This study explores corporate responses to 1993 legislation that capped the corporate tax deductibility of top management compensation not qualified as “performance‐based.” Our analysis suggests that the cap may have created a focal point for salary compensation but had little effect on total compensation levels or growth rates at firms likely to be affected by the limit. There is little evidence that the policy significantly increased the performance sensitivity of chief executive officer (CEO) pay at affected firms. We conclude that corporate pay decisions have been relatively insulated from this policy intervention.

This article presents an empirical study of market power in the British electricity industry. Estimates of price-cost markups are derived using direct measures of marginal cost and several approaches that do not rely on cost data. Since two suppliers facing inelastic demand dominate the industry, most oligopoly models predict prices substantially above marginal costs. All estimates indicate that prices, while higher than marginal costs, are not nearly as high as most theoretical models predict. Regulatory constraints, the threat of entry, and financial contracts between the suppliers and their customers are considered as possible explanations for the observed price levels.

High and rising executive pay levels over the past two decades have attracted considerable popular and political hostility. As Michael Jensen and Kevin J. Murphy (1990 p. 227) argue, these forces may constrain compensation practices in informal and indirect ways. Our earlier work documents the impact of such indirect political constraints on executive compensation in regulated sectors (Paul Joskow et al., 1993, 1996). This study investigates the political use of the corporate tax code to influence executive-pay decisions more broadly. In particular, we analyze the provision of the Omnibus Budget Reconciliation Act of 1993 (OBRA) that eliminated corporate tax deductibility for compensation in excess of $1 million for the CEO and each of the next four highestpaid executives within a firm. Congressional proponents of this legislation argued that this provision would reduce excessive CEO pay by raising its cost to the corporation. Exemptions for qualified performance-based compensation could have further indirect effects by inducing changes in the structure of executive compensation plans. Given the broad scope for exemptions and the minimal impact that tax deductibility of executive pay typically has on overall corporate profitability, however, the real impact of the tax cap on executive-pay patterns remains an open question. This paper, with Rose and Wolfram (2000), extends analyses by Tod Perry and Marc Zenner (1999) and Brian Hall and Jeffrey Liebman (2000), to provide further evidence on the impact of this legislation on CEO pay.

As both a regulator and an academic, Fred Kahn argued that end-use electricity consumers should face prices that reflect the time-varying marginal costs of generating electricity. This has been very slow to happen in the US, even in light of recent technological advances that have lowered costs and improved functionality for meters and automated demand response technologies. We describe these recent developments and discuss the remaining barriers to the proliferation of time-varying electricity pricing.

A growing number of policies and programs aim to increase investment in energy efficiency, because conventional wisdom suggests that people fail to take up these investments even though they have positive private returns and generate environmental benefits. Many explanations for this energy efficiency gap have been put forward, but there has been surprisingly little field testing of whether the conventional wisdom is correct. This article reports on the results of an experimental evaluation of the nation’s largest residential energy efficiency program—the Weatherization Assistance Program—conducted on a sample of approximately 30,000 households in Michigan. The findings suggest that the upfront investment costs are about twice the actual energy savings. Furthermore, the model-projected savings are more than three times the actual savings. Although this might be attributed to the “rebound” effect—when demand for energy end uses increases as a result of greater efficiency—the article fails to find evidence of significantly higher indoor temperatures at weatherized homes. Even when accounting for the broader societal benefits derived from emissions reductions, the costs still substantially outweigh the benefits; the average rate of return is approximately −7.8% annually.

Current forecasts suggest that the vast majority of growth in energy demand will come from the developing world, and that China will play a major part in that growth. This paper presents evidence suggesting that the shape of the income distribution, which is typically omitted from forecasting models, plays a major role in driving household acquisition of energy-using durable goods in rural China. We use province-level data for rural households to show that the share of the population living above the poverty line is an important determinant of household appliance holdings even controlling for average household income.

What is the optimal response of a resource exporter when a price cap is imposed on its main export? This paper develops a dynamic framework incorporating stochastic prices, financial frictions, and market power to study this novel tool of statecraft. With the right design, a price cap can incentivize increased extraction, stabilizing prices in the global market. But the stabilizing effects diminish when there is leakage outside the cap. Consequently, weak enforcement of the policy worsens the trade-off faced by the sanctioning policymaker. We provide a systematic approach to setting and enforcing an optimal cap level in these circumstances.

We document very low take-up of an energy efficiency program that is widely believed to be privately beneficial. Program participants receive a substantial home “weatherization” retrofit; all installation and equipment costs are covered by the program. Less than 1 percent of presumptively eligible households take up the program in the control group. This rate increased only modestly after we took extraordinary efforts to inform households—via multiple channels–about the sizable benefits and zero monetary costs. These findings are consistent with high non-monetary costs associated with program participation and/or energy efficiency investments.

A new form of secured lending using “digital collateral” has recently emerged, most prominently in low- and middle-income countries. Digital collateral relies on lockout technology, which allows the lender to temporarily disable the flow value of the collateral to the borrower without physically repossessing it. We explore this new form of credit in a model and a field experiment using school-fee loans digitally secured with a solar home system. Securing a loan with digital collateral drastically reduced default rates (by 19 percentage points) and increased the lender’s rate of return (by 49 percentage points). Using a variant of the Karlan and Zinman (2009) methodology, we decompose the total effect on repayment and find that roughly two-thirds is attributable to moral hazard, and one-third to adverse selection. In addition, access to digitally secured school-fee loans significantly increased school enrollment and school-related expenditures without detrimental effects on households’ balance sheets.

While neoclassical models assume static cost-minimization by firms, agency models suggest that firms may not minimize costs in less-competitive or regulated environments. We test this using a transition from cost-of-service regulation to market-oriented environments for many US electric generating plants. Our estimates of input demand suggest that publicly owned plants, whose owners were largely insulated from these reforms, experienced the smallest efficiency gains, while investor-owned plants in states that restructured their wholesale electricity markets improved the most. The results suggest modest medium-term efficiency benefits from replacing regulated monopoly with a market-based industry structure.
