Vibrational coherence in electron spin resonance in nanoscale oscillators

We study a scheme for electrical detection, using electron spin resonance, of coherent vibrations in a molecular single electron level trapped near a conduction channel. Both equilibrium spin-currents and non-equilibrium spin- and charge currents are investigated. Inelastic side-band anti-resonances corresponding to the vibrational modes appear in the electron spin resonance spectrum.Comment: 4 pages, 3 figures: Published versio

Econometric Macro-Model Building in the Irish Context. Quarterly Economic Commentary Special Article, June 1970

Building an econometric macro-mociel of any country involves a major commitment of resources--research and clerical manpower, and computer time. This is so because, if it is to. be useful, the model must reflect as accurately · as possible, and in some detail, the complex interaction of forces that generate the time path of the national economy. This can only be done-if it can be done at all-by a close union of detailed, expert opinion on the structure of each sector of the economy and ingenious, tedious experimentation in the econometric field A model of the national economy. is more than a collection of sector by sector studies because great care must be taken t<f specify the interaction of the sectors, but the link between the macro-model builders and the economists who have specialised in various facets of the economy (such as consumptionsavings behaviour, price formation etc.) must be · very close. Since it may not be unreasonable to spend over a year producing a worthwhile study of one aspect of the national economy, · obviously the time to be allocated for producing a useful macro-model must be measured in years. Klein puts it as follows : To build a realistic model of the American economy requires a year in data collection and preparation, another year in estimation with much experimentation following both false and fruitful leads, and finally years more of testing the model, applying it to practical problems. Every two or three years the model must be revised to keep it up to date. The magnitude of the effort involved is a definite drawback of the approach. [7, p. 269]. Unfortunately, the effort required is in no way proportional to the size of the country

The Building Society Mortgage Market in Ireland. Quarterly Economic Commentary Special Article, September 1980

This paper sets out an econometric model of the Irish building society mortgage market. It arises out of work being carried out on the housing market in Ireland. There have been a number of international studies which have tried to model housing and mortgage markets (see Muth, 1960; Whitehead, 1974; Hadjimatheou, 1976; Artis, Kiernan and Whitney, 1975; Smith, 1969; Arcelus and Metzler, 1973 and Swan, 1973). For Ireland, Nolan (1979) attempted to model the housing market while Hewitt and Thom (1979) estimated a quarterly model of Irish building society behaviour over the period 1970-77

The Updating of Certain Econometric Models. Quarterly Economic Commentary, September 1970

The editors of the Quarterly Ec:onomic Commentary make use of a variety of econometric models, developed in the past by the Institute, as a guide to forecasting. Such models indicate the implications of different assumptions about the course of the economy, the impact on the economy of extrapolated trends, and the consistency of the forecasts of the National Accounts components made in Section 2.2, both with themselves and with the experience embodied in the models. Following normal practice in the use of working models, it was decided to re-run the equations using the latest figures, and where possible to attempt an improvement in the models. Updating the models not only keeps them relevant to current conditions, but also serves as a check on the stability over time of the implied relationships

ESRI Demand Responsiveness Enquiry. ESRI Memorandum Series No. 115 1975

Irish manufacturing industry suffered a fall in its sales volume in 1975 over it's 1974 level. In an effort to clarify the relative importance of price competitiveness vis a vis other factors, the authors conducted a survey amongst firms in Irish manufacturing industry in December 1975. The results indicate what managers of firms perceived as the reasons for their poor sales performance. The questions put, of their very nature require subjective answer. Thus, managers, when faced with a leftward shift in their firms demand curve, were asked to distinguish the separate effects of a fall in consumer demand, and of any loss of price competitiveness. An effort was also made to assess the degree of price responsiveness of demand amongst sectors in both domestic and export markets. The normal caveats about this type of subjective enquiry of course apply. The survey covered those firms which participate in the monthly CII/ESRI Business Opinion Survey. Of a total of 320 questionnaires despatched, 218 usable replies were received, a response rate of just over 68%. For the purposes of the survey the firms were classified in accordance with the ten sector classification used by the CSO in the Quarterly Industrial Enquiry. The actual processing and calculation of the results was carried out by computer, each firm's replies being weighed by that firm's turnover weight as used in the CII/ESRI survey. Sectoral output weights were derived from the finer sectoral classification of the same survey

Government Borrowing, Bank Liquidity and Interest Rates. Quarterly Economic Commentary Special Article, September 1980

Ireland's participation in the EMS, the introduction of exchange controls, and the break in the traditional parity between the Irish pound and sterling brought about a totally new environment in which changes in domestic bank liquidity came to play an important role in determining the level of Irish interest rates. This paper looks at the main influences on bank liquidity and examines the sources of changes in it over recent years since 1975, with particular reference to 1979 and 1980. The purpose is to highlight the relationships between bank liquidity and the Government Borrowing Requirement and show how the manner in which the Government finances its deficit can affect the level of interest rates. The size of the annual Government deficit has now grown to such large proportions that the manner in which it is financed has become an important policy issue. By illustrating the effects on interbank rates and gilt yields it is hoped that the paper will contribute to the debate about whether the deficit should be financed by monetary or non-monetary means and whether the Government should borrow abroad or from the Central Bank

An Econometric Model of Non-Agricultural Stock Changes. Quarterly Economic Commentary Special Article, December 1977

Macroeconometric models pay particular attention to the equations dealing with the major components of aggregate demand, such as consumption, investment and exports. In the Central Bank's econometric model [l], investment is broken down into three components: residential investment, non-residential investment and stockbuilding. While stockbuilding is a relatively small proportion of aggregate demand, it is a volatile magnitude and has traditionally been accorded an important place in the study of economic fluctuations. This note is devoted to a discussion of the stockbuilding equation. The following sections deal with the models tested, the empirical results and the conclusions. Data, sources and methods are given in the appendix

Competitiveness Indices for Irish Manufactured Exports. Quarterly Economic Commentary Special Article, July 1981

This paper is devoted primarily to the construction of competitiveness indices for Irish manufactured exports. Our principal motivation in conducting such an exercise is the fact that no satisf a,ctory measures of competitiveness have as yet been developed for Ireland despite which the concept of competitiveness, and the problems assoicated with declining competitiveness in particular, frequently figure in public discussions of Ireland's economic performance. This concern is exemplified, for instance, by the fact that it is a recurring theme in the Quarterly Bulletins and Annual Reports of the Central Bank

Sectoral Changes in the Labour Force over the Period 1961-1980 with Particular Reference to Public Sector and Services Employment. Special Article in Quarterly Economic Commentary, Winter 2015

A knowledge of the significant changes which have been taking place in the sectoral composition of employment is fundamental to a proper understanding of the recent evolution of the labour force. This paper traces the changes in the numbers at work in broad sectors of the Irish economy over the period 1961-80. The basic information is given in Appendix I, Table A which contains an annual sectoral subdivision under four broad headings (Agriculture, Manufacturing, Building and Services); Tables 1 and lA following show these data for selected years* in this period with a somewhat more detailed sectoral subdivision, the second table giving absolute and relative employment changes by sector for the 1961/1971 and 1971/1979 periods
