Do the determinants of service and pricing on “regional” routes – linking towns and smaller cities to main trunk routes and/or to each other – differ from the established results from the literature? We study all flights (about 3000) on all regional routes (about 250) with scheduled airline service from one of about 130 regional towns or cities, in regional airline markets in six countries: Australia, Canada, New Zealand, Norway, Sweden, and a sample of three U.S. states which closely resemble the other regions studied. For each flight we have observations on up to five prices offered at different times before flight date. We also have equipment type and social-economic data. Overall, our results give qualified support to the standard gravity model of the extent of service between city pairs, though with two interesting differences: operators on regional routes have greater flexibility in the size of aircraft they can deploy, which results in a finer-grained variability of service offerings and, the presence of competition on regional routes has a large effect on the total supply of seats. We are able to successfully estimate a well-specified airfare model, which shows strong effects of competition on prices, quite substantial intertemporal price discrimination, and interesting differences between regional and main trunk route pricing. 相似文献

随着现代经济的发展,石油与金融的结合越来越紧,石油金融化趋势日益凸显。因此,为应对国际石油价格的未来走势,保障中国金融体系和中国经济的安全和长期稳定发展,中国迫切需要制定石油金融体系。新形势下中国石油金融体系构建的战略取向为:多层次构建石油交易市场体系;多渠道营造石油银行系统;多途径形成石油基金组合;多方位灵活运用石油外汇等。 相似文献

失地农民再就业一直是党和政府着力解决的"三农"问题之一。从消除制度缺陷、提供培训资金支持、拓宽非农产业就业渠道、搞好就业培训等方面采取的措施尚未见到实效。失地农民再就业受到收入水平、生活成本、工作环境、技能要求、地区经济发展等因素的影响,政府应当在注重产业布局和调整的同时适度保留劳动密集型产业、加大公共财政保障力度,强化用人单位培训责任、系统设计失地农民权益保障制度等方面入手,破解失地农民"被城市化"后的再就业困境。 相似文献

This paper examines price differentials of identical items across retail channels. Many consumer packaged goods are sold through both grocery and drug stores. Liquor is unique in that in much of the country there is a third retail channel of distribution, liquor stores. If consumers in each retail channel differ in their willingness to pay for certain items, then sellers can exploit those differences and charge different prices for the same items in each channel. We examine a unique data set of pooled cross sectional retail scanner data on wine to test whether sellers use retail channel to identify heterogeneous consumer market segments and engage in price discrimination. We begin by presenting a model of price discrimination by retail channel along with behavioural assumptions regarding shoppers in each channel. Next we examine sales by retail channel and find persistent price differentials for the same item across retail channel after controlling for sample selection bias and seasonality. Lastly, we estimate the price elasticity of demand correcting for endogeneity and find differences across channel consistent with the price differentials. The extent of price differential, however, differs significantly with respect to price point. 相似文献

In this paper, we examine the role of stock liquidity as a governance mechanism to discipline managers for withholding bad news (stock price crash-risk). This topic is useful to emerging markets because the dominance of controlling owners limits the monitoring of internal governance. Stock liquidity can be altered by the financial market regulations, thereby improving firm-level governance. In empirical analysis, we show that stock liquidity decreases stock price crash-risk. We identify two possible mechanisms through which stock liquidity reduces stock price crash-risk: the threat of intervention and price informativeness. 相似文献

The quality perception of a new brand improves when it is bundled with a product having a strong brand image, moderated by the level of complementarity between the bundle components. This study takes this research forward with the help of two experiments. The first experiment uses anchoring and adjustment process to conclude that the quality perception of a new brand further strengthens if bundled with a strong brand of a higher price category than itself. The second experiment concludes that the quality perception of the strong brand can also deter if bundled with a new product of uncertain quality. 相似文献

We develop an arbitrage‐free valuation framework for bilateral counterparty risk, where collateral is included with possible rehypothecation. We show that the adjustment is given by the sum of two option payoff terms, where each term depends on the netted exposure, i.e., the difference between the on‐default exposure and the predefault collateral account. We then specialize our analysis to credit default swaps (CDS) as underlying portfolios, and construct a numerical scheme to evaluate the adjustment under a doubly stochastic default framework. In particular, we show that for CDS contracts a perfect collateralization cannot be achieved, even under continuous collateralization, if the reference entity’s and counterparty’s default times are dependent. The impact of rehypothecation, collateral margining frequency, and default correlation‐induced contagion is illustrated with numerical examples. 相似文献

本文利用1997-2013年中国省际层面的面板数据,借助异质性动态调整模型从动态视角考察了地方财政行为对中国贸易收支调整速度的影响。研究结果显示:(1)平均而言,在地方财政行为的驱动下,中国实际贸易收支向最优水平动态调整的速度约为0045。总体表明,地方财政行为对中国贸易收支的驱动性影响较弱,引致实际贸易收支向最优水平调整的速度也较为缓慢。(2)财政支出分权的强化会制约贸易收支的调整速度,贸易收支调整呈现“相对惰性”。财政收入分权的提高和预算内财政支出的扩张能够加快实际贸易收支向最优贸易收支调整的速度,助力贸易收支实现平滑调整。预算外财政支出和财政收入的变化对调整速度则不会产生显著性影响。(3)贸易收支的调整速度呈现显著的区域异质性。本文的结论表明,现阶段中国要实现贸易收支的平衡调整路径,中央及地方政府必须把握好财政行为与贸易收支的动态联动关系。 相似文献

The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of investment), and earn higher expected stock returns than losers. The investment model succeeds in capturing average momentum profits, reversal of momentum in long horizons, long-run risks in momentum, and the interaction of momentum with several firm characteristics. However, the model fails to reproduce the procyclicality of momentum as well as its negative interaction with book-to-market equity. 相似文献
