- It has been widely reported that an increasing number of US women have joined the labor force during the last few decades Directions: Double click on the graph to the night Select Multiple Time Series Data For Y Axis1 select the labor force participation rate of men, and for Y Axis2 select the labor force participation rate of women. After selecting these senes the data will be plotted in the graph According to data shown on the graph on the right, it is clear that the labor force participation rates for men and women in the US OA tended to converge over almost the entire period OB. remained constant during the entire period of 1970-2004 OC. neither tended to converge nor tended to diverge during almost all of the period of 1970-2004 OD. tended to diverge during the entire period This question:(s) possible 4 100- 90- 80- 70- 60- 40- Labor Force Participation Rate - Women 30- Labor Force Participation Rate - Men 20- Labor Force Participation Rate - Women 10- -100 -90 -80 -70 60 -50 --40…Explain why it is important that time-series variables are ‘stationary’.

However, in terms of real value — which refers to the constant price using the Consumer Price Index with the base year 2014 as the deflator — annual growth rate is 3.9% for the same period, mentioned on its Household Expenditure Survey Report 2020. a) Suppose that consumer spending initially rises by RM5 billion for every 1 percent rise in household wealth and that investment spending initially rises by RM20 billion for every 1 percentage point fall in the real interest rate. Also, assume that the economy’s multiplier is 4. i. If household wealth falls by 5 percent because of declining house values, and the real interest rate falls by two percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level? ii. In what…
- What is meant by the seasonal adjustment of a time series? Explain why government agencies expend a large amount of effort on the seasonal adjustment of economic time series.The number of pending corporate fraud cases in federal court stood at 545 at the beginning of 2008 (t = 0). The number of cases had grown to 726 at the beginning of 2012. Assume the growth has been approximately linear. Develop the equation of the line that describes this linear growth. Then use that linear equation to estimate the number of cases pending at the beginning of 2014, assuming that the linear growth continues at the same rate.Economic time series are maintained and published by some government agencies such as the Census Bureau and the Bureau of Labor Statistics, and they use time series decomposition.
