Exploring the effects of leaders’ individualized consideration in extreme contexts

Abstract

Role clarity and trust in leadership are two crucial factors supporting soldiers in coping with uncertainty and imperfect knowledge. The present study examined the effects of leaders’ individualized consideration on both factors in a sample composed of 161 paratroopers from a parachute division of the NATO Airborne Forces. Conditional process modeling revealed that (1) leaders showing individualized consideration increase followers’ role clarity and, in parallel, develop a trusting relationship with them; (2) critical upward communication and perceived workload mediated and moderated these relationships, respectively. The implications of these findings for safety research and their practical applications are outlined.     

Robust martingale selection problem and its connections to the no‐arbitrage theory

We analyze the martingale selection problem of Rokhlin in a pointwise (robust) setting. We derive conditions for solvability of this problem and show how it is related to the classical no‐arbitrage deliberations. We obtain versions of the Fundamental Theorem of Asset Pricing in models spanning frictionless markets, models with proportional transaction costs, and models for illiquid markets. In all these models, we also incorporate trading constraints.     

Appropriate technology in a Solovian nonlinear growth model

We propose a Solovian growth model with a convex–concaveproduction function and international technological spillovers.We test the empirical implications of the model, analysing theeffects of the productivity slowdown that followed the oil shocksof the 1970s. We argue that this slowdown, altering the worldincome distribution, affected the pattern of international technologicalspillovers, taking the poorest countries further away from thetechnological leaders, and therefore unable to exploit theirtechnologies. The result is the emergence of a poverty trapfor low-income countries.     

R&D and performance persistence: Evidence from the United Kingdom

There is compelling evidence from both the United States and United Kingdom suggesting that R&D investment is positively related to operating and/or market performance. This study extends prior research on R&D and valuation by further examining the sustainability or persistence of operating growth and market performance as a result of R&D investments.We use a large dataset of U.K. companies during the period 1990–2003 and our findings confirm the relation between R&D intensity and consistent growth in Sales and Gross Income, but only in the cases when a firm needs to engage in R&D activity because of the industry in which it operates. Moreover, our evidence indicates not only a positive relation between R&D intensity and subsequent risk-adjusted excess returns among firms that engage in R&D as testified by prior literature, but we also show that R&D intensity improves persistence in excess stock returns: the highest R&D-intensity firms are found to earn higher risk-adjusted excess returns more consistently than the sample median return, compared to lower R&D-intensity firms, as well as firms with no R&D. We interpret this finding as consistent with at least some form of market mispricing.     

An alternative graphical modeling for economics: Econographicology

The rationale of Econographicology revolves around the efficacy of multidimensional graphs as the most effective visual tool to understand any economic phenomenon from a multidimensional view. The main motivation behind the creation of Econographicology is to evaluate multidimensional graphs evolved so far in economics and to develop new type of multidimensional graphs to facilitate the study of economics, as well as finance and business. Thereby, the mission of Econographicology is to offer academics, researchers and policy maker’s an alternative multidimensional graphical modeling approach for the research and teaching–learning process of economics, finance and business from a multidimensional perspective. Hence, this alternative multidimensional graphical modeling approach is offer a set of multi-dimensional coordinate spaces to build different types of multidimensional graphs to study any economic phenomenon. The following new types of multi-dimensional coordinate spaces are presented: the 5-dimensional coordinate space (vertical position and horizontal position), the mega-dynamic disks coordinate space (vertical position and horizontal position), and the mega-disks networks mapping.     

Claims frequency modeling using telematics car driving data

We investigate the predictive power of covariates extracted from telematics car driving data using the speed-acceleration heatmaps of Gao, G. & Wüthrich, M. V. [(2017). Feature extraction from telematics car driving heatmaps. SSRN ID: 3070069]. These telematics covariates include K-means classification, principal components, and bottleneck activations from a bottleneck neural network. In the conducted case study it turns out that the first principal component and the bottleneck activations give a better out-of-sample prediction for claims frequencies than other traditional pricing factors such as driver's age. Based on these numerical examples we recommend the use of these telematics covariates for car insurance pricing.     

Korean unification prospects: an assessment through the BDN-model

The debate on the possible unification of South Korea and North Korea has often been assessed from the economic perspective, which is insufficient since unification entails not only the integration of two economies but political, social and technological integration of two territories. Using the box negotiation diagram model, this paper expands the scope of the study on South Korea and North Korea unification through a multidisciplinary approach encompassing the political, economic, social and technological perspectives. Given the huge imbalanced points of unification drawn from our analysis, we observed more divergence than convergence hence, hinging the possibility of unification of serious negotiation.     

The Role of Spiritual Well-Being and Materialism in Determining Consumers’ Ethical Beliefs: An Empirical Study with Australian Consumers

A survey was conducted to investigate the relationship of Australian consumers’ lived (experienced) spiritual well-being and materialism with the various dimensions of consumer ethics. Spiritual well-being is composed of four domains—personal, communal, transcendental and environmental well-being. All four domains were examined in relation to the various dimensions of consumers’ ethical beliefs (active/illegal dimension, passive dimension, active/legal dimension, ‘no harm, no foul’ dimension and ‘doing good’/recycling dimension). The results indicated that lived communal well-being was negatively related to perceptions of the active/illegal dimension and the passive dimension and was positively related to perceptions of the ‘no harm, no foul’ dimension and the ‘doing good’/recycling dimension. Lived personal well-being was negatively related to perceptions of the active/illegal dimension and was positively related to perceptions of the ‘no harm, no foul’ dimension and the ‘doing good’/recycling dimension. Lived transcendental well-being was negatively related to perceptions of the passive dimension, the active/legal dimension and the ‘no harm, no foul’ dimension. Lived environmental well-being was negatively related to perceptions of the active/legal dimension and the ‘no harm, no foul’ dimension. The findings also indicated that materialism was positively associated with perceptions of actively benefiting from illegal actions, passively benefiting at the expense of the seller, actively benefiting from questionable but legal actions and benefiting from ‘no harm, no foul’ actions. Public policy implications of the findings and opportunities for future research are discussed.     

The Engines of Inequality

In Europe and in the United States, one of the legacies of the economic and financial crisis will no doubt be a high and particularly worrying level of economic inequality. Inequality has roots that go well beyond the 2008 collapse, but the stagnation that has followed it has made disparities in income and wealth more serious and more difficult to eradicate. The challenge now is to turn the injustice of current inequality into a theme of public mobilisation and political action.
