics. We test the veracity of a multi-faceted critical geopolitics in the contemporary public contestation of Zanzibar's place in the United Republic from 2008–2012. We analyze Tanzanian media, the speech acts of Tanzanian leaders, and the key events and processes related to what is termed the ‘Zanzibar problem’ during the selected years, to make two points about a critical geopolitics approach: to strengthen critical geopolitics by broadening the analysis of language to engage political acts and languages beyond the Global North; and taking ‘subaltern geopolitics’ more seriously via engagement with critical geopolitical voices on discourses, events and processes from the Global South.     

Strategic candidacy for multivalued voting procedures

Dutta et al. (Econometrica 69 (2001) 1013) (Dutta, Jackson, and Le Breton—DJLeB) initiate the study of manipulation of voting procedures by a candidate who withdraws from the election. A voting procedure is candidate stable if this is never possible. We extend the DJLeB framework by allowing: (a) the outcome of the procedure to be a set of candidates; (b) some or all of the voters to have weak preference orderings of the candidates. When there are at least three candidates, any strongly candidate stable voting selection satisfying a weak unanimity condition is characterized by a serial dictatorship. This result generalizes Theorem 4 of DJLeB.     

Economic Analysis for the UK National Ecosystem Assessment: Synthesis and Scenario Valuation of Changes in Ecosystem Services

We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions.     

Tax Interaction Effects,Environmental Regulation,and “Rule of Thumb” Adjustments to Social Cost

Preexisting distortions in factor markets complicate the estimation of the social welfare effects of regulatory interventions. The existence of these tax interaction effects (TIEs) suggests that general equilibrium (GE) approaches should be used to evaluate regulatory policies. However, formal GE analysis is not always feasible for the numerous environmental regulations proposed by federal, state, and local agencies. The question addressed in this paper is whether an empirically based rule of thumb upward adjustment factor is appropriate to properly scale social cost estimates in environmental policy. We argue that such rule of thumb adjustments are significantly less reliable than estimates based on a detailed general equilibrium analysis because of the uncertainty about both the magnitude and sign of the social cost distortion. In addition to addressing this question, the paper gives an overview of TIEs and their relevance to environmental policy.     

Which International Institutions Promote International Trade?

This paper estimates the effect on international trade of three multilateral organizations intended to increase trade: (1) the World Trade Organization (WTO) and its predecessor the General Agreement on Tariffs and Trade (GATT); (2) the International Monetary Fund (IMF); and (3) the Organisation for Economic Co‐operation and Development (OECD) and its predecessor the Organisation for European Economic Co‐operation (OEEC). I use a standard “gravity” model of bilateral merchandise trade and a large panel dataset covering over 50 years and 175 countries. My results indicate that OECD membership has had a consistently large positive effect on trade, while accession to the GATT/WTO also increases trade.     

Imposing Capital Controls on Credit Unions: An Analysis of Regulatory Intervention in Australia

Abstract ** ** Résumé en fin d’article; Zusammenfassung am Ende des Artikels; resumen al fin del artículo.
: What impacts would minimum capital requirements have on mutual institutions lacking the ability to raise equity capital? Can the response of credit unions to capital controls be explained by internal member bonding? The imposition of capital controls on credit unions by the Australian Financial Institutions Commission is studied as a Box‐Tiao time series quasi‐experiment. Time series intervention and trend analyses are performed on a sample of 150 credit unions over the period 1987 to 1997, together with cross‐sectional regressions of the estimated responses. The results demonstrate that the capital controls had a significant impact on credit union behavior. Consistent with theoretical expectations, the response of individual credit unions is found to be a function of initial capital levels and internal member bonding.
