A Systematic Review of Health Economics Simulation Models of Chronic Obstructive Pulmonary Disease.

Zafari Z, Bryan S, Sin DD, Conte T, Khakban R, Sadatsafavi M.

The most common lifestyle interventions researched in asthma focus on manipulating diet and/or exercise, with specific attention to obesity. Other interventions that have been tested in studies of varying quality include meditation, yoga, massage therapy, and acupuncture.

Decision analysis is a formalized approach to making optimal choices under conditions of uncertainty. It allows the user to enter costs, probabilities, and health-related quality of life values among other inputs of interest, and then calculates probabilistically weighted means of these outcome measures.

Heap Corporation is considering an investment in a project that will have a two year life. The project will provide a 10% intern

Vlad1618 [11]

Answer:

$77,660

Explanation:

IRR signifies the interest rate where the net present value equals zero.

In order to reverse work the investment, the present values of the cash flow from this new project - when discounted at 10% should equal the amount of investment.

IRR signifies that Initial outlay - PV Cash flows @ 10% = 0

We calculate the present values as,

PV = 40,000 * (1 / 1+0.10) + 50,000 * [1 / ((1+0.10)^2)}

PV = $77,685.9 (rounded off)

This is closest to $77,660, which is the initial outlay required to to generate above mentioned pc vash flows and an irr of 10%.

Hope that helps.

The value of a firm is maximized when the: Multiple Choice

dsp73

Answer:

weighted average cost of capital is minimized

Explanation:

Weighted average cost of capital (WACC) in accounting is the average rate of return a company is expected to compensate all its various investors by comparing its debt and equity structure.

The value of a firm is maximized when the weighted average cost of capital is minimized.

The formula to calculate the weighted average cost of capital (WACC) is:

WACC = ((E ÷ V) x Re) + (((D ÷ V) x Rd) x (1 - T))

Where;

Re=Cost of equity

Rd=Cost of debt

E=Market value of equity

D=Market value of debt

T=Effective tax rate

V=Total market value of combined equity and debt

An automobile final assembly plant has an annual production capacity of 200,000 cars. The plant operates 50 weeks/yr, 2 shifts/d

notka56 [123]

Answer:

a) Rp= 200,000 / (50 X 10 X 8)= 50.0 units /hr

b) Tc= E/Rp= 60 (0.95) /50 =1.14 min

Ts= Tc - Tr = 1.14 - 0.15 = 0.99 min

w= Min Int > Twc/EbTs= 15.0 X 60 / (0.93 X 0.99) ) 944.5 rounded: 978 workers /shift

Total number of workers = 1956 over 2 shifts

n= w/M = 978/2.2 = 444.3 rounded 445 stations

Annual workload WL = 200,000 cars x 15/hr/car = 3,000,000 hr/work

with 1956 workers,= 1956 (50 X 10 X 8) = 3,912000 hr

This doesn´t include E, Eb and Er

E= 0.95 (given), Eb= 0.93 and Er= 0.99/1.14= 0.8684

Usable service time: 3, 912,000 (0.95) (0.93( (0.8684) = 3,912,000(0.767) = 3,001, 409 hr

C) the plant operates (50 weeks/yr)(10 shifts/week) (8 hr(shift) = 4000 hr/yr

Total hourly labor rate= $30 + $15= $45/hr

total labor cost = (1956 workers) (2000 hr/wrk-yr) ($45/hr) = $176,040,000

LAbor cost in trim-chassis-final per car= 176,040,000/200,000 = $880.20/car
