South African consumers' opinions and beliefs regarding the health benefits of soy and soy products

Studies linking diet and health and consumers' demand for health information, has led to an increasing awareness of the role of nutrition in health and disease. Interest in soy foods and an awareness of its health benefits has also increased. The objective was to assess South African (SA) consumers' opinions and beliefs regarding the health benefits of soy and soy products using different statements. This cross‐sectional study randomly selected 3001 respondents from metropolitan and rural areas in South Africa. Data of 81% of respondents (n = 2437), who had heard of soy, were used. Trained fieldworkers administered questionnaires as face‐to‐face interviews. Fifteen statements probing consumers' opinions regarding the health benefits of soy were used. The data were weighted to be representative of the total South Africa adult population (n = 18 251 000) based on gender, age, living environment and race distribution in 2000. Effect sizes were used to determine the strength of associations (practical significance), since statistical significance could be attributed to the large study population. No practically significant differences between either gender or age groups, or between rural and metropolitan respondents' opinions were found. Most respondents in the total study population (50–75%), as well as within all race groups agreed that soy has many health benefits; soy is good for you; soy lowers cholesterol; soy is good for people with a milk allergy; soy helps keep your heart healthy; soy is good for diabetes and soy is good for growing children. Medium to large practically significant differences were found between racial groups regarding some of the statements. Practically significantly more adult Black consumers believed that soy is only for people with a low‐income, and fewer that soy milk is good for people with a milk allergy than did White, Indian and Coloured consumers. Whites were relatively more positive towards the use of soy for people with a milk allergy opposed to Blacks, while Blacks were relatively more positive than Whites towards the statement that soy helps keep your bones strong. The results indicate that SA consumers held positive opinions and associate consumption of soy with several health benefits. The role of soy is seen more as being preventative than curative. It may represent a challenge to the food industry to design soy‐containing products that appeal to a broader spectrum of consumers.     

Deficit reduction: Short-term pain for long-term gain

The paper evaluates the costs and benefits of fiscal consolidation using simulations based on the IMFs global dynamic general equilibrium model GIMF. Over the longer run, well-targeted permanent reductions in budget deficits can lead to a considerable increase in both the growth rate and the level of output. The gains may be enhanced by shifting some of the tax burden from incomes to consumption. In the short-run, credibility plays a crucial role in determining the size of initial output losses. Global current account imbalances would be significantly reduced if budget consolidation was larger in countries with current account deficits.     

General budget support as an aid instrument—impact on economic growth

Since the change of the new millennium, general budget support (GBS) has become a prominent, yet controversial and heavily debated, modality for delivering aid. We study GBS as an aid instrument from a cross‐country perspective. We examine if any growth impacts can be identified as a result of the use of GBS. We use data covering nine 4‐year intervals from 1976 to 2011. We modify two supply‐side IV strategies from previous aid–growth literature. In our main approach, we employ an interaction of an exogenous supply‐side variable (donor government fractionalization) and an endogenous variable (probability of receiving GBS) as an instrument for GBS, and in the alternative approach we construct an instrument following a supply‐side approach. Our results suggest that GBS receiving countries have grown faster than countries receiving other types of aid. Selection bias does not explain this result. The growth effect is not only attributed to lagged GBS but also to contemporaneous GBS flows.     

Decision Modelling: An Objective Approach to Moral Reasoning

All agree that moral issues are difficult issues mired in philosophical, political, social, and spiritual values. It's no wonder that the process of calculating moral positions has been likened to ``eating broth with a fork.'' While insuring moral behavior is difficult, teaching moral reasoning, a noble act, is even more difficult – especially when confronted by students who, by nature or discipline, are essentially objectivists dependant upon a need to structure what most will agree defies structure. This paper suggests one way the use of decision modeling may reach to moral objectivists in a classroom setting.     

The future of cooperation between the EU and ACP countries

Something over 20 years after the first Lomé Agreement came into force, most of the ACP countries are still among the poorest in the world. Why have these countries' situations not improved despite the Agreements? Why has their share of total EC imports from developing countries fallen in spite of the tariff preferences they are granted? What conclusions ought to be drawn for future cooperation between the EC and ACP countries?     

Does Aid Improve Public Service Delivery?

The expected increase in aid to Africa will put a big challenge for public service delivery. This paper provides an analysis of the effects of the volume and volatility of aid on education, health, water and sanitation outcomes, taking also into account the institutions related to public service delivery, including freedom of press, corruption, and decentralization, using a simultaneous equation model. Overall the share of Official Development Assistance (ODA) that is provided for education and health seems to have a positive impact on outcomes in these sectors, whereas total aid seems to be negatively associated. Aid volatility is associated with better outcomes in sanitation, water, and infant mortality, contrary to expectations. JEL no. H4, H5, H7, I1, I2, L9, O2     

Global effects of fiscal stimulus during the crisis

The IMF's Global Integrated Monetary and Fiscal Model is used to compute short-run multipliers of fiscal stimulus measures and long-run crowding-out effects of higher debt. Multipliers of two-year stimulus range from 0.2 to 2.2 depending on the fiscal instrument, the extent of monetary accommodation and the presence of a financial accelerator mechanism. A permanent 10 percentage point increase in the US debt to GDP ratio raises the US tax burden and world real interest rates in the long run, thereby reducing US and rest of the world output by 0.3-0.6 percent and 0.2-0.3 percent, respectively.
