This paper develops an equilibrium model of proof-of-work cryptocurrencies. Equilibrium behaviour of miners and users are characterized for exogenous blockchain protocol metrics. This paper shows that an equilibrium can be achieved in the long run. High fixed mining reward is the reason of instability in current cryptocurrency designs. The equilibrium model has two main implications. First, decentralization and technological improvement in mining are the drivers of low transaction fees and low mining costs. Second, limited block size and mining difficulty, which is endogenously determined, create an incentive mechanism that achieves the sustainability of cryptocurrency in the long run.
本文建立了一个工作量证明加密货币的均衡模型。矿工和用户的平衡行为以外生区块链协议指标为特征。本文表明,从长期来看,可以达到一种均衡。高固定挖矿奖励是当前加密货币设计不稳定的原因。均衡模型有两个主要含义。首先,采矿的权力下放和技术改进是低交易费和低采矿成本的驱动因素。其次,有限的区块大小和挖矿难度是内生决定的,创造了一种激励机制,实现了加密货币的长期可持续性。

Since independent, India has adopted cautious approach for economic growth but after the implementation of LPG policy (economic reforms in 1991) India has liberalized its foreign policy and took series of measures to pull FDI. This paper aimed to investigate empirically the impact of GDP, population, import of crude oil and corruption perception index on FDI over the last 20 years i.e. 1998-2018 The multiple regression tests were used in order to analyze the causal relationship among corruption perception index, import of crude oil, GDP and increasing rate of population. It was found that there is significant relationship between FDI, and GDP import of crude oil, corruption perception index and population.
自独立以来,印度一直采取谨慎的经济增长方式,但在实施液化石油气政策(1991年经济改革)后,印度放宽了外交政策,并采取了一系列措施来吸引外国直接投资。本文旨在实证考察1998-2018年近20年GDP、人口、原油进口和腐败感知指数对FDI的影响,采用多元回归检验分析腐败感知指数、原油进口、GDP和人口增长率之间的因果关系。研究发现,FDI与国内生产总值、原油进口、腐败感知指数和人口之间存在显著的相关关系。

Liberalizing, State Building, and Getting to Denmark: Analyzing Twenty-First Century Institutional Change 自由化、国家建设和走向丹麦:分析21世纪的制度变迁

This paper undertakes a descriptive analysis of changes in economic institutions across countries from 2000-2016, using Economic Freedom of the World and the “State Economic Modernity” index. This latter index is a recent creation, similar conceptually to state capacity, measuring what can variously be thought of as state building, effectiveness, and economic power. State Economic Modernity can also be thought of as the economic institutions associated with social democracy. These two indexes are used in concert with one another to classify countries into eight directions of institutional change. Despite recent pessimism, countries besides those at the top income bracket have continued to liberalize, while wealthy countries have merely stagnated. At the high level aggregates, there is little movement in “State Economic Modernity” over this period, although there is considerably heterogeneity among individual countries. Rwanda is the single country to make the greatest movement towards the development benchmark of “Getting to Denmark,” while, directionally, Democratic Republic of the Congo, Benin, Guinea-Bissau, and Indonesia have made significant positive movements as well.
本文利用世界经济自由度指数和“国家经济现代性”指数,对2000-2016年各国经济制度的变化进行了描述性分析。后一项指标是最近才出现的,在概念上与国家能力类似,衡量的是国家建设、效率和经济实力的不同方面。国家经济现代性也可以被认为是与社会民主主义相关的经济制度。这两个指标相互配合使用,将国家划分为制度变迁的八个方向。尽管最近出现了悲观情绪,但除高收入国家外,其他国家继续实行自由化,而富裕国家则停滞不前。在高水平上,“国家经济现代性”在这一时期几乎没有变化,尽管个别国家之间存在相当大的异质性。卢旺达是唯一一个朝着“走向丹麦”的发展基准迈出最大步伐的国家,而在方向上,刚果民主共和国、贝宁、几内亚比绍和印度尼西亚也取得了重大的积极进展。

The Political Prioritisation of Welfare in India: Comparing the Public Distribution System in Chhattisgarh and Jharkhand 印度福利的政治优先化:比较恰蒂斯加尔邦和贾坎德邦的公共分配制度

The idea of state responsibility for ensuring food security has gained ground, with strong popular mobilisations for the Right to Food around the world; but important variations prevail, both in the articulation of demands around food security interventions and in political responses to these. This paper takes a close look at India’s Public Distribution System, a programme with a long history and clear national-level, legislative backing, but considerable differences in prioritisation at the subnational level. Through an empirically rich and innovative comparison of Chhattisgarh with Jharkhand – both created at the same time, in 2000 – it asks why the opportunities afforded by statehood allowed Chhattisgarh to politically prioritise the PDS, but not Jharkhand. The paper finds that the explanation lies in the interrelated dimensions of political competition, the nature of pressures exerted by electorally significant societal groups, and political enablement of bureaucratic capacity. Finally, the analytical framework at the heart of the paper contributes to the emerging literature on the political conditions that allow the deployment of state capacity for the promotion of welfare.
国家对确保粮食安全负责的理念已经深入人心,世界各地都在大力动员民众争取食物权;但是,无论是在对粮食安全干预措施的要求表达方面,还是在对这些要求的政治回应方面,都存在着重要的差异。本文仔细研究了印度的公共分配系统,这是一个有着悠久历史和明确的国家级立法支持的项目,但在次国家一级的优先级上存在相当大的差异。通过对恰蒂斯加尔邦和贾坎德邦(两者都是在2000年同时创建的)进行丰富的经验和创新的比较,它提出了一个问题:为什么邦地位提供的机会允许恰蒂斯加尔邦在政治上优先考虑民主党,而贾坎德邦却没有。本文发现,解释在于政治竞争的相互关联维度,选举重要社会群体施加压力的性质,以及官僚能力的政治使能。最后,本文核心的分析框架有助于新兴的关于允许部署国家能力以促进福利的政治条件的文献。

Decomposition of Income Gaps Across Socioeconomic Groups: The Case of Six Asian Countries 社会经济群体收入差距的分解:以六个亚洲国家为例

This study applies unconditional quantile regressions estimated using recentered influence functions to analyze income gaps based on households’ residence, education and employment status in six Asian countries. China, India, Japan, Korea, Russia and Taiwan are found to represent different demographic corners of Asia and different stages of development. Rural/urban gaps exist across all six countries, particularly China, India and Russia, but have been falling in Russia. Rural households face mobility barriers and lack decent employment opportunities, thus lacking incentives for skill investment. Gaps between less/more educated households are also prevalent. Less educated households tend to be rural and face low returns on their other marketable characteristics. In China and India, gaps by employment status surprisingly favor households with non-employed heads. In India, a non-working class of rural rich live off saved wealth or remittances from urban professionals. In China, a class of rural poor appear to live off remittances from migrant laborers. We conclude that Asian emerging economies should strengthen their rural assistance programs, and lower the mobility and resettlement barriers, to improve rural households’ access to education and employment.
本研究采用重中心影响函数估计的无条件分位数回归,分析了六个亚洲国家基于家庭居住、教育和就业状况的收入差距。中国、印度、日本、韩国、俄罗斯和台湾代表着亚洲不同的人口角落和不同的发展阶段。城乡差距在所有六个国家都存在,尤其是中国、印度和俄罗斯,但在俄罗斯一直在缩小。农村家庭面临流动性障碍,缺乏体面的就业机会,因此缺乏技能投资的激励。受教育程度较低和较高的家庭之间的差距也很普遍。受教育程度较低的家庭往往是农村家庭,他们在其他市场特征上面临低回报。在中国和印度,就业状况差距令人惊讶地有利于户主没有工作的家庭。在印度,非工人阶级的农村富人靠储蓄或城市专业人士的汇款生活。在中国,农村贫困阶层似乎靠农民工的汇款生活。我们的结论是,亚洲新兴经济体应加强其农村援助计划,降低流动和安置障碍,以改善农村家庭获得教育和就业的机会。

Shedding Light on Regional Growth and Convergence in India 揭示印度的区域增长和趋同
Pub Date : 2018-12-01 DOI: 10.2139/ssrn.3308685
A. Chanda, S. Kabiraj
Abstract A large body of research on India’s rapid economic growth since 1991 also documents increasing regional disparities. In this paper, we use unsaturated night light data to challenge this dominant narrative of unequal growth. For 520 districts spanning a 15 year period (1996–2010), we find overwhelming evidence of absolute convergence. Dividing districts further into rural and urban areas, we also show that this catching-up can be attributed mainly to faster growth in rural areas. Geographically disadvantaged districts - those further away from the coast, with lower agricultural suitability, and more rugged terrain also grew faster. The convergence results are not associated with major infrastructure and education initiatives that overlapped with the period of analysis, and also hold for alternative measures of night-lights that cover a longer period of time (1992–2013).
自1991年以来,大量关于印度经济快速增长的研究也证明了地区差距的扩大。在本文中,我们使用不饱和的夜间灯光数据来挑战这种不平等增长的主导叙述。在横跨15 年(1996-2010)的520个地区中,我们发现了绝对趋同的压倒性证据。将地区进一步划分为农村和城市地区,我们还表明,这种追赶主要归因于农村地区的更快增长。离海岸较远、农业适宜性较低、地形崎岖的地理条件较差的地区也增长较快。趋同结果与分析期间重叠的主要基础设施和教育举措无关,也适用于覆盖较长时间(1992-2013)的夜灯替代措施。

Housing, Homelessness and Poverty 住房、无家可归和贫困
Pub Date : 2018-11-01 DOI: 10.11575/SPPP.V11I0.43293
Ronald Kneebone
In 2014, an estimated 137,000 people, or about one in 208 Canadians aged 18 or older, stayed in an emergency homeless shelter. While addictions and mental illness can contribute to homelessness, evidence suggests that the majority of people who resort to using homeless shelters do so because they are poor. Public policies that reduce the cost of housing for those with low income would reduce these numbers and reduce the number of Canadians who annually experience the debilitating effects of homelessness. A high proportion of rent-to-income is a key contributor to homelessness. People who find that rent eats up so much of their income that they can’t afford other necessities will often try their luck doubling up with relatives or friends or temporarily using a city’s shelter system. Anything that influences the rent-to-income ratio – from income support programs, to tax policies affecting the costs of new construction and the costs of maintaining or rehabilitating old buildings, to zoning and density restrictions – will therefore have a significant influence on the rate of homelessness. Recognizing this opens a wide range of policy options and exposes all levels of government to the responsibility for initiating useful policy reforms. Modest efforts to increase housing affordability via rent subsidies and enhanced income support have the advantage over the construction of public housing of maximizing choice and flexibility for those to whom assistance is provided. If the great majority of people experiencing homelessness do so because of poverty, it may be best to address that issue directly with increased levels of income support.
2014年,估计有13.7万人,即每208名18岁及以上的加拿大人中就有一人住在紧急无家可归者收容所。虽然成瘾和精神疾病可能导致无家可归,但有证据表明,大多数求助于无家可归者收容所的人是因为他们很穷。降低低收入者住房成本的公共政策将减少这些数字,减少每年因无家可归而衰弱的加拿大人的数量。房租与收入之比过高是导致无家可归的一个关键因素。那些发现房租占了收入的很大一部分,以至于买不起其他必需品的人,往往会碰碰运气,与亲戚朋友合租,或者暂时使用城市的住房系统。因此,任何影响租金收入比的因素——从收入支持计划,到影响新建筑成本和维护或修复旧建筑成本的税收政策,再到分区和密度限制——都将对无家可归率产生重大影响。认识到这一点,就有了广泛的政策选择,并使各级政府有责任发起有益的政策改革。通过租金补贴和增加收入支助来提高住房负担能力的适度努力,比建造公共住房的优势在于为获得援助的人提供最大限度的选择和灵活性。如果绝大多数无家可归的人是因为贫穷而无家可归,那么最好通过增加收入支持水平来直接解决这个问题。

ICTs in Agricultural Practices: Hopes, Utopias and Contradictions 农业实践中的信息通信技术:希望、乌托邦和矛盾
Pub Date : 2018-10-30 DOI: 10.2139/ssrn.3275129

The findings from some research studies conducted to ascertain the factors affecting the adoption of Information and Communication technologies for farming decisions suggest that the ICTs might just live up to the expectation of being the harbinger of agricultural growth and better life chances for rural farmers. In the given study, through a series of interviews conducted in the given setting, I have tried to map how ICT resources are perceived in a setting where there is no targeted privately or state run ICT initiative. The case of initiatives which involve deployment of ICTs in monitored settings like the Gyandoot project, run in Dhar by the government of the state of Madhya Pradesh in India or the E-choupal Project run by Indian Tobacco Company (ITC), again in Dhar, has been elaborated upon in various studies. In monitored projects, usually a specific crop is targeted (for example soybean in case of e-choupals). Here, ICTs are used to assist specialized supply chain management. However, in the case of my study, I have tried to look at the penetration of ICTs in the workflow of a sample of farmers, selected randomly from a given village located in one of the districts, in the state of eastern Uttar Pradesh, India. The rationale for the sampling is to assess the diffusion, penetration and implementation of ICTs and the spillover effects (if any) of the telecommunication revolution in India. Agriculture extension and information dissemination in India is governed by the agricultural extension arm of the Indian Council of Agricultural Research is referred to as ‘Krishi Vigyan Kendras’. These centers dispense extension services at the district level and are managed by the State Agricultural Universities. The Krishi Vigyan Kendra in Gorakhpur is affiliated to Acharya Narendra Dev Agricultural University, Faizabad district and is situated at Belipar, Gorakhpur. Through my study, I have tried to study the role of ICT tools such as mobile phones, radios and television in assisting the district level extension services.
为确定影响在农业决策中采用信息通信技术的因素而进行的一些研究的结果表明,信息通信技术可能正好符合人们对农业增长和农村农民更好生活机会的预期。在给定的研究中,通过在给定环境中进行的一系列访谈,我试图绘制出在没有针对性的私营或国有ICT倡议的环境中如何感知ICT资源。诸如印度中央邦政府在达尔实施的Gyandoot计划,或印度烟草公司(ITC)在达尔实施的E-choupal计划等,在受监控的环境中部署ict的案例,已在各种研究中得到详细阐述。在受监测的项目中,通常以特定作物为目标(例如,e-choupals项目中的大豆)。在这里,信息通信技术被用来协助专门的供应链管理。然而,在我的研究中,我试图观察信息通信技术在农民工作流程中的渗透情况,这些农民是从印度北方邦东部一个地区的一个特定村庄随机挑选出来的。抽样的基本原理是评估信息通信技术的扩散、渗透和实施情况,以及印度电信革命的溢出效应(如果有的话)。印度的农业推广和信息传播由印度农业研究委员会的农业推广部门管理,该部门被称为“Krishi Vigyan Kendras”。这些中心在地区一级提供推广服务,并由国立农业大学管理。Gorakhpur的Krishi Vigyan Kendra隶属于Faizabad地区的Acharya Narendra Dev农业大学,位于Gorakhpur的Belipar。通过我的学习,我试图研究信息通信技术工具,如移动电话,收音机和电视在协助地区层面的推广服务中的作用。

China’s food security has increasingly been one worldwide concern. And, most researchers argue that land transfer further aggravates the problem of non-grain in rural China. We theoretically pursue the the internal mechanism of the effects of land rental on the grain production and then employ 2,088 household survey data collected in China to assess their relationship. The estimated results indicate that land rental positively affects grain production, especially with the decrease of agricultural labor. Contrarily, land rental has significantly negative impact on grain production with the increase of agricultural labor. Besides, we also find that the reason that land rental stimulates grain production is that the grain production can be more easily mechanized than that of cash crops in rural China, which is conductive to reducing the high labor cost in agriculture and encouraging off-farm employment. Thus, when considering the development of mechanization in grain production and high labor cost in agriculture, grain production has been the voluntary choice of the land leaseholders, and this undoubtedly ensures China’s grain security.
中国的粮食安全日益成为世界关注的焦点。大多数研究者认为,土地流转进一步加剧了中国农村的非粮食问题。本文从理论上探讨了土地租赁对粮食生产影响的内在机制,并利用在中国收集的2088个农户调查数据来评估二者之间的关系。估算结果表明,土地租金对粮食生产有正向影响,特别是随着农业劳动力的减少。相反,随着农业劳动力的增加,土地租赁对粮食生产的影响呈显著负向。此外,我们还发现土地租赁刺激粮食生产的原因是中国农村粮食生产比经济作物生产更容易机械化,这有利于降低农业高劳动力成本,鼓励非农就业。因此,考虑到粮食生产机械化的发展和农业较高的劳动力成本,粮食生产已经成为土地承租人的自愿选择,这无疑保证了中国的粮食安全。
