Hypercongestion - the phenomenon that higher traffic densities can reduce throughput - is well understood at the link level, but has also been observed in a macroscopic form at the level of traffic networks; for instance, in morning rush-hour traffic into a downtown core. In this paper, we show...

Purpose: This study is focused on integrating a strategic perspective for bottleneck selection and exploitation according to the DBR methodology. The researchers developed a systematic process of four steps for the implementation of the first two steps of TOC-DBR in Make-to-Order production...

Electricity transmission redistributes environmental impacts across space. We exploit episodes of high electricity transmission system congestion to explore changes in ambient concentrations of air pollutants in the eastern United States. Reducing electricity system congestion decreases ozone...

Due to the call for further integration of European markets and the targeted climate goals, both European electricity systems and markets have undergone continuous changes over the last few decades. As part of these developments, the so-called Flow-Based Market Coupling (FBMC) superseded the...

We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that accounts for hypercongestion (a situation where congestion decreases a road's throughput). We show that the external cost - even when roads are not hypercongested - is substantial,...

We estimate the effect of public transport supply on travel times of motor-vehicle and bus users in Rome, Italy. We apply a quasi-experimental methodology exploiting hourly information on public transport service reductions during strikes. We find that a 10 percent reduction in public transit...

Electricity markets employ different congestion management methods to handle the limited transmission capacity of the power system. This paper compares production efficiency and other aspects of nodal and zonal pricing. We consider two types of zonal pricing: zonal pricing with Available...

Many rural communities in sub-Saharan Africa still lack clean water for basic needs such as drinking and washing. Even where water points have been constructed, many break down prematurely or provide inadequate, seasonal or poor quality water supplies. While techno-managerial factors are...

We use a spatial general equilibrium model with potential commuting of workers between their place of work and their place of residence to analyze the effects of rush hours on the spatial allocation of employment and population, average labor productivity and the housing market. Abolishing...

The Indian telecommunication market is second largest in the world and is growing rapidly. The government is taking several measures such as National optical fiber network (NOFN) project, public WiFi pilot to bridge the gap of digital divide in order to provide Internet services throughout the...

The construction sector is a key enabler for social and economic development worldwide. In Tanzania, the sector growth rate is well above the general economy and has maintained positive growth in response to the country's investments in commercial and residential buildings and infrastructure...

Since 2008 and following the royal directives in the letter addressed to the participants of the sports conference in Skhirat, Morocco, major efforts have been made to promote mass and spectator sports practice in order to improve the sporting landscape and to solve problems related to financing...

We consider a novel generalization of the resource-constrained project scheduling problem (RCPSP). Unlike many established approaches for the RCPSP that aim to minimize the makespan of the project for given static capacity constraints, we consider the important real-life aspect that capacity...

The construction sector plays a critical role in delivering quality infrastructure, which in turn influences the use of natural resource revenues towards achieving structural change and industrial development. We use industrial organization and political economy lenses to describe and understand...

Analysis of open-access common-property natural resource (NR) has occurred under "low" congestion (LC) - where 𝐴𝐶 and 𝑀𝐶 increase with output 𝑄 - and has for the most part ignored the more important congestion categories where 𝐴𝐶 (𝑀𝐶) is backward-bending (negative) and...

This paper explores gene-environmental interactions between family environments and children's genetic scores in determining educational attainment. The central question is whether poor childhood family environments reduce the ability for children to leverage their genetic gifts to achieve high...

When drivers opt for carpooling, road capacity will be freed up, and this will reduce congestion. Therefore, carpooling is interesting for policy makers as a possible solution to congestion. We investigate the effects of carpooling in a dynamic equilibrium model of congestion, which captures...

We study different mixes of private and public supply of roads in a network with bottleneck congestion and heterogeneous users. In our setting, there are two parallel links for one origin and destination pair and two groups of travellers, where the group with higher value of time also has higher...

We consider a novel generalization of the resource-constrained project scheduling problem (RCPSP). Unlike many established approaches for the RCPSP that aim to minimize the makespan of the project for given static capacity constraints, we consider the important real-life aspect that capacity...

This paper focuses on the influence of increased wind and solar power production on the transmission networks in Central Europe. The model ELMOD is employed. Two development scenarios for the year 2025 are evaluated on the basis of four representative weeks. The first scenario focuses on the...

This article analyzes the effect of migration from a less advanced economy to a more advanced economy on economic growth. The analysis is performed in a two-country growth model with endogenous fertility, in which congestion diseconomies are incorporated. The model shows that out-migration...

Recent empirical work has suggested that there is an important distinction between short-run versus long-run scheduling behaviour of commuters, reflected in differences in values of time and schedule delays, as well as in preferred arrival moments, for the short-run versus the long-run problem....

Truck drayage in container ports faces several challenges. Due to the ongoing growth of container ship sizes, there are increasingly high peak situations in landside container handling at logistic nodes in the port, e.g. container terminals, empty depots, freight stations. In combination with...

Purpose: The objective of the research was aimed at achieving the implementation of the theory of constraints on the operating conditions of a hotel, which differs by its characteristics of traditional processes that have applied this method, from the great heterogeneity of resources needed to...
