This paper considers a dynamic model of the evolution of open source software projects, focusing on the evolution of quality, contributing programmers, and users who contribute customer support to other users. Programmers who have used open source software are motivated by reciprocal altruism to...

Pay-what-you-want schemes can be a useful tool to finance high quality and independent news media without restricting readership, therefore guaranteeing maximum diffusion. We conduct a field experiment with the Italian information site lavoce.info to explore how to structure a campaign in a way...

This paper provides first firm-level evidence of the links between income inequality and the patterns of trade and export prices. We identify a theoretical mechanism behind these links, which suggests that a more unequal income distribution leads to higher average prices. We test the theory...

This paper examines the relationship between the credit constraints faced by a firm and the unit value prices of its exports. The paper modifies Arkolakisś (2010) model of trade with heterogeneous firms by introducing endogenous quality and credit constraints. The model predicts that tighter...

A monopolist producing vertically differentiated durable goods can offer in each period a sequence of price-quality menus to segment the market. We show that, contrary to the Coase conjecture for the homogeneous durable good monopoly, thanks to the ability to produce differentiated durable...

This paper analyzes the generalized quality differentiation model in multi-sided markets with positive externalities, which leads to new insights into the optimal pricing structure of the firm. We find that quality differentiation for users on one side affects not only the side involving...

A durable good monopolist faces a continuum of heterogeneous customers who make purchase decisions by comparing present and expected price-quality offers. The monopolist designs a sequence of price-quality menus to segment the market. We consider the Markov Perfect Equilibrium (MPE) of a game...

This paper uncovers new stylized facts on the relation between economic integration and world trade prices. Using export price data combined with data on 32 WTO (World Trade Organization) accessions by developing countries and hundreds of new PTAs (Preferential Trade Agreements), we show that a...

We investigate theoretically and empirically how exporters adjust their markups across destinations depending on bilateral distance, tariffs, and the quality of their exports. Under the assumption that trade costs are both ad valorem and per unit, our model predicts that markups rise with...
