This paper analyzes the effects of network positions and individual risk attitudes on individuals' strategic decisions in an experiment where actions are strategic substitutes. The game theoretic basis for our experiment is the model of Bramoullé and Kranton (2007). In particular, we are interested in disentangling the influence of global, local and individual factors. We study subjects' strategic investment decisions in four basic network structures. As predicted, we find that global factors, such as the regularity of the network structure, influence behavior. However, we also find evidence that individual play in networks is to some extent boundedly rational, in the sense that coordination is influenced by local and individual factors, such as the number of (direct) neighbors, local clustering and individuals' risk attitudes.
Abstract:Do potential entrepreneurs exploit welfare-destroying opportunities as much as they exploit welfare-enhancing opportunities as it is assumed in several normative models? Do we need to prevent potential entrepreneurs from being destructive or are there intrinsic limits to harm others? We experimentally investigate how people with different entrepreneurial intent exploit risky investment opportunities that are associated with negative and positive externalities. We find that participants who consider entrepreneurship as a future occupation invest significantly less than others in destructive opportunities. Nevertheless, our results support prior evidence that the entrepreneurially talented invest more in destructive opportunities. The latter effect seems to be entrepreneurship-specific, because the investment behavior of the generally more talented does not differ from that of other participants. Taken together, our results suggest that people who are willing to exploit destructive opportunities do not only do this in private ventures, but also -and maybe even more so -in wage employment. Highlights:We examine correlations between entrepreneurial attitudes, investment with externalities and other-regarding behavior. We consider investments causing positive, negative, and no externalities. Entrepreneurial self-efficacy correlates with more investment in general. Entrepreneurial intent correlates with less investment for negative externalities.

We modify the standard model by the assumption that the bidders have reference-based utility, where a publicly announced reserve price has some influence on the reference point. It turns out that the seller's optimal reserve price is increasing in the number of bidders. Also in contrast to the standard model, we find that secret reserve prices can outperform public reserve prices, and that setting the optimal reserve price can be more valuable for the seller than attracting additional bidders.
We use an asset market model based on Diamond (1985) to demonstrate that increased central bank transparency may lead to crowding out of costly private information, which can result in a market that is less able to predict monetary policy. Consequently, for intermediate levels of public information precision, it is optimal for the central bank to actually disclose less than it knows. We show that such crowding out can occur, even in the likely scenario that public information is more precise than private information, under the plausible assumption that traders are nearly risk neutral. Central banks should be aware of possible adverse effects of transparency and take note if market participants reduce investment in information.JEL codes: E43, E52, G14 Keywords: monetary policy, communication, transparency, information and financial market efficiency, information acquisition. BERNANKE (2004) STATES THAT "clear communication helps to increase the near-term predictability of [central bank] rate decisions, which reduces risk and volatility in financial markets and allows for smoother adjustment of the economy to rate changes." This statement is generally supported by empirical research on the impact of communication on the predictability of monetary policy. We, however, tell a cautionary tale of the potential adverse effects of central bank communication. We follow Diamond (1985) and use a rational expectations asset market model with a public signal and costly private information acquisition. An increasingly precise public signal is found to improve predictability only as long as it
