India's coal-fired generating capacity doubled between 1990 and 2010 and currently accounts for 70 percent of electricity produced. Despite this, thermal efficiency at state-owned coal-fired power plants in India is significantly lower than at plants in the United States. When matched on age and capacity, heat input per kWh was 8 percent higher at Indian plants between 1997 and 2009. This can only partly be explained by the lower heat content of Indian coal. Electricity sector restructuring in the United States improved thermal efficiency at investor-owned plants; however, electricity sector restructuring in India has yet to improve thermal efficiency at state-owned coal-fired power plants.

The term “audit style” is used to characterize the unique set of internal working rules of each Big 4 audit firm for the implementation of auditing standards and the enforcement of GAAP within their clienteles. Audit style implies that two companies audited by the same Big 4 auditor, subject to the same audit style, are more likely to have comparable earnings than two firms audited by two different Big 4 firms with different styles. By comparable we mean that two firms in the same industry and year will have a more similar accruals and earnings structure. For a sample of U.S. companies for the period 1987 to 2011, we find evidence consistent with audit style increasing the comparability of reported earnings within a Big 4 auditor's clientele.

The SEC Advisory Committee on Smaller Public Companies recommends paid-for research to fill the void created by declining sell-side coverage. Potential conflicts of interest inherent in paid-for research challenge this recommendation. We evaluate whether paid-for research provides value to investors or merely reflects hype. Analyses of one- and two-year-ahead paid-for earnings forecasts fail to identify significant bias. Using a portfolio approach, favorable (unfavorable) paid-for recommendations yield positive (negative) stock returns at release, with upward (downward) drift over the following year. Regressing future stock returns on recommendations and valuation estimates using paid-for analysts' forecasts yields similar results. Further, results fail to indicate significant differences in paid-for and matched sell-side research. Overall, our evidence suggests that paid-for research provides relevant information for the buy-and-hold investor that is comparable to that of matched sell-side research, providing empirical support for the SEC Advisory Committee recommendation.

The federal tax code provides preferential treatment for the production and use of renewable energy. We report estimates of the subsidies' effects on greenhouse gases (GHG) emissions developed in a recent National Research Council (NRC) Report. Due to lack of estimates of the impact of tax provisions on GHG emissions, new modeling studies were commissioned. The studies found, at best, a small impact of subsidies in reducing GHG emissions; in some cases, emissions increased. The NRC report also identified the need to capture the complex interactions among subsidies, pre-existing regulations, and commodity markets.

We ask whether the US government should replace its current discounting practices with a declining discount rate schedule, as the United Kingdom and France have done, or continue to discount the future at a constant exponential rate. We present the theoretical basis for a declining discount rate (DDR) schedule, but focus on how, in practice, a DDR could be estimated for use by policy analysts. We discuss the empirical approaches in the literature and review how the United Kingdom and France estimated their DDR schedules. We conclude with advice on how the United States might proceed to consider modifying its current discounting practices.

The endowment effect, the tendency to value possessions more than non-possessions, is a well-known departure from rational choice and has been replicated in numerous settings. We investigate the universality of the endowment effect, its evolutionary significance, and its dependence on environmental factors. We experimentally test for the endowment effect in an isolated and evolutionarily relevant population of hunter-gatherers, the Hadza Bushmen of Northern Tanzania. We find that Hadza living in isolated regions do not display the endowment effect, while Hadza living in a geographic region with increased exposure to modern society and markets do display the endowment effect.
