The measurement uncertainty budget is determined once and remains constant. With a constant measurement uncertainty budget, complete data records can now be acquired. The measurement uncertainty applies to every single measurement point. If the measurement uncertainty is constant, this simplifies the further processing based on the data records.
An econometric model specifies the statistical relationship that is believed to hold between the various economic quantities pertaining to a particular economic phenomenon. An econometric model can be derived from a deterministic economic model by allowing for uncertainty, or from an economic model which itself is stochastic. However, it is ...
For example, in public finance the Robinson Crusoe economy is used to study the various types of public goods and certain aspects of collective benefits. [2] It is used in growth economics to develop growth models for underdeveloped or developing countries to embark upon a steady growth path using techniques of savings and investment.
The budget set is bounded above by a -dimensional budget hyperplane characterized by the equation =, which in the two-good case corresponds to the budget line. Graphically, the budget set is the subset of R + k {\displaystyle \mathbb {R} _{+}^{k}} that contains all the consumption bundles that lie on or below the budget hyperplane.
Robert Hall was the first to derive the effects of rational expectations for consumption. His theory states that if Milton Friedman’s permanent income hypothesis is correct, which in short says current income should be viewed as the sum of permanent income and transitory income and that consumption depends primarily on permanent income, and if consumers have rational expectations, then any ...
In macroeconomics, the guns versus butter model is an example of a simple production–possibility frontier. It demonstrates the relationship between a nation's investment in defense and civilian goods. The "guns or butter" model is used generally as a simplification of national spending as a part of GDP. This may be seen as an analogy for ...
Economic profit does not indicate whether or not a business decision will make money. It signifies if it is prudent to undertake a specific decision against the opportunity of undertaking a different decision. As shown in the simplified example in the image, choosing to start a business would provide $10,000 in terms of accounting profits.
This can be done in a period of recession or economic uncertainty, when unemployment of labor is high and other resources are underutilized. Increased spending by government increases the rate of aggregate demand, increasing business activity, which increases income, which further increases spending and aggregate demand, in a virtuous cycle.
