Definition, Validation And Comparison Of Two Population Models For Austria, Martin Bicher, Barbara Glock, Florian Miksch, Niki Popper, Günter Schneckenreither
UBT International Conference
In this work we present two structurally different mathematical models for the prognostic simulation of Austria’s population: A time-continuous, macroscopic system dynamics approach and a time-discrete, microscopic agent-based approach. Both models were developed as case studies of a series of population concepts in order to support models for decision-support in Austria’s health care system. In the present work we want to focus on the definition, the parametrisation as well as especially the validation process of both population-models. The latter was of special interest as it included a cross-model validation with Statistics Austria’s own prognostic model SIKURS.

Credit Information System In Albania, Valbona Çinaj, Bashkim Ruseti
UBT International Conference
The booming lending period and many lenders (16 banks and 21 non-bank financial Institutions in Albania) brought about unprecedented competition in credit markets within Albania. Economists usually view lending and competition favorably, but in Albania resulted in a number of unforeseen non-performing loans. Findings report increased problems of borrower over-indebtedness, reduced loan repayment incentives, and growing debts for lenders (Campion 2001; McIntosh and Wydick 2005). The weakening performance of lenders is due in part to the absence of information sharing in these markets. Because growing numbers of lenders (banks and non-bank financial Institutions in Albania) increase the level of asymmetric …
