Current Research Topics on Panel Econometrics

Convergence                                      

Testing convergence has been an important task in many areas of Economics and Social Science. Understanding the notion of the convergence is important. I have established the notions of relative and weak sigma convergences. The so-called Beta-convergence is ambiguous and does not reflect the convergence concept correctly.

Identifying Common Factors

Surprisingly, common factors explain more than half of variations of macro panel data. This important component has been ignored. Identifying these unknown common factors is the first step to understand empirical issues of interest.

Econometrics on Experimental Economics

Experimental economists always wonder whether or not there are better econometric or statistical methods. Here are a couple of theoretical attempts to help experimental economists.
