This theory of persistence in structural unemployment has been referred to as an example of path dependence or "hysteresis." Much technological unemployment, caused by the replacement of workers by machines might be counted as structural unemployment. Alternatively, technological unemployment might refer to the way in which steady increases in labour productivity mean that fewer workers are needed to produce the same level of output every year. The fact that aggregate demand can be raised to deal with the problem suggests that the problem is instead one of cyclical unemployment. As indicated by Okuns law, the demand side must grow sufficiently quickly to absorb not only the growing labour force but also the workers who are made redundant by the increased labour productivity. Seasonal unemployment may be seen as a kind of structural unemployment since it is linked to certain kinds of jobs (construction and migratory farm work). The most-cited official unemployment measures erase this kind of unemployment from the statistics using "seasonal adjustment" techniques. That results in substantial and permanent structural unemployment. Frictional unemployment
Frictional unemployment is the time period between jobs in which a worker searches for or transitions from one job to another. It is sometimes called search unemployment and can be voluntary, based on the circumstances of the unemployed individual. Frictional unemployment exists because both jobs and workers are heterogeneous, and a mismatch can result between the characteristics of supply and demand. Such a mismatch can be related to skills, payment, work-time, location, seasonal industries, attitude, taste, and a multitude of other factors.
Availability
Since 2009, lansoprazole has been available over the counter (OTC) in the U.S. as Prevacid 24HR and as Lansoprazole 24HR. In Australia, it is marketed by Pfizer as Zoton. Research
In vitro experiments have shown that lansoprazole binds to the pathogenic form of tau protein. As of 2015 laboratory studies were underway on analogs of lansoprazole to explore their use as potential PET imaging agents for diagnosing tauopathies including Alzheimers disease. References
