关于商品价值、生产价格及其售卖价格公式量化的探讨

传统的商品价值公式C V m,只能理解为商品在生产领域所形成的价值,而不能理解为是商品价格因供求变化围绕其价值中枢上下波动的那个商品价值.真正的商品价值,应既包括商品的生产价值,又包括商品的流通价值.因为,在流通领域中的保管、运输劳动也是创造价值的劳动;同时,纯粹商业劳动亦是创造价值的劳动.依据这一思路,生产价格应改为"生产--流通价格"或"商品平均价格".

基于机构投资者非理性报价的IPO定价分析

本文主要研究机构投资者非理性报价行为。在发行人(发行人与承销商的统称)理性假设下,建立模型并研究了机构给出不同价值信号时的发行价格设定与机构获配情况。文中分析发现当机构投资者拥有好的价值信息时,发行人的报价约束是有效的;当其拥有不好的价值信息时,报价约束完全不起作用,机构投资者会蓄意传达无价值或是好的信号,造成新股价格高于其价值。

我国航空运输服务业的市场结构及价格竞争策略分析

我国航空运输服务业从宏观上分析具有寡头垄断的市场结构特点,从航线运营的角度分析却具有垄断竞争的特点,因此我国航空运输服务市场还处在重要的发展变革阶段。在我国空运市场特定的经济环境下,旅客的购买决策受到多种因素的影响,航空公司的价格竞争主要表现为不同价格的子舱位数量的决策,并且具有复杂的价格体系。在同一航线上经营的不同企业一方面要针对价格需求弹性大和时间需求弹性大的旅客采取强硬的价格竞争策略;另一方面也要注重差异化价格竞争策略, 避免恶性竞争的发生。     

Land price diffusion across borders – the case of Germany

ABSTRACT

Land market regulations are often justified by the assumption that activities of foreign and non-agricultural investors drive up prices in domestic land markets. However, empirical knowledge about the dynamics of agricultural land prices across borders is sparse. Using the German reunification as a natural experiment, we study the effect of the former inner German border on the dynamics of agricultural land prices in East and West Germany. We apply a land price diffusion model with an error correction specification to analyse spatial agricultural land markets. A novel feature of our model is its ability to distinguish price diffusion within states and across state borders. We provide evidence for a persistent border effect given that the fraction of spatially integrated counties is larger within states than across the former border. Moreover, we observe non-significant error correction terms for many counties along the former border. From a policy perspective, it is striking to realize that even 25 years after German reunification, pronounced land price differences persist. It is quite likely that price diffusion through existing borders within the EU would take even more time given language barriers, different institutional frameworks, and information asymmetries between domestic and foreign market participants.     

Relationship between oil,stock prices and exchange rates: A vine copula based GARCH method

In this paper, we apply a vine copula approach to investigate the dynamic relationship between energy, stock and currency markets. Dependence modeling using vine copulas offers a greater flexibility and permits the modeling of complex dependency patterns for high-dimensional distributions. Using a sample of more than 10 years of daily return observations of the WTI crude oil, the Dow Jones Industrial average stock index and the trade weighted US dollar index returns, we find evidence of a significant and symmetric relationship between these variables. Considering different sample periods show that the dynamic of the relationship between returns is not constant over time. Our results indicate also that the dependence structure is highly affected by the financial crisis and Great Recession, over 2007–2009. Finally, there is evidence to suggest that the application of the vine copula model improves the accuracy of VaR estimates, compared to traditional approaches.
