The Redevelopment of Vacant Railway Heritage and the External Effect on House Prices
Sophie Louise Procé June 16, 2018
Abstract. Roughly one fourth of all railway stations in The Netherlands is considered to be cultural heritage. Due to a loss of many traditional railway related functions, a lot of space within these stations became vacant over time. The redevelopment of the station buildings requires large investments and is therefore not always financially feasible. There are, however, policymakers that believe that the redevelopment of cultural heritage has a benefit for the surrounding living area. There are multiple scholars that tried to find the empirical evidence of this external effect. The redevelopment of railway heritage specifically is, however, not examined thus far. This thesis contains an empirical analysis, to explore the external effects of the redevelopment of vacant railway heritage, by analyzing surrounding house prices. With a hedonic regression and a difference-in-differences approach, the external effects of fourteen redevelopment projects of railway heritage are analyzed. Surrounding house prices are regressed before, between and after redevelopment took place. Results show that before redevelopment, railway heritage buildings were considered as a disamenity for the surrounding area. This effect disappeared after redevelopment started, indicating anticipation effects. After redevelopment, the railway heritage buildings seem to have a positive external effect on surrounding house prices. This external effect decreases when distance to the railway stations increases, indicating a linear distance decay effect. Lastly, a separate regression shows that the results of this study could be driven by the stations which are located in the largest municipalities. The findings of this study add evidence to theories on externalities and historic amenities.

1. Introduction There are more than 400 railway stations in the Netherlands. These railway stations are primarily developed and managed by NS Stations (NS Stations, 2017a). A considerable amount of the station buildings is of cultural-historical value, as one fourth is cultural heritage and is listed with a monumental status (NS Stations, 2017b). In the past, these stations facilitated a wide variety of functions, in addition to processing passenger flows. These functions included customs functions, tickets and services, office functions and station managerial homes. However, due to technological developments and a change in travel behavior, these traditional railway-related functions became obsolete over time (Spoorbeeld, 2017). As a result, a considerable amount of space within railway heritage buildings became vacant. Of all railway heritage buildings, around 30 percent deals with high vacancy levels. Furthermore, there exists around 30,000 square meters of vacancy within railway heritage buildings. While railway related functions became obsolete, solutions were sought to redevelop the station buildings. However, there are multiple difficulties that occur with the redevelopment of railway heritage buildings, which makes their redevelopment complex to realize. Firstly, due to their status as cultural heritage, large investments are needed to redevelop and prepare the station buildings for new functions. These investments include high material and reconstruction costs and studies concerning architecture and design. Secondly, the direct benefits of redevelopment do not always compensate for the large investments and high redevelopment costs, even though public grants are sometimes provided (Bazelmans et al., 2013). In addition, it is particularly difficult to find new functions that provide direct benefits for the station buildings in peripheral areas. As a consequence, redevelopment projects concerning railway heritage do not always have a desirable rate of return, especially in peripheral areas (Bazelmans et al., 2013). Thirdly, selling (parts of) the station buildings or letting external parties redevelop the station buildings is, in many cases, not an option. This is due to the fact that NS Stations and Prorail, in most cases, retain ownership of the railway stations, since these stations still process passenger flows. As a consequence, redevelopment of railway heritage can not always be realized and a considerable amount of space within the station buildings remains vacant. The complexities that occur with the redevelopment of railway heritage are comparable to the challenges that many cultural heritage sites currently face. Due to the high redevelopment costs and a complex system of policy frameworks that apply to the redevelopment of cultural heritage, vacancy is becoming a general problem for many owners of cultural heritage sites (Bazelmans et al., 2013). As a consequence, the assessment of the benefits of cultural heritage sites is becoming a critical component for the realization of many redevelopment projects (Rizzo & Throsby, 2006). There are many policymakers that believe that the redevelopment of cultural heritage sites has benefits for the surrounding living area. Furthermore, they believe that the redevelopment of heritage sites can be used as a tool to upgrade neighborhoods (Van Duijn et al. 2016). There are multiple scholars that tried to find empirical evidence of these external benefits (Van Duijn et al. 2016; Koster & Rouwendal 2017. In multiple studies, the house prices of houses in
5 proximity of heritage sites are analyzed. The results of these studies show that the redevelopment of cultural heritage sites can have a positive external effect on surrounding house prices. These results are in line with the idea that the presence of amenities, and historic amenities especially, is positively reflected in surrounding house prices (Lazrak et al., 2014). Given these results, it is of interest to investigate if similar positive external effects occur with the redevelopment of railway heritage buildings specifically. Past studies that do concern the redevelopment of railway stations mainly focus on mobility improvements (Bertolini & Spit, 1998) and do not consider the heritage value of railway stations. This study adds to this research gap by analyzing redevelopment projects concerning heritage stations and surrounding house prices. The results of this study contribute to literature on the value of historic amenities (Brueckner, 1999; Ahfeldt et al. 2013) and the importance of reusing monumental buildings (Jacob’s, 1961). The main objective of this research is to gain insight into the redevelopment of railway heritage and the external effects that this may have on surrounding house prices. These external effects are analyzed by applying a hedonic regression to a dataset that contains data on house prices and housing characteristics, provided by the Dutch Association of Agents (NVM). House prices are analyzed before, between and after redevelopment occurred. The focus of interest is to find the magnitude and reach of the external effects. Finding the external effects of redeveloping railway heritage sites, by analyzing house prices, contributes to theories concerning externalities (Cheshire & Sheppard, 1995; Koster & Rouwendal, 2017). The structure of this thesis is as follows. Section two regards the theoretical framework, which includes theories and literature on cultural heritage and the external effects of redevelopment. In addition, the hypotheses that are tested in the analyses can also be found in section two. Section three contains a description of the methodology that is used in the analysis and a description of the empirical model. A summary of the dataset and descriptive statistics of this study can be found in section four. Lastly, the results of the hedonic analysis are stated in section five, followed by a discussion and conclusion of these results in section six.

2. Literature overview and theoretical framework 2.1 The effect of railway stations on house prices Urban economic theory on railway stations and house prices finds its origin in the Von Thunen model (1826), in which the relation between location and land value is analyzed. The Von Thunen model predicts that there is a negative land-rent gradient. Land prices fall when the distance to the central market increases, in order to compensate for higher transportation costs. The Von Thunen model is based upon the three assumptions of Ricardo (1821). Firstly, Ricardo (1821) assumes that land prices must be treated as residual, as they dependent upon the height of transportation costs and non-land inputs. Secondly, land is allocated to its most profitable use or the highest bidder at that location. Lastly, Ricardo assumes that the supply of land at any location is fixed, as land supply is perfectly inelastic. If transportation rates fall, the Von Thunen model predicts that the distance limit to the central market increases and that the maximum land price increases. The bid-rent rent model builds upon the theory of the Von Thunen model (Alonso, 1964; Alonso, 1971; Evans 1973). In the bid-rent model, land prices also fall as distance to the central market increases, but at a diminishing rate. This is due to the fact that the bid-rent model includes factor substitution. The model predicts that when moving further away from the central market, firms and households will substitute in favour of land. For that reason, close to the central market, firms and households will consume relatively little land and more non-land inputs. As within the Von Thunen model, in the bid-rent model, the value of land reflects the utility derived from accessibility opportunities, which are caused by decreasing commuting costs. In line with these important spatial economic theories, there has long been interest in transportation developments and the effect that these developments may have on surrounding house prices. The first survey which analyzed the effects of railway station developments was conducted in 1846 (Kilpatrick, 2007). This study showed that the London’s rail lines had a positive effect of 10 to 25 percent on rents of surrounding houses, as a result of accessibility improvements. Although the methodology has changed considerably over time, the purpose of this research has remained the same over the years. As a result, numerous studies show a positive relation between proximity to railway stations and adjacent house prices (Voith, 1993; Armstrong, 1994; Garett, 2004; Baum-Snow & Kahn, 2001; Gibbons & Machin, 2005). Voith (1993), studied the effect of railway stations in Philadelphia and found that surrounding house prices had a price premium of 6.4 percent. In addition, Armstrong (1994) found a premium of 6.7 percent for houses in Boston which were located in proximity of railway stations. These results expose the economic benefits of accessibility and show a positive relation between accessibility opportunities and house prices. Moreover, according to the study of McDonald and Osuji (1995) even three years before its construction, Chicago’s Midway Line increased house price within a 1 km radius with 17 percent. However, there are several scholars that suggest that the presence of railway stations may also cause negative externalities such as noise, pollution and crime (Kilpatrick, 2007). With this in mind, Forest et al. (2016) studied the effect of (Metrolink) stations in Manchester on house prices. They found
7 significant decreases in house prices of houses located within 3 kilometers of these stations. Furthermore, there are studies that have been more specific in the way in which railway stations have an influence house prices. In their study, Gatzlaff and Smith (1999) find that lower income areas do often not experience the benefits of railway stations, while higher income areas do. In addition, Bowes and Ihlanfeldt (2001) found that increases in house prices due to railway station developments, are higher further away from the central market. At the same time, they also find evidence that the existence of a parking lot significantly decreases the prices of houses that are located within the immediate vicinity of railway stations. All in all, multiple studies suggest that while proximity to accessibility opportunities, such as railway stations, can have a positive influence on house prices, close proximity to the line or station itself could have a negative influence on surrounding houses (Kilpatrick, 2007).
2.2 The effect of the redevelopment of railway heritage on house prices Roughly one fourth of all railway stations in the Netherlands is considered cultural heritage. This includes stations that are listed with a monumental status1, such as municipal-, provincial- and national monuments. In addition, a number of other railway stations without a listed status is also treated as cultural heritage by NS Stations and Prorail, because of their iconic value. For those reasons, railway heritage includes a wide range of stations, such as Valkenburg (1853), Amsterdam Centraal (1881), Almere Centrum (1987) and Amersfoort (2004) (Spoorbeeld, 2017). There are currently no studies that investigate the external effects that the redevelopment of railway heritage may have on surrounding house prices. There are, however, multiple studies that analyze the effect that cultural heritage sites, in general, have on surrounding house prices (Koster & Rouwendal, 2017; Van Duijn et al. 2016; Coulson & Lechenko 2001; Ruijgrok, 2006, Lazrak et al. 2014). These studies are built upon the theory that differences in (historic) amenities may cause substantial differences in house prices, as households are willing to pay a premium to be close to amenities that provide positive externalities (Roback, 1982). Cultural heritage sites are thus not only enjoyed by its users, but also by residents and firms close to them (Koster & Rouwendal, 2017). In their study, Lazrak et al. (2014) analyzed house prices for 22 years in the Dutch city of Zaanstad. They found that, per additional monument within a 50-meter radius, houses were worth an extra 0.28 percent. Coulson and Lechenko (2001) studied the effect of historic designation on house prices in Texas. They found that historic designation provides positive externalities for surrounding houses. In addition, there are multiple scholars that studied the external effects of investments in cultural heritage sites (Koster & Rouwendal, 2017; Van Duijn et al., 2016). Koster and Rouwendal (2017) analyzed data on investments in cultural heritage and house prices with the use of a repeat sales model.

They constructed an instrument based on yearly fluctuations in the size of national subsidy programs concerning the maintenance of cultural heritage. Their results show that a one million euro per square kilometer increase in investments in cultural heritage leads to a price increase of 1.5 to 3 percent for surrounding houses. Van Duijn et al. (2016) analyzed the external effects of the redevelopment of 36 abandoned cultural heritage sites in The Netherlands, with the use of a hedonic pricing model. They investigated these external effects by analyzing surrounding house prices. Surrounding house prices were regressed before, between and after redevelopment took place. In the model of Van Duijn et al. (2016), it is assumed that houses are effected by the redeveloped of industrial heritage, if they are located within a certain distance from the heritage sites (target area). The results show that before redevelopment took place, the industrial heritage sites seem to have a negative external effect on surrounding house prices. However, if a negative effect was present, it disappeared at the start of the redevelopment project. This implies that the redevelopment of industrial heritage has a positive external effect on the surrounding area.

2.3 Hypotheses Although there are multiple theories that suggest that the redevelopment of railway heritage has a positive effect on house prices, these theories mainly focus on accessibility improvements. However, when the redevelopment of railway stations does not include accessibility improvements, but the preservation of the historic features of the station buildings, different external effects are expected. When heritage sites are abandoned or not maintained properly, multiple studies suggest that these sites could have a negative effect on the surrounding area. However, when heritage sites are maintained properly, theories on historical amenities and externalities suggest that heritage sites could have a positive effect on surrounding house prices. Furthermore, this positive effect can even be expected before the redevelopment is finished, indicating anticipation effects. Cultural heritage sites can in this way be seen as amenity by the surrounding area. The following hypotheses test these theories
(1) The presence of railway heritage causes a negative effect on house prices of nearby houses, before redevelopment. (2) The presence of railway heritage causes a positive effect on house prices of nearby houses, after redevelopment has started.

3. Methodology 3.1 Hedonic analysis Since externalities do not have observable market prices, their value can only be measured indirectly (Van Duijn et al. 2016). Methods that are used to analyze the external effects of cultural heritage can be classified into stated preference and revealed preference approaches. Stated preference methods include discrete choice modelling or contingent valuation methodology. These approaches involve asking people for their willingness to pay (WTP) for the benefits that they receive from the presence of cultural heritage, or their willingness to accept compensation for its loss (WTA). Revealed preference approaches include techniques that rely on the observation of market behavior. Hedonic price models are an example of such a technique (Rizzo & Throsby, 2006). In this study, the external effects of the redevelopment of railway heritage are explored with the help of a hedonic regression and data house prices and housing characteristics. In hedonic price models, heterogeneous goods are treated as packages of characteristics. Hedonic regression provides the methodology for estimating the relative contribution of these characteristics on the heterogeneous good, which is the dependent variable. As a result, the hedonic price of each characteristic can be estimated (Rosen, 1974). A primary reason for implementing hedonic analysis to housing markets is to understand the demand for and the value of environmental amenities. Understanding this is essential for predicting the response to changes in amenities in the housing market and the costs and benefits associated with such changes (Sheppard, 1999). There are, however, some limitations for implementing hedonic analysis to housing markets, which must be taken into account. Lack of stochastic independence between observations and collinearity are two econometric problems that occur when estimating hedonic prices. Lack of stochastic independence between observations occurs when the error of an observation is correlated with observations that are nearby. In addition, collinearity occurs when the variance of the characteristics is limited, which decreases the precision of the estimated parameters. This econometric problem can be addressed by including more information in the analysis (Sheppard, 1999). To analyse the effect of redevelopment, house prices that are assumed to be affected by redevelopment (target group) are compared to house prices in a control group. In order to measure the difference between those two groups, a difference-in-differences approach has been applied to the hedonic regression. A simple pre- and post estimation might be biased, due to the fact that unobserved factors may change along with treatment and affect outcomes. A difference-in-differences approach removes this bias and isolates the treatment effect. The use of difference-in-differences methods has become widespread since the work of Ashenfelter and Card (1985). In this approach, the outcomes of the regression can be observed for two groups for two time periods.In this way, the effect of the redevelopment of railway heritage can be found. A detailed description of the target- and control group of this study can be found in the following two sections.
11
3.2 Target group In this study, the target group contains houses that are expected to have received treatment from the redevelopment of railway heritage sites. In line with the study of Van Duijn et al. (2016) it is expected that a house receives treatment if it is located near one of the selected railway heritage sites and has been sold after completion of the redevelopment project. In this study, houses that are located within 1 kilometer of the selected railway stations are considered to be located in the treatment radius. To measure the effect that railway heritage buildings have on surrounding houses, before redevelopment took place, a variable called ‘’Before’’ is included in the regression. In addition, theory suggests that households anticipate to changes in their neighborhood, if information and forecasting is assumed. For this reason, we include a variable called ‘’Between’’ in the regression, which captures the external effect of redevelopment, after redevelopment started and before it is finished. It would be expected that the coefficient of the ‘’Between’’ variable is not significantly different from the ‘’After’’ variable (Van Duijn et al., 2016). The ‘’After’’ variable captures the external effect of railway heritage after redevelopment has finished. The ‘’After’’ variable tells us if redevelopment of railway heritage has a positive influence on surrounding house prices. To check for robustness, the treatment radius is separated in different distance rings to measure the reach of the external effect in section 3.4.
3.3 Control group The control group contains houses that are expected not to be influenced by the redevelopment of the selected railway heritage sites and were therefore sold outside the treatment radius. According to academic literature, the use of outer rings as control areas is standard practice (Van Duijn et al., 2016; Schwartz et al., 2006; Ahfeldt et al., 2013) Houses located in this ring are expected to be similar to the houses in the target group, as they are located in close proximity to houses in the target group. In addition, in order to control for neighborhood characteristics neighborhood characteristics are also added to the regression. In this study, houses that are located between 1 and 2 kilometers from the selected railway heritage sites are considered to be located in the control area. The most important assumed difference between the control- and target group is that the target group is expected to be influenced by the redevelopment of railway heritage sites.

3.4 Defining the empirical model In this study, house prices are regressed on a number of structural characteristics, temporal characteristics, locational characteristics and a variable that reflects the external effect of railway heritage. The first category includes structural characteristics such as housing type, floor area and maintenance condition. The second category refers to the temporal market conditions of the moment in which the house was sold, which is approximated with the use of transaction year dummies. This category corrects for economic conditions, such as inflation. The third category includes locational characteristics which are approximated with the use of neighborhood dummies and neighborhood characteristics. The last variable indicates the presence of an externality, which in this study is the effect of the redevelopment of a railway heritage site located nearby. The empirical model that is used for this study is closely related to the model specification of Van Duijn et al. (2016).
The empirical model is defined as follows:
