A Generalised Model of Monopsony
提出一个简单的一般化模型，说明劳动力供给对单个雇主并非完全弹性，雇主可通过增加招聘支出来提高就业，并用英国数据证明招聘边际成本递增。
This article presents a general but very simple model in which the supply of labour to an individual employer is not infinitely elastic but the employer can also raise employment by increasing expenditure on recruitment. Using this, it is shown how that division between perfect competition and monopsony is whether there are diseconomies of scale in recruitment. Using a unique British data set containing information on both labour turnover costs and the number of recruits we present estimates that do suggest that there is an increasing marginal cost of recruitment.
