Airline Code-share Alliances and Costs: Imposing Concavity on Translog Cost Function Estimation

This paper provides an assessment of how airline code-share alliances affect the costs of the airline industry. It makes two contributions to the literature. First, it measures the effects of airline alliances by estimating a translog cost function using a panel dataset of 10 major U.S.-based airlines over 29 quarters. Secondly, it ensures concavity of the estimated cost function by using the procedure suggested by Ryan and Wales (2000, Economics Letters 67, 253–260). A conventional translog cost function is first estimated and scale estimates are computed. Unfortunately, the estimated function fails the curvature requirement, which makes interpreting the estimated effects of alliances somewhat dubious. Hence, we re-estimate the cost function by imposing local concavity restrictions. We find that large alliance partners have a small negative effect on airlines costs, but small alliance partners effect on costs appear to be positive, although the magnitude is negligible. We also find material differences in the estimates of scale economies after imposing local concavity.JEL classification: L00, L12, L93     

Acquisition valuations of withdrawn IPOs: When IPO plans turn into mergers

We examine the acquisition valuations of withdrawn-IPOs – private targets that are acquired after they file and then withdraw their IPOs – to examine how IPO registration and withdrawal affect valuations of withdrawn-IPOs in their subsequent mergers. We find that these “almost public” withdrawn-IPOs sell at a significant acquisition premium relative to comparable pure private targets that never file IPO registration and at acquisition valuations similar to comparable public targets. The premium persists only for withdrawn-IPOs that are acquired before their IPO withdrawals after other factors are controlled for. These findings confirm that there is a significantly positive (negative) valuation impact of IPO registration (IPO withdrawal) on withdrawn-IPOs’ subsequent acquisitions. The two effects offset each other for withdrawn-IPOs that are acquired after their IPO withdrawals.

近年来,作为宏观调控手段的关税政策被越来越多地运用,同时在金融危机形势下刺激出口、刺激国内经济复苏方面也有着积极的意义。本文从我国关税的起源和发展写起,基于关税内生化理论下分析我国关税的发展,最后提出了进一步完善我国关税的对策。     

西藏经济增长趋势的因子分析研究

本文利用1991～2008年西藏的统计数据资料,采用因子分析法对西藏经济增长基本情况进行了实证分析。结果表明,当前西藏经济增长主要还是依靠投入,经济结构调整虽取得一定成效,但对促进经济增长影响程度不高。而产业结构调整对西藏经济增长的影响甚微,据此提出了相应发展对策。     

中西人本管理比较

本文通过对中西方人本管理的起源和主要理论观点的梳理比较,提出转型期中国传统人本管理需要进行现代转换,这种现代转换体现着人本管理与中国具体的社会发展阶段相适应的基本原则,科学精神与人文情怀的统一应成为现代人本管理理论建构的重要条件。     

美元周期性波动对我国跨境资本流动的非对称效应研究

有效应对和防范跨境资本流动冲击，维护外汇市场稳定是贯彻落实习总书记“打好防范化解重大风险攻坚战”的重要举措。目前，美元已进入强周期，我国正面临着由强势美元引发的货币贬值、资本外流等风险，当前背景下研究美元周期性波动特征、区制划分及其对跨境资本流动的影响具有重要的理论和现实意义。本文基于2006年10月至2018年6月的月度数据，运用理论模型和MSVAR模型分析美元周期性波动对我国跨境资本流动的非对称效应。研究表明，中美利差对跨境资本流动的影响存在非对称效应，当投资者不存在恐慌避险情绪时，利差的变化将不会引起大规模的跨国资本流动。美元指数对跨境资本流动的冲击效应具有一定的时滞性，美元升值将引发跨境资本流出，且冲击效应持续时间明显长于利差冲击。VIX指数和人民币汇率对跨境资本流动影响较弱，但呈现非对称性特征。加息和缩表后美元升值对资本外流的推动作用明显强于加息和缩表前，表明第三轮强周期下美元升值对我国跨境资本流动的影响更大。     

Who is left behind? Exploring the characteristics of China's broadband non-adopting families

China has made significant progress in broadband development. As of September 2018, 95% of China's population was covered by 4G networks. However, our estimates show that nearly 30% of China's families did not use broadband that year. This study attempts to investigate the characteristics of China's broadband left-behind families. Overall, consistent with the findings for other countries, families with a lower socioeconomic status are more likely to be broadband non-adopters. In the information society, older, poorer, rural and less educated families are left behind. It is recommended that the Chinese government shift from a top-down investment-driven policy to a user-centered demand-driven policy to address the digital divide.
