Firms frequently advertise products and services before they are launched. Yet how to best design such advertisements is not well understood. The current article investigates how consumers respond to uncertainty in prerelease advertisements. Across five studies, including both field and lab studies, we first provide evidence for the positive effect of uncertain prerelease advertisements using real consumer behavior on Facebook and YouTube and at the box office. Next, we uncover the mechanism underlying this effect (i.e., inflated outcome expectancies), outline a managerially relevant boundary condition (i.e., the positive effect reverses when a preorder opportunity is offered), and demonstrate that the effect of uncertainty on consumer response differs in prerelease versus postrelease advertisements depending on consumers’ perceived risk. Finally, we discuss implications for marketing research as well as for the design of prerelease advertisements for stimulating prerelease buzz and word of mouth. 相似文献

We use a nonlinear commodity market model to assess, theoretically and empirically, the impacts of recent reforms of the CAP on prices and economic welfare in the EU. The empirical analysis is based on an aggregate structural econometric model of the EU wheat economy and its links to the rest of the world. Instability issues are also investigated. Impacts of CAP reforms on the variance of domestic and world prices are analysed and a Monte Carlo simulation is used to evaluate uncertainty in the model's welfare computations. Recent reforms led to a net welfare gain within the EU during the period 1993–2000. Additional budgetary costs are less than the welfare gains of consumers and producers. Producers gained as lower price support was overcompensated by additional direct payments. 相似文献

Abstract. I evaluate a new German regulation that requires retail discounters to guarantee the availability of their products in bargain sales. The regulation is meant to prevent loss leaders. Retailers undermine the regulation's rationale by claiming that rationing is due to demand uncertainty. This paper shows that under demand uncertainty the regulation has ambiguous welfare effects. Effectively, it raises production, which, under imperfect competition, tends to be beneficial. However, the regulation overshoots and decreases welfare if it requires availability for a state of high demand that is relatively unlikely. In this case more sophisticated regulation is required. 相似文献

This paper shows that, contrary to what is generally believed, decreasing concavity of the agent's utility function with respect to the screening variable is not sufficient to ensure that stochastic mechanisms are suboptimal. The paper demonstrates, however, that they are suboptimal whenever the optimal deterministic mechanism exhibits no bunching. This is the case for most applications of the theory and therefore validates the literature's usual focus on deterministic mechanisms. 相似文献

Social influences on self-control underlie both self-help groups and many peer interactions among youths. To understand these phenomena, we analyze how observing each other's behavior affects individuals’ ability to deal with their own impulses. These endogenous informational spillovers lead to either a unique “good news” equilibrium that ameliorates behavior, a unique “bad news equilibrium” that worsens it, or to the coexistence of both. A welfare analysis shows that people will find social interactions valuable only when they have enough confidence in their own and others’ ability to resist temptation. The ideal partner, however, is someone with a slightly worse self-control problem than one's own: this makes his successes more encouraging, and his failures less discouraging. 相似文献

The purpose of this study is to examine the influence of the announcement of a new airport hub on housing prices near the
airport. While numerous studies of airport noise have found that high noise levels reduce property values, few have been able
to measure the announcement effect on values. The results indicate that after controlling to extraneous influences, housing
property prices in a 2.5 mile band from the Greensboro/High Point/Winston Salem metropolitan airport declined approximately
9.2% in the post-announcement period. In the next 1.5-mile band, house prices declined approximately 5.7% in the post-announcement
period. 相似文献
