“…If 3 is correlated with 4 , CPC will be endogenous. Our proposed simultaneous model closely resembles the triangular system in standard econometric textbooks (Lahiri andSchmidt 1978, Greene 1999). To see this more clearly, CPC is modeled as exogenously determined (modeled as the advertiser's decision and a function of the advertiser's past performance with the same keyword and other keyword-related characteristics).…”

“…CPC, in turn, affects the search engine's ranking decision, and finally Rank affects both clickthrough and the conversion probabilities. As shown in Lahiri and Schmidt (1978) and discussed in Greene (1999), a triangular system of simultaneous equations can be identified without any further identification constraint such as nonlinearity or correlation restriction. In particular, the identification of such a triangular system comes from the likelihood function.…”

“…Econometric Speci cation Lahiri and Schmidt (1978) recommend applying FIML or 3SLS for the estimation of a triangular system with cross-equation correlation, manifesting itself in the form of a non-diagonal variance-covariance matrix Σ of the disturbances of the system. For the estimation of systems such as the one outlined above, Kelejian and Prucha (2004) propose a feasible generalized spatial three stage least squares (FGS3SLS) estimator, which can additionally correct for spatial correlation.…”

“…We note that, in general terms, Equations (8)-(11) represent a triangular system with a nondiagonal disturbance covariance matrix (if it were not for the assumption of simultaneity, the model could be regarded as recursive). In such cases, 3SLS estimation is preferred (Lahiri and Schmidt 1978). To our knowledge, empirical applications based on this particular type of model specification have not been published.…”
