How many Enrons? Mark-ups in the stated capital cost of independent power producers' (IPPs') power projects in developing countries

I analyze the determinants of the stated capital cost of IPPs' power projects which significantly influences their price of power. I show that IPPs face a strong incentive to overstate their capital cost and argue that effective competition or regulatory scrutiny will limit the extent of the same. I analyze the stated capital costs of combined cycle gas turbine (CCGT) IPP projects in eight developing countries which became operational during 1990–2006 and find that the stated capital cost of projects selected without competitive bidding is 44–56% higher than those selected with competitive bidding, even after controlling for the effect of cost differences among projects. The extent to which the stated capital costs of projects selected without competitive bidding are higher compared those selected with competitive bidding, is a lower bound on the extent to which they are overstated. My results indicate the drawbacks associated with a policy of promoting private sector participation without an adequate focus on improving competition or regulation.     

Governance choices and policy outcomes in the Latin American and caribbean electricity sector

The paper first provides, for Latin America and the Caribbean, country-specific synthetic quantitative measures of the degree of adoption of governance reforms in the electricity sector, focusing on four key dimensions (market structure, private sector participation (PSP), regulatory autonomy and operational organization). These measures are then correlated with standard policy performance outcomes measures. The findings suggest that, the reforms, considered jointly, were statistically significantly associated with higher technical and process quality but not with social or service improvements. Considered individually, increased regulatory autonomy enjoyed the highest positive correlation with desirable outcomes, but PSP has no significant correlation with any of the outcomes. In sum, as of 2018, governance reforms, considered jointly, had still not delivered on some promised payoffs, notably in addressing energy poverty, although the sensitivity analysis suggests that, for some indicators, the relationships are stronger for larger than for smaller countries.

东亚经济问题与我国改革发展

指出东亚经济在繁荣时期,其成功的模式被过分强调,认为东亚经济增长模式未能随着国际经济环境变迁进行及时变革,是东亚经济的主要问题,也是东亚金融危机的根本原因。认为这些问题在我国不同程度地都存在。因此在剖析东亚经济问题的同时,提出了我国改革与发展的基本思路：开放与改革有效协同;改革的深化要积极稳妥;经济增长方式必须尽快转变,提高产品的国际竞争力和综合国力;面对变化多端的国际环境,政府的管理能力即决策能力、创新能力、应变能力和自我突破、自我完善能力必须尽快提高和有效,才能应付激烈的国际竞争;为攻克这些难题必须同心协力,共度难关。

Utility reforms in developing countries: Learning from the experiences of Delhi

The power sector reforms of Delhi, the capital of India presents an interesting case in the evolution of power sector reforms in India, targeting improvements in distribution side. The Delhi reform design has benefitted from the experience of an earlier partially successful experiment in the state of Orissa. The reform format has tried many new ideas such as defining Aggregate Technical and Commercial (AT&C) losses, auctioning of Discoms based on highest AT&C loss reduction, direct privatization and transitory support provision. In the span of a little more than a decade from the year 2002, there has been tangible progress on many fronts. Other utilities planning the reforms may benefit from this experience. However, newer challenges such as an unexpected increase in power purchase costs with limited scope of passing these costs to the end customers seem to have emerged in the recent years. The paper ends with a cautionary note that for any utility not having access to lower cost power, the distribution reforms will reach a dead-end unless a competitive market is created at the generation side too.
