Genetically modified plants and the precautionary principle

The European regulation of genetically modified plants is a particular example of technological risk management that has become an essential part of the management of change. The role of regulators in this management process, when there are demands for regulatory action concerning unquantified (and sometimes unquantifiable) technological risks – with regulation under conditions of uncertainty – is explored. Where the retrospective evidence concerning a postulated risk scenario is sparse, the precautionary principle (PP) may be invoked. The origins of the European regulatory system, which applied until 17 October 2002 (Directive 90/220), why this has been revised (Directive 2001/18) and the probable impact of this revision are described. This is illustrated with risk assessments that have accompanied submissions for marketing approval for genetically modified plants under Directive 90/220. Some of the problems associated with the PP and the regulation of GM plants are discussed.     

Five charges against the precautionary principle

We defend the precautionary principle against five common charges, namely that it is ill-defined, absolutist, and a value judgement, increases risk-taking, and marginalizes science. We argue, first, that the precautionary principle is, in principle, no more vague or ill-defined than other decision principles and like them it can be made precise through elaboration and practice. Second, the precautionary principle need not be absolutist in the way that has been claimed. A way to avoid this is through combining the precautionary principle with a specification of the degree of scientific evidence required to trigger precaution, and/or with some version of the de minimis rule. Third, the precautionary principle does not lead to increased risk-taking, unless the framing is too narrow, and then the same problem applies to other decision rules as well. Fourth, the precautionary principle is indeed value-based, but only to the same extent as other decision rules. Fifth and last, the precautionary principle is not unscientific other than in the weak sense of not being exclusively based on science. In that sense all decision rules are unscientific.     

The precautionary principle: an 'unprincipled' approach to biotechnology regulation

A tenet of administrative law, particularly in the United States, is that regulators must base their decisions on 'intelligible principles' to provide consistency, predictability, transparency and accountability. The precautionary principle, which purports to provide a new decision rule for making environmental decisions under conditions of uncertainty, fails to provide such an intelligible principle for making decisions. The precautionary principle is ambiguous on the use of the two major criteria currently used to make environmental decisions - significant risk and cost-benefit balancing - yet offers no new specific decision criteria in their place. The second fundamental problem with the precautionary principle is that it is based on the unsubstantiated premise that the current regulatory system is insufficiently protective. The current system already tends to err on the side of the safety, as it should, but the relevant question is just how precautious should we be? As illustrated by the example of genetically modified organisms, the prudent level of precaution depends on factors such as the magnitude, distribution and uncertainty of risks, the extent of exposure, and the trade-offs and lost benefits in foregoing the risk. These are precisely the factors that are considered under the current risk-based approach, which the precautionary principle seeks to replace.     

A precautionary tale:

In the wake of the minimal disruption to computer systems arising from the Y2K Millennium Bug, there has been a notable lack of discussion about whether the huge expenditures devoted to solving the problem were justified. The most common response was that they were worth it ‘just to be on the safe side’. Furthermore, there were many related benefits in upgraded infrastructure and improved systems. We argue that in fact Y2K activity is an important if unexpected example of the ‘precautionary principle’ at work, i.e. acting in advance to ward off potential danger despite a lack of full scientific certainty about the extent of danger. It was unexpected because it was championed by corporations and governments who routinely oppose precautionary policies directed at environmental issues such as global warming. The paper outlines several reasons why Y2K was acted upon so swiftly while environmental issues are not, and explores what lessons may be learnt from the Y2K episode in terms of future strategies for dealing with environmental danger.     

The influence of the precautionary principle on science-based decision-making: questionable applications to risks of radiofrequency fields

The precautionary principle, recognized by the European Commission as a 'full-fledged and general principle of international law,' has been advanced as a paradigm for response to potential risks to the environment or health when scientific data are uncertain. But lacking the elements and operational qualities that characterize principles that have proven useful in law, politics, science, and ethics, the precautionary principle lends itself to regulation based on the perception of a threat or fear itself. In the absence of scientific evidence for risk, recent application of the precautionary principle to questions about radiofrequency electromagnetic fields of cellular telephones and cellular telephone base stations has produced wasteful and misguided regulations and questionable advice to the public. The formation of scientific 'fire brigades' is suggested for rapid acquisition of targeted scientific data needed so that precautionary policies on technologically driven issues can be based on quantitative risk assessment.     

The precautionary demand for money: A rigorous foundation

Consumers' demand for money to hold is shown rigorously to be related to possible but uncertain purchase opportunities rather than to total consumption (income) or to the variability of bond yields. A formal model of consumers' demand for precautionary balances is analyzed. It implies that cash balances demanded will be changed by different amounts in response to equivalent changes in the rates of time preference and inflation. This perhaps explains recent instability in money demand estimates.

Buffer stocks and precautionary savings with loss aversion

This paper reexamines buffer stocks and precautionary savings in the presence of loss aversion. We assume that agents are disappointment averse, as in Gul [Econometrica, 59 (1991) 667–686]. We show that the concavity of the marginal utility continues to determine precautionary saving, but its effect is of a second order magnitude (proportional to the square of the coefficient of variation) compared to the first order effect (proportional to the coefficient of variation) induced by loss aversion. We show that a stabilization fund that is rather small when agents are maximizing the conventional expected utility, turns out to be rather large with loss aversion.     

The ageing of Europe: Demographic scenarios of Europe's futures

This paper explores the demographic futures of Europe by presenting two scenarios. The ‘silver century’ scenario is based on the continuation of current demographic trends and policies. In this scenario, Europe's population will continue to age and immigration will be limited. As a result younger people will increasingly tend to concentrate in urban areas while the retirees, who are able, will settle in suburban and rural spaces. In the ‘open borders’ scenario, the EU and most of the member states will introduce an open and actively promoted immigration policy. Most immigrants will concentrate in large metropolitan areas. At the same time there will also be some countries and regions with very limited immigration from abroad. At the local scale immigration will contribute to social and spatial segregation. Hence, without the regulation or at least management of types and destinations of immigration, demographic imbalances will not be addressed at the regional level. Furthermore while the freedom of movement may have some macro-economic benefits and address population imbalances in some (mainly metropolitan) areas, pre-existent trends undermining both socio-economic cohesion and sustainable patterns of development are unlikely to be resolved.     

Comparative precautionary saving under higher-order risk and recursive utility

Measuring and comparing the precautionary saving motive rest almost exclusively on the expected utility framework, and only focus on income risk or coefficients of the Arrow–Pratt type. We generalize the standard approach by characterizing comparative precautionary saving under recursive utility for increases in income risk and increases in risk on the saving return, including higher-order risk effects. We express the comparisons in terms of precautionary premia. In addition, we define a new class of preference coefficients, and derive the associated conditions to predict a stronger precautionary motive. The coefficients provide a detailed picture of the preferences sustaining precautionary saving and could be useful in applications.     

Convertibility risk: the precautionary demand for foreign currency in a crisis

This paper presents theoretical work linking money demand to the perceptions of households about the risk that domestic currency may become inconvertible or that it may be devalued. An empirical investigation of the size of this effect is carried out using monthly data for Korea to estimate an augmented demand-for-money equation. It is found that the fear of inconvertibility arising from the 1997 Korean currency crisis may have caused broad money demand to fall by 4–5% points,equivalent to the loss of reserves of $6–7.5 billion (or about 30% of reserves as measured at end-November 1997). This is a revised version of IMF Working paper WP/2001/210; it was written while Professor Black was Senior Policy Advisor at the IMF Institute and Christofides and Mourmouras were staff members in the IMF’s Policy Development and Review Department. The views expressed are those of the authors and should not be attributed to the IMF, its Executive Board, or its management. For useful comments and suggestions we thank an anonymous referee, Tim Lane, Ydahlia Metzgen, Roberto Perelli, Tony Richards, Christian Mulder, Steve Russell, as well as seminar participants at the IMF Institute, the IMF’s Asia and Pacific Department, Federal Reserve Board, and Bank of Indonesia. We would also like to note similar (unpublished) empirical results using our approach by Dr. Rino Effendi for Indonesia and Angana Banerji for Russia     

Failed technology futures: pitfalls and lessons from a historical survey

Images of the future, with hindsight, turn out to be either right or wrong. In this article, past images of the impact of Information and Communication Technology (ICT) on traffic and transportation are investigated. Informed by the field of technology studies, seven key features are formulated that point at pitfalls and neglected aspects in many future expectations on technological developments and their societal impact. It is also argued that the evolution from broad sweeping promises to more down-to-earth assessments is inherent in technological developments, because expectations and diffuse scenarios also play a performative role in technological developments.     

Borrowing constraints,the cost of precautionary saving and unemployment insurance

When it is costly for individuals to save or to borrow, unemployment insurance (UI) provides an alternative source of liquidity that smooths consumption over time and leads individuals to spend longer unemployed searching for a suitable job. We show in a tractable life-cycle model how the optimal unemployment replacement ratio and the fall in consumption on job loss depend on the cost of self-insurance and the cost of borrowing. This implies that the value of UI depends on age at job loss, consumption needs (such as the presence of children), discount rates, the return on saving, access to credit and the presence of other social insurance programmes. Optimal replacement rates vary substantially with plausible variation in these factors (from less than 20 percent to almost 60 percent).     

Precautionary principle and discursive strategies: classifying and managing risks

The paper covers an integral risk concept consisting of a criteria-based risk evaluation, a novel proposal for risk classification and corresponding risk management strategies aimed at an analytic-deliberative approach in risk regulation. For this purpose, technical and scientific as well as social scientific concepts were integrated into a single conceptual framework. Eight criteria were selected for evaluating risks: probability of occurrence, extent of damage, incertitude, ubiquity, persistency, reversibility, delay effect and potential of mobilization. With respect to these criteria, six risk classes were formed in which risks may exceed thresholds determined by deliberative action. Effective and practicable management strategies were deduced for each risk class. The characterization and classification of risks provide a knowledge base for designing risk policies and class-specific management strategies. Three major management categories were identified: risk-based, precautionary and discursive strategies. In deliberative processes actors need to agree on norms and procedures to manage risks. If the results reflect the agreement of previous discourse procedures, political decisions become more legitimate. Because the risk evaluation, risk classification and management strategies are based on the concept of analytic-deliberative processes, the essential requirements for an effective and democratic risk policy are met.     

The geometric-mean principle revisited : A reply

As far as I know neither Samuelson nor Merton nor indeed Ophir has challenged the basic principle imbedded in the geometric-mean principle for long-run portfolio selection. If they or he wishes to adopt a significantly different policy and I follow the G policy, in the long run I become3almost certain to have more wealth than they. This hardly seems an erroneous or trivial proposition.     

Silo busting: how to execute on the promise of customer focus

For many senior executives, shifting from selling products to selling solutions--packages of products and services--is a priority in today's increasingly commoditized markets. Companies, however, aren't always structured to make that shift. Knowledge and expertise often reside in silos, and many companies have trouble harnessing their resources across those boundaries in a way that customers value and are willing to pay for. Some companies--like GE Healthcare, Best Buy, and commercial real estate provider Jones Lang LaSalle (JLL)--have restructured themselves around customer needs to deliver true solutions. They did so by engaging in four sets of activities: COORDINATION: To deliver customer-focused solutions, three things must occur easily across boundaries: information sharing, division of labor, and decision making. Sometimes this involves replacing traditional silos with customer-focused ones, but more often it entails transcending existing boundaries. JLL has experimented with both approaches. COOPERATION: Customer-centric companies, such as Cisco Systems, develop metrics for customer satisfaction and incentives that reward customer-focused cooperation. Most also shake up the power structure so that people who are closest to customers have the authority to act on their behalf. CAPABILITY: Delivering customer-focused solutions requires some employees to be generalists instead of specialists. They need experience with more than one product or service, a deep knowledge of customer needs, and the ability to traverse internal boundaries. CONNECTION: By combining their offerings with those of a partner, companies can cut costs even as they create higher-value solutions, as Starbucks has found through its diverse partnerships. To stand out in a commoditized market, companies must understand what customers value. Ultimately, some customers may be better off purchasing products and services piecemeal.
