Many improvements have been proposed for the basic gravity model specification, most of which are confirmed by standard statistical tests due to the large number of observations often used to estimate such models. We use Monte Carlo experiments to examine situations in which features of models...

The paper tabulates Myanmar's merchandise trade as reported by its partner countries, thereby circumventing the data constraints stemming from Myanmar's patchy trade records. It then estimates Myanmar's export potential, based on the bilateral export patterns observed for six other countries in...

Fragmentation of the global value chain makes it difficult to assess the effects of trade liberalization on the global pattern of production. Gross bilateral trade ows no longer reveal a country's or a sector's value added contribution. Yet, it is value added that matters for employment and...

In the 2000s, China's WTO entry constituted a major trade shock. In this paper, we analyze its eff ects on trade and value chains. The fragmentation of the global value chain makes it hard to disentangle who produces for whom. Value added trade contains this information. We build a multi-sector...

This paper aims to evaluate the trade potential of manufactured products between countries belonging to the EU in the threshold of its Eastern enlargement. For this purpose we use a Gravity model which is estimated with a Poisson Pseudo-Maximum Likelihood Method. We extend the specification of...

Epidemiological models assume gravity-like interactions of individuals across space without microfoundations. We combine a simple epidemiological frame-work with a dynamic model of individual location choice. The model predicts that flows of people across space obey a structural gravity...

This paper investigates bilateral trade flows and the level of openness across ECOWAS-15 nations for the period of 1981-2013 using Poisson pseudo maximum likelihood (PPML), fully modified ordinary least squares (FMOLS) and canonical cointegrating regression (CCR). Comparing the results, the...

To what extent has trade liberalization contributed to global production fragmentation and the formation of production networks? We derive structural equations for value added trade flows, the domestic value added content of exports (DVA) and the value added exports to exports (VAX) ratio, as...

In the 1980s, six former southern republics of the USSR (Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan), like other former Soviet republics, traded very intensively both between themselves and with the other Soviet republics, but had a meagre volume of trade with...

This paper presents two empirical tools to quantify the impacts of tariff changes on bilateral trade and welfare. Both tools are rooted in the structural gravity literature. The first tool estimates the impact of tariff changes on bilateral trade for 5,020 products in a partial equilibrium...
