If the demand under price dispersion is formed by consumers with zero search costs and consumers with positive search costs, the law of one price holds at the equilibrium price level, where the lowest willingness to pay between consumers with zero search costs meets the willingness to accept or...

The theory of the optimal-consumption leisure choice under price dispersion describes the phenomenon of moral hazard as the customer's reaction on unfair insurance policy. The unfair insurance offer does not equalize marginal costs of propensity to seek healthcare with marginal benefits on...

The analysis of the propensity to search under price dispersion discovers the identity of the optimal consumption-leisure choices in the model of optimal search and in the classical model of individual labor supply when the propensity to search is unimportant. However, the vigorous propensity to...

One of the applications of the prospect theory is the behavioral phenomenon of the negative elasticity of the individual labor supply. This paper argues that the negative elasticity of labor supply can be understood better with the help of the interpretation of the Slutsky equation with regard...

The paper describes the microeconomic trade-off between prices, savings on purchases, and the time horizon of the consumption-leisure choice during the search for different products. When marginal costs of the search are equal to its marginal benefit, the time of search is proportional to...

The paper argues that when a consumer searches for a lower price, a satisficing decision procedure equalizes marginal costs of search with its marginal benefit. The consumer can maximize the utility of his consumption-leisure choice with regard to the equality of marginal values of search....

The paper argues that sunk costs’ sensitivity can lead to the optimal consumption-leisure choice under price dispersion. The increase in quantity to be purchased with the extension of the time horizon of the consumption-leisure choice equalizes marginal costs of search with its marginal...

The paper discovers microeconomic mechanism of Veblen effect as well as of Giffen case as results of the negative marginal utility of money. The marginal utility of consumption also becomes negative. The total consumption-leisure utility is increased due to the increase in leisure time. This...

The synthesis of the G.Sigler’s rule of the optimal search with the classical individual labor supply model enlarges the understanding of the phenomenon of money flexibility. The constraints of the search model makes the Lagrangian multiplier equal to the marginal utility of the wage rate and...
