This article takes the cigarette marketing line in L region as the research object, and develops a monthly sales model that matches the actual situation and has guiding value. The monthly sales forecast is constrained by annual sales and experience, resulting in two main problems: low planning accuracy and large fluctuations in actual monthly sales, making modeling difficult. Through research, it has been found that the fluctuations between different years and the same month are relatively small compared to the annual fluctuations. Therefore, it has been decided to adopt three types of exponential smoothing models: simple equilibrium, Hote linearity, and Brownian trend to predict monthly sales. By comparing three models, the Hote linear model predicts results more accurately.","PeriodicalId":508163,"journal":{"name":"Journal of Economics and Public Finance","volume":"27 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141927352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The U.S. Household Liquid Non-Disinfectant Cleaner Market: A Competitive Profile","authors":"Y. Datta","doi":"10.22158/jepf.v10n3p1","DOIUrl":"https://doi.org/10.22158/jepf.v10n3p1","url":null,"abstract":"This is the nineteenth paper—and twentieth study--that follows the footsteps of nineteen studies that have tried to analyze the competitive profiles of U.S. consumer markets: Men’s Shaving Cream, Beer, Shampoo, Shredded/Grated Cheese, Refrigerated Orange Juice, Men’s Razor-Blades, Women’s Razor-Blades, Toothpaste, Canned Soup, Coffee, Potato Chips, Alkaline AA Battery, Facial Tissue, Toilet Paper, Paper Towel, Disposable Diapers, Sanitary Pads, Automatic-Dishwasher Detergent, and Hand-Dishwashing Detergent. Michael Porter associates high market share with cost leadership strategy, which is based on the idea of competing on a price that is lower than that of the competition.However, customer-perceived quality—not low cost—should be the underpinning of competitive strategy, because it is far more vital to long-term competitive position and profitability than any other factor. So, a superior alternative is to offer better quality vs. the competition.In most consumer markets, a business seeking market share leadership should try to serve the middle class by competing in the mid-price segment; and offering quality better than that of the competition: at a price somewhat higher to signify an image of quality, and to ensure that the strategy is both profitable and sustainable in the long run. The middle class is the socio-economic segment that represents about 40% of households in America.Quality, however, is a complex concept, consumers generally find difficult to understand. So, they often use relative price, and a brand’s reputation, as a symbol of quality.The U.S. Household Liquid Non-Disinfectant Cleaner market had retail sales of $381 million in 2008. It was by far the largest segment of the eleven-segment Household Cleaners market, which had 2008 retail sales of $1,747 million. We have focused our attention on the 24-40 Oz size because it was the most popular, constituting 46% sales of the former market.The Household Liquid Non-Disinfectant Cleaner market was highly competitive, with no dominant player. In 2008 it had 24 brands each with sales over $ 1 million.Using Hierarchical Cluster Analysis, we tested two hypotheses: (I) That the market leader is likely to compete in the mid-price segment, and that (II) Its unit price is likely to be higher than that of the nearest competition.For 2008--and 2007--the data supported both Hypothesis I and II, because the market leader, Formula 409, was a member of the mid-price segment, and its unit price was higher that of the runner-up, Fantastic, also a member of the same segment. We found that relative price was a strategic variable, as we have hypothesized.We also discovered four strategic groups in this market.A pattern is emerging in price-quality segmentation analysis. In thirteen studies—that exclude Men’s Razor-Blades, Women’s Razor-Blades, Coffee, Toilet Paper, Paper Towels, Disposable Diapers, and Sanitary Pads—the market leader was found to be a member of the mid-price segment, as we have hypothes","PeriodicalId":508163,"journal":{"name":"Journal of Economics and Public Finance","volume":"26 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Study on Urban-Rural Income Inequality in China—Based on VAR Model","authors":"Weiji Lu","doi":"10.22158/jepf.v10n1p67","DOIUrl":"https://doi.org/10.22158/jepf.v10n1p67","url":null,"abstract":"Wealth disparity is a complex issue that has plagued the world for many years. China’s economic development has achieved world-renowned results during the last 40 years. Over that time, the country has risen from extreme poverty to the world’s second-largest economy. Nevertheless, the significant wealth inequality accompanying it has also caused great concern. At the start of China’s reform and opening-up period, government officials tacitly approved of this uneven development and made plans to “drive the rich first to the rich later” in pursuit of economic development. Economic development aims to achieve shared prosperity, not to deprive the relatively poor of wealth. As a result, wealth disparity in China must be addressed. Based on the Kuznets hypothesis, the theory of urban-rural dual structure, and the current situation in China, this paper has evaluated the current wealth gap in China. Since 1978, Chinese households’ wealth accumulation has come from the income gap. Private property was not allowed to exist during China’s planned economy period (1949-1977). After the reform and opening up period (After 1978), income disparities between various industrial sectors led to an initial round of wealth accumulation for many Chinese citizens. The industrialisation process and urbanisation rate significantly impacted China’s economic modernisation and growth. Therefore, this paper has analysed the effects of several factors on income disparity in China. The examined factors were; economic development, the urbanisation rate, and the industrialisation process. Based on the theoretical analysis, this paper selected time series data from 1978 to 2021, including; per capita GDP, the per capita disposable income of urban and rural residents, the urban population to total population ratio, and industry contribution to the GDP. First, an analysis of the impact of economic development on income inequality was conducted using a static model. Then, a VAR model was built through ADF and PP testing, and an impulse response and variance analysis were conducted to explain the impact of various factors on the change rate of income inequality. The study results indicated that (1) Economic development has resulted in a significant increase in the income of urban and rural residents. However, urban residents have benefited more. Simultaneously, the income gap between urban and rural areas has grown significantly alongside economic expansion. (2) Urbanisation showed little effect on the income gap in the short term; however, it increased it in the long term. (3) Industrialisation reduced the short- and long-term income gap while increasing urbanisation.","PeriodicalId":508163,"journal":{"name":"Journal of Economics and Public Finance","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139623800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Special bonds have played a constructive role in stimulating fixed asset investment and infrastructure development, emerging as a pivotal financing mechanism for local governments. This study takes A province as a case study, compiling data on its bond issuance and employing the KMV model to calculate the anticipated default probability and overall default risk of A province's special bonds during 2023-2025. Furthermore, a comparative analysis is conducted with neighboring provinces such as C and B. The findings indicate that A province's government debt risk is generally manageable; however, there exists some level of default risk associated with special bonds. It should be noted that when considering refinancing bond issuance, the repayment of principal and interest on local government special bonds heavily relies on these refinancing instruments, temporarily reducing but not eliminating default risk. Finally, based on empirical analysis results, several policy recommendations are proposed to address the risks posed by local government debt.","PeriodicalId":508163,"journal":{"name":"Journal of Economics and Public Finance","volume":" 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139626336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were 452 participants in two studies online. The results show that the brand logos with complete (vs. incomplete) frames have higher safety (in Study 1). Moreover, the logos’ frames of complete (vs. incomplete) brands will generate the positive brand attitudes through increasing the consumers’ psychological perception of safety. For products with high safety attributes, consumers will have a higher evaluation of the brand logos with the complete frames, but there is no effect for products with less important safety attributes (in Study 2). This paper provides some guidance for the research of consumers’ psychological perceptions, and also broadens the scope of application of the conceptual metaphor.","PeriodicalId":508163,"journal":{"name":"Journal of Economics and Public Finance","volume":"51 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139445755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
