The proceedings from the 15th EDAMBA conference, which took place at the University of Economics in Bratislava on 22nd November 2012 have been prepared as a joint refereed publication of participants presenting their papers at the conference. The aim of EDAMBA as an organisation is to promote the exchange of information, to enhance the mobility of PhD candidates, to promote research cooperation and to increase the quality of PhD programmes and to create an environment of excellence with a European perspective while pursuing the existing diversity.
The paper focuses on the issue of price endogeneity and its relation to various micro-economic characteristics of households. The modeling of intergroup dynamics of the price index for food and nutrition among household groups in relation to the amount of expenditure on food per person confirms the relevant hypothesis. This modeling requires the access to the information in the household surveys data, available only in the RLMS. The mechanism of data consolidation of RLMS and Households' budgets survey by Rosstat (VOBDH) is proposed and can also be used for price heterogeneity incurporation.
