The Covid-19 pandemic caused an unusual population mortality rate. This paper aims to determine a causal relationship and its incidence between the Technical Efficiency (TE) of health systems and the Covid-19 mortality rate. Using the Data Envelopment Analysis (DEA) methodology and the OLS, GLS and 2SLS adjustment methods, in 108 countries grouped according to per capita health expenditure, it was found that a 1% increase in the TE of the health systems of the analyzed countries reduces the number of deaths from Covid-19 by between 61 and 127 per hundred thousand inhabitants, concluding that the efficiency of expenditure was transcendental in the prevention of mortality caused by the pandemic.

It is expected that this research will contribute to the economic literature on the importance of evaluating the impact of public policies in order to improve the allocation of financial resources as well as contribute to the productivity and efficiency of companies. For this, the REINDUS program has been taken as a reference, one of the most representative instruments of industrial policy in Spain, which grants, among others, soft loans to companies with the purpose of promoting industrial development through business improvement and efficiency of the productive sectors. The period analyzed includes calls between 2009 and 2014, based on 689 SMEs with required information. Therefore, the objective of this research is focused on advancing in the specification about the usefulness of soft loans, as an instrument of industrial policy, from the perspective of productivity and efficiency, in this way, it will be possible to contribute to the development of indicators and policies for monitoring and adapting the aid programs to companies, in order to optimize the allocation of these resources and generate the desired effects in the various public policies to support the development of the business fabric in Spain. To study the improvement of productivity through the total change of the Total Factor Productivity (TFP), the Malmquist Index, initially introduced in the context of the consumer theory by Malmquist (1953), and the decompositions of Färe, Grosskopf et al. (1989, 1994) that assumed constant returns to scale using data envelopment analysis techniques, DEA (Orea and Zofío, 2017). Following this decomposition, we can calculate: (i) the productivity behavior (malmquist), (ii) the change in efficiency (effch), (iii) the technological change (tech). Färe, Grosskopf et al. (1994), provided the decomposition of efficiency into scale efficiency (out / in-.scalech) and into pure efficiency change (pure.out / in.effch), finally, following Färe, Grifell-Tatjé et al. (1997), we can obtain the marginal rate of substitution (input-biased technical change -ibtech-) and the marginal rate of product transformation (output-biased technical change -obtech-) in presence of technological change and the magnitude of technical change -matech-. To perform the necessary matching for the proposed analysis and because we are facing a quasi-experimental design, a combination of techniques is proposed, such as the analysis of Differences in Differences and the Matching by Nearby Neighbors using Mahalanobis Distance, to try to reduce the risk of bias in the estimation, since simple matching cannot account for unobservable characteristics (Pérez and Moral, 2015). To match the control and treatment groups, a model is used in which the criteria of financial capacity prevail, widely recognized by the literature on credit risk as determining factors when establishing the financing capacity of companies. The analysis of the Total Factor Productivity (TFP) and its components in the study period, shows that the treated companies reduced their productivity on average, for example, the treated companies in the 2009 call shown a reduction in the TFP (malmquist) between 2012 and 2008 of 9%, while in the control companies the reduction was 7%. In the best case, call 2014, practically the same level of productivity was maintained among those treated (loss of 1% between 2013 and 2017). It was expected, therefore, that the investments made would have a positive effect on productivity, however, the results show the opposite, in fact, if technological change (tech) is observed, which implies a shift of the production frontier, presented a significant setback, it is striking, since it was the one that most contributed to the negative variation of the TFP in the analyzed period. The improvements came from positive changes in efficiency (effch), probably motivated by the reduction in wage costs after the crisis of 2007 and in line with the evolution of the labor market and the destruction of jobs in these years. Following the Färe decomposition, Grifell - Tatjé et al. (1997) we calculated the alternative directions of the bias of the inputs in the technological change. The STAF / FIAS input pair presented a bias towards the use fixed assets compared to savings in personnel expenses in the treated companies when technological change occurs, the same occurs with the treated companies in the FIAS / MATE relation, To the extent that this input is used, it generates savings in the production needed materials. In general, the impact of the program did not show a positive effect within the treated companies compared to the control companies, in fact, there were setbacks in productivity (malmquist), mainly due to the technological setback (tech-frontier shift), which was largely offset by change in efficiency (effch-catch up). This technological decrease supposes a deviation from the policy objectives on the results obtained, therefore, emphasis will have to be placed on carrying out an exhaustive analysis of possible agency conflicts within the companies, on adjustment costs not contemplated in the policy, the amount of the loans and the execution of the projects proposed in such a way that the disbursements are subject to milestones that guarantee their execution. It is proposed to design a monitoring strategy based on information technologies to facilitate and promote feedback on the objectives that allows managers to have up-to-date, quality, and robust information, recognizing that such responsibility also falls on the beneficiaries of the policy, since it is a public instrument on which companies must be accountable to society, making it a fundamental requirement to provide periodic information by the beneficiary to monitor the progress of the investments contemplated in the investment projects contributed in the time of application. Likewise, greater involvement is required from the managing entity in the realization of the business plans, mainly in the actions immediately after the disbursement, as carried out by private investment funds. This work contributes to the economic literature a detailed analysis about the impact of the soft loans of the REINDUS program on the productivity and efficiency of the companies in the period 2009 to 2014, identifying the sources of the observed change on which the policy objectives can be adjusted to maximize its effectiveness, there is no previous work in this regard. The main limitation of this work was presented in the information available for the realization of the paper. The aid Managing Administration (Dirección General de Industria y de la Pyme in 2017) refers to the Boletín Oficial del Estado where the results of the respective calls are published as the only source of information available to third parties, with the limitation that this implies. It was not until the results of the 2016 call that the rejected companies began to be published and in 2018 the scores obtained by the companies benefited exclusively, which indicates that there is a path to consolidate the institutionalization of the impact evaluation of public policies within of the Public Administration.

Biotechnology has been for some years one of the fundamental sectors for Cuban economic development. Its important role is given, among other elements, by the growing nature of its exports of high value-added products. However, this being a highly competitive international sector, many marketing decisions present a high component of uncertainty. At the same time, some mathematical tools have been developed in order to reduce the subjective nature of business decision making and with it, uncertainty. This paper proposes a procedure for the estimation of prices in the export of biotechnological products, based on fuzzy subset theory and data envelopment analysis. The proposal is applied to the biosimilar product Hebervital and it is concluded that the procedure reduces uncertainty in decision-making. In particular because of the use of triangular fuzzy numbers, which greatly support the negotiation process. [ABSTRACT FROM AUTHOR]

This paper shows the results of a research study whose purpose is to evaluate the technical efficiency of institutions of higher education in Colombia during the years 2011-2013 by applying the data envelopment analysis and data mining techniques. With data envelopment analysis, it is determined the technical efficiency and data mining allows to discover hidden information. The result of the combination of these techniques allows to establish prediction rules based on a group of management indicators that can be used by the designers of educational policies to determine the reasons for inefficiency of institutions of higher education. The information provided by the Ministry of National Education was used as a source for the data. It was observed that seven of the 32 institutions considered had an efficiency of 100% during the period of study. [ABSTRACT FROM AUTHOR]

This paper proposes the incorporation of data envelopment analysis (DEA) to the methodology for the construction of a sustainable adjustable inmotic storage hall (MEINASA in spanish), in order to make it more robust for application in the design of production systems for warehousing of non-perishable products, given the interests of the client and the buyer-supplier echelon in the supply networks. MEINASA is used in a real design case of a distribution center for a manufacturer of faucets and DEA is applied to calculate the efficiency index of the 16 generated proposals, obtaining five efficient designs which can be assigned as peers for improvement of the remaining ones. The results suggest possible modifications that can be made on the designs identified as inefficient. [ABSTRACT FROM AUTHOR]

Assessing the efficiency of commercial negotiators from the determination of the elements that characterize their profiles is a useful tool for elaborating actions plans that contribute to the improvement of the Cuban enterprises' negotiating activity. A procedure for determining technical efficiency of commercial negotiators in Cuban enterprises is presented in this paper, by the use of a nonparametric technique of data enveloping analysis (DEA). The use of this procedure in Cuban enterprises linked to foreign commerce activity allowed determining technical efficiency indexes of commercial negotiators from these entities as well as identifying elements that determine this efficiency.

This paper presents a new temporal data envelopment analysis model that overcomes some weaknesses of the window analysis and Malmquist Index models reported in the literature. Time series are constructed with manufacturing data from the National Administrative Department of Statistics. For each series the best of a set of ARIMA models is selected, and a forecast for two periods is established. Changes in efficiency of the five largest industrial centers of Colombia are analyzed. For that, variables are located at different time positions including forecasts. The implementation of the new model shows the benefits of considering more than two periods. It also shows how classical Malmquist method is improved by changing deterministic univariate variables by time-series. Based on the results it is concluded that the method is close of being a data envelopment analysis in real time. [ABSTRACT FROM AUTHOR]

This paper presents the results of an empirical study whose main purpose is to determine the scores of technical efficiency (ET), pure technical efficiency (EPT) and scale efficiency (EE) in the district educational institutions (IED) of Santa Marta through the data envelopment analysis, and, at the same time, to establish protocols of improved for inefficients institutions. Using CCR-O (Charnes, Cooper y Rhodes) and BCC-O (Banker, Charnes y Cooper) models, the study evaluates the relative efficiency of 44 public institutions, which are analyzed in two categories: Group 1 (IE with less than or equal to 2000 students) and Group 2 (IE with more than 2000 students). In general terms, the empirical findings reveal that 20% of the evaluated institutions are CCR-O efficients and 43% are BBC-O efficients. On the other hand, 80% of inefficient educational institutions have operational scale (EE) issues and 57% also have administrative difficulties (EPT). The results also show that the worst extent of performance is IE John F. Kennedy (ET=0.304), (EPT=0.886) and (EE=0.343). Moreover, the IE Normal Superior para Señoritas (efficient IE), which is evaluator of 17 inefficients institutions, and San Francisco Javier College, which evaluates 15 inefficients institutions, are configured as the institutions that present the best practices and in role models. Finally, IED Nueva Colombia, IED Normal Superior San Pedro Alejandrino and IED Liceo del Sur Víctor de Lima are efficients institutions, however, they are not evaluators of none inefficient institution.

Resumen Este trabajo propone un modelo para la evaluación organizacional que se comprueba empíricamente con una muestra de 37 bibliotecas integradas a la universidad pública en la ciudad de Río de Janeiro, muestra que representa más del 80 % de la población y cuyos datos corresponden al periodo 2000-2007. El enfoque propuesto consta de tres pasos. En primer lugar, sobre la base de un modelo dea (Data Envelopment Analysis), se calculan y se comparan las puntuaciones de eficiencia para cada una de las bibliotecas en el periodo 2000-2007; estos resultados permiten obtener una clasificación de las bibliotecas en función de su eficiencia relativa. El segundo paso consiste en identificar las acciones cuantitativas “óptimas” que permitan conducir a una biblioteca clasificada como “ineficiente” hacia el conjunto de las unidades eficientes. Esta cuantificación también sirve para evaluar los movimientos efectivos observados de un año a otro. En el tercer paso se recurre a la hipótesis Markoviana para establecer el desempeño esperado en el largo plazo en términos de la distribución del sistema entre los estados de “efciencia” o “inefciencia”. Mediante pruebas no paramétricas se examina la asociación entre la eficiencia (cuantificada en calificaciones anuales) y el perfil demográfico. En la mayoría de las pruebas no se encontraron diferencias significativas entre las puntuaciones obtenidas en el periodo analizado This paper presents a stepwise approach to organizational assessment from an efficiency standpoint. The empirical illustration originates from data referring to the period 2000-2007 and collected from a sample of 37 libraries affiliated to a federal university in Rio de Janeiro; this sample covers more than 80% of this affiliated universe. Employing efficiency scores computed from estimated dea (Data Envelopment Analysis) models, the stepwise approach ranks libraries and provides proefficiency allocative corrections. In the third step, long run evaluation is accomplished by Markovian analysis. Nonparametric tests are applied to investigate whether efficiency might be associated to demographic attributes. Findings generally indicated that efficiency scores were undistinguishable in the period. Although public libraries were the object of this study, the researchers argue that the approach is generally valid; as such the model can be applied to private organizations as well.

The aim of this paper is to study the level of efficiency in the sector of cooperative savings banks in Spain, using a non-parametrical approach by means of the DEA analysis. (DEA - Data Envelopment Analysis). Due to this, we start by a restricted approach that includes inputs such as business banking, staff costs, depreciation and financial costs, the traditional outputs being, loans and the securities portfolio. Subsequently, an incremental approach is proposed, extending the outputs of cooperative savings banks to bank operations, preferably with partners and the requirement to have a large workforce, with a reduced net profit in comparison with the rest of the banking entities. After discriminating the size of the cooperative savings banks, the future strategic response of the most important savings banks is given, according to the volume of Average Total Assets.

There is no competitiveness problem when there are no competitors. For that reason, differentiation constitutes a key strategy for the company; then it contributes to generate a captive market for the product reducing this way its competition. Supposing that differentiation is not possible, costs and efficiency appear as the only possible way (Esteban y Coll, 2003). Focusing the attention in the last one, this paper analyzes -by employing a non parametric methodology: the data envelopment analysis (DEA)- the technical efficiency of textile industry in Spain. For that, we have studied a group of companies of each and every activity that constitute the textile industry following the classification CNAE93. The evaluation has been done from financial-economic information obtained from the profit and losses account and balance sheet. [ABSTRACT FROM AUTHOR]
