This paper measures an important component of the research output of economics and econometrics teaching departments, namely, the number of pages published during the period 1988-93, in journals listed by the Journal of Economic Literature. Based on page counts it is found that department rankings are similar over a broad range of journal groupings. It is also found that the median numbers of pages published by each of the groups of senior lecturers, associate professors and professors are quite small, indicating that within these groups research output is highly concentrated among a few active publishers. 相似文献

文章针对我国目前主要农产品出现的供需“缺口”特殊现象,选取1982—2006年的样本数据进行实证检验,探求农产品需求、供给的影响因素及其之间的数量关系,并从需求与供给视角分析价格变化方向和影响程度,在此基础上建立农产品价格动态波动的理论模型。实证表明:我国主要农产品,如粮食、猪肉与棉花等的供给存在“二元”特征,导致农产品供给反应具有粘滞性;需求与价格关系因产品种类而异;农产品供给与需求对价格的影响符合经济规律。通过实证与理论研究,最后提出维持农产品供求均衡的政策建议。 相似文献
