Changes in family food habits: the role of migration

The food habits of people generally dictate their nutritional well‐being, which subsequently affects their physical and mental health. A change in environment is one of the major factors that could bring about positive or negative changes in food consumption patterns. The food habits of 50 migrant families living in a suburb of Accra were studied to find out what changes have taken place as a result of a change in living environment. The homemaker in each family was interviewed to obtain information on socioeconomic characteristics, past and present food procurement and consumption patterns, food avoidances and factors that influence food selection and consumption. The findings revealed that, although the majority stuck to foods they were accustomed to, there were striking changes in sources of food procurement, the number of meals prepared at home and the relative frequency of consumption of some staple foods. One‐third of the study group felt that their diets had become poorer as a result of the change in environment. Two factors, time and money, were associated with the changes that had taken place. The study provides some evidence for the existence of inadequate diets among migrant families. This might even reflect a more serious situation facing the numerous migrant youth, who have no families to cater for them and, hence, put their health at risk. Home economists and other related professionals could be instrumental in drawing up intervention programmes to ensure adequate selection and consumption of food to promote good health among migrants to the city.     

X-Inefficiency,Competition and Market Information

Whether competition forces firms toward efficient behaviour is an open question. We consider a duopoly with firms run by managers and affected by adverse selection on costs. In contrast to recent literature, we point out that, to have a genuine effect on firm X-inefficiency, competition must change managerial incentives. By introducing the availability of some signal on the rivals' behaviour we show that, if costs are correlated, the contractual use of that signal can render private managerial information uninfluential. This result stresses the informational role of the market and suggests scope for future work.     

Countervailing power? Collusion in markets with decentralized trade

We consider the collective incentives of buyers and sellers to form cartels in markets with decentralized trade and pairwise bargaining. Cartels are coalitions of buyers or sellers that limit market participation and compensate inactive members for their abstention. In stable market outcomes, cartels set Nash equilibrium quantities and cartel memberships are immune to deviations. The set of stable market outcomes is non-empty and its full characterization is provided. Stable market outcomes are of two types: (i) at least one cartel restrains trade and market participation is balanced; (ii) only one cartel is active and it reduces trade slightly below the opponent’s.     

Combining creativity and control: Understanding individual motivation in large-scale collaborative creativity

Recent research has shown that management control systems (MCS) can improve performance in contexts characterized by high levels of task uncertainty. This seems to conflict with a second stream of research, which argues that MCSs risk undermining the intrinsic motivation needed for effective performance in such settings. To solve this puzzle, we build on theories of perceived locus of causality and self-construal and develop an integrative model summarized in 15 propositions. To explicate our proposed solution and to show its robustness, we focus on the class of activities we call large-scale collaborative creativity (LSCC) - contexts where individuals face a dual challenge of demonstrating creativity and embracing the formal controls that coordinate their creative activities with others’. We argue that LSCC requires the simultaneous activation of intrinsic and identified forms of motivation, and simultaneously independent and interdependent self-construals. Against some scholarship that argues or assumes that such simultaneous combinations are infeasible, we argue that they can be fostered through appropriate attraction-selection-attrition policies and management control systems design. We also show how our propositions can enrich our understanding of motivation in other settings, where creativity and/or coordination demands are less pressing.     

Kick‐starting diffusion: Explaining the varying frequency of preferential trade agreements’ environmental provisions by their initial conditions

Most recent preferential trade agreements (PTAs) include environmental provisions. While a number of these environmental provisions remain rare and are incorporated in just a few PTAs, others are widely popular and are duplicated in more than 100 PTAs. We still lack a convincing explanation for this varying frequency. While the diffusion literature typically tries to explain how diffusion occurs, we investigate why certain provisions diffuse more often than others. We hypothesise that the initial conditions under which provisions first emerge determine the scope of their diffusion. Our results support this hypothesis and indicate that provisions originating from intercontinental agreements diffuse more often than others. At the same time, provisions first designed by economically powerful or environmentally credible countries are not related to more frequent occurrences of diffusion. These findings are of interest for the literatures on international institutions' design, interaction and diffusion.     

Coastal Urban Planning in The ‘Green Republic’: Tourism Development and the Nature–Infrastructure Paradox in Costa Rica

This article examines coastal urban planning in Costa Rica vis‐à‐vis the country's values in the areas of sustainable tourism and community development, focusing on the city of Jacó. I argue that an anti‐urban tourism development strategy, swift coastal urban development and weak planning have nurtured a nature–infrastructure paradox: when people are brought closer to nature without proper urban and governmental infrastructure, this causes social and environmental damage. To assess this paradox and understand local perceptions of development, I analyzed lengthy semi‐structured interviews and survey responses in San José and Jacó in this study. Research methods also encompassed analysis of current tourism planning institutions and regulations, tourism media coverage and reports, real estate data, participant observation of planning and community meetings and activities, and observations of the built and natural environmental conditions in Jacó and its surroundings. The findings show jurisdictional fragmentation, regulatory weaknesses, complexity, poor coordination, slow action, and incoherent planning and development, leading to environmental degradation and socio‐spatial inequities. A more balanced approach to planning and development would seek to improve environmental health and socio‐spatial equity in tandem, by nurturing and advancing both nature and infrastructure development. Lessons from Jacó have global resonance, given the expansion of the worldwide tourism and second‐home/retirement‐housing industries, their recent concentration in urban coastal destinations of developing countries, and the fragility of these socio‐ecological systems.     

Growth, public investment and corruption with failing institutions

Corruption is thought to prevent poor countries from catching up with richer ones. We analyze one channel through which corruption hampers growth: public investment can be distorted in favor of specific types of spending for which rent-seeking is easier and better concealed. To study this distortion, we propose a dynamic model where households vote for the composition of public spending, subject to an incentive constraint reflecting individuals’ choice between productive activity and rent-seeking. In equilibrium, the structure of public investment is determined by the predatory technology and the distribution of political power. Among different regimes, the model shows a possible scenario of distortion without corruption in which there is no effective corruption but the possibility of corruption still distorts the allocation of public investment. We test the implications of the model on a set of countries using a two-stage least squares estimation. We find that developing countries with high predatory technology invest more in housing and physical capital in comparison with health and education. The reverse is true for developed countries.      

Arbitration systems and negotiations

We consider a model of bargaining by concessions where agents can terminate negotiations by accepting the settlement of an arbitrator. The impact of pragmatic arbitrators—that enforce concessions that precede their appointment—is compared with that of arbitrators that act on principle—ignoring prior concessions. We show that while the impact of arbitration always depends on how costly that intervention is relative to direct negotiation, the range of scenarios for which it has an impact, and the precise effect of such impact, does change depending on the behavior—pragmatic or on principle—of the arbitrator. Moreover the requirement of mutual consent to appoint the arbitrator matters only when he is pragmatic. Efficiency and equilibrium are not aligned since agents sometimes reach negotiated agreements when an arbitrated settlement is more efficient and vice versa. What system of arbitration has the best performance depends on the arbitration and negotiation costs, and each can be optimal for plausible environments.      

RELIGIONS,FERTILITY, AND GROWTH IN SOUTHEAST ASIA

We investigate the extent to which the pronatalism of religions impedes growth via the fertility/education channel. Using Southeast Asian censuses, we show empirically that being Catholic, Buddhist, or Muslim significantly raises fertility, especially for couples with intermediate to high education levels. With these estimates, we identify the parameters of a structural model. Catholicism is strongly pro‐child (increasing total spending on children), followed by Buddhism, whereas Islam is more pro‐birth (redirecting spending from quality to quantity). Pro‐child religions depress growth in its early stages by lowering savings and labor supply. In the later stages of growth, pro‐birth religions impede human capital accumulation.     

Advertising Spending,Mood and Level of Product Information on Quality Perception

The aim of this article is to investigate the influence of advertising spending and mood on consumers' perceived quality, considering scenarios with slight and severe information asymmetry as regards a product's attributes. An experimental study conducted with 385 subjects demonstrated that mood moderates the impact of advertising spending on consumers' perceived quality, specifically when these expenses are at and above the market average. Moreover, the impact of mood on perceived quality was moderated by the level of product information. These results have several theoretical and managerial implications, and may help companies to invest their advertising resources more efficiently. Copyright © 2015 John Wiley & Sons, Ltd.
