In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

Using administrative data for West Germany, this paper investigates whether part of the urban wage premium stems from fierce competition in thick labour markets. We first establish that employers possess less wage-setting power in denser markets. Local differences in wage-setting power predict...

This paper revisits the question of how brain drain affects the optimal education policy of a developing economy. Our framework of analysis highlights the complementarity between public spending on education and students' efforts to acquire human capital in response to career opportunities at...

This paper examines the links between the internationalization mode of firms and market imperfections in product and labor markets. We develop a framework for modelling heterogeneity across firms in terms of (i) product market power (price-cost markups), (ii) labor market imperfections (workers'...

This paper proposes a simple general equilibrium model with labour market frictions and an imperfect financial market. The aim of the paper is to analyse the transitional dynamics of unemployment and vacancies when financial constraints are in place. We model the financial sector as a...

We use matched employer-employee data and firm balance sheet data to investigate the importance of firm productivity and firm labor market power in explaining firm heterogeneity in wage formation. We use a linear regression model with one interacted high dimensional fixed effect to estimate...

A pre-condition for employer learning is that signals at labor market entry do not fully reveal graduates' productivity. I model various distinct sources of signal imperfection such as noise and multi-dimensional types and characterize their implications for the private return to skill...

We investigate wage differences between newly hired and incumbent employees. We show in a formal model that when employees care for wages as well as match-specific utility, incumbents earn less than new recruits if and only if firm-specific human capital is not too important. The existence and...
