Measuring the effectiveness of U.S. rice export promotion programs

AGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 2 2009
Pimbucha Rusmevichientong
Three issues are examined relating to U.S. rice export promotion. First, the responsiveness of U.S. rice export demand with respect to U.S. rice export promotion is measured to determine the quantity impacts of these programs. Second, the overall effectiveness of the programs is examined in terms of whether the benefits exceed the cost. Finally, the optimality of U.S. rice export promotion in terms of expenditure levels is investigated. A double logarithmic econometric export demand equation is estimated to compute the export promotion elasticity while controlling for other demand determinants such as own price, the export price of competing countries, incomes, and exchange rates. Average benefit,cost ratios are computed for U.S. rice export promotion based on a range of excess supply own-price elasticities to compute the effectiveness of the programs. Finally, a marginal simulation analysis is conducted to explore the optimality of the investment in rice export promotion. [JEL Codes: Q17, Q18, Q13]. © 2009 Wiley Periodicals, Inc. [source]

An economic analysis of California raisin export promotion

AGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 2 2003
Harry M. Kaiser
The effectiveness of the California raisin industry's export promotion programs in Japan and in the United Kingdom is addressed in this article. An econometric import demand equation was estimated for each of the two foreign markets. The results indicate that the export promotion programs have increased the demand for California raisins in both Japan and the United Kingdom. The benefit-cost ratios for the Japanese and the United Kingdom markets were computed to be 5:1 and 15:1, respectively; indicating that the benefit of export promotion in terms of expanding export revenue was greater than the cost of the programs. Optimality analysis suggest that, while the current export promotion spending level in Japan is about optimal, the industry should explore the option of investing more money in its export promotion activities in the United Kingdom.

Large Artery Stiffness: Implications For Exercise Capacity And Cardiovascular Risk

CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 3 2002
Bronwyn A Kingwell
SUMMARY 1. Large artery stiffness, or its inverse, compliance, determines pulse pressure, which, in turn, influences myocardial work capacity and coronary perfusion, both of which impact on exercise capacity and cardiovascular risk. 2. In support of a role for arterial properties in exercise performance, aerobically trained athletes (aged 30,59 years) have lower arterial stiffness than their sedentary counterparts. Furthermore, in healthy older subjects (aged 57,80 years), time to exhaustion on treadmill testing correlated positively with arterial compliance. 3. Arterial stiffness is more closely linked to exercise capacity and myocardial risk in patients with coronary disease where, independently of degree of coronary disease, those with stiffer proximal arteries have a lower exercise-induced ischaemic threshold. 4. Moderate aerobic training elevates resting arterial compliance by approximately 30%, independently of mean pressure reduction, in young healthy individuals but not in isolated systolic hypertensive patients. Rat training studies support a role for exercise training in structural remodelling of the large arteries. 5. High-resistance strength training is associated with stiffer large arteries and higher pulse pressure than matched controls. 6. Large artery stiffness is an important modulator of the myocardial blood supply and demand equation, with significant ramifications for athletic performance and ischaemic threshold in coronary disease patients. Moderate aerobic training, but not high-resistance strength training, reduces large artery stiffness in young individuals whereas older subjects with established isolated systolic hypertension are resistant to such adaptation.

THE DEMAND FOR CASINO GAMING WITH SPECIAL REFERENCE TO A SMOKING BAN

ECONOMIC INQUIRY, Issue 2 2008
RICHARD THALHEIMER
This study adds to the limited literature on the demand for casino gaming. The major focus is on the effect of a statewide smoking ban. A system of slot machine demand equations, one each for the three Delaware racinos (racetrack casinos), was developed. The number of slot machines at a racino, at competing in-state racinos, and income were significant demand determinants. Competing out-of-state gaming venues had insignificant effects on gaming demand over the study period. The smoking ban had a significant negative impact on demand, which was not significantly different across the three racinos. The smoking ban reduced gaming demand 15.9%. (JEL L83) [source]

European Integration and Manufactures Import Demand: An Empirical Investigation of Ten European Countries

GERMAN ECONOMIC REVIEW, Issue 3 2002
Ray Barrell
This paper studies import demand in ten European countries over the period 1970,95, and our objective is to investigate whether the process of European integration has affected imports. We provide evidence for parametric change in traditional import demand equations, suggesting that important variables or structural factors are missing from the long-run equations. We present equations based on new trade theory, where effects of technology and foreign direct investment are present. Once we include these there is little evidence that the creation of the Single Market has directly increased aggregated imports in European countries. [source]

Forecasting commercial paper rates

JOURNAL OF FORECASTING, Issue 1 2004
Conway Lackman
Abstract A model previously developed by Lackman (C. L. Lackman, Forecasting commercial paper rates. Journal of Business Finance and Accounting15 (1988) 499,524) for the period 1960 to 1985 is updated to include the 1990s and incorporate statistical techniques relating to tests for stationary conditions not available in 1988. As in the previous model, the demand for commercial paper by each institution (Households (HH), Life Insurance Companies (LIC), Non-Financial Corporations (CRP) and Finance Corporations (FC)) and the total demand is simulated. Simulations of the commercial paper rate are also generated,using just the demand equations (total supply exogenous) and then employing the entire model (supply endogenous) to determine the rate. Simulation periods are from 1960:2 to 2001:4 for all demand simulations. The dynamic simulation of the total demand for commercial paper performs well. The resulting root mean square error, 3.485, compares favourably with the Federal Reserve Boston,Massachusetts Institute of Technology (FRB,MIT) estimate of the commercial paper rate (deLeeuw and Granlich, 1968).

Competition under time-varying demands and dynamic lot sizing costs

NAVAL RESEARCH LOGISTICS: AN INTERNATIONAL JOURNAL, Issue 1 2009
Awi Federgruen
Abstract We develop a competitive pricing model which combines the complexity of time-varying demand and cost functions and that of scale economies arising from dynamic lot sizing costs. Each firm can replenish inventory in each of the T periods into which the planning horizon is partitioned. Fixed as well as variable procurement costs are incurred for each procurement order, along with inventory carrying costs. Each firm adopts, at the beginning of the planning horizon, a (single) price to be employed throughout the horizon. On the basis of each period's system of demand equations, these prices determine a time series of demands for each firm, which needs to service them with an optimal corresponding dynamic lot sizing plan. We establish the existence of a price equilibrium and associated optimal dynamic lotsizing plans, under mild conditions. We also design efficient procedures to compute the equilibrium prices and dynamic lotsizing plans.© 2008 Wiley Periodicals, Inc. Naval Research Logistics 2009 [source]
