COVID-19 and retail: The catalyst for e-commerce in Belgium?

Since the turn of the century especially small, local retailers struggle with the advent of e-commerce. It is hence no surprise that the retail sector is one of the hardest-hit sectors in the current pandemic. To understand the short- and longer-term impacts of COVID-19 on retail, we conducted two surveys to understand ongoing changes in the sector. By contrasting changing consumer behavior with the actions taken by local retailers, we assess whether the current pandemic is potentially a catalyst for e-commerce in Belgium. We do this based on a newly constructed framework of e-retail accessibility, as the differences between online and physical retail require a revision of the traditional economic geographical perspective on retail performance as introduced by Christaller (1933). We conclude that the COVID-19 pandemic holds ample opportunities for an increase in the three components of e-retail accessibility, but that a lack of professionalism might prevent traditional local retailers to retain a share of the expanded online market. This could well mean the final blow for local brick and mortar shops if, as is predicted, the share of online shopping in total retail expenditure remains high after the pandemic.     

Measuring and improving safety culture in organisations: an exploration of tools developed and used in Belgium

To support organisations in addressing their safety culture, practical tools have been developed worldwide. Based on such practical tools, it is possible to measure where an organisation is situated regarding its safety culture in order to identify priority areas, formulate appropriate improvement strategies and determine changes over time. In this paper, it is examined which practical tools to measure and improve safety culture are provided on the Belgian market. In total, 15 Belgian tools were identified, of which 8 agreed to cooperate. Amongst the included tools, there is a lot of variation regarding the methods to diagnose the safety culture and the overall procedure to improve the safety culture. The importance to adapt the tool to the specific needs and context of organisations is acknowledged in most of the tools, as well as the importance to use a multi-method approach to measure the safety culture. Also, it is recognised that all hierarchic levels should participate during the process of diagnosing the safety culture. A point of attention is this overall participation during the validation of the results of the diagnosis, and the priority setting of the recommendations, which is mainly done by the higher management. The development of the Belgian tools is based on experience with a focus on direct practical application, which leads to the fact that none of the tools are validated through scientific evidence. Another point of attention is that organisations pay too little attention at the continuity of safety culture research. And finally, the question can be raised if the safety culture tools actually address the concept ‘safety culture’, or if they address only a subset of the concept. When safety culture is addressed, a comprehensive approach should be used, where technological, organisational, human and external aspects are taken into account as interacting and interrelating elements.     

Geographic distribution of suicide and railway suicide in Belgium, 2008–2013: a principal component analysis

This study investigated the geographic distribution of suicide and railway suicide in Belgium over 2008--2013 on local (i.e., district or arrondissement) level. There were differences in the regional distribution of suicide and railway suicides in Belgium over the study period. Principal component analysis identified three groups of correlations among population variables and socio-economic indicators, such as population density, unemployment, and age group distribution, on two components that helped explaining the variance of railway suicide at a local (arrondissement) level. This information is of particular importance to prevent suicides in high-risk areas on the Belgian railway network.

Health economic evaluation of a vaccine for the prevention of herpes zoster (shingles) and post-herpetic neuralgia in adults in Belgium

Abstract

Objective:

To determine the cost-effectiveness of vaccination against herpes zoster (HZ) and post-herpetic neuralgia (PHN) in individuals aged 60 years and older in Belgium.

Methods:

A Markov model was developed to compare the cost-effectiveness of vaccination with that of a policy of no vaccination. The model estimated the lifetime incidence and consequences of HZ and PHN using inputs derived from Belgian data, literature sources, and expert opinion. Cost-effectiveness was measured by the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life-year (QALY) gained.

Results:

Vaccination in individuals aged 60 years and older resulted in ICERs of €6,799 (third party payer perspective), €7,168 (healthcare perspective), and €7,137 (societal perspective). The number needed to vaccinate to prevent one case was 12 for HZ, and 35 or 36 for PHN depending on the definition used. Univariate sensitivity analyses produced ICERs of €4,959–19,052/QALY; duration of vaccine efficacy had the greatest impact on cost-effectiveness. Probabilistic sensitivity analysis showed at least a 94% probability of ICERs remaining below the unofficial €30,000 threshold.

Discussion:

Key strengths of the model are the combination of efficacy data from a pivotal clinical trial with country-specific epidemiological data and complete sensitivity analysis performed. Main limitations are the use of non country-specific PHN proportion and non Belgian disease-specific utilities. Results are comparable with those recently published.

Conclusions:

HZ vaccination in individuals aged 60 years and older would represent a cost-effective strategy in Belgium.     

Editorial

An Almost Ideal Demand System (AIDS) was utilized to model the United States demand for domestic and imported tobaccos. The model, which includes equations for domestic flue-cured tobacco, domestic air-cured (burley) tobacco, oriental tobacco, and imported flue-cured and burley tobacco, incorporates the impact of economic factors as well as changes in consumer tastes. In this model homogeneity was rejected under certain conditions, but symmetry could not be rejected. These results suggest that imported flue-cured and burley tobacco, to a limited extent, is a substitute for domestic flue-cured tobacco and is a complement for domestic air-cured tobacco. The trend toward lower average nicotine content of domestic cigarettes is shown to have a detrimenta1 effect on the demand for domestic flue-cured tobacco, but a beneficial impact on domestic air-cured (burley), and imported oriental tobaccos.     

Interest Income Tax Evasion,the EU Savings Directive and Capital Market Effects*

The EU Savings Directive has been celebrated as a major political breakthrough in coordinating taxation in Europe. Against this background, the present paper evaluates the real‐world effects of this directive. The directive has left a loophole by providing grandfathering (exemption from withholding tax) for some securities. In this paper, we compare the pre‐tax returns of exempt bonds and comparable taxable bonds. If working around the Savings Directive is difficult for income tax evaders in Europe, then investors should be willing to pay a premium for bonds that are exempt from the withholding rate. Conversely, if such a premium is absent, then this suggests that the supply of existing loopholes (exempt bonds included) is large enough to allow tax evaders to continue evasion at no additional cost. The findings of our study are in line with this latter interpretation.     

Migration and Americanization: The special case of Belgian economics*

One of the distinguishing features of Belgian economics is that, from the early 1920s, so many of Belgium's best economists pursued postgraduate studies at top American universities, a case of ‘temporary’ migration. This was made possible by the fellowships granted by the Commission for Relief in Belgium, a legacy of the First World War. After a stay in the US of a few years, most returned to Belgium. However, they maintained strong links with the US. Also, they tried to recreate in Belgium the most valuable elements of their American experience. It would lead to a strong and early Americanization of Belgian economics. Moreover, they were at the forefront of several initiatives to organize economics on a European scale, such as the European Economic Review and the European Economic Association.
