Social Value Orientation and Climate Strength as Moderators of the Impact of Work Group Cooperative Climate on Affective Commitment

We investigate the moderating role of an individual's social value orientation (which refers to self‐ versus other‐regarding preferences) and of climate strength (which refers to the extent of agreement among group members on group norms and values) on the relationship between work group cooperative climate and affective commitment among professional employees. We develop two plausible but opposite hypotheses on the moderation effect of social value orientation, one based on the behavioural assimilation assumption and the other on goal transformation theory. We argue that the work group's climate strength is an important contingency factor that affects which of both contradictory predictions holds. In a sample of 209 academic employees of a Belgian university, we find support for our arguments. Specifically, a cooperative climate enhances the affective commitment of employees with a prosocial value orientation (as predicted by the behavioural assimilation argument) but only when there is strong consensus among group members about the group's climate (high climate strength). Conversely, for those whose social value orientation is towards the self rather than others, a cooperative climate enhances affective commitment (consistent with goal transformation theory), especially when the climate is not agreed upon (low climate strength). These findings underscore recent claims that the predictive power of different theories in organizational behaviour depends on an individual's motives and values. We discuss the implications of our findings for the management of work groups consisting of employees with different social value orientations.     

Predicting loss given default (LGD) for residential mortgage loans: A two-stage model and empirical evidence for UK bank data

With the implementation of the Basel II regulatory framework, it became increasingly important for financial institutions to develop accurate loss models. This work investigates the loss given default (LGD) of mortgage loans using a large set of recovery data of residential mortgage defaults from a major UK bank. A Probability of Repossession Model and a Haircut Model are developed and then combined to give an expected loss percentage. We find that the Probability of Repossession Model should consist of more than just the commonly used loan-to-value ratio, and that the estimation of LGD benefits from the Haircut Model, which predicts the discount which the sale price of a repossessed property may undergo. This two-stage LGD model is shown to perform better than a single-stage LGD model (which models LGD directly from loan and collateral characteristics), as it achieves a better R² value and matches the distribution of the observed LGD more accurately.     

A cross-country analysis of the Okun's Law coefficient convergence in Europe

The paper examines whether or not evidence is consistent with convergence of the Okun's Law coefficient (OLC) among several alternative groupings of European economies. A two-step empirical strategy is employed. The first step obtains rolling regression estimates of the OLC for individual European countries. The second step examines how the cross-country variance of the OLC evolves over the decade until 2002 in the selected country groupings. Evidence is found consistent with convergence of the OLC among northern European countries, and among countries with centralized wage bargaining, but an absence of convergence in other country groups.     

Definition and psychometric validation of a measurement index common to website and store images

To mesh together their channels and better handle their multichannel management, retailers must better evaluate and coordinate their various channels. They need more precise and more complete measurement instruments to compare the channels in terms of characteristics perceived by their customers. Using the procedure specific to formative variables, this research results in a particularly comprehensive measurement index that culls 10 channel image dimensions (offering, price, layout, accessibility, promotions, customer service, advice, reputation, institution, connections with other channels) from the 40 strictly identical items for the website and the stores. Various qualitative and quantitative surveys examine across several samples of customers of a major French multichannel retailer, including one sample of 1,478 respondents. This study delineates the scope of website and store images and defines reliable scales for evaluating each image dimension of the channels, including those totally missing from the literature. This measurement tool harnesses website and store characteristics that are very operational and easily actionable. This study demonstrates that a website can be described and analyzed along the same lines as a store, and shows the relevance of incorporating connections with other channels, particularly into the scope of website image.     

Fragmented property rights and royalty bargaining

We consider production by a firm that relies on the patent rights that are held by other actors. Before production can take place, bargains have to be struck with each patent holder over the royalty per unit produced. In the negotiations, a patent holder must be mindful of the fact that a large royalty will increase the product price and lower demand for the final product. Hence each patent holder would prefer to gain a large royalty at the expense of rivals. When the producer makes the first offer in an alternating offer framework, we analyze whether it should conduct negotiations sequentially with some grouping of patent holders or simultaneously. We demonstrate that the producer will prefer simultaneous negotiation. An individual patent holder would prefer to negotiate early with the producer, and then to see remaining rights holders negotiate simultaneously. A firm that holds several patents would want to negotiate royalties on each one sequentially and then have simultaneous negotiation of payments to other rights holders.     

The welfare state after the great recession

The economic crisis has given rise to significant challenges to the welfare state. Given that welfare expenses account for a large proportion of all state spending in the member countries of the European Union, reducing government spending means cutting welfare measures. Yet social protection, in particular unemployment insurance benefits and minimum income support, has significantly softened the impact of the crisis for millions of individuals. The global recession calls into question the financial viability of current programmes, and the crisis is being used by some as an opportunity to roll back the welfare state permanently. The present Forum discusses challenges to and opportunities for the welfare state after the crisis.     

Say's involvement in the 1819 French edition of Ricardo's Principles and the issue of rent

This paper focuses on Say's contribution to the first French edition of Ricardo's Principles and on the analytical consequences of his involvement on the issue of rent. Part one investigates the “story” of this edition. It stresses Say's friendship with the translator, his involvement in this publication and his attitude toward Ricardo. Part two analyses how elements from Say's thought were introduced into Ricardo's theory of rent through this edition. These elements conveyed ideas which were definitely at odds with Ricardo's theory and misrepresented Ricardo's true concept of differential rent which was central to his theory.     

Potential output growth in several industrialised countries a comparison

In this paper, we present international comparisons of potential output growth among several economies—Canada, the euro area, France, Germany, Italy, Japan, the Netherlands, the United Kingdom, and the United States—for the period 1991–2004, for which we construct consistent and homogenous capital stock series. The main estimates rely on a structural approach where output of the whole economy is described by a Cobb–Douglas function and Total Factor Productivity (TFP) is estimated allowing for possible breaks in the deterministic trend. The results confirm that over the considered period the potential gross domestic product growth has been faster in the United States than in other studied countries, reflecting a combination of higher labour contribution and faster TFP growth. Overall, this paper might help to shed some light on cross-country differences in economic performance over the recent period.     

The level and quality of Value-at-Risk disclosure by commercial banks

In this paper we study both the level of Value-at-Risk (VaR) disclosure and the accuracy of the disclosed VaR figures for a sample of US and international commercial banks. To measure the level of VaR disclosures, we develop a VaR Disclosure Index that captures many different facets of market risk disclosure. Using panel data over the period 1996–2005, we find an overall upward trend in the quantity of information released to the public. We also find that Historical Simulation is by far the most popular VaR method. We assess the accuracy of VaR figures by studying the number of VaR exceedances and whether actual daily VaRs contain information about the volatility of subsequent trading revenues. Unlike the level of VaR disclosure, the quality of VaR disclosure shows no sign of improvement over time. We find that VaR computed using Historical Simulation contains very little information about future volatility.     

Short Selling and the Weekend Effect in Nasdaq Stock Returns

We examine daily short selling of Nasdaq stocks to explore whether speculative short selling causes a significant portion of the weekend effect in returns. We identify a weekend effect in speculative short selling whereby it constitutes a larger percentage of trading volume on Mondays versus Fridays. We find an opposite effect in dealer short selling, consistent with market makers adding liquidity and stability. Our main finding is that speculative short selling does not explain an economically meaningful portion of the weekend effect in returns, even among the firms most that are most actively shorted. This finding contradicts some prior studies.
