We estimate hedonic price functions for premium wine from Australia and New Zealand, differentiating implicit prices for sensory quality ratings, wine varieties and regional as well as winery brand reputations over the vintages 1992–2000. The results show regional reputations have become increasingly differentiated through time (although less so for New Zealand). In particular, cool‐climate regions are becoming increasingly preferred over other regions in Australia. In each country, price premia associated with both James Halliday's and Winestate magazine's sensory quality ratings, and with Halliday's winery ratings and classic wine designations, are highly significant.

Recent globalization has been characterized by a decline in the costs of cross-border trade in farm and other products. It has been driven primarily by the information and communication technology revolution and—in the case of farm products—by reductions in governmental distortions to agricultural production, consumption and trade. Both have boosted economic growth and reduced poverty globally, especially in Asia. The first but maybe not the second of these drivers will continue in coming decades. World food prices will depend also on whether (and if so by how much) farm productivity growth continues to outpace demand growth and to what extent diets in emerging economies move towards livestock and horticultural products at the expense of staples. Demand in turn will be driven not only by population and income growth, but also by crude oil prices if they remain at current historically high levels, since that will affect biofuel demand. Climate change mitigation policies and adaptation, water market developments and market access standards particularly for transgenic foods will add to future production, price and trade uncertainties.

This paper examines the extent to which various regions, and the world as a whole, could gain from multilateral trade reform over the next decade. The World Bank's Linkage model of the global economy is employed to examine the impact first of current trade barriers and agricultural subsidies, and then of possible outcomes from the WTO's Doha Round. The results suggest moving to free global merchandise trade would boost real incomes in sub-Saharan Africa and Southeast Asia (and in Cairns Group countries) proportionately more than in other developing countries or high-income countries. Real returns to farmland and unskilled labour, and real net farm incomes, would rise substantially in those developing-country regions, thereby helping to reduce poverty. A Doha partial liberalisation could take the world some way towards those desirable outcomes, but more so the more agricultural subsidies are disciplined and applied tariffs are cut, and the more not just high-income but also developing countries choose to engage in the process of reform.

Notwithstanding the tariffication component of the Uruguay Round Agreement on Agriculture, import tariffs on farm products continue to provide an incomplete indication of the extent to which agricultural producer and consumer incentives are distorted in national markets. As well, in developing countries especially, non-agricultural policies indirectly impact on agricultural and food markets. Empirical analysis aimed at monitoring distortions to agricultural incentives thus need to examine both agricultural and non-agricultural policy measures including import or export taxes, subsidies, and quantitative restrictions plus domestic taxes or subsidies on farm outputs or inputs and consumer subsidies for food staples. This paper addresses the practical methodological issues that need to be faced when attempting to undertake such a measurement task in developing countries. The approach is illustrated in two ways: by presenting estimates of nominal and relative rates of assistance to farmers in China for the period 1981–2005; and by summarizing estimates from an economy-wide CGE model of the effects on agricultural versus non-agricultural markets of the project's measured distortions globally as of 2004.
