Are public sector workers motivated by money?
No full textCarol Propper reviews recent evidence, drawn from a series of case studies that have been undertaken on individuals employed deep into the traditional public sector – in secondary education, government administration and public hospitals – which shows that incentives schemes can bring about increased productivity and that policy makers ignore the important of financial rewards at their peril
The Impact of Competition on Management Quality: Evidence from Public Hospitals
Full text linkWe analyze the causal impact of competition on managerial quality (and hospital performance). To address the endogeneity of market structure we analyze the English public hospital sector where entry and exit are controlled by the central government. Because closing hospitals in areas where the governing party is expecting a tight election race ("marginals") is rare due to the fear of electoral defeat, we can use political marginality as an instrumental variable for the number of hospitals in a geographical area. We find that higher competition is positively correlated with management quality, measured using a new survey tool. Adding a rival hospital increases management quality by 0.4 standard deviations and increases survival rates from emergency heart attacks by 8.8%. We confirm the validity of our IV strategy by conditioning on marginality in the hospital's own catchment area, thus identifying purely off the marginality of rival hospitals. This controls for "hidden policies" that could be used in marginal districts to improve hospital management. We also run placebo tests of marginality on schools, a public service where the central government has no formal influence on market structure.management, hospitals, competition, productivity
Modelling poverty by not modelling poverty: An application of a simultaneous hazards approach to the UK
Full text linkWe pursue an economic approach to analysing poverty. This requires a focus on the variables that individuals can influence, such as forming or dissolving a union or having children. We argue that this indirect approach to modelling poverty is the right way to bring economic tools to bear on the issue. In our implementation of this approach, we focus on endogenous demographic and employment transitions as the driving forces behind changes in poverty. We construct a dataset covering event histories over a long window and estimate five simultaneous hazards with unrestricted correlated heterogeneity. The model fits the demographic and poverty data reasonably well. We investigate the important parameters and processes for differences in individuals' poverty likelihood. Employment, and particularly employment of disadvantaged women with children, is important.poverty dynamics, poverty transitions, simultaneous hazards
Private Sector Employment Growth, 1998-2004: A Panel Analysis of British Workplaces
Full text linkUsing nationally representative panel data for British private sector workplaces this paper points to the importance of distinguishing between workplace and firm size when analysing employment growth, and finds that the factors associated with growth differ markedly between single independent establishments and those belonging to multi-site firms. Results also differ according to whether one adjusts for sample selection arising from workplace survival, and according to whether one distinguishes between growth per se and internal, organic employment growth. We find evidence at the plant level that is consistent with creative job destruction.employment growth, workplace survival, workplace age, workplace size, humancapital, sunk costs
Death by Market Power. Reform, Competition and Patient Outcomes in the National Health Service
Full text linkThe effect of competition on the quality of health care remains a contested issue. Most empirical estimates rely on inference from non experimental data. In contrast, this paper exploits a pro-competitive policy reform to provide estimates of the impact of competition on hospital outcomes. The English government introduced a policy in 2006 to promote competition between hospitals. Patients were given choice of location for hospital care and provided information on the quality and timeliness of care. Prices, previously negotiated between buyer and seller, were set centrally under a DRG type system. Using this policy to implement a difference-in-differences research design we estimate the impact of the introduction of competition on not only clinical outcomes but also productivity and expenditure. Our data set is large, containing information on approximately 68,000 discharges per year per hospital from 160 hospitals. We find that the effect of competition is to save lives without raising costs. Patients discharged from hospitals located in markets where competition was more feasible were less likely to die, had shorter length of stay and were treated at the same cost.competition, hospitals, quality
There Will Be Money
Full text linkA common belief among monetary theorists is that monetary equilibria are tenuous due to the intrinsic uselessness of fiat money (Wallace (1978)). In this article we argue that the tenuousness of monetary equilibria vanishes as soon as one introduces a small perturbation in an otherwise standard random matching model of money. Precisely, we show that the sheer belief that fiat money may become intrinsically useful, even if only in an almost unreachable state, might be enough to rule out nonmonetary equilibria. In a large region of parameters, agents' beliefs and behavior are completely determined by fundamentals.Fiat money, autarky, equilibrium selection
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
