This paper investigates the determination factors' variation of real estate price after sub-prime financial crisis, in korea, using a VAR model. The model includes land price, housing price, housing rent (Jensei) price, which time period is from 2000:1Q to 2011:2Q and uses interest rate, real GDP, consumer price index, KOSPI, the number of housing construction, the amount of land sales and practices to impulse response and variance decomposition analysis. Data cover two sub-periods and divided by 2008:3Q that occurred the sub-prime crisis; one is a period of 2000:1Q to 2008:3Q, the other is based a period of 2000:1Q to 2011:2Q. As a result, Comparing sub-prime crisis before and after, land price come out that the influence of real GDP is expanding, but current interest rate's variation is weaken due to the stagnation of current economic status and housing construction market. Housing price is few influenced to interest rate and real GDP, but it is influenced its own variation or Jensei price's variation. According to the Jensei price's rapidly increasing in nowadays, housing price might be increasing a rising possibility. Jensei price is also weaken the influence of all economic index, housing price, comparing before sub-prime financial crisis and it is influenced its own variation the same housing price. As you know, real estate price is weakened market basic value factors such as, interest rate, real GDP, because it is influenced exogenous economic factors such as population structural changes. Economic participators, economic officials, consumer, construction supplyers need to access an accurate observation about current real estate market and economic status.

The purpose of this study was to find affecting consumer's usage motivation on purchase satisfaction and repurchase intension when purchasing fashion products in social commerce. The data were collected via a self-administered questionnaire from 239 male and female who living in Busan with experience in social commerce purchasing fashion products. Using SPSS 20.0 and AMOS 20.0 package, Cronbach's ${\alpha}$, a confirmotory factor analysis and a structural equation modeling analysis were performed. The results are as follows. Hedonic, economical efficiency and interaction without information provide subjective norms significantly influenced the purchase satisfaction. And aforementioned subjective norms significantly influenced repurchase intension, too. The purchase satisfaction positively influenced the repurchase intension. Therefore, social commerce sellers of fashion products ought to offer variety price benift and promotion to raise the purchase satisfaction and repurchase intension. To offer variety price benift, they should respond sensitively to the price set by comparing prices with other sellers. And promotion to raise the purchase satisfaction and repurchase intension need to consider such variety of missions, discount coupons or event and mileage. In addition, they should develop customer service system for interaction with customer and connect to the repurchase increases the purchass satisfaction through faster customer response to the product information or sales, service.

Oil prices have become more volatile as a result of global economic contraction and control measures. Before and during the COVID-19 crisis, this study examines the relationship between oil price swings and daily stock returns in the power sector. The impact is investigated using a panel Vector Autoregressive (VAR) model. Granger causality tests are used to see if oil prices are effective in predicting returns. The dynamic impact of supply shocks is studied using Impulse Response Functions (IRFs). From January 2011 to May 2021, the study used daily data from all listed power sector enterprises on the Pakistan stock exchange. To investigate the differences in reactions between the Pre-COVID and COVID eras, the sample was separated into two groups. Oil shocks are inversely associated with daily firm stock returns. The conclusions are further supported by the lack of impact of stock prices on oil prices. The relationship, however, deteriorates during the COVID pandemic. We could not uncover any evidence of a significant relationship. In developing countries that rely on oil imports, the study sheds light on the utility of oil price shocks in daily stock return predictions.

The purpose of this study is to test the typicality effects to aesthetic response according to product orientation (design-oriented vs function- oriented) and perceived purchase risk. This study overcame the limitations of existing researches which haven't had the consensus about the relationship between typicality and preference and consequently suggested the typicality effect to aesthetic response by analyzing this relationship with product orientation and perceived purchase risk. The results of this study showed the inverted U-shaped relationship in design-oriented products and no relationship in function-oriented products between typicality and preference.

Social Welfare is useful concept for evaluating the effectiveness of an economic policy in micro economics. This paper focuses on Social Welfare(SW) of electricity market incorporating demand response(DR). Competition between DR and generation company is modeled as a simple bid function. DR function can be considered as an negative generation(called Negawatt) and as an element of modified demand function. These two approaches result in the same demand reduction, generation power, and the market price. However, SW in the modified demand function approach is not identical to SW in the Negawatt approach. It makes the numerical index of DR effectiveness less persuasive. This paper proposes modified definition of SW in the demand function approach. The proposed definition of SW leads the DR effectiveness index to be identical to that in the Negawatt approach.

Output prices tend to respond faster to input price increases than to decreases. The 'rockets and feathers' hypothesis of asymmetric price behavior in petroleum market is tested by a full adjustment error correction model. Using monthly data for the period January 1977 to June 2006, evidence is found that there is a significant degree of asymmetry in the adjustment of wholesale prices to increases and to decreases in crude oil price. A similar hypothesis in regard to the exchange rate is also rejected by the data. Using weekly data over the period examined, evidence of asymmetry for gasoline, diesel and heating oil is also found in the transmission of price changes from wholesale to retail: retail prices increase more quickly in response to the wholesale price increases than to wholesale price decreases.
