El efecto de los supermercados en precios hortícolas
Este es una tesis presentada en la Universidad de Chile.
La característica interesante de este trabajo, es que presenta la capacidad de monopsonio que tienen las grandes cadenas.
Es importante tener en cuenta este efecto sobre la formación de precios en los productores, que los pequeños locales no lo tenían.
Esta capacidad de negociación de las grandes cadenas, hace que los precios para los productores sean mas bajos. ¿Esta reducción de precios, se transfiere a los consumidores? ¿Existe suficiente competencia para que esto sea asi?
Por otro lado, se aumentan los incentivos para que los productores se coordinen en la formación de grupos que permitan aumentar su poder de negociación. El resultado final que se puede intuir de estas observaciones, es la agregación de las empresas en todas las fases. ¿Es esto asi en la realidad?

Una característica que se esta difundiendo a través de todos los países es la concentración de la distribución de productos de alimentación. Las grandes cadenas de supermercados, en algunos casos internacionales, son comunes en todos los países desarrollado.
¿Cuánto poder de monopolio o monopsonio ejercen? La respuesta no es simple.

About Computation...
Computation is one of the most beautiful concept I have had the chance to think about. The more I think about it, the more I find interesting implications.
Of course, in science computation matter!
I went through Copeland article, which lead you to think about the ubiquous definition of computation. In another words, is it everything a computation?
Copeland suggests that everything is suceptible of having a computational interpretation. Which is not the same than saying that everything is a computation.
To interpret an entity as a computation we have to make a model, where we specify a machine and the labeling that link entity and machine.

Wittgenstein and Sraffa
Good ideas, come from everywhere. I can't help thinking about convesations between great men on our story. Reading an interesting article by Sen (2003) "Sraffa, Wittgenstein, and Gramsci", I discover the influence of Sraffa on Wittgenstein.
The later Wittgenstein, was influenced by "the anthropological way of looking at philosophical problems", and there is (one of) the source of "language game". Sraffa, at time, was influenced by Gramsci. Gramsci, although highly original, was influenced by Marx. Gramsci was a founding member of the Communist Party in Italy.
Therefore, from the Wittgenstein of the first world war where the language defines the limits of what we can say, there were many changes. I can imagine the live during the first WW. Let me guess that the horrible results from the first WW, prepare Wittgenstein mind to "the anthropological way". Gramsci and Sraffa were at the right time, to give birth at the concept of "language games".
Just speculations, but this is way I like blooging... :)

If there is no objectivity, there is no science?
This is the feeling that I get from reading Weber and Hayek.
In "The facts of Social Sciences" Hayek says that the concept that we define in social science are abstraction from all the physical properties of the objects. Moreover, the concepts are teleologicals.
Weber on the other hand, says that there is a set of values that frame any interpretation that we make from reality.
Both claims seems to be against the objectivity in social science. So, if there is no objectivity, there is no science?
I think that this question is a sofism that could catch us in a trap. In social science the objectivity is not the same than in natural science.
My intuition lead my thougts toward the question: Is this kind of objectivity, the one mentioned by Weber and Hayek, the unique one?
Let me put it in this way. Someone with a scientific education in economics will do better economic than someone without education in the topic? If the answer is yes, I am tempted to say that there is some accumulated knowledge, that we can produce in economics, in such a systematic way that we can latter on give to students.
This does not guarantee that is the best knowledge, the objective and absolute one, however its allows us to say that there is a certain structure of reference that we are able to make up.
This is not an answer to my original question, however it is an interesting place to keep searching.

The Nature and Philosophy of Science
This link, The Nature and Philosophy of Science, offer a synthesis of the problems related to Philosoph of Science. You can go in there from Baconian Inductivism through Newtonian hpothetico-deductivism and Popperian Falsasionism until the Duhem-Quine problem.
The paper also develop the intuition about why do we need Shaping Principles to observe data. We need criterium to select theories and that is the role of the Shaping Principles. Indeed the problems with how we interpret data are multiple and the paper present some of them.
Although the paper focus on natural science, there is an interesting link between the "Shaping Principles" and the "value-judgemnt" by Weber. Both play the same role: they help to select a theory.
Althought many times the author gives his opinion, without helping to improve the presentation, I still think that this is a good introductory paper, and I strongly recommend it!

Individualism, Capitalism, Keynes and BIEN!
Individualism, has been the main source to explain the efficiency of "the invisible hand", which lead to the foundations of Capitalism (Notice that efficiency does not mean, equality of income).
Keynes, in chapter 24 of The General Theory, announce the mechanism that would lead to the end of "Capitalism",
I am not sure, whether Keynes prediction will eventually work. However, it seems to be that there are organizations that are thinking about alternatives to the pure individualism. It seems to be that there is altruism around and it is possible to coordinate it in order to obtain 'efficient and well distribuited' results.
BIEN, is an alternative way to think about the distribution. Take a look at it, and have a thought.
Keynes, in chapter 24 of The General Theory, announce the mechanism that would lead to the end of "Capitalism",
it would mean the euthanasia of the rentier, and, consequently, the euthanasia of the cumulative oppressive power of the capitalist to exploit the scarcity-value of capital. [...] I see, therefore, the rentier aspect of capitalism as a transitional phase which will disappear when it has done its work.If I am not wrong, Keynes thought that the capital would never change. In other words, that there is not technological change that increase the diversity of capitals, making the 'new type of capital' scarce.
