This paper investigates the merger wave hypothesis for the US and the UK employing a Markov regime-switching model. Using quarterly data covering the last 30 years, for the US, we identify the beginning of a merger wave in the mid 1990s but not the much-discussed 1980s merger wave. We argue that the latter finding can be ascribed to the refined methods of inference offered by the Gibbs sampling approach. As opposed to the US, mergers in the UK exhibit multiple waves, with activity surging in the early 1970s and the late 1980s.

This article studies how organizations should design a product by choosing the carbon footprint and price in a market with climate concerns. The authors first show how the cost and demand effects of reducing the product carbon footprint determine the profit-maximizing design. Paradoxically, they find that stronger climate concerns may increase the overall corporate carbon footprint, even if the product itself is greener. Next, the authors establish that offsetting carbon emissions can create a win-win outcome for the firm and the climate if the cost of compensation is sufficiently low. Third, the authors show how regulation in the form of a cap-and-trade scheme or a carbon tax affects product design, firm profitability, and green technology adoption. Finally, the authors extend the analysis to a competitive scenario. Overall, these results can help marketing professionals by offering insight into how to address climate concerns through improved product design.

Abstract:We analyze the factors that influence the support for environmental policy proposals. Swiss referendum data show that proposals obtain more yes-votes if they do not restrict consumption possibilities directly, if they are endorsed by business associations, if environmental preferences are strong and economic conditions are favorable at the time of the referendum. Also, there are more pro-environmental votes in cantons with higher population density. On the other hand, yes-votes do not seem to depend on whether a proposal involves a tax or not.Keywords: Environmental Policy, Direct Democracy, Referendum, Public Choice JEL Classification: P16, Q28---------------------*Corresponding author: University of Zürich, Socioeconomic Institute, We are grateful to Zava Aydemir, Dennis Gärtner, Markus König, Hansjörg Lehmann, Severin Pflüger, Andreas Polk, Harald Telser and Peter Zweifel for helpful comments and suggestions.

Are initial competitive advantages self-reinforcing, so that markets exhibit an endogenous tendency to be dominated by only a few firms? Although this question is of great economic importance, no systematic empirical study has yet addressed it. Therefore, we examine experimentally whether firms with an initial cost advantage are more likely to invest in marginal cost reductions than firms with higher initial costs. We find that the initial competitive advantages are indeed self-reinforcing, but subjects in the role of firms overinvest relative to the Nash equilibrium. However, the pattern of overinvestment even strengthens the tendency towards self-reinforcing cost advantages relative to the theoretical prediction. Further, as predicted by the Nash equilibrium, mean-preserving spreads of the initial cost distribution have no effects on aggregate investments. Finally, investment spillovers reduce investment, and investment is higher than the joint-profit maximizing benchmark for the case without spillovers and lower for the case with spillovers.
