宽松的环境政策能吸引更多的外商直接投资吗——基于中国工业省级面板数据的分析

利用我国1997~2009年的工业省级面板数据和动态面板GMM估计方法,考察了相对宽松的环境政策是否是吸引FDI的主要原因。研究发现,环境政策较宽松的地区能够吸引更多的外资流入,但这种影响并不大,所以,以降低环境标准、牺牲环境为代价来吸引FDI不是明智之举;与东、中部地区相比,西部在吸引FDI上处于明显劣势,这在一定程度上加剧了我国经济结构的失衡。     

To tell or not to tell? The roles of perceived norms and self‐consciousness in understanding consumers' willingness to recommend online secondhand apparel shopping

Secondhand apparel shopping resides in a domain characterized by used goods traditionally associated with financially marginalized consumers. Acknowledging the elusive psychological barriers associated with preowned apparel, this study explores mechanisms that facilitate consumers' willingness to recommend online secondhand apparel shopping. Results from three experimental studies and a cross‐sectional survey of online secondhand shoppers in the United States reveal that hedonic and ethical benefits influence recommendation behavior via perceived norms, whereas economic benefit directly influences consumers' willingness to recommend. Moderated mediation analyses further demonstrate that self‐consciousness alters the strength of the indirect effects, such that consumers with lower self‐consciousness displayed greater willingness to recommend compared to highly self‐conscious consumers. Findings contribute to a greater theoretical understanding of the roles perceived norms and self‐consciousness play in facilitating or inhibiting recommendation behavior in a context that implicitly involves self‐disclosure of one's secondhand purchase behavior. Managerial implications offer insights on salient benefits that can be leveraged to influence word‐of‐mouth recommendation.     

Does conglomeration really reduce credit risk?

I quantify the effects of conglomeration on credit risk by first computing theoretical default probabilities for conglomerates and their hypothetical stand‐alone counterparts and then mapping them into physical probabilities using a comprehensive database of corporate failures. Comparing the credit risk of conglomerates with that of hypothetical stand‐alone firms, I report significant reductions in the annual probability of default for small firms. My results support the proposition that managers can have a strong incentive to engage in conglomeration, even if it reduces shareholder value and show for which firms this is the case.     

Monetary policy matters: Evidence from new shocks data

The evidence suggests that monetary policy post 1988 became more forward-looking, invalidating the identifying assumptions in conventional methods of measuring monetary policy's effects, leading to spurious and unlikely results for this period. We propose a new identification scheme that uses factors extracted from Fed Funds futures to measure exogenous changes in policy. Using this shock series in a VAR, we recover the contractionary effect of monetary tightening on output. Moreover, we find that as much as half of the variability in output was driven by monetary policy shocks, and that there is a mild price puzzle.     

A State‐Price Volatility Index for China's Stock Market

This study derives a volatility index for China's stock market with similar properties to the Chicago Board Options Exchange Volatility Index (the ‘VIX’). A long‐term benchmark of historic volatility expectations is here presented for China from 1996 to 2011, called the ‘China‐ State‐Price Volatility (SPV)’. Construction of this index involves the use of SPV methodology, using implied volatility calculated from options on the Hang Seng China Enterprise Index (HSCEI). Historic open–high–low–close volatility on the Shanghai Composite Index (SHCI) is also used to extend the benchmark prior to the availability of HSCEI options data. The China‐SPV successfully forecasts realised volatility for the Shanghai Stock Exchange. It also serves as a ‘fear gauge’ in that it monitors daily movements of the SHCI in the same way that the VIX monitors the S&P 500 index (Whaley, 2009). The China‐SPV evidences an increasing relation with the US market in terms of the dynamic correlation of levels and changes with the VIX since 2004.     

An improved bootstrap test of stochastic dominance

We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap or subsampling. The method admits prospects involving infinite as well as finite dimensional unknown parameters, so that the variables are allowed to be residuals from nonparametric and semiparametric models. The proposed bootstrap tests have asymptotic sizes that are less than or equal to the nominal level uniformly over probabilities in the null hypothesis under regularity conditions. This paper also characterizes the set of probabilities so that the asymptotic size is exactly equal to the nominal level uniformly. As our simulation results show, these characteristics of our tests lead to an improved power property in general. The improvement stems from the design of the bootstrap test whose limiting behavior mimics the discontinuity of the original test’s limiting distribution.
