Nonparametric assessments of police technical and scale efficiency is challenging because of the ... more Nonparametric assessments of police technical and scale efficiency is challenging because of the stochastic nature of criminal behavior and because of the subjective dependence on multiple decision criteria, which can lead to a more or less efficiency prospect depending on the regulation, necessity, or organizational objective. There is a trade-off between efficiency and effectiveness in many police performance assessments, i.e., efficient departments (producing more clear-ups with a given resource) are crime-specialized or cannot reproduce those good results effectively on more severe or complex occurrences. This study proposes a combined methodology for carrying out efficiency and effectiveness analysis of Police departments. A conditional non-parametric approach, which allows to include crime as an external factor in the analysis, is combined with a non-compensatory ranking based on the PROMETHEE II methodology for the approach illustrated on the multidimensional efficiency and e...

Assuming an equally proportional change in the output/input ratio, we can estimate how many additional medical resource health service units would be required if the number of hospitalizations was expected to increase during an epidemic outbreak. This assessment proposes a two-step methodology for hospital beds vacancy and reallocation during the COVID-19 pandemic. The framework determines the production capacity of hospitals through data envelopment analysis and incorporates the complexity of needs in two categories for the reallocation of beds throughout the medical specialties. As a result, we have a set of inefficient healthcare units presenting less complex bed slacks to be reduced, that is, to be allocated for patients presenting with more severe conditions. The first results in this work, in collaboration with state and mun...

The importance of the negotiation knowledge disclosure in the sequential bargains of participative budgeting is highlighted by an experiment with 162 state-owned companies’ managers and graduate students to present the contribution of the system’s applicability.FindingsA considerable number of Pareto-efficient deliberation agreements are obtained with few interactions when the negotiation strategies and the personality aspects of opponents and stakeholders are ...

Nevertheless, many assessments of productivity still fail to consider non-compensatory preference structures in the measure of the technical inefficiency. This paper proposes a preference elicitation schema, typical of Multi-criteria decision analysis, for the selection of the directional vector in the assessment of a sustainable productivity. The direction choice is based on the weighted aggregation of concordance indexes for each decision criteria on each individual input, such that it represents an index of relative importance according to the decision maker's perspective. The methodology can be used to aid resource allocation and saving, identify benchmarks for efficient practices and more generally for planning environmental policies in many services and industrial organizations. We illustrate the method with an environmental efficiency evaluation of Brazilian Federal Saving Bank branches.

We provide a systematic bibliometric review on the many empirical surveys in the field of efficiency and productivity analysis, the most relevant concepts, areas, overlaps and potentials to explore from its introduction to the most recent surveys. We combine the international ISIC taxonomy of economic activity with the JEL classification system to classify these empirical surveys and to identify the current gaps in the literature. This provides not only the most relevant/generic potential areas for applications (according to the UN's ISIC), but also the most relevant concepts that have been worked on in those applications (according to the JEL codes). We also provide some cluster analysis. This overview therefore provides an interesting guide for future work to develop the whole field.

The implementation of up-to-date productivity and efficiency analysis is indeed important to advance our knowledge in many fields, ranging from the public and regulated sectors to the private ones. This contribution fills a gap in the existing literature and surveys the currently available options to estimate a variety of frontier methodologies using either general or dedicated programs. We present a conceptual mapping of the key terms associated to the surveyed software and outline directions for future research.

The relationship between alcohol and the violent behavior, expressed as branches of hooliganism, ... more The relationship between alcohol and the violent behavior, expressed as branches of hooliganism, is receiving considerable theoretical attention in social and psychological literature along the past decades while empirical researches on that matter are taken for granted. The falling in appreciating such an empirical approach relies on the difficulty it requires to compare two different realities; one with alcohol intake and another without it, in order to evaluate whether it might drive sport spectators into violent behavior, holding everything else constant. This work provides such robust statistical assessment taking into consideration a Brazilian state law 13748 of April 2009, which prohibited the sale of alcoholic beverages in Pernambuco's football stadiums. We consider the effectiveness of alcohol intervention on hooligan behavior by means of non-parametric test and an autoregressive moving average series, resorting to over ten years of data (before and during the criminalization) with regard aggression and unruly conduct committed by fans before in football matches within 3 miles from the stadium. Our results bring support to the decision of Pernambuco State Legislature to abolish in January 2016 the law in favor of the legalization of alcoholic beverages sales.
