Time series constitute a statistical and econometric tool of high relevance for measuring, analyzing, and projecting economic processes in territories with particular structural characteristics, such as Puerto Rico. However, the academic literature applying these models specifically to the Puerto Rican case remains scarce and scattered, and seldom connects findings from official sources and quasi-experimental research with the formal apparatus of classical time series models. In response to that gap, this article critically examines the state of the art of ARIMA, VAR, cointegration, and ARCH/GARCH models applied to Puerto Rican macroeconomic indicators, as well as their complementarity with contemporary machine learning approaches. A narrative review of the specialized literature and official technical reports published between 1970 and 2026 was conducted, organized around three specific objectives: systematizing the theoretical foundations of the models, identifying the state of the art applied to the Puerto Rican context, and formulating a future research agenda. The results show that available studies on economic activity, public debt, and hurricane impacts in Puerto Rico document severe structural breaks and persistent economic effects, while recent methodological evidence suggests that hybrid models combining classical econometrics and machine learning improve predictive capacity in the face of exogenous shocks. The article concludes that strengthening the Puerto Rican empirical base in this field requires greater availability of high-frequency data, systematic incorporation of intervention variables, and a research agenda that combines non-conventional administrative data sources with Bayesian and deep learning models.
