This paper examines whether growth regressions should incorporate dualism and structural change. If there is a differential across sectors in the marginal product of labour, changes in the structure of employment can raise aggregate total factor productivity. The paper develops empirical growth...

Average wages are considerably lower in agriculture than in the other sectors. We document this fact for thirteen countries ranging from rich (Canada, U.S.) to poor (India, Indonesia). We develop a measure of human capital that accounts for the selection of workers with different unobserved...

This document describes and discusses a new supply side framework that quantifies the impact of structural reforms on per capita income in OECD countries. It presents the overall macroeconomic impacts of reforms by aggregating over the effects on physical capital, employment and productivity...

We develop a general-equilibrium model to capture key features of the retailing and of the manufacturing industry in order to understand how these two industries interact and how labor is allocated between them. We show that the observed shift in employment from manufacturing to retailing, the...

This paper explores the relationships between the growth in the medical workforce in an aging society and employment in other sectors of the economy, based on data from the United States since 1985. Employment in medical services grew, but did not displace employment in other sectors uniformly....

Making use of restrictions imposed by equilibrium, theoretical progress has been made on the nonparametric and semiparametric estimation and identification of scalar additive hedonic models (Ekeland, Heckman, and Nesheim, 2002) and scalar nonadditive hedonic models (Heckman, Matzkin, and...

We develop an epidemic model to explain and predict the dynamics of the SARS-CoV-2 virus and to assess the economic costs of lockdown scenarios. The standard epidemic three-variable model, SIR (Susceptible, Infected and Removed) is extended into a five-variable model SCARE: Susceptible, Carrier,...

We review and interpret the main theoretical developments in the gravity literature from its very early, a-theoretical applications to the latest structural contributions. We also discuss challenges and implement methods to estimate empirical gravity equations. We finish with a presentation and...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...
