Trade-off between Quality and Cost

This paper proposed a new model that takes both quality and cost into account. This model is a natural extension of the classical Taguchi quality model where only quality is controlled. This paper also gives a number of numerical examples for illustration.

Latent factor structures affecting the occupational profile construct of the training needs analysis scale

This study evaluates the latent factor structure of the occupational profile construct of the training needs analysis (TNA) scale proposed by Hicks, Hennessy and Barwell (1996). Data were collected from 72 Australian nurses. Principal component analysis and multi-dimensional scaling methods were employed to delineate a five-factor model. This study demonstrates a good fit of data as opposed to asymmetrical disposition of factor structures as promulgated by previous studies. This research confirms the original latent factor structures; however, validation using a confirmatory framework to analyse the TNA scale is required in future. This study suggests some practical implications for human resource managers.

Matching,human capital,and the covariance structure of earnings

This paper tests the theory of job matching and the theory of human capital by examining the covariance structure of residuals from a typical Mincer log earnings equation using methods of moments techniques. Job matching theory predicts that we should observe an eventual decrease in the contribution of the job-match component in the residual variance as workers acquire tenure on the job. This prediction is mildly supported by the data. On the other hand, human capital theory predicts a trade-off between job-specific intercept and slope parameters. This prediction, which is not shared by the theory of matching, is strongly supported by the data. This is especially true for men with at least a high school degree.     

“外生公共品”内生供给与小农社会转型

传统微观经济学认为公共品的边际福利效应总是正的,很多实证结论证实了这一点。但是,在转型过程中,落后农业区出现了公共品内生供给增加,对福利的增加影响不显著,甚至有副作用。本文提出一种理论解释模型,认为落后农业区存在不完全可调整的消费约束线,使经济无法实现新的均衡,引致了负面的福利效应。我们用落后农业区的样本检验,得出公共品的转移支付可以提高福利,而当地自筹财政收入对福利影响总是不显著的。所以我们认为加大对落后农业区的转移支付对小农社会转型是必要的。

Employee bonding and turnover efficiency

This study explores how bonding contracts improve employee attraction and retention. These bonds are payment schemes tied to employment duration, such as the vesting of pensions and stock options. This study presents an employee turnover model in which only the worker knows their taste for their current job. This taste gives the current employer monopsonistic power, resulting in deadweight loss from excessive turnover. Bonding contracts serve as a commitment device for future wages and eliminate such deadweight loss, but only when the roles of bondholders and wage setters are separate. Firms that do this are more competitive to new hires. This model offers several empirical findings regarding a variety of common bonding practices.

A Spatial Analysis of Mental Healthcare in Texas

This paper discusses competing-destinations formulation of the gravity model for the flows of patients from their residential areas to health supplier regions. This approach explicitly acknowledges the interdependence of the patient between a set of alternative health supplier regions. This competing-destinations-based approach may be implemented as a probabilistic demand function or conditional logit model, with a Poisson outcome. A Texas-based case study of residential areas and State Mental Hospitals (SMHs) is presented. The results of the estimation do not lend support to the presence of scale effects in SMHs due to the size of population. This result, combined with the negative effect of average length of stay and with the positive effect of the provision of forensic services on patient flows, highlights the problem of caseload growth in SMHs.

The efficiency of training and hiring with intrafirm bargaining

This paper demonstrates that firms hire and train workers efficiently in a matching and intrafirm bargaining economy when the Hosios condition holds and returns to scale are constant. This conclusion stands in contrast to the prevailing view that training costs are a source of inefficiency in imperfect labor markets. The efficiency of the competitive economy relies on the ability of large firms to take into account the negative impact of the training rate on the wages negotiated inside the firm through intrafirm bargaining: untrained workers accept a wage reduction in compensation for potential training that is accessible only following employment. This intrafirm bargaining process solves efficiency problems associated with training costs that would otherwise lead to inefficient hiring and training decisions. This conclusion holds true for both specific and general human capital.     

A progress report: The ‘quality of life’ in a method of integrated planning: Aspects of an Italian research project, ‘Progetto Quadro’

This paper describes the main concepts and approaches of a method of integrated planning developed in Italy. This work, still in the research phase, is sponsored by the Italian government agency responsible for economic planning.

Formally entitled ‘Progetto Quadro’, the project involves construction of a reference framework composed of a set of highly disaggregated socio-economic accounts. This includes a resource-use analysis of structural and functional interdependencies of the economic system and of its operation with regard to a societally inspired program-structure.
