Decomposing hospital productivity changes, 1985–1988: A nonparametric Malmquist approach

Annual data on U.S. hospitals from 1985–1988 are evaluated by ownership type—profit, nonprofit, state and local government, and U.S. Department of Veterans Affairs (VA)—for changes in hospital productivity over time. Distance functions are used to measure Malmquist indices of productivity change, which are then decomposed into indices of efficiency change and technology change. In contrast to previous studies using this approach, we allow for variable returns to scale and use both input and output orientations. We find that changes in technology dominate changes in inefficiency in determining changes in productivity.     

Citizens’ Europe: Crowded out by economic focus

Over the last ten years the European unification project seemed to rely overwhelmingly on progress in economic terms. The most prominent achievements — the Single Market, the harmonisation of market regulation, the euro — were all driven by an economic rationale. However, attempts to rescue Europe from the ongoing financial crisis call for mutual support and solidarity, concepts that can hardly be derived from pure economic reasoning. This leads to an important question that has been too long neglected: what is the political and civic motivation for a united Europe? Besides a great desire to stabilise peace in Europe, the origins of the unification activities also included mutual interest in language, culture, habits and people in neighbouring countries. Has this been abandoned in favour of a purely economic vision? Or are the economic arguments merely the easiest to promote to the European population? What message does this send in times of mistrust in markets and dim economic prospects for the eurozone? Can a political, cultural and civic European spirit still be reinvigorated, and if so, how?     

Board Pay and the Separation of Ownership from Control in U.K. SMEs

This paper examines Board pay for a sample of 571 U.K. SMEs from 1991 to 1995. Approximately half of the sample were closely-held (i.e., owner-managed) firms which allowed empirical testing of models of the relationship between Board pay and ownership from control characteristics. Consistent with their need to align shareholder and manager incentives, the results indicate that the change in nonclosely-held SME Board pay is significantly related to both external market pay comparisons and “benchmark” profits. This contrasts with the empirical results for the closely-held firms where Board pay awards are typically highly sensitive to current total profits but wholly unrelated to external market pay levels.     

Pattern of childhood falls in a low-income setting: a cross-sectional study in Dar es Salaam

The objective was to determine patterns and circumstances of childhood falls in a low-income setting in Dar es Salaam, Tanzania. This cross sectional study is based on a household survey conducted in July 2009. A total of 3927 children up to age 18 from 1928 households in 15 sampled wards were surveyed through a structured questionnaire. The current study includes information regarding fall occurrence, socio-demographic and economic factors. Data were analysed using chi-square, t-test and logistic regression. Male children had 42% higher odds of falls compared to females, and rural residents had more than two times higher odds compared to urban residents. Falls occurred three times more among age group 1-4 and two times more among age group 5-9 compared to those between 15 and 18 years. Most falls occurred outdoors (62%) while playing (51%) with boys being over-represented. Females and children aged 1-4 years fell more from stairs whereas most infants fell from furniture. Male gender, younger age groups and rural residence were significant factors for fall injuries. The circumstances in which these falls occur also differ significantly. Intervention efforts should emphasise these patterns.     

High Natural Gas Prices in California, 2000–2001: Causes and Lessons

The market prices of natural gas delivered to California rose to unprecedented levels in late 2000 and remained well above levels elsewhere in the country until the summer of 2001 (Figure 1). In addition to the direct impact on natural gas consumers, the high natural gas prices were also a major cause of the high electricity costs suffered by California and other western states in the June 2000–June 2001 period. This paper describes the market and regulatory circumstances that led to such high prices over such an extended period. Lessons are drawn from this experience for other regions wishing to understand and avoid such problems in natural gas markets.     

An Empirical Investigation of Trade Credit Demand

This paper investigates the motivations for a firm's demand for trade credit. Demand for credit is modelled as a function of transaction costs motivations, financing motivations, operational considerations, seller compliance issues and supplier marketing, whilst controlling for the firm's business environment and for firm characteristics such as size and industry. This paper builds on previous studies by considering a wider range of factors that can affect trade credit demand holistically on a single sample. It appears that the use of trade credit is widespread, and that it is generally perceived as an important short term financing option, although the availability of trade credit is not a major influence on supplier choice. The level of a firm's trade credit demand is found to be significantly influenced by transaction costs, financing, operational issues, marketing activities by suppliers, the firm's investment in trade debtors and firm size.     

Nondiscretionary residential water use: the impact of habits and water‐efficient technologies

Several studies published in the last few decades have demonstrated a low price‐elasticity for residential water use. In particular, it has been shown that there is a quantity of water demanded that remains constant regardless of prices and other economic factors. In this research, we characterise residential water demand based on a Stone‐Geary utility function. This specification is not only theory‐compatible but can also explicitly model a minimum level of consumption not dependent on prices or income. This is described as minimum threshold or nondiscretionary water use. Additionally, the Stone‐Geary framework is used to model the subsistence level of water consumption that is dependent on the temporal evolution of consumer habits and stock of physical capital. The main aim of this study is to analyse the impact of water‐saving habits and water‐efficient technologies on residential water demand, while additionally focusing attention on nondiscretionary uses. This is informed by an empirical application using data from a survey conducted among residents of Brisbane City Council, Australia. The results will be especially useful in the design of water tariffs and other water‐saving policies.     

A Bug Is a Bug Is a Bug: Symbolic Responses to Contingent Valuation Questions about Forest Pest control programs?

Symbolic responses are one of many issues attending contingent valuation studies. The problem is that many objects that are the subject of contingent valuation surveys can act as symbols for larger issues. In this paper, we want to compare the attitudes of residents of five communities with two different forest pests, jack pine budworm and gypsy moth. Jack pine budworm affects commercially important forests in Canada, while gypsy moth generally affects recreational areas and has less commercial significance. All of the respondents were asked about both insects; however, not all of the communities had direct experience with both insects. The purpose is to examine whether respondents would differentiate their willingness to pay for control mechanisms between these different defoliators. The implication is that all bugs are alike and generally noxious, a notion that would not necessarily sit well with resource managers who have to deal with insect outbreaks. Respondents did not differentiate strongly between insect control programs that would impact their community and those that would not. While not conclusive, the results do suggest symbolic responses to this particular issue. This is further evidence that willingness-to-pay results from contingent valuation studies need to be cautiously interpreted as pseudo market values.
