ABSTRACT

Street homelessness in the City of Tshwane was brought to public attention in the winter of 2014. This led to a composite research project involving different constituencies, including homeless people, to reflect on ways of addressing street homelessness in the city. This article serves as a conceptual and epistemological introduction to this collaborative research project entitled Pathways Out of Homelessness. The article argues for the use of a broad working definition of street homelessness that allows for complexities of homelessness to emerge, in order to discern diverse and appropriate alternatives.  相似文献

Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level data set on the foreign activities of German firms to test whether foreign activities are affected by business cycle developments. We aggregate the data by the sector of the reporting firm, the sector of the foreign affiliate, and the host country. Data are annual and cover the period 1989–2002. We find that German outward FDI increases in response to positive cyclical developments abroad and in response to a real depreciation of the domestic currency. JEL no. E3, F23  相似文献

Summary  This paper documents life cycle (or age) profiles of (log) household income, durable and non-durable consumption for Dutch households after explicitly controlling for time (or business cycle) effects and birth cohort effects. We find that both measures of consumption as well as income is clearly hump shaped over the life cycle. Hence, real consumption per household seems to track income over the life cycle. This empirical regularity is hard to reconcile with basic specifications of the life cycle model. We further document life cycle profiles of demographic and labor supply variables. We argue that part, but not all, of the hump in consumption may be explained by household composition variables. Durable consumption per adult equivalent stays approximately flat until age 60 after which it drops dramatically. This phenomenon may be partly explained by a decrease in work related durable expenditures after retirement. Non-durable consumption per equivalent adult increases steadily until age 55 and stays approximately flat after that.   相似文献

This article reports on a symposium held at Fort Hare University in July 1998. Its objective was to assess the current state of knowledge on communal rangelands and identify issues important for policy making. This was done in the light of concerns about recent policy reform. Uncontrolled access to resources and the lack of services were identified as the main constraints on socio‐economic development in the communal rangelands, and inadequate forage during the dry season was recognised as a general constraint on livestock production, irrespective of mean annual rainfall. Government policies must recognise these issues and the social and ecological heterogeneity of communal rangelands in South Africa. The conclusion with the most far‐reaching implications, however, was that degradation has occurred in some, but not all, communal rangelands and is most likely to occur in arid areas. This finding is in direct contrast to the current base for agricultural policies in South Africa, which assumes that livestock have little impact on rangelands.  相似文献

This article suggests a pricing model for commodities used to produce biofuel. The model is based on the concept that the deterministic component of the Wiener process is not constant and depends on time and exogenous variables. The model, which incorporates theory of storage, the convenience yield and the seasonality of harvests, was applied in the Brazilian sugar market. After predictions were made with the Kalman filter, the model produced results that were statistically more accurate than those returned by the two‐factor model available in the literature.  相似文献

In the context of the Partnership Agreements between the European Union (EU) and the African, Caribbean, and Pacific countries, this study estimates ad valorem tariff equivalents of European food safety standards on imports of key horticultural and fish products from Kenya, Tanzania, Uganda, and Zambia. The study uses an extension of the price‐wedge method to account for imperfect substitution and factor endowment in monopolistic competition. The estimated tariff equivalents are 55% and 98% for imports of fresh peas from Zambia to the Netherlands and the U.K., respectively. They range from 39% to 64% for imports of green beans and avocados from Kenya and from 63% to 270% for imports of frozen fish fillets in EU countries from the East African Community. We also observe large variations in tariff equivalents for the horticultural and fish products over time and EU importing countries.  相似文献

We study the effects of the Internet on regional price differences. Comparing two Dutch regions, we find that before the rise of the Internet, price differences of used cars between those regions amounted to some 11–15%, controlling for mileage, age, fuel type and engine volume. These price differences have completely disappeared after the rise of the Internet, in particular a website that allows consumers to make detailed comparisons between almost all used cars for sale in the Netherlands.  相似文献

When accepting the Maastricht treaty, the members of the Euro-zone agreed on the establishment of a very independent European Central Bank (ECB). Over the years, however, French political leaders systematically brought forward proposals undermining the ECB’s independence, much to the dismay of their German counterparts. This pattern of political disagreement on central bank independence has again surfaced during the current sovereign debt crisis, and has contributed to the discord amongst the Euro-zone members on the causes and proper solutions to the problems. This article conducts tests of various factors generally expected to influence the preference for central bank independence. It shows that economic explanations are unable to account for the persistent differences amongst European member-states on this issue. In contrast, national differences in political and economic culture and especially a nation’s score on the dimension Power Distance—its acceptance of centralisation of power in political leaders or institutions—does show a correlation with the different levels of internalisation of the norm of central bank independence. These findings show that institutionalisation of economic norms does not imply their internalisation by the political and the economic elite. In the broader context of current European politics, this may mean that even if European leaders will be able to come up with a common institutional answer to the current crisis, more profound convergence of their underlying economic and political cultures is needed for the successful and sustainable implementation of these solutions.  相似文献
