Assistant Professor Xirong Lin has published a paper online in Journal of Econometrics, a first-tier journal as listed by SUFE. The paper entitled “Identification of Semiparametric Model Coefficients, With an Application to Collective Households” was co-authored with Arthur Lewbel (Boston College).
We prove identification of coefficients for a set of semiparametric specifications that are related to multiple index models. Potential applications of these results include models of observed heterogeneity in production functions and in consumer demand systems. We then generalize these results to identify a class of collective household consumption models. We extend the existing literature by proving point identification, rather than the weaker generic identification, of all the features of the collective household model, including price effects. We estimate the model using Japanese consumption data, and find substantial variation in resource shares and indifference scales across households of different sizes.
