In this article, we investigate scale economies in Norwegian electricity distribution companies using a quantile regression approach. To the best of our knowledge, this is the first attempt to apply this estimation technique when analysing scale economies. We estimate the cost elasticities of the two output components: network length and number of customers, to calculate returns to scale. Our results show large potential of scale economies, particularly for the smallest companies. We also find that returns to scale is increasing over time. These findings have important implications for policymakers when they are deciding the structure of the industry in the future. 相似文献

Previous studies show that resource constraints have mixed effects on innovation and opportunity identification by entrepreneurs. Sometimes, resource constraints lead to identifying more opportunities, whereas in other cases, entrepreneurs see fewer opportunities. This study explores a new approach to reconcile this inconsistency. Using a sample of 219 small‐ and medium‐sized enterprises (SMEs), we explore relationships between supply and demand constraints, on the one hand, and identifying supply and demand opportunities, on the other hand. The results show that supply constraints have a positive effect on identifying supply opportunities but a negative effect on identifying demand opportunities. Similarly, demand constraints have a positive effect on identifying demand opportunities but a negative effect on identifying supply opportunities. Thus, this study shows that resource constraints direct the entrepreneur's attention toward opportunities inside the constrained domain rather than outside the constrained domain. An important consequence for theory is that a complete explanation of the mixed effects of resource constraints should consider different types of resource constraints and different sources of opportunities simultaneously. For practicing entrepreneurs, being aware of this mechanism can prevent missing out on promising opportunities outside the constrained domains. 相似文献

Abstract. This note incorporates basis risk into the futures hedging decision-making problem when the hedger has a state-dependent preference. It is shown that, in an unbiased futures market, a partial hedge is optimal when the marginal utilities in different states are moderately close to each other. Conditions for a Texas hedge or an overhedge are provided. Finally, it is demonstrated that basis risk always reduces the futures trading volume. 相似文献
