  • Regional Development in a Well-Being Economy: The Case of Lithuania
    Willem K. Brauers (University of Antwerp)
    Co-authors: R. Ginevicius, R. Bisdorff
    Abstract:
    Willem Karel M. Brauers 1) and Romualdas Ginevicius2) 1) Faculty of Applied Economics and Institute for Development Policy and Management, University of Antwerp, Belgium 2) Department of Enterprise Economics and Business Management, Vilnius Gediminas Technical University, Vilnius-40, Lithuania ABSTRACT The computation of a Regional Income, being an exponent of the welfare economy, is not sufficient for the measurement of the well being of a regional population. The well-being economy goes further. In the well-being economy, each individual would have to feel good concerning material wealth, health, education, all kind of security and concerning the environment. With other words, multiple objectives have to be fulfilled. Moreover, these different multiple objectives are expressed in different units. Weights are most of the time used to equalize these different units. However, introduction of weights means also introduction of subjectivity. In order to avoid this dilemma, the internal mechanical solution of a ratio system, producing dimensionless numbers, is preferred. In addition, the use of the obtained ratios creates the opportunity to come to a non-subjective reference point theory. This double approach is called the MOORA Method (Multiple Objectives Optimization by Ratio Analysis). The choice and importance of the objectives is also non-subjective if all stakeholders involved come to an agreement. This theory is applied on the different regions of Lithuania. A redistribution of income has to take place from the well being Lithuanian regions to the poorer regions, but under limiting conditions and for well defined and eventually controlled projects.
