Breaking the taboo: a history of monetary financing in Canada, 1930–1975

Monetary financing – the funding of state expenditure via the creation of new money rather than through taxation or borrowing – has become a taboo policy instrument in advanced economies. It is generally associated with dangerously high inflation and/or war. Relatedly, a key institutional feature of modern independent central banks is that they are not obligated to support government expenditure via money creation. Since the financial crisis of 2007–2008, however, unorthodox monetary policies, in particular quantitative easing, coupled with stagnant growth and high levels of public and private debt have led to questions over the monetary financing taboo. Debates on the topic have so far been mainly theoretical with little attention to the social and political dynamics of historical instances of monetary financing. This paper analyses one of the most significant twentieth‐century cases: Canada from the period after the Great Depression up until the monetarist revolution of the 1970s. The period was a successful one for the Canadian economy, with high growth and employment and manageable inflation. It offers some interesting insights into the relationship between states and central banks and present‐day discussions around the governance of money creation.     

Price-setting newsvendor with strategic consumers

We consider a newsvendor who sells a single product over a single season with the objective of determining both the selling price and stock quantity to maximize the expected profit. The customers are strategic and we consider two demand cases: additive and multiplicative. For each case, we derive the newsvendor׳s optimal decisions and demonstrate that neglecting the price-sensitivity of demand leads the newsvendor to make sub-optimal decisions. Moreover, we show that under certain conditions, strategic consumer behavior may positively affect the newsvendor׳s optimal expected profit in the additive demand case.     

贵州社会管理创新:经验、问题与出路

近年来,贵州社会管理创新取得了一些成效,其主要经验是强化中国共产党在社会管理创新中的领导地位,发挥政府在社会管理创新中的主导作用,创新内容要关注民生。尽管如此,贵州社会管理创新还存在社会矛盾化解机制不健全、基层政府社会管理力量薄弱、社会组织培育机制不健全等问题,应通过完善源头治理机制、改革基层社会管理体制、优化社会组织培育机制等途径来解决。     

中国地方NGO生成机制的制度分析

地方NGO作为一种具体制度安排，其生成机制主要是在外在制度环境的作用下，以潜在利益为基本诱因，外在制度需求与内在制度供给相互契合推进，从而激励地方公民合作创设NGO制度安排的复杂过程。这是中国地方NGO生成的简要逻辑。从制度需求与制度供给的视角分析，在中国地方NGO的生成机制中，国家与市场对NGO制度安排的供给、市民集体行动的理性选择、地方制度转型的适应性安排、地方政府之间的制度竞争、地方知识精英的主导性介入与网络等科学技术进步的推动是六个关键性因素。特别是国家与市场的博弈过程与中国地方NGO的发展壮大过程相伴相生。分析中国地方NGO的生成机制，可以窥见中国公民社会的生长与发展轨迹。     

启动农村消费的障碍及消除障碍的路径选择研究

消费是拉动内需,推动经济持续、健康发展的不懈动力,然而现阶段我国居民消费对GDP增长的促进作用较弱,尤其是农村消费,但由于受收入、物价、市场发达程度等因素的制约,农村消费长期以来一直被压制.采用定量、定性相结合的分析方法,通过构造数量模型分析影响消费的主要因素及影响程度,在此基础上重点对影响农村消费增长的原因进行分析,并提出相应的解决措施.     

A Theory of Macroprudential Policies in the Presence of Nominal Rigidities

We propose a theory of monetary policy and macroprudential interventions in financial markets. We focus on economies with nominal rigidities in goods and labor markets and subject to constraints on monetary policy, such as the zero lower bound or fixed exchange rates. We identify an aggregate demand externality that can be corrected by macroprudential interventions in financial markets. Ex post, the distribution of wealth across agents affects aggregate demand and output. Ex ante, however, these effects are not internalized in private financial decisions. We provide a simple formula for the required financial interventions that depends on a small number of measurable sufficient statistics. We also characterize optimal monetary policy. We extend our framework to incorporate pecuniary externalities, providing a unified approach to both externalities. Finally, we provide a number of applications which illustrate the relevance of our theory.     

Shadow Insurance

Life insurers use reinsurance to move liabilities from regulated and rated companies that sell policies to shadow reinsurers, which are less regulated and unrated off‐balance‐sheet entities within the same insurance group. U.S. life insurance and annuity liabilities ceded to shadow reinsurers grew from $11 billion in 2002 to $364 billion in 2012. Life insurers using shadow insurance, which capture half of the market share, ceded 25 cents of every dollar insured to shadow reinsurers in 2012, up from 2 cents in 2002. By relaxing capital requirements, shadow insurance could reduce the marginal cost of issuing policies and thereby improve retail market efficiency. However, shadow insurance could also reduce risk‐based capital and increase expected loss for the industry. We model and quantify these effects based on publicly available data and plausible assumptions.     

不确定环境下的Supply-hub协同补货决策

个性化需求与零部件创新使得产品需求和补货提前期不确定,对供应链补货决策和运行成本产生重要影响。将提前期不确定因素引入Supply-hub协同补货研究中,探讨提前期随机和需求不确定情况下,考虑零部件配套性的三供应商单制造商生产两定制产品的Supply-hub协同补货决策问题;提出了三种补货策略,以供应链运行成本最小化为目标,建立不同策略下的供应链补货模型并求解最优补货批量和供应链最小运行成本;发现三种补货策略均存在唯一最优补货批量,基于Supply-hub的两种协同补货策略和基于分散决策的供应商独立补货策略各有优势,但基于Supply-hub的批量及时间协同的补货策略恒优于基于Supply-hub的集中补货策略。最后,通过MATLAB进行算例分析验证结论,发现基于Supply-hub的批量及时间协同的补货策略能有效降低需求不确定性带来的成本增加风险;通用件的提前期波动对于供应链期望运行成本的影响要高于定制件提前期波动的影响,因此在进行供应链补货策略选择时更加关注通用件提前期。     

供需不确定条件下基于CVaR的零售商库存鲁棒优化模型

在经典报童模型下考虑供应和需求不确定性,研究了具有风险厌恶的零售商库存优化问题。采用条件风险值（CVaR）对库存绩效进行度量,构建了基于CVaR的零售商库存运作模型;在此基础上,考虑上游供应商供货能力和下游市场需求不确定性,并采用一系列未知概率的离散情景进行描述,给出了供需不确定条件下基于CVaR的零售商库存鲁棒优化模型。进一步,采用区间不确定集对未知情景概率进行建模,给出了基于最大最小准则的鲁棒对应模型。针对同时考虑供需不确定性导致的模型非凸性,采用标准对偶理论将其转化为易于求解的数学规划问题。最后,通过数值计算分析了不同风险厌恶程度和不确定性程度对零售商库存决策以及库存绩效的影响。结果表明,供需不确定性的存在虽然会导致零售商库存绩效损失,但损失值较小。特别地,依据文中模型得到的鲁棒库存策略在多数情况下能够保证零售商获得更优的库存绩效。此外,不确定性和风险厌恶程度的增加虽然会影响零售商库存决策和运作绩效,但在同等风险厌恶态度下,随着不确定性程度的增加,基于文中方法得到的鲁棒库存策略仍能确保零售商获得理想的库存绩效,表明文中所建模型在应对供需不确定性方面具有良好的鲁棒性。     

基于农村居民需求演变规律的供给侧创新研究

分析了我国农村居民生产资料和生活资料需求侧的演变特点与规律,认为当农民的收入水平和恩格尔系数达到小康水平时,满足最低农业生产所需的生产资料和基本温饱的生活资料,不会因为农民收入水平的提高而同比率提高;而满足高效率、享受型、健康型的生产资料和生活资料需求却大幅度增长,此时“供给侧”对商品种类和服务种类的供给创新与发展,成为刺激和促进农村居民消费增长的主要因素。今后应在科技、高效、享受、智能、健康等范畴和方面,提升供给侧对农村居民所需商品和服务的创新和发展能力。
