The aim of the article is to examine the degree of the long-run interest rate convergence in the context of Poland's joining the EMU. In this perspective, it is frequently argued that the expectations of Poland's participation in the EMU should manifest themselves in long-run interest rate...

In many countries the fiscal tension associated with the global financial crisis brings about the discussion about unprivatizing the social security system. This paper employs an OLG model to assess ex ante the effects of such changes to the pension reform in Poland from 1999 as implemented in...

Pension system reforms involve fiscal consequences. In practice, a variety of fiscal closures may be implemented, while not all of them involve the same extent of distortions. This paper develops an overlapping generations model to analyze the case of a shift from pay-as-you-go defined benefit...

The overlap problem is crucial in propensity score matching. Recently, Crump et al. (2009) showed that trimming provides a simple and robust solution to the overlap problem. In this study, we use a simulation approach to show that trimming is inferior to the caliper mechanism. We show that in...

Unregistered employment poses two types of challenges to the researchers: (i) reliably evaluating the wage differential between formally and informally employed and (ii) accounting for the push and pull factors in general and the effects of business cycle in particular. We address the former...

Decomposability of multidimensional inequality indices by attributes is considered a highly desired property. Naga and Geoffard (2006) provided for it in case of three bivariate indices. To this end, they introduced the notion of a copula function into inequality measurement theory which, as a...

This paper compares option pricing models, based on Black model notion (Black, 1976), especially focusing on the volatility models implied in the process of pricing. We calculated the Black model with historical (BHV), implied (BIV) and several different types of realized (BRV) volatility...

Increasing the share of vocational secondary schooling has been a mainstay of development policy for decades, perhaps nowhere more so than in formerly socialist countries. The transition, however, led to significant restructuring of school systems, including a declining share of vocational...
