Po-Ting Liu and Guang-Zhen Sun Abstract The implications of the international demonstration effect (IDE) for the development of underdeveloped economies have long been studied and debated. Yet few formal analyses exist in the literature, especially regarding its implications for the growth of domestic markets and the division of labour in developing economies. We offer an analysis of endogenous...

This article studies the influence of women’s work on the risk of divorce, using data from the Netherlands. We examine economic interpretations of the work effect by disentangling the work effect into five dimensions: (a) the intensity of wife’s work, (b) the status of wife’s work, (c) potential labour market success, (d) relative labour market success (vis-à-vis the husband), and (e) the divis...

As women’s involvement in the paid labour force increased, social researchers believed that this would transfer to an increase in men’s involvement in domestic labour. However, this has not been realised to any great extent (see Hochschild, 1989). Through the examination of different life course groups, this paper outlines responsibility for housework and childrearing tasks. This analysis finds...

background: misoprostol, a prostaglandin e1 analogue compared to prostaglandin e2, has the advantage of being inexpensive and stable at room temperature, with its proven efficacy and safety. however studies on the effect of ph on the efficacy of misoprostol have yielded conflicting results. thus its use in the induction of labour in patients with premature rupture of membrane requires further i...

Understanding the emergence and evolution of multicellularity and cellular differentiation is a core problem in biology. We develop a quantitative model that shows that a multicellular form emerges from genetically identical unicellular ancestors when the compartmentalization of poorly compatible physiological processes into component cells of an aggregate produces a fitness advantage. This div...

A computational model of a simple commodity economy is examined and a theory of the relationship between commodity values, market prices and the efficient division of social labour is developed. The main conclusions are: (i) the labour value of a commodity is an attractor for its market price; (ii) market prices are error signals that function to allocate the available social labour between sec...

The 'division of labour' model of eye evolution is elaborated here. We propose that the evolution of complex, multicellular animal eyes started from a single, multi-functional cell type that existed in metazoan ancestors. This ancient cell type had at least three functions: light detection via a photoreceptive organelle, light shading by means of pigment granules and steering through locomotor ...
