1. A computerized method of simulating including: electronically receiving data regarding a household representing responses to a questionnaire, the questionnaire covering at least a plurality of positions in stocks and bonds, including identification of industry sectors for the stocks and bonds, if the industry sectors are not automatically identified, a home ownership, including location of the home, and one or more household members' preferences for disposition of the home, and an employment prospect for at least one household member, including identification of an employer, identification of an industry sector for the employer, if the industry sector is not automatically identified, and further including the household member's personal expectations of future job-related earnings and of job stability and the household member's preferences for dates of partial and full retirement; creating a plurality of financial asset objects as data structures from at least some of the received data, the financial asset objects being adapted to represent the positions in stocks and bonds, including risk, return, allowable transaction types, cash flows, and tax treatment; creating at least one home asset object as a data structure from at least some of the received data, the home asset object being adapted to represent the home ownership, including risk, return, the preferences for disposition of the home, cash flows, and tax treatment; creating at least one human capital object as a data structure from at least some of the received data, the human capital object being adapted to represent the employment prospect, including at least milestones for future job-related earnings, partial retirement and full retirement, the industry sector for the household member and the household member's personal expectations job-related earnings and of job stability; modeling in computer readable memory economic interaction among underlying economic factors, the positions, the home ownership and the employment prospect using the financial asset objects, the home asset object and the human capital object, taking into account the industry sector of the household member and the industry sectors of the stocks and bonds, thereby modeling at least risks of unemployment and decreased earnings and coincidence of risks between the positions and the employment prospect; repeatedly running a probabilistic simulation to evaluate performance of the positions, the home ownership and the employment prospect, including applying a plurality of a-priori rules about liquidating the positions in the stocks and bonds, modifying household expenses and drawing down equity in the home ownership, and accounting for tax consequences of income flows resulting from the future job-related earnings and application of the a-priori rules; and reporting at least summary results of the probabilistic simulation.
