The effect of mandatory auditor assignment and non-audit service on audit fees: Evidence from Korea

In Korea, regulators could assign auditors to firms. We investigate the relationship among audit fees, mandatory auditor assignment, and the joint provision of non-audit and auditor services in Korea. We find that assigned auditors charge significantly higher audit fees than freely selected auditors. We also find that the joint provision of non-audit and audit services does intensify the relation between auditor assignment and audit fees. Combined with the results of other studies that have shown that firms audited by assigned auditors report smaller amounts of discretionary accruals than firms audited by freely selected auditors, our results suggest the possibility that mandatory auditor assignment may improve auditor independence.     

Does corporate diversification reduce value in high technology firms?

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.     

An Analysis of Trade Patterns and the Effects of the Real Exchange Rate Movements in East Asia

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.     

Structural Changes in China’s Import Market: A Comparison with Korea’s Exports to China

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.     

Do analysts who understand accounting conservatism exhibit better forecasting performance?

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.     

Does health insurance decrease health expenditure risk in developing countries? The case of China

This article studies the impact of health insurance on individual out‐of‐pocket health expenditures in China. Using China Health and Nutrition Survey data between 1991 and 2006, we apply two‐part and sample selection models to address issues caused by censored data and selection on unobservables. We find that, although the probability of accessing health care increases with the availability of health insurance, the level of out‐of‐pocket health expenditure decreases. Our results from a selection model with instrumental variables suggest that having health insurance reduces the expected out‐of‐pocket health expenditure of an individual by 29.42% unconditionally. Meanwhile, conditional on being subjected to positive health expenditure, health insurance helps reduce out‐of‐pocket spending by 44.38%. This beneficial effect of health insurance weakens over time, which may be attributable to increases in the coinsurance rates of health insurances in China.     

Open Innovation in Emerging Markets: A Business Model Perspective

There has been significant contribution to the management literature on open innovation and partnership strategy, detailing their nature and impact in a wide range of business environments. However, “strategic positioning” of the business model based on their interactions with other business entities has not received enough academic attention despite its implications for the new generation of start-ups in emerging markets who do not have any prior business models to emulate. This research conceptualizes a framework that would help strategists position their firm in the market by carefully analyzing its interactions with other business and social entities in the business eco-system.
