Strategic planning of complex economic systems ∗

A major drawback of conventional models of the behavior of economic systems (and derived tools for policy intervention) is that the desire for tractability leads generally to a high degree of abstraction from reality. This article suggests an alternative, and arguably complementary, approach which engages specifically with economic complexity. The technique used is one of interactive spatial modelling over long time periods where the principle economic agents base decisions on incomplete heuristic information. For illustrative purposes the model has been calibrated on the basis of Senegalese data for 1981–91 and broad generic equations presented. The article argues that such a methodological approach holds out considerable advantages for strategic planning of sustainable economic systems. In particular it permits the direct engagement of noneconomic disciplines and client stakeholders in the planning process.     

On Explaining Individual and Corporate Culpability in the Global Climate Change Era

Humans are causing global climate change (GCC), and such climate change causes harms. Robin Attfield explained how individuals should be understood to be culpable for these harms. In this paper, I use a critical analysis of Attfield’s explanatory framework to explore further difficulties in accounting for corporate responsibility for these harms. I begin by arguing that there are some problems with his framework as it is applied to individuals that emit greenhouse gases (GHGs). I then show that it will be very difficult to extend this framework to corporations. This is not a criticism of Attfield’s work (as he does not discuss corporate responsibility for those harms associated with GCC), but it will serve to show the difficulty in philosophically explaining corporations’ moral culpability when it comes to these harms. In fact, one positive conclusion of this paper is that it highlights a new area of concern that has been ignored in discussions of corporate responsibilities—that of mediated responsibilities—which is how Attfield understands our responsibilities regarding GCC. The discussion of this concern will draw attention to another positive conclusion of this paper: the harms associated with CO₂ are very unlike the harms associated with other airborne-emitted substances, which will indicate that we will need new ways of understanding how individuals and corporations are philosophically responsible for these harms. The final positive conclusion of this paper will be a discussion of what the constraints should be on new approaches to explaining our culpability.     

Tradable permit allocations and sequential choice

This paper investigates initial allocation choices in an international tradable pollution permit market. For two sovereign governments, we compare allocation choices that are either simultaneously or sequentially announced. We show sequential allocation announcements result in higher (lower) aggregate emissions when announcements are strategic substitutes (complements). Whether allocation announcements are strategic substitutes or complements depends on the relationship between the follower’s damage function and governments’ abatement costs. When the marginal damage function is relatively steep (flat), allocation announcements are strategic substitutes (complements). For quadratic abatement costs and damages, sequential announcements provide a higher level of aggregate emissions.     

“Social Security-Adequacy,Equity, and Progressiveness: A Review of Criteria Based on Experience in Canada and the United States,” Robert L. Brown and Jeffrey Ip,January 2000

Abstract

We consider an optimal dynamic control problem for an insurance company with opportunities of proportional reinsurance and investment. The company can purchase proportional reinsurance to reduce its risk level and invest its surplus in a financial market that has a Black-Scholes risky asset and a risk-free asset. When investing in the risk-free asset, three practical borrowing constraints are studied individually: (B1) the borrowing rate is higher than lending (saving) rate, (B2) the dollar amount borrowed is no more than K > 0, and (B3) the proportion of the borrowed amount to the surplus level is no more than k > 0. Under each of the constraints, the objective is to minimize the probability of ruin. Classical stochastic control theory is applied to solve the problem. Specifically, the minimal ruin probability functions are obtained in closed form by solving Hamilton-Jacobi-Bellman (HJB) equations, and their associated optimal reinsurance-investment policies are found by verification techniques.     

Further participatory adaptation is required for community leaders to champion conservation agriculture in Africa

There is a recognized need for the participation of local communities in designing and implementing agricultural interventions for the sustainable intensification in smallholder systems. This study examines the perspectives of local community leaders towards the widely promoted, but not widely adopted, practice of Conservation Agriculture (CA) in African smallholder systems. Perceptions from 47 community leaders (both from traditional local authorities and farmer organizations) across six African countries are documented regarding how CA matches the wants, needs and capabilities of farmers in their communities. While community leaders generally perceived CA as potentially beneficial, they also indicated that CA is not currently perceived as feasible within their communities and hence has limited relevance. Three key themes were identified that limit both CA use and sustainable intensification more generally: [1] a perceived reluctance of farmers to engage with the community platform as part of a higher input, market-oriented production system; [2] informational constraints due to non-functional exchange mechanisms; and [3] a lack of local adaptation of CA underscored by the persistence of top-down, linear research and extension approaches. Through greater understanding of local perspectives, a clearer picture emerges of the need for greater participatory engagement and local adaptation if sustainable intensification of African smallholder agricultural systems is to be achieved.     

Predictors of Usage Intentions of Pirated Software

The purpose of this study is to investigate the salient factors influencing consumers’ attitudes and usage intentions towards pirated software. Using the Theory of Planned Behaviour, this study investigates the relationships between three sets of factors, i.e. personal, social and perceived behavioural control onto attitudes towards pirated software. Through a multiple regression, only personal factors have shown significant relationship with attitudes towards software piracy. Further results from this study have supported that favourable attitudes towards pirated software is likely to result in stronger intentions to use pirated software. It was found that computer proficiency acts as a predictor for intentions towards pirated software, rather than a moderator as originally postulated.     

Watching the FIFA World Cup 2010 in England: the sojourner perspective

Recent years have seen an emergence of a varied academic literature focused on the football fan, with a wealth of studies exploring issues such as hooliganism, fan behaviour and fan identification. No research, however, has documented the experiences and perspectives of the international sojourner, who follows the televised tournament far away from the home country. This paper offers a contribution to the literature on fandom by focusing on the experiences of becoming a temporary fan among a sample of nine international students in England during the period of the 2010 FIFA World Cup. It shows the importance of the tournament for students away from their home nation, acting as a point of celebration and as a means of bringing sojourners of the same nationality together to support their team. It reveals how the tournament offered escape from stress, became a focal point for social interaction, provided the opportunity for recreation of home, and for the reinforcement of feelings of national identity.     

An Instrument to Measure the ‘Degree of Professionalism’ in a Professional Service

Professional services have received considerable attention. This article describes a scale to measure the degree of professionalism of both a profession and an individual pro- fessional and use of the scale to differentiate between two sub-groups of the medical profession: general practitioners and medical specialists. As expected, medical specialists were found to be more professional. Possible managerial uses of the scale are discussed.     

Investment in organization capital

We study a firm’s investment in organization capital by analyzing a dynamic model of language development and intrafirm communication. We show that firms with richer internal language (i.e., more organization capital) have lower employee turnover, and higher diversity in skill and wages among incumbents who are promoted from within the firm. Our results also suggest that firms in rapidly changing industries are less likely to invest in organization capital, and are more likely to have high managerial turnover. Finally, our model shows that employment protection regulations lead to more investment in organization capital but less innovation.
