In this article we show that technological parameter estimates obtained by estimating a cost function that is derivable as the dual of a production function can be biased and inconsistent if the stochastic structure of the model arises from certain types of behavioural assumptions made about...

Using Danish register and survey data, we examine the effect of a national graded return-to-work program on the probability of sick-listed workers returning to regular working hours. During program participation, the worker receives the normal hourly wage for the hours worked and sickness...

Wages in traditional agrarian societies are often observed to be above reservation wages even in the slack season when markets are in a state of excess labour supply. Models of non-cooperative wage setting by landlords which explicitly take account of the costs of supervising hired labour and...

A new method for estimating a relative scale function is derived which does not require the specification or estimation of the firm's cost function. The method is applied to a panel of Canadian trust companies for the years 1985–1988. Results show that the industry scale function is convex...

An econometric model of Canada's five largest banks is estimated using time series data from 1976 to 1996. The principal findings are that chartered bank technology is characterized by increasing returns to scale. Scale efficiency is sufficiently large to offset the consequences of reduced...
