it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
the main logic behind the demand for life insurance is to hedge against the labor income uncertainty due to premature death of a wage earner. in other words, life insurance is the device by which this labor income uncertainty is handled. for insurers, the uncertainty arises from the lack of knowledge about the age of death of the wage earner. this paper attempts to derive life insurance demand ...
Since optimal investment strategies generally cannot be obtained in closed form when utility functions exhibit non-constant risk aversion, most dynamic investment studies have focused on the constant risk aversion case. The present paper investigates a general class of dynamic investment models with fmal-period expected wealth objective for which the fmal-period utility of wealth function is no...
In this paper, we try to develop and modify the basic model of the consumption-based capital asset pricing model by adding the growth in real money balances rate as a risk factor in the household's utility function as (M-CCAPM). For this purpose, two forms of utility function with constant relative risk aversion (CRRA) preferences and recursive preferences have been used such that M1 and M2 are...
Most frequently used class of utility functions for modelling the investment policy of individual agents by the constant relative risk aversion (CRRA) utility functions. The objective of this paper is to try to provide the plausible risk aversion parameter of individual households under this assumption. I argue that the risk aversion of an individual investor may be significantly larger than is...
The important defect of the previous models , is assumed that consumer behavior is based on logic and with a rise in the price their consumption decreased and they accurately have no problems with their control. However, various parameters such as lifestyle, habits and emotions and something like that can be effective. In this paper, we use the new model called the OLG model and the CRRA funct...
We focus on automatic strategies to optimize life cycle savings and investment. Classical optimal savings theory establishes that, given the level of risk aversion, a saver would keep the same relative amount invested in risky assets at any given time. We show that, when optimizing lifecycle investment, performance and risk assessment have to take into account the investor's risk aversion and t...
