We develop a model of competition in the solar panel industry. Solar firms manufacture panels that are differentiated both vertically and horizontally, and compete by setting quantities. The equilibrium of the model is consistent with a set of stylized facts that we document, including variation...

The price of solar panels has fallen rapidly over the last few decades. Using an extensive dataset of prices, costs, output, sales and technical characteristics of firms in the solar industry during 2005-2011, this paper investigates the factors that have contributed to the decline in costs and...

The impact of input price changes on industry concentration in a Cournot oligopoly depends on the type of firm heterogeneity and on the curvature of the demand function. Firms might be heterogeneous in their ability to use the input undergoing the price change, or in their ability to use...

This paper develops a model of technological progress in the microprocessor industry that connects the seemingly disparate engineering and economic measures of technological progress. Technological progress in the microprocessor industry is driven by the repeated adoption of higher quality...
