oligopoly
an oligopoly is a market structure in which a market or industry is dominated by a small number of firms (oligopolists). oligopolies can create the incentive for firms to engage in collusion and form cartels that reduce competition leading to higher prices for consumers and less overall market output. alternatively, oligopolies can be fiercely competitive and engage in flamboyant advertising campaigns.

many employers offer wellness or health promotion programs to help employees improve their health and avoid unhealthy behaviors. both small and large firms offer a program in at least one of these areas: smoking cessation; weight management; behavioral or lifestyle coaching. 46% of small firms and 83% of large firms offer these. 3% percent of small firms and 16% of large firms reported collecting health information from employees through wearable devices like  a fitbit or apple watch. 42% of large firms with one of these health and wellness programs offered employees a financial incentive to participate in or complete the program. among most large  firms with an incentive for completing wellness programs, incentives include: lower premium contributions or cost sharing (34% of firms); cash, contributions to health-related savings accounts, or merchandise (76% of firms); some other type of incentive (14% of firms). some firms separate financial incentives for different programs and some others have incentives that require participation in more than one type of program (e.g., completing an assessment and participating in a health promotion activity).
