Given that demand for durable goods is not constant over time, we propose in this article a transformation of the utility function, which accounts for discrete time and for the effect of different levels of income in the utility of buying. With this, the original Coase paradox will collapse. The...

We examine a model that generalizes the standard buffer-stock model of savings to accommodate durables, nondurables and a collateralized liquidity constraint, with and without adjustment costs in the durables market. Since there is no known analytical solution to the model, we solve it...

We develop a vertical differentiation game-theoretic model that addresses the issue of designing free software samples for attaining follow-on sales. When software samples are akin to durable goods, a Monopolist giving a free sample away is likely to engender the cannibalization of sales of its...

Models of durable goods with network externalities that set instantaneously have emphasized that a monopolist selling those goods has too high an incentive to introduce new vintages of the durable good, to make previous vintages (already bought by consumers) obsolete. This is referred to as...

Resumo: O consumidor de um bem durável tem uma expectativa face ao momento futuro, que é caracterizada pelo usufruto de uma inovação do produto introduzida através da publicidade experimentável, a qual contribui para a diminuição do preço dos bens duráveis no momento actual. A...

We wish to study optimal dynamic nonlinear income taxes. Do real world taxes share some of their features? What policy prescriptions can be made? We study a two period model, where the consumers and government each have separate budget constraints in the two periods, so income cannot be...

El objetivo de este paper es realizar una descripción del caso brasileño, en lo que hace a la salida de un sistema en el cual el ancla nominal de la economía era un tipo de cambio semi-fijo, hacia un régimen de flotación “cuasi” limpia de la moneda, en el que el ancla de la economía...

El tema de la inflación ha sido uno de los más debatidos en los últimos meses. Los incrementos de precios registrados en el primer trimestre de 2005 han avivado la discusión. Este trabajo muestra que el problema está lejos de estar fuera de control y que determinadas medidas de política...

Territorial appointees to an independent central bank (e.g. District Federal Reserve Banks’ presidents, Governors of national central banks at the ECB’s Governing Council) are liable to confront a “role conflict” stemming from a duality of loyalties and allegiances - to the home regional...

Current monetary policy involves the manipulation of the Central Bank interest rate (the repo rate), with the specific objective of achieving the goal(s) of monetary policy. The latter is normally the inflation rate, although in a number of instances this may include the level of economic...
