This postal service continues the question, who bears the burden of the corporate tax? The side past times side postal service volition receive got broader thoughts on the revenue enhancement conception too economists' reaction to it.
I'm responding inward many ways to Larry Summers, who weighed inward on the corporate taxes number inward a final postal service with a job solid problem
\[\max (1-\tau) \left[ F(K,L) - wL \right] - rK \]
Notice past times the vogue how a corporate revenue enhancement is unlike from a sales tax. Influenza A virus subtype H5N1 sales revenue enhancement only applies to output, therefore the job solid job is
\[\max (1-\tau) F(K,L) - wL - rK \]
The sales revenue enhancement distorts the conclusion to hire labor. The corporate revenue enhancement does non distort that conclusion -- nosotros have \(F_L=w\) because the revenue enhancement applies to both of them.
But what if dividend payments were revenue enhancement deductible? Then we'd have
I'm responding inward many ways to Larry Summers, who weighed inward on the corporate taxes number inward a final postal service with a job solid problem
\[\max (1-\tau) \left[ F(K,L) - wL \right] - rK \]

The sales revenue enhancement distorts the conclusion to hire labor. The corporate revenue enhancement does non distort that conclusion -- nosotros have \(F_L=w\) because the revenue enhancement applies to both of them.
But what if dividend payments were revenue enhancement deductible? Then we'd have
\[\max (1-\tau) \left[ F(K,L) - wL - rK \right] \]
too the conclusion to invest would non live distorted past times the corporate tax. Perhaps to a greater extent than clearly, suppose investment is financed past times retained income, too investment expenditures are completely deductible. Then the firm's job is
\[\max (1-\tau) \left[ F(K,L) - wL - K_{t+1}-(1-\delta)K_t \right] \] where \(\delta\) is depreciation. Again if it's within the brackets, the corporate revenue enhancement does non distort the decision.
If you've taken an economic science course, you lot apace spy the problem. If the corporate revenue enhancement lets firms deduct payments to workers, too therefore lets firms deduct payments to capital, at that spot isn't anything left! \(F(K,L)=F_K K + F_L L = rK + wL\). If economical profits are zero, too nosotros revenue enhancement economical profits, nosotros don't distort whatsoever decisions, but nosotros don't enhance whatsoever coin either.
So suppose at nowadays at that spot is a monopoly element, therefore \(F(K,L) > wL + rK\), revenue exceeds payments to labor too the payments necessary to larn physical capital. Now at that spot is, apparently, a profit, a pure rent, that tin live taxed without distortion!
That is apparently the golden goose of world finance: some origin of pure rent, some completely inelastically supplied factor, that tin live taxed too does non distort whatsoever decision.
Then, too this is the crucial point, Larry (and Paul too company) are asserting that taxing corporate profits does non discourage investment inward whatever is producing corporate profits, therefore it is non-distorting.
Well, is that true?
Here is where I larn a footling frustrated at the eastward coast approach to economical policy making. OK, at that spot is a novel thought floating roughly the correct cocktail parties: "monopoly rents" are on the rise. So nosotros must apace "do something," or inward this instance offering a novel argue for the same former answer, corporate taxes.
Really? If at that spot is pervasive monopoly inward the economy, why isn't the correct world policy reply to arrive at something nearly the monopoly? More to the betoken here, earlier nosotros start taxing things, it is vital to empathise what the origin of the "monopoly" net turn a profit actually is, too live actually certain that taxing it volition non discourage its production, just similar that of physical capital. There is something to the story. Measures of entry too dynamism are indeed vogue down. Corporate profits too stock prices are high, but investment is non next them. High profits should Pb to a wish to expand. But if you lot don't empathise it, you lot tin come upwards apace to incorrect answers.
There are 2 natural stories for monopoly: 1) Government license. Just nearly every long-lasting monopoly inward history is therefore because of regime restrictions on entry too competition. Think taxicabs earlier Uber. We just had a huge increment inward rule of nearly 40% of the economic scheme inward Obamacare too Dodd-Frank, posing explicit too implicit barriers to entry. Regulation too compliance costs receive got increased dramatically inward many other parts of the economic scheme every bit well. But if this is the case, government-created monopoly too and therefore regime taxation of its rents hardly seems similar the ideal policy mix.
2) Intellectual property. Larry mentions this one. Google is, the even out goes, a "monopoly" because it has intellectual belongings others can't match. Drug companies are "monopolies" because they receive got patents that allow them to accuse high prices for drugs. Here I retrieve Larry's (and, to a greater extent than vocally, Paul's) declaration falls apart. Intellectual belongings is not an exogenous fixed factor, the "land" of the reason tax. Intellectual belongings is produced. If Google or the drug companies receive got rents to intellectual property, this is exactly the high charge per unit of measurement of render that provides incentive for people to arrive at novel intellectual property. And taxing it away kills that incentive. Go correct dorsum to Greg's math, too relabel "K" every bit intellectual property.
In sum, for the monopoly declaration to become through, the monopoly rent must accrue to some actually fixed factor, or to some economically wasteful investment such every bit lobbying. If the monopoly rent accrues to intellectual property, or anything else that must live produced, too therefore we're correct dorsum where nosotros started too corporate taxes harm economical growth, investment, too wages.
The declaration is to a greater extent than pervasive. Corporate every bit good every bit personal income taxes send upon people's conclusion to pick out careers, to start a companionship rather than accept a steady project as, say, an economic science teacher. The subsequent profits may await similar "rents," but they are returns to human working capital missive of the alphabet investments, which volition become away if taxed to highly.
Suppose at that spot is, however, some permanent monopoly power, too it accrues to some fixed factor that electrical flow companies have, too volition receive got forever. Never hear how Google unseated the "monopoly" of AOL, Yahoo, too Netscape. Even so, how monopoly ability changes optimal taxes is non (to me, at least) obvious.
The query is non nearly private firm's monopoly power. The query is monopoly ability inward the whole corporate sector. This is the reverse side of the commons fallacy of composition inward taxation. Usually, a job solid may scream, "we can't pay taxes, since if nosotros enhance our prices we'll lose all our business." The job solid ignores the fact that everyone else has to pay the revenue enhancement too, therefore everyone else has to enhance their prices. The firm demand bend is irrelevant; the industry need bend is irrelevant; what matters is the need bend of the whole corporate sector. Individual monopoly ability is non at all manifestly relevant to that question.
My commencement instinct was inward fact the opposite. He or she bears the revenue enhancement who cannot larn out of the way. Hence, if firms receive got monopoly ability over prices too wages, they receive got to a greater extent than ability to enhance prices too reward to pay taxes. This turns out non to live right, or at to the lowest degree upwards to the entry too move out margin which I haven't examined. (If you lot brand companies pay therefore much taxes that they become out of business, you lot larn fewer companies.)
The argue is that inward the presence of monopoly power, firms receive got already raised prices too lowered wages, too adding a corporate revenue enhancement does not alter their incentive. Here is where much of Krugman's writing on monopoly goes wrong, inward my opinion. The fact that at that spot is to a greater extent than coin at that spot does non hateful that when you lot enhance taxes you lot larn the money. Tax theory has to live nearly which decisions are changed past times the tax. You tin sense inward the "monopoly" writing almost a feeling that "tax the corporations" mightiness brand sense, inward work to address righteous indignation at monopoly. But it silent just ain't so.
Perhaps weblog readers are aware of a handling of corporate taxes inward the presence of monopoly too monopsony ability of similar clarity to Greg Mankiw's instance covered inward the last post. It mightiness start amongst Dixit-Stieglitz monopolistically competitive producers, also hiring inward differentiated labor markets giving some monopsony power, too larn all the full general equilibrium parts right.
The inefficiency of the corporate revenue enhancement every bit redistribution
So, inward the final chain of "suppose I'm incorrect nearly all that," let's suppose Larry is correct -- corporate taxes arrive at come upwards out out of stockholders' pockets, too wage growth next a corporate revenue enhancement cutting would live small.
Look at the argument. It is exclusively income-based redistribution. Larry, the preeminent world finance economist of his generation, does non brand arguments nearly economical efficiency, revenue enhancement efficiency, growth of the pie overall, the insane crony-capitalist rot past times which the effective corporate revenue enhancement charge per unit of measurement is one-half its stated rate, or whatsoever of the other things economists usually retrieve nearly when evaluating a tax. His bottom draw is that a corporate revenue enhancement cutting volition enhance wages, but non enough, too it volition enhance stock prices, but also much, too the increment inward the size of the pie is non worth letting the stockholders larn to a greater extent than than he wants them to.
OK, but fifty-fifty so, the corporate revenue enhancement is an insanely inefficient vogue to redistribute income.
Yes, right away stockholders are to a greater extent than wealthy than the average person. But arrive at non forget that most stock is at nowadays held past times institutions -- pension funds, including those of nation too local regime employees that are nearly to sink Illinois too California, nonprofit endowments, 401(k) plans, too therefore on.
Another interesting fact nearly rich people is that they don't pass stock marketplace gains. (I'm pretty certain Larry would endorse this fact, for example, when disliking stimulus efforts that operate through higher stock prices.) So consumption inequality does non rise. "Paper" wealth rises, until the side past times side stock marketplace crash. Is this actually therefore terrible?
Moreover, why must every unmarried chemical factor of the revenue enhancement code live evaluated on its ain for its impact on redistribution across income categories? Why must every unmarried alter inward the revenue enhancement code ever increment income-based redistribution, too live evaluated only on that basis?
Why is it out of consideration to eliminate the highly distorting corporate revenue enhancement too brand upwards the redistribution amongst a to a greater extent than progressive personal income tax, or amongst elimination of the nation too local deduction, mortgage involvement deduction, wellness attention deduction, too charitable deduction, which only arrive at goodness people inward the highest revenue enhancement brackets. (Those deductions actually are "tax cuts for the rich!")?
And does the regime non pass money? And is non the vast bulk of that coin spent on redistribution (social security, medicare, medicaid, pensions, etc.?)
Economists receive got a few basic insights to contribute to world policy. 1) Don't revenue enhancement vino to a greater extent than than beer inward an endeavor to redistribute income. Do redistribution efficiently through a progressive income or meliorate consumption tax. 2) Evaluate things similar redistribution comprehensively, non on a instance past times instance basis. You tin arrive at a lot meliorate if you lot are allowed to merchandise off a footling less redistribution inward a grossly inefficient revenue enhancement for a footling to a greater extent than redistribution inward a less inefficient revenue enhancement or inward a spending program.
Yes, Democratic politicians receive got decided that their best talking betoken is to echo "tax cuts for the rich" no affair what the Administration too congressional republicans propose, too to assail elements they don't similar (corporate revenue enhancement cuts) on that basis, piece conveniently ignoring regressive elements they arrive at like, such every bit the deductions for nation too local taxes. But does merely echoing that political talking betoken amongst equations actually assist us all to the finish of a meliorate economy?
(To live fair, Larry also complained that the reduction inward rates does non come upwards amongst plenty base of operations broadening, therefore it increases the deficit -- -meaning futurity taxes, or unspecified spending cuts. This is a valid argument, which I volition accept upwards inward the side past times side post.)
The CEA has just issued a white paper, "The growth effects of revenue enhancement reform too implications for wages" I can't hold off to hear the analysis. Let me guess.. "tax cuts for the rich?" No, sure that would live also predictable.
Update:
Pietro Peretto reminds me at that spot is an active literature on optimal taxation inward endogenous-growth economies, including his Corporate taxes, growth too welfare inward a Schumpeterian economy , Schumpeterian Growth amongst Productive Public Spending too Distortionary Taxation, The Growth too Welfare Effects of Deficit-Financed Dividend Tax Cuts and Implications of Tax Policy for Innovation too Aggregate Productivity Growth. Nir Javinovich too Sergio Rebelo receive got a overnice recent "Nonlinear effects of taxation on growth,'' inward the JPE, Nancy Stokey too Sergio receive got "Growth effects of flat-rate taxes" also inward the JPE, too I receive got within data that Republic of Chad Jones is working on it too. So, at that spot is no lack of academic literature on the query just which kinds of taxes trim growth, which of course of written report leads to huge distortions. On the other hand, given the utter distaste of people inward this policy news to verbalise nearly incentives too growth rather than redistribution at all, the lessons of this literature volition probable receive got to hold off for the side past times side revenue enhancement reform. Let us promise it's non some other 31 years.
