The ‘Trade-off’ between Spatial Equity and Economic Efficiency Revisited: Evidence from the US States

The principle aims of regional policy can be encapsulated in terms of ‘spatial equity’ and ‘economic efficiency’. Establishing the relation between these two aims is of fundamental importance. Conventionally, however, it is assumed that there is a conflict or a ‘trade-off’ between them. In this paper, a hopeful view, i.e. that the two aims are complementary rather than competitive, is put forward. The validity of this view is examined empirically using data for the US States covering the period 1972-2005. The obtained results map an instructive framework for regional policy where the scope for reducing regional inequalities is not incompatible with improvements in economic efficiency.regional growth; regional policy; spatial equity; trade-off

Social Equity Impacts of Congestion Management Strategies

This white paper examines the social equity impacts of various congestion management strategies. The paper includes a comprehensive list of 30 congestion management strategies and a discussion of equity implications related to each strategy. The authors analyze existing literature and incorporate findings from 12 expert interviews from academic, non-governmental organization (NGO), public, and private sector respondents to strengthen results and fill gaps in understanding. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework (Shaheen et al., 2017) to identify impacts and classify whether social equity barriers are reduced, exacerbated, or both by a particular congestion mitigation measure. The congestion management strategies discussed are grouped into six main categories, including: 1) pricing, 2) parking and curb policies, 3) operational strategies, 4) infrastructure changes, 5) transportation services and strategies, and 6) conventional taxation. The findings show that the social equity impacts of certain congestion management strategies are not well understood, at present, and further empirical research is needed. Congestion mitigation measures have the potential to affect travel costs, commute times, housing, and accessibility in ways that are distinctly positive or negative for different populations. For these reasons, social equity implications of congestion management strategies should be understood and mitigated for in planning and implementation of these strategies

Social impacts of high speed rail projects: addressing spatial equity effects.

Equity issues are increasingly included among social impacts of transportation investments. Equity implications take into account the distribution of effects among different societal groups (social equity) or regions (spatial equity). The analysis of the spatial distribution of effects is crucial, as certain transportation investments may contribute to increase imbalances between regions, i.e. negative spatial equity impacts. The planning process of a new high speed rail (HSR) corridor should take into account these equity considerations. HSR specific features make it a serious candidate to result in negative equity impacts. These are mainly the significant differences in commercial speeds between HSR and conventional rail, and the spatial separation between HSR stations. In this context, this paper describes and validates a methodology to assess spatial equity impacts of HSR based in the calculation of accessibility indicators. Accessibility analysis is a special type of spatial analysis technique which is increasingly used to assess spatial equity impacts of transportation investments. The proposed methodology is intended to support transport planners when confronted with the task to optimize efficiency and equity objectives. The validity of the methodology is tested with its application to alternative corridor developments of the Spanish HSR network based on the 2020 scenario included in the Spanish Strategic Transport and Infrastructure Plan 2005-2020 (PEIT). The case study application shows that the results are heavily influenced by the selection of the accessibility indicator, each one providing a complementary perspective on equity measurement. In addition, results highlight the important role played by the selection of the commercial speed. In particular, increasing commercial speeds from 220 km/h to 300 km/h in a given corridor results in significant negative impacts on spatial equity, as differences between locations with and without a HSR station are highlighted

Identifying Winners and Losers in Transportation

This paper explores the issues surrounding transportation equity for effects both external and internal to transportation. Several examples of transportation "improvements" imposing transportation costs on more individuals than who are benefited are provided. Beyond counting the number of winners and losers, several quantitative measures of equity are suggested. To that end, transportation benefit cost analyses should include an "Equity Impact Statement". This statement would consider the distribution of the opportunities to participate in decisions and the outcomes of those decisions (in terms of mobility, economic, environmental, and health effects) that different strata (spatial, temporal, modal, generational, gender, racial, cultural, and income) of the population receive. Policy makers would then have additional information on which to base decisions.Environmental Justice, Social and Economic Factors, Equity, Benefit-Cost, Transportation Evaluation .

Private equity in emerging markets

Why is there such a strong private equity market in the United States or the United Kingdom? Why is activity relatively low in several other economically important countries? And why is it zero or close to zero in many emerging regions? Spatial variations of private equity activity result from numerous factors. In this paper I summarize the literature contributions on the determinants of national private equity activity and comment on the consequences for the development of the private equity asset class in emerging markets.Private Equity; Emerging Markets;

Does venture capital investment really require spatial proximity? An empirical investigation

We examine the role of spatial proximity for Venture Capital (VC) investments in Germany. The main database is a survey of 85 personal interviews with representatives of different types of financial institutions. The analysis shows that spatial proximity is far less important for VC investments than is often believed. For example, the results indicate that syndication is partly used as an alternative to spatial proximity. Telecommunication does not work as a substitute for face-to-face contact. On the whole, regional proximity is not a dominant factor in VC partnerships. Therefore, the absence of VC firms in a region does not appear to cause a severe regional equity gap. --Venture Capital,spatial proximity,start-up financing

"Labor Mobility and Economic Geography"

This paper investigates the impact of the heterogeneity of the labor force on the spatial distribution of activities. This goal is achieved by applying the tools of discrete choice theory to an economic geography model. We show that taste heterogeneity acts as a strong dispersion force. We also show that the relationship between the spatial distribution of the industry (the wage differential) and trade costs is smooth and inverted U-shaped. Finally, while Rawlsian equity leads to the dispersion of industry, our analysis reveals that efficiency leads to a solution close to the market outcome, although the latter is likely to involve too much agglomeration compared to the former.

Policy Brief: Social Equity Impacts of Congestion Management Strategies

To better understand the equity implications of a variety of congestion management strategies, researchers at the Transportation Sustainability Research Center (TSRC) at University of California, Berkeley analyzed existing literature on congestion management strategies and findings from 12 expert interviews. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework1 to identify impacts and classify whether social equity barriers are reduced, exacerbated, or both by a particular strategy. The congestion management strategies of interest were categorized into six broader categories: 1) pricing, 2) parking and curb policies, 3) operational strategies, 4) infrastructure changes, 5) transportation services and strategies, and 6) conventional taxation

Spatial accessibility and social inclusion: The impact of Portugal's last health reform

Health policies seek to promote access to health care and should provide appropriate geographical accessibility to each demographical functional group. The dispersal demand of health‐careservices and the provision for such services atfixed locations contribute to the growth of inequality intheir access. Therefore, the optimal distribution of health facilities over the space/area can lead toaccessibility improvements and to the mitigation of the social exclusion of the groups considered mostvulnerable. Requiring for such, the use of planning practices joined with accessibility measures. However,the capacities of Geographic Information Systems in determining and evaluating spatial accessibility inhealth system planning have not yet been fully exploited. This paper focuses on health‐care services planningbased on accessibility measures grounded on the network analysis. The case study hinges on mainlandPortugal. Different scenarios were developed to measure and compare impact on the population'saccessibility. It distinguishes itself from other studies of accessibility measures by integrating network data ina spatial accessibility measure: the enhanced two‐stepfloating catchment area. The convenient location forhealth‐care facilities can increase the accessibility standards of the population and consequently reducethe economic and social costs incurred. Recently, the Portuguese government implemented a reform thataimed to improve, namely, the access and equity in meeting with the most urgent patients. It envisaged,in terms of equity, the allocation of 89 emergency network points that ensured more than 90% of thepopulation be within 30 min from any one point in the network. Consequently, several emergency serviceswere closed, namely, in rural areas. This reform highlighted the need to improve the quality of the emergencycare, accessibility to each care facility, and equity in their access. Hence, accessibility measures becomean efficient decision‐making tool, despite its absence in effective practice planning. According to anapplication of this type of measure, it was possible to verify which levels of accessibility were decreased,including the most disadvantaged people, with a larger time of dislocation of 12 min between 2001 and 2011
