The responses of workers and their employers to the onset of work-limiting health impairments were investigated using data from the new Health and Retirement Study. The results indicate that many workers who suffer from health limitations are directly accommodated by their employers, and that those those who do not receive direct accommodation frequently adapt to their limitations by altering t...

Intel’s SpeedStep and AMD’s PowerNOW technologies allow the Windows XP operating system to dynamically change the speed of the processor to prolong battery life. In this setting, the operating system must not only have a job selection policy to determine which job to run, but also a speed scaling policy to determine the speed at which the job will be run. We give an online speed scaling algorit...

Using data from the 1990 and 1993 Survey of Income and Program Participation, this paper attempts to examine how job mobility among disabled workers changed in the early 1990s and to disentangle the American with Disabilities Act (ADA) effects from the macroeconomic effects on this change of job mobility. This paper finds that the job mobility among disabled workers improved but there is no evi...

In this paper we consider the problem of scheduling n jobs such that makespan is minimized. It is assumed that the jobs can be divided into K job-classes and that the change-over time between two consecutive jobs depends on the job-classes to which the two jobs belong. In this setting, we discuss the one machine scheduling problem with arbitrary processing times and the parallel machines schedu...

In Japan, non-regular employment, such as part-time and temporary work, has increased as a proportion of the workforce in recent years. This paper examines whether the expansion of temporary employment has caused an increased perception of job insecurity among existing workers. I exploit the temporary staffing deregulation of 2004, which allowed temporary agency staffing for production line wor...

C jobs is often the primary goal of economic development policy. To help target their job creation efforts, policymakers generally examine net changes in the official employment figures. But relying solely on net changes can often hide important gross changes that influence the dynamics of job creation and destruction. Knowing where jobs are currently being created and destroyed in an economy c...
