Sequential information arrival in the Finnish stock index derivatives markets

This paper investigates the hypothesis of sequential information arrival in the Finnish stock index futures and options markets. With no short selling restrictions in the derivatives markets, no causality relationships between returns and trading volume are observed. However, by using the so-called call-put signal, based on call and put volumes, causality between returns and volume is found supporting the hypothesis of sequential information arrival. In addition, it is discovered that the increased volume in stock index options relative to index futures has significantly increased their importance in the intermarket price discovery process.     

Building micro‐foundations for the routines,capabilities, and performance links

Micro‐foundations have become an important emerging theme in strategic management. This paper addresses micro‐foundations in two related ways. First, we argue that the kind of macro (or ‘collectivist') explanation that is presently utilized in the capabilities view in strategic management—which implies a neglect of micro‐foundations—is incomplete. There are no mechanisms that work solely on the macro‐level, directly connecting routines and capabilities to firm‐level outcomes. While routines and capabilities are useful shorthand for complicated patterns of individual action and interaction, ultimately they are best understood at the micro‐level. Second, we provide a formal model that shows precisely why macro‐explanation is incomplete and which exemplifies how explicit micro‐foundations may be built for notions of routines and capabilities and how these impact firm performance.

Modelling stock price behaviour by financial ratios

The main purpose of this study is to find out which economic dimensions of the firm are reflected in stock price behaviour in the Finnish stock market. Based on the previous theoretical articles, four economic dimensions are chosen: profitability, financial leverage, operating leverage and corporate growth. Twelve (12) financial ratios are then selected to represent these four dimensions. All the Finnish firms common series listed for the whole 1974–1986 period are included in the empirical analysis.All of the four expected dimensions above are found in the empirical classification pattern of ratios. On the cross-sectional level, profitability and financial leverate are reported as determinants of stock price behaviour. Corporation growth is merely connected to the risk of the common stock. Somewhat weaker results concerning the association between stock price behaviour and operating leverage factor may be due to difficulties measuring operating leverage on an empirical level.When studying the intra-year explanatory power of financial ratios, it is reported that the explanatory power of financial ratios tends to increase when the reporting day approaches, and starts to decrease after that releasing day of financial statement numbers. Empirical evidence strongly indicates that financial ratios represent pricing relationships in a substantive manner.The financial support by the Academy of Finland as well as the helpful comments and suggestions of an anonymous referee are gratefully acknowledged.     

Leadership Manipulation and Ethics in Storytelling

This article focuses on exerting influence in leadership, namely manipulation in storytelling. Manipulation is usually considered an unethical approach to leadership. We will argue that manipulation is a more complex phenomenon than just an unethical way of acting in leadership. We will demonstrate through an empirical qualitative study that there are various types of manipulation through storytelling. This article makes a contribution to the literature on manipulation through leadership storytelling, offering a more systematic empirical analysis and a more nuanced view of the topic than previously existed by outlining how managers engage in manipulative storytelling and what kind of ethics they link to their manipulation in leadership. Four types of manipulation in storytelling are identified in the study: humorous, pseudo-participative, seductive and pseudo-empathetic. From an ethical perspective, we will show that manipulation is not always self-evidently reprehensible. We will conclude that the dominant ethical justification for manipulation stems from its consequences.
