Enhancing the economy growth of Puerto Rico Calculating the amount of fixed investment needed to boost economic growth Prepared by José I Alameda Lozada Ph.D. Economist and Professor at the UPR, Mayaguez
Main nominal GNP’s components GNP = Gross National Product, C = Personal Consumption G = Government Expenditures I = Gross Domestic Investment X= Sales to the rest of the world or Exports M = Purchases from the rest of the world or Imports GNP = C + G + I + (X –M)
Puerto Rico’s GNP Components, nominal prices
Main assumption of the model Re-grouping the components: GNP = (C + G) + (X –M) + I Fixed average growth rate Fixed amount Target Variable growth rate
Main assumptions to forecast GNP Assumptions under this model: Inflation rate = 2% Fixed average growth rate Fixed amount
Investment Requirement to enhance economic growth Target variable = Gross Fixed Investment I = Change inventories + Gross Fixed Investment Changes inventories is assumed at 260 millions during Gross Fixed Investment is the target. It means construction of tangible plant building, machinery and equipment, and infrastructure.

Then, local authorities need to re- focus the source of investment or diversify countries portfolio.
