Transition to Clean Technology

by Daron Acemoglu, Ufuk Akcigit, Douglas Hanley and William R. Kerr

Abstract

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation, in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean technology can be difficult both because clean research must climb several rungs to catch up with dirty technology and because this gap discourages research effort directed towards clean technologies. Carbon taxes and research subsidies may nonetheless encourage production and innovation in clean technologies, though the transition will typically be slow. We characterize certain general properties of the transition path from dirty to clean technology. We then estimate the model using a combination of regression analysis on the relationship between R&D and patents, and simulated method of moments using microdata on employment, production, R&D, firm growth, entry and exit from the US energy sector. The model's quantitative implications match a range of moments not targeted in the estimation quite well. We then characterize the optimal policy path implied by the model and our estimates. Optimal policy makes heavy use of research subsidies as well as carbon taxes. We use the model to evaluate the welfare consequences of a range of alternative policies.

AT&T, Retraining, and the Workforce of Tomorrow

William R. Kerr, Joseph B. Fuller and Carl Kreitzberg

By the late 2000s, rapid changes in the telecommunications industry forced AT&T’s management team to take on a task that CEO Randall Stephenson called the “biggest logistical challenge” they had ever seen: retraining 100,000 workers by 2020. In 2012, internal company analyses found that AT&T’s workforce would lack the skills it needed to fulfill emerging job requirements. AT&T responded by creating “Workforce 2020,” a company-wide initiative that sought to address potential skill shortfalls. The initiative aimed to transform AT&T’s workforce by implementing multiple changes, such as redesigning job roles, developing new educational curricula with Udacity, and incentivizing employees to retrain themselves for high-demand careers. Some gave high praise to the “Workforce 2020” model, going so far as to call it a new “social contract” between employers and employees. Others worried that the new program was systematically disadvantaging specific groups of workers. In 2018, AT&T rebranded Workforce 2020 to “Future Ready,” signaling the company’s commitment to retraining its workforce beyond 2020.

Talent is a critical resource for today’s knowledge economy. The United States has benefited substantially from high-skilled migration since the 1970s, especially with respect to innovation and entrepreneurship. This chapter reviews data on these immigrant contributions, and it discusses the important roles played by universities and firms under the American system. The chapter concludes with ways that U.S. immigration policy could be enhanced, which will become more important as other nations become more competitive for global talent.

Immigrants account for about a quarter of U.S. invention and entrepreneurship despite a policy environment that is not well suited for these purposes. This chapter reviews the U.S. immigration policy environment that governs how skilled migrants move to America for employment-based purposes. We discuss points of strain in the current system and potential policy reforms that would likely increase the rate of innovation and the number of startups due to immigrants in the country. Key areas include adjustments to the allocation of permanent residency visas, adjustments to the H-1B visa program, and the creation of an immigrant startup visa.
