Comment certains systèmes se maintiennent-ils malgré un environnement incertain et changeant ? Cette question reste peu explorée dans la littérature, en particulier en ce qui concerne la compréhension des efforts des acteurs pour reproduire des croyances et des schémas de pensée. Dans...

L‟institution, par définition, reflète une notion de persistance. Elle cadre durablement la pratique des acteurs à travers un ensemble d‟éléments réglementaires, normatifs et cognitifs. Par ailleurs, cette persistance n‟est pas le résultat d‟un pur effet institutionnel. Elle...

This paper analyzes the effect of firing costs on aggregate productivity growth. For thispurpose, a model of endogenous growth through selection and imitation is developed. It isconsistent with recent evidence on firm dynamics and on the importance of reallocation forproductivity growth...

This paper analyzes the effect of Product Market Regulation (PMR) on unemployment in asearch model with heterogeneous multiple-worker firms. In our setup, PMR modifies thedistribution of firm productivities, thereby affecting the equilibrium rate of unemployment...

Using data on product-level prices matched to the producing …rm’s unit labor cost, wereject the hypothesis of a full and immediate pass-through of marginal cost. Since wefocus on idiosyncratic variation, this does not …t the predictions of the Ma´ckowiak andWiederholt (2009) version of the...

Given the political and public interest in rising industry concentration in developed economies, researchers have been working on uncovering underlying mechanisms and implications. Various causes of concentration have been proposed, although rarely tested in a comprehensive model. We study five...

The research measures the driving force of innovation in economic structure transition. In order to change the pattern of economic development, China is implementing a strategy of innovation-driven development. China's capacity of innovation has been increasing, especially since 2012, and...

This paper uses Nash equilibrium reversion as an optimal tool for clearing dynamic prices and wages. Various exogenous competitive rigidities determine the balanced growth path of the efficiency wage and the outcome of repeated household/firm wage bargaining decisions. A location model is used...

This paper introduces a New Keynesian multi-sector industry model that integrates firm heterogeneity, entry, and exit dynamics, while considering energy production from both fossil fuels and renewables. We investigate the effects of a sustained increase in fossil fuel prices on sectoral size,...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing as its productivity increases....
