While mobile virtual network operators (MVNOs) increase competition in the mobile telecommunications industry, granting market access to MVNOs may have unwanted consequences. In particular, infrastructure investment by incumbent mobile network operators (MNOs) may be smaller. This paper examines the effects of MVNO entry and access regulation on the investment behavior of MNOs. It uses firm-level data for 58 MNOs in 21 OECD countries during 2000–2008. The results suggest that mandated provision of access is related to lower investment intensity of MNOs, while voluntary access provision has no effect. Although reduced investment incentives do not necessarily correspond to under-investment, this underscores the need for those countries where MVNOs are provided access to address the issue of investment incentives.  相似文献

The objective of this study is to determine the impact of farm credit subsidies on the value of farmland in Canada. The price-components model based on the capitalization principle is developed and estimated using the pooled data from four selected provinces (Quebec, New Brunswick, Manitoba and Saskatchewan) from 1972 to 1991. The results show that increases (decreases) in interest subsidies are expected to increase (decrease) farmland and building values. However, the short-term impact is estimated to be small. The regional analysis shows that the abolition of interest subsidies across the country is likely to have a relatively higher impact on land and building values in Quebec than in the prairie provinces.  相似文献

We revisit the relationship between ancestral distance and barriers to the diffusion of development by replicating previous results with a new genomic dataset on human microsatellite variation. We find a statistically and economically significant effect of ancestral distance from the technological frontier on income per capita. The historical pattern of the effect is hump shaped, peaking between 1870 and 1913, and declining steeply afterwards. This suggests that ancestral distance acts as a temporary barrier to the diffusion of development. We also find that ancestral distance from the frontier is a barrier to the spread of specific technologies and institutions in modern times.  相似文献

Deux modèles de programmation mathématique (MOTAD–cible statique et MOTAD-cible dynamique) ont été utilisés pour analyser l'impact de trois différents programmes d'intervention gouvernementale sur l'allocation optimale des ressources et sur les revenus totaux d'une ferme représentative au Québec. Les résultats montrent que sous les scénarios ASRA/ASREC et RARB, les revenus espérés sont supérieurs pour le RARB comparativement à ASRA/ASREC à un bas niveau de risque, mais ils sont du même ordre lorsqu'on considère les niveaux de risque plus élevés. L'allocation des ressources et la taille de la ferme sont quelque peu différentes. Afin de comparer ces deux programmes d'intervention, deux ratios ont été calculés : les dépenses nettes des gouvernements par rapport au revenu brut et au revenu net de l'entreprise. Les résultats montrent qu'un programme de type RARB est supérieur à un programme de type ASRA/ASREC, et ce, même si les transferts par unité assurée sont les mêmes. Sous le scénario CSRN, les résultats indiquent que les fermes ont des tailles de deux à quatre fois plus petites que dans les scénarios ASRA/ASREC ou RARB et que la stratégie financière des dépôts et des retraits dans le compte CSRN est déterminante dans l'augmentation du revenu espéré de la ferme.  相似文献

This study aims to estimate the level of technical efficiency in milk production and to analyze the relationship between the costs of production, the level of technical efficiency and farm size. Furthermore, the socio-economic variables that characterize the most efficient farms and those producing at lower cost are identified. The results indicate that in Quebec, the level of technical efficiency increases with herd size, but this increase is very small. In Ontario, herd size is not significant to explain technical efficiency. The level of education, the participation in milk recording programs, expenditures per cow fort are and artificial insemination, the quality of hay and the number of years as member of a management club are a11 variables that characterize efficient farms.  相似文献

Measuring the Dynamic Gains from Trade   总被引:11,自引:0,他引:11  
This article investigates the links between trade policy andeconomic growth in a panel of 57 countries between 1970 and1989. It develops a new measure of trade policy openness basedon the policy component of trade shares, using it in a simultaneousequations system to identify the effect of trade policy on severaldeterminants of growth. The results suggest a positive impactof openness on economic growth, with the accelerated accumulationof physical capital accounting for more than half the totaleffect; enhanced technology transmission and improvements inmacroeconomic policy account for smaller effects. This decompositionis robust with respect to alternative specifications and timeperiods. The article also successfully tests whether the modelexhaustively captures the effects of trade policy on growth.  相似文献

African countries, especially sub-Saharan ones, have conflicting interests in multilateral negotiations on agriculture. On the one hand, their economies may be boosted by the price effect induced by agricultural liberalization. On the other hand, multilateral tariff cuts will result in the erosion of preferential margins. Based on an original methodology, using CGE modeling, detailed tariff calculations and predictive analysis, this paper investigates the potential impact of current multilateral negotiations on the value of preferences for African agriculture. It estimates the preferential value to USD 0.7 billion of welfare and USD 1 billion of exports to the Triad markets. Furthermore, it highlights the “cruel dilemma” African countries face in current negotiations, as they gain from ambitious trade liberalization, despite the large preferential erosion, while they suffer from noticeable trade and welfare losses under conservative scenarios.

In this paper, we compare the optimal access regulation under three different market configurations that approximate the different stages of telecommunications market liberalization. We show that in the first stage of market liberalization the regulator has to balance between static efficiency and investment and that the optimal access price may be above marginal cost. In the second stage, two different outcomes are possible. If entrants tend to underinvest, the regulator balances between static efficiency and investment. If entrants tend to overinvest, the regulator sets the access price as low as possible in order to prevent or limit infrastructure duplication. Interestingly, we find that in the third stage of market liberalization the regulator may decide to promote infrastructure duplication and to set the access price above the price in the first stage of market liberalization, even if telecommunications network operators tend to overinvest in infrastructure duplication.  相似文献

Recent studies call for reconsideration of the predictions of resource dependence theory, in light of contemporary industrial and economic environments. This study accordingly investigates the influence of dependence on the strategic choice to innovate by focusing on a rarely studied topic, namely, the sources of dependence. In studying small and medium‐sized video game enterprises, this paper provides empirical validation of dependence phenomena. These companies have limited resources, which inevitably creates dependence, exacerbated in innovative contexts because of the prevalence of negative effects, such as opportunism, abuse of power, limited innovation, or inequitable distributions of economic value. To deal with these negative effects, some enterprises use cooperation or integration strategies to try to minimize their dependence. The strategic choice then might be conditioned. The results of a comparative and qualitative study of five video game developers show that a lack of resources and skills is the primary source of dependence. In addition, a hierarchy of sources of dependence seems to guide the strategic choices of developers to innovate.  相似文献
