How to motivate faster growth in Colombia : the leading sector strategy revisited

This paper reproduces two public lectures given at an Incolda conference in Bogota, October 1, 2002 on «La Realidad de la Economía Colombiana ». It reviews the great structuralchanges in output and employment over recent decades and how macroeconomic policies can strengthen or weaken the natural forces underlying these changes. It distinguishes between potentially inflationary policies designed to increase demand ina monetary sense, and those that focus on institutional changes that enhance competition and mobility. It explains how inflation distorts the allocation of resources, and why it especially harms long-term housing finance and exports. It explains the logic of Lauchlin Currie¿s leading sector theory of growth and shows whyand how housing and exports can be given special protection to accelerate development.

Updating Beliefs: Are economic agents inspired by rational action or according to ones hopes and fears?.

The purpose of this investigationwas to simulate a real life scenarioand explore the way economicagents update their beliefs. Do theyupdate according to what theyhope? Or do they update inspired byrational behavior?We mimicked the environment whicha recently high school graduate faceswhen entering college to see how astudent updates his beliefs in regardsto his classroom position. We examinedhow economic agents envisagethemselves through and through collegeand see if they update their beliefsabout a hypothesis A in the lightof new evidence B, or if they updatetheir beliefs subject to what theychoose they hope. In this sense weexplored the possibility of setting asidethe neoclassical assumption thatagents are anything more than hyperrational naïve optimizers acting on perfect (and in some cases, limited information)in order to turn back to anolder tradition in economic theory, thatis agents are recognizably human.
