Inflation and income inequality: a shopping-time aproach: (Forthcoming, Journal of Development Economics)

Our work is based on a simpliÖed heterogenous-agent shoppingtime economy in which economic agents present distinct productivities in the production of the consumption good, and di§erentiated access to transacting assets. The purpose of the model is to investigate whether, by focusing the analysis solely on endogenously determined shopping times, one can generate a positive correlation between ináation and income inequality. Our main result is to show that, provided the productivity of the interest-bearing asset in the transacting technology is high enough, it is true true that a positive link between ináation and income inequality is generated. Our next step is to show, through analysis of the steady-state equations, that our approach can be interpreted as a mirror image of the usual ináation-tax argument for income concentration. An example is o§ered to illustrate the mechanism.

Implications of ernbodied technological change for development economics

Employing a embodied technologic change model in which the time decision of scrapping old vintages of capital and adopt newer one is endogenous we show that the elasticity of substitutions among capital and labor plays a key role in determining the optimum life span of capital. In particular, for the CD case the life span of capital does not depend on the relative price of it. The estimation of the model's long-run investment function shows, for a Panel data set consisting of 125 economies for 25 years, that the price elasticity of investment is lower than one; we rejected the CD specification. Our calibration for the US suggests 0.4 for the technical elasticity of substitution. In order to get a theoretical consistent concept of aggregate capital we derive the relative price profile for a shadow second-hand market for capital. The shape of the model's theoretical price curve reproduces the empírical estimation of it. \lVe plug the calibrate version of the long-run solution of the model to a cross-section of economies data set to get the implied TFP, that is, the part of the productivity which is not explained by the model. We show that the mo dei represent a good improvement, comparing to the standard neoc!assical growth model with CD production function and disembodied technical change, in accounting the world diversity in productivity. In addition the model describes the fact that a very poor economy can experience fast growth based on capital accumulation until the point of becoming a middle income economy; from this point on it has to rely on TFP increase in order to keep growing.

After structuralism, a development alternative for Latin America

The paper, first, summarizes Latin American structuralism, and offers reasons why it was so influential and durable in the region, as it attended to real demands, and was part of 1950s’mainstream economics. Second, says why, with 1980s’Great Crisis, structuralism eventually ended itself into crisis, as it was unable to keep pace with historical new facts, particularly with the industrial revolution or takeoff, that made Latin American economies intermediary, still developing, but fully capitalist. Third, it lists the consensus that today exists on economic development. Forth, opposes “official orthodoxy” to “developmental populism”, the former deriving from neoclassical economics, the later from structuralism, and offers, in relation to six strategic issues, a progressive development alternative.

Pluralism in economics: from epistemology to hermeneutics

The objective of this paper is to bring elements from the philosophical movement of hermeneutics and pragmatism to the discussion on methodology in economics, with a specific concern on the theory of truth. Our aim is to present the concept of the hermeneutic space, developed by the philosopher Richard Rorty, as a rational justification for pluralism in economics. We consider the hermeneutic space an interesting concept which should allow us to overcome the void left by the incapacity of epistemological theories to explain the evolution of sciences. It defends the idea that our culture, values and ways of interpreting things are what build the sciences, not any closed epistemological method. In this sense, pluralism is nothing more than letting the hermeneutic space work, without epistemological barriers, and understanding that this is desirable for the future development of economics as a science. This approach differs from all other methodological justifications for pluralism because it does not rely on any epistemological method, but assumes that the hermeneutic space can entirely fulfill the gap created by them

Law and economics in the civil law world: the case of Brazilian Courts

Conventional wisdom holds that economic analysis of law is either embryonic or nonexistent outside of the United States generally and in civil law jurisdictions in particular. Existing explanations for the assumed lack of interest in the application of economic reasoning to legal problems range from the different structure of legal education and academia outside of the United States to the peculiar characteristics of civilian legal systems. This paper challenges this view by documenting and explaining the growing use of economic reasoning by Brazilian courts. We argue that, given the ever-greater role of courts in the formulation of public policies, the application of legal principles and rules increasingly calls for a theory of human behavior (such as that provided by economics) to help foresee the likely aggregate consequences of different interpretations of the law. Consistent with the traditional role of civilian legal scholarship in providing guidance for the application of law by courts, the further development of law and economics in Brazil is therefore likely to be mostly driven by judicial demand.
