IMPACTS OF TAXES TO REDUCE AGRICHEMICAL USE WHEN FARM POLICY IS ENDOGENOUS

The economic impacts of policies to reduce water pollution from agriculture have been explored in a number of studies. A standard assumption in this literature is that farm income support policies are given. However, the modern public choice view of agricultural policy suggests that significant environmental initiatives in agriculture would likely be accompanied by changes in farm income policies to protect those with a significant stake in agriculture. We explore the potential effects of such compensating adjustments on the costs and effectiveness of taxes on polluting chemical inputs in US corn production. We find that compensating farm policy adjustments can greatly increase the costs and reduce the effectiveness of the environmental protection measure. The results also indicate the potentially high costs of poor policy co-ordination.     

Doing more harm than good? Community based natural resource management and the neglect of local institutions in policy development

Approaches to natural resource management emphasise the importance of involving local people and institutions in order to build capacity, limit costs, and achieve environmental sustainability. Governments worldwide, often encouraged by international donors, have formulated devolution policies and legal instruments that provide an enabling environment for devolved natural resource management. However, implementation of these policies reveals serious challenges. This article explores the effects of limited involvement of local people and institutions in policy development and implementation. An in-depth study of the Forest Policy of Malawi and Village Forest Areas in the Lilongwe district provides an example of externally driven policy development which seeks to promote local management of natural resources. The article argues that policy which has weak ownership by national government and does not adequately consider the complexity of local institutions, together with the effects of previous initiatives on them, can create a cumulative legacy through which destructive resource use practices and social conflict may be reinforced. In short, poorly developed and implemented community based natural resource management policies can do considerably more harm than good. Approaches are needed that enable the policy development process to embed an in-depth understanding of local institutions whilst incorporating flexibility to account for their location-specific nature. This demands further research on policy design to enable rigorous identification of positive and negative institutions and ex-ante exploration of the likely effects of different policy interventions.     

Policy instruments for sustainable land management: the case of highland smallholders in Ethiopia

Degradation of land continues to pose a threat to future food production potential in many developing economies. Various approaches, mainly based on command‐and‐control policies, have been tried (with limited success) in the past to encourage adoption of erosion‐control practices by farm households. High transactions costs and negative distributional impacts on the welfare of the poor limit the usefulness of standards and taxes for soil and water conservation. One innovative approach is the use of interlinked contracts which create positive incentives for land conservation. This study analyses the social efficiency of such policies for erosion‐control in the Ethiopian highlands using a non‐separable farm household model. Incentive contracts linked with conservation seem to be promising approaches for sustainable resource use in poor rural economies. This may suggest that conservation programs should give greater consideration to better fine‐tuning and mix of policies that help achieve both economic and environmental objectives.     

NORTH AND SOUTH: PRESIDENTIAL ADDRESS

The limited progress made by the developing countries in securing a New International Economic Order is reviewed, noting “excuses” made by developed countries for lukewarm support or even opposition. Official development aid is defended as a necessary, second best, policy, given trade restrictions by developed countries. It should be greatly enlarged, especially if developing countries would be willing to accept tighter conditions to ensure its economic effectiveness. The remainder of the paper argues the case for a reassessment of the damage done by developed to developing countries by protectionist policies and reviews two controversial areas in the economic analysis of developing economies—rural income distribution and impact of multinational corporations.

Technology,market policies and institutional reform for sustainable land use in southern Mali

To identify appropriate interventions that support sustainable land use; a farm household modelling approach is applied to analyze micro-economic supply reactions to various policy measures. The modelling framework links agro-technical and economic data, and takes both production and consumption decisions into account, allowing land use and production technology adjustments in accordance with farm household objectives. Different types of farm households are distinguished on the basis of their resource endowments, savings coefficients and time discount rate. Actual and alternative (sustainable) cropping and livestock activities for different weather regimes are defined for southern Mali. The effects on sustainable land use and expected farm household welfare of adopting alternative technologies and modifying prices, transaction costs, access to credit and land taxes are demonstrated. Even with full information on sustainable technologies, strong policy interventions are required to halt soil degradation. Structural policies proved to be more effective than price policies to reduce soil degradation while maintaining positive income effects. When prices are determined endogenously, structural policy loses some effectiveness as an incentive for sustainable land use due to the effect of additional supply on local cereal and meat Prices.     

Assessing the effectiveness of rural credit policy on the adoption of integrated crop-livestock systems in Brazil

This study analyzes the effectiveness of rural credit policy to increase the adoption of ICLS. Analyzes are based on a survey with 175 farmers in the State of São Paulo, Brazil. Our estimates suggest that rural credit has positive and relevant impacts on the adoption of ICLS. In turn, the adoption of these systems may also involve investments in fixed capital and increases in operational costs, which create additional demand for rural credit. Other factors, such as access to extension policy, production scale, ex-ante perceptions, and market infrastructure also explain ICLS adoption. The access to rural credit policy is also determined by dependence on farm income, farmer’s perception of transaction costs, and supply of credit in the municipality. The study finally discusses important implications for the devising of rural credit policies and the diffusion of sustainable production systems in developing countries.     

Classical decision rules and adaptation to climate change*

One approach to rationalising policies for addressing potentially catastrophic climate change when such policies may prove unnecessary is to suppose the policies provide a form of social insurance even in the presence of pure uncertainty. Then, provided the policies are effective, such insurance can be justified as a precautionary or minimax response. Even if the policies are potentially ineffective however, intervention can be justified as an attempt to minimise the regret experienced by future generations. This reasoning extends to justify ‘all weather’ policies provided such policies always reduce policy costs. If, however, policy decisions provide ‘all weather’ benefits in only certain states of the world, this rationale breaks down. Minimising regret can establish a case for ‘mixed’ policy responses provided adopting a policy mix precludes the chance that intervention will fail altogether. Precautionary policies and policies which minimise regret are computed for a simple, dynamic, adaptive climate change planning problem and sufficient conditions for policy maker pessimism provided.     

Tribals,Forests and Resource Conflicts in Kerala,India: The Status Quo of Policy Change

One of the constraints in policy analysis of tribal issues in India has been the lack of analytical approaches that have looked at the existential problem of tribal communities in an integrated manner. While restrictive forest policies have played a major role in fomenting tribal unrest in India and other parts of the world, the part played by “poorly designed” development programmes in creating the impasse cannot be ignored. With reference to the District of Wayanad in north Kerala, India, it is argued that natural resource conflicts involving tribal communities have their roots in both restrictive forest policies and misplaced development strategies. While it is true that, in recent times, there has been a serious effort in India to open forests to tribal communities, this has not been accompanied by a change in basic development thinking. It is argued that, for a paradigm change in policy to occur, tribal communities need to be nurtured in forest settings. This is particularly relevant at this juncture, when the ideal of “biodiversity conservation” is considered to be the defining mark of sustainable development in the “natural resource-rich” countries of the South.     

AGRICULTURE IN THE URUGUAY ROUND: AMBITIONS AND REALITIES

Agricultural trade policies are basically a function of domestic policy considerations which have produced high levels of support in many countries. New policy instruments such as direct payments, which are more demanding in terms of information costs but which distort resource allocation less, are becoming more attractive. Unilateral liberalisation is, however, unlikely. Freer trade is a public good which requires international collective action to be provided. Countries which have a clear-cut trade interest in liberalising markets for commodities they export can play the role of catalyst in international co-ordination. The existence of big players is a favourable factor. Hence, the drift of the Round towards a co-ordination of US-EC interests. Both political economy and trade interest considerations suggest that an agreement reached will have its main impact on crops which are widely traded. The main constraining factor of an agreement on EC and US agriculture will be the discipline it will impose on the use of export subsidies. Agriculture will still not come fully under GATT rules which apply to other sectors, but in the future the CAP will be more constrained by international commitments than in the past.     

论南非矿业本土化的立法规制与风险防范

南非是世界五大矿产国之一,也是中国在非洲投资规模最大的国家。南非矿业的增加值约为2305亿兰特,占其G D P的7.3%。矿业已占据中国对南非投资比重的四分之一以上。南非矿业历史悠久,法律制度完善,受殖民主义和种族隔离影响,矿业成为了南非黑人经济振兴政策的重要领域。因此,南非矿业本土化的立法与评估体系对矿业所有权、矿山社区发展、当地采购、住房和生活条件、人力资源开发和就业平等六大方面提出了更高的要求。在赴南非投资矿业的进程中,中国企业必须高度关注其矿业本土化立法的规制,积极做好提升本土化评估等级、履行环境保护义务的举措。     

Multinational Enterprises,Development and Globalization: Some Clarifications and a Research Agenda

This paper considers how economic globalization has affected opportunities and challenges for developing countries in following a multinational enterprise (MNE)-assisted development strategy, revisiting an earlier article by the authors. The growing share of industrial activity owned and/or controlled by MNEs has not—by and large—led to a proportional increase in sustainable domestic industrial growth. Particular attention is paid to how MNEs have responded proactively to globalization by modifying their strategies, spatial organization and the modalities by which they interact with host economic actors, and how these changes alter our understanding of MNEs and development. What has been learnt over the last decade about embeddedness, institutions, inertia, absorptive capacity, spillovers and linkages, and how they can explain the success of some countries (or regions) in promoting growth, and the failure of others, is examined. The need to link MNE and industrial policies systematically is highlighted. Attracting the “right kinds” of MNE activity remains important, but greater heterogeneity of MNE activity and host locations requires greater customization of policy tools.     

Economic growth,convergence, and agricultural economics

After nearly two centuries of lagging behind the industrial countries, growth in many developing countries has surged since the early 1990s. This outperformance has major implications for almost all areas of agricultural economics and, if continued, will likely do so into the future. This article aims to identify the key ways in which the changes in rich and poor country growth rates matter for agricultural economists, as a basis for formulating better research agendas. A key impact arises through sharp increases in demand for agricultural resources as demand for livestock products increases. This changing structure of food demand has important implications for nutrition studies and policies, with the emergence of a double burden of malnutrition. On the supply side, growth in developing countries tends to increase domestic food supply, which is also boosted by increases in research and development spending. Growth in developing countries both stimulates and benefits from increases in infrastructure investment, evaluation of which requires new analytical tools. Negative impacts include the contribution of increased demand for livestock products to global greenhouse gas emissions. In terms of trade policy, growth in developing country is tending to lead to convergence of agricultural policies with the pattern of assistance seen in today's developed countries, raising concerns about the future need to deal with collective action problems, particularly those that increase the volatility of world prices.     

Livestock pricing policy in sub-Saharan Africa: objectives,instruments and impact in five countries

Livestock pricing policies in many developing countries are often instituted without a good appreciation of the consequences of such policies for allocative efficiency, output and trade. This paper evaluates, in a comparative cross-country context, the objectives and instruments of livestock pricing policy in five sub-Saharan African countries: Ivory Coast, Mali, Nigeria, Sudan and Zimbabwe during the period 1970-86. It assesses the extent to which pricing policy objectives have been attained, and also estimates the effects of price interventions on output, consumption, trade and government revenues in order to draw out lessons for the future. The empirical results indicate that in comparison with real border prices, a certain degree of success was achieved in stabilising real domestic producer prices in the study countries. The results also show that since the early 1980s, there has been a gradual shift away from taxation of producers. However, consumers still appear to gain as much as producers in three of the study countries, with negative consequences for foreign exchange earnings and government revenues. The analysis reveals the importance of domestic inflation and exchange rates as key variables for livestock pricing policies and highlights the need to address the macroeconomic imbalances that cause exchange rate distortions and high domestic inflation at the same time that direct price distortions are being tackled.     

Assessing the trade‐offs of increased mining activity in the Surat Basin,Queensland: preferences of Brisbane residents using nonmarket valuation techniques

The mining boom in Australia since 2003 has produced significant economic benefits for regional, State and National economies, creating new job opportunities and revenue flows. Despite the contribution of the resources sector to economic growth, questions are frequently raised about the concomitant negative social, economic and environmental impacts. The Surat Basin in southern Queensland is a traditional agricultural region with a small but growing coal mining sector and a rapidly developing liquefied natural gas industry (mainly associated with extracting coal seam gas). In this paper, the preferences of residents in Brisbane, the State capital, are explored in relation to the relative importance of social, economic and environmental impacts of the resource boom in the Surat Basin. A choice modelling experiment was conducted to assess the trade‐offs Brisbane residents would make (in monetary terms) between the economic benefits and the associated costs of increased mining activity on local communities. The results identify the strength of concerns about community and environmental impacts and can potentially be used to help evaluate the net benefits of resource development.

The literature on the economic causes of and policy responses to obesity

This paper discusses economic perspectives on obesity, summarizes the economic literature and outlines potential policy responses. The paper provides the most up-to-date review of the literature. The literature illustrates the potential role of informational market failures and the dichotomy between the private and social costs of obesity. Market failures can act to provide a rationale for government intervention. Suggested factors for explaining the increase in the prevalence of obesity are discussed as relating to imperfect information, lifestyle changes and technology changes. Some of the potential remedial policies that are being debated in the literature include applying Pigouvian taxes, labelling regulation and advertising limitations.     

Multifunctionality and Agricultural Trade Negotiations

Differing views of multifunctionality—attributing nonmarket benefits to agricultural production—continue to be an obstacle in World Trade Organization (WTO) negotiations. Some nations see multifunctionality as justifying subsidies to agricultural production; others see it as disguised protection. This paper shows that while multifunctionality never justifies trade interventions, it can justify production subsidies or taxes. Recognizing that the subsidies or taxes can be economically efficient policies, nations must precisely define and value the externalities in order to design policies and defend those interventions in the WTO. Trade rules are developed that accommodate domestic policy intervention while preventing disguised protection.     

Impact and implications of price policy and land degradation on agricultural growth in developing countries

In many developing countries, a high proportion of the population resides and works in rural areas. Agriculture is the dominant sector in rural areas and has the greatest concentration of poverty: landless workers, small tenant farmers, and small farm owners. Thus, any development strategy that is directed towards increasing employment and alleviating a country's hunger must concentrate on sustainable agricultural growth. Historically, economic development in most countries has been based on exploitation of natural resources, particularly land resources. Soil erosion and land degradation have been serious worldwide. Due to reasons such as high population pressure on land and limited fossil energy supplies, land degradation is generally more serious in the developing world. Empirical studies show that soil erosion and degradation of agricultural land not only decrease the land productivity but they can also result in major downstream or off-site damage which may be several times that of on-site damage. In promoting industrialization, governments of many developing countries adopt a package of price and other policies that reduce agricultural production incentives and encourage a flow of resources out of agriculture. Increasing evidence shows that these policies cause a substantial efficiency or social welfare loss, and a great loss in foreign exchange earnings. In addition, a World Bank study on the effect of price distortions on economic growth rates concluded that neither rich resource endowments, nor a high stage of economic development, nor privatization are able to make up the adverse effects caused by high price distortions. This analysis is primarily concerned with identifying the factors that determine the agricultural production growth rate and in testing the effects these factors have on agricultural growth in developing countries. Specifically, this study involves statistical estimation of an aggregate agricultural growth function based on cross-country data for 28 developing countries. Special attention is devoted to land degradation and agricultural pricing policy, and to the policy implications resulting from the effects these variables have on agricultural and food production growth. The overall results of this study show that price distortions in the economy and land degradation had statistically significant negative impacts while the change in arable and permanent land was positively related to the growth of agricultural production and food production in 28 developing countries from 1971 to 1980. These results emphasize the importance of ‘getting prices right’ and implementation of sustainable land and water management practices if future growth in food and agricultural output is to be realized and sustained in developing countries.     

Towards a theory of policy timing*

The article presents a theory of policy timing that relies on uncertainty and transaction costs to explain the optimal timing and duration of policy reforms. Delaying reforms resolves some uncertainty by gaining valuable information and saves transaction costs. Implementing reforms without waiting increases welfare by adjusting domestic policies to changed market parameters. Optimal policy timing is found by balancing the trade‐off between delaying reforms and implementing reforms without waiting. Our theory offers an explanation of why countries differ with respect to the length of their policy reforms and why applied studies often judge agricultural policies to be inefficient when actually they may not be.
