Control of lipid oxidation in cooked ground beef with water and salts*

The effects of exogenous water and salts on lipid oxidation in ground beef were determined. Deionized water, salts, or both, were added to treatment samples. Salts used were sodium chloride, potassium chloride and sodium sulphate, all at 3% concentration. The Thiobarbituric acid (TBA) test was used to assess lipid oxidation. Addition of water at a 10% or 20% level had no effect on rancidity. Sodium chloride and potassium chloride reduced TBA numbers. Adding water to those samples containing potassium chloride and sodium sulphate raised moisture content.     

CURRENCY SUBSTITUTION, U.S. MONEY DEMAND, AND INTERNATIONAL INTERDEPENDENCE

A number of writers have argued in recent years that massive international currency substitution has been a major cause of exchange rate volatility and monetary instability in the United States and other major countries. Such analysis is frequently coupled with recommendations for a return to pegged exchange rates. This paper critically examines the evidence presented for this currency substitution view. It argues that the weight of latest research suggests that direct international currency substitution has not been of major quantitative importance for the U.S. However, empirical evidence supports traditional views that international capital mobility can generate substantial short-run monetary interdependence even under flexible exchange rates. Thus, even though international currency substitution is of little importance to U.S. monetary conditions, a broader range of international considerations may be of considerable importance for the U.S. economy.     

THE EFFECTS OF GOVERNMENT-MANDATED FAMILY LEAVE ON EMPLOYER FAMILY LEAVE POLICIES

The 1993 Family and Medical Leave Act (FMLA) guarantees employees 12 weeks of unpaid leave. However, studies find either small or insignificant effects of the legislation on employment, work, leave-taking, and wages. Perhaps employees are unable to use the leave because it is unpaid or they do not need family leave because they already may take off work via vacation, sick leave, and disability leave policies. If so, then family leave legislation may have increased employer-provided family leave without corresponding effects on employment-related outcomes. This article examines family leave legislation's effects on employers' family leave policies, finding positive effects. (JEL J1, J2, J3 )     

Risk Aversion,Uncertain Information,and Market Efficiency

Abstract. We reexamine and extend tests of the uncertain information hypothesis (UIH) proposed by Brown, Harlow, and Tinic (1988, 1993). We find that their empirical results are sensitive to the sampling procedure employed and that their particular methodology does not sufficiently distinguish between event and nonevent periods. When the sampling procedure is modified to identify only relatively large, isolated events, the test results generally do not support the UIH. Instead, significant price shocks are consistently followed by short-lived price reversals. We observe this behavior following positive and negative events regardless of whether the event is classified as risk increasing or risk decreasing.     

Cost of Recycling Municipal Solid Waste With and Without a Concurrent Beverage Container Deposit Law

The purpose of this article is to contribute to the literature on the effect of beverage container deposit legislation (BCDL) on the cost and amount of the household portion of municipal solid waste recycled. A U.S. General Accounting Office report concluded that dual systems cost more than either alone and that the combination diverts a greater amount of solid waste from landfills, which is supported by this analysis. However, the report's conclusion that a dual system becomes more cost-effective as landfill disposal costs increase cannot be supported over reasonable ranges of the marginal savings from not having to dispose of recycled materials. The cost of recycling is higher in communities with dual systems. Recycling programs without BCDL divert as much or more waste from disposal than with BCDL.
