This book makes a contribution to the formulation and implementation of production cost models for the modelling of liberalized electricity markets by addressing issues associated with the level of detail in the representation of the underlying power system, the accuracy of the results and the modelling effort. To this end a production cost model was formulated and applied to estimate the short-run marginal cost of the power systems of three important European electricity markets.

The recent public economics literature involves an apparent consensus that income effects reduce the costs of raising revenues and hence increase the desirable level of public good provision. Higher taxes can indeed reduce the demand for leisure - and hence increase the supply of taxed labor - through income effects. However, the consensus is wrong because the income effects of taxes must be considered symmetrically with those from provision of public goods. This paper uses a model with multiple public goods and taxes to derive consistent measures of the marginal benefits of publicly-provided goods and their marginal social costs. With this model, the authors show that either compensated approaches excluding these income effects or uncompensated approaches including them may be used. If an uncompensated measure of the marginal cost of funds is used, however, the benefits of providing public goods should be adjusted with a simple, benefit multiplier not previously seen in the literature. Once this is done, the optimal level of public provision is independent of whether compensated or uncompensated approaches are used. Proper accounting for these income effects - or their omission using a compensated approach - appears to substantially raise the hurdle for government provision where there are substantial taxes bearing on labor.

In a wide variety of settings, spiteful preferences would constitute an obstacle to cooperation, trade, and thus economic development. This paper shows that spiteful preferences - the desire to reduce another's material payoff for the mere purpose of increasing one's relative payoff - are surprisingly widespread in experiments conducted in one of the least developed regions in India (Uttar Pradesh). In a one-shot trust game, the authors find that a large majority of subjects punish cooperative behavior although such punishment clearly increases inequality and decreases the payoffs of both subjects. In experiments to study coordination and to measure social preferences, the findings reveal empirical patterns suggesting that the willingness to reduce another's material payoff - either for the sake of achieving more equality or for the sake of being ahead - is stronger among individuals belonging to high castes than among those belonging to low castes. Because extreme social hierarchies are typically accompanied by a culture that stresses status-seeking, it is plausible that the observed social preference patterns are at least partly shaped by this culture. Thus, an exciting question for future research is the extent to which different institutions and cultures produce preferences that are conducive or detrimental to economic development.

This paper estimates a structural dynamic business investment equation and an error correction model of fixed assets growth on a sample of predominantly small and mid-size manufacturers in India. The results suggest that excessive labor regulation, power shortages, and problems of access to finance are all significant factors in industrial growth in the country. The estimated effects of labor regulation, power shortages and access to finance on the rate of business investment all vary by states' levels of industrial development and. Perhaps more importantly, they also depend on a fourth institutional factor, namely, corruption. The rate of fixed investment is significantly lower where power shortages are more severe and labor regulation is stronger over the full sample, but each of these impacts is also greater for businesses self-reportedly affected by corruption. Although access to finance does not seem to influence the rate of investment for most firms, there is evidence that investment decisions are constrained by cash flow in enterprises that are unaffected by corruption or power shortages. There are nuances to this story as we take into account regional specificity, but the key result always holds that labor regulation, power shortages and access to finance influence the rate of fixed investment in ways that depend on the incidence of corruption. In interpreting this finding, we would like to think of corruption as a proxy for the quality of property rights institutions in the sense of Acemoglu and Johnson (2005). On the other hand, we regard labor regulation and the financial environment of small businesses in India as instances of what Acemoglu and Johnson (2005) call 'contracting institutions'. The analysis finds that the interaction between corruption and other aspects of the institutional environment of fixed investment decisions could be seen consistent with the Acemoglu-Johnson view that the quality of property rights institutions exerts more abiding influence on economic outcomes than the quality of contracting institutions.

The "distance effect" measuring the elasticity of trade flows to distance has been rising since the early 1970s in a host of studies based on the gravity model, leading observers to call it the "distance puzzle". This paper reviews the evidence and explanations. Using an extensive data set of 124 countries over the period 1970-2005, the authors confirm the existence of this puzzle and identify that it only applies to poor countries (the bottom third in per capita income terms in the sample - i.e., the low-income countries according to the World Bank classification, 2006). The analysis shows that this group has intensified trade with closer partners and has chosen new partners that are closer than existing partners, leading to a regionalization of their trade at both extensive and intensive margins (regionalization of trade is absent for the other countries). Combining several methods on cross-section and panel estimates of the gravity equation, the authors estimate that low-income countries exhibit a significant rising distance effect on their trade, around 18 percent between 1970 and 2006. There is no more distance "puzzle" for trade within richer countries (the top third in per capita income terms in the sample). The paper disposes of several previous explanations of the puzzle, and notes that this regionalization could well be a reflection of increased integration of this group of countries in the world economy or greater marginalization.

April 2000 - Transparent, rule-based decisionmaking is important to maintaining public trust in regulated infrastructure. The Buenos Aires water and sanitation concession led to remarkable improvements in delivery and coverage of services and to lower prices for consumers. But a poor information base, lack of transparency in regulatory decisions, and the ad hoc nature of executive branch interventions make it difficult to reassure consumers that their welfare is being protected and that the concession is sustainable. The signing of a concession contract for the Buenos Aires water and sanitation system in December 1992 attracted worldwide attention and caused considerable controversy in Argentina. It was one of the world's largest concessions, but the case was also interesting for other reasons. The concession was implemented rapidly, in contrast with slow implementation of privatization in Santiago, for example. And reform generated major improvements in the sector, including wider coverage, better service, more efficient company operations, and reduced waste. Moreover, the winning bid brought an immediate 26.9 percent reduction in water system tariffs. Consumers benefited from the system's expansion and from the immediate drop in real prices, which was only partly reversed by subsequent changes in tariffs and access charges. And these improvements would probably not have occurred under public administration of the system. Still, as Alcazar, Abdala, and Shirley show, information asymmetries, perverse incentives, and weak regulatory institutions could threaten the concession's sustainability. Opportunities for the company to act opportunistically - and the regulator, arbitrarily - exist because of politicized regulation, a poor information base, serious flaws in the concession contract, a lumpy and ad hoc tariff system, and a general lack of transparency in the regulatory process. Because of these circumstances, public confidence in the process has eroded. The Buenos Aires concession shows how important transparent, rule-based decisionmaking is to maintaining public trust in regulated infrastructure. This paper - a product of Regulation and Competition Policy, Development Research Group - is part of a larger effort in the group to analyze institutional issues in regulated infrastructure. The study was funded by the Bank's Research Support Budget under the research project Institutions, Politics, and Contracts: Private Sector Participation in Urban Water Supply (RPO 681-87).

The authors review the applications of noncooperative bargaining theory to water related issues-which fall in the category of formal models of negotiation. They aim to identify the conditions under which agreements are likely to emerge and their characteristics, to support policymakers in devising the " rules of the game " that could help obtain a desired result. Despite the fact that allocation of natural resources, especially trans-boundary allocation, has all the characteristics of a negotiation problem, there are not many applications of formal negotiation theory to the issue. Therefore, the authors first discuss the noncooperative bargaining models applied to water allocation problems found in the literature. Key findings include the important role noncooperative negotiations can play in cases where binding agreements cannot be signed; the value added of politically and socially acceptable compromises; and the need for a negotiated model that considers incomplete information over the negotiated resource.
