This study contributes to the literature on estimating market power in homogenous product markets. We estimate a composed error model, where the stochastic part of the firm’s pricing equation is formed by two random variables: the traditional error term, capturing random shocks, and a random...

This paper extends the transformed maximum likelihood approach for estimation of dynamic panel data models by Hsiao, Pesaran, and Tahmiscioglu (2002) to the case where the errors are crosssectionally heteroskedastic. This extension is not trivial due to the incidental parameters problem that...

In this paper, we revisit the problem of self-disconnection among prepayment energy customers. Using metering data from 2.3 million electricity pre-payment customers, we study how often households with an electricity pre-payment meter tend to self-disconnect over the course of a year - and why...

As soon as international financial markets felt reassured in 2003 by the surprisingly neoliberal orientation of President Lula’s government, the ‘spot-the-new-Latin-tiger’ financial brigade became dazzled by Brazil — they just couldn’t have enough of it. So much so, that they had...

Benchmarking of electricity networks has a key role in sharing the benefits of efficiency improvements with consumers and ensuring regulated companies earn a fair return on their investments. This paper analyses the theory and practice of international benchmarking of electricity transmission by...

An EGARCH model in which the conditional distribution is heavy-tailed and skewed is proposed. The properties of the model, including unconditional moments, autocorrelations and the asymptotic distribution of the maximum likelihood estimator, are obtained. Evidence for skewness in conditional...

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...

In financial markets with asymmetric information, traders may have an incentive to forgo profitable deals today in order to preserve their informational advantage for future deals. This sort of manipulative behaviour has been studied in markets with one informed trader (Kyle 1985, Chakraborty...

Many governments who preside over liberalised energy markets are developing policies aimed at promoting investment in renewable generation whilst maintaining the level of security of supply customers have come to expect. Of particular interest is the mix and amount of generation investment over...

The aim of this paper is to discuss the period of energy privatisation and liberalisation which began in the 1980s within its wider historical context. The key issues are: what has been learned from this recent period, and; how significant is it in the light of an energy transition to low carbon...
