In my research, I use a wide range of econometric models to model a broad spectrum of issues. I am particularly interested in panel data models and all methods related to the problem of endogeneity. Panel data allow the analysis of the behavior of multiple entities over several periods of time, with each entity being observed over several periods. These data enable drawing more conclusions than cross-sectional or time series data. Panel models are applicable in many areas of economics, such as enterprise analysis, political economy, health economics, and safety sciences. I am especially interested in the possibility of using multiequation models for panel data, where we can simultaneously explain several phenomena.
