Abstract

Resumen: En el presente trabajo, se formula y se estima una regla sencilla y empírica de la tasa de interés de intervención del Banco de La República, en el caso de una economía pequena, emergente y abierta; además de la brecha de inflación, construida con las expectativas de los agentes sobre la inflación y la meta de inflación del Banco de La República, y la del PIB rezagada, se introducen otros tres tipos variables, uno para el sector externo, un segundo asociado a la dinámica financiera y crediticia interna y el tercero a la política de intervención del Banco de La República en el mercado interbancario de divisas; en primer grupo, se incluyen la tasa de interés externa, el diferencial de tipos de interés de largo plazo, el precio internacional del petróleo, los desalineamientos del tipo de cambio nominal así como las expectativas tipo chartistas sobre la tasa de cambio; en el segundo, el diferencial entre las brechas observadas del margen de intermediación financiera y su tendencia de largo plazo y la brecha entre la tasa de intervención del banco y la tasa de interés interbancaria; el tercer grupo, se instrumentalizó por las compras de divisas por parte del Banco de La República; la estimación se hace por OLS y los resultados obtenidos para todas las variables son significativos estadísticamente y cuantitativamente; además se superan las pruebas relativas a la normalidad, autocorrelación, correlación serial, heteroscedasticidad, test de Ramsey, test Cusum y Cusum cuadrado, test de multicolinealidad y el de Davidson y MacKinnon, propuesto en Eviews 9, y que es una variante del test de Hausman para probar la endogeneidad. Los resultados abren la posibilidad para otras investigaciones futuras que permitan escudrinar mejor el comportamiento real de un Banco Central. / Abstract : In the present work, it is formulated and estimated a simple and empirical rule of the interest rate of intervention by the Bank of the Republic, in the case of a small, emerging and open economy; in addition to the gap of inflation, built with the expectations of agents on inflation and the Central Bank inflation goal, and lag behind GDP, other three variable types are introduced, one for the external sector, a second group for to the dynamics financial and credit internal, and the third to the policy of intervention from the Bank of the Republic in the interbank currency market; first group, includes the foreign interest rate, differential interest rates on long term, the international price of oil, misalignments of the nominal exchange rate as well as the expectations kind of charts on the nominal exchange rate; in the second, the differential between the financial intermediation margin observed gaps and their long-term trend and the gap between the Bank intervention rate and the interbank interest rate; the third group was represented by the purchases of foreign currency by the Bank of the Republic; the estimation is made by OLS and the results obtained for all of the variables are significant statistically and quantitatively; also overcome the evidence regarding the normality, autocorrelation, correlation serial, heteroscedasticity, test of Ramsey, test Cusum and Cusum square, test of multicollinearity and Davidson and MacKinnon, proposed in Eviews 9, and that is a variant of the test of Hausman to test the endogeneity. The findings open the possibility for other future research allowing to better scrutinize the actual behavior of a central bank.
