Expenditure patterns on food and non food items of Khayelitsha households,Western Cape,South Africa

Food insecurity or lack of access to adequate and nutritious food is a major determinant of under‐nutrition. Expenditure patterns accompanied by unemployment, low level of education, inflation and high food prices have a direct negative impact on food availability within households (Moller, 1997). Ghany and Schwenk (1993) found that as household income increases, the proportion of expenditures on food decreases, the proportion of expenditures on clothing, rent, fuel, and light stayed the same and that of sundries increased. The aim of this study was to investigate household expenditure patterns on food and non‐food items in Khayelitsha. A total of 20 households (10 from the formal and 10 from the informal settlements) were randomly selected from those willing to participate in the study. A questionnaire with open ended and closed questions was used to collect data. The questionnaire comprised four sections namely: biographical information, socio‐economic information which used wealth quintiles to assess households’ social economic status, total expenditure information and a food/hunger scale was used to assess households’ food availability. The findings revealed that households from informal settlements spent more money (62.2%) as a proportion of their income on food compared to households from the formal settlement (39%). There was higher unemployment rate (100%) at the informal settlement compared to the formal settlement (40%). Wealth quintiles scales did not reflect the social status of the households as equipment and assets owned by households were only used as fallback position during times of economic hardships. Households used different purchasing strategies; food and non‐food items were mainly purchased from outside the township (60%). Forty percent of the households bought their items from local shops and spazas because they allowed them to buy items whenever little money was available or to take items on credit. All the respondents preferred to buy bread and small items from spazas and local shops. Prices of items in the spazas and local shops were higher compared to prices of items in bigger shops outside the townships. The food/hunger scale and wealth quintiles showed that informal settlement households were more food insecure (as they were all unemployed and about 50% of the households ran out of food always) and had fewer assets compared to the formal settlement households. The implications of these findings underscore the need to improve socio‐economic conditions of low resource households through empowerment programs. These programs can be in the form of training in management/decision making, work related skills/literacy (to help them access formal employment), business management/income generation skills (to help them to be self‐employed), budgeting, and food gardening. This approach can help to increase the resource base and alleviate food insecurity in low resource households.     

Daylight saving effect

Kamstra et al. [Kamstra, M.J., Kramer, L.A., Levi, M.D., 2000. Losing sleep at the market: the daylight saving anomaly. The American Economic Review 90, 1005–1011] argue that the mean weekend return following the changes in daylight saving time is less than the mean weekend return throughout the rest of the year. Opposing studies, such as Pinegar [Pinegar, J.M., 2002. Losing sleep at the market: comment. The American Economic Review 92, 1251–1256), reason that the observed results depend upon methodology. We extend the ongoing discussions by providing further evidence for equity markets and bond markets in Germany and across Europe. We further demonstrate that the daylight saving effect does not serve as a potential rationale for the weekend effect.

A flight to Q? Firm investment and financing in Korea before and after the 1997 financial crisis

We examine investment behavior among exchange-listed Korean manufacturing firms before and after the 1997 financial crisis using firm-level panel data. Starting with the standard Q-theory of investment, we augment it by allowing for a sales accelerator and the possibility of cash constraints, categorizing firms based on their age, size and affiliation to an industrial conglomerate (i.e., chaebol). We find that Tobin’s Q is a robust determinant of investment in a pooled sample for 1992–2001, but that it became more important for small firms and less important for chaebol-affiliated firms after the crisis. Investment by chaebol firms also became more sensitive to the availability of internal cash balances after the crisis. We interpret this as reflecting a shift in the Korean economy to a stronger market orientation after the crisis and to a business climate in which the quality of potential projects became more important relative to capital market imperfections in determining the destination of investment funds.     

AN EMPIRICAL EXAMINATION OF RELATIONSHIP MAGNITUDE

Based upon a review of the extant literature, it is proposed that the structure of an interorganizational relationship is composed of relationship type and the under‐researched construct of relationship magnitude. Specifically, it is hypothesized that relationship magnitude, a second order construct composed of trust, commitment, and dependence, affects relationship type, which affects the perception of value of the relationship. The results of a survey analyzed through structural equation modeling support these hypotheses.     

The Effect of Earnings–Announcement Timing on Earnings Management

This paper examines whether firms which delay earnings announcements engage in earnings management. The cross–sectional version of the modified Jones 1995 model is used to estimate 'normal' accruals. Prior research has documented that, on average, delayed earnings announcements are associated with negative earnings surprises. Our evidence suggests that the market anticipates unfavorable earnings news when it observes reporting delays. As a consequence, late reporters appear to make the most of a bad situation by employing income–decreasing accruals in big–bath–type earnings management and in contractual renegotiations. We find that the magnitude of income–reducing abnormal accruals is related to the reporting lag.     

Comparative Advantage in Demand: Experimental Evidence of Preferences for Genetically Modified Food in the United States and European Union

The United States (US) exports more than US$6 billion in agricultural commodities to the European Union(EU) each year, but one issue carries the potential to diminish this trade: use of biotechnology in food production. The EU has adopted more stringent policies towards biotechnology than the US. Understanding differences in European and American policies towards genetically modified (GM) foods requires a greater understanding of consumers’ attitudes and preferences. This paper reports results from the first large‐scale, cross‐Atlantic study to analyse consumer demand for genetically modified food in a non‐hypothetical market environment. We strongly reject the frequent if convenient assumption in trade theory that consumer preferences are identical across countries: the median level of compensation demanded by English and French consumers to consume a GM food is found to be more than twice that in any of the US locations. Results have important implications for trade theory, which typically focuses on differences in specialization, comparative advantage and factor endowments across countries, and for on‐going trade disputes at the World Trade Organization.     

What Is Fair? Experimental Evidence

There has been growing interest within the economics discipline in the role of equity concerns in the distribution of resources. This paper presents empirical evidence from controlled laboratory experiments where third-party decision makers allocate resources between two individuals. The experimental results indicate that subjects view a wide range of different allocations as the fair distribution of resources. However, regression analysis indicates that both treatment effects and a few demographic variables explain some of this variation in fairness concepts. Most significantly, decision makers rewarded subjects who earned their favorable positions, and the gender of the decision maker was an important predictor of the allocation chosen.     

Who's in charge of the central city? The conflict between efficiency and equity in the design of a metropolitan area

A circular metropolitan area consists of a central city surrounded by a suburb. Households sort over the two jurisdictions based on public service levels and their costs of commuting to the metropolitan center. Using numerical simulations, we show that (1) there typically exist two equilibria: one in which the poor form the voting majority in the central city and the other in which the rich form the majority in the central city; (2) there is an efficiency vs. equity trade-off as to which equilibrium is preferred; and (3) if the central city contains only poor households, equity favors expanding the central city to include rich households. The third result arises not because of a fiscal subsidy from rich to poor households induced by a property tax but rather because of a change in house price capitalization.
