Many economists contend that technology is the primary driver of the increase in wage inequality since the late 1. El Libro De Los Secretos Osho Pdf Gratis.

A more recent SBTC explanation focuses on computerizations role in increasing employment in both higher wage and lower wage occupations, resulting in job polarization. This paper contends that current SBTC modelssuch as the education focused canonical model and the more recent tasks framework or job polarization approach mentioned abovedo not adequately account for key wage patterns namely, rising wage inequality over the last three decades.

Technological and skill deficiency explanations of wage inequality have failed to explain key wage patterns over the last three decades, including the 2. The early version of the skill biased technological change SBTC explanation of wage inequality posited a race between technology and education where education levels failed to keep up with technology driven increases in skill requirements, resulting in relatively higher wages for more educated groups, which in turn fueled wage inequality Katz and Murphy 1.

However, the scholars associated with this early, and still widely discussed, explanation highlight that it has failed to explain wage trends in the 1. Autor, Katz, and Kearney 2. Acemoglu and Autor 2. This motivated a new technology based explanation formally called the tasks framework focused on computerizations impact on occupational employment trends and the resulting job polarization the claim that occupational employment grew relatively strongly at the top and bottom of the wage scale but eroded in the middle Autor, Levy, and Murnane 2. Autor, Katz, and Kearney 2. Acemoglu and Autor 2. Autor 2. 01. 0. We demonstrate that this newer versionthe task framework, or job polarization analysisfails to explain the key wage patterns in the 1. We conclude that there is no currently available technology based story that can adequately explain the wage trends of the last three decades. History shows that middle wage occupations have shrunk and higher wage occupations have expanded since the 1. This has not driven any changed pattern of wage trends. We demonstrate that key aspects of job polarization have been taking place since at least 1. We label this occupational upgrading since it primarily consists of shrinkage in relative employment in middle wage occupations and a corresponding expansion of employment in higher wage occupations. Lower wage occupations have remained a small less than 1. Occupational upgrading has occurred in decades with both rising and falling wage inequality and in decades with both rising and falling median wages, indicating that occupational employment patterns, by themselves, cannot explain the salient wage trends. Evidence for job polarization is weak. We use the Current Population Survey to replicate existing findings on job polarization, which are all based on decennial census data. E Paper Technology Seminar Report On Electric Traction' title='E Paper Technology Seminar Report On Electric Traction' />Job polarization is said to exist when there is a U shaped plot in changes in occupational employment against the initial occupational wage level, indicating employment expansion among high and low wage occupations relative to middle wage occupations. As shown in Figure E explained later in the paper but introduced here, in important cases, these plots do not take the posited U shape. More importantly, in all cases the lines traced out fit the data very poorly, obscuring large variations in employment growth across occupational wage levels. There was no occupational job polarization in the 2. In the 2. 00. 0s, relative employment expanded in lower wage occupations, but was flat at both the middle and the top of the occupational wage distribution. The lack of overall job polarization in the 2. American Community Survey data provided by proponents of the tasks frameworkjob polarization perspective Autor 2. Acemoglu and Autor 2. Current Population Survey. Thus, the standard techniques applied to the data for the 2. This leaves the job polarization story, at best, as an account of wage inequality in the 1. It certainly calls into question whether it should be a description of current labor market trends and the basis of current policy decisions. Occupational employment trends do not drive wage patterns or wage inequality. We demonstrate that the evidence does not support the key causal links between technology driven changes in tasks and occupational employment patterns and wage inequality that are at the core of the tasks framework and job polarization story. Proponents of job polarization as a determinant of wage polarization have, for the most part, only provided circumstantial evidence both trends occurred at the same time. The causal story of the tasks framework is that technology i. These changes in occupational employment patterns are said to drive changes in overall wage patterns, raising wages at the top and bottom relative to the middle. However, the intermediate step in this story must be that occupational employment trends change the occupational wage structure, raising relative wages for occupations with expanding employment shares and vice versa. We demonstrate that there is little or no connection between decadal changes in occupational employment shares and occupational wage growth, and little or no connection between decadal changes in occupational wages and overall wages. Changes within occupations greatly dominate changes across occupations so that the much focused on occupational trends, by themselves, provide few insights. Occupations have become less, not more, important determinants of wage patterns. The tasks framework suggests that differences in returns to occupations are an increasingly important determinant of wage dispersion. Using the CPS, we do not find this to be the case. We find that a large and increasing share of the rise in wage inequality in recent decades as measured by the increase in the variance of wages occurred within detailed occupations. Furthermore, using Di. Nardo, Fortin, and Lemieuxs reweighting procedure, we do not find that occupations consistently explain a rising share of the change in upper tail and lower tail inequality for either men or women. An expanded demand for low wage service occupations is not a key driver of wage trends.
