Modeling Methods for Discrete Choice Analysis

This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.     

Exploring the efficacy of healthcare quality practices, employee commitment, and employee control

This exploratory study examines healthcare quality program practices, employee commitment and control initiatives, and perceived results by surveying the directors of hospital quality programs. U.S. hospitals are renowned to be among the highest in quality, but recent studies assert that the majority of error-related deaths per year are preventable. In response, healthcare organizations have adopted quality management programs. Employee commitment and control theories propose that employee initiatives are critical to patient safety. However, little research has focused on the efficacy of employee commitment and control initiatives for quality programs at healthcare organizations. This study examines the responses from Quality and Risk Directors of 372 U.S. hospitals. The results of structural equation modeling (SEM) demonstrate that perceived quantitative and qualitative quality program results are more highly related to employee commitment and control initiatives than they are related to quality practices.     

Hybrid Choice Models: Progress and Challenges

We discuss the development of predictive choice models that go beyond the random utility model in its narrowest formulation. Such approaches incorporate several elements of cognitive process that have been identified as important to the choice process, including strong dependence on history and context, perception formation, and latent constraints. A flexible and practical hybrid choice model is presented that integrates many types of discrete choice modeling methods, draws on different types of data, and allows for flexible disturbances and explicit modeling of latent psychological explanatory variables, heterogeneity, and latent segmentation. Both progress and challenges related to the development of the hybrid choice model are presented.     

Information Quality of Interim Financial Statements

Expressing concern about the Canadian capital market environment, Boritz (2006) suggested that the accounting and auditing profession may be paying limited attention to quarterly reports. This study investigates whether fourth‐quarter adjustments are significantly different from the previous three, thereby limiting the reliability or faithful representation of the firms' results for each quarter. This study includes four years (2003–2006) of quarterly financial information of 353 Canadian public companies. Our results indicate that the volatility of net income in each of the first three quarters is considerably lower than in the final quarter. While lower volatility can improve predictability, the resulting relevance may be limited. The low volatility of reported earnings in the first three quarters suggests that either earnings management is taking place or that management may not be exercising sufficient care at the end of each of the first three quarters on the measurements that generally accepted accounting principles call for and readers of financial statements expect. This could result in quarterly financial statements that do not faithfully represent the underlying resources and obligations of the reporting firms at the end of the quarter, or the firm's performance during the quarter. Our findings support Boritz's proposition for increased audit requirements for interim reports and changes in the approach to the annual audit to integrate it more closely with interim financial reporting.
