Una explicación sobre las bases conceptuales y teóricas, así como también un deslinde de los Monetaristas Tradicionales, es el artículo en la blogósfera que el Dr. Scott Sumner ha posteado en la web."Some of us are skeptical of fiscal stimulus, partly because we think monetary stimulus is more efficient for the usual deadweight cost of future taxes reasons, and partly because the central bank might offset the effect by targeting inflation or NGDP. Speaking for myself, I do agree with those who say lower real interest rates increase the number of public investments that meet cost/benefit criteria, and that some types of stimulus such as employer-side payroll tax cuts can “work” when the central bank stubbornly targets inflation or NGDP at the wrong level." escribe el Dr. Sumner sobre la condición de las políticas fiscales (de corte keynesiano) frente a su concepción monetarista de mercado, pero también escribe respecto al monetarismo:"Like monetarists, we assume many different transmission channels, not just interest rates. Money affects all sorts of asset prices. One slight difference from traditional monetarism is that we put more weight on the expected future level of NGDP, and hence the expected future hot potato effect. Higher expected future NGDP tends to increase current AD, and current NGDP."Esta declaración de la concepción de monetarismo de mercado, surge de los blogs hacia las aulas académicas, rompiendo la tradición existente en las escuelas del pensamiento económico norteamericano.Aquí el interesantísimo enlace al blog del Dr. Scott Sumner.http://www.themoneyillusion.com/?p=13353
