This study examines the effects of managerial ability on information asymmetry. We use analyst forecast errors as a proxy for information asymmetry, because analysts are referred to as efficient users using firm-level data. The sample consists of 2,246 non-banking firm-years listed in Korea Stock Exchange(KOSPI) during the period 2000 to 2013. We measure managerial ability using DEA(Data Envelopment Analysis) following Demerjian et al.(2012). Using those measures, we examines the effects of managerial ability on analysts' earnings forecast errors and analysts' earnings forecast bias. The results of this study are as follows. First, we find that managerial ability are positively associated with analysts' earnings forecast accuracy. Second, we show that the firms with higher managerial ability tend to have lower the optimistic errors in analysts' earnings forecasts. This study could be useful for outside stakeholders to understand the importance of managerial ability.

Isolated left-sided portal hypertension is a rare clinical syndrome caused by splenic veno-occlusive disease. Splenic vein thrombosis and extrinsic compression causes proximal splenic vein hypertension, and the splenic blood flows into the superior mesenteric or portal vein through the upper stomach's collateral vessels, such as the short gastric, coronary, and gastroepiploic veins. Open splenectomy is recommended to treat gastrointestinal bleeding caused by isolated left-sided portal hypertension. Interventional management could be a clinically useful option for selected patients who want to avoid surgical corrections.

This study supplements the limitation as much as possible that existing literatures have, and, on the target of new registered businesses to KOSDAQ, this study presents answers to the worries raised earlier by recovering problems on causal relationship direction between foreigner investment and dividend level and by analyzing them with dividend level as an independent variable. First, with the whole samples used, dividend income rate didn't show significant relationship with foreigners' investments. It is similar to study result of the existing literature. A panel analysis, on the target of sample businesses that paid dividends before foreigners' investments originated, showed that foreigners' investments didn't have a significant effect on dividend rate. It means that foreigner investors don't have an effect on dividend level. But, a panel analysis of samples shows that foreigner investments have a significant thesis relationship with dividend level variable, that is dividend return rate, except the businesses which paid dividend before foreigners' investments originated. It means that in case foreign investors' preference is controlled, in the businesses which pay dividends, foreign investors have a significant effect on dividend level to native KOSDAQ. Especially, this study result is very significant, for it shows that dividend return rate, insignificant in existing studies, was significant when foreigners' preferences to the businesses which pay dividends was controlled. It means that the more foreigners' shares increase, the more relative importance of dividend out of all profits increases, compared with all of the amounts at the time, and that foreign investors stick to short-term profit and induce big dividend.

Prior bankruptcy studies have established that bankrupt firm's pre-filing financial ratios are different from those of healthy firms or of randomly selected going concerns. However, they may not be sufficiently different from the financial ratios of other firms in financial distress to allow the development of a ratio-based model that predicts bankruptcy with reasonable accuracy. As the result, in the multiple discriminant model, independent variables divided firms into bankrupt firms and healthy firms are retained earnings to total asset, receivable turnover, net income to sales, financial expenses, inventory turnover, owner's equity to total asset, cash flow to current liability, and current asset to current liability. Moreover four variables Retained earnings to total asset, net income to sales, total asset turnover, owner's equity to total asset indicate that these valuables classify bankrupt firms and distress firms. On the other hand, Owner's Equity to borrowed capital, Ordinary income to Net Sales, Operating Income to Total Asset, Total Asset Turnover and Inventory Turnover are selected to predict bankruptcy possibility in the Logistic regression model.
