Real estate and real estate finance as a research field—an international overview

We present a citation-based analysis of the most important journals on real estate and real estate finance over a time period from 1986 to 2010. For each year, those three articles with the highest number of citations according to Google Scholar are identified. A thorough analysis of all 75 selected articles reveals that the focus of interest has been on (1)empirical research, (2) mainly using data ofresidential real estate, with (3) the primary objective of evaluating real estateinvestment until the midst 1990s. In order to derive reliable risk-return relations for real estate investment, (4) asset pricing as the main task of real estateappraisal is in the centre of attention, too. Appraisal issues have relatively gained importance for the last fifteen years in comparison to investment issues. Interdisciplinary aspects and sustainable issues are only very rarely integrated in appraisal methods, the focus is primarily on maximizing economic returns. Therefore, our citation analysis confirms that the Financial Management Approach of Dasso and Woodward (1980) is the predominant approach particularly in the United States. Our findings regarding our basic sample of articles are cross-checked by several robustness tests. For future research activities, it seems to be quite promising to focus on the one hand on interdisciplinary aspects and on the other hand to contribute to the theoretical foundation of real estate with the aim of developing a common body of knowledge.     

Joint decisions on household membership and human capital accumulation of youths. The role of expected earnings and local markets

This paper analyses the effects of expected earnings and local markets conditions on the behaviour of young adults with high school diplomas. Decisions to either remain in the parental home or form a new household are modelled jointly with those of either gaining work experience or investing in a university education. Expected lifetime earnings are found to play a crucial role in determining the choice of studying and residing with parents. Poor labour market opportunities discourage young people from working and induce them to study. The cost of housing greatly influences the choice of working and leaving the parental home.

Point‐of‐Use Hybrid Inventory Policy for Hospitals

Modern point‐of‐use technology at hospitals has enabled new replenishment policies for medical supplies. One of these new policies, which we call the hybrid policy, is currently in use at a large U.S. Midwest hospital. The hybrid policy combines a low‐cost periodic replenishment epoch with a high‐cost continuous replenishment option to avoid costly stockouts. We study this new hybrid policy under deterministic and stochastic demand. We develop a parameter search engine using simulation to optimize the long‐run average cost per unit time and, via a computational study, we provide insights on the benefits (reduction in cost, inventory, and number of replenishments) that hospitals may obtain by using the hybrid policy instead of the commonly used periodic policies. We also use the optimal hybrid policy parameters from the deterministic analysis to propose approximate expressions for the stochastic hybrid policy parameters that can be easily used by hospital management.      

Life-Coaching als Bestandteil von Führungskräfte-Coaching

Executive coaching represents a significant tool of human resources development and is applied to strengthen leadership and management skills. Regardless of specific professional issues on and around the job itself, experience reveals that personal issues should also represent an integral constituent of executive coaching. Indeed, managers do not only encounter professional challenges, but are challenged in their whole personality. Hence, executive coaching expands to life coaching. Based on a specific case study regarding work life balance the following article illustrates how life coaching may successfully be applied in a systematic manner and how the aspects function and human being are mutually dependent.     

Retailer Transshipment versus Central Depot Allocation for Supply Network Design

We consider a supply chain structure with shipments from an external warehouse directly to retailers and compare two enhancement options: costly transshipment among retailers after demand has been realized vs. cost‐free allocation to the retailers from the development of a centralized depot. Stochastic programming models are developed for both the transshipment and allocation structures. We study the impact of cost parameters and demand coefficient of variation on both system structures. Our results show an increasing convex relationship between average costs and demand coefficient of variation, and furthermore that this increase is more pronounced for the allocation structure. We employ simulation and nonlinear search techniques to computationally compare the cost performance of allocation and transshipment structures under a wide range of system parameters such as demand uncertainty and correlation; lead times from the external warehouse to retailers, from warehouse to central depot, and from depot to retailers; and transshipment, holding, and penalty costs. The transshipment approach is found to outperform allocation for a broad range of parameter inputs including many situations for which transshipment is not an economically sound decision for a single period. The insights provided enable the manager to choose whether to invest in reducing lead times or demand uncertainty and assist in the selection of investments across identical and nonidentical retailers.     

Estimating and comparing adverse event probabilities in the presence of varying follow-up times and competing events

Safety analyses of adverse events (AEs) are important in assessing benefit–risk of therapies but are often rather simplistic compared to efficacy analyses. AE probabilities are typically estimated by incidence proportions, sometimes incidence densities or Kaplan–Meier estimation are proposed. These analyses either do not account for censoring, rely on a too restrictive parametric model, or ignore competing events. With the non-parametric Aalen-Johansen estimator as the “gold standard”, that is, reference estimator, potential sources of bias are investigated in an example from oncology and in simulations, for both one-sample and two-sample scenarios. The Aalen-Johansen estimator serves as a reference, because it is the proper non-parametric generalization of the Kaplan–Meier estimator to multiple outcomes. Because of potential large variances at the end of follow-up, comparisons also consider further quantiles of the observed times. To date, consequences for safety comparisons have hardly been investigated, the impact of using different estimators for group comparisons being unclear. For example, the ratio of two both underestimating or overestimating estimators may not be comparable to the ratio of the reference, and our investigation also considers the ratio of AE probabilities. We find that ignoring competing events is more of a problem than falsely assuming constant hazards by the use of the incidence density and that the choice of the AE probability estimator is crucial for group comparisons.     

DOING IT WHEN OTHERS DO: A STRATEGIC MODEL OF PROCRASTINATION

This paper develops a strategic model of procrastination in which present‐biased agents prefer to perform an onerous task with someone else. This turns their decision of when to perform the task into a procrastination game—a dynamic coordination game between present‐biased players. The model characterizes the conditions under which interaction mitigates or exacerbates procrastination. A procrastinator matched with a worse procrastinator may perform her task earlier than she otherwise would: she wants to avoid the increased temptation that her peer's company would generate. Procrastinators can thus use bad company as a commitment device to mitigate their self‐control problem. (JEL C72, C73, D03, D91)     

School Readiness of Children of Immigrants: Does Parental Involvement Play a Role?*

Objectives. Using data from the Early Childhood Longitudinal Survey—Kindergarten Cohort, this article analyzes the link between parental involvement and the school readiness of children of immigrants. Methods. Multivariate regression models estimate the association between parental involvement and the school readiness in English proficiency and math scores of children of immigrants. They also estimate the impact of this association on the gap in math scores between children of immigrants and children of natives. Results. Results demonstrate that parental involvement is associated with an increase in the level of English proficiency for children of immigrants. Parental involvement also is associated with a decrease in the gap in math scores between immigrant children from English‐ and non‐English‐speaking backgrounds. Parental involvement decreases the gap in math scores between children of immigrants and children of the native born by a third of a standard deviation. Conclusion. Given that parental involvement appears to benefit children of immigrants and given that they have lower academic achievement than children of the native born, these findings suggest that parental involvement policies and practices targeting children of immigrants could help decrease the academic achievement gap between children of immigrants and children of the native born.     

Die Einführung von Mitarbeiter/innengesprächen an österreichischen Universitäten

The introduction of staff appraisal interviews in Austrian Universities This paper addresses the issue of the obligatory introduction of staff appraisal interviews in the Austrian higher education system after the implementation the law ?UG 2002“ (University Law 2002). It focuses on the cultural change process from the old university management system to a nowadays prevalent ?management by objectives“. After the introduction of the ?UG 2002“ Austrian Universities are forced to be more competitive with one another, hence an academic market is opened. Ultimately this leads to a cultural break. This is the reason why we discuss the possibilities and limitations of the implementation of appraisal interviews and target agreements from different angles. The diverse perspectives will be a theory of communication, a theory of organizations and a psychodynamic standpoint.     

Improving operational plant performance in international manufacturing networks: the effects of integrative capabilities and plant roles

Abstract

This study adopts the resource-based view to examine how two integrative capabilities of a plant embedded in a manufacturing network enhance operational performance: the capability to connect with other plants in its manufacturing network (a networking capability, NC), and the capability to integrate manufacturing processes with new product development processes (a new product development capability, NPDC). Our model tests the indirect effect of NC on cost, quality, flexibility and delivery through NPDC. Furthermore, we test if the relationship between NC and NPDC depends on the strategic role of the plant. Using survey data from a sample of 521 plants, we confirmed the mediating effect of NPDC. However, the moderation effect was not confirmed. Our findings reveal that plants can deploy NPDC capabilities, fostered by NC, independently from their role in the network. This study contributes to the understanding of plant capabilities and plant roles in manufacturing networks.
