Metodología: Especificamos un modelo VAR restringido derivado de un modelo teórico de la relación entre las economías de Puerto Rico y Estados Unidos.  Resultados: Los resultados apuntan a que los aumentos en las tasas de interés de Estados Unidos pueden explicar una variación considerable del desempleo en Puerto Rico, mas no así de la inflación.  Limitaciones: No se toman en cuenta posibles efectos no lineales.  Originalidad: Se especifica un nuevo modelo VAR novel, diferenciándose de otros modelos por su matriz con restricciones que describen la relación unidireccional entre las economías de Estados Unidos y Puerto Rico, inclusión de tasas de interés a distintas maduraciones y variables principales que determinan las decisiones sobre la tasa de interés para estudiar el impacto de políticas monetarias de Estados Unidos sobre economías dolarizadas.  Conclusiones: Es importante considerar la relación entre las economías dolarizadas y la de Estados Unidos incorporando restricciones que describan la misma, las variables que afectan las decisiones del banco central y las expectativas, así como la importancia de explorar políticas complementarias para mitigar efectos negativos sobre el mercado laboral.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Objective: Develop an econometric model to estimate the impact of U.S. monetary policy on small and dollarized economies, considering the main variables influencing the decisions of the U.S. central bank, and apply this model to the case of Puerto Rico.  Methodology: We specify a restricted VAR model, derived from a theoretical model of the relationship between the U.S and Puerto Rico economies.  Results: Results show that interest rate increases can explain a considerable variation in Puerto Rico unemployment, but not in inflation.  Limitations: Non-linear effects are not accounted for.  Originality: A novel VAR model is specified, distinguishing itself from other models by its matrix of restrictions that describe the unidirectional relationship between the economies of the United States and Puerto Rico, the inclusion of interest rates at different maturities, and key variables that determine interest rate decisions to study the impact of U.S. monetary policies on dollarized economies.  Conclusions: It is important to consider the relationship between dollarized economies and U.S. economy, incorporating constraints that describe it, as well as the variables affecting central bank decisions and expectations, as well as to explore complementary policies to mitigate the negative effects of tightening monetary policy on the labor market.]]></p></abstract>
