Background: Switzerland is a high-income country with low rates of fatal and nonfatal violence. Possibly due to these low prevalence rates, the costs of violence to Swiss society have received relatively little attention. Objective: This report aims to establish the prevalence rates of homicide and assaults (both physical and sexual) in Switzerland and assess their related tangible and intangible costs. Furthermore, it aims to estimate the economic cost of violence in Switzerland while specifically delving into the economic impact of domestic violence and intimate partner violence (IPV). Methods: We employ a comprehensive approach to categorize violence-related costs into three categories: (1) tangible direct costs; (2) tangible indirect costs; and (3) intangible costs. Within each category, we further classify costs based on the outcome of injuries, distinguishing between fatal and nonfatal violence. To estimate these costs, we use official crime data from the Federal Statistical Office for homicide and assaults. Recognizing the issue of underreporting in physical and sexual assault offenses, victimization surveys are employed to estimate the number of unreported cases. In the absence of Swiss data on the cost of injuries, the Centers for Disease Control and Prevention (CDC) provides estimates on medical costs, work loss costs, and the value of a statistical life (VSL)/quality of life loss costs. To ensure comparability, violence types are mapped, and costs are adjusted for purchasing power parity between the US and Switzerland. We also make adjustments to reflect the relative size of medical spending between the two countries. For comparison, we use prevalence rates of physical assault from Gallup. Using the same methodology, we also estimate the costs of domestic violence and IPV. Results: Our estimates suggest that the economic cost of violence in Switzerland is about USD 66.3 billion, equivalent to 8.3 percent of the country’s GDP, according to Swiss data. However, the costs could be as high as USD 73.4 billion, representing 9.2 percent of GDP, based on the Gallup World Poll data. Further, domestic violence alone accounts for at least 4.4 percent of Swiss GDP, while IPV accounts for at least 3.2 percent. Conclusions: Despite low Swiss prevalence rates of violence, the estimated costs of said violence are high. However, there is considerable uncertainty regarding our estimates due to missing Swiss data on medical and criminal justice costs, as well as the severity of injuries due to assault.

Violent crime and insecurity remain major barriers to prosperity in Latin America and the Caribbean (LAC). With just 8 percent of the global population, LAC accounts for a third of the world’s homicides. Building on the existing literature, this paper aims to support economic policymakers and development partners by exploring the interplay between insecurity and macroeconomic outcomes, with emphasis on the relationship between violent crime and growth, the business climate, and public finances. The analysis shows that national-level crime indicators mask huge internal disparities, and that municipalities with 10 percent higher homicide rates have lower economic activity by around 4 percent. The paper develops an innovative measure of insecurity—the share of crime-related news—and shows its association with lower industrial production. Using firm-level data, it also estimates that the direct costs of crime, for firms, are around 7 percent of annual sales, and these are much higher when gangs and drug-trafficking organizations are present. Violent crime rises with macroeconomic instability, inequality, and governance problems. Using a large cross-country panel, the analysis finds that homicides increase when a country is affected by negative growth, high inflation, or a worsening of inequality. Victimization surveys indicate that where populations are concerned with the rule of law—impunity and police corruption—only one in five victims file their case with the police. Lack of trust and crime can be mutually reinforcing. Finally, the paper documents the fiscal burden of security provision and finds that spending tends to be inelastic to crime and that spending efficiency could be improved. The paper concludes with policy lessons and areas for additional collaboration between national authorities, international partners, and key stakeholders. These focus on data collection and analysis, economic policies that may address the root causes and manifestations of crime, strengthening rule of law institutions, and intensifying regional exchanges on security and public finance issues.

Among all types of corruption, police corruption is probably the one that most directly hurts society, as those trusted with protecting the people either side with the criminals that victimize the citizens, or are themselves, criminals. However, both corruption and its effects are very difficult to measure quantitatively other than by perception surveys, but the perception that citizens have of this phenomenon may be different from reality. Using a simple agent-based model, we analyze the effect on crime rates as a result of both corruption and the perception of corruption within law-enforcement corporations. Our results show a phase transition in which crime can propagate across the population even when the majority of police officers are honest. We find that one of the parameters that strongly controls crime incidence is the probability that regular citizens become criminals. In contrast, other actions, such as arresting crime lords, or the amount of crime-associated money that is confiscated, have little impact on the long-term crime incidence. Our results suggest that in addition to combating corruption within law-enforcement institutions, to further reduce the incidence of crime, policymakers should strive to restore confidence in these institutions and the justice system.

The South African per-capita murder rate has steadily escalated since 2011/12, when it was at its lowest since 1994. The 2022/23 rate of 45 per 100 000 is the highest in 20 years. But focusing on national murder trends is misleading as trends vary greatly across the nine provinces. The current high per-capita murder rate is driven by high rates in the Eastern Cape, KwaZulu-Natal, the Western Cape and Gauteng. Key findings: South African murder trends vary considerably across provinces. The Eastern Cape, KwaZulu-Natal, the Western Cape and Gauteng have the highest per-capita murder rates. In 2022/23, the Eastern Cape had the highest murder rate (71 per 100 000), followed by KwaZulu-Natal and the Western Cape, both with annual murder rates of 56. The four provinces with the most murders have also recorded the highest per-capita murder rate increases in the last 10 years. Since 2011/12, rates have increased most dramatically in KwaZulu-Natal and the Eastern Cape. The increase has been greatest from 2017/18 to 2022/23. The per-capita murder rate in the Western Cape decreased over the last five years. Recommendations The government and society must prioritise reducing murder rates, which are high and increasing. The collection of data about murder, and the analysis thereof, must be improved. ‘One-size-fits-all’ approaches to addressing murder are unlikely to be effective. Responses should be adapted to respond to the drivers of murder focusing on high-murder localities. Priority should be given to understanding and addressing murder in the four provinces with the highest per-capita murder rates. KwaZulu-Natal and, to a lesser degree, Gauteng experienced major surges in murder in 2021/22, with increases continuing in 2022/23. These have taken them well above their rates in the year before the COVID-19 pandemic and national lockdown. Deaths during the July 2021 unrest were not a major contributor to the increases in murder in KwaZulu-Natal and Gauteng in 2021/22. Many experts believe that the entrenchment and growth of organised crime has played a major role in the increasing number of murders. More in-depth provincially focused research and analysis is required to better understand the factors and circumstances driving murder trends.

In 2005, the Swedish Crime Prevention Agency published a report about the link between immigration and crime. Since then, no comprehensive study has been conducted even though Sweden has experienced a large influx of migrants in combination with a rising crime rate. This study conducted by Göran Adamson and Tino Sanandaji is the first purely descriptive scientific investigation on the matter in fifteen years. The investigation (from 2002 to 2017) covers seven distinct categories of crime, and distinguishes between seven regions of origin. Based on 33 percent of the population (2017), 58 percent of those suspect for total crime on reasonable grounds are migrants. Regarding murder, manslaughter and attempted murder, the figures are 73 per cent, while the proportion of robbery is 70 percent. Non-registered migrants are linked to about 13 percent of total crime. Given the fact that this group is small, crime propensity among non-registered migrants is significant.
