Car Ownership and Mode of Transport to Work in Ireland

Rapid economic and demographic change in Ireland over the last decade, with associated increases in car dependence and congestion, has focused policy on encouraging more sustainable forms of travel. In this context, knowledge of current travel patterns and their determinants is crucial. In this paper, we extend earlier Irish research to examine the joint decision of car ownership and mode of transport to work. We employ cross-section micro-data from the 2006 Census of Population to estimate discrete choice models of car ownership and commuting mode choice for four sub-samples of the Irish population, based on residential location. Empirical results suggest that travel and supply-side characteristics such as travel time, costs, work location and public transport availability, as well as demographic and socio-economic characteristics such as age and household composition have significant effects on these decisions.

The Determinants of Mode of Transport to Work in the Greater Dublin Area. ESRI WP268. December 2008

Rapid economic and demographic change in the Greater Dublin Area over the last decade, with associated increases in car dependence and congestion, has focused policy on encouraging more sustainable forms of travel. In this context, knowledge of current travel patterns and their determinants is crucial. Here we concentrate on travel for a specific journey purpose, namely the journey to work. We employ cross-section micro-data from the 2006 Census of Population to analyse the influence of travel and supply-side characteristics, as well as demographic and socio-economic characteristics on the choice of mode of transport to work in the Greater Dublin Area

DRINKING WATER QUALITY. ESRI Research Bulletin 2009/2/3

The water we drink should be safe. The cryptosporidiosis outbreak in Galway in 2007 reminded us that it sometimes is not. But bad water quality does not only cause acute health problems. It also causes chronic ailments, including cancer. Therefore, the drinking water quality is monitored by the City and County Councils, overseen by the Environmental Protection Agency (EPA). A recent paper by Tol et al., examines the quality of drinking water in Ireland over time

Climate Policy and Corporate Behaviour. ESRI WP329. November 2009

In this paper, we study the impact of energy taxes and the EU ETS on a large number of firms in Europe between 1996 and 2007. Using company level micro-data, we examine how firms in different sectors were affected by environmental policies. Aspects of behaviour and performance studied include total factor productivity, employment levels, investment behaviour and profitability. On the whole, energy taxes increased total factor productivity and returns to capital but decreased employment, with a mixed effect on investment, for the sectors included in our analysis. However, large sectoral variation is observed, with some industries losing out in terms of productivity and profitability when faced with increased energy taxes, while others benefitted

Towards Regional Environmental Accounts for Ireland. ESRI WP293. April 2009

Existing environmental accounts for the Republic of Ireland are at the national level. This is fine for continental and global environmental problems, but information at a finer spatial scale is needed for local environmental problems. Furthermore, the impact of environmental policy may differ across space. We therefore construct regional estimates of the environmental pressures posed by Irish households and the environmental problems faced by them. The basic unit of analysis is the electoral district, and the prime data source is the CSO’s Small Area Statistics, a product of the Census. We use the results of classifying regressions of the Household Budget Survey to impute domestic energy use. We use engineering relations to impute transport fuel use, and secondary data on household behaviour to impute waste arisings. We use EPA data on drinking water use and quality per county. The results show marked regional differences. Electricity use and waste arisings are higher in the East and in the cities and towns. Transport fuel use is highest in the commuter belts around the cities and towns. Other energy is relatively uniform. There is no clear pattern in estimated drinking water use, which may be due to data quality. Drinking water quality is poor across much of the country, but different counties suffer from different problems. The regional estimates are constructed using data in the public domain. However, various government agencies hold data that would allow for the construction of more detailed, more accurate, and more extensive regional environmental accounts

The neutron and its role in cosmology and particle physics

Experiments with cold and ultracold neutrons have reached a level of precision such that problems far beyond the scale of the present Standard Model of particle physics become accessible to experimental investigation. Due to the close links between particle physics and cosmology, these studies also permit a deep look into the very first instances of our universe. First addressed in this article, both in theory and experiment, is the problem of baryogenesis ... The question how baryogenesis could have happened is open to experimental tests, and it turns out that this problem can be curbed by the very stringent limits on an electric dipole moment of the neutron, a quantity that also has deep implications for particle physics. Then we discuss the recent spectacular observation of neutron quantization in the earth's gravitational field and of resonance transitions between such gravitational energy states. These measurements, together with new evaluations of neutron scattering data, set new constraints on deviations from Newton's gravitational law at the picometer scale. Such deviations are predicted in modern theories with extra-dimensions that propose unification of the Planck scale with the scale of the Standard Model ... Another main topic is the weak-interaction parameters in various fields of physics and astrophysics that must all be derived from measured neutron decay data. Up to now, about 10 different neutron decay observables have been measured, much more than needed in the electroweak Standard Model. This allows various precise tests for new physics beyond the Standard Model, competing with or surpassing similar tests at high-energy. The review ends with a discussion of neutron and nuclear data required in the synthesis of the elements during the "first three minutes" and later on in stellar nucleosynthesis.Comment: 91 pages, 30 figures, accepted by Reviews of Modern Physic

The determinants of mode of transport to work in the Greater Dublin Area

Rapid economic and demographic change in the Greater Dublin Area over the period 1996-2006, with associated increases in car dependence and congestion, has focused policy on encouraging more sustainable forms of travel. In this context, knowledge of current travel patterns and their determinants is crucial. Here we concentrate on travel for a specific journey purpose, namely the journey to work. Using data on the full population of working individuals from the 2006 Census of Population, we analyse the influence of travel and supply-side characteristics, as well as demographic and socio-economic characteristics on the choice of mode of transport to work in the Greater Dublin Area. The results indicate that household composition, public transport availability, journey time and work location are particularly significant in explaining the choice of mode of transport to work.Modal choice Conditional logit Greater Dublin Area
