Figure 4
The image contains three separate line graphs. The first graph, labeled SV1F_Y, shows a line that fluctuates between 1980 and 2020, with values ranging from approximately -14.8 to -12.4. The second graph, labeled SV2F_Y2, displays a line that generally declines from around 0.95 in 1980 to about 0.60 in 2020. The third graph, labeled SV3F_TI, presents a line that rises and then stabilizes, with values ranging from approximately 0.04 to 0.24 between 1980 and 2020. All values are approximated.Time-varying parameter estimates for LY, LY2 and LTI
