It is our purpose here to show the deep relationship between differential rates and their underlying information sets. To accomplish our task, we will make for the following stages: In the first place, we deal with scaled changes along a period and conditional rates of change within a discrete environment. Next, rings and algebras of sets are addressed, so as to provide information sets with a suitable structure and give grounds to differential rates.

The aim of this paper is to conciliate some conclusions of the economic theories of breach of contract and tort law. The main result is that the two efficient alternatives that tort law identifies (negligence rule and strict liability with a defense of contributory negligence) are mirrored by two efficient ways of defining contract damages. The first consists of forcing the debtor to pay expectation damages but limiting the level of the creditor’s reliance (rule of damage mitigation).

This paper proposes theory and evidence on the relationship between in°ation and the bank's portfolio allocation. The proposed idea rationalized what Rodriguez (1992) pointed out with respect to the Central Bank of Argentina, behaving as a "borrower of ¯rst resort", where banks reallocated their investment from the private sector to government bonds. A main component of in°ation costs is the misallocation of resources, this paper shows a channel through the reallocation of credits, where the credit market for the private sector trend to disappear.

We start out from the hypothesis that limited government leads to low uncertainty and low transaction costs. If political institutions affect the degree of uncertainty and transaction costs, we formally show they should affect the steady state level of income per capita. The impact of uncertainty and transaction costs on income per capita is formalized in a simple capital market model with credit constraints. Empirically, we find increases in political constraints precede economic growth, which is in line with the idea that economic development is driven by political development.

Desde su fundación en 1998, la Universidad del CEMA ha ido incrementando el desarrollo de sus prestaciones académicas: licenciaturas, maestrías, doctorados, programas ejecutivos y seminarios. Esto trajo aparejado un aumento sustancial en el flujo de información que cada uno de los sectores de la Universidad debía capturar, analizar y procesar. 

Sumando a ello, las condiciones tecnológicas actuales, hicieron imprescindible que los alumnos reciban gran parte del apoyo administrativo a sus carreras en forma más eficiente. 

It should be expected from this paper an expansion on some distinctive issues regarding arbitrage portfolios: i) a definition on arbitrage portfolios that enables adjustments to SML and CML environments; ii) sufficient conditions to set up arbitrage portfolios against the SML and CML; iii) feasibility of separation portfolios to carry out arbitrage not only against SML but CML as well; iv) arbitrage of portfolios located in Treynor’s lines by using separation portfolios within a SML environment

La propiedad horizontal es una institución jurídica común en muchos países con derecho civil codificado, que reparte los derechos de propiedad sobre edificios de departamentos u oficinas entre distintos propietarios. Aplicando una versión del teorema de Coase, en este trabajo se analiza a la propiedad horizontal como una solución para establecer derechos sobre activos que producen de manera conjunta servicios susceptibles de ser consumidos en forma individual y conjunta (bienes privados y públicos).
