The rapid growth of online search and its centrality to the ecology of the Internet raise many questions for economists to answer: Why is the search engine market so concentrated and will it evolve towards monopoly? What implications does this concentration have for consumers, search engines,...

The allocation of scarce transmission resources has a considerable impact on investment incentives in network industries. We study the long term effects of two common network management regimes on investment in production and transmission facilities. In one case transmission constraints are...

We consider an exchange economy in which there are infinitely many consumers and some commodities are bads, that is, cause disutility to consumers. We give an example of such an economy for which there is no competitive equilibrium or its variants (quasi- or psuedo-equilibrium). We also give...

A structural shift from transaction-based, marginal cost pricing to fee-based service business models often accompanies We emergence of “platform” markets, i.e. multi-sided markets where an intermediary captures the value of the interaction between user groups. The many examples include...

Agent-based modelling is an attractive way of finding equilibria in complex problems involving strategic behaviour, particularly in electricity markets with transmission constraints. However, while it may be possible to demonstrate convergence of learning behaviour to a Nash equilibrium, that is...

This paper presents substantial new evidence on the competitive process that links together industrial economic and international economics. Our time-series data base concerns manufactured product prices and their domestic and international determinants. We identity cointegrating relationships,...

This paper reports an empirical investigation into the welfare impacts of an introduction of private sector participation into the Philippines electricity generation sector, by liberalizing the market for independent power producers (IPPs) during the power crisis of 1990-1993. This study uses a...

Successful cap and trade programs for SO2 and NOx in the US allocate allowances to large emitters based on a historic base line for a period of up to thirty years. National Allocation Plans in Europe allocate CO2 allowances in an iterative approach first for a three then for a five-year period....

The main body of the paper analyses the reasons and the nature of Corporation's remarkable growth during the economic reform years since the late 1970s in China.
