Shadow Employment In Post-Transition - A Matter Of Choice Or No Choice?, Stanislaw Cichocki, Joanna Tyrowicz Jan 2010

Shadow Employment In Post-Transition - A Matter Of Choice Or No Choice?, Stanislaw Cichocki, Joanna Tyrowicz

Joanna Tyrowicz

According to a dualistic view, shadow employment may follow from two main labour market failures: (i) official market labour taxation distortions make it ineffective for some agents to engage in registered employment due to a tax wedge; or (ii) for some workers regular employment may be unattainable do to some high access costs or demand constraints, which results in seeking earning opportunities beyond the boundaries of the official labour market. Whereas in the first case revenues from unofficial employment should be higher than the corresponding official ones (tax evasion hypothesis), in the alternative explanation labour market tightness seems to be ...

Is The Impact Really That High? The Effect Of Fdi In Transition, Jan Hagemejer, Joanna Tyrowicz

Joanna Tyrowicz

Literature is not clear on the effect of FDI on the economic performance in hosting countries. The analysed eects include productivity, propensity to export, access to financial markets, etc. Although foreign subsidiaries usually perform better than the average of the hosting economies, sometimes the selection eect is found to be considerable. The analysed eects In this paper we use a unique dataset based on accounting annual reports to the statistical authorities by all medium and large Polish enterprises over a period 1997-2006.

Labour Market Racial Discrimination In South Africa Revisited, Joanna Tyrowicz, Maciej Szelewicki Jan 2009

Labour Market Racial Discrimination In South Africa Revisited, Joanna Tyrowicz, Maciej Szelewicki

Joanna Tyrowicz

Discrimination is a significant issue in labour market economics across developed as well as developing countries. In this paper we inquire the actual size of wage discrimination in the Republic of Soutn Africa, accounting for large differences in endowments. We apply the Oaxaca-Blinder decomposition as well as propensity score matching to adequately determine the size of the pay gap. Although the size of the absolute racial pay gap is enormous, amounting for more than 500%, the actual estimated effect non-attributable to other factors ranges between 45%-55%. This estimator however assumes homogenous discrimination across the wage distribution, while data suggest ...
