Many studies of the local economic impacts of individual highway projects rely on overly narrow measures of economic benefits. Another type of research, focusing on economic productivity, defines benefits more broadly but is also limited by geographic and functional aggregation constraints. This paper attempts to bridge these two perspetives, describing how project-specific analysis methods can shed light on the overall macroeconomic effects of transportation infrastructure spending.

A 484-sector Massachusetts static input - output (MIO) model is conjoined with the Massachusetts Economic Policy Analysis (MEPA) model which includes supply relationships, industrial location responses to changing costs, and a production function allowing substitution among inputs. This makes it possible to draw upon the distinctive features of both models. The technique is demonstrated by a study that analyzes the effect on the Massachusetts economy of the expansion of a container port facility at Boston. The approach presented here has general applicability to policy analysis and planning studies that require both the detailed regional interindustry interactions captured by a disaggregated input - output model and the cost, price, supply, location, and demand interdependencies which are endogenous in the best regional forecasting and policy simulation models.

This report describes the theoretical and technical similarities and differences between the RIMS II, IMPLAN, and REMI models, and provides a general guide for when it is appropriate to use each of the three models.

This report is a study of the anticipated economic impacts of a major infrastructure investment in south Georgia. Dubbed the "power alley initiative," the proposed investment would enhance an east-west transportation corridor, expand telecommunications infrastructure, create new electric power generation and distribution capacity, and develop a large natural gas pipeline along the corridor.

This paper discusses the Major Corridor Investment-Benefit Analysis System. The purpose of this system is to provide an analytical tool for use by INDOT in evaluating and comparing the impacts of major corridor highway investments in the state. The system combines a statewide travel demand model, a user benefit/cost analysis model, and a regional econometric model.

This study describes the positive economic impacts of transportation investment in Wisconsin through both quantitative and qualitative research. As businesses respond to the cost savings and accessibility benefits of transportation investments they become more competitive and the benefits reverberate throughout the entire economy. The direct economic effects of transportation investment include improved access to labor and specialized skills; statewide business attraction, expansion, and retention; reduced logistics costs; and greater tourism activity.

The report evaluates the potential economic and demographic effects stemming from a major upgrade to US Highway 54 and the ensuing enhancement of the New Mexico transportation network.

This analysis identifies and analyzes the economic and demographic impacts of the construction of transportation infrastructure along the Wasatch Front from 2004 through 2030, particularly focusing on the federally financed portion.

The purpose of this study is to illustrate the importance and interconnectedness of Bradley to Connecticut's economy and future economic development. To show the effects of the airport on the level of economic activity in the state of Connecticut, the broadly defined economic impact measures of jobs (employment), value added (gross regional product), and personal income (including wages) is used. In providing a comprehensive understanding of the effects of the airport on the state economy, the report underscores the critical links between air transportation and key industries in Connecticut. In addition, the report emphasizes how technology and an expanding global marketplace make efficient modes of travel paramount for regional competitiveness and shows the size and importance of Bradley relative to other components of the transportation infrastructure.

The primary objective of this study is to describe how improvements to the state's transportation infrastructure might "enhance the business climate and the state's competitive position in economic development, with a focus on the potential to expand the sale of goods to markets outside the state by strenghtening the state's transportation infrastructure."

This report quantifies the economic impact of implementing the O'Hare Modernization Program and the related roadway improvements on DuPage County.

This report will be of interest to individuals who are concerned about the economic implications of congestion. This study examines how traffic congestion affects producers of economic goods and services in terms of business costs, productivity, and output, and how producers are variously sensitive to congestion. Past attempts to assess the economic implications of congestion have found that this is a difficult relationship to document. This study should be viewed as an incremental step toward a broader definition of the economic costs of congestion. The research shows the many facets of congestion impacts on businesses and local economies, by illustrating the types of data necessary to document those costs and demonstrating how analysis can be carried out and ultimately improved.

This report estimates the economic impact - in terms of jobs, compensation and tax revenues - of a major contraction involving one or more of the Detroit Three
automakers (General Motors, Ford, and Chrysler).

This memorandum studies the economic impacts of the government investments in General Motors under the Troubled Asset Relief Program in 2009.

This paper explores the role that economic impact analysis can play in prioritizing transportation investments.

This assessment addresses concerns regarding proposed improvements to interstate highway I-95 in North Carolina as well as alternative funding options for said improvements.

This paper analyzes the impacts of alternate mechanisms for funding short-term improvements to "jump start" infrastructure enhancements in the Metro atlanta area.

This brief examines the economic progress and accomplishments of southern California, specifically focusing on the 2012-2035 Regional Transportation Plan.
