An econometric analysis of burglary in Ireland

Open Access publications (2004)

Kevin Denny Reamonn Lydon Colm Harmon

This paper outlines an econometric model of the level of burglary in Ireland between 1952 and 1998. We explain the evolution of the trend in Burglary in terms of demographic factors: in this case the share of young males in the population, the macro-economy in the form of consumer expenditure and two characteristics of the criminal justice system : the detection rate for these crimes and the size of the prison population. The share of young males is associated with higher levels of these crimes. Imprisonment and detection act as powerful forces for reducing crimes, the effects of aggregate consumption are more difficult to pin down but we show that higher spending is associated with more lucrative but probably fewer crimes. One somewhat surprising result is that we were unable to find any robust effect from direct measures of labour market activity such as unemployment rates or wage levels.

A Dynamic Model of Demand for Private Health Insurance in Ireland

SSRN Electronic Journal (2006)

Claire Finn Colm Harmon

The Irish health care system offers a tax financed, universal entitlement to public care at a nominal user fee, nonetheless 50% of the Irish population purchase private health insurance. This paper empirically models the propensity to insure as a function of individual and household characteristics using panel data analysis and compares three alternate approaches; a static, chamberlain-mundlak and dynamic specification. Using panel data from 1994 to 2000, we consider whether propensity to insure is in fact a function of heterogeneity or of state dependence. A range of individual and household characteristics is shown to influence propensity to insure. Overall the positive effect of education and income and the negative effect of poor health status remain robust across three specifications. In moving toward a dynamic specification, we show that persistence is a highly significant determinant of demand for private health insurance and also that it reduces the size of the coefficients on the regressors. The latter point highlights that while education, income and, to a lesser extent, health status have very large effects on probability of insuring, these effects are overestimated where no attempt is made to control for unobserved heterogeneity or state dependence.

Experimental Tests of Survey Responses to Expenditure Questions

SSRN Electronic Journal (2009)

David Comerford Liam Delaney Colm Harmon

This paper tests for a number of survey effects in the elicitation of expenditure items. In particular we examine the extent to which individuals use features of the expenditure question to construct their answers. We test whether respondents interpret question wording as researchers intend and examine the extent to which prompts, clarifications and seemingly arbitrary features of survey design influence expenditure reports. We find that over one quarter of respondents have difficulty distinguishing between "you" and "your household" when making expenditure reports; that respondents report higher pro-rata expenditure when asked to give responses on a weekly as opposed to monthly or annual time scale; that respondents give higher estimates when using a scale with a higher mid-point; and that respondents report higher aggregated expenditure when categories are presented in a disaggregated form. In summary, expenditure reports are constructed using convenient rules of thumb and available information, which will depend on the characteristics of the respondent, the expenditure domain and features of the survey question. It is crucial to further account for these features in ongoing surveys.

Enhancing the comparability of self-rated skills-matching using anchoring vignettes

RePEc: Research Papers in Economics (2009)

Martin Ryan Liam Delaney Colm Harmon

This research is concerned with the skills-match between researchers' Ph.D. training and their subsequent university employment. Self-rated skills-matching is considered in light of the anchoring vignettes technique. This technique is used to adress comparability issues in survey research. It has been documented that individuals with more education and skills have the highest expectations for their jobs and careers; and are more easily disappointed. This is one reason why there may be comparability problems in self-rated skills matching. Only a few studies (at least one using objective data, a few more using self- reported data) have examined the issue of skills-matching. Furthermore, the results from objective data are somewhat problematic. This underscores the need to apply anchoring vignettes to self-reported data. Mismatch is associated with substantially lower earnings; with more comparable measures, wage penalties can be more accurately estimated.

Naturalistic monitoring of the affect-heart rate relationship: A day reconstruction study.

Health Psychology (2010)

Michael Daly Liam Delaney Peter Doran Colm Harmon Malcolm MacLachlan

Prospective studies have linked negative affect with hypertension, cardiovascular disease, and mortality. This study aims to identify if cardiovascular activity in day-to-day settings is related to affect levels as assessed using the Day Reconstruction Method (Kahneman, Krueger, Schkade, Schwarz, & Stone, 2004).186 people underwent baseline physiological testing and were monitored naturalistically for an entire day. Multilevel models were the principal analyses used.We utilized an online day reconstruction survey to produce a continuous account of affect, social interactions, and activity patterns during waking hours. Ambulatory heart rate (HR) was assessed during the same period. Personality, health behavior, consumption, self-reported activity, and baseline physiological characteristics were assessed to isolate the relationships between affect and HR.Negative affect predicted an elevated ambulatory HR and tiredness predicted a lower HR. Associations between negative affectivity and increased cardiovascular reactivity were maintained after taking account of baseline physiological factors, health behavior, and personality.Negative affect in everyday life is a reliable predictor of HR. Combining day reconstruction with psychophysiological and environmental monitoring is a minimally invasive method with promising interdisciplinary relevance.
