Comparative Statics in Dynamic Programming Models with an Application to Job Search


This paper presents a technique for qualitative comparative statics analysis in dynamic programming models. Let the value function v be the fixed point of a contraction mapping which depends differentially on some exogenous parameter theta. Then the derivative of v with respect to theta exists and is also the fixed point of a contraction mapping. Since this derivative is the fixed point of a contraction mapping its qualitative properties can be investigated using mathematical induction. This comparative statics methodology is illustrated with an application to a model of job search.

An Overall Perspective

Pages-from-2019-Calmfors-Gassen---Integrating-Immigrants-into-the-Nordic-Labour-Markets.gif

Denmark, Finland, Norway and Sweden face similar problems of integrating large groups of immigrants, especially low-educated ones from outside the EU, into their labour markets. In this volume, edited by Lars Calmfors, IFN, and Nora Sánchez Gassen in cooperation with researchers from across the Nordic Region analyse how labour market integration of immigrants can be promoted. 

About the book

Events

Seminars organized by IFN

 

To present ongoing research informal brown-bag seminars are held on Mondays at 11:30 am. This is an opportunity for IFN researchers to test ideas and results.

Academically oriented seminars are most of the time held on Wednesdays at 10 am. At these events researchers from IFN and other institutions present their research.

In addition, IFN organizes seminars open to the public. Topics for these are derived from the IFN research.
