Insider trading is a much studied form of market manipulation in the financial market literature. However, studies addressing the issue of insider trading in resource markets, and in particular water markets, are rare. This study investigates the occurrence of insider trading practices around important water market allocation announcements in the Goulburn temporary water market trading zone in the Murray–Darling Basin, Australia, which is one of the largest and longest operating water market districts in the world. Nine years of daily water allocation volume and price transactions between 2008 and 2017 are modelled, with some evidence found of abnormal price movements in the 3 or 5 days preceding water allocation announcements, and especially before the introduction of insider trading rules in 2014. However, although the results do suggest some very weak statistically significant evidence that insider trading may still be present in Goulburn water markets post‐2014, it is just as feasible that our results may also reflect an increased sophistication of trader behaviour over time.  相似文献

A slowdown in the rate of agricultural productivity growth is thought by many observers to be contributing to the recent rise in agricultural prices. In this article I decompose sources of output growth in global agriculture into aggregate input and total factor productivity (TFP) components and examine whether productivity growth slowed substantially in the years leading up to the recent rise in commodity prices. Contrary to widely held perceptions, I find no evidence of a general slowdown in sector‐wide agricultural TFP, at least through 2006. If anything, the growth rate in agricultural TFP accelerated in recent decades. However, the results do show a slowdown in the growth of agricultural investment. Accelerating TFP growth largely offset decelerating input growth to keep the real output of global agriculture growing at about 2% per year since the 1960s. Regionally, however, agricultural productivity performance has been uneven. These findings have important implications for the appropriate supply‐side policy response to the current agricultural price crisis.  相似文献

The US meatpacking industry has become concentrated to a degree not experienced since the days of the ‘Beef trust’ a century ago. A number of mainstream studies have investigated if such concentration has been detrimental to competition. Just as earlier studies may have helped shape competition policy towards meatpacking a century ago, contemporary studies have made their way into current discussions and may shape competition policy at the turn of this century. This paper asks whether or not contemporary studies are useful in informing competition policy. After comparing how competition looks from the econometric vantage point with how it looks from the vantage point of the industry's 300-yr history, this article concludes that mainstream studies are more useful for a competition policy targeting conduct rather than structure.  相似文献

This article estimates agricultural productivity growth in 10 South American countries in 1969–2009 with the objective of investigating if the slowdown being measured in other countries is present in the region. Results show that productivity growth accounts for half of the three‐fold increase in agricultural output during this period and that performance is sensitive to R&D investments in the sector. The slowdown found for the 1990s to 2000s in the U.S. and some European economies does not seem to be present yet in South America. The region's total factor productivity (TFP) growth rate increased steadily from 1.07% during the 1970s to 2.29% during the 2000s. Given lags in adoption and the adaptive nature of innovations in these economies, we have yet to see the potential effects in South American agriculture of decreases in R&D in advanced economies.  相似文献

This research aims to identify the specific characteristics of small farms in developed countries and the factors that influence their survival and growth. Using the case of France, we employ statistical and econometric analysis of data from the Farm Structure Survey (N = 70,000) for the period 2000–2007. The principal findings suggest that small farms are no more likely than other farms to employ “alternative” strategies to the predominant model of increasing farm size, nor are they more likely to diversify on‐farm activities or operate under quality‐labeled production systems, with the notable exception of organic agriculture. However, where small farms do adopt or practice these activities, they are seen to have a favorable effect in ensuring their survival and growth. In contrast, we are unable to conclude that pluriactivity of farm households has a positive impact on the survival of small enterprises. The effect of geographical location on small farms is largely expressed in their concentration in mountainous or disadvantaged regions. Overall, the trajectory of small farms is marked by farm exit, principally as the result of farmers retiring at the end of their careers. The small farm sector is also revitalized by both larger farms declining and thus being reclassified as small farms, as well as the progressive entry into agriculture of small farm holders whose income was previously derived largely off‐farm.  相似文献

In the 1990s, the Democratic People’s Republic of Korea (North Korea) suffered from severe food shortages and large-scale deforestation, which triggered a stage of rural conservation reform. Since 2004, with support from the Swiss Agency for Development and Cooperation (SDC), North Korea’s Ministry of Land and Environmental Protection (MoLEP) has implemented a Sloping Land Management Program (SLMP). The SLMP established sloping land user groups and granted these groups the right to use marginal land for agroforestry development. This devolution of land rights from state control onto local groups is a landmark in North Korea, and this decentralization initiative has now expanded to over eight counties to involve thousands of households. It has also led to the launch of a National Agroforestry Policy and Strategy. Drawing from both qualitative and quantitative data collected from 2008 to 2014, this paper documents the process and effects of the SLMP. It argues that the decentralization reform in land management has contributed to not only food security with increased food crop diversity and productivity, but also notably forest recovery through an expansion of tree plantations and agroforestry practices on degraded sloping lands. However, an insufficient power transfer in the form of a lack of timber rights granted to the local user groups has hampered the effectiveness of the SLMP. There are also institutional and geopolitical challenges that are limiting further scaling-up of land-use decentralization across the country. The policy implication calls for more international investment as well as national land-use policy reforms in order to promote and facilitate further decentralization of sloping land management and to secure greater use rights for sloping land user groups.  相似文献

The continuity of farming in mountain areas in Europe is at severe risk and its future faces manifold uncertainties. Mountain farms are immersed in a long-term process of reorganization. Farm diversification plays a prominent role in this process of adjustment and reallocation. However, little work has been done explicitly on the role farm diversification plays in the current structural changes occurring. In order to fill this void, the nature of farm diversification has been examined in the Pyrenees, where four different typologies of farms have been identified: absence of diversification, agricultural diversification, farmland diversification and finally farm labour diversification. These typologies reflect a gradation along which the farm diversification practices are applied to more aspects of the farm household. Throughout this gradation farming is increasingly marginalised. Finally, it is argued that the endorsement of policy measures stimulating farm diversification in mountain regions should be cautiously considered, since there is high risk of encouraging further agricultural abandonment.  相似文献

We address a new agricultural policy concern following the decoupling of CAP direct payments in 2005: passive farming, whereby landowners maintain their agricultural area to collect payments without producing commodities. It is claimed that passive farming is hindering agricultural development by ‘blocking’ access to farmland for expanding farmers. We evaluate the links between the EU's Single Payment Scheme (SPS), passive farming, land use and agricultural development. Following identification of the rational landowners’ optimal land‐use choice, we evaluate the effects of the SPS using a spatial, agent‐based model that simulates farmers’ competition for land in a case‐study region of Sweden. We show that passive farming does not constrain land from being used in production; on the contrary more land is used than would be the case without the SPS. We conclude that passive farming is not a problem for agriculture, but provides public goods that would otherwise be under provided: preservation of marginal farmland and future food security. However SPS payments on highly productive land inflate land values (capitalisation) and slow structural change, which hinder agricultural development. Consequently CAP goals could be better served by targeting payments on marginal land and phasing out payments to highly productive land.  相似文献

The European Union (EU) and the Mercosur countries resumed negotiations on trade liberalization in May 2010 after several years of interruption. The article analyzes who stands to benefit and who is likely to lose if the EU liberalizes Mercosur's access to domestic beef markets. This economic assessment is performed using a partial equilibrium model for beef operating at a low level of product aggregation, paying specific attention to the role of Tariff Rate Quotas (TRQs). Consultations with experts from the meat sector allowed us to identify the allocation of the quota rents to different stakeholders. Under an agreement based on the EU's negotiation proposal, trade impacts are projected to be small due to the present quota overfill. As expected, impacts are more pronounced under the conditions set out in Mercosur's proposal. The results confirm that the distribution of quota rents can be decisive in determining welfare effects.  相似文献

We assess the effects of the dramatic rise in agricultural commodity prices during 2007–2008 on income dynamics and poverty among rural households in Bangladesh. A unique panel data set allows us to put the effects of recent events in the context of long‐run trends in income and poverty. We use data from a nationally representative longitudinal survey of rural households in Bangladesh collected in four waves in 1988, 2000, 2004, and 2008. Nargis and Hossain (Nargis, N., Hossain, M., 2006. Income dynamics and pathways out of rural poverty in Bangladesh, 1988–2004. Agric. Econ. 35, 425–435) analysed income dynamics and poverty incidence for the first three waves, finding a declining trend in both the incidence and severity of poverty, aided in particular by human capital development and off‐farm employment opportunities. We update and extend the analysis to include data collected in 2008, at the height of a spike in agricultural prices. We find that the price of a balanced food basket increased by more than 50% during 2000–2008, while household income rose only 15%. As a result the incidence and severity of rural poverty in Bangladesh sunk to pre‐2000 levels during 2004–2008. Thus, the price spikes in 2007–2008 helped push an additional 13 million people into poverty in rural Bangladesh. Moreover, we find that the determinants of poverty have not been time‐invariant. In particular, agricultural production, which had previously been associated with a higher incidence of poverty, served as a hedge against higher food prices during 2004–2008.  相似文献

The question addressed in this paper is whether Prairie agriculture has become like any other industry. The implication is that a positive response would lead to the conclusion that it should therefore be treated like any other industry rather than being accorded the special status that it has enjoyed for more than a century
We show that, as net farm incomes have declined over the past 35 years, Prairie farmers have responded by seeking other (non-farm) sources of income. At the time of the 1996 census, net farm income accounted for only 31 percent of farm family income (down from 75 percent in 1967). By 1999, the contribution of net farm income was even lower than in 1996
In spite of the dwindling contribution of net farm income to farm family income, average farm family income in Saskatchewan has exceeded average provincial household income for all but two years between 1971 and 1998, Under these circumstances, it is necessary to ask why it is in the public interest to subsidize an activity which, in recent good times, produced 31 percent of the income of a subset of the population whose household incomes were 10–15 percent above the provincial average
Based on income levels, it is probably no longer necessary to accord farm families special status in the public policy arena. However, other policy considerations (immobility of resources, the role of agriculture in the rural economy, environmental considerations, food safety and security, for example) remain, differentiating agriculture from other industries  相似文献

The current study explains why Dutch forest expansion policy is at risk of failure. To study the forest expansion implementation process we have chosen to further operationalize Matland's policy type implementation model to an extended and comprehensive typology of relevant implementation characteristics. In addition, a case study methodology with mixed-method design was used to collect and analyze the data. The Dutch forest expansion policy is currently an example of symbolic implementation. The symbolic implementation is a consequence of the absence of central guidance, the legislative complexity, the low policy stability, the lack of supporting conditions for policy innovation, the lack of regulatory responsiveness and the latent policy at state level and in many provinces. Nevertheless, the transferable development rights method of the province of Limburg is a promising innovation and forest expansion still happens, which is mainly the result of a good internal and external communication, an effective actor network of forest expansion advocates and the willingness to realize negotiated project aims that lead to a win–win situation for all actors involved. Nonetheless, it is expected that the forest expansion targets will be not reached, unless most of the above shortcomings are solved.  相似文献

This paper focuses on three decades of agrarian reform policies and the resulting peculiarity of the development trajectory in Bangladesh. I interrogate the ways in which the reforms have led to a paradoxical situation consisting of partial protelarianization in attempting to promote a market‐based economy. I contend that the particular positioning of the state is central to understanding this dialectic between proletarianization and the persistence of small peasants amid a huge rush towards the formation of a capitalist market economy. I conclude that the partial nature of agrarian transformation that we now experience in Bangladesh may not be resolved in favour of a complete proletarianization of small peasants in the foreseeable future.  相似文献

With the sustainable development goals has come a renewed global interest in ending hunger and achieving food security, while preventing natural resource degradation. Despite this renewed interest and increased commitments to invest in agricultural development, there is an outstanding debate over the technological trajectories to sustainability. The debate centres on sustainable agricultural intensification (SAI) and agroecological intensification (AEI) pathways to agricultural sustainability. Using a systematic literature review approach, this study examines the debate over AEI and SAI. This study employs a theoretical framework based on the economic, social, and ecological dimensions of sustainable agriculture within a policy and institutional space. Based on the sustainability dimensions, a discourse analytical technique is applied to unravel the debate. The results reveal differences in actor composition in the SAI and AEI pathways. Both pathways aim to promote food security with optimal and sustainable use of inputs; however, the actors differ on discourse relating to the concept of farming, the role of genetic engineering, the scale of operation, land use and soil health. Resolving these differences requires a blended sustainability approach that moves beyond the current AEI and SAI debate by acknowledging the tradeoffs and synergies of the socio-economic and ecological dimensions.  相似文献

The global bioenergy market has considerable impacts on local land use patterns, including landscapes in the Southeastern United States where increased demand for bioenergy feedstocks in the form of woody biomass is likely to affect the management and availability of forest resources. Despite extensive research investigating the productivity and impacts of different bioenergy feedstocks, relatively few studies have assessed the preferences of private landowners, who control the majority of forests in the eastern U.S., to harvest biomass for the bioenergy market. To better understand contingent behaviors given emerging biomass markets, we administered a stated preference experiment to private forest owners in the rapidly urbanizing Charlotte Metropolitan region. Respondents indicated their preferences for harvesting woody biomass under a set of hypothetical market-based scenarios with varying forest management plans and levels of economic return. Our analytical framework also incorporated data from a previously-administered revealed preference survey and spatially-explicit remote sensing data, enabling us to analyze how individuals’ ownership characteristics, their emotional connection the forests they manage, and the spatial patterns of nearby land uses, influence willingness to grow bioenergy feedstocks. We found conditional support for feedstock production, even among woodland owners with no history of active management. Landowners preferred higher economic returns for each management plan. However low-intensity harvest options were always preferred to more intensive management alternatives regardless of economic return, suggesting that these landowners may be more strongly motivated by aesthetic or quality-of-life concerns than feedstock revenues. Our analysis indicated preferences were dependent upon individual and environmental characteristics, with younger, more rural landowners significantly more interested in growing feedstocks relative to their older and more urban counterparts. While this study focuses on one small sample of urban forest owners, our results do suggest that policy makers and resource managers can better inform stand-level decision-making by understanding how feedstock production preferences vary across populations.  相似文献

Taking a capability approach perspective, our paper aims at advancing our understanding of poverty in Afghanistan, and at identifying the most deprived, including persons with disabilities, in order to address the first Sustainable Development Goal to eradicate poverty in all its forms. We used data from a national survey carried out in Afghanistan in 2005. We calculated one index using two weights structures, the adjusted headcount ratio, part of the multidimensional poverty measures. Following a participatory process, we identified and validated 13 indicators clustered in seven dimensions of poverty, including three usually neglected dimensions. Findings suggest that exploring various domains of deprivation would better inform poverty eradication policies than an approach focused only on income. Our results also demonstrate that nearly all Afghan adults are deprived in at least one dimension and those residing in rural areas, from minority ethnic groups, women, elderly people and persons disabled at birth or of an unknown cause are the poorest of the poor. Efforts to improve well-being must acknowledge these inequalities so that public policies in Afghanistan aiming at alleviating poverty take these disparities into account, when facing a reduction in available resources.  相似文献
