Economists have known for many years that lagged dependent variables can cause major estimation problems, but researchers in other disciplines are often unaware of these issues. The basic argument is pretty straightforward. Betancourt, R. and Kelejian, H. (1981). Lagged endogenous variables and the Cochrane-Orcutt method. Econometrica, 49, 1073–1078.

Variable X1 is endogenous and therefore it is Across the social sciences, lagged explanatory variables are a common strategy to confront challenges to causal identiﬁcation using observational data. We show that “lag identiﬁcation”—the use of lagged explanatory variables to solve endogene-ityproblems—isanillusion: laggingindependentvariablesmerelymovesthechannel Se hela listan på mathworks.com Lagged y will be correlated by construction with ηand with lagged v, but it may also be correlated with contemporaneous v if v is serially correlated, which is not ruled out by (2). Thus, lagged y is eﬀectively an endogenous explanatory variable in equation (1) with respect to both ηand v. Lagged endogenous variable Definition from Society & Culture Dictionaries & Glossaries.

Exogenous variables (Ti and Zi) are exogenously given outside of the model.

In other words, an endogenous variable is variables and lagged exogenous variables are referred to as the predetermined variables since their values are determined outside the model. Simultaneous equations with lagged endogenous variables In short, current exogenous, lagged exogenous, and lagged endogenous variables are deemed predetermined; their values are not determined by the model in the current time period. In 1970, Fair worked on various methods for estimation of simultaneous equation models with lagged endogenous variables and first order serially correlated errors. variables, lags of the endogenous dependent variable, as well as unobservable individual-specific effects that may be correlated with the observed covariates in an unspecified way. For the binary logit model with the dependent variable lagged only once, Chamberlain (1993) has shown that, if individuals are observed LAGGED ENDOGENOUS VARIABLES 1075 by replacing p by pj, or from (4b) by replacing b, and b2 by blj and b2j, can be expressed as etj= Et - I(Pj-P)+ (Xt -pjXt-1)(blj- bl) + (yt Yt - lPj Yt-2)(b2j-b2)-For future reference we note a result which is not difficult to show, namely N (5) plim eTI/N= o + A, N-*oo t=l I think (though I am not certain) that I can use -xtabond2- to estimate each equation separately to overcome the consistency issue associated with lagged endogenous variables.
