The force interpretation of evolutionary theory: scope and limits

2016

La teoría evolutiva suele entenderse como una teoría causal donde las causas principales del cambio evolutivo son identificadas con la selección natural, la deriva genética, la mutación y la migración. Siguiendo este razonamiento, muchos biólogos y filósofos de la biología han estructurado la teoría evolutiva de forma análoga a la mecánica newtoniana, entendiendo la teoría evolutiva como una teoría de fuerzas. El punto clave en el que se sustenta la analogía, es que la estructura de la mecánica newtoniana permite identificar los elementos causales del sistema de interés. De esta manera, la teoría evolutiva encuentra una útil imagen explicativa del fenómeno evolutivo, estructurándose como un…

A Spatial Difference-in-Differences Estimator to Evaluate the Effect of Change in Public Mass Transit Systems on House Prices

2014

Evaluating the impact of public mass transit systems on real-estate values is an important application of the hedonic price model (HPM). Recently, a mathematical transformation of this approach has been proposed to account for the potential omission of latent spatial variables that may overestimate the impact of accessibility to mass transit systems on values. The development of a Difference-in-Differences (DID) estimator, based on the repeat-sales approach, is a move in the right direction. However, such an estimator neglects the possibility that specification of the price equation may follow a spatial autoregressive process with respect to the dependent variable. The objective of this pap…

The concept of integrated profit offers a theoretical framework for a holistic analysis of contract goals between agricultural producers’ groups and agri-food sector. The theoretical background applied in this paper is the contract theory. The primary purpose being the identification of vertical coordination forms between producers’ organizations and agri-food sector. Consequently, the specific goal was to recognize price mechanisms in contracts and their analysis in the context of the integrated profit (only in the field of coordination). The research focused on contracts signed in 2014 between groups operating on poultry market and their first buyers. The survey (collection of primary dat…
