This study investigates the use of hedonic pricing to identify the value of relevant production and type traits for dairy bulls in Alberta. A hedonic pricing model is estimated that considers semen price as a function of individual production and longevily characteristics for a sample of Holstein bulls. The results suggest that the most important characteristics used by Alberta daity producers in valuing dairy bulls are milk volume, protein and fat content, general conformation, body capacity and the popularity of the bull. For a given set of such characteristics, the probability that the bull's semen may be in short supply does not significantly affect the value. This methodology may be used to establish a method of forecasting semen prices for newly proven bulls. The valuation procedure may be easily updated and adjusted as producers'breeding objectives change over time because of the changing economic environment. The results of this analysis suggest that hedonic pricing may be a better method of placing a value on production and type characteristics for dairy bulls than the Lifetime Profit Index currently being used by the Canadian dairy industry. 相似文献

It has been suggested that Mexican investors were the “front-runners” in the peso crisis of December 1994, turning pessimistic before international investors. Different expectations about their own economy, perhaps due to asymmetric information, prompted Mexican investors to be the first ones to leave the country. This paper investigates whether data from three Mexican country funds provide evidence that supports the “divergent expectations” hypothesis. We find that, right before the devaluation, Mexican fund Net Asset Values (mainly driven by Mexican investors) dropped first and/or faster than Mexican country fund prices (mainly driven by foreign investors). Moreover, we find that Mexican NAVs tend to Granger-cause the country fund prices. This suggests that causality, in some sense, flows from the Mexico City investor community to the Wall Street investor community. 相似文献

Summary. We investigate, in an experimental setting, the behavior of single decision makers who at discrete time intervals over an
“infinite” horizon may choose one action from a set of possible actions where this set is constant over time, i.e. a bandit
problem. Two bandit environments are examined, one in which the predicted behavior should always be myopic (the two-armed
bandit) and the other in which the predicted behavior should never be myopic (the one-armed bandit). We also investigate the
comparative static predictions as the underlying parameters of the bandit environments are changed. The aggregate results
show that the behavior in the two bandit environments are quantitatively different and in the direction of the theoretical
predictions.

Previous closed‐end country fund research concludes that returns behave more like the U.S. market than like their target markets. We argue this finding may be biased by model misspecification and inappropriate estimation techniques. We propose a single‐equation model containing five hypothesized factors of fund returns. We estimate this model for nineteen pooled seasoned funds using a time‐series cross‐section regression that corrects for two types of autocorrelation. We show that returns are strongly related to target markets. Returns are also related to changes in discounts, exchange rates, and other countries' markets, but are only weakly related to the U.S. market. JEL classification: G10, G12 相似文献

Short-Term Persistence in Mutual Fund Performance 总被引:1,自引:0,他引:1
We estimate parameters of standard stock selection and markettiming models using daily mutual fund returns and quarterlymeasurement periods. We then rank funds quarterly by abnormalreturn and measure the performance of each decile the followingquarter. The average abnormal return of the top decile in thepost-ranking quarter is 39 basis points. The post-ranking abnormalreturn disappears when funds are evaluated over longer periods.These results suggest that superior performance is a short-livedphenomenon that is observable only when funds are evaluatedseveral times a year. 相似文献

This study examines the relationship among perceived strategic uncertainty (PSU), environmental scanning, and the information sources used by owner–managers of a sample of 153 small high-technology manufacturing firms. The results suggest that increased scanning activities are associated with high levels of PSU. Perhaps most importantly, the results also suggest that owner–managers of younger firms respond to uncertainty differently than their counterparts in more mature firms. Specifically, owner–managers of younger firms appear to respond to higher PSU by relying more heavily on personal and external information sources. Owner–managers of older firms, on the other hand, rely more heavily on internal and impersonal information sources to address environmental uncertainty. 相似文献

This paper applies to the health sector a method of projectanalysis advocated recently by Devarajan, Squire, and Suthiwart-Narueput.A health project evaluation should establish a firm justificationfor public involvement; establish the counterfactualwhatwould happen with and without the project; and determine thefiscal effect of the project and the appropriate levels of feesin conjunction with project evaluation. The evaluation shouldalso acknowledge the fungibility of project resources and examinethe incentives both for high-level public servants to shiftgovernment resources away from project-funded activities tothose that have not been evaluated and for lower-level contractorsand civil servants to provide good or bad service. Market failuresin health services and insurance markets should serve as a startingpoint for economic analysis, not as a reason to ignore economicsin health projects. Project outputs should be predicted aftertaking into account the reaction of consumers and providersin the private sector as well as market structures of supply,demand, and equilibrium for health services. 相似文献

This article adds to the information base concerning the applicability of mean–Gini stochastic efficiency analysis in agriculture. The mean–Gini efficient set of decisions is characterized rigorously in terms of its corresponding absolute risk aversion. In an empirical analysis, the mean–Gini efficient set of decisions is derived for four studies from the literature and compared to the second degree stochastic dominance efficient set. An alternative quantitative measure of risk aversion is used to gain insight in a visceral sense to the risk preferences associated with mean–Gini efficient decisions. 相似文献

I study a simple, widely applicable approach to handling the initial conditions problem in dynamic, nonlinear unobserved effects models. Rather than attempting to obtain the joint distribution of all outcomes of the endogenous variables, I propose finding the distribution conditional on the initial value (and the observed history of strictly exogenous explanatory variables). The approach is flexible, and results in simple estimation strategies for at least three leading dynamic, nonlinear models: probit, Tobit and Poisson regression. I treat the general problem of estimating average partial effects, and show that simple estimators exist for important special cases. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献
