    Abstract A worldwide event like the 2020 Coronavirus outbreak can only reinforce the interest in modelling trade diversification as a key factor in countries' vulnerability to external shocks. This paper adopts a detailed relative framework to study the determinants of product-level export variety in a large bilateral panel of developing and developed economies (16,770 country pairs in the period 1988-2014). We find that country pairs characterized by large differentials in productivity and in the makeup of the labour force differ in export variety patterns. This result holds after controlling for other endowments and for trade costs. Further, productivity plays a significant role in the reduction of export variety dissimilarities between countries belonging to different income groups. Hence, without successful technological convergence the low-income economies will not be able to reduce their exposure to export risk.

    Abstract This paper compares two alternative growth paths, assessing the effects on productivity of specialisation in natural resources (NR) and in technologically advanced products. The empirical analysis exploits product-level export data for 109 developing and 51 developed economies over the period 1996-2018. We document two distinct types of specialisation, based on exports either of natural resources or of technological products, and compare their role in productivity growth by GMM estimation of a conditional convergence model. In general, reliance on natural resource exports slows growth, but we find that the type of resources exported is important: fuel exports hamper growth while specialisation in metals enhances the catch-up in productivity. Technological specialisation, especially in products typical of the Fourth Industrial Revolution, reinforces productivity growth but does not affect the relationship between resources and productivity growth.

    Abstract This paper models export diversification in the context of an abundance of natural resources by decomposing the relative Theil index. On a sample of 160 countries from 1996 to 2018 we document that 74% of the high export concentration typical of the initial stage of development is driven by the limited variety of products other than natural resources. Later, the component representing export reallocation between resources and non-resource products gains importance, and eventually, together with intra-resource heterogeneity, explains the entire amount of export diversification at high income levels. Our estimates show that natural resource abundance (in particular of fossil fuels) impedes overall diversification, limiting the variety of non-resource exports and hampering restructuring towards technologically advanced exports. However, once size and productivity differences across countries are taken into account, the effect of resource abundance on export diversification is weak.

    Abstract This paper uses a sample of over 9.5 million workers from 22 European countries to study the intertwined effects of digital technology and cross-border production links on workers' wellbeing. We compare the social effects of technological change exhibited by three types of innovation: computerisation (software), automation (robots) and artificial intelligence (AI). To fully quantify work-related wellbeing, we propose a new methodology that corrects the information on remuneration by reference to such non-monetary factors as the work environment (physical and social), career development prospects, or work intensity. We show that workers' wellbeing depends on the type of technological exposure. Employees in occupations with high software or robots content face worse working conditions than those exposed to AI. The impact of digitalisation on working conditions depends on participation in global production. To demonstrate this, we estimate a set of augmented models for determination of working conditions, interacting technological factors with Global Value Chain participation. GVC intensification is accompanied by deteriorating working conditions - but only in occupations exposed to robots or software, not in AI-intensive jobs. In other words, we find that AI technologies differ from previous waves of technological progress - also in their impact on workers' wellbeing within global production structures.

    Abstract The purpose of this paper is to evaluate the role of trade in productivity growth in a sample of 30 sectors in 25 EU countries in the period of rapid East-West integration. Shift-share analysis is used to show that changes in value added per hour worked in these countries appear to be mainly due to positive developments (rising productivity) within single industries and only to a lower extent result from a shift towards higher productivity activities. Trade is found to be an important positive determinant of intra-industry productivity growth in European countries. Exports and imports alike can be associated with efficiency gains, but intermediate good exchange and trade with New Member States exert a particularly strong influence on intra-industry productivity growth in the EU.

    Abstract This paper presents empirical evidence on the diversification process concerning Polish exports (1994-2010), compared to European and global samples of countries. It analyzes both the commodity structure of Polish trade and the geographical diversification of Poland's trading partners. The analysis draws on highly disaggregated data on exports (HS 6digit) and combines descriptive analysis with non-parametric, semi-parametric and parametric estimation models. The results suggest that Poland (exporting 84% of all goods present in the sample) can be placed among countries with well-diversified export products. In terms of geographical diversification, Poland exploits approximately one-fifth of its theoretical overall market reach potential (the best score among new member states) and the diversification of its partner countries increased in the period analyzed. The Polish export portfolio, in terms of the variety of both its products and receiving markets, is more diversified than what is typical for countries at approximately the same stage of economic development.

    Abstract The paper presents the dynamics of trade diversity with respect to stages of development in the European context. The analysis focuses on EU27 countries observed across the years 1988-2010 and compared to a sample of 136 international economies at all levels of income per capita. We use product level statistics (six digit HS0) and confront export and import patterns of absolute diversification/concentration. The results show that in line with 'stages of diversification' approach (Imbs and Wacziarg, 2003), EU27 countries are characterized by high degree of trade diversity (on average, EU27 countries export 78% and import 90% of goods effectively exported and imported at the world level) and within the analyzed period most of them registered a reconcentration of trade structures. Obtained estimation results confirm positive relationship between trade diversity and economic development levels (conditional mainly upon the size of the country) with a possibility of reconcentration at higher stages of development (observable in nonparametric estimates).
