This paper explores the effect of port's service time, particularly the mean and variability, on shippers' total landed costs to determine the competitive position of the port and derive recommendations for the strategic design of port services.

The competitive position of a port is estimated considering the service level offered to the end-users of the port such as port service time, its variability and its effect on the total landed costs observed by the port users. The proposed methodology is meant to help ports to determine the required service time levels to maintain or gain a competitive advantage against other ports, in terms of attracting common hinterland's customers.

Results show the advantages of considering service levels factors to determine the competitive position of a port, and what are the minimum characteristics required to capture more traffic volumes, that can help port managers to take strategic design decisions to better position the port in the current fierce market.

The proposed methodology is illustrated by considering a case study, which is the Port of Guaymas in Mexico. Data was not directly collected by the port, but based on interviews with shippers and public information, a representative case is presented. Due to a confidentiality agreement with the Port, specific references for most of the data used to estimate the model's parameters are not provided. The analysis is intended to show the potential value of this mechanism and can be used for evaluating the competitive position, from a high-level perspective, of any port to determine potential hinterland by improving the service level of the port.

The existing literature on port choice and port competition has not previously considered the effect of port service levels under the perspective of total landed costs of the users, being this paper a contribution to fulfill this gap.

This paper aims to present a closed-loop supply chain (CLSC) optimization problem for a perishable agricultural product to achieve three pillars of sustainability, including minimizing total network costs and carbon dioxide emissions from different network activities and maximizing responsiveness to demands simultaneously.

The research problem is formulated as a multi-objective mixed-integer linear programming model, and classical approaches, including the LP-Metric and weighted Tchebycheff method, have been applied to solve the optimization model. A set of test problems has been proposed to validate the model, and the results are presented.

Computational time to find Pareto optimal solutions by using the weighted Tchebycheff method was twice as much as that of the LP-Metric method. Also, the result of the study is a mathematical model that can be applied to other products that are close to the fruit, such as vegetables.

The present study is limited to fruits supply chains and the inventory is considered at the distribution centers only. The study also considers only one type of transport.

The paper can assist supply chain managers to define strategies to achieve a sustainable CLSC network configuration for the fruits.

This study is one of the early studies to consider environmental indicators in fruits supply chain design along with two other indicators of sustainability, namely, economic and social indicators. Therefore, this can help supply chain managers to achieve sustainability by optimizing location decisions, inventory quantities and flow between facilities.

This paper analyzes alternative performance evaluation models applied to equity mutual funds under conditional and unconditional approaches in the Brazilian market.

The analysis is conducted using CAPM's single factor, Fama–French three and five factors, under their conditional and unconditional versions in a sample of 896 equity mutual funds from 2008 to 2019.

The results suggest that the use of three- or five-factor models is especially relevant to reduce the effect of market anomalies in performance assessment. Additionally, results show that conditional approaches, adding time-varying alphas and betas with macroeconomic variables, provide higher explanatory power than their unconditional peers.

The results are relevant in the unique economic environment characterized by historically high interest rate and high market volatility.

The purpose of this paper is to present the progress and trends of the literature on art as an investment and to outline potential research lines to be developed.

This work gathers, analyses and critically discusses the attributes of investments in art in general, and in Latin American art in particular.

Most studies report that art (art in general, and Latin American in particular) has offered relatively low but positive real returns, which have tended to be below those offered by stocks and similar to those realized by bonds. Art has a low correlation with other investments.

The literature on the attributes of Latin American art as an investment is limited and new research would help to close the knowledge gap with respect to this segment of the art market as it continues to grow.

Similarly to the research carried out into other segments of the art market, studies on Latin American art suggest that the works of art are worth more, ceteris paribus: the more renowned the artist, the larger the work, whether they were executed in oil, and if they were auctioned at Sotheby’s or Christie’s. The paper also details a series of practical implications for those who participate in the art market.

To the best of the authors’ knowledge, this is the first exhaustive review of the literature on the attributes of Latin American art as an investment. The findings of this study are useful for academics, art collectors, auction houses, gallerists and others who take part in the arts market.

Presentar los avances y las tendencias de la literatura sobre el arte como inversión, y delinear líneas de investigación a ser desarrolladas.

Este trabajo reúne, analiza y discute críticamente los atributos de inversión del arte, en general, y latinoamericano, en particular.

La mayoría de los estudios reportan que el arte (tanto el arte, en general, como el arte latinoamericano, en particular) ha ofrecido rendimientos reales positivos, aunque relativamente bajos, los cuales tienden a ser inferiores de los de las acciones y a ser similares a los de los bonos. El arte tiene una baja correlación con otras inversiones.

La literatura sobre los atributos del arte latinoamericano como inversión es limitada. Es de esperar que nuevas investigaciones permitan ir cerrando la brecha del conocimiento con respecto a esta parte del mercado del arte a la par que éste continúe creciendo.

Los estudios de arte latinoamericano sugieren, similar a las investigaciones sobre otros segmentos del mercado del arte, que las obras de arte valen más, ceteris paribus: cuando el artista es más reputado, a medida que el área de las obras es mayor, si han sido ejecutadas en óleo, y cuando son subastadas en las casas de subastas Sotheby’s o Christie’s. En el trabajo se detallan, además, una serie de implicaciones prácticas para los participantes del mercado de arte.

Hasta donde se ha podido comprobar, esta es la primera revisión exhaustiva acerca de los atributos del arte latinoamericano como inversión. Los resultados de esta investigación son de utilidad para: académicos, coleccionistas de arte, casas de subastas, galeristas, y demás participantes en el mercado del arte.
