The wealth of nature: economics as if survival mattered

Livestock play a key role in the lives of poor, rural people in developing countries, providing a major proportion of their cash income, capital assets, draught power, fuel and fertilizer. Rapid growth in demand for meat and dairy products in Asia presents both opportunities and challenges for livestock development and poverty alleviation. This paper explores the potential of livestock intensification to benefit the livelihoods of upland households and meet market demand in the Lao Peoples' Democratic Republic (Lao PDR), a South East Asian country undergoing significant economic change.

A review of the livestock sector in Asia shows increasing demand for live animals and meat in neighbouring Vietnam, Thailand and China. Lao PDR is well positioned to capitalize on the growing Asian livestock sector, however the extent livestock production in Lao PDR can reduce poverty, meet growing domestic meat demand and lift livestock exports is problematic. Findings from research in two upland northern provinces demonstrate how the introduction of forages for livestock has revolutionized the lives of some farmers and villages, but concludes that strategies are still needed to engage poorer households. The impacts of changing domestic and export markets are less certain, and are discussed within the context of environmental and public health, cultural traditions, economic development and sustainable livelihoods.     

Investing in irrigation development in North West Queensland,Australia

This study uses a dynamic multi‐regional Computable General Equilibrium model of the Australian economy to examine the impacts of developing irrigated agriculture in remote North West Queensland. A potential investment and operational scenario is implemented using three alternative forecast baselines. In the first run using a business‐as‐usual baseline, there is a welfare loss from irrigation development, even with an optimistic shift in farm productivity and factor endowments in North West Queensland. In the second run, baseline demand for Australia's exports is assumed to grow at a faster rate and there is a small welfare gain. Simulating climate change impacts on crop yields, the forecast baseline of the third run includes a gradual reduction in farmland productivity in southern Australia. The simulations show the impacts of both supply and demand shifts on the welfare outcome, but on balance, clear welfare gains do not arise from the potential irrigation development.

Quality Upgrades of EU Agri‐Food Exports

We investigate determinants of quality upgrades in EU agri‐food exports using panel data models for the period 2000–2011. By employing highly disaggregated data we show that the unit value of exports is positively correlated to level of economic development and size of population. Our results highlight the negative impacts of comparative advantage and trade costs on upgrades in export quality. Our analysis partly confirms the role of income distribution in quality specialisation, that greater income inequality increases specialisation in quality upgrades. Findings are robust when applied to alternative subsamples, including vertically specialised and final agri‐food products.     

Economics of export subsidies under costly and imperfect enforcement

The present paper builds on the published literature on agricultural policy analysis under costly and imperfect enforcement by introducing enforcement costs and misrepresentation into the economic analysis of export subsidies. Specifically, the present paper examines the economic causes of cheating on export subsidies and the consequences of enforcement costs and misrepresentation for the welfare effects and the transfer efficiency of this policy instrument. Policy design and implementation is modelled as a sequential game between a government that designs and enforces the policy and the recipients of the payments. Two alternative policy implementation scenarios are considered. In the first scenario, export subsidies are paid to private trading firms while in the second scenario subsidies are paid directly to the producers of the subsidised commodity. Analytical results show that the introduction of enforcement costs and cheating changes the welfare effects of export subsidies and their efficiency in redistributing income to producers. The analysis also shows that, contrary to what is traditionally believed, the incidence of export subsidies depends on the group that is subsidised to export the surplus quantity – the way the policy is implemented. The results provide additional support for the contention that the economic consequences of cheating are highly policy-specific. Finally, the analysis reveals that when the government faces restrictions on either the volume or the value of export subsidies, cheating reduces the distortionary effects of the policy on international markets. This is true irrespective of whether subsidies are paid to trading firms or to producers.     

Does China's demand boom curb Australian iron ore mining depletion?

Australia's resources boom is underpinned by increased demand from industrialising China and a rise in export prices. Current depletion rates will soon exhaust currently known reserves of iron ore and coal. This paper presents a dynamic optimisation model of a growing open economy where a social planner chooses the time path for depletion of a non‐renewable resource during a demand‐led resources boom. We find that for particular functional forms and in the absence of extraction and social costs, the optimal depletion rate equals the difference between the price elasticity of export demand times the world interest rate and growth in export demand. In contrast to the existing literature, we show that the optimal depletion rate is unaffected by a temporary increase in price, but reduced by growth in demand which is in turn sustained by offshore steel production and urbanisation. The main theoretical implication is that growth in export demand from China reduces the depletion rate. Australian iron ore exports, simulated using this theory, move together with actual volumes over the period 1995–2011, and the error between simulated and actual iron ore exports is lower for the model in this paper than it is for the model without growth in export demand.     

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.     

A Metamodeling Approach to Evaluate Agricultural Policy Impact on Soil Degradation in Western Canada

A novel approach for integrating economic and environmental models is described in the context of evaluating soil degradation impacts of agricultural policy in western Canada. The key element of this approach is the development of metamodels, which are statistical summary functions of simulation data obtained from carefully designed experiments with physical process models. The metamodels are in turn used to predict the soil degradation impacts of farmers'land management responses to policy options. The metamodels provide flexibility to perform repeated policy scenarios without having to rerun the time-and resource-consuming physical process simulation models. The estimated wind and water erosion metamodels are very robust, with the majority possessing R-square values in the range of 0·80 to 0·97. The efficiency of the metamodels in facilitating the integration of a policy modeling system is described and applied to a scenario of increased crop residue management. Using regional aggregates of net farm income, total economic, surplus (consumer plus producer surplus) and total soil loss the economic and environmental tradeoff between the status quo and a no-till policy scenario is evaluated. The model-predicted economic welfare and environmental quality interaction suggests a clear win-win situation for society under this alternative policy scenario.     

Agricultural exports and economic growth in less developed countries

This article examines the contribution of agricultural exports to economic growth in less developed countries (LDCs). A sources‐of‐growth equation is developed from a dual economy model where agricultural and nonagricultural sectors are both divided into export and nonexport subsectors. This is then estimated using panel data for 62 LDCs for 1974–1995. Results provide evidence that there are significant structural differences in economic growth between low, lower‐middle, and upper‐income LDCs. Investment in the agricultural export subsector has a statistically identical impact on economic growth as investment in the nonagricultural export subsector. The marginal productivities in nonexport subsectors are over 30% lower than those in respective export subsectors. From a policy perspective, the results suggest that export‐promotion policies should be balanced.

The impact of the Asian Crisis on Australia's primary exports: why it wasn't so bad

This article explores the modest impact of the Asian Crisis on Australia's primary commodity exports. Simulations using a global general equilibrium model show: (i) as capital flees Asia, investment in Australia increases and the trade deficit grows; (ii) while terms of trade deteriorate in the short run, they improve in the medium run as import demand increases in the crisis countries; (iii) exports of primary commodities expand as the crisis countries try to export more; (iv) more income-elastic primary commodities fare less well than the income-inelastic foodstuffs as incomes decline in the crisis countries; (v) Australia's relatively low dependence on manufactured exports was a buffer as manufactured exports came under heavy pressure from exports from the crisis countries.     

Price integration in the Australian rock lobster industry: implications for management and climate change adaptation

Rock lobster fisheries are Australia's most valuable wild fisheries in terms of both value of production and value of exports. Different states harvest and export different lobster species, with most of the landings being sent to the Hong Kong market. A perception in the Australian lobster industry is that the different species are independent on the export market, such that a change in landings of one species has no impact on the price of the others. This study investigates the market integration of Australian exports to Hong Kong for the four species and different exporting states. Our results indicate all four species and producers/export states are perceived to be substitutes for one another, so that, in the long run, prices paid to operators in the industry will move together. The integrated nature of the Hong Kong export market for Australian lobster suggests that the potential impacts of alternative fisheries management and development strategies at state and species levels cannot be considered in isolation, at least from an economic perspective. In addition, impacts of external shocks affecting production in one state (e.g. climate change) can be expected to affect all Australian lobster fisheries.

The Economic Impact of U.S. Tobacco Products Exports

The economic impacts of increasing U.S. tobacco exports on the U.S. economy are analyzed. Simulation of expanded exports to South Korea and Thailand are conducted. Over $1.1 billion in economic activity and 12,000 jobs were associated with tobacco export increases to these countries. Declining raw tobacco exports to Thailand, however, offset gains associated with greater cigarette sales. The resultant losses totaled $5.3 million in economic activity and over 378 jobs in the U.S.     

Development Assistance and Exports: The Case of the United States

The relationship of development assistance and exports has been a controversial subject in recent years. U.S. public organizations feel that development assistance, particularly for research, while intended primarily and immediately to encourage economic development in low-income nations, will also help increase the effective demand for agricultural exports. Some commodity-oriented U.S. farm groups, on the other hand, see assistance primarily in terms of leading to increased competition for exports of their product. They would have the U.S.A. provide less international support for agricultural development and they have had some influence. While there has been considerable debate on the subject, this has not yet resulted in the development of an enlightened national policy. The paper attempts to sort out the facts and perceptions that have led to this situation and to provide some policy suggestions. Two important needs are for: (a) greater public understanding, and (b) strengthened domestic research and improved linkages between domestic and international research activities. Paradoxically, the latter point tends to be overlooked by some of the farm groups but is essential if the U.S. is to remain competitive in what is likely to become a more open international market in the future.

Leveling the field for biofuels: comparing the economic and environmental impacts of biofuel and other export crops in Malawi

Biofuels often raise the specter of food insecurity, water resource depletion, and greenhouse gas emissions from land clearing. These concerns underpin the “sustainability criteria” governing access to European biofuel markets. However, it is unclear if producing biofuels in low‐income countries does exacerbate poverty and food insecurity, and moreover, whether the sustainability criteria should apply to all agricultural exports entering European markets. We develop an integrated modeling framework to simultaneously assess the economic and environmental impacts of producing biofuels in Malawi. We incorporate the effects of land use change on crop water use, and the opportunity costs of using scarce resources for biofuels instead of other crops. We find that biofuel production reduces poverty and food insecurity by raising household incomes. Irrigated outgrower schemes, rather than estate farms, lead to better economic outcomes, fewer emissions, and similar water requirements. Nevertheless, to gain access to European markets, Malawi would need to reduce emissions from ethanol plants. We find that biofuels’ economic and emissions outcomes are generally preferable to tobacco or soybeans. We conclude that the sustainability criteria encourage more sustainable biofuel production in countries like Malawi, but are perhaps overly biased against biofuels since other export crops raise similar concerns about food security and environmental impacts.     

An Analysis of the Linkage Between Agricultural Exports and Economic Growth in Pakistan

Summary

This article examines the relationship between agricultural exports and economic growth. Pakistan is used as a case study due to its large amounts of agricultural exports which have competed with industry for government support. This study estimates three simultaneous equations representing GDP, agricultural exports, and total imports while incorporating factors such as income remittances from abroad, investment, and manufactured exports as independent variables. The timing of this information is critical as Pakistan's policy makers now face major agricultural reforms in their quest for development. The estimation results show that a favorable relationship exists between agricultural exports and growth in GDP.
