We derive equilibrium incentives to use comparative advertising that pushes up own brand perception and pulls down the brand image of targeted rivals. Data on content and spending for all TV advertisements in Over‐The‐ Counter (OTC) analgesics enable us to construct matrices of rival targeting expenditures and estimate the structural model. Using brands' optimal choices, these attack matrices identify diversion ratios, from which we derive comparative advertising damage measures. We find that comparative advertising causes more damage to the targeted rival than benefit to the advertiser. We simulate banning comparative advertising to find industry profits rise.  相似文献

This article investigates the costs of transport regulation using the example of agricultural markets in the US. Using a large database of prices by state of agricultural commodities, we find that dispersion fell for many commodities until the First World War. We demonstrate that this reflected changes in transport costs which in turn in the long run depended on productivity growth in railroads. The year 1920 marked a change in this relationship, however, and between the First and Second World Wars we find considerable disintegration of agricultural markets, ultimately as a consequence of the 1920 Transportation Act. We argue that this benefited railroad companies in the 1920s and workers in the 1930s, and we put forward an estimate of the welfare losses for the consumers of railroad services (that is, agricultural producers and final consumers).  相似文献

There is a surprisingly high number of new products and services that fail to produce enough return on the firm's investments in development and launch activities. Literature has shown that these failures can be due to a poorly planned and executed launch. Although a vast stream of research has studied how strategic and tactical launch decisions affect the performance of new products and services, some issues still need theoretical and empirical investigation. This paper aims to extend new product launch research in two ways. First, it studies how tactical launch decisions (i.e., investments in advertising and involvement of external organizations in the launch process) interact with an important strategic choice (i.e., the degree of radicalness of the new product or service) to affect new product performance. Second, it focuses on a particular dimension of performance, that is, early market survival, which has been overlooked in launch strategy and tactics research so far. Using a data set comprising more than 9300 new mobile value‐added services launched in Italy between 2003 and 2006, the paper finds that launch tactics interact with the radicalness of the innovation to affect early market survival. In particular, communicating the distinctive characteristics of the new product or service and partnering with external organizations during the launch process are tactics that work particularly well with radical innovations. This is possibly due to the fact that they help reduce customers’ uncertainty regarding expected benefits and transaction costs, and hence contribute to win their resistance to adopt the innovation soon after launch. Investments in corporate advertising lead instead to a tangible improvement of the probability of early market survival for both radical and incremental innovations. In other words, the positive impact on the probability of early survival of increasing investments in corporate advertising appears to be relevant for both radically and incrementally new services. One possible explanation is that this tactic helps increase the number of potential customers who come to know about the existence of the innovating firms and its offering soon after launch, but this is likely to be equally important to stimulate early diffusion of both incremental and radical innovations.  相似文献

Should voters always pay attention to politics? I explore the role of endogenous costly attention allocation in politics, combining insights from the growing literature on rational inattention with a standard model of political agency. I show that when attention to the action of the politician is endogenous, voters may choose to pay too much attention in equilibrium, and this induces too much political pandering. Moreover when attention to the action and to the state of the world are both endogenous, voters may not pay enough attention the state with respect to the ex ante optimum. A reduction in the total cost of attention does not correct this inefficiency and can even reduce welfare. This model can be a demand‐driven explanation of the under‐provision of analytical contents by news channels.  相似文献

The objective of the present study is to verify the flypaper effect of 476 Brazilian municipalities from 2005 to 2012, considering the new variables as instruments of grants. Political alignment, alignment of the party, and coalition of the mayor with the federal president and of the state governor were considered as instruments of grants. A municipal tax autonomy index was considered as a control variable, which represents the percentage of local taxes in the municipal total revenues. The results allow concluding that the flypaper effect exists in Brazilian municipalities and is intensified by the alignment of the representatives in the same way of theoretical literature (Hamilton 1983; Hines & Thaler 1995; Inman 2008) and previous empirical studies in Brazil. Moreover, evidences of higher flypaper effect were found in municipalities with low tax autonomy.  相似文献
