This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.

This paper reviews the experience of eight major foreign central banks with policy interest rates comparable to the interest rate on excess reserves paid by the Federal Reserve. We pursue two main lines of inquiry: 1) To what extent have these policy interest rates been lower bounds for short-term market rates, and 2) to what extent has tightening that included increasing these policy rates been achieved without reliance on reductions in reserves or other deposits held at the central bank? The foreign experience suggests that policy rate floors can be effective lower bounds for market rates, although incomplete access to central bank accounts and interest on them weakens this result. In addition, the foreign experience suggests that tightening by increasing the interest rate paid on central bank balances can help reduce or eliminate the need to drain balances. These results are consistent with theoretical results that show that tightening without draining is possible, irrespective of whether excess reserves are large or small.

A randomized-control test of a multimedia nutrition intervention-the Nutrition for a Lifetime System (NLS©)- utilized supermarket receipts to examine effects of NLS treatment on the daily per person nutritional content of participants' supermarket purchases. In regression analyses controlling for background variables, baseline purchases and trends toward increased purchasing, NLS treatment contributed to lower levels of total fat and to higher levels of total fiber and servings of fruits and vegetables at post-test. Redemption of NLS coupons contributed to greater decreases in fat and increases in servings of fruits and vegetables in users' purchases. Implications for future interventions promoting healthier food choices include tailoring program content and addressing broader lifestyle issues such as caloric intake and expenditure.

This article analyzes official reserve-holding behavior in EU countries to assess the effect EMU might have on holdings of dollar reserves. Based on earlier research and new estimates, a wide range of projections is presented for the effect of EMU on the overall demand for reserves and their currency composition. It is argued that official dollar holdings could decline on the order of 35% or more from current dollar holdings, although the range of uncertainty is quite large. The contributions of country-specific factors appear to swamp the systematic components that had been isolated in earlier research.

We use exchange traded options on Canadian dollar futures to estimate the market's risk-neutral distribution for the Canadian dollar in the days before and after the Quebec sovereignty referendum. We employ a relatively new technique that places little a priori structure on the estimated distribution. This lack of structure allows the estimated distribution to reflect the multi-modal nature of expectations associated with the referendum's results. The technique is especially suited to circumstances in which a particular event will reduce a large degree of uncertainty prior to the expiration date of the options. Our estimated distributions are consistent with a significant perceived probability that the Canadian dollar would move up or down by as much as 5 percent as a result of the vote.
