Public bicycle as a feeder mode to rail transit in China: The role of gender,age, income,trip purpose,and bicycle theft experience

A marriage between public bicycle and rail transit presents new opportunities for sustainable transportation in Chinese cities. To examine determinants of public bicycle usage for rail transit access, an intercept survey of feeder mode choice among rail transit users was conducted near rail stations in Nanjing, China. Mode choice models were estimated with five feeder mode alternatives, including car, bus, walk, private bike, and public bike. By differentiating between public and private bicycle modes in the mode choice models, the study reveals the effects of personal demographics, trip characteristics, and station environments on public bicycle usage for rail transit access. Results show that female, older, and low-income rail commuters are less likely to use public bicycle to access rail transit. Rail commuters with bicycle theft experience and making school- or work-related trips are more likely to use public bicycle to access rail transit. Land use variables are largely insignificant in this study except that density shows a positive relationship with walking to rail transit. The results on demographic differences raise equity concerns when it comes to investing in public bicycle systems. Policy implications are discussed for Chinese cities to equitably boost public bicycle integration with rail transit.     

青海地区农业保险保单质押模式的探索——以青海藏区为例

欠发达地区多以农牧业发展为主，农牧民融资问题一直是阻碍这些地区生产发展的一大障碍。针对这种情况，本文提出了以保单质押摸式来解决融资问题。保单质押是以未来预产出的农业产品作为对象进行风险投保，然后通过保单资本化进行抵押贷款的融资方法。这种方法一则解决了抵押物缺乏的融资困境；二则引入了保险机制对农牧业风险进行合理规避，进一步确保了贷出资金的回收能力。与此同时，政府可做好配套工作，促进农业保险保单抵押贷款工作的开展，如此一来，农牧民融资问题可以得到很大程度的解决。

论农村闲置宅基地与农房收储的制度构建

农村闲置宅基地与农房收储制度是全面推进乡村振兴背景下盘活利用闲置宅基地与农房的前提和基础.目前,在深化宅基地制度改革中,仅有少数地区进行了探索,尚未形成系统的收储制度.闲置宅基地与农房收储的实践探索主要分为村集体主导和政府主导两种模式.闲置宅基地与农房收储制度应从制定收储指导意见、设置管理模式及机构、明确收储条件和补偿标准、强化收储资金保障、健全收储程序、完善收储监管与责任等方面进行系统构建.闲置宅基地与农房收储后可通过复垦复耕统筹使用,纳入集体经营性建设用地并入市流转,发展休闲农业和乡村旅游产业,兴办厂房、仓储或发展特色产业等路径,激活"沉睡"闲置的宅基地与农房,实现宅基地与农房由资产到资金的蜕变.     

Inferring information from the S&P 500, CBOE VIX,and CBOE SKEW indices

This paper compares the information extracted from the S&P 500, CBOE VIX, and CBOE SKEW indices for the S&P 500 index option pricing. Based on our empirical analysis, VIX is a very informative index for option prices. Whether adding the SKEW or the VIX term structure can improve the option pricing performance depends on the model we choose. Roughly speaking, the VIX term structure is informative for some models, while the SKEW is very noisy and does not contain much important information for option prices. This paper also extends Zhang et al. (2017, J Futures Markets, 37, 211–237) into three typical affine models.     

Does individualistic culture impact operational risk?

Employing a sample of 2,957 operational‐risk events across 31 countries from 1990 to 2011, we find that financial institutions located in countries with higher individualism tend to have higher operational risk. This positive relation is achieved through the risk‐taking channel and the earnings‐management channel. In addition, the magnitude of operational losses is higher in more individualistic countries. The results suggest that individualism serves as an important informal institutional determinant of operational risk in an international context. Endogeneity tests and various robustness checks confirm our findings.     

Valuation of VIX and target volatility options with affine GARCH models

In this paper we propose semiclosed-form solutions, subject to an inversion of the Fourier transform, for the price of VIX options and target volatility options under affine GARCH models based on Gaussian and Inverse Gaussian distributions. We illustrate the advantage of the proposed analytic expressions by comparing them with those obtained from benchmark Monte–Carlo simulations. The empirical performance of the two affine GARCH models is tested using different calibration exercises based on historical returns and market quotes on VIX and SPX options.

Determinants of the Method of Payment in Asset Sell‐Off Transactions

Using a sample of asset sell‐off transactions from January 1990 to April 2010, we find that the method of payment used in asset sell‐off transactions is associated with several characteristics cited in the acquisitions research that reflect cash constraints of the bidder. Specifically, bidders facing more stringent cash constraints are more likely to use equity when purchasing assets, while sellers subjected to cash constraints prefer cash when selling assets. Second, we find that the variation in method of payment among asset sell‐off transactions also is partially explained by variables representing asymmetric information. Third, we apply our model to an expanded sample that includes non‐U.S. sellers of assets and find that an equity payment is more likely when sellers are based in countries that have relatively high country risk (more government restrictions), weak shareholder rights, and a weak legal system. Thus, it appears that bidders prefer that sellers share in the risk of the transaction under these conditions.
