This newspaper’s comprehensive foreign media reports According to the official website of Bocconi University in Italy on August 2，Jerome Ada (Jér, professor of the Department of Economics of the school?A new study "Sources of Wage Growth" by 蝝me Adda and Christian Dustmann, a professor at the Department of Economics at University College London, shows，In the long run，Cognitive-abstract bet365 mobile betting are more conducive to promoting the growth of workers' wages than conventional-manual bet365 mobile betting。

bet365 mobile betting will face many choices in their professional life，What type of work do you do？Participate in training before or after work？Stay working in the same organization or change jobs？Every choice will have an important impact on bet365 mobile betting’ income，But it may not be obvious in the short term。To understand the determinants of wage growth，Ada and Dattersmann designed a mathematical model，And use it to analyze longitudinal data on German male bet365 mobile betting over the past 30 years。Research on labor markets typically divides the tasks performed by bet365 mobile betting into two categories: routine—manual tasks and cognitive—abstract tasks。The former follows clear and repetitive procedures，The training time required is not long；The latter has higher requirements for technical ability and creativity，Requires longer training。

Research results show，The accumulation of conventional-manual bet365 mobile betting and cognitive-abstract bet365 mobile betting are the biggest drivers of wage growth，But they work in different ways。Early in career，Conventional-manual bet365 mobile betting significantly increase workers’ productivity and income，But after the basic bet365 mobile betting are mastered，Their contribution to wage growth will weaken or even disappear。The impact of cognitive-abstract bet365 mobile betting on income takes longer to emerge，But lasts longer，Throughout the worker’s entire career。Therefore，On average，Workers engaged in cognitive-abstract work earn higher wages than those engaged in routine-manual work。

Researchers also examined the impact of cognitive-abstract bet365 mobile betting training on wages。Compared to untrained workers，Workers who are trained in cognitive-abstract bet365 mobile betting before entering the labor market not only earn higher wages，And the unemployment rate is lower，The probability of getting job opportunities in competitive recruitment is also higher。Due to higher stability in the labor market，They can accumulate more experience，And get more rewards。Even excluding differences in workers’ talent levels，Cognitive-abstract bet365 mobile betting bring greater returns to individuals and society。Researchers think，When comparing the different effects of training on workers，It is important to take the entire career as a cycle，Because focusing only on short-term returns may result in the true benefits being underestimated。

Ada and Dattersmann also noticed，Early in career，Changing jobs can significantly increase bet365 mobile betting’ income。But，Liquidity cannot continue to increase salary income，When the salary reaches a certain amount，Changing jobs will not bring about a significant increase in wages。Also，Some bet365 mobile betting take jobs that are not very suitable for them when they first enter the workplace，But the accumulation of relevant experience makes them reluctant to change jobs in the future。

Two scholars said，The above findings have important practical significance。Workers should realize，Cognition-the accumulation of abstract bet365 mobile betting and the benefits of labor training may not be reflected in a short period of time，But it will have a huge positive effect on future careers。Policy makers should realize，The accumulation of work experience may "lock" workers in positions that are not suitable for them，Preventing efficient use of human capital，Job seekers who enter the labor market during a period of limited options (such as a recession) are particularly vulnerable to this situation。
