Much of today’s software relies on programming code shared openly online. Yet, it is unclear why volunteer developers contribute to open-source software (OSS), a public good. We study OSS contributions of some 22,900 developers worldwide on the largest online code repository platform, GitHub,...

A theoretical model is adopted in order to examine optimal fare and optimal quality of supply schemes for a transport operator. The analysis shows how fares and quality of supply are related to travel distance and to the transport operator's weight on profit versus consumer surplus. Under...

This paper derives a three stage Cournotoligopoly game for product innovation, expenditure on introducing the product and competition on the product market. Product innovation is assumed to increase consumer utility but is effective only if the innovating firm invests in marketing, so that...

In health markets, government policies tend to subsidize poorer groups. The purpose of this paper is to analyze the implications of an income-based subsidy policy on the incentives of countries to implement price arbitrage and of firms to provide market access to poorer groups. --...

We present a policy game where a Rich country has a higher capacity than a Poor country to commit to certain elements of health policy such as providing income related price subsidies and allowing parallel imports (PI). When allowing PI is not a choice for the Poor country, the Rich country...

We study the impact a redistribution of income has on the decisions of a health care innovator and the utility of consumers. We find that income redistribution from rich to poor increases the quality of the medical innovation, reduces its price and increases the utility of some of the consumers...

Governments often subsidize poorer groups in society to ensure their access to new drugs. We analyze here the optimal income-based price subsidies in a strategic environment. We show that asymmetric health systems can arise even though countries are ex-ante symmetric when international price...

We examine the relation between consumer search and equilibrium prices when collusion is endogenously determined. We develop a theoretical model and show that average price is a U-shaped function of the measure of searchers: prices are highest when there are no searchers (local monopoly power)...

In this study, we analyze the incentives of a streaming platform to bias consumption when products are vertically differentiated. The platform offers mixed bundles of content to monetize consumer interest in variety and pays royalties to sellers based on the effective consumption of the...

We study the incentives of a streaming platform to bias consumption when products are vertically differentiated. The platform offers mixed bundles of content to monetize consumers' interest in variety and pays royalties to sellers based on the effective consumption of the content they produce....
