Wrapped input selection using multilayer perceptrons for repeat‐purchase modeling in direct marketing

In this paper, we try to validate existing theory on and develop additional insight into repeat‐purchase behavior in a direct marketing setting by means of an illuminating case study. The case involves the detection and qualification of the most relevant RFM (Recency, Frequency and Monetary) variables, using a neural network wrapper as our input pruning method. Results indicate that elimination of redundant and/or irrelevant inputs by means of the discussed input selection method allows us to significantly reduce model complexity without degrading the predictive generalization ability. It is precisely this issue that will enable us to infer some interesting marketing conclusions concerning the relative importance of the RFM predictor categories and their operationalizations. The empirical findings highlight the importance of a combined use of RFM variables in predicting repeat‐purchase behavior. However, the study also reveals the dominant role of the frequency category. Results indicate that a model including only frequency variables still yields satisfactory classification accuracy compared to the optimally reduced model.

Bank risk taking and changes in the financial condition of banks' small and midsized commercial customers, 1978–1988 and 1988–1991

This study examines the pattern of bank risk taking through the 1980s and early 1990s, as reflected in the reported financial condition of banks' small and midsized customer firms. Using industry data published in Robert Morris Associates'Annual Statement Studies, we examine the ten-year period 1978–1988 to ascertain changes in the financial condition of banks' commerical customers during the 1980s, and the following three-year period 1988–1991, to determine financial condition changes in customer firms during the early 1990s. Empirical results suggest banks' small and midsized commercial clientele shifted toward riskier organizations From 1988 to 1988, confirming the popularized notion of banks' increased tolerance for risk during the 1980s. From 1988 to 1991, however, banks' client firms evidenced a pattern of risk reduction, which is consistent with the argument that banks have retrenched in their risk taking in recent years, shifting back toward a more financially sound customer base.     

A THEORETICAL ANALYSIS OF DESIGN ISSUES IN MEDICAL SAVINGS ACCOUNTS: THE POLICY IMPLICATIONS

Abstract: Numerous methods for helping consumers deal with medical care costs have been suggested. One way that has been discussed is the use of Medical Saving Accounts. A pilot program introducing Medical Spending Accounts was passed by Congress as part of the Health Insurance Reform Act of 1996. The authors review the major points of this program and attempt to examine what impact this program could have on medical care cost.     

Wird der vom Regierungsentwurf eines VVG geplante Direktanspruch des Geschädigten gegen den Pflichthaftpflichtversicherer ein stumpfes Schwert? Zur Notwendigkeit eines Informationsanspruchs des Geschädigten in der neuen Pflichthaftpflichtversicherung

The amendment of the German Act on Insurance Contracts comprises a number of substantial modifications regarding liability insurance. The most important modification is the introduction of a direct claim against the insurer with regard to all compulsory insurances. Such a direct claim is up to now only known from the motor vehicle liability insurance. Yet, a direct claim will be advantageous for the aggrieved claimant only if he manages to identify the proper insurer. As a result of the structural differences to the motor vehicle liability insurance the act of identifying the insurer is almost utterly impossible for the claimant without any help by the insured. Thus the claimant must also be given a claim against the insured to be furnished with all necessary information regarding the insurer. This right originates from sec. 242 of the German Civil Code.     

Evolution of Corporate Law and the Transplant Effect: Lessons from Six Countries

The pattern of legal change in countries that have their legalsystems transplanted from abroad differs markedly from countriesthat develop their own systems, irrespective of the legal familyfrom which their laws come. In "transplant" countries, law oftenstagnates for long periods of time; when change takes place,it tends to be radical, if not erratic. External models remaindominant even years after the law was transplanted. Althoughthere is some evidence that transplant countries have engagedin comprehensive legal reforms in response to the pressuresof globalization, it is still too early to judge whether thesenew changes can be taken as a sign that the legal systems inthese countries have started a process of endogenous legal evolution.      

Benchmarking in the Dutch Waste-Water Treatment Sector

The Dutch water boards have recently completed a performance measurement and evaluation project for waste-water treatment. This project was intended to strengthen the boards' accountability to their stakeholders and to identify starting points for performance improvement. The Balanced Scorecard was used as a framework to develop a broad set of performance indicators. This article describes the benchmarking project and how the Dutch water boards intend to use the results to improve performance. Finally, the Dutch project is compared with the UK's Best Value project.     

Does the recent success of some OECD countries in lowering their unemployment rates lie in the clever design of their labor market reforms?

In recent years some OECD countries were successful in loweringthe unemployment rate substantially while other countries werenot. In this paper we investigate to what extent successfulcountries implemented a comprehensive set of institutional reforms.We present a theoretical framework to investigate the relationshipbetween unemployment and labor market institutions (LMI) suchas labor taxes, unemployment benefits, employment protection,union bargaining power and (de)centralization of bargaining.In our empirical analysis of data over the period 1960–99of 17 OECD countries we show that particular combinations ofLMI are responsible for low unemployment rates.
