Perez-Sebastian, F. ; Raveh, O. The Natural Resource Curse and Fiscal Decentralization. American Journal of Agricultural Economicsajae 2015, 98, 212 - 230. Publisher's VersionAbstract
Natural resource abundance is a blessing for some countries, but a curse for others. We show that differences across countries in the degree of fiscal decentralization can contribute to this divergent outcome. Using a large panel of countries covering several decades and various fiscal decentralization and natural resource measures, we provide empirical support for the novel hypothesis. We also study a model that combines political and market mechanisms under a unified framework to illustrate how natural resource booms may create negative effects in fiscally decentralized nations.
Golan, H. ; Ert, E. Pricing decisions from experience: The roles of information-acquisition and response modes. Cognition 2015, 136, 9 - 13. Publisher's VersionAbstract
While pricing decisions that are based on experience are quite common, e.g., setting a selling price for a used car, this type of decision has been surprisingly overlooked in psychology and decision research. Previous studies have focused on either choice decisions from experience, or pricing decisions from description. Those studies revealed that pricing involves cognitive mechanisms other than choice, while experience-based decisions involve mechanisms that differ from description-based ones. Thus, the mutual effect of pricing and experience on decision-making remains unclear. To test this effect, we experimentally compared real-money pricing decisions from experience with those from description, and with choices from experience. The results show that the mode of acquiring information affects pricing: the tendency to underprice high-probability prospects and overprice low-probability ones is diminished when pricing is based on experience rather than description. The findings further reveal attenuation of the tendency to underweight rare events, which underlies choices from experience, in pricing decisions from experience. The difference occurs because the response mode affects the search effort and decision strategy in decisions from experience.
Genesove, D. ; Simhon, A. Seasonality and the Effect of Advertising on Price. The Journal of Industrial Economics 2015, 63, 199-222. Publisher's VersionAbstract
Does advertising make markets more or less competitive? This paper lays out an econometric strategy for estimating the effect of advertising on prices that exploits seasonal demand and imperfect targeting of consumers. We find mostly negligible effects of advertising on prices at monthly frequency: among the 35 (of 131) product categories with sufficient advertising seasonality to justify second-stage estimation, only nine have a significant effect, and those are typically small. This finding is essentially the result of the much greater seasonality in advertising than price.
