Time Series Properties of Crime Rate Changes: Comments Related to David Greenberg’s Paper

Crimes exist in every society. This paper presents the statistical analysis of crime committed Inmates in Benin City Prison in Edo State with a suitable model using a time series approach. The paper examines the extent of crime committed in the prison for a period of seven years between 1999 to 2005. The study showedsss that age has no influence on the type of crime committed and that religion has no influence on the crime rate. The presentation gives future forecast in the population of prisoners in the prison with available crime rate data.

Close Resemblance

Two documented associations, viz., a negative one between maternal age and externalizing behavior of the offspring and a positive one between externalizing behavior in childhood and the probability of later (juvenile) delinquency, lead to the prediction that cohort-changes in crime rate over the years are associated with the age of the mothers of these cohorts when the children were born. This prediction was tested by comparing U.S. crime figures between 1987 and 1997 with maternal age figures 17 years earlier (1970–1980). Both time series show a close resemblance. Although causality from two different time series cannot be asserted, the existence of such a relationship is made plausible. Two different hypotheses are presented about the possible nature of causality. Results may be of value for studies in crime epidemiology.

Purpose This paper aims to draw on extant literature to ascertain the relevance of remittance receipts in improving the level of crime control in Nigeria. Design/methodology/approach The study uses time series data spanning for a period of 1986–2017. It adopts dynamic ordinary least square (DOLS), vector auto regression impulse response function, variance decomposition and Toda and Yamamoto causality approach to analyse the data. Findings The following findings are established: DOLS shows that remittance receipt has negative and significant impact on crime rate in Nigeria. The impulse response function indicates that a positive shock to the remittance inflows reduces the level of crime in Nigeria. Moreover, a positive shock to the crime rate decreases the remittance. This implies that both variables respond to each other. Toda and Yamamoto causality approach shows that there is unidirectional causality moving from remittance inflow to criminal activities in Nigeria. These results persist after considering other institutional variables. These findings support the previous evidences on remittances-crime nexus and as well support the opportunity cost theory of crime. Originality/value Apart from being the first study in African region that evaluates the relevance of remittances in crime control, it also analyses the dynamics between crime rate and remittance receipts using time series econometrics which makes the study to be unique. The study shows that remittances can be used as part of toolkits for controlling criminal activities in Nigeria.

AbstractThe occurrence of LDE-type flares in the last three cycles has been investigated. The Fourier analysis spectrum was calculated for the time series of the LDE-type flare occurrence during the 20-th, the 21-st and the rising part of the 22-nd cycle. LDE-type flares (Long Duration Events in SXR) are associated with the interplanetary protons (SEP and STIP as well), energized coronal archs and radio type IV emission. Generally, in all the cycles considered, LDE-type flares mainly originated during a 6-year interval of the respective cycle (2 years before and 4 years after the sunspot cycle maximum). The following significant periodicities were found:• in the 20-th cycle: 1.4, 2.1, 2.9, 4.0, 10.7 and 54.2 of month,• in the 21-st cycle: 1.2, 1.6, 2.8, 4.9, 7.8 and 44.5 of month,• in the 22-nd cycle, till March 1992: 1.4, 1.8, 2.4, 7.2, 8.7, 11.8 and 29.1 of month,• in all interval (1969-1992):a)the longer periodicities: 232.1, 121.1 (the dominant at 10.1 of year), 80.7, 61.9 and 25.6 of month,b)the shorter periodicities: 4.7, 5.0, 6.8, 7.9, 9.1, 15.8 and 20.4 of month.Fourier analysis of the LDE-type flare index (FI) yields significant peaks at 2.3 - 2.9 months and 4.2 - 4.9 months. These short periodicities correspond remarkably in the all three last solar cycles. The larger periodicities are different in respective cycles.
