In order to investigate whether this improper integral converges, we must split the integral about any point within the interval and view each integral as a limit. Since $e^0 = 1$, we split the integral about $x = 0$ (for convenience). $2 \int_{-\infty}^{0} \frac{e^x}{1 + e^{2x}} dx = 2 \int_{-\infty}^{0} \frac{e^x}{1 + e^{2x}} dx + 2 \int_{0}^{\infty} \frac{e^x}{1 + e^{2x}} dx$ $= \lim_{c \to -\infty} 2 \int_{c}^{0} \frac{e^x}{1 + e^{2x}} dx + \lim_{c \to \infty} 2 \int_{0}^{c} \frac{e^x}{1 + e^{2x}} dx$ Evaluate the integrals $\int_{c}^{0} \frac{e^x}{1 + e^{2x}} dx$ and $\int_{0}^{c} \frac{e^x}{1 + e^{2x}} dx$. These will require a $u$-substitution of $u = e^x$, $du = e^x dx$. $\int_{c}^{0} \frac{e^x}{1 + e^{2x}} dx = $ $\int_{0}^{c} \frac{e^x}{1 + e^{2x}} dx = $

Economists argue that instead of regulating behavior through command-and-control policies, the government could use market-oriented tools to achieve environmental goals. One such instrument is the marketable permit program. Which of the following statements about the marketable permits program is false? Select the best answer. Answer 2 Points Keypad Keyboard Shortcuts In an environmental policy that uses marketable permits, the government "caps" the total emissions (by issuing a fixed number of permits) and then allows firms to trade. Firms that can only lower pollution at a high cost will have a high willingness to pay for pollution permits. Firms that can only lower pollution at a high cost will sell their permits to help defray the high cost of abatement. The government could design a tradeable pollution permits system to reduce total emissions over time. It would reduce the number of permits allotted to firms in the program each time period.

It's a mature company, but future EPS and dividends are expected to grow with inflation, which is forecasted at 2.75% per year. $P_0 = \frac{D_1}{r-g} = \frac{1.35 \times (1.0275)}{0.095 - 0.0275} = 20.35$ a. What is Pharmecology's current stock price? The nominal cost of capital is 9.5%. b. Redo part (a) using forecasted real dividends and a real discount rate.
