Does the Home Market Effect Arise in a Three-Country Model?
It is uncertain whether the fundamental “home market effect” (HME) generalizes from a two-country model to a more realistic setting with multiple countries. We present a three-country version of the seminal model by Krugman (1980) and analyse under which circumstances the HME is present once third country effects are taken into account. We show that both expenditure shifts and exogenous enlargements among foreign countries can rule out the HME.
