A number of advances have taken place in panel data analysisduring the pastthree decades and it continues to be one ofthe most active areas of research. This volume contains 13significant contributions focusing on modelling strategies,data issues, theoretical analysis and applications. Appliedeconometrics papers on the economics of labor, health,telecommunications, finance and macroeconomics are providedas well as a survey of recent theoretical developments inpanal data analysis. Contributors include both well knownscholars and younger researchers from Australia, Canada,Europe and the United States of America.A number of advances have taken place in panel data analysisduring the pastthree decades and it continues to be one ofthe most active areas of research.
