This analysis employs cointegration methods and semiparametric regression in order to assess the integration of maize markets and the factors determining national and cross-national transmission of price signals in Sub-Saharan Africa. We use a rich dataset of 16 series of wholesale maize prices...

We estimate the cost of transporting corn and the resulting degree of spatial differentiation among downstream firms that buy corn from upstream farmers and examine whether such differentiation softens competition enabling buyers to exert market power (defined as the ability to pay a price for...

Widespread market imperfections in agricultural value chains raise the possibility that regulatory interventions may enhance efficiency and farmers' welfare. We develop a structural model of agricultural value chains and estimate it using rich data from Costa Rica's coffee sector to evaluate...

Global value chains have fundamentally transformed international trade and development in recent decades. We use matched firm-level customs and manufacturing survey data, together with Input-Output tables for China, to examine how Chinese firms position themselves in global production lines and...

This paper investigates the impact of the Covid-19 pandemic on trade flows in the case of the European countries. First, an ARDL dynamic panel model is estimated using the PMG method to analyse monthly data covering the most recent period (2019M1-2021M12); then, the GMM and PCSE approaches are...

Between November 18th and 25th, 2020, 348,810 out of 500,607 (69.7 percent) eligible residents of the South Tyrol region of Italy volunteered to take a Covid-19 rapid antigen test. We examine the community characteristics that are associated with higher testing rates. Our findings point to a...

The Black Death killed 40% of Europe’s population between 1347-1352, making it one of the largest shocks in the history of mankind. Despite its historical importance, little is known about its spatial effects and the effects of pandemics more generally. Using a novel dataset that provides...
