The World Bank and others maintain that the major mechanism for improving nutrition in poor communities is increases in income. Aggregate estimates of food expenditure are consistent with such a possibility, implying income/expenditure elasticities close to one. However, the high degree of aggregation at which such estimates are made means that the considerable increase in price per nutrient as income increases is ignored, and the nutrient elasticities are therefore overstated. Estimates for a rural south Indian sample indicate that this bias is considerable and that the true nutrient elasticities with respect to income may be close to zero.

Natural-rate models suggest that the systematic parts of monetary policy will not have important consequences for the business cycle. Nevertheless, we often observe high and variable rates of monetary growth, and a tendency for monetary authorities to pursue countercyclical policies. This behavior is shown to be consistent with a rational expectations equilibrium in a discretionary environment where the policymaker pursues a "reasonable" objective, but where precommitments on monetary growth are precluded. At each point in time, the policymaker optimizes subject to given inflationary expectations, which determine a Phillips Curve-type tradeoff between monetary growth/inflation and unemployment. Inflationary expectations are formed with the knowledge that policymakers will be in this situation. Accordingly, equilibrium excludes systematic deviations between actual and expected inflation, which means that the equilibrium unemployment rate ends up independent of "policy" in our model. However, the equilibrium rates of monetary growth/inflation depend on various parameters, including the slope of the Phillips Curve, the costs attached to unemployment versus inflation, and the level of the natural unemployment rate. The monetary authority determines an average inflation rate that is "excessive, " and also tends to behave countercyclically. Outcomes are shown to improve if a costlessly operating rule is implemented in order to precomrnit future policy choices in the appropriate manner. The value of these precommitments -- that is, of long-term agreements between the government and the private sector -- underlies the argument for rules over discretion. Discretion is the sub-set of rules that provides no guarantees about the government's future behavior.

We introduce a new experimental paradigm to evaluate employer preferences, called incentivized resume rating (IRR). Employers evaluate resumes they know to be hypothetical in order to be matched with real job seekers, preserving incentives while avoiding the deception necessary in audit studies. We deploy IRR with employers recruiting college seniors from a prestigious school, randomizing human capital characteristics and demographics of hypothetical candidates. We measure both employer preferences for candidates and employer beliefs about the likelihood that candidates will accept job offers, avoiding a typical confound in audit studies. We discuss the costs, benefits, and future applications of this new methodology.

The influence of peers could play an important role in the take up of social programs. However, estimating peer effects has proven challenging given the problems of reflection, correlated unobservables, and endogenous group membership. We overcome these identification issues in the context of paid paternity leave in Norway using a regression discontinuity design. We find strong evidence for substantial peer effects of program participation in both workplace and family networks. Coworkers and brothers are 11 and 15 percentage points, respectively, more likely to take paternity leave if their peer was exogenously induced to take up leave. The most likely mechanism is information transmission about the costs and benefits of taking paternity leave, including increased knowledge of how an employer will react. The estimated peer effect snowballs over time, as the first peer interacts with a second peer, the second peer interacts with a third peer, and so on. This leads to long-run participation rates which are substantially higher than would otherwise be expected.

This paper examines vertical arrangements in electricity markets. Vertically integrated wholesalers, or those with long-term contracts, have less incentive to raise wholesale prices when retail prices are determined beforehand. For three restructured markets, we simulate prices that define bounds on static oligopoly equilibria. Our findings suggest that vertical arrangements dramatically affect estimated market outcomes. Had regulators impeded vertical arrangements (as in California), our simulations imply vastly higher prices than observed and production inefficiencies costing over 45 percent of those production costs with vertical arrangements. We conclude that horizontal market structure accurately predicts market performance only when accounting for vertical structure.

This paper examines the demand- and supply-side factors associated with audit partner selection and assignment in the United States. First, we examine whether audit partner gender and experience are associated with board and management gender and experience. Second, we investigate whether engagement audit quality varies with audit partner gender and experience, controlling for selection effects. The results indicate that companies with more gender-diverse boards of directors and top management teams are more likely to have a female lead audit partner. In addition, the experience of the client's board is positively associated with the experience of the lead audit partner. In terms of audit quality, we find that higher audit fees are positively associated with female and more experienced audit partners. Our results shed light on the important role that partner characteristics play in the demand and supply sides of audit quality.

This article explores the business entity concept of the 1964 Concepts and Standards Research Committee of the American Accounting Association and its significance to accounting. The committee's study of the business entity concept has caused it to depart significantly from the concise statement of the concept contained in the 1957 Revision. The committee believes that in referring to concepts underlying the conventions of accounting the use of the term business is inappropriately restrictive. The committee suggests that, in accounting, the term entity concept be used. In accounting the entity with which one is concerned may be defined as an area of economic interest to a particular individual or group. The boundaries of such an economic entity are identifiable by determining the interested individual or group, and by determining the nature of that individual's or that group's interest. An economic entity encompasses the activities, events, and utilization of resources that affect the interest of the individual or group. Simply stated, the committee advocates a user-oriented approach in defining an entity. That is, accounting reports about entities are developed to meet the needs of particular individuals or groups.

The article presents matters related to accounting for students of accounting. The students of today will be the practitioners of tomorrow. One of these is the trend toward a constantly increasing proportion of fixed to total costs. The article presents theory cases for undergraduate courses. After some examination, the writers have found a means of achieving, in part, some of these goals. In a two-hour undergraduate course called "Current Accounting Topics," an effort is made to give students something other than conventional text-book material and to encourage the discussion of matters of theory in a framework that differs from the usual problem-solving approach. The article also presents a simplified three variance technique. The basic concepts involved in calculating the three components that make up the difference between manufacturing expenses incurred and the amount that is charged to production under a standard cost system are difficult matters for most students of cost accounting. The article describes about helping accounting students to learn how to analyze a business transaction.
