Abstract:
Purpose: This paper tries to identify the wage gap between informal and formal workers and tests for the two-tier structure of the informal labour market in Poland. Design/methodology/approach: I employ the propensity score matching (PSM) technique and use data from the Polish Labour Force Survey (LFS) for the period 2009–2017 to estimate the wage gap between informal and formal workers, both at the means and along the wage distribution. I use two definitions of informal employment: a) employment without a written agreement and b) employment while officially registered as unemployed at a labour office. In order to reduce the bias resulting from the non-random selection of individuals into informal employment, I use a rich set of control variables representing several individual characteristics. Findings: After controlling for observed heterogeneity, I find that on average informal workers earn less than formal workers, both in terms of monthly earnings and hourly wage. This result is not sensitive to the definition of informal employment used and is stable over the analysed time period (2009–2017). However, the wage penalty to informal employment is substantially higher for individuals at the bottom of the wage distribution, which supports the hypothesis of the two-tier structure of the informal labour market in Poland. Originality/value: The main contribution of this study is that it identifies the two-tier structure of the informal labour market in Poland: informal workers in the first quartile of the wage distribution and those above the first quartile appear to be in two partially different segments of the labour market.

Abstract:
This paper addresses the issue of household demand for services in Poland when informal sector is taken into consideration. The aim of the study is threefold: (i) to investigate the factors influencing households expenses for services, (ii) to find the determinants of households’ tax strategy (choice between acquiring services on regular labour market or not), (iii) to investigate the differences between the factors that influence the expenses for formal versus informal services. Two-step Heckman selection model is used to account for the selection into buying household services. Lee’s (1983) procedure is adopted to control for the selection into the particular choice of tax strategy when purchasing household services. The decision whether to buy household services and whether formally or informally is modelled as a sequential choice and estimated by bivariate probit with selection. An important novel feature of the model used is the inclusion of variables that capture social norms and personal attitudes toward tax evasion. The study concludes that factors influencing expenses for services are positively related to financial situation of households, education and age of household head. The probability of avoiding taxes is higher for lower income households, households with more than one member and for those where a positive attitude toward informal employment is expressed. The impact of determinants of expenses for formal and informal services separately is comparable. Only household structure has the opposite effect on expenses for formal services versus informal ones.
