Abstract

Studying the standard monopolistic competition model with unspecified utility/cost functions, we find necessary and sufficient conditions on the function elasticities, when an expanding market or trade incur welfare losses. Two numerical examples explain why: either excessive or insufficient entry of firms is aggravated by market growth. The variable marginal cost enforces the harmful effect. Still harm looks practically improbable.
