This paper analyses the direct and indirect trade volume and trade cost effects of uncertainty on international trade and economic welfare using a structural gravity framework for a panel of 97 developed and developing countries from 2000 to 2018. Our results suggest that an increase in unilateral uncertainty affects average trade costs in a heterogeneous manner, depending on whether the uncertainty originates from the importing or exporting country. Moreover, using a cross-sectional gravity approach, we show that an uncertainty shock directly reduces cross-border trade flows. The paper illustrates the suitability of the proposed modeling approach by means of two counterfactual scenario analyses in which we calculate the general equilibrium trade and welfare effects of uncertainty induced by the unexpected outcome of the Brexit referendum in 2016 and the outbreak of the COVID-19 pandemic in 2020.

This paper investigates the relationship between the use of service inputs and integration in global value chains. Using macro and detailed firm-level data (for 1990–2017), the study documents the extent of India’s integration into global value chains. Older, larger, and more productive firms and firms with a higher leverage ratio are more likely to be deeply integrated into global value chains. Firms in the information technology services and electronics industry are more deeply integrated into global value chains, compared with textiles. Services are the engine for many global value chain industries as they help coordinate the different stages of production across geographical locations. The findings suggest that both the intensity of service usage as well as the composition or type of service used are important. Firms using service inputs, particularly complex services and information technology and information technology–enabling services intensively are typically more deeply integrated into global value chains.

This paper explores the relationship between the use of service inputs, participation in global value chains, and firm productivity. Services play the role of both an intermediate input in production and a coordinator. Using a detailed Indian firm-level data set from 1990–2017, the paper estimates the productivity premium associated with varying depths of global value chain integration and different intensities and types of services used in the production. The study finds that firms in global value chains have a productivity premium between 13 and 22 percent relative to domestic firms, with some variation based on the depth of global value chain integration and the sector to which the firm belongs. Both the type of service inputs used (composition of services) and the origin of services (whether sourced domestically or from abroad) matter for firm performance. While higher aggregate service input use (as captured by the share of expenditure on service inputs) is not necessarily associated with an increase in productivity, increased use of complex services and information technology services is associated with higher productivity. The use of imported services is associated with higher productivity. Moreover, firms that are more deeply integrated in global value chains benefit more from importing services.

This introduction elaborates how the relationship between religion and light can and should be addressed as a key theme for the critical study of religion. It synthesizes the principal arguments of the six articles collected in this special journal issue and locates them in a broader theoretical framework, focussing especially on the politics of knowledge production.

Understanding religion from a material and corporeal angle, this book addresses the ways in which refugees practice their religions and convert or develop new faiths. It also evaluates how secular institutions in Europe frame and determine what is classified as religion according to the law, and delineate the limits of religious authority, religious practice, and religious speech. The question of nationalism and migration has been shaping the political landscape in Europe for more than a decade, resulting in a nationalist upsurge. This volume places the current trajectories of people from Asia and Africa who flee from conditions such as oppression and conflict, and who are seeking refuge in Europe in a broader historical and comparative perspective. In so doing, it addresses past experiences in Europe with the role of religion in both producing and accommodating refugees, in the aftermath of the Peace of Westphalia, World War II, and in the context of the Cold War.

Global Value Chains (GVCs) provide an important opportunity to become member of the global economy. Gaining access to GVCs and the possibility of developing linkages with major suppliers and customers enables the prospect to upgrade products and production processes via knowledge and technological spillovers, learning by doing and the allocation of new task. Adopting new production technologies and realizing synergy effects might allow cost reduction, product innovation and product upgrading. Even if GVCs represent a rich environment for innovation activities, the extent to which knowledge is created and transferred among firms may vary considerably across their mode of participation in the global chain, thus resulting in heterogeneous innovation capacities for the firms involved. Differences in the forms of governance underlying buyer-supplier relationships - for instance linked to dissimilar power asymmetries and firm capability - can strongly affect the knowledge transmission along the chains and are potentially able to explain heterogeneities in firms' innovation propensity. Using a firm-product-level dataset of Indian manufacturing firms including information on business groups, this paper contributes to recent studies on international production and GVCs by testing the effect of different modes of internationalization on firms' upgrading activities, including the extensive and intensive margins of innovation and R&D expenditures. Controlling for the selection bias associated with the chosen mode of internationalization and accounting for potential reverse causality, this paper shows that the deeper firms are integrated internationally, the higher the likelihood that they engage in innovation activities. Firms which have a high mode of internationalization are not only more productive, but also more likely to introduce new products, upgrade existing products and produce more sophisticated products than firms that are less engaged in international markets and, thus, less prone to international competition.
