The Home Bias in Equities and Distribution Costs

We show that incorporating distribution costs into a general equilibrium model of international portfolio choice helps to explain the home bias in international equity investment. Our model is able to replicate observed investment positions for a wide range of parameter values, even if agents have an incentive to hedge labor income risk by purchasing foreign equity. This is because the existence of a retail sector affects both the correlation of domestic returns with the domestic price level and the correlation between financial and non‐financial income.     

Salespersons as Internal Knowledge Brokers and New Products Selling: Discovering the Link to Genetic Makeup

Managers increasingly realize the importance of involving the sales force in new product development. However, despite recent progress, research on the specific role of the sales force in product innovation‐related activities remains scarce. In particular, the importance of a salespersons' internal knowledge brokering has been neglected. This study develops and empirically validates the concept of internal knowledge brokering behavior and its effect on selling new products and developing new business, and explores whether a salesperson's internal brokering qualities are determined by biological traits. The findings reveal that salespeople with the DRD2 A1 gene variant engage at significant lower levels of internal knowledge‐brokering behavior than salespeople without this gene variant, and as a result are less likely to engage effectively in new product selling. The DRD4 gene variant had no effect on internal knowledge brokering. Management and future research implications are discussed.     

Abschaffung der Abgeltungsteuer — gerechter und steuersystematisch einheitlicher?

There is a rising political discussion in Germany around abolishing the final withholding tax on capital income. The German tax reforms that introduced this tax lowered tax rates, in particular on interest income. According to some authors, the growing inequality of income and property is a strong argument for the higher taxation of capital income. However, other authors argue that the neutrality aspects concerning private investment are inadequate. An abolishment of the final withholding tax would not solve these problems and, moreover, would turn back the achieved improvements. Therefore, the German Council of Economic Experts suggests complementing the previous reforms by introducing an allowance for corporate equity.     

VALUATION OF BARRIER OPTIONS VIA A GENERAL SELF‐DUALITY

Classical put–call symmetry relates the price of puts and calls under a suitable dual market transform. One well‐known application is the semistatic hedging of path‐dependent barrier options with European options. This, however, in its classical form requires the price process to observe rather stringent and unrealistic symmetry properties. In this paper, we develop a general self‐duality theorem to develop valuation schemes for barrier options in stochastic volatility models with correlation.
