Recession and recovery from the pandemic
No full textWe develop an SIR-macroeconomic model with virus detection and inequality to study their implications for economic and health consequences during a pandemic crisis. We find a two-way relationship between the pandemic recession and inequality that exacerbate each other although such a vicious circle could be broken by accurate and extensive testing. This mitigation effect can be improved given complementary arrangements such as social protection. The extensive virus detection could not only be a better alternative intervention to lock-down to break the “life-or-economy” trade-off, but also prevent the economy to be permanently damaged if there is reinfection

No full textMeasuring energy efficiency and its contribution towards meeting CO2 targets: estimates for 29 OECD countries
No full textUsing results for 29 OECD countries from the estimation of an extended version of the model advocated by Filippini and Hunt (2011a), actual energy consumption and CO2 emissions are compared to notional energy consumption and CO2 emissions if the countries were energy efficient. This shows the contribution that improvements in energy efficiency can make towards the reduction in CO2 emissions. It is found that in many countries efficiency improvements alone are not likely to be sufficient to bring about reductions in CO2 emissions required to meet ambitious obligations. However, this is not the case across all countries included in the investigation. Moreover, it is shown that some of the world’s largest OECD emitters can make a significant contribution to CO2 reductions from becoming energy efficient. Therefore the negotiations of the new legally binding treaty agreed under the Durban Platform should promote emission reduction targets that incentivise national energy efficiency.emissions, energy efficiency, Durban Platform.

Estimating Underlying Energy Demand Trends using UK Annual Data
No full textEmploying the Structural Time Series Model (STSM) approach suggested by Harvey (1989, 1997), and based on annual data for the UK from 1967-2002, this paper reiterates the importance of using a stochastic rather than a linear deterministic trend formulation when estimating energy demand models, a practice originally established by Hunt et al. (2003a,b) using quarterly UK data. The findings confirm that important non-linear and stochastic trends are present as a result of technical change and other exogenous factors driving demand, and that a failure to account for these trends will lead to biased estimates of the long-run price and income elasticities. The study also establishes that, provided these effects are allowed for, the estimated long-run elasticities are robust to the different data frequencies used in the modelling.Energy Demand, Underlying Trends.
Mechanics of inhomogeneous turbulence and interfacial layers
No full textThe mechanics of inhomogeneous turbulence in and adjacent to interfacial layers bounding turbulent and non-turbulent regions are analysed. Different mechanisms are identified according to the straining by the turbulent eddies in relation to the strength of the mean shear adjacent to, or across, the interfacial layer. How the turbulence is initiated and the topology of the region of turbulence are also significant factors. Specifically the cases of a layer of turbulence bounded on one, or two, sides by a uniform and/or shearing flow, and a circular region of a rotating turbulent vortex are considered and discussed.
The entrainment processes at fluctuating interfaces occur both at the outer edges of turbulent shear layers, with and without free-stream turbulence (e.g. jets, wakes and boundary layers), at internal boundaries such as those at the outside of the non-turbulent core of swirling flows (e.g. the ‘eye-wall’ of a hurricane) or at the top of the viscous sublayer and roughness elements in turbulent boundary layers. Conditionally sampled data enables these concepts to be tested. These concepts lead to physically based estimates for critical modelling parameters such as eddy viscosity near interfaces, entrainment rates, maximum velocity and displacement heights
The economics of energy efficiency
No full textAs an essential component for economic growth, energy has a significant impact on the global economy. The need to meet growing energy demand has prompted cutting-edge innovation in clean technology in an attempt to realise environmental and cost objectives, whilst ensuring the security of energy supply. This Handbook offers a comprehensive review of the economics of energy, including contributions from a distinguished array of international specialists. It provides a thorough discussion of the major research issues in this topical field of economics
An Analysis of UK Energy Demand Using Multivariate Cointegration
No full textIn this paper we estimate an aggregate energy demand equation by a maximum likelihood procedure proposed by Johansen (1988) for the UK using annual data from 1967 to 1994. The influence of the price of energy, income and temperature on energy consumption is examined. A unique long-run equilibrium relationship between energy demand, income and price is found to exist for the period, with temperature affecting demand only in the short-run. The resultant estimated elasticities are robust to different specifications and corroborates the findings of Hunt and Manning (1989) although a weaker long-run effect of income on energy demand was observed.

The Canadian harp seal hunt: observations on the effectiveness of procedures to avoid poor animal welfare outcomes
No full textThe Canadian harp seal (Pagophilus groenlandicus) hunt has, for several decades, raised public concerns related to animal welfare. The field conditions under which this hunt is carried out do not lend themselves easily to detailed observations and analyses of its killing practices. This article reports observations carried out over several seasons that aimed at obtaining more specific information about the conditions under which seals are killed, in order to assess potential welfare issues and explore avenues for possible improvements in its practice. A standardised three-step process for killing seals (ie stunning, checking by palpation of the skull, and bleeding) was recently implemented to maximise the proportion of animals that are killed rapidly with minimum pain. Based on field observations, the rifle and the hakapik, when used properly, appeared to be efficient tools for stunning and/or killing young harp seals. All carcases of seals observed to be killed with a rifle, either on the ice or in the water, could be recovered. However, shooting seals in water rather than on ice carried a higher risk of poor welfare outcome because of the limited opportunities to shoot the animals again if not stunned with the first shot. Based on current practices, there is no reliable evidence that the Canadian harp seal hunt differs from other forms of exploitation of wildlife resources from the perspective of animal welfare. Although opportunistic field observations may be less amenable to generalisation than structured studies, we believe that they reflect the reality of the hunt and provide valuable information to direct the evolution of its practice.P.-Y.
