Price and Volatility Transmission and Market Power in the German Fresh Pork Supply Chain

We investigate the relationship between the transmission of price volatility and market power in the German fresh pork supply chain. We use a theoretical model underpinning this relationship followed by an empirical application that uses monthly farm, slaughterhouse and retail pork price data for the period 2000–2011. We examine both the relationships of market power with price level transmission and price volatility transmission in the chain. We use a vector error correction model and least squares regressions to analyse price transmission and price volatility transmissions, respectively. Results show that retail market power limited both types of transmissions. Competition inducing policy measures coupled with measures that support price risk management initiatives of chain actors are suggested.     

Do the EU countries import at the same price? The case of coffee

The establishment of the Economic and Monetary Union was expected to determine price convergence in the market of the European Union, leading to the equilibrium theorized by the law of one price. This article investigates prices convergence in the coffee market among European importers. Coffee is not only a tradable and traded good, but also one of the most valuable traded commodities. We account for different qualities of coffee in a hedonic regression model, which isolate and remove the effects of factors that might affect price dispersion. Adjusted import prices result to be significantly different between European Member States, and do not support the hypothesis of a deepening European market integration.     

城市经营者还是市场监管者？——市场波动下地方政府土地供给非对称行为研究

研究目的:分析市场监管激励对于地方政府土地供给决策的影响。研究方法:通过建立模型对市场监管激励的影响机制进行理论分析,并基于2004—2014年中国30个省的面板数据构建门限模型进行实证检验。研究结果:地方政府的土地供给决策同时受到经济绩效和市场监管双重激励的影响,在不同的市场波动下存在非对称性:在市场较平稳时,地方政府会通过减少土地供给、提升土地价格实现其经济绩效目标;而在市场波动较大时,地方政府则会兼顾"市场监管者"的职责,通过增加土地有效供应、维持土地价格实现其经济绩效目标。研究结论:市场监管激励在地方政府的土地供给决策机制中具有显著作用,可以通过加强政绩考核中市场监管的权重来规范地方政府的土地供给行为。     

多市场接触与市场竞争行为——以中国民航运输业为例

多市场接触竞争理论考虑了同一企业在不同市场的竞争行为的关联性,大量来自西方市场的研究证明多市场接触可导致企业在竞争中"相互容忍",降低市场竞争的激烈程度.参照这些研究方法,本文运用中国国内主要定期航线市场数据,计算出航线多市场接触指数,并进行回归分析.结果显示,尽管中国国内航线市场多市场接触程度较高,但对市场竞争的实际影响微弱.研究还发现管制制度是影响中国航空公司竞争战略的重要因素.

Impacts of Market Reform on Spatial Volatility of Maize Prices in Tanzania

Maize is one of the major staples and cash crops for many Tanzanians. Excessive volatility of maize prices destabilises farm income in maize‐growing regions and is likely to jeopardise nutrition and investment in many poor rural communities. This study investigates whether market reform policies in Tanzania have increased the volatility of maize prices, and identifies regional characteristics that can be attributed to the spatial price volatility. To achieve the objectives, an autoregressive conditional heteroskedasticity in mean (ARCH‐M) model is developed and estimated in this study. Results show that the reforms have increased farm‐gate prices and overall price volatility. Maize prices are lower in surplus and less developed regions than those in deficit and developed regions. Results also show that the developed and maize‐deficit regions, and regions bordering other countries have experienced less volatile prices than less developed, maize‐surplus and non‐bordering regions. Our findings indicate that investments in communication and transportation infrastructures from government and donor countries are likely to increase inter‐regional and international trade, thereby reducing the spatial price volatility in Tanzanian maize prices in the long run.     

从福州市民对旅游服务业的认知谈本地旅游市场的开发

城市居民作为城市旅游服务业体系中的一大组成部分,如酒店的当地居民消费、居民的周边旅游等等。在城市的旅游开发中,需要充分考虑到当地居民的需求,这不但有助于提高旅游业的综合效益,也能大大造福于城市居民,所以,研究城市居民对当地旅游服务业的认知,与研究外来旅游者对当地旅游服务业的认知对于政府,旅游企业及相关部门的决策具有同等重要的意义,以福州市为例进行了服务认知研究,并提出了福州市开发本地居民旅游市场的一些建议。
