Research Areas

There are two main directions in my research: Statistics and Applications in Economics, Social and Engineering Sciences. In Statistics, I use models to make analyses of discrete and categorical data, truncated and censored data-, panel data- and event oriented transition data. I am mainly interested in the methodological problems of Panel- and Transition Data Models, such as modelling the fixed effects, duration dependency, unobserved heterogeneity, endogeneity of time varying variables and large sample properties of estimators.

In my applied research, I have employed statistical methods and techniques in the areas of Economic-Demographics, Labour Economics, Social Policy, Defence and Peace Economics, Environmental Problems, Health and Engineering. Over time, these studies are concentrated on the determinants, dynamics and consequences of fertility; social assistance dependency; lone motherhood; unemployment; disability; retirement; immigration; discrimination against older men; arms import; dynamics of wars; Human Development Index; Global Peace Index; solar radiation; wind energy; forecasting of environmental problems; and morbidity and mortality of cancer sickness. All methodological problems of the statistical models of the first part of my research are empirically investigated in connection with the issues in the second part.
