The model of the wage bargaining constitutes a framework for calculation of the NAWRU in Poland. The approach used in the paper let me trace changes of the natural unemployment rate in Poland in the context of structural changes in the economy in the last decade. Moreover, I introduced the endogenous equilibrium rate into the existing macroeconomic model -ECMOD. It allowed me to simulate NAWRU behavior after economic shocks. Simulation results shed some light on channels and speed of adjustment of the modelled economy. Interestingly, when NAWRU is tied to the stock of capital, relative prices and fiscal variables, the model is able to replicate high degree of the unemployment persistence.
There is an arising consensus on the empirical importance of temporary labour migration. In acknowledgement of this fact the present overview summarizes literature that deals with drivers and effects of temporary labour movements. The overview sets together relevant elements of migration initiation and perpetuation, return migration and international trade theories. It also complies conclusions from a growing body of empirical literature on re-emigration to the country of origin, remittances and on the behaviour of temporary versus permanent immigrants. Distinguishing temporary from permanent labour migration should help to explain the dynamics of the actual international labour movements and to understand their impact on economies.
