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

This article carries out an empirical examination of the origin of the differences between immigrant and native-born wage
structures in the Spanish labour market. Special attention is given in the analysis to the role played by occupational and
workplace segregation of immigrants. Legal immigrants from developing countries exhibit lower mean wages and a more compressed
wage structure than native-born workers. By contrast, immigrants from developed countries display higher mean wages and a
more dispersed wage structure. The main empirical finding is that the disparities in the wage distributions for the native-born
and both groups of immigrants are largely explained by their different observed characteristics, with a particularly important
influence in this context of workplace and, specially, occupational segregation.

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

We estimate a sequential model of schooling to assess the major contributing factors to the large gender imbalance in educational attainment within racial groups. First, we find that differences between males and females in measures of early behavior account for the majority of the gender gap for each racial group. Second, we show that black males have the largest response to improvements in family background characteristics, such that equalizing the distribution of family background characteristics for black and white youths reduces the gender gap in college enrollment among black youth by 50%. 相似文献

This paper examines how different forms of accumulated exploitable knowledge—i.e., export experience with the current firm and past entrepreneurial experience—stimulate export destinations, defined as the number of foreign markets where businesses sell their products/services. The proposed hypotheses are tested on a unique sample of Costa Rican entrepreneurial businesses for 2017. Results from the sequential deductive triangulation analysis (QUAN → qual) reveal that the ambidextrous connection between export experience with the current firm and past entrepreneurial experience is an essential prerequisite for explaining export destination figures. Also, the positive effect of export experience with the current business on export destinations is more prevalent among firms created by serial entrepreneurs. These findings corroborate our argument line on the importance of generative-based learning processes. Furthermore, the results of the qualitative analysis suggest that task-specific international experience and experience gained through past business venturing are relevant micro-foundations of international business expansion in the context of the export destinations of entrepreneurial firms. 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
