How Issue Size, Risk, and Complexity are Influencing External Financing Costs: German IPOs Analyzed from an Economies of Scale Perspective

This paper is focused on the cost of raising capital in Germany. A cross-sectional analysis of flotation cost data for 117 IPOs over the years 1993–1998 is presented. We find average flotation costs to be 7.77 percent of gross proceeds, while underwriting fees average 5.01 percent. Our results extend the literature in two important directions. First, contrary to the conventional economies of scale view we find marginal spreads to be rather constant in gross proceeds and to be higher for more risky and more complex offerings. Fixed costs amount to 5 to 9 percent of underwriting fees. Second, by applying a principal component analysis we find issue size, an issuer risk factor, and an offering method complexity factor to have an economicaly meaningful impact on underwriting fees.     

Wage versus efficient bargaining in oligopoly

This paper combines internal bargaining between firms and their employees with a situation of imperfect competition, in particular a Cournot‐oligopoly. Wage bargaining is compared with simultaneous negotiations on wages and employment (efficient bargaining). It turns out that for a large range of parameter values a prisoner's dilemma concerning profits exists. The dominant strategy is efficient bargaining, while the joint profits are maximized with wage negotiations. A simplified example considers economic welfare and utility of the unions. Different welfare measures are considered like the usual IO measure of consumer and producer surplus as well as others. The term ‘efficient bargaining’ is not justified (at least for the present example) if the profits and the rents of the unions are considered, as these are maximized with wage bargaining. However, consumer and producer surplus are highest with efficient bargaining. Copyright © 2006 John Wiley & Sons, Ltd.     

Der neue Standard zur bilanziellen Abbildung von Versicherungsverträgen (IFRS 17) – Eine kritische Analyse der Auswirkungen auf die Versicherungsbranche

The new standard for the accounting of insurance contracts (IFRS 17) will entail substantial changes for the insurance industry. In the following article the new standard is critically analyzed. First and foremost the coming valuation model, the so-called building block approach, is presented which will be the basis for all insurance contracts within the scope of IFRS 17. (For certain insurance contracts, especially those with direct participation features, or for less complex or short-term insurance contracts, there are some modifications.) To be more precise, IFRS 17 introduces an enterprise-specific valuation approach that is grounded on the so-called fulfilment value. This fulfilment value is determined by four separate building blocks (fulfilment-cashflow, discount rate, risk margin and contractual service margin), which will be addressed in detail. Finally, major changes in performed accounting practices that insurance enterprises are confronted with and will have to adapt to in their financial statements and accounts are pointed out.     

Do Spillovers Stimulate Incremental or Drastic Product Innovations? Evidence from German Establishment Data*

Despite the generally recognized importance of knowledge spillovers, the empirical literature is essentially silent on the type of innovation stimulated by spillovers. We estimate the determinants of product innovations differing in their degree of newness to the adopting firm. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of participation in R&D cooperation. Spillovers exert no such independent influence on drastic innovation activities. The results support the hypothesis that establishments face difficulties in using knowledge that comes from areas they are not familiar with. Establishments exploit spillovers for incremental innovations rather than for drastic innovations. To some degree R&D cooperation can help to overcome the difficulties in using spillovers for drastic innovations. Furthermore, our estimates provide evidence that the firm's own R&D effort and the use of outside information are substitutes.     

Analyse der Abwicklung von gesetzlichen Krankenkassen per sozialrechtlicher Schließung oder per Insolvenzverfahren

Private as well as statutory health insurers have various ways of insolvency. Although the Insolvency Act has been applied for statutory health insurance since 2010, these new options were not used up to now. Anyway, the legislators laid the preference out of closure. This article investigates how the priority of closure could be in contradiction to the applicability of the Insolvency Act. It is asked, whether the introduction of the insolvency capability of health insurance funds was rather to assimilate the frame conditions relating to pension promises than creating a real alternative. One reason could be, that the Insolvency Act is not only generally applicable in the liquidation of a health insurance fund, but potentially even the best alternative. The insolvency proceedings for example are advantageous for health insurance funds within the same group because the maximum load is split and lower than it would be by a closure by social law and in addition to that the PSV is obligatory. The results show, that the generally-accepted, not limited standard preference of closure as laid out by the legislators in § 171b (3) S. 2 SGB V, seems inexplicable. The paper draws parallels to private health insurance companies under Solvency II and opens up new perspectives for legislative measures.     

Optimal portfolios and Heston's stochastic volatility model: an explicit solution for power utility

Given an investor maximizing utility from terminal wealth with respect to a power utility function, we present a verification result for portfolio problems with stochastic volatility. Applying this result, we solve the portfolio problem for Heston's stochastic volatility model. We find that only under a specific condition on the model parameters does the problem possess a unique solution leading to a partial equilibrium. Finally, it is demonstrated that the results critically hinge upon the specification of the market price of risk. We conclude that, in applications, one has to be very careful when exogenously specifying the form of the market price of risk.     

Deposit interest rates, asset risk and bank failure in Croatia

Financial deregulation, while beneficial in the long-term, seems to be linked to instability. Intense competition for deposits appears to be an ingredient in instability. We examine the aftermath of deregulation in Croatia, which included rapid growth of both deposits and deposit interest rates, followed by numerous bank failures.

Using panel regression techniques, we find evidence of “market-stealing” via high deposit interest rates. We connect high deposit interest rates to bank failure using logit models. High deposit interest rates were a reliable signal of risk-taking. When supervisory capabilities and powers are weak, deposit interest rate regulation may be worth considering.     

Participation and division of labour: a West German case study

Motivation and productivity were increased when the traditional division of labour and surplus was modified to give workers extended tasks and profit-shares in firm Z. In X, traditional division of labour combined with worker-shareholding and formal, representative participation failed to improve motivation.     

Bankruptcy, Counterparty Risk, and Contagion

This paper provides a unifying framework for the modeling ofvarious types of credit risks such as contagion effects. Weargue that Markov chains can efficiently be used to tackle theseproblems. However, our approach is not limited to pricing problemswith contagion. On the theoretical side, we derive pricing formulasfor three building blocks that are generalizations of contingentclaims studied in Lando (1998). These claims can be thoughtof as atoms forming the basis for all credit risk payments.Furthermore, we demonstrate that, in general, all contingentclaims exposed to credit risk satisfy a system of partial differentialequations. This is the key result to calculate prices of creditrisk claims explicitly and efficiently.     

Asset allocation over the life cycle: How much do taxes matter?

We study the welfare effect of tax-optimizing portfolio decisions in a life cycle model with unspanned labor income and realization-based capital gain taxation. For realistic parameterizations of our model, certainty equivalent welfare gains from fully tax-optimized portfolio decisions are less than 2% of present financial wealth and lifetime income compared to a heuristic portfolio policy ignoring the taxation of profits (capital gains, interest and dividend payments). Compared to a heuristic portfolio policy that only ignores the realization-based feature of capital gain taxation and instead assumes mark-to-market taxation, these gains are less than 0.5%. That is, our work provides a justification for ignoring taxes in life cycle portfolio choice problems – a wide-spread assumption in that literature. However, if capital gains are forgiven at death (as in the U.S.), investors with strong bequest motives face substantial welfare costs when not tax-optimizing their portfolio decisions towards the end of the life cycle.
