The fundamental role of domestic investment to provide economic prosperity is very well recognized by the economic theory since the Mercantilist theory. Hence, we investigate the impact of domestic investment on economic growth for the case of the Uruguayan economy over the period 1960-2017. For this aim, we employ the Vector Error Correction Model (VECM). Our highlights reveal the absence of a significant impact of domestic investment on growth in the short-and long-run. Due to the marginal role of domestic investment played in the Uruguayan economy, the weak saving rate couldn't significantly help the economy and creating wealth. Therefore, a strong saving policy is required to encourage domestic investors and reevaluate their crucial role in the economic process of Uruguay.

This paper aims to investigate the nexus between domestic investment, exports, imports, and economic growth for the Brazilian economy during the period 1970-2017, using the VECM methodology. In the short-run, our empirical results pointed out that import, exports, and domestic investment cause economic growth. Also, economic growth causes exports. Exports, imports, and economic growth cause domestic investment. However, in the long-run, our results revealed that domestic investment and exports have a positive effect on economic growth. Also, imports have a negative effect on economic growth. The results recorded a positive impact of economic growth and imports on domestic investment. Exports have a negative effect on domestic investment. Finally, we record the absence of significant impact of economic growth, exports and domestic investment on imports, and economic growth, domestic investment, and imports on exports. Due to the importance of these aspects to the economic performance of Brazil, the policymakers are invited to orient these issues towards the sustainability facets to guarantee a sustained growth path.
