Design/Methodology/Approach: By applying the hedonic pricing model, most of the previous studies have reported that house price is significantly influenced by the characteristics of the house itself, its location and surrounding facilities. Based on this, the article adopts the Ordinary Least Squares (OLS) regression in combination with robustness statistics in the model estimation, so the estimated results on house price are reliable and able to be widely applied. Data are collected through the survey into housing projects in Ho Chi Minh and Ha Noi city, which are the two largest cities in Vietnam. Findings: The findings reveal that the hedonic pricing model can be applied to estimate house price in Vietnam’s housing market. This can be said to be a big success in giving first empirical evidence in Vietnam on this matter. Specifically, house price is negatively affected by its proximity to the city center. Also, factors including house size, house type, house structure, number of bedrooms, amenities around the house exert a positive influence on the price. Practical Implications: The estimated results are typical and reliable, which can be applied universally. Originality/Value: The study confirms the hedonic pricing model can be well-applied to accurately estimate the price of houses in Vietnam. More than that, the findings are also essential for other countries, especially those with a nascent housing market like Vietnam. ===== PAGE 1 (score 8, numeric-paren 0, table-words 0, var-words 8) ===== International Journal of Economics and Business Administration Volume VIII, Issue 3, 2020 pp. 416-428 The Hedonic Pricing Model Applied to the Housing Market Submitted 11/04/20, 1st revision 19/05/20, 2nd revision 25/06/20, accepted 30/07/20 My-Linh Thi Nguyen1 Abstract: Purpose: The article applies the hedonic pricing model to estimate house price in the housing market of Vietnam, which is a country with a fledgeling housing market, so the study is expected to bring interesting findings.

ORCID ID: 0000-0001-7475-2502 ===== PAGE 7 (score 32, numeric-paren 1, table-words 5, var-words 16) ===== The Hedonic Pricing Model Applied to the Housing Market 422 PRICE = β0 + β1 SIZE + β2 BEDROOMS + β3 BATHROOMS + β4 CENTER + β5 TYPE + β6 POOL + β7 PARK + β8 STRUCTURE + ε Where: Dependent variable (PRICE): House price (price per square meter). Independent variables: SIZE: House size (square meters); BEDROOMS: Number of bedrooms; BATHROOMS: Number of bathrooms; CENTER: Proximity to the city center (kilometers); TYPE: A binary variable indicating whether the house has a garden (= 1 if yes, = 0 otherwise); POOL: A binary variable indicating whether the house has its amenities such as a hot-tub and/or a swimming pool (= 1 if yes, = 0 otherwise); PARK: A binary variable indicating whether the house has local amenities such as parks, squares, schools or shopping malls (= 1 if yes, = 0 otherwise); STRUCTURE: A binary variable indicating whether the structure is new and modern (= 1 if yes, = 0 otherwise); ε: Error term; βi: Coefficients; β0: Constant. 4. Empirical Results First, the article analyses the correlation among the variables. The result is shown in Table 2 as follows: Table 2.

Table 2 reveals that the distance from the house to the center (CENTER) is negatively correlated to its price (PRICE) while the other independent variables are positively associated with the house price (PRICE). This is in line with what the article has been suggested previously. Table 3. Results of tests on multicollinearity, heteroscedasticity Multicollinearity test Heteroscedasticity test Variable VIF PARK 2.52 Chi2(42) = 89.01 Prob>chi2 = 0.000*** BEDROOMS 2.36 STRUCTURE 2.18 BATHROOMS 1.79 ===== PAGE 8 (score 28, numeric-paren 8, table-words 5, var-words 7) ===== My-Linh Thi Nguyen 423 TYPE 1.73 CENTER 1.41 SIZE 1.14 POOL 1.01 Mean VIF = 1.77 Note: *** indicates significance at the 1% level. Source: Own study. The model is considered to experience no serious issues of multicollinearity (Mean VIF = 1.77). However, heteroscedasticity really exists at the 1% level of significance (Prob>chi2 = 0.000) (Table 3). This means that the estimation using the Ordinary Least Squares regression (OLS) does not provide a reliable result. Thus, robustness statistics is utilized for the estimation, following what have been suggested by White (1980) and recently performed by Bui (2020a). Table 4. Estimation results Dependent variable: House price (PRICE) Variables Coef. P>|z| Constant 17.093*** 0.000 SIZE 0.001** 0.023 BEDROOMS 0.065*** 0.000 BATHROOMS 0.003 0.640 CENTER -0.020*** 0.000 TYPE 0.048** 0.036 POOL 0.002 0.709 PARK 0.187*** 0.000 STRUCTURE 0.050*** 0.000 Number of obs 205 R-squared 85.59% Significance level F(8, 196) = 276.08 Prob>F = 0.000*** Note: ** and *** indicate significance at the 5% and 1% level, respectively. Source: own study. As can be seen from Table 4, the estimation results are significant at the 1% level (Prob>F = 0.000). Specifically, the independent variables can account for 85.59% variation in house price. It can be concluded that the model is appropriate and valid for the practical application. Alternatively, the hedonic pricing model is successfully applied in estimating house price in Vietnam. Furthermore, with a high explanation level of research model and highly-representative dataset, the results can be widely administered. Particularly, CENTER exerts the negative impact (β = -0.020) on PRICE at 1% level of significance whereas PRICE is positively influenced by SIZE (β = 0.001, at 5% level of significance), BEDROOMS (β = 0.065, at 1% level of significance), TYPE (β = 0.048, at 5% level of significance), PARK (β = 0.187, a 1% level of significance), STRUCTURE (β = 0.050, at 1% level of significance). Nevertheless, ===== PAGE 9 (score 13, numeric-paren 0, table-words 1, var-words 11) ===== The Hedonic Pricing Model Applied to the Housing Market 424 the study has not found the significant influence of BATHROOMS and POOL on PRICE. Hence, the estimated results of the model take the following equation: PRICE = 17.093 + 0.001 SIZE + 0.065 BEDROOMS - 0.020 CENTER + 0.048 TYPE + 0.187 PARK + 0.050 STRUCTURE + ε Table 5.

This indicates that houses in bigger size are usually priced more. This finding corroborates the reality and what has been reported by Kain and Quigley (1970), Selim (2009), Amenyah and Fletcher (2013), Shimizu (2014), Yayar and Demir (2014), Ndegwa (2018). Accordingly, big-size houses can meet demand of crowded families, bringing a wide and comfortable space. These houses can also specially be used for their business or offices. - The impact of the number of bedrooms (BEDROOMS) on house price (PRICE): The results show that BEDROOMS positively affects PRICE. This is consistent with the findings of Kain and Quigley (1970), Cebula (2009), Selim (2009), Baek et al. (2019). Accordingly, houses with more bedrooms suit families with many members. These houses allow their guests to stay over. As a result, they are more expensive. - The impact of house location (CENTER) on house price (PRICE): The study supports the negative influence of CENTER on PRICE. This shows that houses far from the center may sell for less than those with a close proximity to the center. This is because people living in the former find it difficult to commute to work or town center. Also, their public amenities are more limited than the latter. This is in line with the results in the studies of Selim (2009), Aluko (2011), Amenyah and Fletcher (2013), Yayar and Demir (2014), Ndegwa (2018). - The impact of house type (TYPE) on house price (PRICE): The findings reveal that PRICE is positively affected by TYPE. In the metropolises with a high population, the presence of garden in a house can help improve people’s living standard. Consequently, this kind of house is higher priced. This finding is consistent with what has been stated by Limsombunchai et al. (2004).
