Is Chinese National Health Insurance Effective in the Face of Severe Illness? A Perspective from Health Service Utilization and Economic Burden

Over the past decade, health insurance coverage has expanded dramatically in China. Health insurance benefits, however, remain shallow or ambiguous. This study examines the effect of Chinese national health insurance policy on health service utilization and economic burden in urban settings using the Urban Resident Basic Medical Insurance Household Survey. We employ the Heckman selection model to correct for selection bias among hospital inpatients, and find that compared to individuals without health insurance, those with health insurance are more likely to be admitted to the hospital when their physicians recommended them to enter the hospital as inpatients. Health insurance is also associated with about 45.6 % decrease in out-of-pocket inpatient expenditures. Individuals with urban employee basic medical insurance see the largest decrease in economic burden, followed by individuals with urban resident basic medical Insurance, and those with new rural cooperative medical insurance.     

Kapitalmarktorientierte Unternehmensbewertung bei asymmetrischer Besteuerung von Soll- und Habenzinsen

Drukarczyk and Lobe argue that the value of a company depends on individual preferences for leveraged or unleveraged companies if debt and credit interest rates after personal taxes differ. Consequentially they derive two preference-dependent valuation formulas. Based on these results an increasing amount of literature proposing preference-dependent valuation formulas emerged. We claim that this has to be viewed critically. In order to show that even in a world of different debt and credit interest rates after personal taxes a market value can be determined we develop a new version of the Tax CAPM. Based on this model the market value of leveraged and unleveraged companies is derived. Finally we show that the corresponding valuation function significantly differs from the preference-dependent valuation formulas.     

Corporate valuation using imprecise cost of capital

If the estimated cost of capital bears a standard error, the estimation remains imprecise and firm values are biased on average, even though the estimator of the cost of capital is unbiased. Literature contributes approaches using adjusted discount factors to correct for such biases. This paper examines the theoretical and practical problems arising from the use of these approaches which are most likely to occur in the context of terminal value estimation. The adjusted discount factors imply time-dependent discount rates. Therefore, the commonly used valuation formula for perpetuities (Gordon formula) is no longer suitable to estimate unbiased terminal values. To continue application of this formula, this paper derives a new formula to directly adjust the cost of capital for estimation errors which yields unbiased terminal values.     

Unternehmensbewertung bei wertabhängiger und autonomer Finanzierungspolitik unter Berücksichtigung einer Kursgewinnbesteuerung

The German tax reform in 2009 entails the general taxation of realized capital gains. The objective of this paper is to investigate the effect of a differentiated taxation of dividend payments and capital gains on discounted cash flow valuations. We develop explicit und practical useful valuation formulas for the free cash flow approach in case of financing based on market values and the adjusted present value approach in case of autonomous financing. Furthermore it is shown how the required risk-adjusted cost of equity can be derived from a modified Tax-CAPM. Finally we discuss how the particularities resulting from the new German tax law can be taken into account in discounted cash flow valuations.     

Residual income valuation and management remuneration under uncertainty: a note

The so-called Residual Income Valuation theorem states that the value of a project or a firm can be determined either on the basis of cash flows between the firm and its owners or by using residual incomes, provided that cash flows and residual incomes are derived from a set of accounting data that fulfills certain regularity conditions. Residual income is defined as accounting earnings reduced by a capital charge on book equity capital. In this paper it is shown that this theorem also applies when residual incomes and in particular the discount factors are uncertain. Risk-aversion of principals and agents is taken into account on the basis of properly defined risk-adjusted discount rates. This approach is preferred as it facilitates practical application. Implications are drawn with regards to valuation but also to the design of management remuneration systems. It is shown that the capital charge rate used to determine the performance-related compensation component should be reduced below the risk-adjusted rate, if the fixed component falls below a certain threshold. Absent agency cost or other externalities, the reduction of the capital charge rate is required to avoid underinvestment.
