Meta-analysis helps researchers do which of the following: a. Investigate the effects of minimum wage increases through controlled laboratory experiments b. Infer the effects of increases in the minimum wage by averaging the results of other studies c. Generally find elasticity estimates for labor demand to be highly elastic d. Examine changes in the minimum wage in multiple countries I think answer is b. according to the literature below: "Research since 2007, however, has reported conflicting findings. Some studies use “meta-analysis,” averaging across a set of studies to draw conclusions. For example, Doucouliagos and Stanley (2009) report an average elasticity across studies of −0.19, consistent with earlier conclusions, but argue that the true effect is closer to zero; they suggest that the biases of authors and journal editors make it more likely that studies with negative estimates will be published. However, without strong assumptions it is impossible to rule out an…

Technicians use moving-average lines to detect changes in trends by observing the interaction between the price of an asset and its moving average over a specific period. Consider a stock whose price data over the past 10 days are as follows: Day 1 2 3 4 5 6 7 8 9 10 Stock Price ($) 54.50 54.25 55.75 56.50 57.25 56.00 54.75 53.25 52.50 53.00 5-Day Simple Moving Average ($) Trend Assume a simple moving average (SMA) is calculated over a 5-day period. Calculate the SMA for each day, and based on the SMA, identify any potential changes in the trend during the 10-day period.
