Explanations for the West's escape from premature mortality have focused on chronic malnutrition or income and on public health or state capacity. We argue that by ignoring the multigenerational effects of variance in ancestors' harvests, we are underestimating the contribution of modern...

The majority of global trade moves by sea through hub-and-spoke shipping networks. We investigate the returns to being a hub country by analyzing how transshipment activity shapes trade and supply chains. We show that most US imports especially from smaller origin countries are transshipped via...

This study analyzed the determinants of air cargo volumes between airports using an augmented gravity model. Data from 115 airport pairs in China spanning 2009-2020 were utilized. The findings reveal that economic disparity significantly influences air cargo volumes, with greater economic...

We examine how trade and policy uncertainty affect shipping freight rates, using a Bayesian Vector Autoregression (BVAR) model. Trade uncertainty has a strong effect on shipping costs, even though the effects become insignificant within a year. On the other hand, policy uncertainty has a...

The failure of newly independent Central Asian countries to diversify exports after the Soviet Union's collapse is attributed to high trade costs, either because these countries are landlocked or due to border delays and regulatory obstacles. This paper estimates the impact of the high costs of...

We propose a methodology to calculate the mismatch between places of work and places of residence that incorporates monetary and opportunity transportation costs while correcting for possible overestimation of job accessibility. This methodology enables the analysis of spatiotemporal changes in...

The pandemic and the last years' geopolitical disruptions have laid bare the vulnerability of Europe's supply chains, as well as the challenges posed by insecure oil and gas supplies. In this contribution, we aim to add to this debate by raising awareness of the vulnerability of trade and supply...

We propose and construct novel measures of the effectiveness and potential of trade blocs, combining estimation with granular data and simulation with a New Quantitative Trade Model. We deploy our methods and new indexes to quantify the potential benefits from (i) further integration within the...

We implement Pigovian transport pricing in a field experiment in urban agglomerations of Switzerland over the course of 8 weeks. Our pricing considers the external costs from climate damages, health outcomes from pollution, accidents and physical activity, and congestion. It varies across time,...

We develop a spatial dynamic general equilibrium model of a small open agricultural economy to study the impact of global food, fuel and fertilizer price shocks on consumption patterns of heterogeneous households located in different regions, under alternative fiscal responses, including direct...

Background: Indonesia is an archipelagic country with 17,508 islands spread over the Pacific and Indian Oceans, with thousands of inter-island routes requiring a large and engaged fleet. The vast expanse of the country also leads to challenges related to optimal fleet coverage, routing, and oil...

Background: Despite concerted research efforts, the collection of domestic waste remains poorly understood in terms of financial and environmental cost drivers. Detailed studies of specific systems, yielding limited broader understanding, remain the norm. Methods: This study presents flexible...

Explanations for the West's escape from premature mortality have focused on chronic malnutrition or income and on public health or state capacity. We argue that by ignoring the multigenerational effects of variance in ancestors' harvests, we are underestimating the contribution of modern...

We study the impact of transport-induced agglomeration on workers' earnings, as well as the productivity and costs of establishments, in the capital region of Finland using comprehensive individual- and establishment-level registry data. To our knowledge, we are the first to jointly examine...

We separate the effects of market power and capacity constraints in transportation. A simple model shows imperfect competition - not capacity constraints - generates differential freight price changes across buyers following a demand shock. Consistent with this, difference-in-differences...

It is well established that climate change affects productivity, but its effects on trade costs have not been studied. I combine international trade and weather data covering 190 years. I use an augmented gravity framework to show that rising temperatures at the origin or destination country...

Transportation infrastructure is vital for the smooth functioning of international trade. Ports are a crucial gateway to this system: with more than 80% of trade carried by ships, they shape trade costs, and it is critical that they operate efficiently. Yet ports are susceptible to disruptions,...

While the relationship among land price, transportation cost, and urban sprawl under the condition of local governments monopolizing land supply has been rarely discussed in the literature, this paper addresses this gap by hypothesizing based on the monocentric city model. The hypothesis...

This paper estimates a synthetic difference-in-differences specification on the roll-out of a program providing free bus transit for women in several Indian states, to examine the impact on women's time allocation and labor supply. Household expenditures on buses fall and women save time on...

We present a new model for estimating the distribution of international freight transport over transport modes that is directly applicable to aggregated data, allows estimations and predictions also when some modes are infeasible on some routes, and requires few processing time and memory space....

Intermodality is regarded as one way of achieving more sustainable transport solutions. To make intermodal transport the preferred solution among shippers, it must be attractive according to the concept of generalized transport costs. An extended model for generalized transport costs is...

We develop a structural framework that allows us to quantify the evolution of aggregate bilateral trade costs and markups over time. With minimal assumptions, we can disentangle aggregate markup and trade cost changes from observed changes in trade flows. We apply our method to trade data...

We investigate how the frequent flooding that damaged the internal transport infrastructure in late 19th and early 20th colonial Jamaica affected local economies. To this end the evolution of the road and railways transport system was geo-referenced and combined with geo-localized damaging flood...

We investigate the effect of domestic armed violence brought about by insecurity on the geography of freight mobility and the resulting differential access of regions to global markets. There is a preponderance of evidence from the micro-level analysis of Colombia-U.S. export shipping records...

The gravity model, which is applied to international trade, explains the conceptual models of international business. It has been used in various areas of the global economy, such as trade, foreign direct investment, and even the determinants of tourist demand at the level of countries and...

This study investigates how transportation costs and environmental damage affect social welfare and the optimal degree of nationalization by assuming asymmetric mixed oligopoly markets. It assumes that both transportation costs and environmental damage are incurred when products are transported...

We implement Pigovian transport pricing in a field experiment in urban agglomerations of Switzerland over the course of 8 weeks. The pricing considers external costs from climate damages, health outcomes and congestion and varies across time, space and mode of transport. The treatment reduces...
