Refer to the quarterly value of Gross Domestic Product (GDP in billions of currentdollars) in China from 2021q1 to 2023q4. You are going to analyze GDP by an additivemodel with a trend component (Tt) and a seasonal component (St), and forecast GDPusing the seasonal decomposition method.YearQuartertGDP (Y₁)CM(4)Detrended202111249202228284.93329128.8??4432589.9??20221527034.4??2629244.7??3730794.2??4833399.1??20231928442.3??21030829.3??31131997.641234789a.

Calculate the seasonal factors for each quarter with a zero mean, by first obtainingthe detrended revenue series from t = 3 to 10.c. In this seasonal decomposition method, why is it necessary to use moving averagesto process time series data first? How about using moving average of order 5?

Statistics Denmark monitors the development of economic variables and measures e.g. productivity development.In general, it is one of the laws of economics that employee productivity determines the ability of employers to pay employees wages. The higher the productivity (per capita output), the higher the wages that can be paid. In a recession, such as Covid, companies are generally reducing their use of labor. The latest statistics show the following: In the third quarter of 2020, labor productivity growth in Denmark was 2%. This increase alone does not say much, but is considered to be able to reflect an increase in productivity following a contraction in labor input. a. Show the relationship between production and labor use in the short term and at the same time explain with a picture what can cause the growth of productivity. b. What is happening to marginal production at the same time? c. Show how wages develop if companies keep marginal costs fixed in the above circumstances…

Rubax, a U.S. manufacturer of athletic shoes, estimates the following linear trend model for shoe sales: Qt = a+bt+c1D1+c2D2+c3D3Where, Qt = sales of athletic shoes in the t-th quartert = 1, 2, . . . . , 28 [2011(I), 2011(II), . . . . , 2017(IV)]D1 = 1 if t is quarter I (winter); 0 otherwiseD2 = 1 if t is quarter II (spring); 0 otherwiseD3 = 1 if t is quarter III (summer); 0 otherwiseThe regression analysis produces the following results: Is there sufficient statistical evidence of an upward trend in shoe sales? explain Do these data indicate a statistically significant seasonal pattern of sales for Rubax shoes? If so, what is the seasonal pattern exhibited by the data? Using the estimated forecast equation, forecast sales of Rubax shoes for 2018(III) and 2019(II).
