Abstract

We revisit the Heckscher‐Ohlin‐Samuelson model in the presence of labour market frictions à la Mortensen‐Pissarides. Relaxing the assumption of the one‐worker‐one‐firm matching rule, we show that the Stolper‐Samuelson theorem and the Rybczynski theorem may not hold in specific circumstances. We also demonstrate that the Factor Price Equalization theorem is valid only for capital and unemployed labour across countries, but not for employed labour. In equilibrium, trade patterns are determined by countries’ factor endowments and relative factor intensities in sectors (independent of factor intensities in production). Finally, our results suggest an additional explanation for the ‘missing trade’ phenomenon. On ré‐examine le modèle de Heckscher‐Ohlin‐Samuelson quand il y a des frictions à la Mortensen‐Pissarides sur le marché du travail. En relaxant la règle d’appariement un‐travailleur‐une‐entreprise, on montre que le théorème de Stolper‐Samuelson et celui de Rybczybski peuvent ne pas être valides dans certaines circonstances spécifiques. On montre aussi que le théorème d’égalisation du prix des facteurs est valide seulement pour le capital et le travail non employé entre pays, mais non pour le travail employé. En équilibre, les patterns de commerce sont déterminés par la dotation en facteurs de production des pays et les intensités relatives d’utilisation des facteurs de production entre secteurs (sans rapport avec les intensités de facteurs dans la production). Finalement, les résultats suggèrent une explication additionnelle du phénomène du ‘commerce manquant.’
