We analyse the technical efficiency of dairy farms in Schleswig‐Holstein that took part in the European Farm Credit Programme over the period 1987 to 1994. One goal of this programme is to increase the productivity of farms. We test whether participants show higher technical efficiency. We utilise a stochastic frontier model that allows for heteroscedasticity and estimation of determinants of technical inefficiency. Statistical tests indicate dominance of this model over alternative specifications. On average, we observe a high level of technical efficiency between 1987–94, but participation in the programme has rather led to a slight decrease. Thus, the programme seems to have failed to increase the competitiveness of farms. 相似文献

Framing Effects in Stock Market Forecasts: The Difference Between Asking for Prices and Asking for Returns 总被引:2,自引:0,他引:2
Studies analyzing return expectations of financial market participantslike fund managers, CFOs or individual investors are highlyinfluential in academia and practice. We argue and show thatthe results in these surveys above are easily influenced bythe elicitation mode of return expectations. Surveys that askfor future stock price levels are more likely to produce meanreverting expectations than surveys that directly ask for futurereturns. Furthermore, we conduct a questionnaire study thatexplicitly analyzes whether the specific elicitation mode affectsreturn expectations in the above direction. In our study, subjectswere asked to state mean forecasts for seven time series. Usinga between subject design, one half of the subjects was askedto state future price levels, the other group was directly askedfor returns. We observe a highly significant framing effect.For upward sloping time series, the return forecasts statedby investors in the return forecast mode are significantly higherthan those derived for investors in the price forecast mode.For downward sloping time series, the return forecasts givenby investors in the return forecast mode are significantly lowerthan those derived for investors in the price forecast mode.We argue that this finding is consistent with behavioral theoriesof investor expectation formation based on the representativenessheuristic. 相似文献

This study investigates the pricing of electricity futures at the European Energy Exchange (EEX) over the period 2002 through 2004. To calculate theoretical contract values, the reduced‐form models of J. J. Lucia and E. S. Schwartz (2002) are used, and a thorough empirical analysis by means of an out‐of‐sample test is conducted for both one‐ and two‐factor models, incorporating a constant non‐zero price of risk. Although the models are proven to capture all basic spot market characteristics and provide an accurate in‐the‐sample fit to observed futures prices, the forecasting performance is subject to biases. For instance, it was found that the relative mispricing depends on both the spot price level and the remaining time‐to‐maturity of the futures contracts. © 2007 Wiley Periodicals, Inc.

Banks can learn valuable lessons from the bundling models developed successfully in other industries. Bundling core banking products with additional services allows banks to differentiate themselves in a generally homogenous sector. Bundling also increases sales across product areas and aids customer lock-in. This paper provides an overview of how to create attractive and profitable bundles through a systematic, multi-stage approach to customer segmentation, targeting and product positioning. 相似文献

An owner‐manager can delegate two tasks to an agent. A time constraint prevents him from completing both tasks at first‐best levels. He can (a) perform both tasks personally to the extent possible, (b) delegate one task to an agent, or (c) delegate both tasks. Agency costs arise from a congruity problem, a double moral hazard problem, and a risk and incentive trade‐off. Delegation becomes more favorable the stronger the time constraint. Once delegation is preferred, the optimal extent of delegation depends on the relation of sensitivity to productivity ratios in both tasks. Agency costs not necessarily increase in delegation level. 相似文献

This paper reports on a survey of regulatory impact assessment (RIA) in 16 developing and emerging economies. RIA was playing an increasing role in these countries: eight had introduced RIA in the past 10 years; one had recently redesigned its existing RIA system; another had a long-standing RIA system in place. However, RIA was at an early stage of development in the majority of cases and six countries did not practise RIA. 相似文献

Do Lower Caseloads Improve the Performance of Public Employment Services? New Evidence from German Employment Offices 下载免费PDF全文
Jens Hainmueller Barbara Hofmann Gerhard Krug† Katja Wolf 《The Scandinavian journal of economics》2016,118(4):941-974
The caseworker‐to‐clients ratio is an important, but understudied, policy parameter that affects both the quality and cost of public employment services that help job seekers find employment. We exploit a large‐scale pilot by Germany's employment agency, which hired 490 additional caseworkers in 14 of its 779 offices. We find that lowering caseloads caused a decrease in the rate and duration of local unemployment as well as a higher re‐employment rate. Disentangling the mechanisms that contributed to this improvement, we find that offices with lowered caseloads increased monitoring and imposed more sanctions but also intensified search efforts and registered additional vacancies. 相似文献
