价值共创引导乡村旅游价值链重构

［目的］通过充分发挥移动互联时代消费者对于价值链、创新链、产业链构建的作用，实现价值共创视角下乡村旅游价值链的重构，解决乡村旅游产业中消费者需求和产业供给不平衡不充分之间的矛盾，推动乡村旅游高效、有序、协调、综合发展。［方法］基于价值共创理论，通过文献研究法和系统论方法，探索性重构乡村旅游价值链。［结果］（1）价值共创引导下的乡村旅游价值链是由基本价值活动、辅助价值活动和价值共创活动共同组成，通过虚拟价值链和传统价值链的互动与融合，实现乡村旅游价值链的新价值创造。（2）价值共创活动是以虚拟价值链为基本特征，以“产消者”创新社区为表现形式，依托移动互联网时代的先进技术，创新性赋予旅游者产品生产者和旅游消费者的“产消者”双重属性，通过将消费者从传统价值链的幕后拉向幕前，实现乡村旅游价值链重构和价值增值。［结论］价值共创引导的乡村旅游价值链需要依托平台思维、共享思维和创新思维进行建设，以消费者需求为导向形成的价值链的开放和互动对于实现乡村旅游供给侧结构性改革具有重大意义。     

纳税信用评级结果披露与研发投入

以纳税信用评级披露作为一个天然外生冲击,并基于2013—2016年1214家A股上市公司的微观数据构造准自然实验,使用双重差分法系统评估纳税信用评级结果披露对上市公司研发投入的影响。结果发现:纳税信用评级结果披露显著增加了上市公司的研发投入。基于PSM-DID方法的估计结果与上述结论无明显差异。稳健性检验也表明上述结论的正确性。机制检验表明,纳税信用评级结果披露通过降低企业的融资约束,进而促进企业增加研发投入。此外,分样本回归发现纳税信用评级结果披露只能对中小型企业和民营企业的研发投入产生促进作用。     

Remittances and rural credit markets: Evidence from Senegal

This study investigates the relationship between remittances and credit markets in Senegal, focusing on rural areas where financial constraints are more challenging. Using a household fixed effects model, the findings show that remittances and credit markets are complements; namely, the receipt of remittances is positively associated with the likelihood of having a loan in a household. This means that migrants can increase the reliability of their family members and close relatives back home through their remittances, insuring them vis‐à‐vis lenders for their credit contracts. They are the collateral or the “element of trust” in the credit contract between the borrower and the lender, representing a potential alternative in case of non‐repayment. This result is robust to alternative models and various robustness tests mitigating the potential endogeneity of remittances. A detailed analysis also shows that the relationship between remittances and credit markets is mainly driven by loans taken for consumption and food, in particular, as well as loans provided by informal institutions.     

Tax evasion by tax deferment: Sham litigation with an informal credit market

We show theoretically how tax evasion is facilitated by informal credit market through tax deferment. Our model is empirically based. Using sham litigation, tax evaders earn a higher rate of return than the stipulated penalty rate for tax evasion while the government loses tax revenue. We propose an upfront part–payment of the disputed amount of tax as a solution to the form of tax evasion we describe.     

The effect of consumer food creation on the food consumption experience

Two experiments show that the role the consumer plays in the creation of their food can affect the consumption experience. When guilt is present in the consumption of the food item, namely an unhealthy food item, having someone else create the food item increases taste evaluations, attitudes, and behavioral intentions. However, when guilt is not present, as in the case for healthy foods, there is no difference in food evaluations when the end consumer or another creates the food. These results have important implications for food retailers, food service establishment, and food delivery companies.     

Does Targeted Monetary Policy Matter? A Perspective from China

Several major central banks have experimented with targeted monetary policy to improve credit resource allocation. This policy only applies to ‘eligible’ banks. For example, The People's Bank of China conducted seven targeted reductions of reserve requirements during 2014–15. This article documents the phenomenon of targeted monetary policy and evaluates its effects. The results show that, in the case of China, this policy has generated an extra significant, positive return on the stocks of eligible banks, amounting to 1.2–1.3 per cent in a four‐day treatment period. This substantial return gives commercial banks an extra incentive to align with the policy goals of central banks.     

Assessing the Reliability of Self‐reported Income Information in Informal Small Business Lending through a Bogus Pipeline Experiment

Coping with asymmetric information plays a major role in successful small business lending. Our purpose is to determine if small business applicants report their income information correctly when requesting a loan. We use a randomised controlled trial bogus pipeline experiment, established during a typical cash‐flow analysis of a bank for small businesses in the Philippines. The bogus pipeline approach is commonly applied in social science and aims to increase the rate of truth telling by informing participants that answers will be verified by a lie detector. The experimental data, which include 243 observations of credit clients that are mainly from the agricultural and food value chain, served to identify asymmetric information. Additionally, debtors’ repayment behaviour for approved loans was observed by the bank. Our results indicate that loan applicants of the treatment group report lower incomes, an effect which is most pronounced in lower income quantile. Our analyses also reveal higher loan delinquencies in the control group.     

基于DEA模型的建筑业环境行为效率评价研究

对建筑企业进行环境行为效率评价是促进我国建筑行业健康可持续发展的重要手段。根据建筑行业特点及我国现有的企业环境信用标准,构建了建筑企业环境行为评价的投入产出指标体系,将改进的数据包络分析方法模型运用到企业环境行为效率评价领域,解决了现有企业评价研究主观性突出的问题,得出建筑企业评价分析方法。在此基础上对某代表性建筑企业2010—2017年环境行为数据进行了评价分析。分析结果表明该企业环境行为总体效率良好,但鉴于出现了奇数年和偶数年的效率波动情况,仍需提高环境行为效率。     

What have we learnt about board gender diversity as a business strategy? The appointment of board subcommittees

This paper explores whether a board's gender diversity influences the voluntary formation of its board subcommittees. Female board directorship may become a business strategy for firms if it affects the appointment of board subcommittees. We hypothesize that the voluntary creation of board subcommittees is affected by the presence of female directors on boards; the presence of independent, executive, and institutional female directors; and the proportion of shares held by female directors on boards. Board gender diversity has been measured as a proportion and with Blau's index. The results show that independent female directors are positively associated with the likelihood of voluntarily setting up all or some of the committees and a supervision and control committee. The presence of executive female directors negatively influences the probability of forming all or some of the committees, an executive committee and a supervision and control committee. The percentage of shares held by female directors has a positive effect on the voluntary creation of an executive committee. The findings also report that women directors and institutional female directors do not contribute to the voluntary creation of board subcommittees. Our evidence shows that female board directorship impacts the demand of internal control mechanisms such as board subcommittees, suggesting that firms should take it into account as a business strategy. The main implications derived from this research are relevant for Spanish policymakers and researchers because board gender diversity may play a significant role in the decision‐making processes of firms and may influence firms' outcomes.
