We demonstrate that the Varian (1980) model of sales has a unique Nash equilibrium when firms incur costly advertising to compete for informed consumers. The equilibrium is symmetric. In particular, with costly advertising, the asymmetric equilibria highlighted by Baye et al. (1992) do not arise.

We show that, in general, consistent estimates of cost pass-through are not obtained from reduced-form regressions of price on cost. We derive a formal approximation for the bias that arises even under standard orthogonality conditions. We provide guidance on the conditions under which bias may...

We analyze the sourcing strategies of firms active in the Spanish manufacturing sector. We show that firms that select strategies of vertical integration and of foreign sourcing ex post tend to have been more productive, ex ante, than other firms.

This paper calculates a unit labor-cost based real effective exchange rate for China for the period 1987-2002. It examines carefully which data sources can be used given the known limitations of Chinese data and constructs to them together with internationally available unit labor cost...

We use the well known USDA dataset of real exchange rates to address the question of whether PPP holds for agricultural commodities. Both unit root tests and the recently proposed more powerful class of panel unit root tests, which take into account cross-section correlation across the units in...

As a prelude to tariff reduction, the government is currently assessing the implications of significantly reducing tariffs due, in part, to its 2001 agreement with Ghana to quickly implement the ECOWAS Trade Liberalization Scheme. The obvious questions are: Should Nigeria liberalize to all...

This paper aims to evaluate the trade potential of manufactured products between the members of the EU25 in the threshold of its Eastern enlargement. We estimate, for 2002, a cross-section gravity model, whose coefficients will be used to project the “natural” trade relations between them....

One of the most significant recent developments in world trade has been the entry of China into the World Trade Organization (WTO). This paper examines the implications of China’s WTO accession for India’s trade, using both econometrics and computable general equilibrium (CGE) models. The...

This paper estimates the potential effects of a free trade agreement (FTA) between China and Mercosur on poverty, income distribution, welfare and employment. The case of Argentina, in particular, is investigated. To this end, partial equilibrium techniques are combined with micro econometric...

The current slump in world coffee prices is mainly due to a structural oversupply. Instead of introducing price measures, measures aimed at reducing this excess supply would be a more efficient method of increasing coffee producers'incomes.
