Analysis of means in marketing research

Analysis of variance, often the method of choice in evaluating the outcomes of marketing tests, can be significantly enhanced in its decision-support value. For this purpose one may apply more recently developed supplementary approaches: (1) Evaluation of main effects and interactions with Decision-Line (DL) criteria; (2) graphic multi-comparative analysis contrasted against the DL's; and (3) estimation of net component of variance for factor and interaction effects. An illustrative case history serves to highlight the more comprehensive overview and better understanding of experiment outcomes thus achieved.     

Development of models for marketing decisions

Practical, useful marketing models are a function of the skill and ingenuity applied during their development. A good deal of creative art, within a framework of systematic, scientific procedure, goes into the building of new marketing models. In practice a marketing organization may do well to gain experience with off-the-shelf models and to proceed to specific, tailor-made projects gradually as experience and skills grow. guidelines for over-all programs and specific procedures in model building are provided and illustrated with examples.

Am Puls des deutschen Wohnimmobilienmarktes

In its recent history, Germany has faced many serious economic crises. Remarkably, these crises all had a completely different impact on local housing markets. Some crises occurred at the national level, while others only took place at the regional level. Interestingly some crises were seemingly unnoticed by the German housing market. Hence, the question arises why the German housing market reacted differently to these crises and to what extent economic policy decisions were involved.     

The economics of quality in the specialty coffee industry: insights from the Cup of Excellence auction programs

This study estimates price determinants for specialty green coffee auctions using records from the 2004–2010 Cup of Excellence programs hosted by the Alliance for Coffee Excellence. While some literature on coffee has focused on certifications and sustainability labels, the discussion of price determinants has been limited. This article replicates one of the first publications on price determinants and formulates a new model to more accurately describe the market. We include the necessary additional variables and estimate the model using a truncated maximum likelihood estimation technique. While sensory quality has a strong effect on price, the highest premiums stem from obtaining a top rank compared to other coffees from the same country, and North American buyers are more responsive to sensory quality than buyers in Asian and European markets.     

Quo vadis Wohnungspolitik?

The massive increase of property prices in some regions of Germany is a direct consequence of the ongoing financial and debt crisis. Low interest rates and high inflation expectations increase the demand for real estate. In addition to a potential price bubble risk, social problems arouse more and more public interest. Currently, many tenants are facing significant rent increases. Thus, the shortage of housing dominates the current housing policy discussions. The so-called “package for affordable building and living” includes stricter rent controls and other economic policy interventions which aim to ease the situation in the real estate market, but the interventions have the opposite effect.
