Road Infrastructure

We examine the contribution of domestic and interstates road infrastructures to trade flow between member countries of the Central African Economic and Monetary Community (CEMAC). Theories of international economics as well as those of the new economic geography suggest a positive contribution of both road infrastructures to intraregional trade. A gravity model of international trade is estimated to evaluate this theoretical prediction in the CEMAC zone. Results confirm a positive contribution of interstate road infrastructure to intra-Community trade, but show no evidence of a positive contribution of domestic road infrastructure to intra- CEMAC trade.

International Trade Network

As a classical trade model, the gravity model plays an important role in the trade policy-making process. However, the effect of physical distance fails to capture the effects of globalization and even ignores the multilateral resistance of trade. Here, we propose a general model describing the effective distance of trade according to multilateral trade paths information and the structure of the trade flow network. Quantifying effective trade distance aims to identify the hidden resistance information from trade networks data, and then describe trade barriers. The results show that flow distance, hybrid by multi-path constraint, and international trade network contribute to the forecasting of trade flows. Meanwhile, we also analyze the role of flow distance in international trade from two perspectives of network science and econometric model. At the econometric model level, flow distance can collapse to the predicting results of geographic distance in the proper time lagging variable, which can also reflect that flow distance contains geographical factors. At the international trade network level, community structure detection by flow distances and flow space embedding instructed that the formation of international trade networks is the tradeoff of international specialization in the trade value chain and geographical aggregation. The methodology and results can be generalized to the study of all kinds of product trade systems.

The paper reviews Paul Krugman’s contributions that earned him Nobel Prize in Economics of 2008 and grounded two fields of economic theory — new theory of international trade and new economic geography. The paper shows how the assumption of internal increasing returns to scale and monopolistic competition borrowed by Krugman from the industrial organization theory changed the conclusions of standard models and enriched our understanding of international trade and spatial distribution of economic activity.

Originating from Newton’s gravitational theory which was posed in 1687; the concept of gravity equation was primarily used by Tinbergen in the field of international trade analysis in 1962. After Tinbergen, Pöyhönen, Linnemann, Anderson, Santos and Tenreyro, Bergstrand and Egger, Deardorff and also Wooldridge developed the theory of gravity. And gravity model has become progressively well-liked in the academic publications. The aim of this study is to determine the literature belonging to the years between 1980 which is the starting point for “gravity” related studies’ being published on Web of Science (WoS) and Scopus and 2020 to execute a bibliometric review of this literature. Thereby, it targets to supply a perspective concerning the nature of the studies executed on the subject of gravity model, so as to point out the lack of the bibliometric analysis-using studies on the field of international trade. In this study, we collected the data between 1980-2020 from Scopus and Web of Science database and analysed using the Gephi, Vosviewer and R Studio programmes in order to be used in our bibliometric analysis. The results showed that U.S.A., Germany and China are the countries which have the highest number of publications in this field, and the journals with the highest number of publications are “World Economy”, “Journal of International Economics” and “Review of International Economics”. The fact that three programmes have been simultaneously used in the study is demonstrative of the originality of the paper.

Η παρούσα διατριβή είναι μια συλλογή από δύο ανεξάρτητες μελέτες που συνεισφέρουν στον τομέα της Νέας Οικονομικής Γεωγραφίας και του Διεθνούς Εμπορίου. Η πρώτη μελέτη δείχνει ότι η γεωγραφική συσσώρευση των παραγωγικών συσντελεστών μέσα σε ένα σύστημα χωρών προέρχεται από το γεγονός ότι το εξωτερικό είναι πιο σημαντικό σε σχέση με την εγχώρια χώρα. Η δεύτερη μελέτη δείχνει ότι υπό τους ευέλικτους μισθούς, η βελτίωση της παραγωγικότητας μιας χώρας ωφελεί τον εμπορικό της εταίρο. Επιπλέον, αποδεικνύεται ότι η βελτίωση της παραγωγικότητας μιας αναπτυσσόμενης χώρας ωφελεί το σύνολοτης οικονομία. Ωστόσο, τα αποτελέσματα διαφέρουν όσον αφορά στον εμπορικό της εταίρο, αφού κάποιες ομάδες επηρεάζονται θετικά και κάποιες αρνητικά. Η τρέχουσα διδακτορική διατριβή απεικονίζει και ρίχνει φως στον ρόλο ορισμένων θεμελιωδών γνώσεων στον τομέα της Νέας Οικονομικής Γεωγραφίας και τών μοντέλων διεθνούς εμπορίου, γενικά.
