This article deals with the impact of intermediaries on insurance market transparency and performance. In a market exhibiting product differentiation and coexistence of perfectly and imperfectly informed consumers, competition among insurers leads to non-existence of a pure-strategy market...

A key feature of insurance markets is that the cost of selling insurance policies is contingent upon not only the number of policies sold but to whom they are sold. This differentiates insurance markets from conventional markets and admits novel strategies, such as segmentation strategies,...

Classical oligopoly models predict that firms differentiate vertically as a way of softening price competition, but some metrics suggest very little quality differentiation in the U.S. auto insurance market. I explain this phenomenon using the fact that risk-averse insurance companies with...

This paper looks at markets characterized by the fact that the demand side is insured. In these markets a consumer purchases a good to compensate consequences of unfavorable events, such as an accident or an illness. Insurance policies in most lines of insurance base indemnity on the insured's...

This paper locks at markets charaterized by the fact that the demand side is insured. In these markets a consumer purchases a good to compensate consequences of unfavorable events, such as an accident or an illness. Insurance policies in most lines of insurance base indemnity on the insured's...

This paper analyses the concentration in the insurance sector and the impact of the market structure (distribution of market shares) and the number of insurance companies on the level of concentration (and competition) in the insurance sector in Serbia (excluding Kosovo and Metohija) in the...

This paper reviews the Hotelling literature of product differentiation. The purpose of this work is to examine the impact of the market structure on price competitionand equilibrium differentiation. The existence of a general ’principle of differentiation’ is rejected. In contrast,...

In his book on 'Market Microstructure' Spulber presented some strange results with respect to the impact of the substitutability parameter in an intermediation model with differentiated products and inputs. Intuitively, effects in the product and the input market should be similar: if firms...

In this paper, I compare two-part tariff competition to linear pricing in a vertically differentiated duopoly. Consumers have identical tastes for quality but differ in their preferences for quantity. The main finding is that quality differentiation occurs in equilibrium if and only if two-part...
