(e) Price volatility

Speaking of risk, we have seen that price volatility of food crops in Africa is the highest in the world.

Security problems and disruptions in production also increased price volatility.

CAMBRIDGE Under French President Nicolas Sarkozy s leadership, the G 20 has made addressing food price volatility a top priority this year, with member states agriculture ministers meeting recently in Paris to come up with solutions. Small wonder world food prices reached a record high earlier in the year, recalling a similar price spike in 2008.

Producing countries have also tried to contain price volatility by forming international cartels. But these have seldom worked.

Recent global economic trends called for major policy initiatives, for example for export diversification, investment in infrastructure and control of price volatility.

Now, the price of food, many people complain about, but in fact, the price of food is going down, and that's odd because in fact, consumers are not paying for the true cost of food.

UNCTAD is also actively working on issues related to the impact of oil price volatility on African oil importing and oil exporting countries.

In particular, the volatility of food and commodity prices, including petroleum prices, is seriously denting the financing capacity of many poor countries.

Long distance telephone service sold on price, price, price fast food restaurants with all their value pricing and even the Internet is commoditizing not just goods, but services as well.

Protectionism threatens open markets and GDP growth. And price volatility, whether triggered by drought or short sighted national policies, could deter investments in agriculture and decrease the poor s purchasing power.

LONDON In the 1960 s, the Green Revolution which included the development of high yielding crop varieties, the expansion of irrigation infrastructure, and the distribution of modern fertilizers and pesticides to developing country farmers bolstered agricultural production worldwide. But chronic hunger remains pervasive, particularly in developing countries, which are affected most by crop shortages and food price volatility.

Faced with the erratic nature of agricultural markets, regulation is needed to soften the impact on poorer countries of volatile food prices. This does not mean that protectionism is the way forward, only that taking account of specific issues that affect international farm trade weather, price volatility, or health risks may be necessary from time to time.

Where Did Market Volatility Go?

It was important for the international community to take action to improve their access to trade financing, protect them against the adverse effects of trade liberalization and commodity price volatility, and reduce their transport costs.

Export restrictions in producing countries and price controls in importing countries both serve to exacerbate the magnitude of the world price upswing, owing to the artificially reduced quantity that is still internationally traded. If producing and consuming countries in grain markets could cooperatively agree to refrain from such government intervention probably by working through the World Trade Organization world price volatility might be lower.

Lowering volatility and sopping up excess liquidity can be beneficial, but there are risks here as well regulators can easily overshoot the mark, leaving financial markets with weakened capacity for price discovery and too little liquidity.

They held large inventories of these assets, thus providing liquidity and smoothing excess price volatility. But, with new regulations punishing such trading (via higher capital charges), banks and other financial institutions have reduced their market making activity.

Global economic instability correlates strongly with energy price volatility. Economic development is in significant part defined by the process of overcoming energy poverty, yet 1.6 billion people still lack access to even the most basic energy services.

Fredrick the Great of Prussia was very, very keen for the Germans to adopt the potato and to eat it, because he realized that if you had two sources of carbohydrate, wheat and potatoes, you get less price volatility in bread.

In the United States, the financial sector is undergoing a high speed but permanent structural transformation, the effects of which could be severe for developing countries economic growth. Indeed, these countries are already experiencing large relative price increases for food and oil, a food emergency for the poor, and higher rates of inflation induced by commodity price shifts.

If we allow food to be used to produce bio fuels, food prices will be linked to the oil price, as the head of the German farmers association happily announced. Indeed, food prices are currently increasing in Europe, because more and more farmland is being used for bio fuels instead of for food production.

Higher food and energy prices put upward pressure on price levels in the subregion, which was partially offset by fuel subsidies in some countries.

Moreover, energy and food price shocks can be both large and largely unpredictable, while the speed of price changes tends to increase with big shocks. Most forecasting models used by central banks therefore put a large weight on recent inflation.

Fortunately, there is little reason to believe such dire predictions, or that the market gyrations that have been driving recent headlines represent anything more than short term volatility. After all, equity price movements are a poor predictor of the real economy s performance.

The era of floating exchange rates that followed the end of the gold standard required the development of products that could protect international trade from price volatility. This opened the way to options, selling and buying on credit, and derivatives of all kinds.

True, market forces have spurred innovation, which has continually driven down the price of processed food, even as the price of plain old fruits and vegetables has gone up. That is a fair point, but it overlooks the huge market failure here.

Whatever your reason for wanting to do this, whether you're concerned about national security or price volatility or jobs, or the planet, or your grand kids, it seems to me that this is an oil endgame that we should all be playing to win.

WEST LAFAYETTE, INDIANA Food prices have in many cases surpassed the peak levels reached in July 2008. At that time, food price increases were attributed to growing global demand for food commodities, a major decline in the value of the US dollar, crop failures in some parts of the world, and biofuels.

In some areas of Burkina Faso, Chad, Mali, Mauritania, Niger and Senegal, the price of food especially millet doubled, while prices for undernourished cattle and other livestock plummeted.

Economists have identified six pitfalls that can afflict natural resource exporters commodity price volatility, crowding out of manufacturing, Dutch disease (a booming export industry causes rapid currency appreciation, which undermines other exporters competitiveness), inhibited institutional development, civil war, and excessively rapid resource depletion (with insufficient saving).

My work provides a new and coherent approach to macroeconomics that explains how a lack of confidence can lead to persistent unemployment. It supports the purchase of equities by central banks to reduce asset price volatility, restore the value of wealth, and prevent a future market crash.

They just care about three things and three things only price, price and price.

TOKYO In the last week or so, stock markets around the world have been hit by an upsurge in volatility, with large price swings confronting traders in New York, Tokyo, London, and beyond. And the entire global financial spasm has been largely blamed on a single culprit China.

But, over time, the longer central banks create liquidity to suppress short run volatility, the more they will feed price bubbles in equity, bond, and other asset markets. As more investors pile into overvalued, increasingly illiquid assets such as bonds the risk of a long term crash increases.

At the same time, it would buffer consumers from oil price volatility, thereby stabilizing their energy spending. Finally, and perhaps most important, such an approach would be more politically attractive than a fixed carbon tax, especially if it is introduced at a time of sharply declining oil prices.

Everything changed in 1971, when US President Richard Nixon, unable to contain the fiscal deficit resulting from spending on the Vietnam War and expanded social welfare programs, abolished the dollar s direct convertibility to gold. The resulting exchange rate, interest rate, and commodity price volatility continues to this day.

They should also mitigate the impact of the excessive volatility of financial markets.

The aim should be to avoid volatility and to ensure stability and fairness.

The G 20 s efforts will culminate in the Cannes Summit in November. But, when it comes to specific policies, caution will be very much in order, for there is a long history of measures aimed at reducing commodity price volatility that have ended up doing more harm than good.

(iv) Initiate measures that mitigate the impact of excessive volatility of short term capital flows.

And, finally, sharp movements in interest rates and exchange rates can cause volatility in other markets, most notably for equities. Because regulatory controls and market constraints have made brokers less able to play a countercyclical role by accumulating inventory on their balance sheets, the resulting price instability is likely to be large.

PRICE

Likewise, following the 2008 global economic crisis, food price spikes and recession caused the United Nations Food and Agriculture Organization to revise its hunger estimates upward, to more than one billion people. Considering the FAO s conservative definition of chronic severe hunger, this is a serious indictment of global poverty reduction efforts.
