This dissertation conducts comprehensive analyses on global seaport institutions and port infrastructure productivity. It also examines the determinants of port output and the roles port institutions play in driving port infrastructure productivity. Specifically, the dissertation analyzes the...

Emerging new information and transportation technologies in data processing, communications, and vehicle control and navigation are often expected to become a promising underpinning in tackling the chronic transportation problems. Yet, at least so far, intelligent infrastructure and vehicle...

This paper evaluates how port institutional reforms influenced efficiency gains between 1991 and 2004. We constructed a panel data for port ownership, corporate structure, and port inputs and outputs for 98 major world ports, and we implemented the Malmquist Productivity Index (MPI) model. The...

In all of the world's cities, the most acute transportation problems of congestion, accident and air pollution are severe today and growing worse rapidly. In the US, today as many as 120 million residents live in areas with unhealthy air. Motor vehicle crashes account for 90% of all...

The idea of automated driving dates back more than 50 years, when General Motors (GM) presented a vision of "driverless" vehicles moved under automated control at the 1939 World's Fairs in New York. In the late 1950's, research by industrial organizations conceptualized automated vehicles...

Internet retailing models support supply chains where consumer order locations are decoupled from inventory locations. In this setting, retailers dynamically consider inventory location speculation and postponement to fulfill their orders. Particularly, retailers can manage inventory to fulfill...

Unlike traditional retailers, which use inventory speculation for all their merchandise, Internet book retailers selectively use inventory postponement for specific merchandise items to lower their inventory costs. We develop and test hypotheses that describe merchandise determinants of...

Matching supply, demand, and capacity is made more costly and less efficient when demand variation is amplified into work-in-process, or backlog, variation. Existing research has focused on managing variations in backlog quantity. This paper extends that research by examining how variation in...
