Recent high natural gas prices have focused attention on competition in European gas markets. In response to anti-trust pressures, many long-term pipeline gas contracts in Europe have shifted from oil-linked indexation to pricing based on traded European gas hub indices. In this short paper I...

Could real-time big data help unravel material firm events? How would it compare with firm disclosure and traditional media in terms of timeliness and completeness? Could big data provide incremental value-relevant information for investors? With these questions in mind, we use a novel data set...

This paper explores the economies of scale and scope in the electricity, gas and water utilities. These issues have a crucial importance in the actual policy debates about unbundling the integrated utilities into separate entities, a policy which has often been supported by the ongoing reforms...

This study presents an empirical analysis of the cost efficiency of a sample of Swiss multi-utilities operating in the distribution of electricity, natural gas and water. The multi-utilities that operate in different sectors are characterized by a strong unobserved heterogeneity. Therefore the...

Maintaining rapid economic growth depends increasingly on productivity gains, particularly in the service sector. Competition has an important role to play in achieving such gains. However, Korea’s development strategy has tended to weaken competition and has left a legacy of government...

Empirical work shows that competition is important for promoting economic growth. However, in Japan the promotion of competition has long been compromised by ministerial guidance and exemptions from the competition law. Thus, the level and growth of productivity have been low in many...

Within this analysis we determine the optimal size (that is, with the minimum average cost) of a water supply enterprise and reconsider the matter of scale economies, using sample data from Japanese water supply organizations. After surveying evidence from previous studies of scale economies in...

There is a consensus that the emphasis on the management of water resources should be put on demand side policies. However, some questions remain to be solved on the supply side, which are frequently absent from empirical studies based on the estimation of cost functions. This paper aims to fill...

A long line of research investigates whether the retail prices of electricity and natural gas send proper signals about scarcity in order to induce efficient consumption. Historically, regulated utilities have not designed tariffs that set marginal prices equal to marginal costs. Currently, some...
