The purpose of this study is twofold. First, it aims to provide the estimates of returns to schooling using consistent methodology and comparable set of data for a relatively long time horizon for a country undergoing economic transition and accession process into European Union, 1995-2017. Secondly, using the Mincer (1974) methodology of wage regressions it aims to verify if returns to schooling are pro-cyclical or counter-cyclical. Returns to schooling are linked to the evolution of unemployment rate on a regional level. Estimated earnings functions suggest that returns to schooling were increasing in Poland until 2006 and declining afterwards unveiling the supply side effects domination. The estimates show that an increase in unemployment rate by 1 percent leads to an increase of return to additional year of schooling roughly by 0.008 percentage points.

转型经济中商业周期内私立学校收益的演变

这项研究的目的是双重的。首先，它的目的是为一个经历经济转型和加入欧盟进程的国家（1995-2017年）在相对较长的时间范围内，使用一致的方法和可比较的数据集，提供入学回报的估算。其次，使用Mincer（1974）的工资回归方法，其目的是检验入学回报是顺周期的还是逆周期的。上学的回报与区域一级失业率的演变有关。估算的收益函数表明，波兰的教育收益在2006年前一直在增长，此后由于供给方面的副作用占主导地位而下降。估计数字表明，失业率提高1％，导致返校一年的收益增加大约0。
