ABSTRACT Policymakers have little experience regarding designing the right levels of pricing for plastic bags. The ineffectiveness of charging for bags, in countries such as South Africa, makes it imperative that we map the demand curve. Getting the charge “right” depends on the size of the externality. Charging for bags is therefore an effective intervention to encourage consumers to carry their own bags to the stores. We employ a contingent behaviour (CB) dataset necessary to estimate the charge level that is likely to lead to a reduction in bag use over time. The results of the random effects Tobit model suggest that the current charge of US$0.03 was found to be too low, and highly inelastic. A charge of US$0.50 has potential to reduce unnecessary plastic use and is still lower than the price of alternatives; therefore, there is no danger of consumers shifting to alternatives that may cause more harm.
决策者在为塑料袋设计合适的定价水平方面缺乏经验。在南非等国家,塑料袋收费的无效使得我们有必要绘制需求曲线。收费“正确”与否取决于外部性的大小。因此,对塑料袋收费是一种有效的干预措施,鼓励消费者自己携带塑料袋去商店。我们采用了一个偶然行为(CB)数据集来估计随着时间的推移可能导致塑料袋使用减少的收费水平。随机效应Tobit模型的结果表明,目前0.03美元的收费太低,而且高度缺乏弹性。0.5美元的收费有可能减少不必要的塑料使用,而且仍然低于替代品的价格;因此,不存在消费者转向可能造成更大伤害的替代品的危险。

ABSTRACT This paper applies a Qual VAR approach to generate a continuous banking crisis indicator from an underlying latent variable using a Markov Chain Monte Carlo algorithm. Four decades of banking crises are assessed by accounting for the evolutionary nature of precursors, as measured through periodic, regional, and developmental effects using a representative sample of countries. Aggregate results from forecast error variance decomposition show that banking sector variables explain nearly half of total variation, external sector a third and real sector a fifth. Findings suggest that recursive out-of-sample forecasts up to 12-months preceding a banking crisis render vital early warning signals, and as based on quarterly data, support expeditious response times. In out-of-sample forecasting, the Qual VAR outperforms a probit model. Improved forecasting performance may assist banking oversight departments and support remediation efforts of policymakers to adequately and timeously respond to banking crises.
摘要本文应用一种Qual-VAR方法,使用马尔可夫链蒙特卡罗算法从潜在变量中生成连续的银行危机指标。四十年来的银行危机是通过考虑前体的演变性质来评估的,这是通过使用具有代表性的国家样本通过周期性、区域性和发展性影响来衡量的。预测误差方差分解的总体结果表明,银行部门变量解释了近一半的总方差,外部部门解释了三分之一,实体部门解释了五分之一。调查结果表明,在银行危机发生前12个月内,递归的样本外预测提供了重要的预警信号,并根据季度数据支持快速响应。在样本外预测中,Qual-VAR的性能优于probit模型。预测绩效的提高可能有助于银行监管部门,并支持决策者的补救工作,以充分及时地应对银行危机。

The interrelationships between bank risk and charter value in ASIAN-5 亚洲银行风险与特许经营价值的相互关系
IF 1.8 4区 经济学 Q3 ECONOMICS Pub Date : 2022-09-13 DOI: 10.1080/15140326.2022.2118514

ABSTRACT This study examines the interrelationships between bank risk and charter value in five countries in Southeast Asia (ASEAN-5) from 2006 to 2019 using a simultaneous equations model. The findings show a two-way relationship between bank risk and charter value. More specifically, the positive relationship between charter value and bank risk implies that banks with a more excellent charter value tend to pursue fast growth strategies and thus may face a higher risk. This positive link, however, only holds up to a certain level of charter value. On the other hand, the negative impact of bank risk on charter value argues that more risky banks tend to generate lower returns, thus reducing charter value. Additionally, a bidirectional relationship between them still holds when using an alternative measure of bank risk and controlling for the global financial crisis and governance indicators. Therefore, our findings provide critical implications for policymakers, managers, and academics.
摘要本研究采用联立方程模型考察了2006年至2019年东南亚五国(东盟五国)银行风险与特许经营价值之间的相互关系。研究结果表明,银行风险与特许经营价值之间存在双向关系。更具体地说,特许经营价值与银行风险之间的正相关关系意味着,特许经营价值越优秀的银行往往追求快速增长战略,因此可能面临更高的风险。然而,这种积极的联系只适用于一定程度的包租价值。另一方面,银行风险对租船价值的负面影响认为,风险越大的银行往往产生较低的回报,从而降低租船价值。此外,当使用另一种银行风险衡量标准并控制全球金融危机和治理指标时,它们之间的双向关系仍然成立。因此,我们的研究结果为政策制定者、管理者和学者提供了重要的启示。

ABSTRACT This paper studies whether firms’ corporate social responsibility (CSR) affects their access to trade credit in response to monetary contraction shocks. Based on US firm-level data from 1995Q1 to 2014Q1, we find that after monetary contraction shocks, firms with higher levels of CSR receive more trade credit than firms with lower levels of CSR. Moreover, the beneficial impact of CSR is stronger for firms in regions with higher social trust and in more competitive industries. The interpretation of the observed phenomena is that the high-CSR firms are regarded as more trustworthy.
摘要本文研究了在货币紧缩冲击下,企业的企业社会责任(CSR)是否会影响其获得贸易信贷的机会。基于1995年第一季度至2014年第一季度的美国企业层面数据,我们发现在货币紧缩冲击后,企业社会责任水平较高的企业比企业社会责任程度较低的企业获得更多的贸易信贷。此外,企业社会责任对社会信任度较高地区和竞争更激烈行业的企业的有益影响更大。对观察到的现象的解释是,高企业社会责任企业被认为更值得信赖。

ABSTRACT This paper explores how the anticipated expenditure on children’s college education affects household asset allocation, applying a two-stage budgeting model of asset demand by using the 2016 China Family Panel Studies Data (CFPS). The empirical results show that if a household plans to send a child to college, the probability of holding risky assets increases by 1.7 percentage points, and the probability of holding investable housing assets increases by 3.8 percentage points. Furthermore, we also find that as the expected year of college entry approaches, households prefer less liquid assets. When the expected year is still far in the future, they prefer liquid assets with high-risk and illiquid assets with high-return. These findings imply that policymakers should make reforms in the financial market and real estate market, as well as provide more kinds of investment products, thereby promoting household investment diversification.
摘要本文利用2016年中国家庭面板研究数据,应用资产需求的两阶段预算模型,探讨了儿童大学教育的预期支出如何影响家庭资产配置。实证结果显示,如果一个家庭计划送孩子上大学,持有风险资产的概率会增加1.7个百分点,持有可投资住房资产的概率则会增加3.8个百分点。此外,我们还发现,随着预期的大学入学年份的临近,家庭更喜欢流动性较差的资产。当预期的一年还在遥远的未来时,他们更喜欢高风险和非流动性高回报的流动资产。这些发现意味着政策制定者应该在金融市场和房地产市场进行改革,并提供更多种类的投资产品,从而促进家庭投资多元化。

ABSTRACT An increase in trade policy uncertainty raises policymakers’ concerns, as it can be harmful to investments and growth globally. This study examines the impact of reducing trade policy uncertainty on export product quality. Based on the ASEAN–China Free Trade Area (ACFTA), the difference-in-difference, two-way fixed, and triple difference methods were used to conduct benchmark tests. The results show that reducing trade policy uncertainty improves export product quality. Social capital has strengthened the role of the changing trade environments. The results were robust after the PSM-DID, placebo test, and deletion of outliers. Furthermore, the role of social capital is incorporated into the regression model. From the perspective of informal internal systems, this study expands the theoretical view of regional trade integration research and answers the current trade strategy adjustment and export transformation policy concerns.
摘要贸易政策不确定性的增加引起了决策者的担忧,因为这可能对全球投资和增长有害。本研究考察了减少贸易政策不确定性对出口产品质量的影响。以中国—东盟自由贸易区为例,采用差分法、双向固定法和三重差分法进行基准测试。结果表明,减少贸易政策的不确定性可以提高出口产品的质量。社会资本加强了不断变化的贸易环境的作用。PSM-DID、安慰剂试验和删除异常值后,结果是稳健的。此外,社会资本的作用被纳入回归模型。本研究从非正式内部系统的角度,拓展了区域贸易一体化研究的理论视野,回答了当前贸易战略调整和出口转型政策关注的问题。

ABSTRACT We investigate the impact of European Union (EU) integration on capital flows to prospective new EU member states. Using annual data between 1992 and 2020, our results suggest that although EU integration increased net capital flows before the Global Financial Crisis (GFC), it was not able to shield countries from the general decline in capital flows that occurred after the GFC. Furthermore, the results show that the impact of EU integration mainly runs through improved institutional quality. We also find considerable heterogeneity in the drivers of different types of capital flows (FDI, portfolio investments, and other capital flows) that we consider.
摘要本文研究了欧盟一体化对欧盟新成员国资本流动的影响。使用1992年至2020年的年度数据,我们的结果表明,尽管欧盟一体化在全球金融危机(GFC)之前增加了净资本流动,但它并不能保护各国免受全球金融危机后资本流动普遍下降的影响。此外,研究结果表明,欧盟一体化的影响主要体现在制度质量的提高上。我们还发现,我们所考虑的不同类型资本流动(FDI、证券投资和其他资本流动)的驱动因素存在相当大的异质性。

ABSTRACT This paper analyses the impact of matching frictions in the Portuguese labour market on individual unemployment hazard rates and unemployment durations. The coexistence of permanent contracts and temporary contracts in the Portuguese (dual) labour-market is akin to a matching friction, with a contract-type mismatch between jobseekers who prefer permanent contracts, whereas firms, in turn, prefer to offer temporary contracts. The paper uses a rich micro dataset which allows to compute a time and space varying contract-type mismatch index, over 86 local labour markets (job-centers of the Portuguese Public Employment System) and five years. Employing discrete time hazard models and a stock-flow matching mechanism, we find that local labour markets with higher contract-type mismatch rates are characterized by lower hazard rates and longer unemployment duration. Improving the desirability of temporary contracts and information about local contract-type mismatch rates may reduce matching frictions and average unemployment duration.
摘要本文分析了葡萄牙劳动力市场中匹配摩擦对个人失业危险率和失业持续时间的影响。在葡萄牙(双重)劳动力市场中,长期合同和临时合同的共存类似于匹配摩擦,求职者喜欢长期合同,而公司则倾向于提供临时合同,两者之间的合同类型不匹配。本文使用了一个丰富的微观数据集,该数据集允许计算时间和空间变化的合同类型不匹配指数,超过86个当地劳动力市场(葡萄牙公共就业系统的就业中心)和五年。利用离散时间风险模型和存量流量匹配机制,我们发现契约型错配率较高的地方劳动力市场具有风险率较低、失业持续时间较长的特征。提高临时合同的可取性和关于当地合同类型不匹配率的信息可以减少匹配摩擦和平均失业持续时间。

ABSTRACT Innovation capability of manufacturing industry is one of the most important factors that determine a country’s competitiveness. This paper expounds the theoretical and empirical relationship among innovation capability (IC), capital enrichment (CE) and total factor productivity (TFP) by using the yearly panel data of 28 Chinese manufacturing segments from 2011 to 2018. The intermediary effect model and threshold model are used for empirical analysis, findings suggest that 1) IC not only directly promotes TFP but also indirectly through CE, indicating that CE has an intermediary effect on the relationship between IC and TFP. 2) The positive effect of CE on TFP is influenced by the “double threshold effect” of IC. Compared with industries having low IC, this positive effect in high IC industries is first enhanced then weakened and later re-enhanced. 3) There is a significant difference in IC and CE among different manufacturing segments.
制造业的创新能力是决定一个国家竞争力的重要因素之一。本文利用2011-2018年中国28个制造业部门的年度面板数据,阐述了创新能力(IC)、资本富集度(CE)和全要素生产率(TFP)之间的理论和实证关系。采用中介效应模型和阈值模型进行实证分析,结果表明:1)IC不仅直接促进TFP,而且通过CE间接促进TFP的产生,表明CE对IC与TFP的关系具有中介效应。2) CE对TFP的正向作用受到IC“双阈值效应”的影响。与低集成度行业相比,高集成度行业的这种积极作用先增强后减弱,然后再增强。3) 不同制造部门在IC和CE方面存在显著差异。

Compared with industries having low IC, this positive effect in high IC industries is first enhanced then weakened and later re-enhanced. 3) There is a significant difference in IC and CE among different manufacturing segments.","PeriodicalId":51747,"journal":{"name":"Journal of Applied Economics","volume":"25 1","pages":"644 - 667"},"PeriodicalIF":1.8,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46355589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT This paper analyzes the impact of high-speed train construction on enterprise innovation and its specific mechanisms by establishing high-speed train-city-firm level panel data and constructing a multi-period DID model in China. The results show that, firstly, the construction of a high-speed train significantly improves the innovation level of enterprises, and the construction of the first high-speed train can increase the number of patents of local listed enterprises by about 11.5%. Second, the impact of high-speed train construction on the innovation level of listed enterprises is mainly through the internal human capital and external marketization of enterprises. Specifically, the high-speed train construction affects innovation by weakening the transportation distance; on the other hand, it improves the external market environment and enhances the market competition, making firms seek innovation actively.
本文通过建立中国高铁-城市-企业水平面板数据,构建多时期DID模型,分析了高铁建设对企业创新的影响及其具体机制。结果表明:第一,高铁的建设显著提高了企业的创新水平,首列高铁的建设可使当地上市企业的专利数量增加约11.5%;第二,高铁建设对上市企业创新水平的影响主要是通过企业内部的人力资本和外部的市场化。具体而言,高铁建设通过削弱运输距离影响创新;另一方面,它改善了外部市场环境,增强了市场竞争,使企业积极寻求创新。
