We compare the statistical performance of static model, finite distributed lag model, exponential feedback model and different DCS count panel data models. For DCS we consider random walk and quasi-autoregressive formulations of dynamics. We use panel data for a large cross section of United States firms for period 1979 to 2000. We estimate models by using the Poisson quasi-maximum likelihood estimator with fixed effects. The estimation results and diagnostics tests suggest that the statistical performance of DCS-QAR is superior to that of alternative models.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 Españaresearch and developmentcount panel datadynamic conditional scorequasi-maximum likelihoodworking paperC33C35C51C52O3open accessDT/0000001478
