Science has been among the beneficiaries of the digital revolution, spawning yet other revolutions, such as in biotechnology and nanotechnology. Foreign direct investment FDI liberalization sometimes has been a complement to trade liberalization. Developing countries so far are only minor players as hosts of FDI in processed food, beverages and tobacco, however: In most HICs now, no more than five firms account for the majority of sales, and in many of those countries, the four top firms have more than two-thirds of sales.
Supermarkets have been spreading even faster in developing countries than they did in HICs. This is having dramatic effects further up the value chain. First-stage processors, food and beverage manufacturers, and distributors are also becoming more concentrated so as to better match the bargaining power of supermarkets, although typically in narrowly focused industries rather than across the board as in supermarket retailing. Their actions are constrained too by the supermarkets' capacity to develop their own brands and even their own processing and distribution.
In addition to agricultural trade being affected by economic growth and declining trade costs, it has been greatly affected by distortionary government policies.
Since the s, world agriculture has been characterized by the persistence of high agricultural protection in developed countries, by anti-agricultural and anti-trade policies of developing countries and by the tendency for both sets of countries to use trade measures to stabilize their domestic food market—thereby exacerbating price fluctuations in the international marketplace. This disarray has not only been highly inefficient but has also contributed to global inequality and poverty since the vast majority of the world's poorest households depend directly or indirectly on farming for their livelihoods; see Anderson et al.
The situation worsened up to the mids, with agricultural protection in Europe, North America and Japan peaking and international food prices plummeting in , thanks in large measure to an agricultural export subsidy war between the US and the European community.
Meanwhile, many developing countries had been reducing farm incomes not only by heavily taxing agricultural exports but also, albeit indirectly, by protecting manufacturers from import competition and overvaluing the national currency. This disarray in world agriculture meant that there was over-production of farm products in HICs and under-production in more-needy developing countries. Author's compilation using data from Pfaffenzeller et al. Solid line, real food price index.
During the past quarter-century, numerous developing countries and HICs have begun to reform their agricultural price and trade policies. This has contributed to the rise in the extent to which farm products are traded internationally, noted above. Much of this reform was undertaken unilaterally or as part of regional trading arrangements, but some was also undertaken in response to international pressures such as Uruguay Round stipulations, commitments required for accession to the World Trade Organization WTO and structural adjustment loan conditionality by international financial institutions.
A recent World Bank research project see Anderson and www. Its most basic measure, the nominal rate of assistance NRA is the percentage by which government policies have raised gross returns to farmers above what they would be without the government's intervention or lowered them, if the NRA is negative. Farmers are affected not just by prices of their own outputs but also albeit indirectly through changes to factor market prices and the exchange rate by the incentives offered to non-agricultural producers.
That is, it is relative prices and hence relative rates of government assistance that affect producers' incentives, so a relative rate of assistance RRA was also calculated. Nominal rates of assistance to agriculture in HICs and European transition economies and in developing countries, — per cent, weighted averages. The average NRA for developing countries conceals the fact that the exporting and import-competing subsectors of agriculture have very different NRAs. The anti-trade bias within agriculture the taxing of both exports and imports has diminished for developing countries since the mids, but the NRA gap between the import-competing and export subsectors still averages around 20 percentage points and it has grown to 40 percentage points for HICs, although there even exporters have enjoyed positive NRAs.
Nominal rates of assistance to exportable, import-competing and all covered agricultural products covered products only, and the total also includes non-tradables , HICs and developing countries, — Black lines, import competing; grey lines, exportables; dashed lines, total. The improvement in farmers' incentives in developing countries is understated by the above NRA estimates, because those countries have also reduced their assistance to producers of non-agricultural tradable goods, most notably via cuts in restrictions on imports of manufactures.

For the period since the mids, changes in the NRAs of both sectors have contributed almost equally to the improvement in incentives to farmers. This increase from a coefficient of 0. This is mostly because of the changes in Asia, but even for Latin America this relative price hike is one-half, while for Africa this indicator improves by only one-eighth.

The exceptions are Australia and New Zealand, where manufacturing protection had been very high and its decline occurred several decades later than in other HICs Anderson et al. Nominal rates of assistance to agricultural and non-agricultural sectors and relative rate of assistance, developing countries and HICs, — per cent, production-weighted averages across countries. The above influences of policies focus on long-term trends, but policies also influence year-to-year fluctuations around trend prices and quantities as governments seek to reduce fluctuations in domestic food markets.
One way for a country to achieve that objective is by varying the restrictions on its international trade in food according to seasonal conditions domestically and changes in prices internationally.

The unweighted average estimate for the short-term elasticity for 12 key products is 0. To assess how far the world had come, and how far it still has to go, in rectifying the disarray in world agriculture, Valenzuela et al. It quantifies the impacts both of past reforms and current policies by comparing the effects of the recent World Bank project's distortion estimates for the period — with those of The findings from that economy-wide modelling study suggest that:.
With this as background, we are now able to consider the likely drivers of changes in national agricultural comparative advantages, trade costs and pertinent policies over the next four decades and their associated uncertainties and impacts on global farm trade.

The list includes the following, each of which is considered in turn in the rest of this section of the paper:. The economic recession in the USA and Europe since has slowed global economic growth. In that process of readjustment, while long-term growth rates to may not be greatly affected, currencies may be realigned in ways that have long-term effects on comparative advantages in farm products. However, there is too much uncertainty surrounding such possibilities at this stage to do more than simply note them. Clearly, these projections imply significant changes to the economic centres of gravity of consumption in the global economy, given differing income elasticities of demand for various products.

They also affect the supply side of each economy: Global population and GDP per capita by region, actual and projected In economy-wide computable general equilibrium model projections, it is common to represent physical capital assets and human skills explicitly, but to incorporate new technologies simply as shocks to total factor productivity TFP; the number of units of each input needed to produce a unit of output.
The latter can be determined endogenously if the modeller accepts projections of growth in per capita income and in the various factors of production, but it is then a challenge to allocate that aggregate TFP shock to different sectors and to different industries within those sectors. With the growth in international food prices over the — period, however, expectations about their future trend are now less certain.
The possibilities of technological catch-up by lagging regions through faster international technology transfer also need to be considered e. This suggests that more than one set of assumptions about productivity growth is needed in developing a family of baselines for projections of agricultural productivity to Also of more relevance to projections now than in the past are assumptions about food consumption growth. Previously, modellers have relied on past econometric evidence, suggesting that price and income elasticities of demand for food decline with per capita income, and earlier for lower-valued foods such as staple grains and tubers than for livestock and horticultural products.
The latter switch will be especially important with the rapid income growth in populous emerging economies such as Brazil, China and India. However, consumer concerns for food quality, food safety and the environment also need to be considered, especially for HICs. Increasing numbers of consumers wish to know how products are produced on-farm and processed, so as to assess whether they are causing environmental damage or reducing animal welfare. The continuing preference of some consumers to avoid foods containing genetically modified organisms GMOs is a clear case in point Qaim This consumer concern has already led to significant government barriers to trade based on production processes and to constraints on domestic production.
If that behaviour persists, models of international trade need to differentiate between products that may or do not contain GMOs.

Now that traceability information along with other attributes can be stored on barcodes, these and related biosecurity concerns can be reflected in the demands that the large supermarket chains place on their suppliers for information on myriad attributes of products. This is adding to the need to incorporate greater agricultural product differentiation across suppliers in trade models.
It could be argued that the above concerns of consumers are confined to HICs, especially Western Europe and Japan, where the quantity of food consumed is unlikely to grow rapidly over the next four decades because of relatively low population and income growth and low-income elasticities of demand for farm products there.
However, that would be to miss the point that high-income consumers are willing to pay substantial premia for foods that are perceived to be safer, of higher quality and produced with minimal damage to the environment and animal welfare. They are thus potentially highly profitable markets to which all farmers seek access, including those in developing countries—notwithstanding the disadvantage due to their higher carbon footprint insofar as more transportation is probably required to get their produce to those northern markets than is the case for local import-competing farmers.
While the real price of crude oil spiked briefly in mid at nearly three times its previous record, it provides no guidance as to the long-term trend price of petroleum and other energy raw materials. Spikes in the spot price can occur whenever there is a sudden change in expectations including about OPEC cartel actions , given the low short-term price elasticities of demand and supply for crude oil. Long-term trend prices, on the other hand, are affected by government taxes and developments in known reserves and in demand, which tend to change relatively slowly as economies grow.
Technological innovations in exploration and exploitation have caused reserves to expand faster than demand, so the world is apparently not running out of fossil fuels: The capacity of petroleum prices to spike occasionally is not unlike that for grains. As Wright pointed out, wheat, rice and maize are highly substitutable in the global market for calories, and when aggregate stocks decline to minimal feasible levels for trading and processing, prices become highly sensitive to small shocks. When there were then some crop failures plus a surge in demand because of biofuel mandates and subsidies, grain prices started rising.
The crude oil price spike in raised further the demand for biofuels as well as fuel and fertilizer input costs for farmers , and a sequence of trade restrictions by key grain exporters, beginning in the thin global rice market in the autumn of , led to panic buying. The linkage between crude oil and food prices will remain strong when petroleum prices exceed the threshold that makes biofuel production privately profitable on a significant scale, as in — FAO ; IMF ; DEFRA ; Pfuderer et al.
A continuation of biofuel subsidies and mandates will make this co-movement in above-trend prices more common, as will the development of new biofuel crop production technologies that effectively lower the threshold oil price above which ethanol or biodiesel production is profitable Chakravorty et al. Mandates to include an increasing proportion of biofuels in road transport fuel are now in place in most OECD countries and in Brazil.
The current targets in the EU mandate go through to , and those of the US to These policy measures, if they continue and remain inflexible, will add a certain demand for biofuel crops no matter what happens to fossil fuel and food prices. This will not reduce the extent of any downward food price spike, however, because biofuel production will be privately profitable and so the mandates will tend to be redundant when grain and oilseed prices are very low relative to fossil fuels prices.
