Abstract
Objectives
This study evaluates the effects of precaution technologies (i.e., window bars, extra locks, alarms and electric fences, CCTV, private security, dogs and combinations of these tools) on household burglary and robbery in Brazil.
Methods
Using a sample of 121,042 unique households from the Brazilian National Household Sample Survey for 2009, this study estimates a Recursive Bivariate Probit to obtain the average treatment effect of these precaution technologies in the likelihood of home burglary and robbery victimization.
Results
This study demonstrates that technology does not reduce home burglaries, but certain combinations of technologies may reduce home robberies. The combination of electric fences and alarms with private security reduces the likelihood of home robbery by 9.5 %, and when combined with a dog, these technologies reduce the likelihood of home robbery by 86 %.
Conclusions
No precaution technology is able to prevent crimes when employed independently. Occupancy combined with a set of technologies can reduce the expected victimization in crimes against property.

This contribution from Cohen and Felson (1979) is known as the Routine Activities Theory.
Taking such possessions is the main motivation encountered by Rengert and Wasilchick (2000) in interviews with residence thieves.
For information about the effect of the justice system in deterring crime, see Eide (1994).
From the social perspective, observable technologies may or may not improve social welfare. At first glance they have no effect when only displacement effects are considered. However, the more individuals who adopt these technologies, the lower the probability will be that a potential criminal can successfully commit a crime. The increase in expected costs from criminal activity leads to a reduction of criminals, which can improve social welfare (Shavell 1991; Ayres and Levitt 1998).
See Wooldrige (2010) chapter 15.7.3 for further details.
In this case, obtaining the necessary counterfactual analysis to assess the effect of the treatment is possible.
The percentage of residential victims of burglary and robbery using precaution technology are reported in Table 9 of the appendix.
In many cases people have dogs as pets and consider them a precaution technology, but the dogs may not necessarily serve security purposes.
Only information from the person responsible for the residence is taken into account, which prevents counting instances of victimization multiple times. People between 16 and 100 years old are considered responsible for the residence. The sample includes 121,042 households.
The PNAD questionnaire does not require the identification of family members. It is not possible to identify the family to which each individual belongs. The only information available about family composition is the number of components and the number of children under ten years of age living in the residence.
The active participation of potential victims in the task of avoiding potential crimes is what Cornish and Clarke (1986) call the “situational control of crime”.
All the models include controls for household and residence characteristics and Brazilian states to capture non observed regional characteristics regarding crime.
A likelihood ratio (LR) test with the null hypothesis ρ = 0, where ρ is the coefficient of correlation between the residuals of the discrete bivariate model as indicated in Eq. (5). Monfardini and Radice (2008) shows that LR exogeneity test outperform other tests, such as Lagrange multiplier (LM) and conditional moment (CM), in the recursive bivariate probit context.
Differently from the univariate case (i.e. Probit), which evolves only a standard normal distribution, the bivariate case evolves two bivariate conditional distributions that generates different probabilities which may be greater, equal or smaller than the other, consequently, the same sign for RBP coefficients and ATE is not guaranteed.
Such an alarm system may be connected to a telephone line.
Previous studies demonstrate that the high frequency of false alarms tends to decrease alarms’ effectiveness (Cook and MacDonald 2011).
A private security service can take many forms, including the permanent presence of a guard or porter, alarm response services, and night watch services, among other more sophisticated forms, such as a team of armed guards.
Dogs have a higher capacity to hear and smell than human beings.
The PNAD data indicate that 42.87 % of apartment buildings in Brazil had some type of private security in 2009, whereas the same type of service was present in only 8.07 % of other types of residences.
The appendix also presents the marginal effects of the variable that controls for the Brazilian States.
The information contained in the PNAD 2009 indicates that mobile phones are taken by the criminals in 32.19 % of robberies and 14.74 % of burglaries.
It is increasingly common to observe gangs specialized in burglarizing and robbing residences. There is a gain in the division of labor, which includes the tasks of monitoring, performance and escape, as well as in the need of a fence for the stolen objects.
