Theory Analysis of Model for Price Fluctuations in a Single Commodity Market

The price model for a single commodity market is a very important economic model that describes the basic rules for price fluctuations in a single commodity market. In this paper, we investigated the general case for the model, and proved that every positive solution is bounded and we obtained a necessary and sufficient condition for oscillation of every positive solution concerning positive state solution.

The price relationship between organic and non-organic vegetables in the U.S.: evidence from Nielsen scanner data

This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability.     

由临街地价推算区片价的方法探讨

如何利用临街样点地价推算区片平均地价及基准地价始终是城镇基准地价评估的一个难点。文章利用赤峰市的实际调查数据,分别采用临街贡献率和面积加权两种方法推算区片平均地价,并采用回归分析方法探讨区片价与临街地价之间的关系,结果证明两种方法所推算的区片平均价是基本一致的,而且区片价与临街地价之间呈“反S”曲线关系。     

Strategic Firm Behavior Under Average-Revenue-Lagged Regulation

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions.     

不同地区低保标准比较的参照基准研究

为了适应社会主义市场经济稳定发展的需要,各地区陆续实行了城镇居民最低生活保障金制度。但因各地区经济发展水平、物价指数以及消费习惯等原因,保障金水平差异较大。对各地区“低保”标准合理性作比较时,往往缺乏一个较为客观的参照基准。根据各地区城镇居民家庭平均月支出水平与恩格尔系数之间的关系创建了最低生活保障参照基准LSBi和最低生活保障参照系数LSCi,并对选定的一批样本城市的实际低保水平作了验证与比较,具有可操作性。

Investor efficiency in the face of takings

Governmental entities at all levels are empowered to acquire private property for the public's benefit, provided that just compensation is paid. The level of compensation typically viewed by courts as just is market value, but questions arise as to whether market value compensation motivates the private owner of land, potentially subject to a taking, to improve the property to a degree that is socially efficient. Earlier works have found market value to be a compensation level too high to promote efficiency. The present paper offers an analysis, based on a simple model of investor profit maximization, that provides a unified view of models presented in some important earlier works. In a special application of the general case, it is shown that market value can be too low a level of compensation to promote efficient behavior by the land owner.
