Hello, and welcome to paper-to-podcast. Today's episode is going to leave you with the burning question: "Should we tax the robots?" This is not a plotline from a science fiction novel, but a serious economic interrogation put forward by Joao Guerreiro, Sergio Rebelo, Pedro Teles and colleagues.
In a nutshell, these number-crunching wizards have discovered that the ever-growing use of robots could send income inequality in the United States skyrocketing. They've developed a nifty model that reveals if the cost of automation - that's robots muscling in on human jobs - continues to shrink, the rich will reap the benefits while the poor will be left in the dust.
Now, here's where things get interesting. These same brainiacs suggest that we could stop this unfair wealth distribution in its tracks by slapping a tax on robots. Yes, you heard it right! According to their calculations, the ideal robot tax would be around 5.1% in 2018, dwindling to 2.2% in 2028, and a mere 0.6% in 2038. After that, the taxman can retire his robot-taxing calculator.
But before we start celebrating, there's a catch. This plan could blow up in our faces if we don't provide enough incentives for people to acquire non-routine skills - the ones robots can't master. If we fail to do so, income inequality might still rise. So, it's a two-pronged strategy: tax the bots and educate the humans.
How did they come up with this? Well, they used a blend of mathematical modeling and data analysis, dividing work into two categories: routine and non-routine. Robots are seen as replacements for routine workers and helpful buddies to non-routine workers. Starting with a static model with fixed occupations, they then expanded to a dynamic model where workers choose their occupation when entering the workforce. They then calibrated their models using data from the Current Population Survey, reflecting the U.S. economy from 1987-2017.
Their approach is truly commendable, using a detailed model considering technical progress in automation and the choice of skills. They effectively tie their model to real-world scenarios, providing a comprehensive and relevant picture of the issue.
However, all good studies have their limitations. The study assumes that robots wholly replace routine workers and only assist non-routine workers. In reality, the impact of automation is more nuanced across different roles and industries. The model also simplifies some aspects of the labor market and doesn't account for income risk or the possibility of taxing automation directly. Plus, it's silent on the effect of technological advancements other than automation.
Despite the limitations, the findings have numerous potential applications. Policymakers, corporations, educators, and career advisors could all benefit from this research, guiding tax policies, investment decisions, and career advice. It also opens the door for further academic studies on the economic and social implications of automation.
So, the next time you see a robot, don't be surprised if it's carrying a tax bill. But remember, it's all in the name of keeping income inequality in check and encouraging us humans to learn new skills. In the meantime, keep an eye out for those tax-collecting robots - who knows, they might be coming to a workplace near you!

Supporting Analysis
So, get this. A bunch of brainiacs crunched some numbers and found out that if we keep using robots at the current rate, income inequality in the U.S. could go through the roof. They made this fancy model that showed if the cost of automation (that's robots taking over jobs) keeps dropping, the rich will get richer and the poor will get poorer. Now, here's the kicker. These same eggheads say we could stop this by taxing robots! Yup, you heard it right. They found that the best tax on robots would be around 5.1% in 2018, then drop to 2.2% in 2028, and 0.6% in 2038. After that, we won't need to tax robots at all. But don't think we're out of the woods yet. They also found that this plan could backfire if we don't give people enough incentive to acquire non-routine skills (you know, the kind robots can't do). If we don't, then income inequality could still rise. So, basically, it's tax the bots and teach the humans… or else!
This paper uses a combination of mathematical modeling and data analysis to explore the potential economic implications of taxing robots. The researchers divided work into two categories: routine and non-routine, where robots are seen as substitutes for routine workers and complements to non-routine workers. They initially examined a static model where worker occupations are fixed, then moved on to a dynamic model with endogenous skill acquisition, where workers choose their occupation when they enter the workforce. They used these models to analyze how changes in automation costs would impact income inequality and the optimal tax system. The models also factored in the government's ability to observe worker income and robot purchases but not worker type or labor input. The researchers then calibrated their models to match salient features of the U.S. economy from 1987-2017, using data from the Current Population Survey. The modeling and analysis were used to explore whether it is optimal to tax robots and how changes in automation costs might impact optimal taxation policies.
The researchers' approach to addressing the complex issue of robot taxation is truly compelling. They adeptly utilise a quantitative model that considers technical progress in automation and the endogenous choice of skills. This allows for a detailed exploration of how ongoing decreases in automation costs could potentially exacerbate income inequality, thereby providing a comprehensive picture of the issue at hand. The use of a static model to initially address optimal policy questions and later a dynamic model with endogenous skill acquisition is a commendable methodology. This approach allows the researchers to consider both immediate and long-term implications of varying tax systems and automation costs. The researchers also do an excellent job of grounding their model in real-world context. They calibrate their model to align with features of the U.S. economy, ensuring their findings are relevant and applicable. This adherence to reality bolsters the integrity of their work. Lastly, the paper is laudable for its clear and methodical structure, with each section building upon the last. This makes a complex topic more accessible, a crucial aspect in discussions surrounding economic policy.
The study, while comprehensive, has some limitations. It assumes that robots entirely replace routine workers and perfectly complement non-routine workers. In reality, the effect of automation might be more nuanced with a varying degree of replacement and complementation across different roles and industries. The study also uses a simplified model where each period represents a decade and workers live for six decades, working for the first four and retiring in the last two. This may not accurately represent real-life labor market dynamics. The model doesn't consider the potential for workers to retrain or switch occupations later in life. Additionally, the research does not account for idiosyncratic income risk or the possibility of taxing automation directly. Lastly, the model does not reflect the impacts of technological advancements other than automation, which could also drastically affect labor markets and income distribution.
The research on taxing robots can be applied in various policy-making scenarios, particularly in the context of labor economics and fiscal policy. As automation takes over certain jobs, this research could guide policymakers in developing tax policies that could mitigate income inequality and provide support for displaced workers. Governments could use this study to reconsider their tax systems and potentially introduce new tax categories for automated systems or robots. Additionally, corporations investing heavily in automation might use this paper to anticipate potential changes in taxation and other regulatory measures. Educators and career advisors could also use the research to better understand the evolving job market and guide students towards non-routine occupations that are less likely to be automated. Lastly, this research could stimulate further academic studies on the economic and social implications of automation.
