The study utilizes a structural VAR model to understand the connections among oil shocks, policy uncertainty and aggregate earnings in US. We find that the positive innovations in US oil supply increase the aggregate earnings. A rise in the US policy uncertainty decreases the aggregate earnings. After 2007 with the shale oil development in US, the earnings responses to the US oil supply shocks has increased. Over time shocks to US oil supply reduce the policy uncertainty. The development of US oil production is associated with the increase in income and the enhancement on political and economy security in US. Policy uncertainty plays an important role in the transmission of oil shocks to the earnings. The structural oil price shocks explain around 35% of the overall variations in the policy uncertainty in the long run and cause long swings in the policy uncertainty. The direct effects of oil shocks on the aggregate earnings are amplified by the endogenous responses of policy uncertainty. 相似文献

We find that firm value is reduced via industrial diversification and this reduction in value depends upon a firm’s technology intensity. We consider that asymmetric information problems are more severe in technology intensive industries and find that high tech industry firms present distinctly larger value reduction when compared to low tech industry firms. The negative valuation effect is greater for firms that have a relatively larger amount of intangible assets and greater R&D capital. We determine that our findings are robust to different estimation methods and alternative excess value measures. 相似文献

A plethora of governance measures has been developed to assess governance capacity in different countries. Choosing one indicator over another involves discretionary decision issues. This article presents a new unified measure of governance capacity for the administrative and political dimensions. The unified measure provides a more accurate understanding of governance than single indices. 相似文献

This article investigates the patterns of vertical specialization in trade among China, Japan and Korea, and the effects of real exchange rate fluctuations under a multistage production process. By extending the models of Yi (2003, 2010), we derive two distinct features of vertical specialization and test them using Time-Varying Parameter (TVP) VAR. We find that a positive shock to China’s final good consumption increases the intermediate goods trade between Korea and China, with expanding magnitude over time. In addition, the positive effect of a real exchange rate depreciation on intermediate goods trade is strengthened through the competitiveness-enhancing channel, with this effect being more pronouncing in Korea-China trade than in Korea-Japan trade. 相似文献

The article examines the structural changes of China’s import market for domestic demand and the corresponding structural changes of Korea’s exports to China for Chinese domestic demand. Using 8-digit HS code data covering the period 2006–2014 and analyzing the processing steps as well as by industry, this study reveals that while the share of ordinary trade in total China’s imports has increased rapidly, the share of processing trade has decreased continuously since the mid-2000s. The article also shows that Korea’s exports to China is still processing trade-oriented. The slowdown of Korea’s exports to China is because of the concentration on processing trade, intermediate goods, electronics and chemistry. 相似文献

Drawing on reversal theory (Apter, 2007), the current research proposes that internet users' metamotivational state (telic vs. paratelic) determines advertising interactivity's effectiveness. An online field experiment involving 141 Facebook and Twitter users tests this proposition. Research findings support telic state consumers form more positive attitudes toward a low-level interactive ad, whereas paratelic state consumers form more positive attitudes toward a high-level interactive ad. Further, this research shows that an arousal seeking tendency mediates the metamotivational state's impact on ad attitude. 相似文献

Do analysts who understand accounting conservatism exhibit better forecasting performance? 下载免费PDF全文

This study investigates the performance of analysts when they match the asymmetric timeliness of their earnings forecast revisions (i.e., asymmetric forecast timeliness) with the asymmetric timeliness of firms’ reported earnings (i.e., asymmetric earnings timeliness). We find that better timeliness‐matching analysts produce more accurate earnings forecasts and elicit stronger market reactions to their forecast revisions. Further, better timeliness‐matching analysts issue less biased earnings forecasts, more profitable stock recommendations and have more favorable career outcomes. Overall, our results indicate that analysts’ ability to incorporate conditional conservatism into their earnings forecasts is an important reflection of analyst expertise and professional success. 相似文献

Virtual consumption involves consuming virtual goods in cyberspace. Virtual consumption activities are evolving into an essential activity in social virtual worlds. Despite the growing importance of this activity, little research examines this phenomenon. The current study investigates the fundamental question of how users understand the consumption of virtual goods. Using the theory of social representations and core-periphery analysis, this study elicits and analyzes the social representation of virtual consumption. Study participants are 154 Second Life users. Results identify 32 concepts and relationships representing the collective perceptions of virtual consumption in this social virtual world. Social representation map interpretations point to several key themes that provide a foundation for future investigations of virtual economy consumption behavior. 相似文献
