ENDOGENOUS TIMING IN QUALITY CHOICES AND PRICE COMPETITION

We modify the price‐setting version of the vertically differentiated duopoly model by Aoki (2003) by introducing an extended game in which firms noncooperatively choose the timing of moves at the quality stage. Our results show that there are multiple equilibria in pure strategies, whereby firms always select sequential play at the quality stage. We also investigate the mixed‐strategy equilibrium, revealing that the probability of generating outcomes out of equilibrium is higher than the probability of playing one Nash equilibria in pure strategies. In the alternative case with full market coverage, we show that the quality stage is solved in dominant strategies and therefore the choice of roles becomes irrelevant as the Nash and Stackelberg solutions coincide. With full market coverage and corner solution, the results show that the game has a unique subgame perfect equilibrium in pure strategies, where the high‐quality firm takes the lead in the quality stage.     

The Challenge of Humanistic Economics

The Center for Medicare and Medicaid Services (CMS) created the Hospital Compare Program in 2003 to increase transparency between healthcare providers and consumers. Implemented in 2005, this transparency consists of hospitals' collecting and making publicly available a set of hospital quality score measures. The CMS induced participation by financially penalizing hospitals that did not publicly report a specific subset of these measures (called “starter” measures). Three years into the program, the penalty for non-reporting both the starter measures and other (“non-starter”) measures was increased. I use a difference-in-differences methodology to analyze the effect of the increased CMS penalty on the likelihood that a hospital publicly reported its starter and non-starter measure scores. I find that the penalty had an economically and statistically insignificant effect on the probability that a hospital publicly reported its starter scores, but a statistically significant 8.0 percent effect (p-value<0.01) on whether it reported its non-starter scores. These findings are robust to a series of alternative empirical specifications.     

Mixed Market Competition in a Quality Differentiated Duopoly Model An Approach to Banking Sector

This paper attempts to develop a theoretical framework to investigate the competitive implications of quality choices of financial institutions whereby they charge prices to consumers based on their willingness to pay for the service qualities in the mixed market scenario under vertical product differentiation model. Initially, it analyzes benchmark equilibrium solutions of monopoly and duopoly to establish the degree of quality differentiation between two private banks in an uncover market configuration. Further, it estimates the quality differentiation between private and public banks, and examines the interaction between two market structures keeping public bank as both leader and follower, and then measures the social welfare from different prospectives. The explicit operation of two stages Nash equilibrium game forecasted that public banks＇ monopoly seems to be still better than a private banking, and it is socially optimal. The outcome demonstrates a significant importance of vertical quality differentiation for policy implication in banking industry and provides an insight on the reasons of particular co-existence of public and private banking services in the specified location. In this context, it is concluded that the presence of public banks in banking industries is a crucial condition for obtaining the higher range of social welfare.     

资本市场发展影响货币需求的实证研究

从理论上分析,资本市场发展对货币需求存在正向影响的财富效应和负向影响的替代效应,但对中国的资本市场发展及货币需求数据进行实证分析发现,资本市场发展提高了经济体的货币需求;股票成交金额的变动有助于我们对于狭义货币供应量的预测,不过在统计上无助于我们对于广义货币供应量的预测。考虑到资本市场发展因素,货币政策从紧的力度应该比单纯考虑实体经济货币需求的从紧力度略松。     

Using paradata to collect better survey data: Evidence from a household survey in Tanzania

Data are a key component in the design, implementation, and evaluation of economic and social policies. Monitoring data quality is an essential part of any serious, large‐scale data collection process. The purpose of this article is to show how paradata should be used before, during, and after data collection to monitor and improve data quality. To do this we use timestamps, global positioning system (GPS) coordinates, and other paradata collected from an 800‐household survey conducted in Tanzania in 2016. We demonstrate how key paradata can be used during each phase of a research project to identify and prevent issues in the data and the methods used to collect it. Our results corroborate the importance of collecting and analyzing paradata to monitor fieldwork and ensuring data quality for micro data collection in developing countries. Based on these findings we also make recommendations as to how researchers can make better use of paradata in the future to manage and improve data quality. We argue for an expansion in the understanding and use of varied paradata among researchers, and a greater focus on its use for improving data quality.     

Can innovation shocks determine CO2 emissions (CO2e) in the OECD economies? A new perspective

ABSTRACT

This study has attempted to address prior knowledge gaps in the environmental economics literature by integrating the innovation shocks into the Environment Kuznets Curve (EKC) equation for twenty-six OECD economies using data from 1990 to 2014. Foreign direct investment (FDI), exports (EXP), renewable energy consumption (REC), and GDP per capita were included as control variables. The results from multiple empirical analyses indicated that positive shocks to innovation improve, but the negative shocks disrupt environmental quality. Data analyses also showed that a positive correlation exists between income per capita of OECD economies. From the negative coefficient of income per capita (squared) and the existence of a negative nexus between FDI and CO2e, both the EKC and the Pollution Halo Hypothesis (PHH) were confirmed in sampled economies, respectively. The paper offers empirical support for the favourable impacts of REC on the quality of the environment and calls for the adoption of innovation shocks as a policy instrument to formulate better environmental policies for a sustainable future.     

基于QFD方法的服务型制造企业服务质量改进研究

构建基于QFD方法的服务型制造企业服务质量改进研究模型,通过SPSS软件,对实例Y公司顾客需求的权重进行主成分分析,在此基础上运用灰色理论和模糊数学相结合的灰色模糊方法对Y公司服务质量进行评价,然后结合测评结果运用QFD方法,找到Y公司应该着力加强的服务措施。研究结果表明,权重分数较高的服务措施要素是进行服务补救、信息系统、员工素质、办事效率和培训,即要Y公司满足客户质量需求必须关注的要素,这些要素的好坏,直接决定了企业客户需求是否得到了满足。这类研究方法,对类似的服务型制造企业服务质量改进的研究,同样有很大的借鉴意义。
