Historically, public opinion surveys have relied on the ability to adjust their datasets using a core set of demographics — sex, age, race and ethnicity, educational attainment, and geographic region — to correct any imbalances between the survey sample and the population. These are all variables that are correlated with a broad range of attitudes and behaviors of interest to survey researchers. Additionally, they are well measured on large, high-quality government surveys such as the American Community Survey ACS , conducted by the U. Census Bureau, which means that reliable population benchmarks are readily available. But are they sufficient for reducing selection bias 6 in online opt-in surveys? Two studies that compared weighted and unweighted estimates from online opt-in samples found that in many instances, demographic weighting only minimally reduced bias, and in some cases actually made bias worse.

Why or why not? All capital sources — common stock, preferred stock, bonds and any other long-term debt — are included in a WACC calculation. All else equal, the WACC of a firm increases as the beta and rate of return on equity increases, as an increase in WACC notes a decrease in valuation and a higher risk. Thus, since the WACC is the minimum rate of return required by capital providers, the managers in the company should invest in the projects which generate returns in excess of WACC. The book values are historical data, not current ones; on the contrary, the market recalculates the values of each type of capital on a continuous basis, therefore, market values are more appropriate.
