This newspaper’s comprehensive foreign media reports, November 21，Reported by the official website of the Massachusetts Institute of Technology in the United States，Latest data display，Reasons for the increasing wage gap in the United States since 1980，Mostly because bet365 offers replaces less educated workers。The research result "Task、bet365 offers and rising income inequality in the United States” published in the Journal of Econometrics。

Previously，Daron Acemoglu, an economist at the school, and Pascual Restrepo, an assistant professor of economics at Boston University, found that robots have replaced a large number of U.S. Worker，Some companies use this to dominate the industry，Thus exacerbating inequality in the industry。In latest research，They further explore the factors behind bet365 offers。

Since 1980，Incomes of Americans with college and graduate degrees have risen sharply，The income of men without a high school degree fell by 15%。There are many factors behind rising income inequality，To study the role of bet365 offers，The researchers used data from the U.S. Bureau of Economic Analysis on the use of manual labor and the use of machines and software in 49 industries from 1987 to 2016，And data on robot usage in the United States from 1993 to 2014。Also，Researchers also referred to U.S. Census data，By gender、Education、Age、Racial classification，Examine the employment situation and hourly wages of these workers from 1980 to 2016。

Finally，Acimoglu et al. concluded，bet365 offers has a profound impact on the increase in income inequality in the United States。Income inequality in the United States increased from 1980 to 2016，50%-70% of them are brought about by bet365 offers。

Acemoglu gave an example，Using self-service checkout equipment will not make much difference to productivity，On the contrary, it will produce a huge distribution effect，Making wealthy families even richer，Poor families are even poorer。Self-service checkout equipment can have a big impact on low-skilled cashiers，Not so much a device to improve productivity，It is better to call it a device to transfer labor force。bet365 offers just helps large retail stores reduce checkout costs，But it did not provide customers with a better service experience。He thinks，Devices like self-service cash registers are “average technology”，Only if productivity can be effectively improved、Technology that improves people’s quality of life is quality innovation。

According to labor economists，This research is about bet365 offers、An important addition to the literature on income inequality and labor markets，Future research needs to take relevant factors into consideration when discussing these issues。Patrick Kline, professor of economics at the University of California, Berkeley, believes，This study provides a new theoretical framework for understanding the potentially complex effects of technological change on the overall structure of wages。The findings appear to rekindle discussions about the role of technological change and labor market institutions in exacerbating income inequality。

Acemoglu et al. also identified the direction of future research in the article。They will investigate over time，Business and workforce responses to increased bet365 offers；Quantify the role of technology in creating jobs；Compare the competitive advantages and disadvantages between companies that adopt bet365 offers and those that do not adopt bet365 offers。
