Abstract

Purpose

The purpose of this paper is to investigate the accuracy and volatility of different methods for estimating and updating hedonic valuation models.

Design/methodology/approach

The authors apply six estimation methods (linear least squares, robust regression, mixed-effects regression, random forests, gradient boosting and neural networks) and two updating methods (moving and extending windows). They use a large and rich data set consisting of over 123,000 single-family houses sold in Switzerland between 2005 and 2017.

Findings

The gradient boosting method yields the greatest accuracy, while the robust method provides the least volatile predictions. There is a clear trade-off across methods depending on whether the goal is to improve accuracy or avoid volatility. The choice between moving and extending windows has only a modest effect on the results.

Originality/value

This paper compares a range of linear and machine learning techniques in the context of moving or extending window scenarios that are used in practice but which have not been considered in prior research. The techniques include robust regression, which has not previously been used in this context. The data updating allows for analysis of the volatility in addition to the accuracy of predictions. The results should prove useful in improving hedonic models used by property tax assessors, mortgage underwriters, valuation firms and regulatory authorities.

Abstract

The first part of this chapter addresses the history and development of the International Study Association of Teachers and Teaching (ISATT) and its engagement with the global educational community. We provide an account of the context and background against which ISATT developed as well as information about the founders’ orientations and the actions that led to ISATT’s birth. The second part of the chapter uses patterns of topic focus as graphic indicators of the evolution of ISATT’s research interests expressed through publication titles.

Abstract

This article argues in favor of using motion picture screens as a medium for the presentation of advertising messages. The concept and history of cinema screen advertising is examined, previous and contemporary audience research on cinema ads is presented, and an argument favoring the adoption of cinema screen advertising is offered. Virtually all of the American mass media are characterized as commercial in the sense of being largely advertising supported. The most commonplace and pervasive media‐newspapers, television, radio, and magazines—all share this characteristic. Cinema, however, is and has been supported almost entirely by patrons. Moreover, today there is much discussion as well as research on how new communications technologies might be employed to meet advertising and marketing needs. This article examines a mass communications technology which has been present for a century but has been virtually untapped as an advertising and marketing medium for reaching American consumers. Few individuals think of theatrically exhibited motion pictures as a likely medium to be supported by advertising. Introductory mass communications, advertising, and marketing texts regularly omit mention of this notion. This article argues that in an age of new communications technologies, use of this older technology for advertising and marketing carries many of the same advantages as does use of the emerging ones. This article explores the concept of cinema advertising, presents previous and contemporary audience research on cinema ads, and argues that today, especially, this long‐neglected medium should be adopted for the dissemination of information by the consumer marketing and advertising industries.

Abstract

Because management is the “art of the possible,” managers need to understand themselves and workers who are charged with carrying out plans. Seemingly, there is a lot of assistance available; indeed, the make‐up of the successful manager is the focus today of a vast educational, consulting and publishing establishment.

Abstract

TITAN is an information management environment designed for fast retrieval of records from extremely large (several million records) collections of data. It provides unlimited multi‐key retrieval and, unlike most retrieval systems, the more terms specified in the query the faster the query is performed. This paper describes the facilities provided by TITAN, explains the underlying theory of signature files behind it and analyses its strengths and weaknesses relative to other tools on the market.

Abstract

Purpose

The goal of this study is to examine the association between managers' sexually-oriented behavior in publicly traded firms and subsequent stock market reactions. Both sexual harassment and nonharassing sexually-oriented behavior (i.e. workplace romance) are associated with negative shareholder reactions. The authors also examine factors that may alter the stock market reaction and those that may reduce the risk of lawsuit in sexual harassment cases.

Design/methodology/approach

Information about incidents of sexually-oriented behavior was collected from media reports and content coded. An event study with a stock market reaction was used to measure the impact of disclosed sexually-oriented behaviors. Logistic regression was used to assess the relationship between incident characteristics and sexual harassment lawsuits.

Findings

Disclosure of managers' sexually-oriented behavior is associated with a negative stock market reaction. Interestingly, the reaction was not more severe for sexual harassment disclosures compared to nonharassing behavior (i.e. workplace romance). Results also suggest that terminating a manager prior to disclosure of an event is negatively related to a harassment lawsuit.

Originality/value

The authors report this as the first study to focus on the stock market reaction of sexually-oriented harassing and nonharassing behavior of managers. This work complements research that documents the negative impact of sexual harassment on individuals by demonstrating these behaviors are associated with loss and risk at an organizational level.
