A Pitfall in Using Troll TSLS with Linear Restrictions in TROLL
Conniffe, Denis; FitzGerald, John; Hughes, Gerard (ESRI, Dublin, 1985) 
Alcohol Use in Ireland: Some Economic and Social Implications
Conniffe, Denis; McCoy, Daniel (ESRI, Dublin, 1993) 
Approximating the distribution of the R/s statistic
Conniffe, Denis; Spencer, John E. (Economic & Social Studies, Dublin, 2000)The R/s statistic, used for many years in hydrology, is increasingly employed in economics, although deficiencies in knowledge about its exact distribution have inhibited progress. Harrison and Treacy (1997) described some ... 
Does the stochastic specification of the linear expenditure system matter?
Conniffe, Denis; Eakins, John (Economic & Social Studies, Dublin, 2003)When ?income? in a system of demand equations is defined as total expenditure, actual expenditure on any commodity must lie between zero and income, or equivalently, budget shares must lie between zero and one. But models ... 
Energy Elasticities: Responsiveness of Demands for Fuels to Income and Price Changes
Conniffe, Denis; Scott, Sue (ESRI, Dublin, 1990) 
Equivalence Scales and Costs of Children
Conniffe, Denis; Keogh, G (ESRI, Dublin, 1988) 
Estimating equations with information loss on at least one dependent variable
Conniffe, Denis (Economic & Social Studies, Dublin, 1995)Efficient, or joint, estimation of a pair of linear equations with the same explanatory variables reduces to separate estimation of each equation. This is no longer the case if information has been lost on at least one ... 
Evaluating state programmes: ?natural experiments? and propensity scores
Conniffe, Denis; Gash, Vanessa; O'Connell, Philip J. (Economic & Social Studies, Dublin, 2000)Evaluations of programmes ? for example, labour market interventions such as employment schemes and training courses ? usually involve comparison of the performance of a treatment group (recipients of the programme) with ... 
Generalised means of simple utility functions with risk aversion
Conniffe, Denis (Economic & Social Studies, Dublin, 2008)The paper examines the properties of a generalised mean of simple utilities each displaying risk aversion, that is, with first derivative positive and second derivative negative. It shows the mean is itself a valid utility ... 
Household Energy Expenditures: Policy Relevant Information from the Household Budget Survey
Conniffe, Denis (ESRI, Dublin, 2000)This paper utilised the national Household Budget Survey to examine patterns in energy use and their relevance to policy. Income elasticities for the various fuels were calculated and their implications assessed, with ... 
Irish house price indices ? methodological issues
Conniffe, Denis; Duffy, David (Economic & Social Studies, Dublin, 1999)This paper reviews the international literature on house price indices, looking at the basic methodologies employed, the variables chosen for the indices and the functional forms used. Ideas are sought for future improvements ... 
Likelihood and Estimation
Conniffe, Denis (ESRI, Dublin, 1986) 
Logistic transformation of the budget share in Engel curves and demand functions
Conniffe, Denis (Economic & Social Studies, Dublin, 1993)Models relating the budget share of a commodity to (the logarithms) of income and prices are popular in the analysis of household budget survey data and of time series data on commodity expenditures. This paper shows that ... 
Models of Irish tobacco consumption
Conniffe, Denis (Economic & Social Studies, Dublin, 1995)This paper estimates several econometric models of tobacco consumption, employing Irish annual time series data. The approaches examined include the recently developed rational addiction model and a twocomponent model ... 
More about Geary and the "Taxi" problem
Conniffe, Denis; Geary, R. C. (Economic & Social Studies, Dublin, 1996)Geary's treatment of the "taxi" problem was recently reexamined by Spencer and Largey (1993). This paper investigates the topic further, partly to place Geary's estimator in the context of more general methods and also ... 
Obtaining Expected Maximum Log Likelihood Estimators
Conniffe, Denis (ESRI, Dublin, 1988) 
R.A. Fisher and the development of statistics  a view in his centerary year
Conniffe, Denis (Statistical and Social Inquiry Society of Ireland, 1991)It is certainly appropriate that The Statistical and Social Inquiry Society of Ireland should present a paper about the great statistician Fisher in this year, the centenary of his birth. I am very pleased to be giving ... 
Sums and products of indirect utility functions
Conniffe, Denis (Economic & Social Studies, Dublin, 2002)There are relatively few known demand systems that are theoretically satisfactory and practically implementable. This paper considers the possibility of deriving more complex demand systems from simpler known ones by ... 
Testing a model parameter when another is unidentified under the null
Conniffe, Denis (Economic & Social Studies, Dublin, 1998)Some standard test procedures, such as Score and Likelihood Ratio, replace nuisance parameters by their maximum likelihood estimates under the null hypothesis about the parameter of interest. In some models, however, a ... 
The Costs to Ireland of Greenhouse Gas Abatement
Conniffe, Denis; FitzGerald, John; Scott, Sue; Shortall, F (ESRI, Dublin, 1997)
