Are we living at the expense of the developing countries?

The industrial nations are often accused of achieving their relative affluence by using natural resources at the expense of the developing countries. Is this accusation justified? Would it really be in the developing countries' interests if the industrial nations drastically reduced their consumption of natural resources, as is so often demanded?     

A cluster analysis of commercialisation of farmers in developing rural areas of South Africa

The purpose of this article is to classify farmers in developing rural areas according to their commercial orientation and to evaluate their distinguishing characteristics. Farmers in these areas use both farm and non‐farm activities to commercialise to some degree. The aim of the commercialisation strategy is to generate income for acquiring other basic goods and services. A cluster analysis of 392 households surveyed in 1987 in the former KaNgwane identified seven groups of farming households: very low commercial households, moderately commercial households, high agricultural commercial households, livestock commercial households, non‐farm income households, non‐farm and agricultural commercial households and highly commercial households. The characteristics of four of these groups were investigated further. The current status of the commercialisation process suggests several policy directions: food security programmes should be aimed at those lacking resources, who may also be threatened by food shortages; emerging farmers with limited resources should be encouraged to diversify their income‐generating activities ‐ they should be given support (including access to land, markets, credit and management) to encourage them to prosper; and the progressive farmers require enhanced programmes to sustain their competitiveness.     

An economic analysis of the East Asia crisis

Since the summer of 1997, the East Asian “tiger” nations have suffered an unprecedented bout of weakness, plunging what had been vigorously expanding economies into a deep crisis. A number of domestic economic problems joined forces with turbulence on the foreign exchanges to generate a crisis of confidence on a grand scale. The crisis was triggered off by fundamental imbalances, with a key role being played by the “moral hazard” effect: domestic enterprises had been backed by implicit state guarantees, and it was always assumed that the IMF would assist if necessary. Then a destabilizing wave of speculation ran through the financial markets, pushing even countries with sound economic structures into difficulties. This article highlights the sequence of developments in the East Asian crisis, providing an economic explanation of the phenomenon.     

The Timing of Redistribution

We investigate whether late redistribution programs that can be targeted toward low income families, but that may distort savings decisions, can “dominate” early redistribution programs that cannot be targeted as a result of information constraints. We use simple two‐period overlapping generations models with heterogeneous agents under six policy regimes: a model calibrated to the U.S. economy (benchmark), two early redistribution (lump sum) regimes, two (targeted) late redistribution regimes, and finally a model without taxes and redistribution. Redistribution programs are financed by a labor tax on the young generation and a capital tax on the old generation. We argue that if the programs are small in size, late redistribution can dominate early redistribution in terms of welfare but not in terms of real output. Better targeting of low income households cannot completely offset savings distortions. In addition, we find that the optimal transfer and tax policy implies a capital tax of 100% and transfers exclusively to the young generation.     

Voluntary carbon offsetting and consumer choices for environmentally critical products—An experimental study

Purchases of voluntary carbon offsets (VCOs) are growing tremendously. At the same time, the number of activities and products for which VCOs are available is increasing. Experts discuss whether offering VCOs is exclusively associated with positive effects on the environment or if it instead may lead to increased consumption of environmentally critical products. To date, empirical evidence on such adverse effects is scarce. Therefore, this study uses a randomized controlled trial design to investigate how the availability of VCOs affects consumers' choices for environmentally critical products. The results suggest that when VCOs are available, the likelihood of environmentally critical consumption increases. From a mental accounting perspective, our findings support the theoretical rationale of VCOs as an instrument for moral licensing. Additionally, our results indicate that individuals tend to trivialize the harmfulness of the environmentally critical product and overestimate the effectiveness of VCOs for environmental protection, which we consider strategies for reducing cognitive dissonance and guilt.     

Human capital accumulation and endogenous public expenditures

In this paper, we present an overlapping-generations model, where individuals accumulate human capital through formal schooling. We model the role of the public sector in schooling as one of collecting taxes from households and providing inputs to the learning technology. Public expenditures on schools are determined endogenously. Under plausible restrictions, our model's predictions qualitatively match the observations on schooling, public expenditures on education, and student-teacher ratios. JEL Classification: E13, E62.
Accumulation de capital humain et dépenses publiques endogènes. Dans ce mémoire, les auteurs présentent un modèle de générations qui se chevauchent où les individus accumulent du capital humain via l'éducation formelle. Le rôle du secteur public dans l'éducation est défini comme celui de collecteur d'impôts auprès des ménages et de fournisseur d'intrants dans la technologie d'apprentissage. Les dépenses publiques en éducation sont déterminées de manière endogène. A partir de restrictions plausibles, les prédictions du modèle s'arriment qualitativement aux observations sur le monde scolaire, aux dépenses publiques en éducation, et aux ratios élèves/enseignants.     

Currency movements within and outside a currency union: The case of Germany and the euro area

In this paper, we analyse the volume of euro banknotes issued by Germany within the euro area with several seasonal methods. We draw a distinction between movements within Germany, circulation outside Germany but within the euro area and demand from non-euro-area countries. Our approach suggests that only about 20% of euro notes issued by Germany are used for transactions in Germany. The rest is hoarded (10%), circulates in other euro area countries (25%) or is held outside the euro area (45%).     

Providing for Organizational Memory in Computer-Supported Meetings

Meeting memory features are poorly integrated into current group support systems (GSS). In this article, I discuss how to introduce meeting memory functionality into a GSS. The article first introduces the benefits of effective meetings and organizational memory to an organization. Then, the following challenges to design are discussed: How to store semantically rich output, how to build up the meeting memory with a minimum of additional effort, how to integrate meeting memory into organizational memory, and how to protect the privacy of the meeting participants. Finally, using the group-object object-oriented model of a GSS, the article shows how meeting memory functionality can be implemented in a GSS.
