On the Theory and Practice of Water Regulation
No full textWe study water regulation for a schematic water economy representing a wide range of real world situations. A water policy has inter- and intra-temporal components. The first determines the limits on extractions from the naturally replenished sources, given the stochastic nature of recharge processes associated with uncertain precipitation. The intra-temporal regulation is concerned mainly with the allocating of the extracted and produced water among the end-users. The prices that implement the optimal intra-temporal allocation are derived. Regulation issues associated with cost recovery and asymmetric information are discussed.scarcity, pricing, optimal allocation, water economy, Resource /Energy Economics and Policy, C61, D82, Q11, Q25,
WELFARE MEASUREMENT UNDER THREATS OF ENVIRONMENTAL CATASTROPHES
No full textWelfare measures under threats of environmental catastrophes are studied using the "parable" apparatus of Weitzman and Lofgren [22]. The occurrence probability of the catastrophic event is driven (at least partly) by anthropogenic activities such as natural resource exploitation. Without external effects, the green NNP is a genuine welfare measure vis-à-vis a particular parable economy. Often, however, the occurrence hazard constitutes a public bad, treated as an externality by agents who ignore their own contribution to its accumulation. In such cases the green NNP, although accounting for the event hazard rate per se, fails to properly internalize future effects on the hazard rate of current economic activities and as a result overestimates welfare. The bias term associated with the green NNP is derived and expressed in a simply and interpretable form.green NNP, environmental catastrophes, hazard rate, uncertainty, Environmental Economics and Policy,
« Problème ethnique », par le professeur Yaron Tsur. Traduction commentée par Yann Scioldo-Zürcher Levi
No full textThis article is a translation from Hebrew into French of the paper, famous among Israeli historians, “Ethnic Problem” by Professor Yaron Tsur. Looking at the first Jewish ethnic riots that took place in 1959 in the city of Haïfa, the author details both the chronology that led to the Eastern migrants imposing themselves in the political landscape of the State, but also the social-political processes that that had, until then, forced them to live on the margins of Israeli society. This annotated translation is aimed at readers interested in Israeli Area Studies, but also for those who interest in the way populations are “structured” by one State created in the second half of the twentieth centur
RESOURCE EXPLOITATION, BIODIVERSITY LOSS AND ECOLOGICAL EVENTS
No full textWe study the management of a natural resource that supports ecosystems as well as human needs. The reduction in the resource base introduces a threat of occurrence of catastrophic ecological events, such as the sudden collapse of the national habitat that lead to severe loss of biodiversity. The event occurrence conditions involve uncertainty of various types, and the distinction among these types affects the optimal exploitation policies. When uncertainty is due to our ignorance of some aspects of the underlying ecology, the isolated equilibrium states characterizing optimal exploitation for many renewable resource problems become equilibrium intervals. Events triggered by genuinely stochastic environmental conditions maintain the structure of isolated equilibria, but the presence of event uncertainty shifts these equilibrium states relative to their position when occurrence conditions are known with certainty.ecosystem, resource management, event uncertainty, biodiversity, extinction, Resource /Energy Economics and Policy,
Translation Studies, Cultural Context, and Dante
No full textIn his article, Translation Studies, Cultural Context, and Dante, Reuven Tsur explores limits of legitimacy in translation studies. Tsur\u27s approach is a critique of the theoretical assumptions and their application in Edoardo Crisafulli\u27s cultural interpretation of Seamus Heaney\u27s decisions in translating the Ugolino episode in Dante\u27s Inferno. Crisafulli claims that Heaney\u27s choices show internal consistency, and can be accounted for by appealing to the Irish situational context. Instead, Tsur argues that Crisafulli\u27s cultural interpretations are arbitrary and that a more satisfactory account can be offered through an analysis of constraints within a conception of the aesthetic object as an elegant solution to a problem. Another disagreement concerns the intertextual processes between Dante\u27s segment and Heaney\u27s volume of original poetry in which it is printed. It is suggested here that by juxtaposing two texts, high-salient features of one text may reinforce similar features in the other and promote their salience
Uncertain Climate Policy and the Green Paradox
No full textUnintended consequences of announcing a climate policy well in advance of its implementation have been studied in a variety of situations. We show that a phenomenon akin to the so-called “Green- Paradox” holds also when the policy implementation date is uncertain. Governments are compelled, by international and domestic pressure, to demonstrate an intention to reduce greenhouse gas emissions. Taking actual steps, such as imposing a carbon tax on fossil energy, is a different matter altogether and depends on a host of political considerations. As a result, economic agents often consider the policy implementation date to be uncertain. We show that in the interim period between the policy announcement and its actual implementation the emission of green-house gases increases vis-`a-vis business-as-usual.Climate policy, carbon tax, uncertainty, green paradox, Environmental Economics and Policy, Resource /Energy Economics and Policy,
IRRIGATION PRODUCTION FUNCTIONS WITH WATER-CAPITAL SUBSTITUTION
No full textThe dynamics of biomass growth implies that the yield of irrigated crops depends, in addition to the total amount of water applied, on irrigation scheduling during the growing period. Advanced irrigation technologies relax constraints on irrigation rates and timing, allowing to better adjust irrigation scheduling to the varying needs of the plants along the growing period. Irrigation production functions, then, should include capital (or expenditures on irrigation equipment) in addition to aggregate water. We derive such functions and study their water-capital substitution properties. Implications for water demand and adoption of irrigation technologies are investigated. An empirical application confirms these properties.Resource /Energy Economics and Policy,
