This paper analyzes optimal media planning strategies in a pricing‐advertising competition model where firms can use mass and specialized advertising. We find that although targeted advertising avoids the wasting of ads, firms might find it optimal to mix specialized advertising with the mass media. We also show that the characteristics of the specialized media available crucially affect the outcome of price competition between firms, which can range from a full fragmentation of the market into local monopolies to lower average prices (compared to the case where firms had only mass advertising available). Regarding welfare, we prove that although the use of specialized advertising can lower consumer surplus and drive a fragment of consumers out of the market, this advertising technology is welfare‐improving, and can be Pareto superior. 相似文献

We analyze the contribution of credit spread, house and stock price shocks to the US economy based on a time‐varying parameter vector autoregressive model. We find that the contribution of financial shocks to gross domestic product growth fluctuates from about 20% in normal times to more than 50% during the Great Recession. The Great Recession and the subsequent weak recovery can largely be traced back to negative housing shocks. Housing shocks have become more important for the real economy since the early 2000s, and negative housing shocks are more important than positive ones. Unexpected increases in credit spreads have not been deflationary recently. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

AbstractThis article investigates how contract employment practices adopted by universities—fixed-term contracts and permanent contracts—impact research productivity measured in terms of publications in scholarly journals. The empirical application considers the Spanish public higher education system for the period 2002–2008. We report an inverse U-shaped relationship between the rate fixed-term contracts and the research productivity of Spanish universities. That is, contract policies based on fixed-term contracts are conducive to research productivity; however, beyond a critical threshold value increases in the proportion of fixed-term contracts are associated with declining research productivity. These findings reveal that contract employment policies shape research productivity, and that flexible and balanced contract practices are critical for enhancing universities’ research productivity. The results suggest that the excessive use of fixed-term contracts might create an unstable working environment that limits the universities’ capacity to capitalize on their knowledge workers. Policy implications and future research avenues are discussed. 相似文献

This article develops a method for establishing water prices and their effects in order to provide policy makers an environmentally
and socially optimal range of regional prices for irrigation water. Two prices are determined. The “environmentally optimal
price” of water is defined as the one that internalizes the environmental costs generated by agricultural consumption. The
“social optimally price” of water is defined as the one that maximizes levies on water for agriculture without affecting the
regional economy. The environmentally optimal price is calculated with an economic model built over a Geographical Information
System (GIS) that allows the economic quantification and valuation of the environmental cost of water in different basins.
The optimal price is calculated with a demand curve for irrigation water introduced into a Social Accounting Matrix (SAM)
to observe if the regional economy can accept higher prices without affecting the regional GDP. Potential water prices are
established, ranging from prices that minimize the negative impact in the regional economy to those that totally internalize
the environmental cost of water. 相似文献

We introduce the property of ? -norm-boundedness on totally ordered subsets of Euclidean spaces. We show that when a closed subset X of the Euclidean space n, endowed with a continuous total order ?, is ? -norm-bounded, the order topology and the induced Euclidean topology must coincide on X. This generalizes a recent result by Beardon, proved on connected totally ordered subsets of Euclidean space, because on totally ordered closed subsets of n connectedness is a particular case of ? -norm-boundedness. We also analyze necessary and sufficient conditions for the coincidence of both topologies, and discuss some extension to the infinite-dimensional context. 相似文献

This paper studies the effect of competition on product innovation in the market for digital cameras during the years 1998 to 2001. The analysis is based on a structural dynamic model that is estimated and used to simulate the innovation behavior of firms in counterfactual environments. The model features heterogeneous consumers, who time optimally purchase goods, depending on the expected evolution of the prices and the characteristics of available cameras. On the supply side, firms introduce new camera models and choose their characteristics, accounting for the dynamic value of new products and the optimal dynamic behavior of consumers. The counterfactual simulations imply that an increase in competition in the industry would not have generated better products on average and, depending on the type of competition, would have generated products with lower average quality. 相似文献

In this paper we study the effect of price floor regulations on the organization and performance of markets. The standard interpretation of the effects of these policies is concerned with short‐run market distortions associated with excess supply. Since price controls prevent markets from clearing, they lead to higher prices. While this analysis may be correct in the short‐run, it does not consider the dynamic equilibrium consequences of price controls. We demonstrate that price floor regulations can have important long‐run effects on the the structure of markets by crowding them and creating endogenous barriers to entry for low‐cost retailers. Moreover, we show that these factors can indirectly lower productivity and possibly even prices. We test this in the context of an actual regulation imposed in the retail gasoline market in the Canadian province of Québec and show that the policy led to more competition between smaller/less efficient stations. This resulted in lowered sales, and, despite the reduction in efficiency, did not increase prices. 相似文献

For at least one century, crude oil has been one of the most important commodities for the worldwide economic activity. Important technological innovations, including chemical transformation processes and transportation systems, have been based on the availability or not of crude oil. In this way, a close understanding of the crude oil market dynamics should provide insights in important aspects related to potential directions of technological change for both improving crude oil transformation efficiency and substitution by alternative energy sources. This paper studies the dynamics of the crude oil price for the period from 1986 to 2010. To this end, the entropy time-asymmetry is computed along the price trajectory. Empirical results indicated the presence of a non-regular cyclical behavior with a dominant period of about 4.5 years. Some evidences pointing toward a comovement of entropy time-asymmetry peaks with major US economic recessions are found, suggesting a tight relationship between macroeconomy and crude oil prices. The results are discussed in terms of the major economic events that occurred in the upward and downward cycle periods and potential implications for the design of energy policies. 相似文献

In this paper, I investigate the extent to which secondary and higher education supply constraints affected aggregate educational attainment in Colombia for cohorts born between 1945 and 1981. As was the case in many other countries after World War II, in Colombia, industrialization, urbanization and rapid population growth increased the demand for education and the return to schooling. Although educational expenditures from the central government and the states increased after the 1950s, secondary and tertiary schools' per-pupil inputs declined. Using variation in cohort size within states and over time to proxy for changes in education demand, I find that for cohorts born after 1945, a 10% increase in cohort size reduced high school completion rate by 3%, the college completion rate by 4% and average years of schooling by 1%. Compared to women's educational attainment rates, changes in cohort size had greater negative effects on men's rates. 相似文献

The development of new technologies has had important effects on offline distribution channels and, specially, on the psychological effect and risk perceptions that the existence of the online channel may have on the sales agents. Sales agents are fearful that Internet-based competitors will cannibalize their roles in the organization, and might make them outdated and feel insecure about their jobs. This paper estimates the impact of sales agents’ perceptions of service cannibalization on role ambiguity, risk job uncertainty, employee commitment, and employee productivity, considering development of Internet channel, and multi-channel distribution. Data were collected from 497 sales agents who worked at travel agencies located in Spain. Once the model was specified and identified, its parameters were estimated, and authors used various statistics and indices to evaluate overall adaptation of the model. A structural equation modeling was used to examine the posited relationships. This research reinforces the importance of capturing sales agents’s perceptions, especially concerning job insecurity and other outcomes. Specifically, results suggest sales agents’ perceptions of service cannibalization have an effect on role ambiguity and risk and job uncertainty. This study considers the importance of analyzing perceptions of sales agents by travel agency managers to reduce negative consequences on employees, particularly important in view of multi-channel marketing, when a new marketing channel coexists with a traditional sales force. 相似文献
