The demand for eurozone stocks and bonds in a time-varying asset allocation framework

This paper analyzes the short and long-run demand for traditional financial asset classes in eleven founding eurozone members. Our sample period starts from the introduction of euro till 2017. We calculate the welfare losses stemming from ignoring the demand for domestic and eurozone equities and bonds, for various levels of risk aversion. Our results show that the bonds of eurozone countries are, in general, desirable for short-run only. However, in Ireland, Portugal and Spain the bonds are desirable for both short-run and long-run investment horizons. Stocks exhibit both short-run and long-run desirability for all countries except Greece. The Greek stocks are desirable for short- run only.

中国黄金与行业股票市场的动态相关性研究——基于DCC-GARCH模型

利用2015—2023年的黄金AU9999与十个上证行业指数日收益率数据,建立DCC-GARCH模型来分析动态相关性并计算最优投资权重和最优对冲比率。实证结果发现,黄金与行业股票市场存在动态相关性;黄金市场对十个行业的避险和对冲作用有差异,市场极端情况下黄金与行业指数均高度负相关,熊市期间黄金与原材料以外的九个行业具有不同程度负相关,黄金与工业、可选消费等七个行业长期具有负相关性;黄金平均权重在主要消费行业占比最高,原材料行业的对冲比率最高。最后提出资产组合纳入黄金、持续评估和区分行业进行风险管理的建议。     

股权分置改革相关会计处理探讨

本文对当前证券市场的热点问题———股权分置改革相关主体的会计处理进行探讨,认为,对于不同的股权分置解决方案,会计处理的实质应该一致。对于非流通股股东而言,对其支付对价或补偿应该作为股权投资的投资成本,对于采用权益法核算的非流通股股东应该重新确定股权投资差额;对于流通股股东而言,其所收到的对价或补偿应该作为投资成本的收回,符合谨慎性原则;对于上市公司而言,如果其承担了股改费用,则股改费用应该冲减股本溢价,而不能作为费用。     

The impact of stocks and flows of organizational knowledge on firm performance: an empirical investigation of the biotechnology industry

The knowledge‐based view of the firm is a recent approach to understanding the relationship between firm capabilities and firm performance. Specifically, this approach suggests that knowledge generation, accumulation and application may be the source of superior performance. Other research has conceptualized organizational knowledge in terms of stocks of accumulated knowledge in the firm and flows of knowledge into the firm. This paper tests the relationship between stocks and flows of organizational knowledge and firm performance in the biotechnology industry. We suggest that a firm’s geographic location, alliances with other institutions and organizations and R&D expenditures are representative of knowledge flows, while products in the pipeline, firm citations and patents are indicative of knowledge stocks. Through factor analysis, we develop an aggregated measure of location from several variables. A regression model suggests that location is a significant predictor of firm performance as are products in the pipeline and firm citations. A major contribution of this investigation is the operationalization of geographic location and its statistically significant link to firm performance. Copyright © 1999 John Wiley & Sons, Ltd.

Does microtherm boost pharmaceutical companies’ market capitalization returns?

The purpose of this study was to survey the relationship between the temperature factors and market capitalization returns of pharmaceutical companies by analysing both the daily and weekly frequency data in Taiwan. The threshold regression model with the GJR-GARCH process was applied for examination in this study; we found that pharmaceutical companies’ market capitalization returns could be boosted after exposure to extremely low temperatures for a period of time. Besides, the delayed effect of cold weather is demonstrated to exist. This phenomenon can be illustrated by epidemiological evidence-related mental factors, not by traditional behavioural finance. Moreover, lower weekly average temperatures are beneficial for investors to gain weekly pharmaceutical companies’ market capitalization returns. We are of the opinion that our findings offer an insightful suggestion for investors to buy pharmaceutical stocks at an opportune moment.     

The accounting identity trap: identification under stock-and-flow rank deficiency

Empirical research relying on inputs from published company financial statements ignore the fact that the observed accounting data matrix has been purposefully designed to be rank deficient by means of articulation between stocks and flows. This inherent feature of the data-generating process suggests structural non-identification when both stocks and flows appear in the design matrix and a constraint is required to identify parameters. Much financial research has fallen into this ‘accounting identity trap’ and routinely employs implicit constraints to enable estimation, albeit without acknowledgement of the constraints hence the misleading inferences. This article elucidates the problem of parameter identification under stock-and-flow rank deficiency using existing applications on equity pricing. The focus is on the interpretation of slope coefficients that must be anchored on economically defensible parameter constraints.     

EU Emission Allowances and the stock market: Evidence from the electricity industry

This paper constitutes - to our best knowledge - the first econometric analysis on stock market effects of the EU Emission Trading Scheme (EU ETS). Our results suggest that EU Emission Allowance (EUA) price developments matter to the stock performance of electricity firms: EUA price changes and stock returns of the most important European electricity corporations are shown to be positively related. This effect does not work asymmetrically, so that stock markets do not seem to react differently to EUA appreciations in comparison to depreciations. The carbon market effect is shown to be both time- and country-specific: It is particularly strong for the period of EUA market shock in early 2006, and differs with respect to the countries where the electricity corporations analysed are headquartered. Stock market reactions to EUA volatility could not be shown.     

Security analyst firm reputation and investors’ response to forecasted stocks in the biotechnology sector

ABSTRACT

Stock analyst reputation bridges the gap between technical knowledge of the high-technology and the investor's response to its stock, implying that the reputation of the stand-alone analyst serves this purpose. However, global firms have a stronger influence on their stock analysts than do small firms with 2 personnel. Does firm reputation affect the individual analyst and attract investor attention to forecasted stocks? Evidence from SAFs (security analyst firms) in the biotechnology sector supports this question and proposition. Four moderators (interactive predictors of organisational reputation) show positive correlations. They are the SAF's age, size, performance, and media coverage. These organisational level measures contribute to the institutional theory compared to the literature that focuses on the individual analyst without their organisations. In line with institutional theory, we make three explicit points. First, high uncertainty in the biotechnology sector turns investors to the organisational legitimacy and reputation of the analyst. Second, the organisational age, size, performance and media coverage of the security firm reduces uncertainty of the investor in the biotechnology sector. Third, the reputation of security firm flow to its individual analysts as well as from the individual analyst to the security firm. Thus, the organisational context matters in a social setting.
