What the literature leaves open

  • Conclusion This empirical research provides quasi-experimental evidence that the official ASS pilot scheme effectively lifts grain output across Chinese provinces.

  • 143 Yet, as the final section shows, prevailing norms of good financial practice meant even a bespoke system of federal intermediate credit banks was insufficient to shake off the “crop-lien crown of thorns” that farmers still bore despite the Fed’s foundation, because it focused narrowly on trade finance rather than working capital in a broader sense. 156 Figures from earlier years are lacking; however, from 1925 to 1929, cotton was the single largest commodity collateralizing bankers’ acceptances representing goods shipped and warehoused domestically—on average it constituted 36– 50% of the total, followed by grain (13%) and tobacco (7%). Because CMAs customarily only advanced up to 65% of the value of the cotton delivered to them, payments were insufficient to allow producers to reimburse local creditors and release the mortgage on the crop.

  • We encourage agricultural economists to provide further research on detailed cases, which will be particularly important for gaining a better understanding of the potential effects of the EU Green Deal.

    Introduction to the special issue on bioeconomy innovation pipelines and supply chain shocks · 2024 · DOI

  • Additional research is needed to develop standards for SOC change metrics and monitoring, and to better understand the impact of short term, non-permanent carbon removals on peaks in atmospheric greenhouse gas concentrations and on the probability of exceeding climatic tipping points.

    Carbon farming: Are soil carbon certificates a suitable tool for climate change mitigation? · 2023 · DOI

  • Limitations/future research: The research explore the evolutions of the inputs price and investments indices of the products in the European agriculture only form the descriptive analysis without covering an extensive framework or considering other additional variables which consist the main limitation of this study.

    A short descriptive analysis of the European evolutions of input price indices of agricultural products between 2008-2017: Patterns, trends and implications · 2022 · DOI

  • The article shows that this position is too general and unnuanced, because it does not include the general long-term population changes, other economic sectors and the different socio-economic and institutional contexts in member states, as well as being limited to a narrow range and often non-comparable public statistics.

    Does a Demographic Crisis Threaten European and Polish Agriculture? · 2021 · DOI

  • The value of the contribution is increased by the choice of regional scalar perspective, which receives much attention in EU policy rhetoric but has remained scarcely examined and documented.

    The CAP and the Regions: The Territorial Impact of the Common Agricultural Policy · 2008

  • But, and this fact is little known, some ofthe proceeds of British purchase:; of south Russian wheat were transferred to Turkey and the Near East by a triangular trade mechanism, and it was these areas which were becoming increasingly important markets for British textiles in the I 840~s. But equally in question is the intelligence of some modern historians in failing to realize that conditions could change and that free trade arguments which were valid in a later period did not necessarily make nonsense of apparently conflicting reports about conditions in a earlier period. In the second place, British ships, which virtually had to carry the cargoes under the Navigation Acts from countries like Russia with no navy, were scarce at the best of times in the Black Sea and other grain ports, and their freights soared wildlly on the slightest expectation of grain price rises.

    The Nineteenth-Century Corn Law Reconsidered · 1965 · DOI

  • It addresses a specific methodological problem: outcome data for pioneer plants is dispersed, and failure is systematically under-reported relative to success.

    Pioneer Plant Risk Index (PPRI): a source-resolution protocol for first-of-a-kind plant performance databases · 2026 · DOI

  • The rollout of practices in countries facing policy lags within transition economies and their applicability under shocks also warrants attention (Incaltarau et al.

    Agricultural Decoupling in EU Transition Economies: Evidence from Tapio Elasticity Analysis · 2026 · DOI

  • However, this figure does not necessarily represent that farmers are economically prosperous, as the surplus (profit/income) between farming revenue and farming costs often remains insufficient compared to the poverty line.

    The Progressivity of Farmers’ Terms of Trade in Accelerating Fiscal Policy for Poverty Alleviation Programs in Gorontalo Province · 2026 · DOI

  • Conclusion and Suggestions Agricultural subsidies are essential for sustaining farming in Pattiam Grama Panchayat, but efficacy is limited by administrative constraints.

    Agricultural Input Subsidies: Awareness, Access, and Effectiveness · 2026 · DOI

  • While low farm incomes and restrictive environmental regulations are commonly cited grievances, little is known about underlying motivations and individual farmers’ reasons for protesting.

    Farmers’ Voices in European Protests: Diverse Complaints, Emotional Tones, and Policy Responses · 2025 · DOI

  • Previous literature has primarily addressed on-farm biodiversity and its effects on productivity and risk mitigation, yet the potential externalities of agrobiodiversity across neighboring farms remain underexplored.

    What is the value of agrobiodiversity in southern Europe? · 2024 · DOI

  • Agricultural informatization is regarded as a useful instrument for reducing carbon emissions, but few studies are devoted to illustrating the real effects and mechanisms of it in detail.

    Effects of agricultural informatization on agricultural carbon emissions: a quasi natural experiment study in China · 2024 · DOI

  • Many member states have set organic area targets through the initiation of organic action plans, but systematic, quantitative, empirical research into the effectiveness of such organic policies is lacking.

    National organic action plans and organic farmland area growth in Europe · 2023 · DOI

  • However, little is known about the extent to which observed land use change in the United States can be attributed to ethanol plant proximity or is caused by changes in crop prices that may be partly induced by expansion in ethanol production.

    Effects of Ethanol Plant Proximity and Crop Prices on Land‐Use Change in the United States · 2018 · DOI

  • However there is no standard definition of diversification from the point of agricultural economics aspect both traditional approaches and the influence of European Union should also be considered to define it.

    Extent and characteristic of diversification among Hungarian agricultural holdings · 2016 · DOI

  • Thus, public regulation is needed, but both theoretical background for achievement of the desirable result and rational measures of economical policy are lacking.

    Regulation of agricultural public goods provision on the basis of economic value · 2010

  • Current estimates of agricultural growth multipliers within rural regions vary widely, not only because economic structures differ across regions but also because the array of fixed‐price models most commonly used embody widely differing basic assumptions.

    Modeling Agricultural Growth Multipliers · 1991 · DOI

  • In each of the three areas cotton remains a significant source of farm income, while the importance of tobacco and peanuts varies widely from one area to another (Table 1).

    Federal Crop Allotment Programs and Responses by Individual Farm Operators · 1970 · DOI

  • The weakness of the original statement of the two-sted flow is that it did not account for differences in com- munication sources on the basis of stage in the adoption process.

    RESEARCH ON THE DIFFUSION OF AGRICULTURAL INNOVATIONS IN THE UNITED STATES AND THE NETHERLANDS · 1963 · DOI

  • Such tests of this new hypothesis as we were able to make indicated that it did not seem to fit the facts and we concluded that a theory of the pig-cycle is still lacking .
