Relying on the adaptive expectations Augmented Phillips Curve approach, the study estimated the sacrifice ratio for inflation that is conducive for growth in Nigeria and found the ratios for the constructed models I and II to be positive. The sacrifice ratio measures how much output is lost in the country when inflation is reduced by 1 percentage point through monetary policy action. The outcome of our study suggests that a 1 percent disinflation accomplishment leads to an output loss of 0.07%. Also, for a given period, power of persistence effect coefficient is 0.71 on the average, suggesting that, disinflation policy has a more robust and long-lasting impact on the country’s real GDP.

Economic development is thus a multivariate concept; hence there is no single satisfactory definition of it. Development is conventionally measured as economic growth with level of development in the process of size of economy. A country’s economic health can usually be measured by looking at that country’s economic growth and development. Most of the economists clamored for dethronement of GNP and define development in terms of removal of poverty, illiteracy, disease and changes in the composition of input and output, increase in per capita output of material goods.
Analysis of commercial automobile insurance operating efficiency and Its influence factors of Chinese property insurance companies -An empirical analysis based on SBM-DEA method and Tobit model
This paper selects the operation data of commercial car insurance of 25 companies in 2012-2016, and calculates the efficiency of commercial car insurance by using SBM-DEA model, also analyzes the main factors affecting the efficiency of commercial car insurance operation by using the Tobit panel data estimation model. The main conclusions are as follows: 1. The overall efficiency value of the commercial insurance company is low, and only 2 of the 25 property insurance companies tested reached the effective frontier, there is still a large space for improvement, the redundancy of low efficiency companies is more serious; In the past three years, the technical efficiency value has remained stable and the upward trend is not obvious. 2. Commercial car insurance premium income share, market share, cost rate, company asset size, all have different degrees of impact on the efficiency value of commercial car insurance.
The chapter I of this article elaborates the background and significance of the topic research, sorts out the domestic and foreign scholars’ research on consumer finance companies. Chapter 2 first introduced the concept, characteristics, supply and demand of consumer finance. The third chapter analyzes the development status of China’s consumer finance companies, and finds that the number of consumer finance companies has developed rapidly, and the profitability level is high; the products have been continuously upgraded and marketing channels are abundant; the business-driven model has been driven from the fund to the scene-driven and technology-driven. Afterwards, the BOC Consumer Finance Corporation was used as a typical domestic case for in-depth analysis. Chapter 4 concludes the problems encountered by China’s consumer finance companies in the development process. The fifth chapter proposes the following countermeasures based on the development of China’s consumer finance companies: changing consumer attitudes; broadening financing channels, increasing tax incentives, training financial and scientific talents, and improving the social credit system.

With changing conditions of the financial environment, relative issues of non-audit services still require further developments and researches, concerning their rationale and risks that can be admitted so far, and influences of latest regulations. Here the rationale and risks of NAS were investigated through summarizing prior studies. Some researchers believe that there is a trade-off effect between advantages and disadvantages of NAS, therefore, it can be accordingly concluded that there is at least net effect in NAS’s downsides and upsides, the rationality of NAS can be prove based on this sight. However, many latest researches tend to believe NAS has adverse impacts.
Purpose of this paper – This study aims to contribute to the debate in service marketing literature concerning the operationalisation of service quality measurement. To this effect, we tested two service quality measurement models by adapting them to the audit service context. These models are the gap model (SERVQUAL) developed by Parasuraman, Berry, and Zeithaml (1985) and the performance-only (SERVPERF) model developed by Cronin and Taylor (1992). Design/methodology/approach – The models are quantitatively analysed and evaluated for construct validity and predictive power using OLS models. In line with marketing literature (Gronroos 1984), service quality dimensions are classified into technical and functional dimensions. Construct validity is measured in terms of whether the technical and functional dimensions of audit service quality are significantly positively correlated with an overall measure of service quality in the audit service market. Predictive power is measured in terms of the strength of adjusted R2. Findings – The results indicate that both the performance-only model and the gap model have done quite well in predicting determinants of overall audit quality. The argument by Cronin and Taylor (1992) that the gap model has low explanatory power compared to the performance-only model did not materialise in our study. Research limitations/implications – Our results are limited by the low response rate that did not allow us to conduct factor analysis on all the functional and technical variables at the same time. What is original/value of paper – The paper shows that the service marketing models for the measurement of quality would be improved when core outcome (technical) variables are incorporated.
The study endeavors to investigate the determinants of mobile phone usage (adoption) using data from Central Region in Eritrea. Data were collected by distributing questionnaire to a sample of 450 individuals selected at random using the accidental technique. A close ended questionnaire was used and the questionnaire captured individual characteristics and views on the use of mobile phone. The questionnaire was administered over a period of twelve weeks. Many and very significant conclusions are derived from this research. It has been found that the majority of respondents use the mobile phone; the main reason for having a mobile is because they want to have it; the most important reason for having a mobile phone is to easily communicate with friends or relatives; the main purpose of using mobile phone sets always are making local calls. It is also interesting to note that some respondents never used their mobile for sending text messages; perhaps this is related with the illiteracy rate in the country. The findings show that certain variables such as gender and income are important predicators of mobile usage in Eritrea. The empirical results show that age and educational level were not significant in explaining variations among mobile users.
The objective of this paper is to determine what factors stimulate or hinder the adoption and usage of the Internet by analyzing data collected from 300 respondents from the city of Asmara, Eritrea in the year 2017. We adopted a micro-econometric approach (Multinomial logit model -MNL) and the paper identifies six significant determinants and estimated their impact with the help of econometric tests. The results show that internet users in the city of Asmara tend to be young and in better living conditions. The probability of using the Internet is also higher for people with better English ability and for individuals’ who have better computer savvy. Moreover, Internet users are more likely to have close family members and friends who also use the internet. These results provide evidence of not only digital divide in the Internet access, but also in the usage patterns in the city.
