IMPLICIT PRICE AND DEMAND IN OLIGOPOLISTIC COMPETITION: AN APPLICATION TO THE U.S. TROUT MARKET

This study provides an example of how implicit price and demand models can be developed and used for empirical analysis. In particular, empirical application of these models can quantify the impact of implicit economic variables representing preference, relative price, production efficiency, the degree of price sensitivity to quantity supplied, and substitutability on market price and demand for domestic and imported products. Furthermore, the simultaneous impact of these implicit economic variables on market price and demand can be quantified using these implicit price and demand models.International Relations/Trade,

NORTH KOREAN FOOD SUPPLY AND DEMAND: AN ECONOMETRIC ANALYSIS

This study simulates North Korean food supply and demand using an econometric regression based upon neo-classical economic theory. In doing so, this study at first describes the autarky condition that exists in the closed economy of North Korea and the relationship between pro-military oriented economic policy and deficiency in the dietary needs required by the average North Korean. This study then quantifies the impact agricultural resources and policy have had on the production of food for the sample period of 1995 to 2008. Results show that food production decreases along with a decrease in agricultural input factors and with the implementation of a more pro-military oriented economic policy. Finally, this study simulates ex ante food balance. In order to meet food demand, the rate at which agricultural input factors are made available should be much more greater than the increasing rate of population, regardless of whether pro-market oriented economic policy reforms are implemented or not. And if a more pro-market approach is implemented by North Korea, the food balance appears to recover more quickly from food deficiency to food surplus given a specific level of agricultural resources.Political Economy,

Determining the Impact of Crawfish Imports on U.S. Domestic Prices

The study identifies the linkage between imports and the domestic price of crawfish. The results show a simultaneous increase in imports and domestic prices of crawfish while showing a negative relationship between domestic landings and price. Each model shows that there is a seasonality effect on the domestic price of crawfish. The study also shows that increases in the domestic supplies of shrimp, tilapia, and clams generated increases in the domestic crawfish price while increases in imported and domestic supplies of beef and imported supplies of pork decreased the domestic crawfish price.Demand and Price Analysis, International Relations/Trade,

A Nonclassical Dihydrogen Adduct of S = ½ Fe(I)

We have exploited the capacity of the “(SiP^(iPr)_3)Fe(I)” scaffold to accommodate additional axial ligands and characterized the mononuclear S = 1/2 H_2 adduct complex (SiP^(iPr)_3)Fe^I(H_2). EPR and ENDOR data, in the context of X-ray structural results, revealed that this complex provides a highly unusual example of an open-shell metal complex that binds dihydrogen as a ligand. The H2 ligand at 2 K dynamically reorients within the ligand-binding pocket, tunneling among the energy minima created by strong interactions with the three Fe–P bonds

IMPORT DEMAND SYSTEM ANALYSIS OF THE SOUTH KOREAN WINE MARKET WITH THE SOURCE DIFFERENTATED AIDS MODEL

Under the assumption of block substitutability and partial aggregation, a source differentiated AIDS model was used to estimate South Korean wine import demand. Empirical results indicate that South Korean wine consumers have a strong preference for high quality French wines. French wines are shown to be substitutes for wines from other countries in the South Korean wine market. Since the implementation of a free trade agreement between South Korea and Chile, Chilean wines have steadily increased their market share exhibiting strong price competitiveness in the South Korean wine market.wine, AIDS, block substitutability, import demand, Demand and Price Analysis,

Cigarette smoking and food insecurity among low-income families in the United States, 2001

The goal of this research is to quantify the association between food insecurity and smoking among low-income families. This analysis is a retrospective study using data from the 2001 Panel Study of Income Dynamics, a longitudinal study of a representative sample of U.S. men, women, and children and the family units in which they reside. Family income is linked with U.S. poverty thresholds to identify 2,099 families living near or below 200 percent of the federal poverty level. Food insecurity (that is, having insufficient funds to purchase enough food to maintain an active and healthy lifestyle) is calculated from the eighteen core items in the food security module of the U.S. Department of Agriculture. The results indicate that smoking prevalence is higher among low-income families who are food insecure compared to low-income families who are food secure (43.6 percent versus 31.9 percent). Multivariate analysis reveals that smoking is associated with an increase in food insecurity of approximately 6 percentage points. Given our finding that families near the federal poverty level spend a large share of their income on cigarettes, perhaps it would be prudent for food assistance and tobacco control programs to work together to help low-income people quit smoking.

Restoring Lost Anti-HER-2 Th1 Immunity in Breast Cancer: A Crucial Role for Th1 Cytokines in Therapy and Prevention

The ErbB/B2 (HER-2/neu) oncogene family plays a critical role in the development and metastatic spread of several tumor types including breast, ovarian and gastric cancer. In breast cancer, HER-2/neu is expressed in early disease development in a large percentage of DCIS lesions and its expression is associated with an increased risk of invasion and recurrence. Targeting HER-2 with antibodies such as trastuzumab or pertuzumab has improved survival, but patients with more extensive disease may develop resistance to therapy. Interestingly, response to HER-2 targeted therapies correlates with presence of immune response genes in the breast. Th1 cell production of the cytokines interferon gamma (IFNγ) and TNFα can enhance MHC class I expression, PD-L1 expression, augment apoptosis and tumor senescence, and enhances growth inhibition of many anti-breast cancer agents, including anti-estrogens and HER-2 targeted therapies. Recently, we have identified that a loss of anti-HER-2 CD4 Th1 in peripheral blood occurs during breast tumorigenesis and is dramatically diminished, even in Stage I breast cancers. The loss of anti-HER-2 Th1 response is specific and not readily reversed by standard therapies. In fact, this loss of anti-HER-2 Th1 response in peripheral blood correlates with lack of complete response to neoadjuvant therapy and diminished disease-free survival. This defect can be restored with HER-2 vaccinations in both DCIS and IBC. Correcting the anti-HER-2 Th1 response may have significant impact in improving response to HER-2 targeted therapies. Development of immune monitoring systems for anti-HER-2 Th1 to identify patients at risk for recurrence could be critical to improving outcomes, since the anti-HER-2 Th1 response can be restored by vaccination. Correction of the cellular immune response against HER-2 may prevent recurrence in high-risk patients with DCIS and IBC at risk of developing new or recurrent breast cancer.Fil: Nocera, Nadia F..
