Executives’ Orientations as Indicators of Crisis Management Policies and Practices*

ABSTRACT The paper examines effects of executives’ orientations on crisis management awareness and practices, drawing on the simplicity and paradox management theories. It is suggested that a focus on single‐sided management constitutes an antecedent of crisis proneness. Employing a set of key corporate domains and based on a holistic organizational approach, the study aims at assessing the extent to which companies are crisis prone or prepared. In a sample of 82 Istaeli business and not‐for‐profit organizations it was found that human resource management, strategy, structure, and unlearning factors significantly predicted crisis preparedness. These results suggest that unlearning, despite a mere allusion to this correlate in the simplicity and paradox management theories, correlates better with crisis preparedness. By contrast, traditional strategy‐related and structural effects were marginally related to crisis management policies. Implications and suggestions for further research are proposed.     

Will African Agriculture Survive Climate Change?

Measurement of the likely magnitude of the economic impact ofclimate change on African agriculture has been a challenge.Using data from a survey of more than 9,000 farmers across 11African countries, a cross-sectional approach estimates howfarm net revenues are affected by climate change compared withcurrent mean temperature. Revenues fall with warming for drylandcrops (temperature elasticity of –1.9) and livestock (–5.4),whereas revenues rise for irrigated crops (elasticity of 0.5),which are located in relatively cool parts of Africa and arebuffered by irrigation from the effects of warming. At first,warming has little net aggregate effect as the gains for irrigatedcrops offset the losses for dryland crops and livestock. Warming,however, will likely reduce dryland farm income immedia-tely.The final effects will also depend on changes in precipitation,because revenues from all farm types increase with precipitation.Because irrigated farms are less sensitive to climate, wherewater is available, irrigation is a practical adaptation toclimate change in Africa.

Interactions between electricity generation sources and economic activity in two Nord Pool systems. Evidence from Estonia and Sweden

The interactions between electricity sources and industrial production in Estonia and Sweden are analysed based on monthly data. The availability of data defines the time spans from January 2010 to September 2015 for Sweden and from April 2010 to December 2014 for Estonia. These countries are particularly interesting to study because of their dissimilar generation mix. Estonia’s generation mix is based on oil shale, while Sweden’s is based on nuclear plants and hydroelectricity. In short, both countries’ energy mixes are based on endogenous natural resources. The ARDL model was applied, allowing the long-run and short-run effects to be captured. The results prove that economic growth is sustained by natural endogenous resources. Estonia should continue to improve the usage of renewable energies, using fossil sources in support, in order to reduce emissions and to meet international environmental commitments. Sweden should promote the efficient usage of various renewable sources.     

Affect and persuasion: The influence of pleasantness and arousal on attitude formation and message elaboration

In contrast to past research that viewed affect as unidimensional, this study examines the effects of affect's two primary dimensions, pleasantness and arousal, on ad-based persuasion outcomes (attitude favorability) and processes (degree of elaboration, thought positivity). After assessing their naturally-occurring levels of pleasantness and arousal, subjects were exposed to a persuasive communication and assigned to an involvement (low/high) by message strength (low/high) design. GLM analyses revealed that higher pleasantness accentuated the typical involvement X message interaction on attitude favorability, and that higher involvement enhanced message elaboration only when accompanied by higher pleasantness. Path analyses further suggested that (1) higher pleasantness enhanced message elaboration under higher involvement but decreased it under lower involvement, (2) under higher involvement, both pleasantness and arousal positively impacted thought positivity, and, (3) higher arousal decreased message elaboration only for the weaker message. The importance and implications of a broader than unidimensional view of affect in persuasion are discussed. © 1997 John Wiley & Sons, Inc.     

Mechanization in land preparation and agricultural intensification: The case of rice farming in the Cote d'Ivoire

It is critically important to intensify farming systems in sub-Saharan Africa by disseminating improved agronomic practices and increasing the application of modern inputs. One of the region's problems is that proper land preparation is difficult due to the scarcity of draft animals and the underdevelopment of the tractor rental market. Our analysis of rice production in the Cote d'Ivoire reveals that farmers who use tractors in land preparation more intensively apply fertilizer and use more labor to carefully implement proper agronomic practices, thereby raising productivity. Thus, the diffusion of tractors appears to be key to the intensification of rice farming systems in sub-Saharan Africa.     

An Investigation into the Positive Effect of an Educated Wife on Her Husband’s Earnings: The Case of Japan in the Period between 2000 and 2003

We analyze the effect of a wife??s human capital on her husband??s earnings, using individual-level data for Japan in the period 2000?C2003. We find a positive association between a wife??s education and her husband??s earnings, which can be attributed to the assortative mating effect as well as the positive effect of an educated wife on her husband??s productivity. We divide the sample into those couples with non-working wives and those with working wives, and also employ an estimation strategy proposed by Jepsen (Review of Economics of the Household 3:197?C214, 2005), attempting to control for the assortative mating effect. Our regression analysis provides suggestive evidence that educated wives increase their husbands?? productivity and earnings only when they are non-workers and have sufficient time to support their husbands.
