Es erscheint keine Fehlermeldung.

Die lag Variablen werden aber nicht richtig zu geordnet.

Das ist mir unklar, da musst du ein Datenbeispiel posten und es aufzeigen, was hier schief läuft.

Eigentlich müsste hinter 2000 jeweils immer ein "." stehen, weil der Datensatz kein Jahr 1999 beinhaltet.

Ebenso verhält es sich für die anderen Jahre. 2002 hat nicht die Werte von 2001.
Dabei ist es egal ob es sich um "AcquirorNation" oder "TargetNation" handelt.

Code: Alles auswählen

bysort AcquirorNation (year): gen lag1 = ln_Number_of_Deals_per_Year_A[_n-1]
bysort TargetNation (year): gen lag2 = ln_Number_of_Deals_per_Year_T[_n-1]
