A Simple Cross-Country Index of Trade Specialization

We propose a cross-country specialization index - the B ^⋆ - defined as the share of a given product in total country’s exports “normalized” by the average share across all countries. This indicator draws from the Revealed Comparative Advantage index suggested by Balassa (Manch Sch Econ Soc Stud 33(2):99–123, 1965), but its dynamic and cardinal properties are more suitable to perform a cross-country analysis over time. This feature is illustrated with a simple two-country by two-product stylized example and complemented with empirical evidence derived from 79 countries/groups of countries and four distinct technological sectors since the late sixties. We also provide empirical evidence on the external shape of the distribution of the B ^⋆ and on its intra-distribution dynamics in different technological sectors. The results indicate that the overall degree of specialization is higher for high-tech exports than for low-tech exports. From a dynamic point of view, there is evidence of significant persistence of the cross-country export patterns.     

Omnichannel approach: Factors affecting consumer acceptance

Abstract

The omnichannel approach is a new commercial opportunity that aims to offer consumers a unique and satisfying experience through any touch point. This research aims to understand the factors that might lead consumers to accept and use this new approach. The conceptual model was tested empirically using primary data collected from 210 Portuguese participants. The results reported suggest that perceptions of usefulness, ease of use, and compatibility have a positive effect on brand experience, which strongly affects the behavioral intention to use. Additionally, a moderation analysis, using user status as a moderator, shows that while usefulness is important to uniquely explain use intention for low frequency, ease of use is only a good predictor of use intention for high-frequency users. This research provides useful insights for academic research by shedding light on this new phenomenon, and simultaneously for businesses by deriving some implications for defining their omnichannel strategies.     

Assessing the nonlinear nature of the effects of R&D intensity on growth of SMEs: a dynamic panel data approach

Based on a sample of Portuguese SMEs for the period 1999–2006 and using two step estimation, namely probit regressions and dynamic estimators, this study makes two important contributions to the literature: (i) identification of a quadratic relationship between R&D intensity and SME growth that takes the form of a U, and so R&D intensity is a stimulating factor of SME growth for high levels of R&D intensity; being a restrictive factor of SME growth for low levels of R&D intensity; and (ii) the growth of SMEs seems to be dependent on the nonlinear effects associated with distinct levels of R&D intensity. The nonlinear effects identified suggest that Portuguese SMEs with high levels of R&D intensity more easily find an efficiency scale and are more dependent on internal financing and short-term debt as sources for funding growth, compared to the case of Portuguese SMEs with lower levels of R&D intensity.     

SME growth in the service sector: A taxonomy combining life-cycle and resource-based theories

The approach to the life-cycle theory has been used as an analytical tool of the firms' growth. Several researchers argue that organisations move across several development stages where different problems are found resulting from different management styles and priorities, and resources. This research aims to develop an empirical taxonomy of small medium enterprise (SME) growth in the service sector based on life-cycle and resource-based theories. The data were submitted to bivariate and multivariate analyses to develop and test an empirical life-cycle model. It was possible to conclude that the firms could be clustered in three life-cycle stages. Some implications and future researches are addressed.     

The elusive character of fiscal sustainability

We assess the sustainability of public finances in OECD countries using unit root and cointegration analysis, controlling for endogenous breaks. Results deem fiscal sustainability as rather elusive since we find lack of cointegration – absence of sustainability – between government revenues and expenditures (except for Austria, Canada, France, Germany, Japan, Netherlands, Sweden and UK); improvements of the primary balance after worsening debt ratios only for Australia, Belgium, Germany, Ireland, Netherlands and the UK; and Granger causality from government debt to primary balances for 12 countries (suggesting Ricardian regimes).     

Who’s Who in Global Value Chains? A Weighted Network Approach

This paper represents global value chains (GVCs) as weighted networks of foreign value added in exports, which allows for the identification of the specific roles of countries and for the quantification of their relative importance over time. A major structural change occurred in the beginning of the century as GVCs steadily turned into global networks, amid an unprecedented growth of value-added flows and the rise of China as a major player. First-order network metrics highlight the vital but also distinct roles of Germany, the US, China and Japan in the international organisation of production. Germany is very relevant both as a user and as a supplier of foreign inputs, whilst the US acts mostly as a supplier of value added to other countries. Second-order properties of networks shed light on the complex architecture of GVCs, notably in terms of cyclical triangular relationships. Germany’s GVCs mostly root in direct relationships, whilst Japanese ones typically involve more than two countries.
