Geographic Variability of Sea-Level Change
No full textLocal sea-level changes differ significantly from global-mean sea-level change as a result of (1) non-climatic, geological background processes; (2) atmosphere/ocean dy- namics; and (3) the gravitational, elastic, and rotational “fin- gerprint” effects of ice and ocean mass redistribution. Though the research communities working on these different effects each have a long history, the integration of all these different processes into interpretations of past changes and projections of future change is an active area of research. Fully character- izing the past contributions of these processes requires information from sources covering a range of timescales, including geological proxies, tide-gauge observations from the last ~3 centuries, and satellite-altimetry data from the last ~2 decades. Local sea-level rise projections must account for the different spatial patterns of different processes, as well as potential correlations between different drivers.Peer reviewe
The distortionary effects of tariff exemptions in Argentina
No full textTariff exemptions for exporters are widely used by many countries as aninstrument for providing export incentives. This author argues that when tariff exemptions are granted as a means of industrial regional promotion to an industry independently of its export performance, the tariff exemptions lose their potential as an export promotion instrument. The case of Argentina is of interest because it exemplifies the practice of many developing countries. A simple model is used to show that the indiscriminate use of duty exemptions has several undesirable effects : 1) duty exemptions deprive the government of revenues; 2) the more widespread the exemption, the less effective they become as an instrument for export promotion; 3) exemptions widen the variability of effective protection rates of industries in relation to their capital intensity; and 4) exemptions increase the demand for imports more than an export subsidy does, because output in the competing input industry contracts.Environmental Economics&Policies,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Economic Theory&Research,Consumption,Export Competitiveness

Reconciling Past Changes in Earth Rotation with 20th Century Global Sea-Level Rise: Resolving Munk’s Enigma
No full textIn 2002, W. H. Munk defined an important enigma of 20th century global mean sea-level (GMSL) rise that has yet to be resolved. First, he listed three canonical observations related to Earth rotation – (1) the slowing of the Earth’s rotation rate over the last three millennia inferred from ancient eclipse observations, and changes in (2) the amplitude and (3) orientation of the Earth’s rotation vector over the last century estimated from geodetic and astronomic measurements – and argued that they could all be fit by a model of ongoing glacial isostatic adjustment (GIA) associated with the last ice age. Second, he demonstrated that prevailing estimates of the 20th century rate of GMSL rise (~1.5-2.0 mm/yr), after correction for the maximum signal from ocean thermal expansion, implied mass flux from ice sheets and glaciers at a level that would grossly misfit the residual, GIA-corrected observations of Earth rotation. We demonstrate that the combination of lower estimates of 20th century GMSL rise (up to 1990), improved modeling of the GIA process, and a correction of eclipse records for a signal due to angular momentum exchange between the fluid outer core and mantle reconciles all three Earth rotation observations. This resolution adds confidence to recent estimates of the individual contributions to 20th century sea-level change and to projections of GMSL rise to the end of the 21st century based upon them.Peer reviewe
