Direct labour cost allocation for a multi-product hospital laundry

Article Abstract:

This paper discusses the application of correlation and regression methods to the analysis of productivity and allocation of costs in a laundry serving several hospitals, with several types of laundry being processed in the same production line. In particular, it is shown how the methods can be used to allocate the direct labour costs between the types of laundry. Analysis of residuals also permits investigation of temporal and product mix effects upon productivity. The regression paradox is discussed in relation to this problem, and it is shown that productivity is not a uniquely defined concept, because there is a difference between production being predicted from labour input and labour input being predicted from required production. Potential application of the model to other multi-product processes is discussed. (Reprinted by permission of the publisher.)

Multidivisional structure and productivity: the contingency of diversification strategy

Article Abstract:

A study of 65 firms was done to re-examine the relationship between corporate diversification and performance through the implementation of the multidivisional (M-form) structure strategy. A comparison was made on the impact of diversification on productivity before and after the corporate reorganization. The results revealed that there was a decline in productivity efficiency in vertically diversified firms while there was a productivity increase in related diversified companies. Meanwhile, unrelated diversified firms did not exhibit a significant increase in productivity.

Return earnings regressions and residual income: empirical evidence

Article Abstract:

An empirical study was conducted on the relationship between residual income and return earnings regressions. A regression model was developed which relaxes basic assumptions regarding the time series characteristics of residual income. Results showed that the incorporation of properties of a basic residual income generating process into research design can improve the modeling of relationships between returns and accounting earnings.
