Marginal tax rate

The belief that what could be true for any unit taken separately could also be lure for ail units taken simultaneously is sometimes called the "fallacy of composition." We commit it when we apply the marginal tax rate to calculate the real cost of all tax deductible items, thus forgetting that only one dollar can be the last dollar. 

These capital cost factors were based on an assumption that each technology faces an 11 percent nominal interest rate, with 2 percent inflation in the economy, a marginal tax rate of 33 percent, a 10-year tax life, and a 20-year project life. 

A high marginal tax rate lowers the opportunity cost or "price" of leisure, and, as with any commodity whose price is reduced, thereby encourages people to consume more of it (and thus do less work). But, on the other hand, it also lowers people s incomes, and thereby may induce them to work harder so... 

The combination of a NMW with tax credits and other reforms has reduced the severity of the unemployment and poverty traps. Table 29 illustrates the impact of the Government s reforms on high effective marginal tax rates (EMTRs) between 1998 and 2007. Table 30 illustrates real terms increase in what the Government describes as the Minimum Income Guarantee between 1999 and 2007. These theoretical incentives are personalised through software packages used by front line advisers that enable them to provide individualised better off in work calculations for unemployed and other workless claimants. 

Like all business expenses, R D is deductible from a fro s taxable income. This tax deduction reduces the cost of R D by the amount of the company marginal tax rate. Because of the size and sales of most major pharmaceutical fins, the bulk of their taxable income would fall into the highest tax bracket. This marginal tax rate fell from 48 to 46 percent between 1971 and 1986. At 46 percent, every dollar spent on R D would cost the company only 0.54. With the passage of the Tax Reform Act of 1986 (Public Law 99-514), the marginal rate fell to 34 percent, thus effectively raising the cost of each dollar of R D to 0.66. Corporations also pay State income taxes which also can be reduced with business deductions. 

To illustrate how important tax savings are to net R D costs, OTA recalculated the R D cost per new chemical entity from DiMasi s estimates (table 3-10). The sample of NCEs that DiMasi studied underwent the great bulk of discovery and development at a time when the marginal tax rate was 46 to 48 percent. Adjusting for tax savings (using a 46-percent rate) without any other changes reduces the net cash outlays per NCE from 127.2 million to 65.5 million, and it reduces the total costs capitalized to the point of market introduction from 259 million to 140 million. When the cost of capital was permitted to decrease linearly from 14 to 10 percent over the... 

The average effective tax rate for the industry after 1987 is likely to decline because the Tax Reform Act of 1986 reduced the U.S. corporate marginal tax rate after 1986. In 1987, the top Federal statutory marginal tax rate was 40 percent, compared with 46 percent in 1986, and it dropped to 34 percent in 1988. Therefore, when the effect of tax credits and deferments is taken into account, the average effective tax rate is likely to be even lower than 32 percent in years after 1987. For the drugs approved in 1981-83, the lower tax rate would have gone into effect in the 4th to 7th year after product launch.24... 

Myers and Shyam-Sunder calculated the cost of debt capital for a sample of 17 pharmaceutical companies. In January 1990, the market value weighted cost of debt for pharmaceuticals was 9.1 percent (285). The January 1990 cost of debt net of taxes, with a marginal tax rate of 34 percent, is therefore 6.0 percent. Before the Tax Reform Act of 1986 lowered marginal tax rates, the marginal tax rate was 46 to 48 percent, which would imply a net after-tax cost of debt of 4.9 percent. 

A 38% marginal tax rate (34% federal, 4% state and local) is included in the return on investment calculation. 

Interest, dividends, and short-term capital gains are taxed at ordinary income rates in the United States. The combined federal, state, and local marginal tax rate on such income approaches 50% in some jurisdictions. In contrast, long-term capital gains are taxed at a maximum of 20%, which can be postponed until realization upon sale. For this reason, equities are tax advantaged compared with bonds and investments that deliver ordinary income. 

Actual Dollar Analysis Assume a single emnual inflation rate of 5% for the revenues, expenses, and salvage value of the asset at the end of period 3. As before, the interest and principal payments are not affected by inflation. Table 5 provides the actued cash flows for this example. Note that depreciation expenses are provided in order to cedculate taxes edthough they ace not cash flows. For the sake of simplicity, we assume a margined tax rate of 40%, which is edso applied to capited geuns. 

The theoretical model predicts that reduction in work efforts will he proportional to the size of the benefit (income effect) and the implicit marginal tax rate on earnings of the program (price effect). The theory thus supports the view that the impact of safety net programs on work disincentives should be smaller in developing countries, for four reasons ... 

Very few programs in developing countries use and are able to enforce effectively benefit formulas with marginal tax rates and frequent recertification of household... 

To differentiate redemption yield from other yield and interest rate measures described in this book, it will be referred to as rm. Note that this section is concerned with the gross redemption yield, the yield that results from payment of coupons without deduction of any withholding tax. The net redemption yield is what will be received if the bond is traded in a market where bonds pay coupon net, without withholding tax. It is obtained by multiplying the coupon rate Cby (1 — marginal tax rate). The net redemption yield is always lower than the gross redemption yield. 

Indirect Labor Costs = 2.5% of the annual product cost Inventory Costs = 15% of the average inventory cost Scrap Costs = 15% of the annual product cost After-Tax Savings = (Savings)(1 - Marginal Tax Rate=40%) ...
