Climate change and Australia's comparative advantage in broadacre agriculture1

Australia has long been a major exporter of the products of broadacre agriculture, a production system well suited to the economic and climatic conditions of the country. Presumably, it holds a comparative advantage in these products, among which grain crops and grazing livestock predominate. However, the future plausibility of this proposition is sensitive to the projected impacts of climate change. This article develops a framework to quantify the future patterns of comparative advantage in broadacre agriculture, given the projections of several global climate models. We find empirical support for the conventional wisdom, and note substantial resilience and robustness in Australia's comparative advantage under a number of scenarios.     

Some Consequences of the 1994–1995 Coffee Boom for Growth and Poverty Reduction in Uganda

This paper reports a computable general equilibrium analysis that explores the consequences of the 1994–1995 increase in the international price of coffee for Uganda's economy. Evidence is found for a small effect on both medium‐term growth and poverty reduction. Aid dependence is among the reasons why this effect is not found to be larger. Major beneficiary groups are not primarily the farmers to which the windfall initially accrued, but urban wage earners and the urban self‐employed.     

Economywide effects of climate‐smart agriculture in Ethiopia

Climate‐smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under climate change. Few studies, however, quantify at the national scale CSA's economic effects or compare CSA to input‐intensive technologies, like fertilizer or irrigation. Such quantification may help with priority setting among competing agricultural investment options. Our study uses an integrated biophysical and economic modeling approach to quantify and contrast the economywide effects of CSA (integrated soil fertility management in our study) and input‐intensive technologies in Ethiopia's cereal systems. We simulate impacts for 20‐year sequences of variable weather, with and without climate change. Results indicate that adopting CSA on 25% of Ethiopia's maize and wheat land increases annual gross domestic product (GDP) by an average 0.18% (US$49.8 million) and reduces the national poverty rate by 0.15 percentage points (112,100 people). CSA is more effective than doubling fertilizer use on the same area, which increases GDP by US$33.0 million and assists 75,300 people out of poverty. CSA and fertilizer have some substitutability, but CSA and irrigation appear complementary. Although not a panacea for food security concerns, greater adoption of CSA in Ethiopia could deliver economic gains but would need substantial tailoring to farmer‐specific contexts.     

Registration and release of customary-land for private enterprise: Lessons from Papua New Guinea

Land held under customary tenure has proven difficult to register and release for private enterprise globally. This is because the costs of developing secure rights to land held under communal ownership is high given that such ownership rules out a ‘pay-to-use-the-property’ system while punitive negotiation and policing costs make a ‘pay-him-not-to-use-the-property’ system ineffective (Demsetz, 1967, p. 355). Here I document reforms to institutions governing access to land held under customary title in Papua New Guinea that has imbedded collective ownership whilst allowing for a ‘pay-to-use-the-land’ for private enterprise. Reforms put in place over the past decade have allowed for voluntary incorporation of landowning clans, the registration of their land, and the leasing of this land for up to 99 years. The ongoing reforms provide lessons both for Papua New Guinea and for others wrestling with the challenges of making available land held by customary groups for individual enterprise.     

Australia and resources in the Asian century

The Australian Government's White Paper ‘Australia in the Asian Century’ is the first large‐scale official look in the twenty‐first century at economic change in Asia and how it affects Australian opportunities and challenges. This paper comments on the analysis embodied in and the objectives defined by the White Paper, especially as it relates to Australian resources. This paper generally endorses the aspirations of the White Paper and notes that their achievement is going to require efforts and changes beyond those that are currently contemplated. It comments briefly on six things: the development context of twenty‐first century Asian growth; growth and structural change in Asia and Australia's terms of trade; macroeconomic management of a resource‐intensive Australian economy; restoring productivity growth; excellence in education; and linking Australia to Asian opportunity.     

GM crop technology and trade restraints: economic implications for Australia and New Zealand*

How much might the potential economic benefit from enhanced farm productivity associated with crop biotechnology adoption by Australia and New Zealand (ANZ) be offset by a loss of market access abroad for crops that may contain genetically modified (GM) organisms? This paper uses the Global Trade Analysis Project (GTAP) model to estimate effects of other countries' GM policies without and with ANZ farmers adopting GM varieties of various grains and oilseeds. The gross economic benefits to ANZ from adopting GM crops under a variety of scenarios could be positive even if the strict controls on imports from GM‐adopting countries by the European Union are maintained, but not if North‐East Asia also applied such trade restaints. From those gross economic effects would need to be subtracted society's evaluation of any new food safety concerns and negative environmental externalities (net of any new environmental and occupational health benefits), as well as any extra costs of segregation, identity preservation and consumer search.     

Pesticide‐handling practices: the case of coffee growers in Papua New Guinea

Pesticide mismanagement potentially has high risks for farmers, households living in the community and the environment. In Papua New Guinea where farming is the primary occupation, there is evidence of dangerous herbicide application methods being used by coffee growers. Using original survey data for coffee smallholders from four provinces, we assess the factors driving farmers' use of personal protective equipment when preparing and applying herbicides, and farmers' disposal of agro‐chemical containers. We control for households' demographic variables and measure the impact of farmers' training in pest and disease management. We use the special regressor method to estimate binary choice models featuring an endogenous binary regressor (training). Our results show that human capital (education) and training are important drivers of farmers' pesticide‐handling practices, with marginal effects estimated at 10 and 22 per cent, respectively.     

Poverty analysis in the lowlands of Papua New Guinea underscores climate vulnerability and need for income flexibility*

A severe El Niño event in 2015/16 decimated an important share of Papua New Guinea's (PNG) local crop production, leaving 10 per cent of the population with significant food shortages. Lack of recent socio‐economic data and analysis of the country's rural population impeded efforts to plan and mitigate the ensuing food crisis. This paper presents the most recent poverty analysis in Papua New Guinea in nearly a decade, and a renewed effort to inform rural production, consumption and livelihood patterns in some of the country's most remote, lowland areas. We designed a rural household survey that collected detailed consumption and expenditure data to explore poverty prevalence and correlates of per capita household expenditure. Results suggest that approximately half of the sampled individuals live in households with total per capita expenditures below the poverty line. Climate shocks have significant and possibly long‐term consequences for household welfare. Households that experienced a drought in the last 5 years are associated with significantly lower per capita expenditures. Labour diversification, via migration, is associated with greater welfare. Households with at least one migrant member are associated with 13 per cent greater per capita expenditure.     

Developing Countries and the Gains from Regionalism: Links between Trade and Farm Policy Reforms in Mexico

We use a multi–country computable general equilibrium (CGE) model with agricultural policy details to simulate the effects of North American Free Trade Agreement (NAFTA). We find that Mexico gains from NAFTA only when it also removes domestic distortions in agriculture. In that case, agriculture can generate allocative efficiency gains large enough to offset the terms of trade losses that arise because Mexico has higher initial tariffs than its NAFTA partners. When an RTA forces a developing country to reform its domestic distortions that are linked to trade restrictions, it becomes a building block toward multilateralism.     

Revisiting the relationship between land price and parcel size in agriculture

Hedonic land price models often use parcel size as an explanatory variable. Empirical analyses, however, are rather ambiguous regarding the direction and the size of the effect of this variable on farmland values. The objective of this paper is to investigate this size–price relation for agricultural land use in detail and to derive recommendations for an appropriate specification of hedonic land price models. Our analysis consists of three steps. First, we conduct a meta-analysis based on a comprehensive literature review. Second, we analyze a dataset of more than 80,000 agricultural land transactions in Saxony-Anhalt, Germany, using the nonparametric locally weighted scatterplot smoothing (LOWESS) estimator. This unconditional smoothing algorithm identifies negative size–price relations for very small and large plots, whereas it finds a positive relation for medium plots. We use this finding in our third step, a hedonic land price model, in which the size–price relation is modeled conditional on land and buyer characteristics. From these steps, we conclude that the complex relationship between land price and plot size cannot be captured by a simple functional form since it is affected by several economic factors, such as economies of size, transaction costs, and financial constraints.     

Food insecurity,income inequality,and the changing comparative advantage in world agriculture

I would like to argue in this article that in the process of economic development in land‐poor countries in Asia, agriculture faces three distinctly different problems: food insecurity, sectoral income inequality, and the declining food self‐sufficiency associated with the declining comparative advantage in agriculture at the high‐income stage. Massive imports of food grains to Asia, if they occur, will aggravate the world food shortage, which will have significant implications for the poverty incidence in the world. I argue that in order to avoid such a tragedy, Asia should expand farm size to reduce labor cost by adopting large‐scale mechanization, sub‐Saharan Africa should realize a green revolution in grain production, and Latin America should further expand its grain production capacity.     

Labour-saving technologies in smallholder agriculture: An economy-wide model with field operations

Labour-saving technologies are relevant for agricultural development. Yet, as this study shows, they are poorly integrated into agricultural production functions of economy-wide models. We report a computable general equilibrium (CGE) model, which explicitly incorporating field operations (e.g. land preparation, weeding or harvesting) in the context of smallholder agriculture. The field operations approach allows to model technological trade-offs in organic and conventional production systems at various stages of the agricultural production process. Simulating a structural change scenario, we compare the performance of the field operations approach with published benchmark production structures by assessing how they replicate empirically observed changes in land and agrochemical use. This benchmark analysis shows that incorporating field operations replicates the observed empirical changes most accurately and allows for more realistic modelling of labour-saving technologies. We use the field operations model to investigate three policy options to mitigate labour shortages in the agricultural sector of Bhutan. Permitting the employment of Indian workers in agriculture has the highest short-term potential in this respect. We find that subsidising agricultural machinery hiring services and removing import tariffs on agrochemical inputs are found to be less effective. Further options for model developments, such as combining field operations and labour market seasonality, are highlighted.     

Community‐supported agriculture in the United States: Social,ecological, and economic benefits to farming

In the United States, there is a tremendous amount of interest in community‐supported agriculture (CSA) among farmers, consumers, activists, and policymakers. Despite the attention garnered by CSA and the resurgence of local agriculture, relatively few studies have examined the livelihood opportunities for farmers within local agriculture. This paper evaluates the livelihoods of CSA farmers from the farmers' perspective in the Connecticut River Valley of Massachusetts. Results indicate that although CSA farmers earn more farm income than other farms across the United States on average, they still earn far below the median national income and generally fail to earn a living wage. Despite these findings, CSA farmers stressed the importance of the broader social, ecological, and economic benefits to farming. Although these non‐market benefits are a significant source of well‐being from the CSA farmers' perspective, CSA has largely failed to provide adequate livelihoods for farmers to date.     

Contrasting Quantitative and Qualitative Approaches to Rural Development Analysis: The Case of Agricultural Intensification in Lebanon

While peripheral rural regions in Lebanon face typical problems of lagging development and economic marginalisation, they have not been regarded as a priority for policy‐makers. Local extensionists have encouraged technological innovation as a means of improving farmers’ livelihoods, and this has led to increasing input use and an intensification of agricultural production. This paper applies contrasting quantitative and qualitative methodologies to analyse the effects of such changes at the level of the overall economy of Lebanon and also to explore the impacts on rural households. A computable general equilibrium (CGE) model simulates shocks in which agricultural output increases due to different types of intensification. The results are contrasted at local level through the use of qualitative case study analysis carried out in the Hermel district of northeast Lebanon. Quantitative simulations indicate that, while agricultural intensification has a positive effect overall on the Lebanese economy, the effects on rural households and the income of farmers are negative. The case‐study interviews demonstrate that, at local level, agricultural trade liberalisation, increased agricultural output and greater volatility of commodity prices have resulted in farmers opting for lower input use and more secure market forms of production.     

Conversion subsidies for organic production: results from Sweden and lessons for the United States

Organic conversion subsidies used in Europe are less likely to be politically acceptable in the United States, where organic agriculture development is market‐driven. Persistent barriers to conversion in the United States include limited availability of and access to production and market information, training in management systems and cost of conversion‐related investments. By determining whether these factors affect the requirement of a subsidy to convert, we can suggest whether U.S. policy makers need to provide subsidies to encourage conversion and identify policy variables consistent with market‐based approaches that could stimulate conversion. A utility difference model is used with Swedish data to analyze factors that determine whether a subsidy is required to motivate organic conversion. The results show that farmers requiring subsidies manage larger less‐diversified farms and are more concerned with organic inspection, quality, and adequacy of technical advice. Access to more market outlets and information sources substitutes for payment level in the farmer's utility function, indicating that services rather than subsidies may be used to encourage organic agriculture. To the extent that conditions are similar in the U.S. organic sector, market‐based programs such as cost‐sharing for conversion and market access improvement should stimulate growth of this industry.     

Productivity and international competitiveness of agriculture in the European Union and the United States

This study looks at international competitiveness of agriculture in the European Union and the United States. The most intuitive concept is that of price competitiveness. We calculate relative prices for 11 member states of the European Union and the United States for the period 1973–2002. We assume that markets are perfectly competitive and in long‐run equilibrium, so that the observed price always equals average total cost, as measured by the cost dual to the production function. This assumption is used in our calculation of relative competitiveness and productivity gaps between the European Union and the United States and in our decomposition of relative price movements between changes in relative input prices and changes in relative productivity levels.     

Agricultural land in the Eastern Caribbean: From resources for survival to resources for development

The main effects of existing socioeconomic arrangements for agricultural land development in the Eastern Caribbean are discussed and changes aimed at improving both the efficiency and equity of the land development process are identified. The author argues that the existing ‘plantations-small holders’ structure is incapable of providing an efficient way of developing the available land resources and of improving the standard of living for the vast rural population. A new set of export oriented agricultural enterprises is pinpointed as a requirement in any viable solution aimed at taking land away from its present role as a resource for survival for the many and an economic benefit for the few and to reinstate agricultural lands as one of the key resources for more egalitarian, environmentally sound and efficient socioeconomic development.     

Bubbles,Froth and Facts: Another Look at the Masters Hypothesis in Commodity Futures Markets

The Masters Hypothesis suggests that long‐only index funds were the main cause of a massive increase in commodity prices in 2007–2008 and 2011–2012. Central to the Masters Hypothesis are three basic tenets: (i) long‐only commodity index funds were directly responsible for driving futures prices higher; (ii) the deviations from fundamental value were economically very large; (iii) the impact was pervasive across commodity futures markets. There has been a great deal of empirical research on the Masters Hypothesis and commodity market bubbles. However, surprisingly few studies have found evidence that directly support the main tenets of the Masters Hypothesis. Some have attributed the lack of supporting evidence to the low‐power of time‐series tests, market efficiency issues and a lack of conditioning variables within models. In this paper, we address each of these issues using updated data and new empirical approaches. Still, price behaviour consistent with the Masters Hypothesis is surprisingly difficult to find in the data. This is an important finding given the on‐going policy debate and regulations proposed or being implemented to limit speculative positions in these markets.     

Economic and Household Impacts of Projected Policy Changes for the Irish Agri‐food Sector

The policy environment for the Irish agri‐food sector could change rapidly in the coming decade. A potentially positive factor will be the elimination of milk quotas in 2015, although a potentially negative factor will be further trade liberalisation and increased import competition. These changes come on top of the move to decouple direct aids to farmers in 2005 as part of the Mid‐Term Review of the EU's Common Agricultural Policy agreed in 2003. This paper examines these reforms and their impacts on the Irish economy and income distribution using a CGE model particularly rich in detail on the agri‐food sectors, differentiated household groups, and agricultural policy instruments including their links to productive factors and households. The results suggest that the past and projected changes in the policy environment have, in sum, a small positive impact on GDP and household income. However, the gains and losses are unequally distributed across sectors and household groups due to the highly differentiated distribution of support and protection. Although all households generally gain from the sequence of policy reforms in the long run, some experience strong adverse effects from particular reforms and in the medium term.
