decisionSupport package supports the quantitative analysis of
welfare based decision making processes using Monte Carlo simulations. This
is an important part of the Applied Information Economics (AIE) approach
developed in Hubbard (2014). These decision making processes can be
categorized into two levels of decision making:
The actual problem of interest of a policy maker which we call the underlying welfare based decision on how to influence an ecological-economic system based on a particular information on the system available to the decision maker and
the meta decision on how to allocate resources to reduce the uncertainty in the underlying decision problem, i.e to increase the current information to improve the underlying decision making process.
The first problem, i.e. the underlying problem, is the problem of choosing the decision which maximizes expected welfare. The welfare function can be interpreted as a von Neumann-Morgenstern utility function. Whereas, the second problem, i.e. the meta decision problem, is dealt with using the Value of Information Analysis (VIA). Value of Information Analysis seeks to assign a value to a certain reduction in uncertainty or, equivalently, increase in information. Uncertainty is dealt with in a probabilistic manner. Probabilities are transformed via Monte Carlo simulations.
The functionality of this package is subdivided into three main parts: (i) the welfare based analysis of the underlying decision, (ii) the meta decision of reducing uncertainty and (iii) the Monte Carlo simulation for the transformation of probabilities and calculation of expectation values. Furthermore, there is a wrapper function around these three parts which aims at providing an easy-to-use interface.
The meta decision of how to allocate resources for uncertainty reduction can be analyzed with this package in two different ways: via (i) Expected Value of Information Analysis or (ii) via Partial Least Squares (PLS) analysis and Variable Importance in Projection (VIP).
decisionSupport integrates the most important features of this
package into a single function. It is wrapped arround the functions
