“第一书记”驻村的贫困农户增收效应研究——基于华东某扶贫重点市的实证检验

帮扶单位派驻“第一书记”驻村是我国开展农村扶贫工作的有效方式之一。基于全国扶贫开发信息系统子系统中2016年和2017年华东某扶贫重点市建档立卡贫困农户的数据,采用倾向得分匹配法和双重差分法评估“第一书记”驻村对贫困农户收入的影响,结果表明：派驻“第一书记”确实能有效提高贫困农户收入,市派“第一书记”对贫困农户增收的促进作用显著大于省派和县区派“第一书记”,帮扶主体的层级越高对贫困农户的帮扶越有效的结论不具有普遍性。应推广和完善派驻“第一书记”制度,激励“第一书记”进一步发挥作用,更好地引导、帮助贫困农户脱贫致富,并积极培育乡村可持续发展的内生动力。     

企业精准扶贫行为影响企业风险吗？

精准扶贫是一项国家战略,企业精准扶贫是打赢脱贫攻坚战的重要环节。本文以2016-2018年A股市场参与精准扶贫的非金融类上市公司为样本,研究精准扶贫参与水平对企业风险的影响。研究发现:(1)企业精准扶贫的参与水平越高,其股票市场风险越低;(2)企业信息透明度越低,参与精准扶贫对企业风险的降低作用越强;(3)制度环境越薄弱的地区,参与精准扶贫对企业风险的降低程度越大;(4)进一步分析发现,企业精准扶贫提高了企业声誉、资源获取能力和生产效率,降低了信息不对称,从而有助于降低企业风险。本文研究了企业精准扶贫对企业风险的影响及作用机理,经验证据表明,上市公司积极参与精准扶贫既响应国家号召,为打赢脱贫攻坚战贡献力量,又有利于降低企业风险,能够获得承担社会责任与规避风险的“双赢”结果。     

Real-world dosing and drug costs with everolimus or axitinib as second targeted therapies for advanced renal cell carcinoma: a retrospective chart review in the US

Objective:

To describe dosing patterns and to compare the drug costs per month spent in progression-free survival (PFS) among patients with advanced renal cell carcinoma (aRCC) treated with everolimus or axitinib following a first tyrosine kinase inhibitor (TKI).

Methods:

A medical record retrospective review was conducted among medical oncologists and hematologists/oncologists in the US. Patient eligibility criteria included: (1) age ≥18 years; (2) discontinuation of first TKI (sunitinib, sorafenib, or pazopanib) for medical reasons; (3) initiation of axitinib or everolimus as a second targeted therapy during February 2012–January 2013. Real-world dosing patterns were summarized. Dose-specific drug costs (as of October 2014) were based on wholesale acquisition costs from RED BOOK Online. PFS was compared between everolimus and axitinib using a multivariable Cox proportion hazards model. Everolimus and axitinib drug costs per month of PFS were compared using multivariable gamma regression models.

Results:

A total of 325 patients received everolimus and 127 patients received axitinib as second targeted therapy. Higher proportions of patients treated with axitinib vs everolimus started on a higher than label-recommended starting dose (14% vs 2%) or experienced dose escalation (11% vs 1%) on second targeted therapy. The PFS did not differ significantly between patients receiving everolimus or axitinib (adjusted hazard ratio (HR)?=?1.16; 95% confidence interval [CI]?=?0.73–1.82). After baseline characteristics adjustment, axitinib was associated with 17% ($1830) higher drug costs per month of PFS compared to everolimus ($12,467 vs $10,637; p?<?0.001).

Limitations:

Retrospective observational study design and only drug acquisition costs considered in drug costs estimates.

Conclusions:

Patients with aRCC receiving axitinib as second targeted therapy were more likely to initiate at a higher than label-recommended dose and were more likely to dose escalate than patients receiving everolimus. With similar observed durations of PFS, drug costs were significantly higher—by 17% per month of PFS—with axitinib than with everolimus.     

企业履行社会责任的共赢效应——基于精准扶贫的视角

本文以沪深A股非金融上市公司作为样本,研究实施精准扶贫对扶贫企业以及被扶贫地区的影响。研究发现,对于扶贫企业而言,实施精准扶贫能够显著缓解其融资约束。从扶贫方式来看,产业扶贫和教育扶贫的效果最为明显。从经济后果来看,实施精准扶贫不仅提高了扶贫企业的经营业绩,而且增加了股东的财富水平。对于被扶贫地区而言,精准扶贫显著提高了地区经济发展和居民可支配收入的增长速度,更重要的是,该地区的生态环境并未遭受明显破坏。在企业实施精准扶贫的动机方面,本文发现管理者私利动机并不能解释企业的精准扶贫行为。上述结果表明,与慈善捐赠有所不同,企业实施精准扶贫并不是企业自利的工具,而是利他性动机与战略性动机的结合,能够实现企业、社会与环境三者的共赢。     

Optimal targeted reduction in reserve requirement ratio in China

This study determines the optimal targeted reduction in reserve requirement ratio in China. We find that a targeted reduction in reserve requirement ratio incentivizes commercial banks to reallocate more credit resources to micro and small enterprises, thus eliminating the negative output gap, slightly dampening the rise in unemployment, but also increasing financial instability. Although there is little direct effect on inflation, raising the targeted reduction in reserve requirement ratio can help mitigate the positive effect of output gap on inflation so that an output gap increase is accompanied by a smaller increase in inflation. Optimal rules for targeted reduction in reserve requirement ratio and interest rate policy are derived. Output gap, inflation, and financial instability are three main factors driving the policy dynamics. A targeted reduction in reserve requirement ratio is complementary to interest rate policy, which helps eliminate the negative output gap and allows the interest rate to be less responsive to inflation volatility.     

A consumer segmentation of nutrition information use and its relation to food consumption behaviour

Consumers need information such as nutrition tables to assess the nutritional value of a food product. Although a broad range of studies has examined consumers’ attention, perception and use of nutrition tables, relatively little is known about what types of consumers use what kind of nutrition information. Therefore, using data from the Swiss Food Panel, we conducted a cluster analysis of nutrition information usage and health and nutrition interest to determine whether consumers could be segmented into specific groups. We identified four segments, which we labelled Official Information Users, Internet Users, Moderate Users and Uninterested. We then determined the segments’ demographics, food frequencies and perception of food. Based on our findings, we provide suggestions for targeted interventions that stimulate healthy food choices among these four segments. Our findings imply that nutrition education or the improvement of nutrition labels is unlikely tostimulate nutrition information usage among all consumer types; some consumers may rather benefit more from environmental cues that prime healthy food choices.     

Targeted monetary policy and agriculture business loans

This study examines the effect of a Targeted Easing (TE) policy, an unconventional monetary policy tool initiated by the Chinese central bank to reduce reserve requirement ratios of agricultural financial institutions. Utilizing a longitudinal sample of Chinese agriculture companies and a matching sample of industrial firms between 2012 and 2017, we find that the TE policy successfully achieves its intended policy goal to boost lending to the agriculture sector. Results from our difference-in-differences estimations indicate that loan levels of agriculture firms increases significantly more than that of matching nonagricultural firms under TE relative to the non-TE period. We also document heterogeneous TE effects and find that agricultural firms with smaller agency costs, larger financing constraints, and larger loan intensity levels benefit significantly more from a TE policy than their counterparts. In addition, the TE policy effect is more salient during a contractionary period than in an expansionary period.     

Forecasting national activity using lots of international predictors: An application to New Zealand

We assess the marginal predictive content of a large international dataset for forecasting GDP in New Zealand, an archetypal small open economy. We apply “data-rich” factor and shrinkage methods to efficiently handle hundreds of predictor series from many countries. The methods covered are principal components, targeted predictors, weighted principal components, partial least squares, elastic net and ridge regression. We find that exploiting a large international dataset can improve forecasts relative to data-rich approaches based on a large national dataset only, and also relative to more traditional approaches based on small datasets. This is in spite of New Zealand’s business and consumer confidence and expectations data capturing a substantial proportion of the predictive information in the international data. The largest forecasting accuracy gains from including international predictors are at longer forecast horizons. The forecasting performance achievable with the data-rich methods differs widely, with shrinkage methods and partial least squares performing best in handling the international data.
