A comparison of different pay-per-bid auction formats

Pay-per-bid auctions are a popular new type of Internet auction that is unique because a fee is charged for each bid that is placed. This paper uses a theoretical model and three large empirical data sets with 44,614 ascending and 1,460 descending pay-per-bid auctions to compare the economic effects of different pay-per-bid auction formats, such as different price increments and…

The perils of performance measurement in the German mutual-fund industry

We document a curious feature of the German mutual fund industry. Unlike U.S. mutual funds, funds domiciled in Germany do not necessarily compute their net asset values (NAV) as of market close. Using a sample of German equity funds, we infer each fund's NAV closing time from the best-fit market model using both maximum likelihood and Bayesian estimation. The results of both…

Specific investment and negotiated transfer pricing in an international transfer pricing model

We study the efficiency of negotiated transfer pricing for solving a bilateral hold-up problem in a multinational enterprise. We show that negotiated transfer pricing will generally not provide incentives for an efficient renegotiation of the initial contract and efficient investments because the divisions possess only one instrument for solving two problems. Either they minimize…

Both theoretical considerations as well as empirical findings report mixed results on the relationship between sustainability disclosure and sustainability performance. Theoretical considerations are mainly based on legitimacy theory and voluntary disclosure theory. Due to shortcomings of previous studies with regard to the measurement of the main variables, our paper concentrates on…

Why do corporate actors engage in pro-social behavior? A Bourdieusian perspective on CSR

Drawing on Pierre Bourdieu’s theory of social practice, this article develops a novel approach to the study of corporate social responsibility (CSR). According to this approach, pro-social activities are conceptualized as social practices that individual managers employ in their efforts to attain social power. Whether such practices are enacted or not depends on (1) the particular…

Aubin property and uniqueness of solutions in cone constrained optimization

We discuss conditions for the Aubin property of solutions to perturbed cone constrained programs, by using and refining results given in Klatte-Kummer "Nonsmooth Equations in Optimization", Kluwer, 2002. In particular, we show that constraint nondegeneracy and hence uniqueness of the multiplier is necessary for the Aubin property of the critical point map. Moreover, we give…

Theory matters for financial advice!

We show that the optimal asset allocation for an investor depends crucially on the theory with which the investor is modeled. For the same market data and the same client data different theories lead to different portfolios. The market data we consider is standard asset allocation data. The client data is determined by a standard risk profiling question and the theories we apply are…
