The impact on broadband access to the Internet of the dual ownership of telephone and cable networks
In Portugal, until recently, the telecommunications incumbent offered broadband access to the Internet, both through digital subscriber line and cable modem. We estimate the impact on broadband access to the Internet of the structural separation of these two businesses. Using a panel of consumer level data and a random effects mixed logit model, we estimate the price elasticities of demand and the marginal costs of broadband access to the Internet. Based on these estimates, we simulate the effect of structural separation on prices and social welfare. Our estimates indicate that structural separation would cause a substantial welfare increase. These results raise questions about the policy of some countries of allowing the dual ownership of telephone and cable networks. 相似文献

Real exchange rate movements are important drivers of the reallocation of resources between sectors of the economy. Economic
theory suggests that the impact of exchange rates should vary with the degree of exposure to international competition and
with the technology level. We show that both the degree of openness and the technology level mediate the impact of exchange
rate movements on labour market developments. According to our estimations, whereas employment in high-technology sectors
seems to be relatively immune to changes in real exchange rates, these appear to have sizable and significant effects on highly
open low-technology sectors. The analysis of job flows suggests that the impact of exchange rates on these sectors occurs
through employment destruction. 相似文献

The creation of new knowledge is a case in which agents' behaviour can affect the performance of other actors positively, given that new knowledge creates positive externalities in the market. In this context, we investigate the existence of performance spillovers associated with innovation activities by quantifying the innovation produced in surrounding firms and controlling for the fact that a firm is itself an innovation producer. We use data from the Third Community Innovation Survey (CIS III) that measures innovation in a broad way, not reducing it to R&D and patents, which departs from previous literature on spillovers. Furthermore, to tackle the endogeneity of the innovation variables on the firm production decision, we resort to the firm intellectual property protection methods as an instrument. We found a positive spillover of innovation on firm value added. The results also show that process innovation spillovers are more prevalent than product innovation spillovers. 相似文献

This article studies the long-run impact of HIV/AIDS on per capita income and education. We focus on the disincentive to human capital accumulation given by shorter life span. We work with a continuous time overlapping generations model with education and saving decisions, calibrated for a cross-section of countries. The simulations predict that the most affected countries in Sub-Saharan Africa will be in future, on average, 20% poorer than they would be without AIDS. Schooling will decline in some cases such as Botswana, South Africa and Zambia by more than 40%. The impact of population decline was found to be irrelevant. 相似文献

This article aims to understand the determinants influencing the number of association meetings held in countries worldwide and which may be controlled by their economic agents and policymakers. For this purpose, we use a dynamic panel model with data provided by the Data World Bank, the World Travel & Tourism Council, and the International Congress and Convention Association, in a time series of 8 years. The results reveal the importance of the experiences obtained by the tourists in previous meetings, as well as the countries’ need to implement measures to stimulate the dynamism of economic activity and political stability. 相似文献

We analyse the skill premium and the growth rate in an innovator-imitator general equilibrium growth model assuming (i) internal costly investment in both physical capital and R&D, (ii) complementarities between intermediate goods in production and (iii) technological-knowledge diffusion. We find that in the imitator country these three elements influence the economic growth rate and the skill premium. In the innovator country, while the growth rate is affected by costly investment and complementarities, the skill premium is not affected by any of our assumptions. It depends solely on the productive advantage of high-skilled over low-skilled labour, which suggests that the sustained increase in the skill premium observed in several developed countries over the last three decades may have been due to increases in such productive advantage. 相似文献

Project volatility is an essential parameter for real options analysis, and it may also be useful for risk analysis. Many volatility estimation procedures only consider the volatility in the first year of the project. Others consider that different years may have different values of the project volatility. This article takes into account that volatility may change not only with time but also with the state of the project. Two possible definitions for the project volatility are considered, the log-variance and the variance of the project value, and two simulation-based procedures are proposed for estimating state-dependent volatility: two-level simulation and one-and-a-half-level simulation. Computational experiments show that both procedures perform better than the method proposed by Copeland and Antikarov and that the one-and-a-half-level simulation procedure leads to the most accurate estimations of project volatility. 相似文献

This paper analyses the effect of multimarket contact on firms’ behaviour. According to Bernheim and Whinston [1990], firms that meet in several markets for an infinite number of periods may find it profitable to redistribute market power among markets where they are operating. We present evidence supporting this prediction by using data from the Spanish hotel industry. Moreover, we also find that the omission of variables measuring multimarket contact creates a downward bias on the effect of concentration on prices. This result questions previous conclusions about the role of competition in industries where multimarket behaviour is expected. 相似文献

Impacts of Hedonic and Utilitarian User Motives on the Innovativeness of User‐Developed Solutions 下载免费PDF全文
Ruth Maria Stock Pedro Oliveira Eric von Hippel 《Journal of Product Innovation Management》2015,32(3):389-403
When individual consumers develop products for their own use, they in part expect to be rewarded by the use value of what they are creating (utilitarian user motives), and in part expect to be rewarded intrinsically by such things as the fun and learning experience derived from creating it (hedonic user motives). This paper shows a first‐of‐type study to understand the relationship between individual consumers' motives to innovate and the novelty and utility of the solutions they develop. The theoretical framework integrates self‐determination theory and goal‐setting theory. The major findings of this study are that utilitarian user motives positively affect the utility of user‐developed innovations. In contrast, hedonic user motives drive solution novelty; the more an innovator is “in it for fun,” the more novel the solution developed. However, hedonic user motives also have an inverted U‐shaped relationship with solution utility. When the dominant motive for developing an innovation is the joy of the creative process rather than use value, the utility of what is developed is negatively affected. These findings are of research interest, and can be of significant practical interest to producers hoping to benefit from user‐developed innovations. For the first time, it has been possible to show that the adjustment of hedonic rewards, for example by means such as gamification, can affect the nature and utility of solutions individuals create. 相似文献

This editorial summarises the papers published in issue 13.1 so as to raise the bar in applied spatial economic research and highlight new trends. The first paper adopts a scale neutral approach to investigate the spatial mechanisms that cause regional innovation and growth. The second paper claims that population-weighting when calculating indices of regional inequality might lead to inconsistent outcomes. The third paper estimates the effect of distance between family residence and higher education institution on a student's academic performance, thereby accounting for endogenous regressors. The fourth paper shows an inverted U-shaped relationship between economic development at region of origin and the propensity to migrate using a multilevel approach. The fifth paper provides spatial econometric evidence of price competition between sellers of used books on Amazon.com. The last paper estimates a hedonic housing price equation and parameterizes the spatial weight matrix to determine how far back in time buyers, sellers and realtors are looking at the housing market. 相似文献
