An analysis of wheat yield series from ten localities in Victoria was undertaken to investigate for independence of observations and to test for normality of the distributions. The conclusion was reached that Victorian wheat yield series are composed of random observations and form frequency distributions which display slight negative skewness. The situation may be different for other crops or for wheat in other areas. 相似文献

Two methods of evaluating (the net social benefits of the dairy herd-improvement scheme operated by the New South Wales Department of Agriculture are described. The first involves derivation of 'an input demand' function for the herd-recording aspect of the scheme and use of this function to estimate the economic surplus (net of both private and public costs) provided by the service. The second approach involves deriving a production function for milk from which it is possible to estimate the contribution herd-recording and artificial breeding have made to increasing milk yields per cow. Social benefits are shown to have been less than social costs for herd-recording, however dairy farmers have made net private gains. The herd-recording scheme has contained a regressive subsidy element. The production function approach show that artificial breeding and herd-recording were profitable complements in production. 相似文献

Performance feedback has significant potential to benefit employees in terms of individual and team performance. Moreover, effective performance feedback has the potential to enhance employee engagement, motivation, and job satisfaction. However, managers often are not comfortable giving performance feedback and such feedback, if improperly relayed, causes more harm than good. In this installment of HUMAN PERFORMANCE, we describe a shift from traditional weaknesses-based feedback (which relies on negative commentary focused on employees’ shortcomings) to the more constructive approach of strengths-based feedback (which relies on employee affirmation and encouragement). We explain why a strengths-based approach to performance feedback is superior to the weaknesses-centered approach, and offer nine research-based recommendations on how to deliver effective performance feedback employing a strengths-based method. 相似文献

‘Market failure’ is frequently offered as a justification for government intervention in the economy. Proponents of interventions can point to almost limitless examples of markets which do not meet all the criteria for Pareto optimality and argue that government taxation, subsidies or regulation can perfect them, maximising social welfare. But comparing market outcomes with an unattainable and unidentifiable ideal is not useful in a world of imperfect knowledge and government failure. It is better to compare market outcomes against realistic alternatives. Furthermore, even within the market failure paradigm, concepts such as ‘public goods’ and ‘negative externalities’ are routinely misunderstood and inconsistently applied. This leads to predictably poor policy outcomes. 相似文献

According to popular attitudes in Western democracies, the choice between right‐wing and left‐wing parties is a choice between socialism and unbridled free markets. In contrast, the cold and staid research of academia has frequently concluded that particular political parties do not really matter, as whichever party is elected will be closely tethered to the will of the median voter. This article considers the effects of the ideology of parties in power over the long run (1928–95) on economic freedom in subsequent periods. Right‐wing governments are found to have modest, positive effects on economic freedom, but the effects are not particularly robust. The findings here are consistent with others elsewhere, which conclude that there is minor, uneven evidence of an effect. Nonetheless, historically small effects may not be indicative of the future, should these effects be poorly indicative of today's tumultuous political landscape. 相似文献

We examine order type execution speed and costs for US equity traders. Marketable orders that execute slower exhibit lower execution costs. Those who remove liquidity faster and pay higher trading costs transact in smaller size, spread trading across more venues, take more liquidity, and are better informed. Nonmarketable limit orders that execute slower exhibit greater adverse selection; and larger, uninformed traders who concentrate their trading in fewer venues submit them. Our findings suggest that slowing down the trading process, when faster options exist, can benefit certain market participants who seek to cross the bid–ask spread. 相似文献
