TRANSCRIPT
Another new important development was a recommendation to govern- ments to establish transparent mechanisms at the national level to evaluate protectionism sought by firms and sectors. and their implica- tions for both the domestic economy and for developing countries. Fmally. endorsing the organization’s work programme on services. the Confer- ence requested UNCTAD to analyse the implications of issues and prob- lems raised in the context of trade in services.
AI far as particular problems of least-developed countries are con- cerned the Conference stressed. irlter alia. the need for their national efforts to enhance development, diversifica- tion and structural adjustment through mobilization of human and other resources. the provlslon of in- centlves and the strengthening of their planning capacity. At the internation- al level, the need for the full imple- mentation of the ‘Substantial new programme of action for the 1980s for least developed countries’ was reaf- firmed. Increases in grants and other financial flows (particularly on conces-
sionary terms). an expansion of tech- nical assistance and cancellation of official development assistance debts were also recommended. Mention was also made of the need to support the efforts of least-developed countries to increase food production.
To conclude, the Conference took few decisions which could be im- plemented immediately to remedy some of the world economic prob- lems. Nevertheless. It did appear to mark a shift in thinkmg and percep- tions about these problems. More- over, it agreed on a comprehensive framework wlthin which attempts should be made to resolve the inter- related problems of debt, commod- ities and the trading system for revita- lization of growth, development and internatlonal trade.

The importance of consumer beliefs
September-2 October 1987
This 7th Congress of Food Science and Technology, held in Singapore, was attended by over 1000 delegates’ and associates with over SO0 scientific con- tributions bemg presented at 50 sebs- ion\ during the four days of the meetmg.
Five of the seven speakers of the plenary lectures were concerned with human factors The economic milieu to be anticipated till AI> 2000 and the past (and future) development of functions of the International Union were considered by Dr Kmg and Professor Hawthorn. while Professor Bender discussed the growing interest in the interactions of diet and health. He warned of the dangers of acting on

Professor Linko described develop- ments in biotechnology. He instanced work in Finland where barley starch is used industrially to manufacture sugars (dextrose. glucose and maltose syrups, high fructose products and pure fructose) by enzyme techmques. He also outlined future possible ap- plications of biotechnology.
Maillard reactions
The Maillard reactions, by which different substance\ are formed. occur between protems and sugars m food. Some provide colour (of bread crusts and roasts) or aromas (of cooked food) while other5 give rise to ‘off flavours’ (of ctale products). Some
Maillard products are towlc, others
have beneficial actions. Professor Kate Hiromichl reviewed the research

Hormones
Certain synthetic substances with hor-
mon:il effects were once used in e~ces-
\ive amounts. Mr:lt from treated
imimals led to very serIou\ effects when incorporated into infant foods.
The uhe of these substances. which are quite different from any natural hor- mones of the body. w;~s rapidly prohl- bited. Many different hormones art’ formed In the body and are ub- quitously present m aII animal pro- ducts. These hormones arc now avail- :1bk and \ome Improve output of

Thirty years of invrstigatlon have failed to \how harmful effects from Irradiated foods though the proce\\ can eliminate pathogens and increa\r storage life. Several countries and the Co&x Alimentariu\ of the UN have
approved Irradiation. Many consumer organizations have \uch grave reserve- tlons that the procas may not be
commercially viable in 4omc‘ countries even if legally permissible. Several paper\ reported public mistrust of irradiation and the fact that thl\ prob- ;tbly depends on the strong a\\oclation

between the term ‘irradiated’ and the harmful effects of ‘radioactivity’. This relation has led many to beheve that trradtated food is radioactive and so could lead to harm.
Both of these processes could be beneficial were it not for mistaken beliefs. These two instances should warn manufacturers and innovators that even when all needs for safety, costs and convenience are met. suc- cess still depends on the beliefs of the consumer. If these are adverse the facts become Irrelevant. Who would serve sucking pig in blecca. or
horsemeat steaks at a pony club din- ner, no matter how nutritious or hygienic these products might be?

The mutual benefits of reducing agricultural assistance NATIONAL POLICIES AND
AGRICULTURAL TRADE
OECD, Paris, France, 1987, 333 ppg FF 2500 hb, FF 120 pb
Fourteen years ago when Professor Timothy Josling outlined the method- ology for calculating assistance to agri- culture which IS central to Nrrr~~r~rrl Poli&s rml Agm’ultwrrl Trrrtle. it
would have been unthinkable that all the OECD governments would have agreed to the publication of this book under the OECD imprint. with a title which directly linked national agrt- cultural policies and agricultural trade
Even five years ago, when the OECD mmisterial meeting provided the mandate to ‘Analyse the approaches and methods for ;I bal- anced and gradual reduction of pro- tection for agriculture, and the fuller integration of agriculture within the open multtlateral trading system .‘, the mandate was still hedged with qualifications about the ‘specificity’ of agriculture and the need for ‘compata- bihty between agricultural policies and ‘orderly’ trade.
This book is therefore a very signifi- cant publicatton, since it constitutes
the first offtctal recognition by all OECD governments ~ albett implicitly by their tactt acceptance of the text - that domestic agricultural policies are the direct cause of the agrtcultural trade problem.
The agricultural trade problem IS
well known and is documented throughout the book. Global produc- tton of most major bulk agricultural commodities has risen to the point where the surpluses avanable for in- ternational trade grossly exceed the international market’s capacity to absorb them, even at prices which are heavily subsidized, or all but inadequ-
ate to provide reasonable returns to
the most efficient exporters.
Footing the hill
The root cause of this imbalance lies in the domestic policies of most of the developed - and Increasingly of the developmg - countries where. in an attempt to achieve various strategic, socud and environmental objectives, subsidies are paid to producers. or prices for agricultural produce are set at higher levels than would be neces- sary tf only economtc considerattons were taken into account. As a result producers respond to the distorted
price signals by increasing production. and consumers by decreasing or hold- ing static consumptton. The taxpayer and/or consumer foots the bill.
The resulting imbalance bctwecn consumption and production is cx- ported. typically with a subsidy, to disrupt such tntrrnattonal markets as
do exist, or is stored at htgh cost and wtth the threat of future market dts- ruption.
The Increases in production are made possible by ;I vast reservoir of agricultural technology whose effects, in my opinion, may defeat attempts to reduce production for many more years than this book appears to anti- cipate.
The heart of the book, in which the agricultural trade problem 1s quantt- fied and analysed, IS an I l-country, 14commodtty model of agrtcultural production. demand and trade In this model a complex system of supply and demand elasticities are used to de- scribe demand, supply and effective
prices to producer and consumer for the various commodittes tn each coun- try. Countries are linked through trade: again. elasticity esttmates pro- vide the method by which consumers and producers can respond to changes in world prices. Changes in world
prices are assumed to be passed back
fully to consumers and producers.
The key policy concept which I\
used to trigger changes in world prices
and to link domestic agricultural poli-
cies and agricultural trade is the PSE -
the Producer Subsidy Equivalent. A
less important concept 1s the CSE. or
Consumer Subsidy Equivalent. The CSE is also quantified and discussed In
the text.
Essentially the PSE is a summation
of: (I) direct and imphctt budgetary
payments to producers in the indt-
vidual countries (eg income transfers, input subsidies, tax rebates, subst- dized R&D, etc): and (2) market price
support to producers m the various
countries.’ The PSE is. therefore. ;I
comprehenstve estimate of the level of
assistance to producers in the various
countries which can be expressed
either as an aggregate monetary sum,
or per unit of production, or as ;I
percentage of producer values.
The CSE, the other measure of
