Insights into University Freshman Weight Issues and How They Make Decisions About Eating

The transition from high school to college represents a life turning point during which health behavior paths may be influenced. This study addresses the internal and external factors that guide students' eating decisions as they are understood and relayed by students through qualitative methods. A sample of 102 second semester college freshmen participated in a two‐week data collection period. Results show that many students are caught in a negative cycle of food choices with notable social and environmental determinants impacting both their physical and emotional health.

Detection Avoidance and Deterrence: Some Paradoxical Arithmetic

This paper extends Malik's analysis to the case where criminals' avoidance efforts and public expenditures in the detection of criminals are strategic complements in the aggregate technology of control of illegal behaviors. In this set up, we show that whenever criminals' avoidance efforts are more sensitive to the frequency than to the severity of sanctions, it is always socially efficient to set the fine at the maximal possible level. However, several paradoxical consequences occur: there may exist overdeterrence at optimum; more repressive policies lead to fewer arrests of offenders while more crimes may be committed; at the same time, the society may be closer to the first best number of crimes.     

A Political Agency Theory of Central Bank Independence

We propose a simple theory to explain why, and under what circumstances, a politician delegates policy tasks to a technocrat in an independent institution and then analyze under what conditions delegation is optimal for society. Our theory builds on Holmström's (1982, 1999) “hidden effort” principal–agent model. The election pressures that politicians face, and the absence of such pressures for technocrats, give rise to a dynamic incentive structure that formalizes two rationales for delegation, one highlighted by Hamilton (1788) and the other by Blinder (1998) . Delegation trades off the cost of having a possibly incompetent technocrat with a long‐term job contract against the benefit of having a technocrat who (i) invests more effort into the specialized policy task and (ii) is better insulated from the whims of public opinion. A natural application of our framework suggests a new theory of central bank independence.     

THE WAIVER PORK BARREL: COMMITTEE MEMBERSHIP AND THE APPROVAL TIME OF MEDICAID WAIVERS

Recent growth in Medicaid spending has forced states to look for ways to slow the program's rate of growth. Under the Medicaid program's rules, state governments must submit a waiver to the federal government in order to implement a cost-saving program. The time required to process a waiver varies from 14 days to over three years. This study examines the determinants of the time it takes to process a waiver and the number of revisions required before final approval. The results indicate that an increase in the tenure of the state's delegation to the House oversight committee reduces the time to approval for Freedom of Choice waivers. However, more liberal committee members appear to delay waivers. The results complement the existing literature on the pork barrel by showing that seniority on a committee is an important determinant-not only of monetary benefits but also of nonmonetary benefits.

CAP Forum on E‐Business: Compromise or Customize: XBRL's Paradoxical Power

Business reports are changing in response to regulatory and market demands. Requests by regulators for electronic filings of financial statements and tax forms are increasing and such filings are rapidly becoming mandatory in many countries. In response, extensible business reporting language (XBRL) is a market‐driven, collaborative effort to make electronic filings more useful to, and to reduce the burden on, both publishers and consumers of business reports. XBRL does much more than simply list data items that can be submitted in an electronic filing. XBRL is a complete set of tools for regulators or groups to fully communicate the meanings of and interrelationships among the business reporting concepts. In addition, core sets of concepts from regulators or groups can be extended, expanded, or otherwise modified for more specific communication by jurisdictions, industries, or individual corporations. This unique customization capability lets companies better present their electronic filings as parallels to their paper filings. A “customizable standard” offers new opportunities and new challenges. This paper discusses XBRL's paradoxical power ‐ the trade‐offs between customizing to better parallel existing paper reports and compromising to more closely match the standards, and the research needed for the transition from freeform to customized reports.

Environmental Valuation – To Use or Not to Use? A Comparative Study of the United States and Europe

Valuation methods have been used for five main purposes in environmental decision-making. Cost–benefit analysis (CBA) of projects, CBA of new regulations, natural resource damage assessment, environmental costing, and environmental accounting. The relatively lower importance attached to economic efficiency in environmental decision-making in most European countries compared to the U.S.A., both legally and in practice, might account for our general finding that there are very few valuation studies in Europe which have served as a decisive basis for environmental policy and regulations. However, with EU's goal to establish environmentally adjusted national accounts and to apply CBA to environmental policy and regulations, time seems ripe for an increased use of valuation techniques in Europe.
