A importância estratégica do potássio para o Brasil. Infoteca-e
KINPARA, D. I..
ABSTRACT: This paper presents the strategic importance of potassium (K) in Brazil, focusing four aspects: the function in the plant; the K content of Brazilian soil; the different K forms; and its demand in the Brazilian agricultural system. The K is not a structural element of plants, but it participates in many biochemical plant processes, like carbohydrates and proteins synthesis, showing its economical importance in terms of production. A major problem in Brazilian soils is the leaching process due to the rain regimes. Since k is a very soluble ion in the soil profile, it must be replaced in regular basics to the culture. There are five sources of K, all them of high solubility. Less soluble K compounds have been studied as a way to minimize the...

A KÁVÉ HAZAI ÉS VILÁGPIACA AgEcon
Letenyei, Krisztina.
A kávé kereskedelme a nemzetközi tőzsdéken folyik. Amikor a kínálat meg-haladja a keresletet, túlkínálat van. Ekkor alacsony a kávé ára, a túltermelési válság jelei mutatkoznak: elégetik a kávét. A kistermelők a tönk szélére kerül-nek. Ebben az időszakban a termelők kiirtják, illetve elhanyagolják a kávécser-jéket. A kávéexportáló országok csökkentik a termelést, az exportot is visszafog-ják, a raktárkészlet növekszik. Az elmaradt invesztíció és a rossz időjárási kö-rülmények hatására a kínálat csökken, majd a kereslet meghaladja a kínálatot, ami még ellensúlyozható a raktárkészletek piacra dobásával. Mivel a kávécser-jék csak öt év után fordulnak termőre, a kereslet tartósan meghaladja a kínála-tot. Ekkor a kávéárak a magasba szöknek. Ebben az időszakban...

A Study of the Demand for Medical Services in Taiwan AgEcon
Chung, Rebecca H.; Lee, Jonq-Ying; Brown, Mark G..
This paper presents a version of the household production theory to explain the demand for health. In this study we have explored the factors that influence the demand for medical services and medical expenditures in Taiwan. A negative binomial model was used to study the demand for medical services. We found that the demand for medical services and medical expenditures are related to household composition, household income, family size, occupation of the household head, and living environments. In addition, we found higher usage of medical services on average for those households with medical insurances other than the national health insurance.

A UNIFORM SUBSTITUTE DEMAND MODEL WITH VARYING COEFFICIENTS AgEcon
Brown, Mark G.; Lee, Jonq-Ying.
This study extends Barten's synthetic demand modeling approach to increase the flexibility of the uniform substitute specification of the Rotterdam demand system. Marginal propensities to consume (MPC) vary with budget shares and Slutsky coefficients are defined in terms of varying MPCs. An application of the model to orange-juice products shows that the pattern of income and price elasticities over time is much different than when MPCs are restricted to be constant.

Advertising and Product Confusion: A Case Study of Grapefruit Juice AgEcon
Brown, Mark G.; Lee, Jonq-Ying; Behr, Robert M..
Demand relationships for two closely related products -- grapefruit juice and grapefruit-juice cocktail -- were estimated from grocery-store scanner data to analyze the contention that consumer confusion exists between the two products. Results suggest confusion may exist, with grapefruit-juice advertising not only increasing the demand for grapefruit juice but also for grapefruit-juice cocktail.

Advertising and U.S. Nonalcoholic Beverage Demand AgEcon
Zheng, Yuqing; Kaiser, Harry M..
As a first effort at modeling nonalcoholic beverage demand in a systemwide framework that includes bottled water, this article examines the impact of advertising on the demand for nonalcoholic beverages in the United States. We employed an AIDS (almost ideal demand system) model of five jointly estimated equations that included advertising expenditures as explanatory variables to evaluate annual U.S. consumption of nonalcoholic beverages for 1974 through 2005. Results suggest that advertising increases demand for fluid milk, soft drinks, and coffee and tea, but not for juice or bottled water. Advertising spillover effects occur in over 50 percent of the cases considered, and such effects can be substantial, particularly for advertising of soft drinks, and...

An Analysis of Wal-Mart Refrigerated Orange Juice Sales AgEcon
Brown, Mark G..
In this paper, estimates of the impacts of various factors on the refrigerated OJ sales in Wal-Mart (WM) stores are presented. Data on WM stores, as well as grocery stores doing $2 million or greater annual business, across 52 Nielsen city markets (including the remaining U.S.) were studied. Since WM does not have stores in San Diego, this market was omitted. Weekly data for each city from week ending 3/11/06 through 3/01/08 (104 weeks) were included in the analysis. The relationship between WM refrigerated OJ dollar sales per store and 1) WM and $2million store prices, $2 million store promotions, a dummy variable to test whether sales may spike during periods when some consumers receive their paychecks (middle or end of the month), the number of same...

AN ASSESSMENT OF DYNAMIC BEHAVIOR IN THE U.S. CATFISH MARKET: AN APPLICATION OF THE GENERALIZED DYNAMIC ROTTERDAM MODEL AgEcon
Muhammad, Andrew; Jones, Keithly G..
Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized dynamic Rotterdam model could be derived from the neoclassical intertemporal utility maximization problem; however, no empirical application is provided in his study. This paper provides an empirical application of the generalized dynamic Rotterdam model to the demand for processed catfish products in the U.S. The two-period dynamic Rotterdam model explained a significant amount of the variation in U.S. catfish demand and was preferred to the one-period and static...

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model AgEcon
Muhammad, Andrew; Jones, Keithly G..
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

AN ECONOMETRIC ANALYSIS OF DEMAND FOR MEAT AND FISH PRODUCTS IN KOREA AgEcon
Jung, Jione; Koo, Won W..
This study analyzes the structure of Korean meat and fish product demand. The Linear Approximate Almost Ideal Demand System (LA/AIDS) is used to estimate Korean meat and fish demand. Since the expenditure term is endogenous, the three-stage least squares (3SLS) estimator is used to estimate the demand system. Empirical results indicate that beef imports would increase with increases in per capita income. If imported beef becomes less expensive as a result of the trade liberalization policy adopted by the Korean government, Hanwoo beef would not be competitive and could lose its market share. Pork and chicken would be able to maintain market shares, but most fish products would lose market shares.

AN ECONOMETRIC MODEL OF THE DEMAND FOR FOOD AND NUTRITION AgEcon
LaFrance, Jeffrey T..
A flexible, full rank two model of food consumption that is globally consistent with economic theory, aggregates across income, demographic variables, and variations in micro demand parameters, and accommodates tradeoffs between tastes and nutrition is derived. The econometric demand model is estimated with per capita U.S. consumption of 21 foods on the time period 1919-1994, excluding the World War II years 1942-1946. An approach for inferring the percentage of nutrients available from individual commodities in the U.S. food supply is derived and implemented empirically on the time period 1949-1995 for the nutrients energy, protein, total fat, carbohydrates, and cholesterol. The two sets of model results are combined to generate time paths for income...

An Economic Analysis of Corn-based Ethanol Production AgEcon
Koo, Won W.; Taylor, Richard D..
A global multi-commodity simulation model was developed to estimate the impact of changes in ethanol production on the U.S. corn industry. Increased ethanol production under the Energy Acts of 2005 and 2007 resulted in a significant increase in the price of corn. However, for corn-based ethanol production, the break-even price of corn is approximately $4.52 per bushel with a federal subsidy of $0.51 per gallon of pure ethanol and $2.50 gasoline. With a corn price of $4.52, the economically desirable ethanol production is approximately 11 billion gallons. In order to produce 15 billion gallons of corn-based ethanol and to maintain the price of corn at $4.52 per bushel, supply of corn in the U.S. should be increased substantially through increases in corn...

AN ECONOMIC ANALYSIS OF IMPORT DEMAND FOR CANOLA OIL IN THE UNITED STATES AgEcon
Lordkipanidze, Nazibrola; Epperson, James E.; Ames, Glenn C.W..
The study analyzes the impacts of economic and noneconomic factors on import demand for canola oil. The import demand pattern for canola oil in the United States is influenced by changes in the world's oilseeds market and government oilseeds programs and policies, including tariffs and subsidies. The U.S. import demand for canola oil was specified as a function of its own import price, prices of substitute edible vegetable oils (soybean oil and palm oil), disposable personal income, the Canadian-U.S. (Missing one table)
