We extend the comparison of experiments in Blackwell (1953) to a strategic setting that both simplifies and expands upon ideas in Gossner (2000). We introduce a partial order on correlating signals, called more strategically informative, and prove that it is equivalent to the partial order more...

We consider a two-period LEN-type agency problem. The principal needs to implement one out of two accounting systems. One emphasizes relevance, the other reliability. Both systems produce identical inter-temporally correlated signals. The relevant system reports an accounting signal in the...

What are the welfare effects of the information contained in macroeconomic statistics, central-bank communications, or news in the media? We address this question in a business-cycle framework that nests the neoclassical core of modern DSGE models. Earlier lessons that were based on “beauty...

We consider two vertical links between informal- and formal-sector firms and study their implications. In one case, the final products produced by the formal- and informal-sector firms are vertically differentiated in terms of quality, and the size of the informal sector demand is related to the...

This paper studies how the arrival of information affects welfare in a general equilibrium exchange economy with incomplete and differential information. It considers a setup in which agents differ in their attitudes toward risk. This introduces gains from trade. In equilibrium, the information...

We study a dynamic information design problem in a finite-horizon setting consisting of two strategic and long-term optimizing agents, namely a principal (he) and a detector (she). The principal observes the evolution of a Markov chain that has two states, one "good" and one "bad" absorbing...

Using the introduction of high-speed rail (HSR) as an exogenous shock to costs of information acquisition, we show that reductions in information-acquisition costs lead to (i) a significant increase in information production, evidenced by a higher frequency of analysts visiting portfolio firms,...
