The product life cycle trap

Many of America's most successful companies have gone through a life cycle similar to the product life cycle. They began as innovators, and then grew to be giants in their markets. But, as their products mature, they need new products to continue company growth. However, the organizational structure of an established company is no longer suited for innovation. The authors provide some insight into this cycle, and offer some solutions for big companies which need new products.     

Price level determinacy with an interest rate policy rule and rational expectations

This paper reconsiders a result obtained by Sargent and Wallace namely, that price level indeterminacy obtains in their model if the monetary authorities adopt a feedback rule for the interest rate rather than the money stock. It is shown that the indeterminacy vanishes if the interest rate rule is chosen so as to have a desired effect on the expected quantity of money demanded. This holds even if considerable weight is given, in the choice of a rule, to the aim of smoothing interest rate fluctuations.     

Monetary and Fiscal Theories of the Price Level: The Irreconcilable Differences

The fiscal theory of the price level (FTPL) has attracted muchattention but disagreement remains concerning its defining characteristics.Some writers have emphasized implications regarding interest-ratepegging and determinacy of rational expectations solutions,whereas others have stressed its capacity to generate equilibriain which price-level trajectories mimic those of bonds and differdrastically from those of money supplies. We argue that theFTPL attained prominence precisely because it appeared to providea theory whose implications differ greatly from conventionalmonetary analysis; accordingly we review monetarist writingsto identify the primary distinctions. In addition, we reviewrecent findings concerning learnability—and thereforeplausibility—of competing rational expectations equilibria.These indicate that when FTPL and monetarist equilibria differ,the latter are more plausible in the vast majority of cases.Under Ricardian assumptions, necessary for clear distinctions,theoretical analysis indicates that fiscal and monetary coordinationis not necessary for macroeconomic stability.

Applying portfolio theory to global bank lending

Portfolio theory provides some insights into how a bank should manage its global exposures. Practical application of some of the principles of portfolio analysis is possible if comparable credit ratings are available and if the impact on each loan's rating of likely future events can be assessed. If further restrictive assumptions are made about which quality dimensions of the portfolio are more important (and how much more important), and if judgements can be quantified about what risk-return tradeoffs are acceptable, then it is possible to derive measures to guide exposure and pricing decisions. This article is related to the other papers in this special issue in that country and corporate risk assessment methodologies can provide important inputs into the portfolio analysis. This paper, however, attempts to go beyond the evaluation of risk at the level of individual companies, countries, or other loan customers, and to focus instead on the problem of managing the riskiness of the overall bank loan portfolio.     

Farmers’ Willingness to Pay for a Tuberculosis Cattle Vaccine

We use contingent valuation (CV) and choice experiment (CE) methods to assess cattle farmers’ attitudes to and willingness to pay (WTP) for a bovine tuberculosis (bTB) cattle vaccine, to help inform vaccine development and policy. A survey questionnaire was administered by means of telephone interviews to a stratified sample of 300 cattle farmers in annually bTB‐tested areas in England and Wales. Farmers felt that bTB was a major risk for the cattle industry and that there was a high risk of their cattle getting the disease. The CE estimate produced a mean WTP of £35 per animal per single dose for a vaccine that is 90% effective at reducing the risk of a bTB breakdown and an estimated £55 for such a vaccine backed by 100% insurance of loss if a breakdown should occur. The CV estimate produced a mean WTP of nearly £17 per dose/per animal/per year for a vaccine (including 100% insurance) which, given the average lifespan of cattle, is comparable to the CE estimate. These WTP estimates are substantially higher than the expected cost of a vaccine which suggests that farmers in high risk bTB ‘hotspot’ areas perceive a substantial net benefit from buying the vaccine.
