Revenue-Neutral Tax Reform
  • The goal is to increase the size of the economy
    while meeting the needed revenue goal
  • Reduce reliance on costly inefficient taxes
  • Increase reliance on less distortionary taxes
  • Generally,
  • avoid high tax rates with narrow tax bases that
    are highly responsive to tax rates
  • use low tax rates on broad bases that are less
    responsive to tax rates

The inefficiency of a tax increases with the
square of the tax rate
Marginal distortions associated with the tax
code tend to rise with the square of the tax
rate, so that as the tax rate gets into higher
and higher territory, the marginal dead-weight
losses tend to grow rapidly. Going from a 30
percent to a 40 percent marginal tax rate, for
example, doesnt increase the marginal efficiency
cost of taxation by a factor of 1.33, but by the
ratio of 16 over 9close to 75 percent. Source

A Tax Theorists Guide to Spotting Better and
Worse Taxes for Economic Growth
  • Better Taxes for Growth
  • Minimally reduce gains from trade
  • An inelastic tax base
  • Small tax rate wedge
  • (from combine federal and state rates)
  • Low administrative costs
  • Low compliance burden
  • Worse Taxes for Growth
  • Large distortions in the decisions of people and
    businesses
  • Multiple ways for creative individuals to change
    behavior
  • A large tax rate wedge
  • (from combine federal and state rates)
  • A highly mobile tax base
  • High administrative costs
  • Large compliance burden

Minnesota is a Small Open Economy
  • Minnesota has 0.08 of the world population.
  • Minnesota GDP is about 0.33 of world GDP.
  • We should compare our taxation of
  • capital internationally, as capital is
  • highly mobile today.
  • We should compare our taxation of
  • labor and savings nationally, because high
  • human capital workers are very
  • mobile today.
  • How does Minnesota compare
  • Internationally? What decisions face huge
  • combined Minnesota and federal tax rates?

Minnesota is a Small Open Economy -but Minnesota
has a Tax Code Designed for a Closed Economy
  • Minnesotas 41.4 combined statutory federal and
    state corporate income tax rate is 50 higher
    than the OECD average of 27.6.
  • Original idea - place the burden of the state
    corporate income tax on the owners of capital
    invested in Minnesota
  • Minnesota taxes intended to fall on capital miss
    in an open economy
  • Minnesota workers, consumers, and land owners get
    hit by taxes designed to burden owners of capital
  • How we tax Minnesota source-based capital
    determines how much capital is invested in
    Minnesota
  • - but not the world rate of return on capital.
  • The pre-tax rate of return hurdle for investments
    in Minnesota is higher because competition in the
    capital market equalizes after tax rates of
    return across jurisdictions adjusting for risk.

8
Specifically, how do we learn what are better
and worse taxes for economic growth and
prosperity?
  • Even an ideal tax system would create some extra
    tax burden in excess of tax receipts to meet our
    need revenue target.
  • Analysis should be grounded in the economic
    theory of taxation
  • Rely on the serious, scholarly empirical research
    on the effects of taxes on economic decision
    making and economic performance

Specific problems caused by the Minnesota
Corporate Franchise Tax
  • A high rate (41.4 ) even before considering the
    double taxation of corporate income
  • Strong disincentive for C-corp investment in
    Minnesota
  • -Foreign Direct Investment in a state falls one
    percent for every one percent increase in the
    state corporate income tax rate.
  • Source Prof. Claudio A. Agostini, Public
    Finance Review, 2007
  • - ... the effective corporate tax rate has a
    large adverse impact on aggregate investment,
    FDI, and entrepreneurial activity. For example, a
    10 percent increase in the effective corporate
    tax rate reduces aggregate investment to GDP
    ratio by 2 percentage points. Corporate tax rates
    are also negatively correlated with growth, and
    positively correlated with the size of the
    informal economy.
  • Prof. Andrei Shleifer, et. al, Harvard
    University
  • It doesnt collect much revenue for a tax with a
    9.8 rate.

10
Specific problems caused by the Minnesota
Corporate Franchise Tax
  • The domestic distortions that the corporate
    income tax induces are large compared with the
    revenues that the tax generatesOverall, on the
    basis of a survey of estimates derived from
    published corporate tax studies, Gravelle
    concludes that the combined cost of the first
    five domestic inefficiencies discussed in this
    chapter could exceed the total amount of
    corporate tax revenues collected. CBO, 2005
  • Corporate income taxes appear to have a
    particularly negative impact on GDP per capita.
    This is consistent with the previously reviewed
    evidence and empirical findings that lowering
    corporate taxes raises TFP growth and investment.
    Reducing the corporate tax rate also appears to
    be particularly beneficial for TFP growth of the
    most dynamic and innovative firms. Thus, it seems
    that corporate taxation affects performance
    particularly in industries and firms that are
    likely to add to growth.

Specific problems caused by the Minnesota
Corporate Franchise Tax
  • It distorts firms decisions between equity and
    debt finance
  • It has the highest administrative cost for the
    DOR per dollar raised
  • It is a regressive and probably highly regressive
    tax that falls on in-state consumers and workers.
  • Perhaps shockingly, the current Minnesota CFT,
    or any heavily sales apportioned state income
    tax, acts to place a hidden, and somewhat
    arbitrary form of sales tax on everything sold in
    the state by corporations, including food,
    prescription drugs, clothing, and other goods
    that may be popularly thought to be tax free.
  • in the long-run a 1 increase in the tax bill
    tends to reduce real wages at the median by 92
    cents.

Specific problems caused by the Minnesota
Personal Income Tax on Wages
  • Minnesotas has a 40.1 current combined
    statutory top federal and state personal income
    tax rate.
  • The original idea is to place the burden of the
    state personal income tax on households with high
    personal income in Minnesota as if Minnesota was
    a closed economy.
  • A large disincentive to supply additional hours
    of effort
  • Icelands Natural Experiment
  • A large disincentive to invest in education and
    on-the-job-training
  • A large disincentive to take risky, disagreeable
    jobs that receive a compensating wage premium for
    less pleasant working conditions
  • A strong incentive to take compensation in tax
    preferred forms (perks, exotic business trips,
    benefits, ect.)

15
Specific problems caused by the Minnesota
Personal Income Tax on Wages
  • Labor mobility of highly skilled individuals
  • The evidence presented in this paper supports
    the basic theoretical presumption that state and
    local governments cannot redistribute income.
    Since individuals can avoid unfavorable taxes by
    migrating to jurisdictions that offer more
    favorable tax conditions, a relatively
    unfavorable tax will cause gross wages to adjust
    until the resulting net wage is equal to that
    available elsewhere. The current empirical
    findings go beyond confirming this long-run
    tendency and show that gross wages adjust rapidly
    to the changing tax environment. Thus, states
    cannot redistribute income for a period of even a
    few years. The adjustment of gross wages to tax
    rates implies that a more progressive tax system
    raises the cost to firms of hiring more highly
    skilled employees and reduces the cost of lower
    skilled labor. A more progressive tax thus
    induces firms to hire fewer high skilled
    employees and to hire more low skilled employees.
    Since state taxes cannot alter net wages, there
    can be no trade-off at the state level between
    distribution goals and economic efficiency.
    Shifts in state tax progressivity, by altering
    the structure of employment in the state and
    distorting the mix of labor inputs used by firms
    in the state, create deadweight efficiency losses
    without achieving any net redistribution.

    of Public Economics, 1998.

Specific problems caused by the Minnesota
Personal Income Tax on Wages?
  • Labor mobility of highly skilled individuals
  • This paper examines the responsiveness of the
    rich to state income taxes. We use Major League
    Baseball free agents who were named All-Stars at
    some point in their career and who signed with a
    U.S. team for the 1991 through 2002 seasons. This
    data set overcomes some of the previous
    difficulties encountered in similar studies but
    also has limitations representing the general
    rich population. We find evidence that the wages
    of this subset of players do adjust to offset the
    burden of state income taxes, specifically a 1
    decrease in net-of-tax rate leads to a 3.3
    increase in salary. Professors Ross and Dunn,
    Contemporary Economic Policy, 2008
  • High combined state and federal tax rates leads
    to a high marginal cost of public funds, even
    without considering labor mobility.
  • An across-the board increase in personal tax
    rates involves a deadweight loss of 76 cents per
    dollar of revenue and collects only about
    two-thirds of the revenue implied by a static
    calculation. Feldstein, The Effects of Taxes
    on Efficiency and Growth. Tax Notes, 2006.

17
Specific problems caused by the Minnesota
Personal Income Tax on Saving
  • The effective combined effects of federal and
    state taxes and inflation results in a tax rate
    on saving through banks or bonds can easily
    exceed 100 annually!
  • Taxing capital involves taxing income twice
    once when you receive it, before you save it, and
    then once again when you get the return on the
    savings. It gives a bias toward consuming now
    rather than consuming later and depresses capital
    accumulation.

    Lucas, in the Region Magazine from the
    Minneapolis Federal Reserve Bank

Tax and Economic Growth -OECD Conclusions
The analysis in this (OECD) paper suggests some
general policy options that could be
considered - The reviewed evidence and the
empirical work suggests a tax and growth
ranking with recurrent taxes on immovable
property being the least distortive tax
instrument in terms of reducing long-run GDP per
capita, followed by consumption taxes (and other
property taxes), personal income taxes and
corporate income taxes. - A revenue neutral
growth-oriented tax reform would be to shift part
of the revenue base from income taxes to less
distortive taxes In practical policy terms, a
greater revenue shift could probably be achieved
into consumption taxes.
