Understanding and Predicting Demand Through Visual Characteristics and Neural Networks

Electronic Commerce, Marketing & Finance

Every season, online fashion retailers are confronted with the questions, which products to order and in what quantity. These questions are particularly important, because replenishment is difficult due to the short selling season and fashion products are perishable. Therefore, knowledge about typical product sales patterns and precise predictions can prevent costly over- or understocking for retailers.

From a theoretical perspective, fashion products are…

Product Return Management in Online Retailing

Electronic Commerce, Marketing & Finance

Online retailers are challenged by high return rates and the associated return costs.

Care for the Elderly in Germany: Efficiency, Productivity and their Determinants

An Empirical Analysis for the Years 1999 to 2009

Schriftenreihe Gesundheitswissenschaften

By 2030 the number of persons of working age in Germany will drop by 7.5 million to 42.2 million, relative to the reference year 2008.

Asset Pricing and Default Risk

Finanzmanagement

Thus, many theoretical and empirical asset pricing papers have addressed issues around the relationship between stock markets and systematic risk. Among others the following research topics have been discussed: the predictability of stock markets, the impact of economy-wide risk factors on equity returns, the modeling of such risk…

Financial Engineering and Structuring in Leveraged Buyouts

Finanzmanagement

In a Leveraged Buyout, a Private Equity investor finances the purchase price of a company to a substantial fraction with debt in addition to the equity contribution out of his fund and from the participating management. The rationale for this financing structure is the substitution of equity, as an expensive source of capital, with comparably cheap debt in order to increase the expected returns on the individual equity investment and, thus, the returns of the whole fund.…

Multiple Testing Problems in the Context of Modern Portfolio Theory

Finanzmanagement

A multiple testing problem occurs when two or more related null hypotheses are tested simultaneously. The classical significance level, which refers to the type I error of an individual test problem, is not suitable for testing a family of hypotheses. This is due to the fact that more than one true null hypothesis may erroneously be rejected. Several approaches to error control taking account of the multiplicity problem have been proposed. The focus of the present work is…
