In this documental research work they are presented as the origin of  fideicomisos de infraestructura y bienes raíces or FIBRA, the development of this type of investment instruments in the world, as well as the legal and fiscal structure of the FIBRA in Mexico. For this, the Real Estate Investment Trust or REITs are presented, which are an investment mechanism that finance large real estate not only in America, but throughout the world. This allows the public money market to participate in these investments, although in their history they have presented different risks and yields due to the legal framework of their countries of origin. In Mexico, the legal structure of the FIBRA is very robust and similar to that of the USA. One of the engines of these instruments is the tax exemption they offer; for this reason, the case of Spain has not awakened, it still does not motivate the interest of the market insofar as it does not offer these tax benefits. There is a great appetite all over the world for these instruments. The big question will be to what extent are viable options to use them as a diversification mechanism in order to decrease risk or increase performance.Key words: alternatives on investment, financial performance, financial portfolios, Mexican REIT, MTPJEL: G400, G110 & G150. Resumen. En este trabajo de investigación documental se presentan como el origen de los fideicomisos de infraestructura y bienes raíces o FIBRA, el desarrollo de este tipo de instrumentos de inversión en el mundo, además de la estructura legal y fiscal de los  FIBRA en México. Para ello se presentan los Real Estate Investment Trust o REITs que son un mecanismo de inversión que financian grandes propiedades inmobiliarias no sólo en América, sino en todo el mundo. Esto permite que el mercado de dinero público participe en estas inversiones, aunque en su historia han presentado diferentes riesgos y rendimientos debido al marco legal de sus países de origen. En México, la estructura legal de los FIBRA es muy robusta y parecida a la de EUA. Uno de los motores de estos instrumentos es la exención fiscal que ofrecen; por ello, el caso de España no han funcionado  estos instrumentos  y  siguen sin motivar el interés del mercado en la medida en que no ofrece estos beneficios fiscales. Existe un gran apetito en todo el mundo por estos instrumentos. La gran pregunta será hasta qué punto son opciones viables para usarlos como mecanismo de diversificación a fin de disminuir el riesgo o aumentar el rendimiento.Palabras clave: alternativas de inversión, desempeño financiero, FIBRA, portafolio financiero, TPM","PeriodicalId":145148,"journal":{"name":"Revista Innovaciones de Negocios","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126347041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results suggest that the airlines studied use similar internationalization strategies, which are based on strategic alliances with other airlines in order to offer a better service to their passengers. They were also identified as the main characteristics of these airlines that are strong in their domestic market (especially Aeromexico) and then they start to expand their operations abroad.

However, what is perhaps one of the most complex structural strategies is to redesign the wages and benefits of employees, to get a model that has a tax benefit for the organization, lightening payroll tax.
