In order to measure a country's production efficiency, let ( Xin {mathrm{Re}}_^p ) and ( Yin {mathrm{Re}}_^q ) be the input and output vectors, representing total labor force and capital stock the inputs and GDP the outputs.
However, for the countries in this analysis, the difference in inputs (ports and GDP) is quite fixed and thus important.
We consider two inputs (primary energy consumption and population) and two outputs (CO2 and GDP), including a fixed input factor (viz. population).
The same two variables (number of large SSS ports and GDP per head (Fig. 2)) were used as inputs for the DEA, while the output in the DEA is made up of the total SSS volume.
Second, medical and especially non-medical inputs to the production of health are not very well captured by HCE and GDP and alcohol consumption per capita, respectively.
In the absence of special "health R&D exchange rates" based on the comparative costs of the inputs into the activity, the two conversion rates most readily available are current exchange rates and GDP purchasing power parities (PPPs).
The big impact of inventories is something of a red flag, particularly since the consumer input to GDP was weaker in the fourth quarter than in the prior period, and Dan Egan, president of the Massachusetts Credit Union League, expects the Feb. 26 updated look from the Commerce Department to rein in the estimate.
All this could harm trade and GDP.
It also allows you to input your own long-term assumptions to project the likely path of debt to 2020.There are two things that matter in government-debt dynamics: the difference between real interest rates and GDP growth (r-g), and the primary budget balance as a % of GDP (ie, before interest payments).
This input variable (GDP) in the uncertainty assessment becomes the dependent variable on these influences.
