Leverage and reinsurance effects on loss reserves in the United Kingdom’s property–casualty insurance industry

We examine the relation between loss reserving errors, leverage and reinsurance in the UK’s property–casualty insurance industry. We find that financially weak insurers under-estimate reserves to reduce leverage, and so pre-empt costly regulatory scrutiny. However, at very high leverage, insurers over-reserve, suggesting a non-linear relation between leverage and reserving policy. We also investigate whether monitoring by reinsurers reduces reserving errors, and find that highly reinsured insurers are less likely to make loss reserve errors. However, the use of proportional reinsurance does not affect loss reserve accuracy.     

Evaluating underlying inflation measures for Russia

We apply several tests to the underlying inflation measures used in practice by central banks and/or proposed in the academic literature in an attempt to find the best-performing indicators. We find that although there is no single best measure of underlying inflation, indicators calculated on the basis of dynamic factor models are generally among the best performers. These best performers not only outdid the simpler traditional underlying indicators (trimmed and exclusion-based measures) but also proved to be economically meaningful and interpretable.     

Learning, communication, and the bullwhip effect

We investigate the effect of learning and communication on the bullwhip effect in supply chains. Using the beer distribution game in a controlled laboratory setting, we test four behavioral hypotheses – bounded rationality, experiential learning, systems learning, and organizational learning – by systematically manipulating training and communication protocols. We find that order variability decreases significantly in a setting in which participants start with hands-on experience, and are then allowed to formulate team strategies collaboratively. This result indicates that while training may improve individuals’ knowledge and understanding of the system, it does not improve supply chain performance unless supply chain partners are allowed to communicate and share this knowledge. Our results indicate that the bullwhip effect is, at least in part, caused by insufficient coordination between supply chain partners.     

Anger mediates the effect of ostracism on risk-taking

The present research tested the effects of being ostracized on risk-taking behavior and how emotional responses to ostracism mediate these effects. In two experiments, undergraduates were either ostracized or included during an Internet ball-toss game (Cyberball). In Experiment 1 (N = 52), ostracism increased self-reported risk-taking inclinations, and the relation between ostracism and risk-taking was mediated by feelings of anger, but not control. In Experiment 2 (N = 72), ostracism increased risky driving during a driving video game. The effect of ostracism on risk-taking was again mediated by post-ostracism anger (but not control or ostracism-induced sadness). This research suggests that anger elicited by ostracism may increase risk-taking.     

Exploring the generative power of performance measurement systems design

Prior studies recognise the enabling power of incompleteness in the design of Performance Measurement Systems (PMS). We add to these studies by exploring the ‘time dimension’ of incompleteness as a way to delve into the generative power of design. To this aim, we rely upon the experience of a knowledge-intensive organization during the design of a new PMS. While knowledge complexity engaged the participants within an open-ended design process, incomplete measures were associated with unfolding memories of the past and confident beliefs in future solutions, which generated effects through the knowledge gaps that they entailed, as well as through the projections in the past and in the future that they enabled. By delving into the time dimension of incompleteness, we add to prior studies on PMS design by showing the relationships between managers' hopes for the future, patterns of memory (and forgetting) of the past and incompleteness in design. In particular, we show that although incomplete measures stimulate managers' aspirations and search for further possibilities, it is forgetting about the past (its evolving memories) that triggers this search, facilitates new actors entering the design process and enables unpredictable outcomes of design.     

Ex post Merger Evaluation in the U.K. Retail Market for Books

This paper evaluates the price effects of the merger of two major U.K. book retailers. We use a dataset containing monthly scanner data on a sample of 200 books in 50 local markets for four years around the merger. We compare the price changes after the merger in shops located in areas where both chains were present before the merger and in areas where only one chain was present. We also investigate the country‐wide effect of the merger. We find that the merger did not result in any price increase either at the local or at the national level.     

Efficiency and Stock Performance in European Banking

Abstract:   Recent competitive pressures have progressively driven banks to strategically focus on generating returns to shareholders. Therefore, the investigation of the determinants of bank performance and their relationship with share prices has become increasingly important. This paper extends the literature on market‐based accounting to examine the relationship between stock prices and efficiency. Specifically, it investigates if changes in stock performance can be explained by changes in operating efficiency, derived by parametric and non‐parametric methods. Results seem to suggest that changes in efficiency are reflected in changes in stock prices and that stocks of cost efficient banks tend to outperform their inefficient counterparts.     

Time is money: The effect of clock speed on seller’s revenue in Dutch auctions

We study the role of timing in auctions under the premise that time is a valuable resource. When one object is for sale, Dutch and first-price sealed bid auctions are strategically equivalent in standard models, and therefore, they should yield the same revenue for the auctioneer. We study Dutch and first-price sealed bid auctions in the laboratory, with a specific emphasis on the speed of the clock in the Dutch auction. At fast clock speeds, revenue in the Dutch auction is significantly lower than it is in the sealed bid auction. When the clock is sufficiently slow, however, revenue in the Dutch auction is higher than the revenue in the sealed bid auction. We develop and test a simple model of auctions with impatient bidders that is consistent with these laboratory findings.

Aligning supply chain design for boosting resilience

Many researchers have analyzed the effect of disruptive events, such as natural disasters and economic and market forces, on global supply chains. However, there is a lack of consensus on delineating a universal collection of supply chain risk management practices that will help companies operate in a global market with large-scale disruptions. In this article, we present an analysis, in conjunction with a worldwide online survey, based on successful global brands and their supply chains. We propose a framework that deploys the dynamics of building supply chain resilience, first linking the design of the supply chain portfolio (local versus global scope, as well as strategic responsiveness versus cost reduction) with supply chain vulnerabilities (external versus internal). We describe the transition between different supply chain structures as a way of coping with disruptions and thus proactively developing resilience. In this article, we introduce both a supply chain risk management approach and the reactive-by-deployment mode, as illustrated by successful global company examples.
