Economic Value and Historical Scenic Beauty: The Case of Chinampas (Raised Beds) in Xochimilco, UNESCO World Heritage Site, Mexico  [PDF]
Daniel A. Revollo-Fernández
Natural Resources (NR) , 2015, DOI: 10.4236/nr.2015.64024
Abstract: This article estimates the historical scenic beauty’s economic value that tourists do have to preserve a pre-Hispanic farm production system dating from XIV to XVI century to be known as chinampas (raised beds) and is located in Mexico City. Therefore, in order to do this, surveys are performed and by contingent valuation (CV), the willingness-to-pay (WTP) is estimated. The best estimation points out that tourists are willing to pay 24.4 dollars around each year, and by means of such estimation, it is estimated that the cultural service’s economic value to preserve raised beds is between US$ 3000 and US$ 3700 per hectare. Such found value must be used as another input for decision makers when dealing with projects and/or policies facing contrary purposes. The analysis is innovative in the sense that there is almost no CV literature to estimate the economic value of historical scenic beauty.
Does Money Fly? The Economic Value of Migratory Birdwatching in Xochimilco, Mexico  [PDF]
Daniel A. Revollo-Fernández
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.66061
Abstract: This paper estimates the economic value that national and international birdwatchers have to keep an urban wetland in this case, Xochimilco (Mexico), as a place of rest, food and/or shelter for migratory birds from North America. For this purpose, it is resorted to surveys and contingent valuation that estimates the willingness to pay (WTP) per year of these watchers. The best estimate indicates that national watchers are willing to pay approximately US $79 per year, while international, US $296. Using these estimates, it is calculated that the economic value of the bird migration environmental service for this urban wetland is located between US $2836 and US $3999 per hectare. This found value can work as an input for decision makers when faced with projects and/or policies that may face different objectives.

Fernández,Rodrigo A.;
Visi?3n de futuro , 2011,
Abstract: this paper estimates the private returns on investment in education. annual rates of return were estimated for the conglomerates in northeastern argentina (nea) between the third term of 2003 and third term of 2009, using the basis of micro-data from the permanent household survey (eph). in yield estimation were proposed models for men and women to correct the sample bias problems evidenced in their low participation in the economically active population (pea). the results show a higher return to education for men than for women, a different yield in the agglomerate posadas above average of nea, a high penalty function in the informal economy sector (black work) a direct relationship between company size and yields of men at the same time would bring report less volatility in its temporal evolution.
Hacia una Nueva Conceptualización del Homo-Economicus - Aportes a la Teoría del Consumidor
Fernández,Rodrigo A.;
Visi?3n de futuro , 2009,
Abstract: in the present paper a critical revision of some assumptions that underlie in the theory of the neoclassical consumer, specially those referring to the characteristics of the economy or consuming agent, which has among other characteristics an extreme rationality and a tendency towards the mathematical optimization in the consumption decisions. some historical and methodology aspects are reviewed that explain the origin and development of the homo-economicus. among the critics stand out: the methodological individualism, preferences exogeneity, preferences individuality, opposition between preferences and values, instrumental rationality, and information limitless management. in the paper one argues that the form in which it has been constructed, from the economy theory and especially of the consumer theory, the homo-economicus corresponds to a traditional philosophical approach, whereas some guidelines set out from heidegge's existentialist philosophy to surpass the limitations.

RENDIMIENTOS DE LA EDUCACIóN EN EL NORESTE ARGENTINO EVOLUCIóN RECIENTE Y ESTRUCTURA ACTUAL
Fernández, Rodrigo A.
Visi?3n de futuro , 2011,
Abstract: En el presente trabajo se estiman los rendimientos privados de la inversión en educación. Se estimaron las tasas anuales de rendimiento, para los aglomerados del Noreste Argentino (NEA), entre el tercer trimestre del 2003 y tercer trimestre de 2009, utilizando la base de micro-datos de la Encuesta Permanente de Hogares (EPH). En la estimación del rendimiento se propusieron modelos diferentes para los hombres y mujeres, de forma de corregir en estas últimas los problemas de sesgo muestral, evidenciados en su menor participación en la Población Económicamente Activa (PEA). Los resultados obtenidos muestran un rendimiento de la educación mayor para los hombres que para las mujeres, un rendimiento diferencial en el aglomerado Posadas superior a la media del NEA, una elevada penalización por desempe arse en el sector informal de la economía (trabajo en negro) y una relación directa entre el tama o de la empresa y los rendimientos de los varones que a la vez reportaría una menor volatilidad en su evolución temporal.
