Steve Williamson has an interesting novel post on corporate taxes in addition to investment, inwards which he claims that taxing corporate profits has no resultant on investment.
The answer is inwards a previous post on the burden of taxation, and Greg Mankiw's algebra but at the terms of repeating let's isolate the key issue. (The previous posts were likewise long, for sure.)
If y'all desire equations, larn dorsum to Greg Mankiw's algebra. There y'all run across a model inwards which corporate taxes practice distort the intertemporal incentive to invest.
The key difference: In his unproblematic model, Greg defines profits equally sales - wages. Then if the work solid pays $100 to invest today, makes $10 out of it tomorrow subsequently paying wages, but faces a 50% revenue enhancement rate, it gets a 5% charge per unit of measurement of return, patch without a corporate revenue enhancement it gets a 10% charge per unit of measurement of return.
Steve defines profits equally sales - payoff - costs of investment. He effectively assumes that all investment is revenue enhancement deductible. Then indeed a constant revenue enhancement charge per unit of measurement does non distort the charge per unit of measurement of return. The work solid gets the revenue enhancement deduction on the investment made today, in addition to that compensates for the lost profits tomorrow.
This is so the same declaration that was floating unopen to finally time, (see posts for links) that total expensing of investment solitary should solve the intertemporal distortions, in addition to so revenue enhancement majuscule at whatever charge per unit of measurement y'all similar including 99.999%.
What's the work amongst that? Well, if y'all apply it completely, at that spot is zero left to tax. If a debt-financed work solid tin deduct from its sales all wages, inputs, investments, in addition to involvement payments, at that spot is zero left to tax.
The revenue enhancement code seems to mean value payments to shareholders are "profits" which tin endure taxed without distortion in addition to involvement payments are "costs" similar the electrical nib that must endure deducted. But at that spot is no fundamental economical distinction betwixt debt in addition to equity equally a marginal root of investment funds. Dividends (and majuscule gains) are the returns y'all must pay to attract equity investors, simply equally involvement is the provide y'all must pay to attract bond investors.
So how practice y'all deduct investment in addition to locomote out something left over to tax? It rests on 2 ideas. First, that the revenue enhancement code tin distinguish "real" investments similar buying forklifts from "financial" investments similar buying stocks in addition to bonds, in addition to alone deduct the former.
Second, that at that spot is some pure "profit," some pure "rent," some "unreproducible input" (i.e. something that did non come upward from a yesteryear unmeasured investment), something similar the classic "unimproved land" that tin endure taxed, without distorting whatever decision. It goes manus inwards manus amongst the complaints of greater monopoly.
But I uncovering it difficult to uncovering in addition to refer a concrete root of profits that, i time named, does non distort the determination to undertake some useful activeness to build those profits. Starting, organizing, in addition to improving a business, figuring out the intangible organizational majuscule that makes it a successful competitor, creating a production in addition to a build name, are all crucial activities for which no investment revenue enhancement credit volition successfully offset a large profits tax. "Intangible capital" is close all most companies get got these days.
Aside the investment distortion, I run across an of import political economic scheme declaration against corporate taxes. Corporations get got a lot of money, in addition to actually expert lawyers in addition to lobbyists. The higher the corporate revenue enhancement rate, the to a greater extent than they volition run to Washington to need exceptional credits, exemptions, in addition to deductions. Like expanded investment deductions. Already, the corporate revenue enhancement was effectively close 20% rather than the statutory 35%. I can't run across whatever defence other than a lower rate, in addition to revenue enhancement people rather than corporations.
Two final points of clarification.
First, Steve positioned his post equally a response to my buyback fallacy post
Second, he writes
Steve didn't enjoin otherwise, but y'all mightiness get got gotten the impression.
What happens if the corporate revenue enhancement charge per unit of measurement goes upward permanently, amongst the revenue enhancement charge per unit of measurement constant forever...? This has no resultant on investment or on the firm's hiring decisions inwards whatever period. That is, if VB is earlier revenue enhancement profits, so (1-t)VB = V, so maximizing VB is the same equally maximizing V, in addition to the revenue enhancement charge per unit of measurement is irrelevant, non alone for investment decisions, but for the firm's hiring decision. In the aggregate, at that spot is no resultant on project demand, in addition to so no resultant on wages.
Basically, investment is an intertemporal determination for the firm. But the corporate revenue enhancement charge per unit of measurement affects per-period after-tax profits inwards just the same agency inwards every period, so at that spot is no resultant on the subsequently revenue enhancement charge per unit of measurement of provide on investment the work solid is facing. Therefore, the work solid won't invest to a greater extent than amongst a lower corporate revenue enhancement charge per unit of measurement ...Steve concludes
But, the revenue enhancement nib is non close investment. The primary resultant is redistribution. In the curt run, the revenue enhancement nib makes the rich richer in addition to the piteous poorer...You tin run across at that spot is a problem. If Steve is right, so why non a 99.999% majuscule revenue enhancement rate? Per Steve, it won't distort whatever decisions, neither investment nor hiring nor starting companies, it volition reach a revenue bonanza for the authorities in addition to it volition transfer income efficiently. Surely if 99.999% corporate taxes had no disincentive effects, governments would get got noticed? Surely non every unmarried Republican is, equally Steve implicitly charges, either lying through his teeth or an economical ignoramus when they solid reason the destination of the revenue enhancement cutting is to spur investment, in addition to thereby productivity in addition to wages?

First, Steve positioned his post equally a response to my buyback fallacy post
"Here's John Cochrane, writing close the 'buyback fallacy:'
'Many commenters on the revenue enhancement nib repeat the worry that companies volition simply operate revenue enhancement savings to pay dividends or purchase dorsum shares rather than build novel investments.'
But, John concludes:
'Investment volition increment if the marginal, after-tax, provide to investment increase...'"The minute point, which nosotros are discussing here, has absolutely zero to practice amongst the get-go point, the buyback fallacy. Whether corporate taxes practice or practice non distort investment decisions, buying dorsum shares has zero to practice amongst it. The buyback fallacy remains a fallacy fifty-fifty if Steve is correct in addition to 99.99% corporate taxes get got no resultant on investment.
Second, he writes
this has no resultant on investment or on the firm's hiring decisions inwards whatever period.Noone, non fifty-fifty Congressional Republicans, claimed that lowering majuscule taxes increases the incentive to hire directly. The argue is clear from the inwards a higher house -- inwards everyone's model, wage payments are deductible, profits = (sales - payoff - ....), payoff larn within the parentheses. The declaration has ever been that lowering corporate profits taxes increases the incentive to invest, in addition to moreover to start novel firms or reorganize them, that this investment would heighten productivity, in addition to that would Pb to higher wages.
Steve didn't enjoin otherwise, but y'all mightiness get got gotten the impression.
