We study the long-run market configurations in a quality-ladder dynamic model. Specifically, we assume that the return to investment in quality differs across the firms. That is, for a given level of investment, one firm has a higher probability to raise the quality of the good it produces. We...

We investigate the short- and long-term effects of different types of R&D collaborations on firms, consumers, and the industry. To that end, we consider a differentiated-product market in which firms compete a la Bertrand and invest in process innovation in order to lower the production cost...

We study the impact of standard-setting by introducing an externality that increases product compatibility in the presence of asymmetric returns to investment in a dynamic quality-ladder-type model. We classify the long-run, multi-modal probability distributions over different market structures...

In an effort to lower costs of provision, authorities have encouraged the consolidation of providers for a number of services such as electricity distributors, school boards, hospitals, and municipalities. In this paper we propose an endogenous merger process to evaluate the impact of...

A key problem with solar energy is intermittency: solar generators only produce when the sun is shining. This adds to social costs and also requires electricity system operators to reoptimize key decisions with large-scale renewables. We develop a method to quantify the economic value of...

This paper develops a decision making empirical method to evaluate welfare programs accounting for heterogeneity of impacts. We find outcome predictive distributions for different subgroups of the population and use a characterization of second order stochastic dominance to give a policy...

The expansion of the share of renewable energy in the portfolio mix of the electricity generation sector has accelerated the development and integration of large-scale battery storage facilities. We document charging and discharging patterns in the California market and show how battery activity...

Using a novel dataset from a large supermarket retailer in a European country that never engages in temporary sales, we establish that prices are actually as sticky as regular prices. Circumventing the debate on whether sales have to be included or excluded from price adjustments, we find...
