We show an introduction to the history of panel-data econometrics, the most common models and their uses in the Mexican context. In the first part, we show the evolution of panel-data econometrics from the nineteenth century to the beginning of the twentyfirst one.In the second part, we describe the models with fixed, random and dynamic effects. In the subsequent parts, we show some trends regarding the studies that have used panel-data and regarding the use of the models in certain areas of knowledge (social sciences, macroeconomics, microeconomics, international economics, finance, public finance). We analyze these trends with the articles included in the REDALYC database for the period 2000-2013.
