Overview• What are the long-term effects of injury on
well-being?– Adaptation to change (lottery wins, crime
states)• Measuring & Predicting Fear of Crime
– “How safe do you feel walking in your neighbourhood at night?”
• The Cost of Fear– Cost effectiveness of interventions
• Fear and Weapon Carrying– Does fear motivate harm avoidance through
self-defence
3
Well-being• British Cohort Study• Began in 1970
– data were collected about the births and families of babies born in the UK in one particular week (n = 17,415). All but one National Health Service hospital in the UK took part
– age 34 years data contains seriousness of injury (hospitalisation) and time since injury
• H: What are the long-term effects of injury on well-being?
4
Results• Ordered logistic regression (SEs adjusted for 11
clusters in government office region)– N = 1,512
• More life satisfaction:– Income (log income, β = 0.14, z = 2.03)
• Less life satisfaction– Victim of vandalism (β = -0.33, z = -2.20)– Poor health (β = -0.38, z = -3.30)
• Second order polynomial of time since accident– Satisfaction = -0.34(time) + 0.013(time²)

Implications• The long-term negative effects of serious injury on
well-being reduce as time passes• Is the same true for the effects of crime on well-
being?• Essential to know in the case of understanding the intangible costs of crime
• British Crime Survey includes good data on the nature of victimisation but, critically, lacks temporal element
• Paul Dolan, Joanna Shapland, Aki Tsuchiya, Chris Cox– Bespoke survey to consider long-term intangible costs
of crime– Access existing BCS respondents
7
Fear• Fear is a powerful motivator of behaviour
(discussed more later)• Are women more fearful of crime than men?• Vulnerability hypothesis – that women are more
vulnerable (through less physical strength compared to men)
• But not all crimes involve physical strength– H1: the dimensions of fear– H2: gender and fear– H3: explore other predictors
8
• 2001/2 and 2002/3 British Crime Survey• crime-specific ‘worry about’ questions and one
global “how safe do you feel walking in your neighbourhood at night?” question.
• For both sets of questions respondents’ choose one of four options for each question ranging from “very worried” to “not very worried at all”

Being female predicts Fear of Personal Harm, no gender differences on Fear of LossGraffiti predicts both fear types
12
• The ubiquitous FOC question “how safe do you feel walking in your neighbourhood at night?” most associated with fear of physical harm– Women more fearful of personal harm but no gender
difference for fear of personal loss– Vulnerability only half the story
• Gender difference in FOC research due to inappropriate FOC instrument
• Rubbish, graffiti & litter all increase FOC– Cost effective intervention to reduce FOC?
• Past victimisation increases FOC– But do people adapt?
13
Cost of Fear• Cost-effectiveness of interventions to reduce
FOC require knowledge on the value of FOC• Attempt to “shadow price” FOC• European Social Survey:
– Happiness– FOC– Income– Control variables
14
• Shadow pricing:– Income ↑ Happiness ↑– FOC ↑ Happiness ↓– What is the compensating differential in income for
the transition from no FOC to FOC?
• u is a measure of happiness, A is a constant, Y is a measure of income, Si are dummy variables for factors associated with happiness (i.e., FOC) and the X vector includes other variables that are known to influence happiness (e.g., age), ε is an error term that subsumes individual variation
15
• Happiness ≈ 0.587(log income) - 0.223(FOC*)– *binary variable denoting ‘no fear’ and ‘some’ or ‘more
fear’• Shadow price of FOC = €13,538• Since replicated by Mark Cohen (“The Effect of
Crime on Life Satisfaction”) who found the value of FOC to be $34,322
Predictors of weapon carrying & weapon victimisation
• Violent offenders report “self-defence” as primary motivation for weapon carrying (Brennan, 2007)
• BCS: “How often do you carry a weapon for protection?”– Reduced to binary variable– Small change in wording over years
• 2002/3-2007/8 BCS data sets combined – Waves combined to overcome rarity of weapon data– n=17,959 subset asked about weapons
Predictors of weapon carrying & weapon victimisation
• H1: Weapon carrying influenced factors related to self defence– previous victimisation– fear of harm– lack of confidence in CJS (state protection)

• Findings support “fear” hypothesis. – This may be linked to criminal lifestyle (Du Rant, 2004), but BCS
lacks offending-related items– Possible to combine BCS with offence data?
• Weapon carrying influenced as much by fear of, and previous, victimisation as demographics
• Women more fearful of personal harm, more likely to carry a weapon?
• Despite recent suggestions of rises in weapon carrying, likelihood decreased in recent years
• Panel survey to determine causality more effectively?• Offending & victimisation overlap
– What predicts being a victim of weapon crime…
Predictors of weapon victimisation
• For all forms of contact victimisation (burglary, violence, robbery, etc.) - “Did the person have a weapon?” – related to any type of crime
• 2002/3-2007/8 data sets (any victims: n=27,681)
• Hospital admissions increasing for weapon violence (Maxwell et al., 2007)
• H1: Weapon victims deprived, young males

Observations 27,655
ROC 0.65
Clustered by police force area
• As with most violence, males more likely• Repeat victimisations, threats and victimisation
away from neighbourhood increase risk– Territory/gangs?
• Surprisingly little effect of age– Different crimes over the lifespan?
• Young deprived men: reactive violence• Older: instrumental/coercive violence
• ‘Knife crime’ is not helpful as a catchall term– Should focus on the crime not the weapon, e.g.
Predictors of burglary more coherent than predictors of knife crime
23
Summary• Fear is an important facet of life
– substantial deleterious effects on well-being– Motivates avoidance/self-preservation behaviour
• Estimated cost of fear, in terms of annual household income are high suggesting interventions (removing graffiti) could be cost-effective
• FOC might be adaptive (get used to fear or return to baseline following victimisation) suggesting an important temporal element in understanding the intangible costs of crime
24
• The relationship between fear and serious violence is frequently overlooked. The BCS, in combination with more experimental work with weapon carriers offers the opportunity to monitor and better understand this relationship
• What drives fear may also drive weapon carrying– Media?– Subcultures of violence (if everyone thinks everyone
else is carrying a weapon then better off carrying a weapon)
– If clearing up graffiti reduces FoC would it also reduce weapon carrying?
