New development: China renews reform of central–local fiscal relations and provides for basic national public services

China’s reform on central–local fiscal reform has slowed down in recent years. The appointment of a new finance minister experienced in local government affairs is expected to renew the reform affirmed by the Chinese Communist Party (CCP) congress in late 2017. China has unprecedentedly identified a comprehensive list of 81 national basic public services as entitlements. Eighteen of them are subject to national and local standards, and co-financed by central and local governments. A new cost-sharing method for 10 of these services classifies sub-national jurisdictions into five tiers, in which the central government’s share declines from 80% to 10%. These measures, effective in 2019, aim at creating a ‘harmonious and moderately prosperous society’.     

企业基础研究行为驱动模型构建

预期寿命、生育率变动与基本养老保险统筹账户调整

在构建三期世代交叠模型的基础上，通过选取相关制度指标来模拟分析在未来预期寿命和生育率变动下，基本养老保险统筹账户如何基于参数调整来维持收支平衡。研究结果表明：（1）我国居民预期寿命增长过快，统筹账户收支平衡受预期寿命变化影响较大；（2）在现阶段的预期寿命和生育率条件下，统筹账户能实现自身收支平衡，而且可在短期内通过阶段性降低缴费率来促进制度长远发展；（3）在长期内需通过提高缴费率或降低养老金替代率来保证统筹账户收支平衡，预期寿命为87.828岁且总和生育率为1.79作为参数调整临界点；（4）以现有制度设计为基准，参数调整临界点之前保证35%的基础养老金平均替代率不降，临界点之后保证20%的缴费率不升可以最大程度促进经济和社会发展。     

How to optimize the allocation of research resources? An empirical study based on output and substitution elasticities of universities in Chinese provincial level

Although significant progress has been made in China's basic research in recent years, there remains a wide gap between research in China and that from developed countries. How to optimize the allocative efficiency of research resources is of great importance for increasing research output. In this paper, using the fixed effect stochastic frontier model based on the translog production function, we estimate output and substitution elasticities of research and development (R&D) inputs at universities in China's provincial level during 2009–2016. We find that the R&D technical efficiency of China's universities, after a rapid growth, has tended to become relatively stable. Improvements of internationalization degree and exogenous R&D capabilities are conducive to promoting R&D technical efficiency, whereas expenditures from government grants inhibit the promotion of R&D technical efficiency; the effects of R&D capital deepening and internet penetration are not evident. The output elasticity of R&D capital is much higher than that of R&D personnel, suggesting that R&D capital is the main driving force of research output. The substitution elasticity between R&D capital and personnel has experienced a change from substitution to complementary since 2014. To realize sustained growth of research output, we should increase R&D input with positive output elasticity or reduce R&D input with negative output elasticity, making the necessary trade-offs according to the substitution relationship between the two R&D inputs.     

Time-varying beta in functional factor models: Evidence from China

In this paper, we introduce a functional method to investigate how betas change over time in factor models. Based on the China A-share data, we drop the constant beta assumption in the CAPM and multi-factor models to estimate the time-varying betas directly from the functional data regression. The empirical results show that exposures to all risk factors have certain time-varying patterns in the Chinese A-share stock market.     

On the global supply of basic research

In a two-country Schumpeterian growth model, we study the incentives for basic research investments by governments in a globalized world. A country׳s basic research investments increase with the country׳s level of human capital and decline with its own market size. This may explain why some smaller countries invest so much in basic research. Compared with the optimal investments achievable when countries coordinate their basic research policies, a single country may over-invest in basic research. However, the total amount of decentralized basic research investments is always below the socially optimal investment level, which justifies policy coordination in this area.

When nature calls: The role of customer toilets in retail stores

The scarce previous literature indicates that the customer toilet facilities influence shopping value and should be a concern for retailers. However, customer toilets are often inadequately capitalised in retail stores. This study aims to provide a scientifically robust argument about the critical role of customer toilets in retail stores. The explanatory survey data (n=655) from a Finnish out-of-town department store is examined to explore (1) the importance that consumers place on the customer toilets and (2) the effect of toilet usage on actual shopping behaviour. The results support the assumptions of previous literature by suggesting that customer toilets are considered as an important store attribute and, more importantly, the use of toilets is associated with prolonged in-store time which, in turn, increases spending. The findings offer both academic and managerial contribution and encourage academics and practitioners to regard customer toilets as more than mere an unwanted property expense and discover their full marketing potential.     

Impact of MGNREGA on the livelihood security of rural poor in India: a study using national sample survey data

This paper studies the impact of the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGA) at the all-India level utilizing nationally representative data from the national sample survey (NSS). We propose an alternative methodology for the proper identification of target households in the baseline period using a secondary data source such as the NSS. The programme is assessed in terms of whether it has been successful in ensuring livelihood security for beneficiary households. The study found that the increase in spending capacity of non-beneficiary households was greater than MGNREGA beneficiary households. Moreover, the overall growth trend in spending capacity over time had a greater effect in improving the livelihood security of the target households than the estimated effect of the programme.
