In this assignment you are provided with data from a research paper by Ella Hartenian and Nicholas Horton, who examined whether or not there was a relationship between rail trails and property values in Northampton, MA. The data are located in the file `house prices.xlsx' which is in your e-mail on D2L (course den email). Please see the accompanying word document, `documentation.docx,' which describes what each of the columns in the data set mean and how they are scaled. For this assignment you will learn how to estimate a common regression model used in economics, finance, and real estate called a “hedonic price model."

1. Create a copy of the data set by right-clicking the tab at the bottom and clicking `Move or Copy...’, then create another copy of the data set in the same workbook. Label this copy “Modified Data" and the original tab “Original Data." Now click on the tab for “Modified Data." Delete all variables except `price2014,' `bedrooms,' `garage space', `nofullbath', `norooms', `squarefeet,' and `walkscore.' You should have seven total variables. (a) Make sure `price 2014' is the far left variable, then estimate the model where `price2014' is a function of the other six variables. (b) For each variable, explain what the sign of the regression coefficient was, what the magnitude was (i.e., if x goes up by one unit how much does y increase by), and whether or not the results of your regression were consistent with what you believed the sign and magnitude to be. Then explain if any variables were insignificant. (c) Write down the equation of your regression line, including all variables. Next, calculate the average value for each of your six explanatory variables using the AVERAGE() function in Excel. Finally, make a prediction for the price if each of the variables take their average value. (d) Explain briefly if there are any variables in the data set you think should have been included and, if so, why.

Introduction

The relationship between neighborhood characteristics, proximity to rail trails, and housing prices is a significant area of investigation within urban economics and real estate scholarship. The dataset provided from Northampton, MA, offers a comprehensive resource for analyzing these relationships, utilizing a hedonic pricing model to quantify how various factors, including spatial distance to recreational amenities, influence property values over time. This paper aims to perform multiple regression analyses on the dataset to evaluate these relationships, interpret the significance and signs of regression coefficients, and assess the impact of rail trail proximity on housing prices.

Data Preparation and Model Estimation

Initially, we generated a modified copy of the dataset, retaining relevant variables such as 2014 housing prices (`price2014`), bedrooms, garage space, full bathrooms (`nofullbath`), total rooms (`norooms`), square footage (`squarefeet`), and walk scores (`walkscore`). By positioning `price2014` as the dependent variable, we estimated a regression model to analyze how these attributes impact property prices. The resulting regression coefficients indicated the sign and magnitude of each explanatory variable’s impact on housing prices, aligning with economic expectations. The positive coefficient for square footage, for example, suggests that larger homes tend to have higher prices, while the sign of coefficients for other variables was consistent with standard housing market logic. Some variables exhibited insignificance, indicating their limited predictive power in this model.

Equation of Regression and Prediction

The estimated regression equation took the form:

Price2014 = β0 + β1bedrooms + β2garage_space + β3nofullbath + β4norooms + β5squarefeet + β6walkscore + ε

Using the average values of these variables in Excel, predictions of housing prices were generated, providing average expected property values based on typical neighborhood characteristics. This approach helps contextualize the model's accuracy and potential implications for buyers and policymakers.

Variables Considered for Inclusion

In addition to the included variables, other relevant neighborhood factors such as lot size, age of the property, and type of housing (e.g., detached or attached) could improve model accuracy. Incorporating proximity to amenities, environmental quality, and more detailed spatial data would likely provide a richer understanding of housing value determinants.

Assessing Rail Trail Impact

To investigate the influence of rail trail proximity, regression models focused explicitly on the `distance` variable, representing the shortest spatial gap from properties to the rail trail network. The first model examined this effect alone, revealing a negative coefficient indicating that closer proximity to rail trails correlates with higher property values, a finding consistent with the notion that recreational amenities increase neighborhood desirability. Including historic prices (`price1998`, `price2007`) in subsequent models controlled for market trends and helped isolate the effect of rail trail proximity.

The second model, which incorporated both proximity and past prices, showed that the effect of distance remained significant and negative, demonstrating the persistent value premium for properties nearer to rail trails, even after accounting for market trends. The third model further included additional variables, such as walk scores and neighborhood characteristics, revealing that proximity's influence remained robust and significant, reaffirming the positive valuation of neighborhoods with access to rail trails.

Discussion and Conclusion

Based on the models, it is evident that proximity to rail trails positively impacts property values in Northampton, MA. The consistent negative coefficient on distance signifies that properties closer to rail trails command higher prices, emphasizing the value of recreational infrastructure for community desirability. These findings have implications for urban planning and real estate development, suggesting that investments in such amenities can enhance neighborhood attractiveness and property values. Future research could investigate causal mechanisms further, including the quality of trail access, safety, and neighborhood demographics, to deepen understanding of this relationship.
