Technology Changes And The Emergence Of New Technologies Strongly Affect: Economics Research Paper, UOL, UK

University University of Leicester (UoL)
Subject Economics


Technology changes and the emergence of new technologies strongly affect the labor market and its components(Bruckner, LaFleur, et al. 2017). Researchers and theorists(Wicksell 1961, Pigou 1962, Marx 1969, Appelbaum and Schettkat 1995, Vivarelli and Pianta 2000, Bogliacino and Pianta 2010) of different schools of economics have tried to identify the amount of these changes and how they affect the labor market in the framework of theoretical and experimental work. From a theoretical point of view, any improvement in technology and technological innovation, on the one hand, destroys existing employment and, on the other hand, creates new job opportunities through product innovation. But this scientific controversy continues because there is no unique model or variable to evaluate the impact of technological change in the literature. However, each of these studies sheds some light on the subject.

Today, new technologies are widely affected by the fear of technological unemployment (Brynjolfsson and McAfee 2011). Regarding the relationship between technology and employment, two fundamental theories contradict each other, with the former stating that technological innovations the same amount of production save labor and create technological unemployment,(Petit 1995, Vivarelli 1995, Vivarelli and Pianta 2000, Coad and Rao 2011, Vivarelli 2014, Dosi and Mohnen 2019, Sasaki 2020, Zhu, Qiu, et al. 2021)and the other claims that it can offset the direct destructive effects of process innovation on employment or even more so by indirect economic effects through product innovation.

Therefore, economic theory does not have a clear answer about the impact of technological change on employment, which depends on several factors; the first of which is the complexity of the indicator of technological change and innovation. Measuring technology change is a very complex subject. Because technology has a wide and deep concept and every day with the spread of science and knowledge, new technologies are either invented or used in the process of production, distribution, and exchange. Some of these technologies affect the way they are produced and distributed, and some of them introduce new products and services to the market.

If at one time technologies such as steam engines, electric conveyors or information technology caused great economic changes and the so-called industrial revolution, today extensive technologies such as artificial intelligence, robotics, virtual reality, cloud system, simulation, Internet, and other technologies in the form of The Fourth Industrial Revolution (or Industry 4.0), they affect economic markets. The labor market and its components such as employment, unemployment, new jobs, wages, and the quality of human labor are undoubtedly affected by these changes. Accordingly, identifying and measuring these changes is a vital issue in economic research.

Previous Empirical Evidence

In recent years, due to the importance of the subject, many studies have been conducted to measure the impact of technological changes on employment at different economic levels (micro and macro)[see; Hall and Heffernan (1985), Layard and Nickell (1985), Van Reenen (1997), Greenan and Guellec (2000), Antonucci and Pianta (2002), Piva and Vivarelli (2005), Lachenmaier and Rottmann (2007), Benavente and Lauterbach (2008), Zimmermann (2009), Bogliacino and Pianta (2010), Meriküll (2010), Coad and Rao (2011), Evangelista and Vezzani (2012), Vivarelli (2014), Van Roy, Vertesy et al. (2015), Ciriaci, Moncada-Paternò-Castello et al. (2016), Ugur and Mitra (2017), Ugur, Awaworyi Churchill et al. (2018), Dosi, Piva et al. (2019)] But all researchers have used almost identical tools and proxies to measure the amount of technology in their research.

For example, Greenan and Guellec (2000)using the variables of process innovation and product innovation, the positive effects of technology on employment were achieved. Then Antonucci and Pianta (2002)used the variables of sales innovation cost and the share of new or improved product in sales to measure technology in their research. Also, Piva and Vivarelli (2005)in 2005 using the cost of research and development failed to achieve a clear result of the impact of technology on employment then Mastrostefano and Pianta (2009) used the level of innovation of companies in products or production process and the share of new or improved product in sales to measure technology, which achieved the positive role of product innovation on employment of high-tech industries.

A year later Bogliacino and Pianta (2010)used the variables of research and development, new product, and new product line in their research and observed the positive effects of technology on employment. Coad and Rao (2011)also cited patents and paid expenditure research and development as indicators for measuring technological change. In 2016 Ugur, Awaworyi et al. (2016)used the variables of research and development intensity, number of patents, number of trademarks, and expansion of knowledge and information and communication technology.

Dosi, Piva et al. (2019)used two variables of technology improvement by adding or moving capital and improving technology without capital and new equipment to measure the impact of technology on employment. Not all variables used can show the positive and negative effects of all variables at all economic levels. The reason that inconsistent and ambiguous results have been obtained from previous studies to measure the impact of technological change on employment is the use of different single variables to show technological change. It seems that building a technology composite indicator to show the impact of technology in different conditions and environments on other variables such as employment, economy, etc. is a basic need.
