VIX futures term structure and the expectations hypothesis

Tests of the expectations hypothesis reveal that the slope of the VIX futures term structure predicts the direction but not the magnitude of the evolution of the short-end of the curve, but predicts neither the direction nor the magnitude of short-term changes in the long-end of the curve. Relative value seeking spread trades, constructed to exploit such violations, deliver excess returns with annualized Sharpe ratios equal or greater than those of volatility-writing strategies deployed by VIX ETN's for a majority of the 32 spread trade combinations tested. I demonstrate that profits from beta-neutral variations of the spread trades, which are not compensation for taking on equity downside risk by design, are propagated by inflows of capital into VIX futures markets, after controlling for factors that measure changes in the availability of hedge fund capital, risk appetite, and momentum. At the heart of profits, and by extension the term structure anomalies, is a disproportionally elevated basis propagated by long VIX demand that enters the futures market through ETN channels.     

Monetary Policy Uncertainty and the Response of the Yield Curve to Policy Shocks

This paper studies the nonlinear response of the term structure of interest rates to monetary policy shocks and presents a new stylized fact. We show that uncertainty about monetary policy changes the way the term structure responds to monetary policy. A policy tightening leads to a significantly smaller increase in long-term bond yields if policy uncertainty is high at the time of the shock. We also look at the decomposition of bond yields into expectations about future policy and the term premium. The weaker response of yields is driven by the fall in term premia, which fall more strongly if uncertainty about policy is high. Conditional on a monetary policy shock, higher uncertainty about monetary policy tends to make securities with longer maturities relatively more attractive to investors. As a consequence, investors demand even lower term premia. These findings are robust to the measurement of monetary policy uncertainty, the definition of the monetary policy shock, and to changing the model specification.     

Official Demand for U.S. Debt: Implications for U.S. Real Rates

We estimate a structural term-structure model of U.S. real rates, where arbitrageurs accommodate demand pressures exerted by domestic and foreign official investors. Official demand affects rates by altering the aggregate price of duration risk, and thereby bond risk premiums. Although foreign central banks' demand contributed to reduce long-term real rates mainly in the years prior to the global-financial crisis, the Federal Reserve's demand lowered rates during the quantitative easing period. Overall, the two-factor model, augmented to account for changing liquidity conditions, offers a good representation of real rates during the 2001–16 period; however, we flag some caveats and possible extensions.     

Cognitive foundations of firm internationalization: A systematic review and agenda for future research

Managerial cognition has a fundamental role in the internationalization of firms. However, there exists no coherent understanding of how prior research has examined and captured the cognitive foundations of internationalization. This paper provides a systematic review of this body of literature. The review identifies three main streams of research that, overall, consists of nine more specific research areas. We show that especially the areas addressing (1) managerial learning, (2) characteristics of upper echelons, (3) intra-organizational perceptions, and (4) external actors’ perceptions provide opportunities for the further advancement of internationalization literature. For harnessing these opportunities, we find that the microfoundational approach could support the empirical examination of the cognitive foundations and would notably contribute to the Uppsala model-based theorization of the firm internationalization process.     

将“合伙人制”融入“合作制”的一项尝试——基于MGL合作社的案例解读与探讨

当前,合作社异化已成为阻碍合作社进一步发展的痛点,其中"合作制"下社员剩余索取权和控制权的丧失是矛盾核心,因而探求其改进方式对合作社长远发展、实现乡村振兴有重要意义。本文基于效率与公平衡量维度,通过对MGL合作社这一典型案例进行剖析发现,有效的合作社在治理结构和利益分配上具备"合伙人制"特征,并且基本契合不完全契约理论有关能够有效解决契约双方信息不对称以及剩余索取权、控制权被少数社员占有的论述。对此,应充分重视合伙人制在合作社发展中的内在有效性,弱化其是否具有规范的外在形式。     

Agricultural holdings with undefined boundaries,communal systems and counter‐hegemonies: The persistence of the peasantry in Argentina

The presence of agricultural holdings with undefined boundaries (AHUBs) and their heterogeneous geographical distribution questions the supposed hegemony of agribusiness in Argentina. Given the lack of defined boundaries, these holdings generate a communal culture among dwellers, which is reflected in both the strategies of the use of commons and the initiatives for the defence of land in the conflicts between peasants and entrepreneurs. This article describes two counter‐enclosure experiences that were generated and have developed on the bedrock of AHUBs and a communal matrix. Those defence strategies are employed by families that possess the land but have not title to it, being a defence tactic against attempts of eviction. AHUB not only is a new census category that allows us to enhance our knowledge of the rural world but also proposes modes of production that differ from those of the capitalist model, showing possible counter‐hegemonic development alternatives that arise from the practices used in these holdings.

畜牧产业结构变动对我国粮食安全的影响分析

［目的］改革开放40多年来，我国畜牧产业结构不断调整和优化，其生产供给结构与消费需求结构的变动与我国粮食安全问题息息相关。［方法］文章基于改革开放40多年来畜牧产业发展历程，从供给与需求两个维度分析我国畜牧产业结构变动的特征，并进一步探究畜牧产业结构变动与我国粮食安全间的作用机理，最后运用灰色关联度分析法实证其关联影响度。［结果］我国畜牧产业结构由耗粮型为主向节粮型转变，畜产品供给结构趋于合理，但不同区域间存在较大差异； 我国居民对畜产品消费需求量增加，但城乡居民畜产品消费结构及变动存在一定差异性； 畜牧产业结构变动与粮食安全有重要联系，畜牧业发展同保障国家粮食安全并不矛盾，畜牧产业结构变动主要通过耕地、基于口粮替代的食物需求结构变化及饲料粮需求3个方面作用于粮食安全； 具体来看，粮食播种面积、耗粮型畜产品比重和耗粮型畜产品饲料转化率对粮食安全水平的关联影响较大，节粮型畜产品比重与节粮型畜产品饲料转化率对粮食安全水平的关联影响小于耗粮型畜产品的影响。［结论］不断提高不同畜产品的饲料转化率，加大非粮型饲料资源开发利用度，推广非粮饲料应用技术，加快畜牧产业转型升级，满足消费者需求和保障国家粮食安全。     

中国农村减贫成效测度、分解及影响因素研究——基于分布动态学框架的CFPS数据分析

测算农村减贫成效并考察减贫成效的影响因素对我国打赢"脱贫攻坚战"具有重要的现实意义。本文基于覆盖我国东、中、西和东北四大地区的CFPS调查数据,在Quah(1997)的分布动态学(Distribution dynamics)基础上构建了完整的减贫成效分析框架。首先测算出各地区农村家庭贫困内部状态的Markov转移概率矩阵,并在此基础上构建了可分解的绝对、相对减贫指数,以综合考察各地区的农村减贫成效,随后本文通过首次构造的"条件Markov模型"进一步考察了减贫成效的影响因素。研究结果发现:(1)样本考察期内,我国各地区的农村贫困状况随着时间的积累逐渐变好,贫困发生率均有所下降;(2)减贫过程中仍存在着脱贫又返贫的现象,农村家庭的深度贫困固化问题比轻度贫困问题更加严重,意味着扶贫开发工作正式进入攻坚时期,扶贫难度加大;(3)家庭成年成员特征、家庭特征以及收入类型对农村减贫成效的影响显著性情况存在着时段和区域的异质性。其中,家庭成年成员受教育水平、家庭中是否有成员从事有薪酬的农业劳动、工资性和营业性收入对家庭的贫困状态变动具有更显著的影响。基于此,政府应贯彻落实精准扶贫,将扶贫重点放在中西部地区和处于深度贫困的家庭,另外应再调整和倾斜扶贫资源与扶贫政策,将提高农民受教育水平、增加非农业就业机会作为主要减贫途径,将促进农村工资性和营业性收入增长作为主要的政策倾斜方向。
