Abstrakty

Celem artykułu jest przybliżenie zagadnień związanych z modelami poszukiwań i dopasowań oraz zobrazowanie ich potencjalnych możliwości w zakresie analizy rynków pracy. W sekcji pierwszej tekstu skrótowo przedstawiono rys historyczny wspomnianych modeli oraz dwa ich główne kierunki rozwoju. Następnie zaprezentowano jeden z najstarszych, lecz i najszerzej w literaturze omawianych modeli: model sekwencyjnego poszukiwania pracy. W drugiej sekcji tekstu szczegółowo przedstawiono podstawowy model Mortensena i Pissaridesa. Najpierw omówione są założenia teoretyczne, następnie mechanizm poszukiwań i dopasowań, warunki tworzenia i destrukcji miejsc pracy oraz powiązane z nimi ustalenie płac na rynku (Nash Bargaining Solution - NBS), co w efekcie prowadzi do ustalenia stanu stacjonarnego modelu (steady-state equilibrium). W kolejnej części tekstu, na podstawie literatury, zostaje omówione i przedstawione zastosowanie modelu w analizach rynku pracy. Autor zwraca uwagę na zagadnienia najbliższe jego zainteresowaniom badawczym - na modelowaniu cyklu gospodarczego i polityki rynku pracy. W tych dwóch aspektach omówione zostają również potencjalne problemy i krytyka, z jaką model Mortensena i Pissaridesa się spotkał.

The aim of this paper is to explain the principles of operation of search and matching models and illustrate their research capabilities for the analysis of labour markets. The first part of the paper is a short historical review of the two models, and a presentation of the oldest, but also most frequently referred to in literature sequential job search model. The second part describes in detail the basic Mortensen-Pissarides (MP) model operating in a frictional environment. It begins with some theoretical assumptions, followed by a presentation of the matching technology, job creation and job destruction conditions and related to them wage determination mechanisms (Nash Bargaining Solution). Finally, a steady-state equilibrium is determined. In the third part, possible applications of the MP model to labour market analysis is presented. The main focus is put on the real business cycle (RBC) and the labour market policy (LMP). Weaknesses in performance of the MP model in those two aspects (RBS, LMP) are also discussed.(original abstract)
