We should all agree that we want a more prosperous Minnesota. Here are two specific reforms that will strengthen Minnesota’s economy
— End the state income tax exemption for interest on Minnesota municipal bonds.
— Use the revenue from closing this wasteful tax loophole to cut our high state corporate income tax rate.
Understanding how these reforms will make Minnesota more prosperous is just as important as the ideas themselves. The path to a more prosperous future begins with understanding the process of wealth creation.
Wealth is created when lower-value resources are combined to create a product or service that is worth more than its cost of production.
In the private sector, workers, investors, inventors and businesses combine their resources, knowledge, and effort to supply consumers with a cornucopia of products and services. Competition forces businesses to create value for society. If a business cannot sell its product at a price that covers its costs, it will not survive in the marketplace.
The free enterprise system is dynamic and decentralized. It spontaneously produces and rewards innovations that improve product quality or reduce costs. New inventions and production methods replace dated ideas and organizational structures in the private sector. This constant innovation, spurred by competition, is a major source of economic growth.
The public sector can also create wealth when it takes resources and combines them to produce more value than the cost of the public expenditure. For example, local governments combine a system of sirens with information about severe weather threats from the federal National Weather Service to provide life-saving warnings.
Unfortunately, the public sector is not nearly as nimble and dynamic as the private sector. Government policies that destroy wealth for Minnesotans can persist for decades.
Both the Minnesota municipal bond interest exemption and the state corporate income tax waste valuable resources for Minnesotans. These policies make us poorer by providing tax incentives to divert precious investment dollars away from more socially productive projects.
The Minnesota municipal bond income tax exemption creates a balkanized market for Minnesota state and local bonds because the tax exemption applies to only some of the potential investors in Minnesota municipal bonds. This loophole provides an incentive for investors to divert capital away from the private sector. It also encourages local governments to issue debt inefficiently just to capture some of the implicit state subsidy from the municipal bond exemption.
Economists Mary Lovely and Michael Wasylenko find that Minnesota gives up approximately $1 in lost state income tax revenue from this loophole for each 50 cents in reduced government borrowing costs.
There are good legal reasons to phase out the municipal bond exemption when new bonds are issued to honor the commitments Minnesota made when issuing existing debt. The revenue raised from phasing out this loophole can fund a reduction in the Minnesota corporate income tax rate.
A corporate income tax acts to throw sand into the gears of private sector. As the non-partisan Congressional Budget Office notes, “The domestic distortions that the corporate income tax induces are large compared with the revenues that the tax generates … The corporate income tax has the potential to distort economic incentives and generate inefficiency in at least six ways.”
My cautious review of the academic literature reveals that each dollar of state corporate income tax revenue reduces payrolls by approximately $2. There is not a consensus on the exact size of the reduction in wages and payrolls caused by a marginal dollar of corporate income tax revenue. There are some papers in the literature with estimates of greater harm to workers from high state corporate income taxes. Recent research by economists Alison Felix and James Hines estimates that high state corporate income taxes reduce union wages more than non-union wages.
Combined, these two policies cost Minnesota workers approximately $4 of reduced payrolls for every $1 of benefit provided to Minnesota local governments. Ending this waste should appeal to citizens across the political spectrum.
Admittedly, these two inefficient policies are just the tip of the iceberg. Numerous tax loopholes and government programs need reform. State government should eliminate policies that make Minnesotans poorer, policies that first take resources from where they would be more useful and then squander them.
