Exclusionary Equilibria in Health-Care Markets

We have demonstrated that when providers of health insurance are perceived to be differentiated by consumers, circumstances may arise under which they find it advantageous to restrict the set of health-care providers that they approve to their customers. Even if all health-care providers are equally qualified and efficient, payers may choose to contract with a selected subset of them in order to secure more favorable contract terms. Moreover, in a concentrated health-care market that consists of two health insurance companies (payers) and two health-care providers (hospitals), both payers may choose to contract with only one of the hospitals while excluding the other completely from the market. When consumers' valuation of an extended choice of providers is small in comparison with the extent of differentiation that exists between the payers, such an exclusionary outcome is the unique equilibrium of the game.     

In search of the roots of corporate reputation management: Being a consistent corporate social performer

Corporate social performance (CSP) has received a particularly high share of attention as one of the main determinants of corporate reputation. However, few studies have tested the extent to which the relationship between CSP and corporate reputation may be affected by industry, country, or other context-related variables. Besides, some conceptual thinking suggests that the impact of CSP on corporate reputation may vary according to the level of consistency of a firm's behaviors. However, this view has not been empirically addressed. For this reason, the main objective of this study is to explore the impact of consistency in CSP management on corporate reputation. Specifically, we analyze both the effect of CSP internal consistency (or consistency between environmental and social performance) and CSP consistency over time on corporate reputation. The results based on data from an international sample of 133 companies for the period 2011 to 2016, support either CSP internal consistency or CSP consistency over time (positive increment of CSP over time) positively affecting corporate reputation. The results also confirm the moderation effect of CSP internal consistency on the relationship between CSP and corporate reputation. These results reveal that consistency in social responsibility management helps a firm to consolidate its corporate reputation.
