Proceedings of the International Scientific Conference for Doctoral Students and Young Researchers EDAMBA 2012
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.
In this paper the public-private wage gap is estimated by means both of the OLS and the quantile regression, which will provide a more complex picture of the distribution of the public-private sector wage gap. The author finds the existence of significant public-private wage gap (about 30%) considering both observable and unobservable characteristics of workers and jobs. Using the decomposition based on quantile regression helps to answer the question about the nature of the wage differences. The author comes to the conclusion that the main reason for the gap is the institutional mechanisms of public sector wages in Russia. The analysis is based on the data from Russian Longitudinal Monitoring Survey (RLMS-HSE) 2000-2010.
Most of existing scoring systems are based on binary choice models with sample selection. This setting does not allow for up-to-date information about loans to be used and a lot of observations becomes lost. In the paper a model of binary choice with sample selection is extended to the case of many periods. This extension allows for defaults to be modeled for each period that solves the problem of lost observations. This setting also can be used to estimate the effectiveness of existing scoring system of a bank. The model is estimated using data granted by one of commercial banks of Nizhny Novgorod. Sample consists of observations from January 2009 to March 2012.
Relation between the informal employment and job satisfaction is investigated in the paper. Informal employment takes rather big place in Russian economy, what makes research of the mechanism of the informal sector of the labor market functioning very relevant. Ordered choice models with sample selection correction were estimated on the Russia Longitudinal Monitoring Survey of HSE (RLMS-HSE) data. The key result of the paper is that subjective well-being is not determined by employment status itself, crucial is conditions of choice. Individuals, who came to the informal sector because of their own choice, treat their job as well as workers' with the registered employment. So, they have no incentives for seeking to formalize their status, which could mean further growth of the informal sector.
