FAMILY LIFESTYLE AND ENERGY CONSUMPTION: AN ENERGY ADAPTATION MODEL*

The premise of the paper is that family energy consumption is a consequence of family lifestyle. To facilitate the development of policies that allow families to make satisfactory lifestyle choices as energy resources decline, we explore in detail the relationship between family lifestyle and energy consumption. A model is developed to illustrate the decision making processes that link individual and family behaviour patterns with energy consumption. A series of propositions is derived from the model that relates family values, family effectiveness and family decision making to energy prices, energy conservation adoption, attitude formation and family lifestyle changes. The model can be used by public and private decision makers to identify research and consumer information programs that will facilitate adoption of more energy efficient lifestyles.     

Volume,Volatility, and New York Stock Exchange Trading Halts

Trading halts increase, rather than reduce, both volume and volatility. Volume (volatility) in the first full trading day after a trading halt is 230 percent (50 to 115 percent) higher than following “pseudohalts”: nonhalt control periods matched on time of day, duration, and absolute net-of-market returns. These results are robust over different halt types and news categories. Higher posthalt volume is observed into the third day while higher posthalt volatility decays within hours. The extent of media coverage is a partial determinant of volume and volatility following both halts and pseudohalts, but a separate halt effect remains after controlling for the media effect.     

Gathering Data for Archival,Field, Survey,and Experimental Accounting Research

In the published proceedings of the first Journal of Accounting Research Conference, Vatter [1966] lamented that “Gathering direct and original facts is a tedious and difficult task, and it is not surprising that such work is avoided.” For the fiftieth JAR Conference, we introduce a framework to help researchers understand the complementary value of seven empirical methods that gather data in different ways: prestructured archives, unstructured (“hand‐collected”) archives, field studies, field experiments, surveys, laboratory studies, and laboratory experiments. The framework spells out five goals of an empirical literature and defines the seven methods according to researchers’ choices with respect to five data gathering tasks. We use the framework and examples of successful research studies in the financial reporting literature to clarify how data gathering choices affect a study's ability to achieve its goals, and conclude by showing how the complementary nature of different methods allows researchers to build a literature more effectively than they could with less diverse approaches to gathering data.     

Individual Investors and Local Bias

The paper tests whether individuals have value‐relevant information about local stocks (where “local” is defined as being headquartered near where an investor lives). Our methodology uses two types of calendar‐time portfolios—one based on holdings and one based on transactions. Portfolios of local holdings do not generate abnormal performance (alphas are zero). When studying transactions, purchases of local stocks significantly underperform sales of local stocks. The underperformance remains when focusing on stocks with potentially high levels of information asymmetries. We conclude that individuals do not help incorporate information into stock prices. Our conclusions directly contradict existing studies.     

PRICES AND ENDOGENOUS MARKET STRUCTURE IN OFFICE SUPPLY SUPERSTORES*

We consider the relationship between prices and market structure for office supply superstores in the U.S. which was central to the Federal Trade Commission's opposition to the merger of Staples and Office Depot. Due to potential biases in a standard regression, we employ a two‐stage approach in which a model of endogenous market structure provides correction terms for a second stage price regression. Using a cross‐section of data on market structures and Staples' prices, we find that excluding the correction term substantially distorts the importance of competitors as the two‐stage model yields stronger negative relationships between prices and market structure variables.     

Investment Cycles and Sovereign Debt Overhang

We characterize optimal taxation of foreign capital and optimal sovereign debt policy in a small open economy where the government cannot commit to policy, seeks to insure a risk-averse domestic constituency, and is more impatient than the market. Optimal policy generates long-run cycles in both sovereign debt and foreign direct investment in an environment in which the first best capital stock is a constant. The expected tax on capital endogenously varies with the state of the economy, and investment is distorted by more in recessions than in booms, amplifying the effect of shocks. The government's lack of commitment induces a negative correlation between investment and the stock of government debt, a "debt overhang" effect. Debt relief is never Pareto improving and cannot affect the long-run level of investment. Furthermore, restricting the government to a balanced budget can eliminate the cyclical distortion of investment.     

战略风险评估7步走

“对大多数公司而言,董事会倾注注意力和时间的重心是理解战略及关联风险并提供指导……以及对高管实施战略和风险管理两方面的业绩进行监管。”由美国全国公司董事协会（NACD）出版的《加强美国上市公司监管的关键议定原则》中如是表示。
