Prominent Economist Identifies Fundamental Issues in the US Economy

**Ufuk Akcigit’s Research Reveals the Decline of U.S. Economic Dynamism**


Ufuk Akcigit, a distinguished economist and professor of economics at the University of Chicago, has conducted extensive research on quantitative economic growth. His work focuses on understanding how market innovation and policy impact an economy’s expansion. In recent years, Akcigit has delved into the topic of “business dynamism” and its implications for economic growth, particularly in the United States.

**The Decline of Business Dynamism in the U.S.**

Business dynamism, which measures the rate of new firm creation in markets, is closely tied to innovation and productivity. However, Akcigit’s research has revealed that the United States has experienced a significant decline in business dynamism since the 1980s. This decline has raised concerns about the country’s ability to sustain growth and remain a dominant economic force in the long term.

One of the key factors contributing to this decline is the increasing concentration of markets, which has reduced competition and hindered the entry of new businesses. Dominated by established players, these concentrated markets lack the driving force of innovative firms that could push the sectors forward. This lack of turnover in the market has had a negative impact on productivity and creative momentum.

**Knowledge Diffusion: A Crucial Factor in Economic Growth**

Akcigit and his co-author, Sina T. Ates, have identified “poor knowledge diffusion” as a primary cause of fading U.S. dynamism. Knowledge diffusion refers to the spread of innovation across an industry. When a firm makes a breakthrough, the dissemination of its ideas can lead to increased productivity across the sector. However, Akcigit and Ates found that these breakthroughs have become more concentrated among existing market leaders, limiting the benefits to the broader economy.

The decline in knowledge diffusion can be attributed to several factors. First, the outsourcing of production has reduced interaction between firms in the same area, limiting opportunities for learning from one another. Second, the rise of data as a form of capital has made it difficult for smaller rivals to compete with established firms that have access to larger databases and customer bases. Finally, intellectual property concentration, as measured by patent ownership, has increased significantly, with the largest firms monopolizing new ideas and hindering competition.

**The Need for Democratic Distribution of Ideas**

To address the decline in business dynamism and promote sustained economic growth, Akcigit asserts the importance of a democratic distribution of ideas. Knowledge diffusion plays a crucial role in boosting productivity, and ensuring that innovative ideas can benefit the broader society is essential. However, with the current concentration of knowledge and intellectual property, established firms have a disproportionate advantage, hindering the overall productivity and dynamism of the economy.

**Possible Solutions**

Recognizing the need to address the decline in business dynamism, policymakers, including President Joe Biden, have prioritized pro-competitive reforms. These reforms aim to promote greater competition in markets and reduce the concentration of power among established firms. Key policy areas include antitrust regulations to tackle market concentration, intellectual property reforms to prevent the monopolization of ideas, and initiatives to promote knowledge diffusion across industries.


Ufuk Akcigit’s research on business dynamism and its decline in the United States has shed light on the challenges facing the country’s economic growth. The concentration of markets, the decline in knowledge diffusion, and the increasing monopolization of intellectual property have all contributed to the decline in business dynamism. Addressing these issues through pro-competitive reforms and promoting a democratic distribution of ideas will be crucial in revitalizing economic growth and ensuring long-term prosperity.
