Adam Smith in “The Wealth of Nations” provided an answer much earlier in a related context: “Commerce and manufactures can seldom flourish long in any state which does not enjoy a regular administration of justice, in which the people do not feel themselves secure in the possession of their property.” More generally, human progress is a function of ideas, individuals and institutions.
Human capital is more difficult to expropriate. The primary reason most individuals invest in human capital (education, trade apprenticeship, professional training) is it enhances their ability to generate income and create wealth. As property crime and violent crime in a city deteriorate, people living in such cities are motivated to leave and move to safer areas. People with higher education and professional training, aka knowledge workers, are more likely to have the economic resources and job opportunities to move to a safer city. In a mirror image of this phenomenon, companies that employ knowledge workers as human capital would be motivated to move from cities with deteriorating crime to safer cities. As these knowledge workers and companies depart cities with growing crime rates, this has a negative multiplier effect on job creation and economic growth.
Technological innovation, primarily driven by the intellectual and creative efforts of knowledge workers, is a key driver of economic growth. Hence, knowledge workers and companies departing cities due to crime compound the negative multiplier effect.
Figure 1 highlights that cities with higher current property crime rates experience lower job growth rates in the future. Besides the size of the economic pie, which is related to the job growth rate, senior policymakers and media across the country are increasingly concerned about how this pie is sliced in terms of poverty and income inequality.
Figure 2 highlights that cities that have a higher current property crime rates experience higher poverty rates in the future. Conceptually, as law and order improves in a city, its citizens and businesses have greater confidence that they can enjoy the benefits of their investment in physical and human capital; that increased incentive to invest in physical and human capital leads to more jobs and income for the broader citizenry, resulting in less poverty.
In a more formal analysis, we found that the above results are statistically significant. Also, we found that cities that had higher current violent crime rates experienced lower job growth rates in the future, and cities that had higher current violent crime rates experienced higher poverty rates in the future. Once again, these relationships are statistically significant.
None of the above results are particularly surprising. In an earlier study, we did a comprehensive analysis of the empirical relationship between economic growth and the rule of law using panel regressions for 134 countries from the period 1984-2019. We documented a significant positive relationship between rule of law and GDP per capita. Also, we documented that countries with greater adherence to rule of law are characterized by less income inequality.
The above analysis leads to the following policy recommendation for political leaders in various cities and states around the country: Focus on ensuring respect for private property rights, effective police forces, prosecutors willing to enforce the rule of law, and fair courts. This will enhance the economic prosperity of your citizens and diminish poverty in your region.
