The relative efficiency of ad-valorem and specific tariffs is still an active debate in the international trade literature. Contrary to the general belief about the ad-valorem tariff being superior under various imperfectly competitive market settings, it is shown that the specific tariff...

We modify Paul Krugman’s (1991) ‘Core–Periphery’ model by replacing the traditional competitive sector with a monopolistically competitive one. We show that the structure of spatial equilibria remains the same as in the original model. This result continues to hold true under Cournot or...

We examine the impact of (and links between) two types of economic integration on the stability of multimarket collusion when firms interact in quantities in segmented markets: (1) multilateral trade liberalization, captured by a reduction of trade costs across all markets; and (2) preferential...

Previous studies have shown that, not only countries, but also regions have a preference to trade within their administrative borders. Using unique trade flows data, we also find a large home bias in Spanish intranational trade. However, we show that this home bias tends to disappear once we...

We study the variation in ownership shares across affiliates of the same multinational firm. Using the micro-level data on foreign affiliates of South Korean multinationals, we construct a proxy for the headquarter intangible asset using transferred Korean workers from the parent to the...

In this paper we present new evidence on the aggregate effect of the euro on trade using data for 26 OECD countries for the period 1967–2008. We strive to fill the gaps present in the previous literature through a second-generation panel cointegration tests and estimators that account for both...

In an economy with voluntarily provided public goods and private product varieties, and a general class of CES preferences, it is shown that aggregate public good contribution follows an inverted-U pattern with respect to group size when private and public goods are substitutable in preferences....

Presenting a novel model of local shopping, the benefit of monopoly provision due to market size effects is explored. Prices are lower, variety and aggregate consumer surplus higher, than local shopping but many shoppers’ utility falls. Policymakers should take care.

We develop a model of monopolistic competition that accounts for consumers’ heterogeneity in both incomes and preferences. This model makes it possible to study the implications of income redistribution on the toughness of competition. We show how the market outcome depends on the joint...

Two counter-intuitive results regarding the number of firms emerge from the existing monopolistic competition literature. First, the number of firms is positively related to the extent of the monopoly power. Second, when the goods market is perfectly competitive, the number of firms is reduced...
