AbstractCrime rates per capita are used virtually everywhere to rank and compare cities. However, their usage relies on a strong linear assumption that crime increases at the same pace as the number of people in a region. In this paper, we demonstrate that using per capita rates to rank cities can produce substantially different rankings from rankings adjusted for population size. We analyze the population–crime relationship in cities across 12 countries and assess the impact of per capita measurements on crime analyses, depending on the type of offense. In most countries, we find that theft increases superlinearly with population size, whereas burglary increases linearly. Our results reveal that per capita rankings can differ from population-adjusted rankings such that they disagree in approximately half of the top 10 most dangerous cities in the data analyzed here. Hence, we advise caution when using crime rates per capita to rank cities and recommend evaluating the linear plausibility before doing so.

The Impact

PurposeThe aim of this paper is to quantify the impact of transboundary air pollutants, particularly those related to urban traffic, on health outcomes. The importance of focusing on the health implications of transboundary pollution is due to the fact that these emissions originate from another jurisdiction, thus constituting international negative externalities. Thus, by isolating and quantifying the impact of these transboundary air pollutants on domestic health outcomes, the authors can understand more clearly the extent of these externalities, identify their ramifications for health and emphasise the importance of cross-country cooperation in the fight against air pollution.Design/methodology/approachThe authors employ panel data regression analysis to look at the relationship between emissions of transboundary air pollution and mortality rates from various respiratory diseases among a sample of 40 European countries, over the period 2003–2014. In turn, the authors use annual data on transboundary emissions of sulphur oxides (SOx), nitrogen oxides (NOx) and fine particulate matter (PM2.5), together with detailed data on the per capita incidence of various respiratory diseases, including lung cancer, asthma and chronic obstructive pulmonary disease (COPD). The authors consider a number of different regression equation specifications and control for potential confounders like the quality of healthcare and economic prosperity within each country.FindingsThe results show that transboundary emissions of PM2.5 are positively and significantly related to mortality rates from asthma in our sample of countries. Quantitatively, a 10% increase in PM2.5 transboundary emissions per capita from neighbouring countries is associated with a 1.4% increase in the asthma mortality rate within the recipient country or roughly 200 deaths by asthma per year across our sample.Originality/valueThese findings have important policy implications for cross-country cooperation and regulation in the field of pollution abatement and control, particularly since all the countries under consideration form a part of the UN's Convention on Long-Range Transboundary Air Pollution (CLRTAP), a transnational cooperative agreement aimed at curtailing such pollutants on an international level.

The Impact

Carbon dioxide (CO2) emission derived from economic activities results primarily from the fossil fuels consumed. The variety of fossil fuels used, the degree of efficient consumption of energy, economic growth and national population size determine the total amount of CO2 emission in a country. Considering its population size as well as its potential for economic development, China is expected to play a key role in the global warming issue in concert with other industrialized Asian countries, including Japan. In the present study, the impact of population increase on total CO2 emission in China during the period 1982-1990 was analyzed. During the study period, population increase and CO2 emission per capita were 21 per cent and 70 per cent, respectively. In terms of population increase by region, some provinces in the inland areas and megacities, like Shanghai and Beijing, contributed the highest figures. To cope with high fertility in the inland areas as well as massive population inflow into the urban areas simultaneously, increasing the number of medium-sized cities to be located in the inland areas could be a solution. For CO2 emission per capita, the figures for the North-Eastcrn provinces and South-Eastern provinces along the coast are remarkable. The estimate of total emission of CO2 by 2010 is 1.6 million tons, a 74 per cent increase from 1992. Energy transition is the key to the stabilization of CO2 emission in China.

Purpose The purpose of this paper is to examine the impact of the mandatory adoption of eXtensible Business Reporting Language (XBRL) on firm’s stock liquidity. Design/methodology/approach Using a random-effects model, this study examines the impact of the mandatory adoption of XBRL (ADOPXBRL) on firm’s stock liquidity of 980 companies pertaining to 13 countries for a period from 2000 to 2016. Findings This paper finds that the mandatory ADOPXBRL affects negatively and significatively Amihud’s (2002) illiquidity ratio. Therefore, mandatory XBRL adoption enhances the firm’s stock liquidity. In addition, this paper finds that the impact of the mandatory ADOPXBRL on firm’s stock liquidity is more pronounced in civil law countries than in common law countries. Originality/value This paper contributes to the literature on the advantage of XBRL especially for the civil law countries by examining the impact of the mandatory ADOPXBRL on firm’s stock liquidity.

Determining Factor

The aim of this paper is to explore the relationship between intelligence and economic and financial crimes. For this purpose, we use a cross-sectional sample of 182 countries for the time span of 2012–2017. Our research provides empirical evidence on the existence of a significant impact of intelligence upon economic and financial crimes. When we analyze the entire sample, we find that intelligent people are more prone to comply with the law and thus increase the efficiency of implementing government policies to reduce economic and financial crimes. However, when we conduct our analysis among the two subgroups of high- and low-income countries, different results are obtained. For high-income countries, we obtain evidence of a positive coefficient for the impact of intelligence on economic and financial crimes, meaning that increased intellectual capacities of people from these countries, including high professional knowledge and skills, are used to break the traditional technology in order to get illegal benefits. Our results conducted for the low-income countries' subsample do not support intelligence as being a determining factor for economic and financial crimes; in these countries, other determinants are more important for engaging in such activities. Our study may have important implications for the policymakers who must acknowledge that various policies in the field of economic and financial crimes need to be differentially adopted depending on the level of development of each country, which offers different ways of involvement in such crimes, related to the level of people's intelligence.
