Information asymmetry and the speed of adjustment: debasements in the mid‐sixteenth century

This article examines the impact of information asymmetry on the movement of London–Antwerp exchange rates against the backdrop of the Great Debasement of 1544–51. The case of the revaluation of gold coins in the Habsburg Netherlands in 1539, about which the sovereign and the public possessed similar information, is used as the benchmark to judge how far the speed of adjustment was affected by information asymmetry. This article is also part of the recent literature that estimates the degree of financial market integration in late medieval and early modern Europe. In the framework of the threshold autoregressive model, the speed of adjustment and the transaction costs associated with arbitrage are estimated, and the results are judged using the speed of communication as a benchmark since the flow of information played a critical role in financial arbitrage. The results reveal that the sixteenth‐century London–Antwerp exchange markets were already as integrated as that during the late nineteenth century, but information asymmetry severely disturbed the effectiveness of exchange arbitrage.     

旅游中的文化生产与文化消费

一、文化与旅游的讨论:日常生活与消费的视角随着20世纪80年代以来的"文化转向",社会科学开始研究经济领域中的社会文化变化和文化理论,文化研究因而被引入多种学科的讨论中,包括旅游。早期对于文化与旅游的关系的讨论充满了张力,比如认为当文化价值为了游客便利消费的需要而被商品化为旅游产品时,其文化价值或是被削弱,或是被破坏了。     

Selective disclosure and the role of Form 8-K in the post-Reg FD era

We investigate the impact of Form 8-K filings on cross-firm differences in analysts’ private or idiosyncratic information in the post-Reg FD era. Using firms’ connections to the investment community to identify the likelihood of selective disclosure, we document differences in analysts’ idiosyncratic information arising from selective disclosure before 8-K filings. While filings of 8-Ks pursuant to Reg FD attenuate the link between connections and analysts’ idiosyncratic information, they do so only after selective disclosures have already resulted in some analysts having better private information. In addition, the connections continue to facilitate private information search after the filings of non-Reg FD-specific 8-Ks.     

The Valuation Model for a Risky Asset When Its Risky Factors Follow Gamma Distributions

This paper constructed a pricing model for the asset with multi‐risks by specifying the risky factors (i.e., interest rate and termination hazard rates) to follow gamma distributions. The model not only avoids the possibility of the termination hazard rate taking an irrational (i.e., negative) value, but it also makes it easier to derive a valuation formula for a risky asset. Our model can also effortless apply because the parameters of the gamma distribution can easily be estimated from market data. An example using Taiwanese bond data illustrates how the model can be utilized for practical applications. To facilitate understanding of how accurately the different models price risky bonds, we compare their out‐of‐sample pricing errors for different hazard rate specifications assuming normal and gamma distributions. The results show that our pricing formula is realistic and accurate in its applications. Therefore, it should help market participants to accurately price risky assets and to effectively manage complicated portfolios.     

基于NETSTARS运用定床水理原理在河道疏浚中的应用

疏浚大多用于河道的过分淤积,拓宽则用于通水隘口的消除。而随着时空的演变河床疏浚与河槽拓宽的进行所需考虑的因子越来越多,故疏浚进行前应尽量考量整个河道的河性以及施工后可能引致的变动,使能维持预期的效果,并避免造成负面效应。本文主要以涧河为研究对象,利用NETSTARS拟似二维水理输砂模式,探讨河道疏浚后的水理与输砂演变趋势等相关课题。     

涉农贷款中新担保措施的合法性及有效性分析

为防范涉农贷款违约风险,部分农村信用联社积极探索,创新出债权文书公证方式、以人身险保险金担保债权等担保方式,以确保债权得到切实维护.这些新担保方式一定程度上增加了农村贷款供给,但存在法律风险.本文着重对这些新措施、新方法的合法性及有效性进行了探讨.
