Employer-Provided Training and Tenure-Earnings   总被引:1,自引:0,他引:1  
This article examines the tenure-earnings profiles and suggests that the more training is provided to the individual by the employer, the steeper is the tenure profile of earnings. The provision of training by the employer is modelled as endogenous and subject to choice decisions using an ordered probit model corresponding to three levels of training. The earnings equations of three groups of employees are then adjusted for potential effects of bias due to selectivity by using Lee's procedure, and heterogeneity bias using the Altonji and Shakotko instrumental variable procedure.  相似文献

A future-oriented participatory procedure on the basis of the Delphi method was developed and empirically tested a first time with the goal to improve the shaping of technological developments. The technology under study here was micro-electronics or rather their relationship with labor and the test took place in NorthRhine-Westphalia.Today problems exist in all walks of life. There is a lot of talk about today's problems as if they were new, though one has heard similar arguments throughout history. How do we assess if we are really in danger of bringing the world to an end? Although this danger appears real, it would not be the first time in history that people have thought and felt like this--However, one thing that is new are the consequences of modern sciences and technology, which are not suited to given social and environmental requirements. They have given rise to questions concerning the quality of the decision-makers. The questioning of many of these decisions has increased for some time and is now getting more and more specific, with a demand for quality and information rather than managerial skills and competitiveness from the decision-makers. The term ‘decision-maker’ describes those who determine the application of technology, science and technical equipment which has either existed for a long time already or has recently been developed.--It is not easy to change the structures and processes of decision-making so that new structures and processes will be more suited to social and environmental requirements. We have tested our ideas as to how this could be done, in an empirical project. Although we called it ‘Project NRW-2000’, it would probably be better described as an experiment.--We persuaded 90 ordinary people to participate in this project as ‘experts on daily life and work’. This group was asked to work in six regional sub-groups and discuss, with reference to three given normative societal scenarios for the year 2020, the relationship between microelectronics and labour markets of the year 2020, on the basis of a participatory Delphi procedure. Before we elaborate on the concept of our project in Section 3, we would like to outline it in terms of the mainstream of the sociology of technology as well as with research on ‘acceptance’ in Section 1. In Section 2 we will briefly illustrate the framework of the research programme ‘Socially Oriented Shaping of Technology’ of the state of Northrhine-Westphalia, which funded our research project. Section 4 particularly deals with the participatory elements of our project, while Section 5 is devoted to the development of the scenarios. Section 6 sums up the results of the ‘scenario-construction’. Regarding specific elements, we restrict ourselves to topics concerning technology, labour, and the relationship between women workers/employees and technology. As a final outlook we deal with the political implications of our approach. All that is left is to remind our readers that we regard this project as a first application or experiment within our overall approach.  相似文献
