Ethics and Executive Coaching: An Agency Theory Approach

In recent years executive coaching has become an important management development practice in many organizations. Executive coaching is a partnership between a management level client and a coach hired by an organization to assist the executive in becoming a more effective and successful manager. While executive coaching has become a frequent and important practice in organizations, there has been relatively little serious consideration of the complex ethical issues that arise for persons and organizations. This study proposes that executive coaching involves an agency relation with specific moral duties that go beyond the usual standards of professional ethics. Agency theory, and in particular a focused understanding of the agency relationship, can provide a needed ethical grounding and basis for moral thinking about executive coaching.     

The Breakdown of Idiosyncratic Volatility Into Expected and Unexpected Components and Its Effects on Stock Returns in Brazil

Based on studies of idiosyncratic volatility developed in the recent literature, this study analyzes its relation with expected returns through the breakdown of idiosyncratic volatility in the Brazilian stock market and presents evidence of the importance of expected idiosyncratic volatility for asset pricing. We study the impact of the expected and unexpected components of idiosyncratic volatility on the returns of shares listed on the BOVESPA between 2004 and 2011. The results show a strong positive and significant relation between expected idiosyncratic volatility and returns. This evidence is highlighted when we use unexpected idiosyncratic volatility to control for unexpected returns. Additional robustness tests, controlling for size and momentum effects, also have positive and significant coefficients, corroborating previous findings.     

Customer demotion in hierarchical loyalty programmes

Hierarchical loyalty programmes are popular in many service industries, as a means to tie customers to the company and improve customer relationships. In these programmes, customers obtain more benefits if they spent more but are demoted if they spent less. This study focuses on demotion and suggests that customer demotion can have an asymmetrical negative effect on customers' trust, commitment, and loyalty. The effect appears strongest for demoted customers with an external locus of causality. An experimental study also shows that customer loyalty is lower for demoted customers than for customers who were never elevated.     

Humorous coping scales and their fit to a stress and coping framework

The focus of this study is on the fit between the item content of scales measuring humorous coping and basic concepts of stress and coping theory. To investigate this fit 81 items from seven currently available humorous coping scales have been subjected to a facet analysis, using the tool of a mapping sentence. Three facets derived from stress and coping theory were part of this mapping sentence: external demands, humorous responses and coping aims. Because of the claim that humorous coping may be related to physical health dimensions, special attention has been paid to two health-related coping aims: cognitive reappraisal and response-focused coping responses. Five raters categorized the facets and their respective categories. Some humorous coping scales showed an underrepresentation of “external demands” and “humorous responses” and only a few scales covered the “aims” facet adequately. Reliability and agreement parameters varied considerably among scales, both on facet level and on category level. The Waterloo University Humor Inventory (WUHI) was a positive exception to this pattern. Findings are discussed in the light of specific characteristics of the scales included. Possible improvements of humorous coping measurement in health-related research are proposed, as well as adaptations to the rating procedures.     

Institutions and economic performance: evidence from the labour market

We analyse the institutional determinants of economic performance,taking European labour-market institutions as a case in point.European economic growth after the Second World War was basedon Fordist technologies, a setting to which the continent'sinstitutions of solidaristic wage bargaining were ideally suited.They eased distributive conflicts and delivered wage moderation,which in turn supported high investment. The wage compressionthat was a corollary of their operation was of little consequenceso long as the dominant technologies were such that firms couldrely on a relatively homogeneous labour force. But as Fordismgave way to diversified quality production, which relied moreon highly skilled workers, the centralization of bargainingand the compression of wages became impediments rather thanaids to growth. Assuming that growth will rely even more inthe future on rapidly changing, science-based, skilled-labour-intensivetechnologies, countries with centralized labour-market institutionswill have to move still further in the direction of decentralization.Whether Europe in particular can accommodate these demands willhelp to determine whether it is able to re-establish a fullemployment economy in the twenty-first century.     

Changes in Technology and Preferences: A General Equilibrium Explanation of Rapid Growth in Trade

We use a computable general equilibrium model in an explanation of the recent rapid growth in Australia's trade, particularly intra-industry trade. Relative to previous studies of trade growth based on multiple regression analysis, our approach allows us to: (i) work at a detailed industry level; (ii) use primary variables to represent changes in technology and preferences rather than proxies; and (iii) use a framework based on explicit microeconomic foundations. We find that most of the growth in Australia's trade relative to GDP is explained by changes in technology and preferences.     

Institutional Bioeconomics and the Division of Labor: Reflections on Yarbrough & Yarbrough' Paper

The New Institutional Economics might have significant interactions with the economics of non-human societies. Some possibilities are considered in connection with the ideas of Yarbrough and Yarbrough on human societies. First, the need for enforcement may be less when the organisms in question treat one another as resources. Second, theories of the division of labor that have been developed in biology are applicable to human societies. There may be some interesting alternatives to traditional sociobiology as well.     

US elections and monthly stock market returns

Using monthly market returns over a period of 104 years, we investigate possible relationships between stock market performance and various occurrences in American elections. Unlike most prior studies, we find little relationship between the two. In the relatively few cases where we do find statistically significant relationships, the degree of explanatory power is quite small. Specifically, market returns do not appear to vary based on partisan control of the government, a result that is robust to the inclusion or exclusion of macroeconomic control variables. Further, the often-discussed “second-half” effect, which predicts higher returns during the second half of a given presidential term, turns out to be both weaker and less straightforward than is commonly believed. Overall, neither election results nor the election cycle appears to offer much help in predicting stock market returns.
