When income growth under price dispersion reduces the time of search and raises prices of purchases, the increase in purchase price can be presented as the increase in the willingness to pay for insurance or the willingness to pay for consumer credit. The optimal consumer decision represents the...

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...

When expected savings on purchases are greater than the wage rate, the optimal search results in the negative marginal utility of leisure. The search transforms the classical backward bending effect and the leisure becomes complementary to the search. Consumers compensate “bad” leisure by...

The analysis of the propensity to search specifies the “common” or the ordinary model of consumer behavior based on the synthesis of the neoclassical approach with satisficing concept and “leisure” and “labor” models of behavior that represent different combinations of conspicuous...

The development of G.Stigler’s original model of search describes the mathematical relationship between the elasticity of the marginal utility of consumption, the price elasticity, and the elasticity of the marginal utility of money income with respect to increase in the price of living and/or...

When the increase in income reduces the time of search and increases prices of purchases, the increase in price can be presented as the increase in the willingness to pay for insurance. The optimal consumer decision represents the trade-off between the propensity to search for proficient...
