The literature on data and economic rights is not vast. This is primarily because rights advocates and researchers have paid more attention to the relationship between data and privacy than between data and economic rights. In this paper we review the literature that is available with an inevitable over-reliance of certain contributions because of the paucity of directly relevant literature. We choose to focus on the application of data rights in the agricultural sector because of both the perceived value of data to farmers and, in the case of the majority of farmers in developing countries, their vulnerable position in relation to other actors in the system.
有关数据和经济权利的文献并不多。这主要是因为权利倡导者和研究人员更关注数据与隐私的关系,而不是数据与经济权利的关系。在本文中,我们回顾了由于直接相关文献的缺乏而不可避免地过度依赖某些贡献的文献。我们之所以选择关注数据权利在农业部门的应用,是因为数据对农民的感知价值,以及在发展中国家的大多数农民的情况下,他们与系统中其他参与者相比处于弱势地位。

Liquidity Windfalls and Reallocation: Evidence from Farming and Fracking 流动性意外之财和再分配:来自农业和水力压裂的证据

Financing frictions may create a misallocation of assets in a market, thus depressing output, productivity, and asset values. This paper empirically explores how liquidity shocks generate a reallocation that diminishes this misallocation. Using a unique data set of agricultural outcomes, I explore how farmers respond to a relaxation of financial constraints through a liquidity shock unrelated to farming fundamentals, namely exogenous cash inflows caused by an expansion of hydraulic fracturing (fracking) leases. Farmers experiencing positive cash flow shocks increase their land purchases, which results in a reallocation effect. Examining purchases across areas, I find that farmers in high-productivity areas who receive cash flow shocks buy farmland in low-productivity areas, but farmers in low-productivity areas receiving positive cash flow shocks do not. Moreover, farmers increase their purchases of vacant (undeveloped) land. Average output, productivity, equipment investment, and profits all increase significantly following these positive cash flow shocks. Farmland prices also rise significantly, consistent with a cash-in-the-market pricing effect. These effects are consistent with an efficient reallocation of land toward more productive users.

融资摩擦可能造成市场上资产的错配,从而抑制产出、生产率和资产价值。本文从实证角度探讨了流动性冲击如何产生减少这种错配的再配置。利用一组独特的农业结果数据,我探讨了农民如何通过与农业基本面无关的流动性冲击来应对金融约束的放松,即由水力压裂(水力压裂)租赁扩张引起的外源性现金流入。经历正现金流冲击的农民增加了土地购买,这导致了再分配效应。通过考察不同地区的购买情况,我发现在高生产率地区受到现金流冲击的农民会购买低生产率地区的农田,而在低生产率地区受到正现金流冲击的农民则不会购买。此外,农民增加了对空置(未开发)土地的购买。在这些正现金流冲击之后,平均产出、生产率、设备投资和利润都显著增加。农田价格也大幅上涨,与市场现金定价效应一致。这些影响与有效地将土地重新分配给生产力更高的用户是一致的。这篇论文被财经的泰勒·沙姆威接受了。资助:本研究由Kritzman and Gorman研究基金资助。补充材料:在线附录可在https://doi.org/10.1287/mnsc.2022.4602上获得。

The contemporary agriculture is among the most risky economic activities. In addition to the previously known production, price and market risk, and later also the financial risk, today agricultural producers are increasingly more often confronted with institutional risk and personnel management risk and risk related to climate change. On the other hand, farmers have at their disposal numerous tools and strategies to counteract threats and mitigate their negative effects. Among these risk management instruments and strategies, traditional/ conventional insurance of crops, livestock and tangible assets is still important. In this context, the basic goal of the article is to generalise the theoretical foundations of the above-mentioned insurance, but limited to their historically oldest approach; hence on the basis of neoclassical microeconomics and classical decision theory. According to the convention existing, the essence of the theory/hypothesis of the expected utility of von Neumann–Morgenstern is first analysed. In the last part of the article, the assumptions of the expected utility theory are concretised on the example of agricultural insurance.
现代农业是风险最大的经济活动之一。除了以前已知的生产、价格和市场风险,以及后来的金融风险,今天的农业生产者越来越多地面临制度风险和人员管理风险以及与气候变化相关的风险。另一方面,农民可以使用许多工具和策略来抵消威胁并减轻其负面影响。在这些风险管理工具和战略中,作物、牲畜和有形资产的传统/传统保险仍然很重要。在此背景下,本文的基本目标是概括上述保险的理论基础,但仅限于其历史上最古老的方法;因此在新古典微观经济学和古典决策理论的基础上。根据已有的惯例,首先分析了冯·诺伊曼-摩根斯坦期望效用理论/假设的本质。文章最后以农业保险为例,对期望效用理论的假设进行了具体说明。

Determinants of Household's Modern Cooking and Lighting Energy Transition in Rural India- Exploring Household's Activities and Its Interactions with Other Households 印度农村家庭现代烹饪和照明能源转型的决定因素——探索家庭活动及其与其他家庭的互动
Pub Date : 2018-03-01 DOI: 10.2139/ssrn.3161908
The majority of rural Indian households remain dependent on unreliable, inefficient and harmful household energy technologies. Rural households make their energy decisions with respect to the Water-Energy-Food security (WEF) Nexus jointly, however, previous research initiatives have analyzed household energy access problem in isolation. By analyzing household’s activities and its interactions with other households, this paper identified the factors that impact household’s transition to modern energies of different kinds. For the analysis, it utilized logit and zoib (zero-one-inflated beta) regression techniques on the household survey data set from the Uttar Pradesh province of India. The results showed that regular non-agricultural income of household’s male member increases the probability of household’s modern cooking energy and modern lighting transition by 8.6% and 13.6%, respectively. It was found that household’s higher agricultural dependence and resource endowments (more labor and cattle) lead to higher share of traditional bioenergy consumption in the total cooking energy mix. Proximity to markets and high household income were observed to positively influence household modern cooking and lighting transition. Local institutions such as local bio-energy markets and barter trade for labor- bioenergy was observed to have significant influence on household energy choice. Results also showed that government’s policy instrument such as household connection to government LPG scheme is associated with 20.5% increased probability of household using modern cooking energy as its primary cooking fuel. Results also indicated that social factors such as higher female education and young age of household head are associated with household’s increased modern cooking energy consumption in its total cooking energy mix.
大多数印度农村家庭仍然依赖不可靠、低效和有害的家庭能源技术。农村家庭根据水-能源-粮食安全Nexus共同作出能源决策,然而,以前的研究举措孤立地分析了家庭能源获取问题。本文通过对家庭活动及其与其他家庭的互动分析,确定了影响家庭向不同类型现代能源过渡的因素。为了进行分析,它对印度北方邦的家庭调查数据集使用了logit和zoib(零-一膨胀beta)回归技术。结果表明,家庭男性成员的经常性非农业收入使家庭向现代烹饪能源和现代照明转型的概率分别提高8.6%和13.6%。研究发现,家庭对农业的依赖程度和资源禀赋(劳动力和牲畜)越高,传统生物能源消费在烹饪总能源结构中的比例越高。接近市场和高家庭收入被观察到积极影响家庭现代烹饪和照明过渡。当地生物能源市场和劳动生物能源易货贸易等地方制度对家庭能源选择有显著影响。结果还显示,政府的政策工具,如家庭连接到政府液化石油气计划,与家庭使用现代烹饪能源作为主要烹饪燃料的可能性增加20.5%有关。研究结果还表明,女性受教育程度高、户主年龄小等社会因素与家庭现代烹饪能源消耗在总烹饪能源结构中的增加有关。

Youths can make their constructive contribution to national development and through which society can benefit from the idealism and the sense of dedication of youth at the same time, they also get benefitted from their active participation in development activities, since such participation increases their self esteem, gives them a sense of identity. India has rich rural youth potential. The population of rural youth in developmental activities contribute to national development. Several studies confirm that there exist shifting patterns in the occupation of rural youth from agriculture to other nonfarm activities. A study was taken up “To measure the impact of the shift from agriculture to other nonfarm occupation in Coimbatore district of Tamil Nadu”. Hence, in this study an analysis was made in Coimbatore district of Tamil Nadu with 120 sample rural youth respondents. Nearly 80.83 per cent of the rural youth expressed that there is no much difference in the purchasing power due to shifting and their property acquisition also has slightly increased and 76.66 per cent expressed that there is no much change was observed.
青年可以对国家发展作出建设性的贡献,社会可以从青年的理想主义和奉献精神中受益,同时,他们也从积极参与发展活动中受益,因为这种参与增加了他们的自尊,给了他们一种认同感。印度拥有丰富的农村青年潜力。农村青年人口在发展活动中对国家发展作出贡献。一些研究证实,农村青年的职业存在着从农业到其他非农活动的转移模式。进行了一项研究,“衡量泰米尔纳德邦哥印拜陀地区从农业转向其他非农业职业的影响”。因此,在本研究中,对泰米尔纳德邦哥印拜陀地区的120名农村青年样本进行了分析。近80.83%的农村青年表示,由于转移,购买力没有太大变化,他们的房产购置也略有增加,76.66%的农村青年表示没有太大变化。

E quale ruolo giocano in questo quadro evolutivo le organizzazioni dell’economia sociale e solidale che tradizionalmente hanno svolto un ruolo pionieristico a livello di advocacy e di innovazione di prodotto e processo? English Abstract: This paper aims at reframing the “critical” statute of consumption, delving into the models that from unconventional have become mainstream. In particular, the focus of the analysis is on the effects produced by the new value chains, which feature a more informed/proactive consumer. More specifically, the authors argue whether traditional markets are reshaping their productive processes and governance models to answer the “social” needs of their target publics. Moreover, they investigate the role of social and solidarity economy organizations in this evolving framework, highlighting their pioneering function and their advocacy role in product and process innovation.

Rural Shadow Wages and Youth Agricultural Labor Supply in Ethiopia: Evidence from Farm Panel Data 埃塞俄比亚农村影子工资与青年农业劳动力供给:来自农场面板数据的证据

The majority of the youth in Ethiopia live in rural areas where agriculture is the main source of livelihood. Using gender- and age-specific values of agricultural labor return (shadow wages), we systematically analyse trends, patterns and prospects of youth’s labor supply in agriculture across space (farm locations). We also analyse whether the household male and female youth members’ agricultural labor supply is responsive to economic incentives. We investigate these using shadow wages estimation techniques applied to farm-household panel data collected during the 2010/11 and 2014/15 agricultural seasons. The results indicate that trends and patterns of the youth’s involvement in agriculture vary across gender and farm work locations, and so do their labor returns. Yet the on-farm participation for youth members is declining across time irrespective of gender, whilst their participation in off-farm activities is increasing. The findings also suggest that changes in agricultural shadow wages matter for the youth’s involvement in the sector, but their impact differs for male and female youth. The results are consistent after controlling for individual heterogeneity, sample selection and instrumenting for possible endogeneity. In addition, we find that youth’s intentions and actual engagement in agricultural production vary greatly. This suggests that the frequent narrative of youth disengaging from agriculture may be a result of methodological flaws or data limitations. Taking into account the intensity of the youth’s involvement in family farm, own farm and off-farm work, the results challenge the presumption that youth are abandoning agriculture, at least in agricultural potential areas of Ethiopia. Instead the youth’s involvement makes an important economic contribution to the operation of the family farm. Therefore, it is necessary to invest in agricultural development to enhance productivity and employment opportunities; and structural transformation that addresses the imperfections and rigidities in labor and other input markets to make agriculture more attractive to youth.
埃塞俄比亚的大多数青年生活在农村地区,农业是那里的主要生计来源。利用特定性别和年龄的农业劳动力回报值(影子工资),我们系统地分析了跨空间(农场地点)青年农业劳动力供应的趋势、模式和前景。我们也分析家庭是否男女青年成员的农业劳动力供给是经济激励响应。我们使用影子工资估算技术对2010/11和2014/15农业季节收集的农户面板数据进行了研究。结果表明,趋势和模式的青年参与农业不同性别和农场的工作地点,所以他们劳动的回报。然而,无论性别如何,青年成员的农场参与率都在下降,而他们参与非农活动的人数却在增加。研究结果还表明,农业影子工资的变化对青年参与该部门有影响,但其对男性和女性青年的影响不同。在控制了个体异质性、样本选择和可能的内生性仪器之后,结果是一致的。此外,我们发现青年参与农业生产的意愿和实际参与程度差异很大。这表明,青年脱离农业的频繁叙述可能是方法缺陷或数据限制的结果。考虑到青年参与家庭农场、自有农场和非农业工作的强度,结果挑战了年轻人正在放弃农业的假设,至少在埃塞俄比亚的农业潜力地区是这样。相反,青年的参与对家庭农场的经营做出了重要的经济贡献。因此,有必要投资农业发展,以提高生产力和就业机会;结构转型,解决劳动力和其他投入市场的不完善和僵化问题,使农业对年轻人更具吸引力。

The aim of this study is to determine the effect of backflush accounting on financial performance with particular referenceto food and beverage firms. This study therefore, examines the effect of Backflush accountingon financial performanceof food and beverage firms quoted on Nigeria Stock Exchange from 2010 to 31stDecember 2015. The research designemployed in this study is the ex-post facto research. An ex-post facto research determines the cause-effect relationshipamong variables. Only secondary data was used in this study. Three hypotheses were formulated and tested in the courseof this study. The Statistical tools used to test the hypotheses were coefficient of correlation and ordinary least squareregressionwith the aid of STATA 13 statistical software. The study revealed that backflush accounting has a positive andstatistically significant effect on ROA, ROE, and EPS of food and beverage firms quoted on the floor of Nigerian StockExchange at 5% level of significance. The researchers recommend among others that manufacturing firms should try toenforce the use of emerging new trends in management accounting practice even though it might not be cost effective interms of staff training and cost of acquiring the technology, but the benefits outweighs the costs in the long run.
本研究的目的是确定反冲会计对财务绩效的影响,特别是参考食品和饮料公司。因此,本研究考察了反冲会计对2010年至2015年12月31日在尼日利亚证券交易所上市的食品和饮料公司财务绩效的影响。本研究采用的是事后研究。事后研究确定了变量之间的因果关系。本研究仅使用了二手数据。在本研究的过程中,提出了三个假设并进行了测试。检验假设的统计工具为相关系数法和普通最小二乘回归法,采用stata13统计软件。研究发现,倒冲会计对尼日利亚证券交易所场内上市的食品和饮料公司的ROA、ROE和EPS具有正的统计学显著影响,显著性水平为5%。研究人员建议,制造企业应该尝试在管理会计实践中强制使用新兴的新趋势,尽管从员工培训和获取技术的成本来看,这可能不具有成本效益,但从长远来看,收益大于成本。

The present study, carried out in the state of Maharashtra during 2004-05, focuses on two cases of multipurpose cooperatives dealing mainly with the marketing of fruits but having their spectrum spread over various other marketing activities, including input and credit delivery. The synthesis of case studies shows multifarious reasons for their inefficient functioning and important among them revolve around lack of transport facility and trained staff, inefficient management, interference of private traders, excessive commission, repayment of loan, default rate, interest rate structure, attitude of private traders, lack of dedicated leadership, diversion of poor quality of produce by members, shortfall in procurement, etc. In fact, both the societies have shown poor grasp either in terms of studying the market forces or shown inefficiency because of their own internal drawbacks in terms of managing the societies or their own personal interests involved in the functioning of the society. The societies are unable to generate allies for lobbing to safeguard as well as promoting their own interests and the interests of their members. Since the existence of internal interest-cum-entrepreneurial group in providing a dedicated and efficient management stands very low, as the members of the board are reported to be self-centered with lack of motivation in terms of growth of the society, there has been adverse impact on the working of these societies. Further, because of lack of funds and losses incurred by the societies coupled with self-interests of the leaders, the member farmers are now diverting their produce to other private traders. This certainly has some adverse implications insofar as the functioning of these societies even in future is concerned. However, it is suggested that efforts should be made to rectify the deficiencies in the functioning of these cooperative societies dealing with the marketing of high value crops. Some remedial measures and strategies framed or initiated by these marketing societies, particularly in respect of recovery of their loan advances, will certainly improve their efficiency and functioning in future. Government support in this respect will have a catalytic effect in improving the overall efficacy and efficiency, as well as functioning, of various Primary Cooperative Marketing Societies (PCMS) operating in Maharashtra.
本研究于2004- 2005年在马哈拉施特拉邦进行,重点研究了两个多用途合作社的案例,这些合作社主要从事水果销售,但其业务范围遍及其他各种营销活动,包括投入和信贷交付。综合案例研究表明,它们的低效运作有多种原因,其中重要的原因包括缺乏运输设施和训练有素的工作人员、管理效率低下、私营贸易商的干预、佣金过高、偿还贷款、违约率、利率结构、私营贸易商的态度、缺乏专门的领导、成员转移劣质产品、采购不足等。事实上,这两个社会在研究市场力量方面都表现出不好的把握,或者表现出低效率,因为它们在管理社会方面或在社会运作中涉及到自己的个人利益方面存在内部缺陷。这些社团无法为维护和促进自身利益及其成员的利益而游说,从而产生盟友。由于内部利益-创业群体在提供专注和高效管理方面的存在性很低,据报道董事会成员以自我为中心,缺乏对社会成长的动力,这对这些社团的工作产生了不利影响。此外,由于缺乏资金和社团遭受的损失,再加上领导人的私利,成员农民现在将他们的产品转移给其他私人商人。就这些社会在未来的运作而言,这当然会产生一些不利的影响。但是,有人建议应作出努力,纠正这些合作社在销售高价值作物方面的运作缺陷。这些销售协会制定或发起的一些补救措施和战略,特别是在收回其贷款垫款方面,肯定会提高其今后的效率和运作。政府在这方面的支持将对提高在马哈拉施特拉邦运作的各种初级合作营销协会的总体功效和效率以及运作产生催化作用。

Price fluctuations in agricultural markets are an obstacle to poverty reduction for small-scale farmers in developing countries. We build a micro-foundation to study how farmers of heterogeneous production costs, under price fluctuations, make crop-planting decisions over time to maximize their incomes. We consider both strategic farmers, who rationally anticipate the near-future prices as a basis for making planting decisions, and naive farmers, who shortsightedly react to recent crop prices. The latter behavior may cause recurring over- or under-production, which leads to price fluctuations. We find it important to cultivate strategic farmers, because their self-interested behavior alone, made possible by sufficient market information, can reduce price volatility and benefit all farmers. Surprisingly, even a tiny number of strategic farmers may be enough to stabilize a market price. In the absence of strategic farmers, a well-designed pre-season procurement contract, offered by a non-profit or for-profit firm to a fraction of contract farmers, can bring benefit to all the farmers as well as to the firm itself and reduce income disparity among farmers. On the other hand, a poorly designed contract may distort the market and drive non-contract farmers out of business.
农业市场的价格波动是发展中国家小农减贫的一个障碍。我们建立了一个微观基础来研究在价格波动下,异质性生产成本的农民如何随着时间的推移做出作物种植决策以最大化他们的收入。我们考虑了战略型农民和天真型农民,前者理性地预测近期的价格,作为做出种植决定的基础,后者对近期的作物价格做出短视的反应。后一种行为可能导致生产过剩或生产不足,从而导致价格波动。我们发现培养有战略眼光的农民是很重要的,因为他们的自利行为,只要有足够的市场信息,就可以减少价格波动,使所有农民受益。令人惊讶的是,即使是少数具有战略意义的农民也足以稳定市场价格。在缺乏战略农民的情况下,由非营利性或营利性企业向一小部分合同农民提供一份设计良好的季前采购合同,可以为所有农民以及企业本身带来利益,并减少农民之间的收入差距。另一方面,设计不当的合同可能会扭曲市场,使无合同农民破产。
