Taxation, Corruption, and Growth

Abstract

We build an endogenous growth model to analyze the relationships between taxation, corruption, and economic growth. Entrepreneurs lie at the center of the model and face disincentive effects from taxation but acquire positive benefits from public infrastructure. Political corruption governs the efficiency with which tax revenues are translated into infrastructure. The model predicts an inverted-U relationship between taxation and growth, with corruption reducing the optimal taxation level. We find evidence consistent with these predictions and the entrepreneurial channel using data from the Longitudinal Business Database of the US Census Bureau. The marginal effect of taxation for growth for a state at the 10th or 25th percentile of corruption is significantly positive; on the other hand, the marginal effects of taxation for growth for a state at the 90th percentile of corruption are much lower across the board. We make progress towards causality through Granger-style tests and by considering periphery counties where effective tax policy is largely driven by bordering states. Finally, we calibrate our model and find that the calibrated taxation rate of 37% is fairly close to the model's estimated welfare maximizing taxation rate of 42%. Reducing corruption provides the largest potential impact for welfare gain through its impact on the uses of tax revenues.

Networking and the giving and receiving of advice outside of one’s own firm are important features of entrepreneurship and innovation. We study how immigrants and natives utilize the potential networking opportunities provided by CIC, formerly known as the Cambridge Innovation Center. CIC is widely considered the center of the Boston entrepreneurial ecosystem. We surveyed 1,334 people working at CIC in three locations spread across the Boston area and CIC’s first expansion facility in St. Louis, Missouri. Survey responses show that immigrants value networking capabilities in CIC more than natives, and the networks developed by immigrants at CIC tend to be larger. Immigrants report substantially greater rates of giving and receiving advice than natives for six surveyed factors: business operations, venture financing, technology, suppliers, people to recruit, and customers. The structure and composition of CIC floors has only a modest influence on these immigrant versus native differences.

This primer provides an overview of the implications of automation technology based on state-of-the-art "Artificial Intelligence" (AI) in the late 2010s: including the trends leading to the surge in AI, applications of AI categorized by the type of work performed, limitations of the technology, discussion about AI adoption, and key concerns the technology brought about.
