Many street‐level bureaucrats have the dual task of helping some clients, while sanctioning others. We develop a model of a street‐level bureaucracy, and we study the implications of its personnel policy on the self‐selection and allocation decisions of agents who differ in altruism towards clients. When bureaucrats are paid flat wages, they do not sanction, and the most altruistic types sort into bureaucracy. Pay‐for‐performance induces some bureaucrats to sanction, but it necessitates an increase in compensation, which can result in sorting from the top and bottom of the altruism distribution. We also explain why street‐level bureaucrats often experience an overload of clients.  相似文献

Data Aggregation Issues for Crop Yield Risk Analysis   总被引:1,自引:0,他引:1  
With increased emphasis on risk management in agriculture and a lack of disaggregated or farm‐level yield time series, decision makers are often faced with having to make adjustments to temporal yield risk measures obtained from readily available but aggregated yield data. This paper provides some empirical evidence on what type of aggregation bias to expect when measuring temporal yield risk using yield observations averaged across a region relative to yield risk estimated from quarter‐section yield time series in wheat. This study highlights some of the challenges faced when estimating aggregation distortions in measuring yield risk defined by temporal variance, especially given the nature of the empirical data set used. Cluster analysis, visual examination of relative frequency distributions and mapping of yield risk clusters suggest that using a readily available, aggregate temporal yield risk measure has the tendency to underestimate yield risk observed at the quarter‐section level and that clear, geographic yield risk boundaries do not exist in municipalities or across larger areas in this study. Further research on crops more risky than wheat appears promising. Avec un plus grand intéret sur la gestion du risk dans l'agriculture et un manque de données détaillees ou bien de collections de séries temporelles sur les rendements, les décideurs sont souvent tenus d'apporter des correctifs aux measures du risk obtenues a partir des données de rendements qui sont disponibles. Cet artcle apporte une preuve empirique du type de biais lie a l'agrégation qui peut être présent dans le calcul du risk de rendement temporel obtenu a partir de rendements moyens de blé observés au niveau régional en comparaison du risk de rendement qui est estimé a partir de données basées sur des quart‐de‐sections. Cette étude met en exergue quelques uns des obstacles qui se présentent dans l'estimation de distosions liées a l'aggrégation dans le calcul du risk de rendement défini par la variance temporelle, speciallement étant donne la charactère empirique des données utilisées. L'analyse de groupe, l'examen visual de la distribution des fréquences relatives, et la cartographie de classes de risk de rendement suggèrent que l'utilisation de la measure du risk de rendement basée sur des données disponibles de risk aggrège temporel a tendence a sousestimer le risk de rendement observe au niveau des quart‐de‐sections et qu'il n'y a pas de frontières de risk de rendement certaines, géographiques qui existent entre les municipalités ou bien a travers les zones plus larges examinées dans cette etude.  相似文献

The Economics of Anaerobic Digester Operation on a Minnesota Dairy Farm   总被引:1,自引:0,他引:1  
Anaerobic digesters for livestock operations are receiving attention for energy production and odor control. A farm-based digester went into operation in September 1999, on an 800-cow dairy farm in Minnesota. The goals of this paper are to analyze the contribution that a digester system can make to dairy farm profitability, and to demonstrate the impact of government and utility subsidies on profitability. Results indicate that the current selling price of electricity is not sufficient to justify building an anaerobic digester in most cases unless there is a subsidy or significant nonenergy market benefits.  相似文献

business is business! And business must grow –Dr. Seuss, The Lorax The paper investigates the agency argument that sales growth in firms with free cash flow (and without strong governance) is less profitable than sales growth for firms without free cash flow. It also tests whether strong governance conditions improve the performance of firms with free cash flow and/or limit the investments in unprofitable sales growth. Consistent with agency theory, firms with free cash flow gain less from sales growth than firms without free cash flow. But different governance conditions affect sales growth and performance in different ways. Having substantial management stock ownership mitigates the influence of free cash flow on performance, despite allowing higher sales growth. In contrast, outside blocks held by mutual funds reduce sales growth substantially, but does not increase performance from sales growth. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

The Internet is a growing information and communication channel for health- and diet-related issues. Keeping updated on the fruit- and vegetable-related (F&V) discourses among laypeople is important for health communicators in order to promote F&V consumption through tailored health messages. The aim of the present study was to identify F&V-related discourses in weblogs that were maintained, obviously, to influence diet. A theoretically chosen sample of weblogs were analysed applying critical discourse analysis. The analysis showed three partly overlapping F&V-related discourses: (1) normative consumption with a focus on single nutrients and physiological mechanisms; (2) authentic consumption with a desire for naturalness; and (3) altruistic consumption where ethical responsibilities are enhanced. Bloggers have clear perceptions on ideal F&V consumption, but it is a challenge for the reader to make a synthesis of the discourses presented. Filtering contradictory instructions requires health literacy, which may need more support from dietetic professionals.  相似文献

Spatial Yield Risk Across Region, Crop and Aggregation Method   总被引:1,自引:0,他引:1  
A researcher interested in crop yield risk analysis often has to contend with a lack of field- or farm-level data. While spatially aggregated yield data are often readily available from various agencies, aggregation distortions for farm-level analysis may exist. This paper addresses how much aggregation distortion might be expected and whether findings are robust across wheat, canola and flax grown in two central Canadian production regions, differing mainly by rainfall, frost-free growing days and soil type. Using Manitoba Crop Insurance Corporation data from 1980 to 1990, this research, regardless of crop or region analyzed, indicates that (i) spatial patterns in risk are absent; (ii) use of aggregate data overwhelmingly under-estimates field-level yield risk; and (iii) use of a relative risk measure compared to an absolute risk measure leads to slightly less aggregation distortion. Analysts interested in conducting farm-level analysis using aggregate data are offered a range of adjustment factors to adjust for potential bias.  相似文献

Rumelt’s (1991) widely cited paper presents estimates of the relative influence of industry, corporate, business unit, and other influences on business unit profitability. He finds corporations explain almost none of the variability in business unit profitability. Using a simultaneous equation model, we provide alternative estimates of the influence of industry and corporation on business unit performance. We find that both corporations and industries influence business unit profitability but corporations have the larger influence. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Markets for dairy quality hay have emerged as dairy farms purchase more feed off the farm. Previous research on hay markets used proxies for quality since objective measures of quality were unavailable. A hedonic pricing model incorporating direct measures of quality (moisture, crude protein, and relative feed value (RFV)), proxies (cutting), and bale-type variables was estimated using data from a hay auction. Large round and square bales and medium round bales were discounted relative to small square bales. The implicit price for RFV was $0.55/ton in 2001–02.  相似文献

Multifunctional land use has become a widely supported pathway for Europe's countryside. Brussels and the national governments stimulate farmers to integrate primary production with non-agricultural practices from which they can also benefit. In favour of this development different stakeholders are encouraged to collaborate to produce the so-called farmer-managed public goods. This paper explores critical success factors for the production and maintenance of these public goods. In two Dutch case study regions we show a chronology of major events from 1975 leading to a shift from primary agricultural production towards a successful multifunctional land use. We evaluated which critical success factors crucial for managing public goods manifest themselves in our case study regions. Besides six critical success factors described in literature (Property rights, Asymmetric information, Administrative complexity, Governance, Time lags and Market structure) four other factors appear to be crucial in governing farmer-managed public goods: (1) establishing a system of rewards; (2) a mix of governance forms; (3) visionary leadership with networks in both the public and the private sectors and (4) time for new ideas to mature and to build commitment among the actors.  相似文献
