Research on the Relationship between CPI and PPI Based on VEC Model  [PDF]
Shijun Li, Guoqiang Tang, Duancui Yang, Shixue Du
Open Journal of Statistics (OJS) , 2019, DOI: 10.4236/ojs.2019.92016
Abstract: By establishing the VEC model, the relationship between Consumer Price Index (CPI) and Producer Price Index (PPI) is explored by using Johansen cointegration test and impulse response function. The results show that there is a long-term equilibrium cointegration relationship between CPI and PPI. CPI has a certain impact on PPI. PPI also has a certain impact on CPI. PPI has a great impact on itself both in the long-term and short-term. The current CPI will be adversely affected by the previous CPI and the positive impact of the previous PPI. The current PPI will be positively affected by the previous phase of CPI and the previous phase of PPI.
Research on the Relationship between Entrepreneur Confidence Index and Producer Price Index Based on Quantile Granger Causality  [PDF]
Qiying Lao, Guoqiang Tang, Huifang Qu
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.610006
Abstract: This paper investigates the relationship between Entrepreneur Confidence Index and Producer Price Index (PPI) based on the mean and quantile Granger causality tests, using quarterly statistics data from 2005 to 2017. The results indicate that there is a unidirectional causality between entrepreneur confidence index and PPI index. At different quantile levels, entrepreneur confidence index of the previous period has different effects on the current PPI index. At lower quantiles, the causality from entrepreneur confidence index to PPI index is significant, while entrepreneur confidence index has little impact on PPI at higher quantiles. The estimates of \"\" at low quantiles are positive and significant. Therefore, improving entrepreneur investment confidence will have a certain positive impact on PPI.

Abstract: Managers of economic institutions should possess some criteria in the stock exchange so that they can evaluate their performance and economic plans. Criteria for performance evaluation accounting can be used for evaluating performance and economic plans. One of the main criteria for performance evaluation accounting is reported accounting profit or dividends. This criterion is one of the main indexes for evaluating managers’ performance, and it is also a main criterion for decision-making on approval or rejection of economic plans. This index is influenced by different factors such as price index, especially consumer price index and producer price index. In this paper, relationship between producer price index and consumer price index is investigated in accepted firms in Tehran stock exchange. Dicky- Fuller Test is used for time series reliability and Pearson correlation coefficient and Granger-causality tests are used for investigating the relationship between variables. Finally, it was concluded that consumer price index has an inverse correlation with dividend per share (first hypothesis), and producer price index has a direct correlation with dividend per share (second hypothesis).
Producers’ Preference for Price Instability?  [PDF]
Andrew Schmitz
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.810114
Abstract: The debate over whether producers prefer price instability to price stability continues, especially where policies are often endorsed that aim at generating stability. Such policies include the holding of agriculture commodity stocks by government to bring about price stability. But why would producers support such a policy given that producers prefer price instability, or do they? Oi argues that producers prefer price instability, which is opposite to the conclusion reached by Massell. In this paper, we take up the issue as to producers’ preference for price instability using the classic welfare economic framework used by Massell and Just et al. We develop a producer price expectation model that brings about price stability, which is possible without storage. We use this as the basis upon which to compare price stability to price instability. Our conclusion is that producers prefer price instability regardless of whether it is due to demand or supply shocks.
The Market Price Method and Economic Valuation of Biodiversity in Bauchi State, Nigeria
Adeyemi, A.,Dukku, S. J.,Gambo, M. J.,Kalu, J. U.
International Journal of Economic Development Research and Investment , 2012,
Abstract: This study adopts the survey design to examine the feasibility and reliability of value estimatesof the Market Price Method by applying it to Gubi Dam area in Bauchi State, Nigeria. The theoretical bases of economic valuation methods were also examined to clarify their premises, rationales and conditions under which they would be valid. Data were collected through interviews and focus group discussion conducted with the village heads, fishermen, fish sellers and consumers within Bauchi metropolis. From the data collected, about 18,140kg of fishes are harvested at the Gubi dam annually, generating N4,279,000,000 and N7,273,000 from wholesale and retail activities annually respectively. Also, 69,200kg of vegetable were harvested at the Gubi dam irrigation farm annually, generating N3,248,000 and N5,202,000 from wholesale and retail activities annually respectively. Among other things, the findings reveale that property rights related to ecosystems and their services are often not clearly defined, if property rights for natural resources are not clearly defined, they may be overused, because there is no incentive to conserve them. Using reasonable assumptions, the research concludes that the method proved to be applicable in the study area but needs to be improved upon, to make the value estimates credible and reliable in developing economies. Finally, it is recommended among things that the discounting of economic benefits should be made to reflect time value of money and that provisions for outgoings should be made to reflect elements of market failure in the method.
Democratic, Plutocratic and Social Weights in Price Indexes  [PDF]
Paolo Liberati
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25084
Abstract: This paper introduces social considerations into the calculation of the price index. To this purpose, recourse is made to the concept of distributional characteristic. It is shown how an aggregate price index can be expressed as a weighted average of commodity-specific prices, with weights that depend on both the aggregate share of consumption and the way in which consumption is distributed across households. The proposed index provides a complementary basis for the analysis of the impact of inflation and for the calculation of its social value.
Modeling Consumer Price Index in Zambia: A Comparative Study between Multicointegration and Arima Approach  [PDF]
Stanley Jere, Alick Banda, Rodgers Chilyabanyama, Edwin Moyo
Open Journal of Statistics (OJS) , 2019, DOI: 10.4236/ojs.2019.92018
Abstract: Consumer Price Index (CPI) is an important indicator used to determine inflation. The main objective of this research was to compare the forecasting ability of two time-series models using Zambia Monthly Consumer Price Index. We used monthly CPI data which were collected from January 2003 to December 2017. The models that were compared are the Autoregressive Integrated Moving average (ARIMA) model and Multicointegration (ECM) model. Results show that the ECM was the best fit model of CPI in Zambia since it showed smallest errors measures. Lastly, a forecast was done using the ECM and results show an average growth rate for food CPI at 6.63% and an average growth rate for nonfood CPI at 7.41%. Forecasting CPI is an important factor for any economy because it is essential in economic planning for the future. Hence, identifying a more accurate forecasting model is a major contribution to the development of Zambia.
The Virtual Repeat Sale Model for the House Price Index for New Building in China  [PDF]
Weihua Jin, Shengping Jin
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.521320
Abstract: By using the characteristics of the new building in China, this article constructs the virtual repeat sale method to produce virtual repeat data which is similar to the repeat sale model on the house price index. Case-Shiller procedure and OFHEO method are used to calculate the house price index for new building in China. A discussion is given and furthering models are needed to take advantage of the virtual repeat sale data.

Abstract: the purpose of this research is to analyze methodologies for calculation of price indexes for cargo freight in brazil. the study on the most used mathematical formulas has come to the conclusion that fisher and walsh indexes are those which comply with most of the logical, statistical and economic principles, followed by geometric indexes, such as t?rnqvist, vartia and theil. laspeyres and paasche, in spite of their limitations, are widely used in practical terms. a case study was selected to evaluate variations on possible procedures for index construction. four treatments have been conducted. as a result, we observed that the accumulated variation of the general price level for road transportation of soybean in brazil between february 1998 and march 2002 was 76%.
A Modified Consumer Price Index  [PDF]
Gonglin Yuan, Xiangrong Li
Modern Economy (ME) , 2010, DOI: 10.4236/me.2010.12011
Abstract: It is well known that the Consumer Price Index (CPI), as a Laspeyrestype index, attempts to measure the average change in the prices paid by urban consumers for a fixed market of goods and services, and new samples for most item categories are routinely introduced over time to keep the CPI sample representative of consumer spending patterns. The CPI normally overstates the true rate of increase of the cost of living. In this paper, our main objective is to propose a new measurement in the CPI which combines with the Gross Domestic Product (GDP). This new method will make the bias effectively decreased.
