When is a market not a market?: 'exemption', 'externality' and 'exception' in the case of European State Aid rules

The reach of markets and market-based forms of valuation is never unlimited in any society, which invites empirical and political questions regarding how limits to markets are instituted, justified and enforced. Under neoliberalism, the state performs a key role in expanding the reach of markets and associated principles and techniques of valuation, using law and governmental techniques. But this then poses a question of the relationship between the neoliberal state and the market that it endorses and enforces: is the state internal or external to the market order that it helps to construct? European Union state aid rules provide an empirical entry point to consider such questions, providing a combination of normative, technical and sovereign principles, via which the division between state and market can be justified, tested and enacted. The article identifies three separate though overlapping logics within state aid documents, each of which offers the state a justification for suspending the competitive market order: exemptions, in which non-market values are upheld, externalities, in which markets are shown to be technically inefficient, and exceptions – such as the 2008 financial crisis – in which the state abandons the market to save the market

Is there competition among ciliates and nematodes?

Bergtold M, Gunther V, Traunspurger W. Is there competition among ciliates and nematodes? FRESHWATER BIOLOGY. 2005;50(8):1351-1359.1. Biotic interaction between the ciliate Cyclidium glaucoma and the nematode Caenorhabditis elegans was investigated by manipulating the densities of the organisms in microcosms with and without sediment. 2. After 11 days the abundance of ciliates, nematodes and bacteria as well as extracellular enzyme activity were determined. Ciliates had a negative effect on nematode abundance in microcosms without sediment and in microcosms with sandy sediment, whereas in muddy sediment the effect was less distinctive. An effect of nematodes on ciliates was not observed. 3. The common resource bacteria were not affected negatively by the activity of the grazers. Overall grazer biomass increased with the addition of sediment to the microcosms, suggesting a rise of the carrying capacity in the experimental system. Especially in muddy sediment the abundance of bacteria and extracellular enzyme activity was higher compared to the microcosms without sediment. 4. The results of the experiment suggest a strong interspecific competition between nematodes and ciliates, where nematodes are, at least temporary, strongly affected
