Can anybody please help me to understand what are the differences between Simultaneous Equation Model and Structural Equation Model (SEM)? It will be great if somebody can provide me some literature on it.

Also, is there any literature where SEM has been used in timeseries context? The literatures I'm getting are mostly explained SEM in cross-sectional data context.

Thank You!
