Sibling rivalry: implications for the family business succession process

This paper deals with sibling rivalry dynamics and their impact on the succession outcome within family enterprises. While sibling rivalry plays a critical role in the succession process, there is only limited literature that addresses this important subject. This theoretical study reveals valuable insights on this topic and contributes to the existing literature. Particular attention is placed on parental behavior and attitude during childhood, sibling characteristics and the perception of parental fairness by the successors, which we advocate are the principal factors conducive not only to the emergence of rivalry among heirs but also to influencing the effectiveness of the succession outcome.     

The Effects of Corporate Social Performance on the Cost of Corporate Debt and Credit Ratings

This study investigates the differential impact that various dimensions of corporate social performance have on the pricing of corporate debt as well as the assessment of the credit quality of specific bond issues. The empirical analysis, based on an extensive longitudinal data set, suggests that overall, good performance is rewarded and corporate social transgressions are penalized through lower and higher corporate bond yield spreads, respectively. Similar conclusions can be drawn when focusing on either the bond rating assigned to a specific debt issue or the probability of it being considered to be an asset of speculative grade.     

Hard,soft or ambidextrous? Which influence style promotes managers’ task performance and the role of political skill

Abstract

Ambidexterity at the manager level focuses on the crucial, but underexplored, role of managers’ knowledge, skills, and behaviors to address competing demands and promote organizational ambidexterity. As such, to successfully complete their assigned duties, managers need to employ the appropriate interpersonal style and calibrate their behavior to different contextual demands. This study highlights the role of the individual in the ambidexterity process by introducing the concept of influence tactic ambidexterity, to denote the frequent use of both hard and soft influence and investigating its role on task performance. Drawing on the literature on ambidexterity and HRM, we analyze data from a sample of 172 middle managers and their corresponding 68 supervisors working for multinational organizations, and provide evidence that influence tactic ambidexterity relates to higher levels and less variation in managers’ task performance compared to the sole use of either hard or soft tactics. Our findings also show that political skill positively moderates the relationship between influence tactic ambidexterity and a manager’s task performance. Therefore, this study suggests that influence tactic ambidexterity and political skill can be considered valuable HR assets for managers.     

Gibrat’s law and persistence of growth in Greek manufacturing

This study makes use of a sample of Greek manufacturing firms during 1995–2001 in order to analyze Gibrat’s law. We find Gibrat’s law is rejected for the total sample of firms, since persistence of growth plays a key role. The classification of firms in size and age groups, however, yields more interesting results: Gibrat’s law is rejected for micro, small, and young firms, since an inverse relationship between firm growth and initial firm size is found along with a persistence of growth rates in subsequent periods. In contrast, Gibrat’s law is accepted for medium, large, and old firms, implying that the growth patterns of these categories follow a random walk and do not tend to persist in subsequent periods.     

Is There a Gold Social Seal? The Financial Effects of Additions to and Deletions from Social Stock Indices

This study investigates the financial effects of additions to and deletions from the most well-known social stock index: the MSCI KLD 400. Our study makes use of the unique setting that index reconstitution provides and allows us to bypass possible issues of endogeneity that commonly plague empirical studies of the link between corporate social and financial performance. By examining not only short-term returns but also trading activity, earnings per share, and long-term performance of stocks that are involved in these events, we bring forward evidence of a ‘social index effect’ where unethical transgressions are penalized more heavily than responsibility is rewarded. We find that the addition of a stock to the index does not lead to material changes in its market price, whereas deletions are accompanied by negative cumulative abnormal returns. Trading volumes for deleted stocks are significantly increased on the event date, while the operational performances of the respective firms deteriorate after their deletion from the social index.     

Ascending Combinatorial Auctions with Risk Averse Bidders

Ascending combinatorial auctions are being used in an increasing number of spectrum sales worldwide, as well as in other multi-item markets in procurement and logistics. Much research has focused on pricing and payment rules in such ascending auctions. However, recent game-theoretical research has shown that such auctions can even lead to inefficient perfect Bayesian equilibria with risk-neutral bidders. There is a fundamental free-rider problem without a simple solution, raising the question whether ascending combinatorial auctions can be expected to be efficient in the field. Risk aversion is arguably a significant driver of bidding behavior in high-stakes auctions. We analyze the impact of risk aversion on equilibrium bidding strategies and efficiency in a threshold problem with one global and several local bidders. Due to the underlying free-rider problem, the impact of risk-aversion on equilibrium bidding strategies of local bidders is not obvious. We characterize the necessary and sufficient conditions for the perfect Bayesian equilibria of the ascending auction mechanism to have the local bidders to drop at the reserve price. Interestingly, in spite of the free-riding opportunities of local bidders, risk-aversion reduces the scope of the non-bidding equilibrium. The results help explain the high efficiency of ascending combinatorial auctions observed in the lab.     

The wage curve before and during the Greek economic crisis

Using cross-sectional data from the Labour Force Survey, we investigate whether a wage curve, i.e. a negative relationship between real wages and regional unemployment, could be estimated in the Greek labour market and in the period 1999–2014. Adopting individual static and regional dynamic specifications, our results do not support the existence of such a relationship despite the extensive macroeconomic adjustment of real wages after 2009. However, allowing for period-specific heterogeneous slopes, we find that a negative relationship between wages and regional unemployment emerged in the period 2010Q2–2011Q4 which however was short-lived. This relationship appears to be exclusively due to the restructuring of the collective bargaining regime and the reduction in the national minimum wages, both of which were implemented in the private sector.     

Saving out of different income categories in Greece

The aim of the present paper is to investigate whether in the case of Greece and within the framework of the existing national accounting system, significantly different marginal propensities to save are attached to different income categories. We establish that the marginal propensity to save out of property income is significantly higher, in fact double, than the marginal propensity to save out of agricultural income and income from wages and salaries of the other sectors of the economy.     

Contracts,the Spot Market Wage and Unemployment Benefits

This paper presents a model of the labour market with a contract and a spot market sector. Contracts are binding and enforceable, but unemployed contract workers are free to work in the spot market. The contracting wage is shown to be constant across states. A non‐trivial result shows that the spot market wage is increasing with product price. An increase in product price has an ambiguous effect on contract employment. An increase in unemployment benefits increases the contracting sector wage whilst stabilizing the spot market wage, and may have ambiguous effects on unemployment.
