Trading activities,productivity and markups: Evidence for Spanish manufacturing

This work analyses the firms' internationalisation strategies of importing intermediates and exporting output, and the potential rewards of these activities in terms of total factor productivity (TFP), as a proxy for marginal costs, and markups. It further deepens into the study of the relationship between internationalisation strategies and markups by disentangling whether it operates through affecting firms' marginal costs and/or firms' prices. The panel database employed in this paper is the Spanish Survey on Business Strategies (ESEE) for the period 2006–14. Results in the paper distinguish between SMEs and large firms and indicate that there is high persistence in the performance of these activities and in firms' TFP and markups. For SMEs, we obtain rewards from importing inputs as well as exporting output in terms of TFP and markups. For large firms, we obtain rewards in TFP from the importing activity and rewards in markups from the exporting activity. Finally, we find evidence that the effects of internationalisation strategies on markups are due to both a price channel and a marginal cost channel.

On the heterogeneous short‐term effects of minimum wages on labor demand

A strand of the literature documents no effects or even positive effects of a higher minimum wage on employment. This evidence is frequently linked to the existence of monopsonistic labor markets or search frictions. However, empirical studies show that these findings could be related to a low short‐term minimum wage–employment elasticity in a competitive labor market. We show that mixed theoretical employment effects of a minimum wage policy can be predicted in the short term in assignment economies with price‐taker agents and no search frictions.     

Is the unemployment–inflation trade-off still alive in the Euro Area and its member countries? It seems so

The unemployment–inflation trade-off can be interpreted as a proposition concerning the response of these two variables to aggregate demand shocks. In this paper, we study the possible presence of the trade-off in the Euro Area and in a wide group of Euro-area countries in the last 20 years, that is, since the start of EMU. We use the structural VAR methodology that allows the separation between supply and demand shocks. Our main finding is that the existence of a trade-off is largely confirmed both at the Euro Area and at the national level. Nevertheless, the size of the trade-off, measured at different horizons, shows some heterogeneity among countries. No less important, when we augment the VAR model by introducing monetary policy in the context of an open economy, we find that monetary policy shocks push inflation and unemployment in opposite directions in the currency area. Another interesting result concerns the evidence of a relatively flat relation between unemployment and inflation, conditionally to monetary policy shocks. The bulk of these conclusions seem to be confirmed by a number of robustness checks.     

Agglomeration dynamics of innovative start-ups in Italy beyond the industrial district era

Building on the literature on agglomeration economies, this study examines how urbanization, industry-diversification, district economics and incubating initiatives are associated to the creation of innovative start-ups in Italy. The empirical analysis is based on a sample of 6018 innovative start-ups distributed across 104 Italian NUTS 3 regions. Our findings show that incubating initiative and industrial districts play a major role for new venture creation and provide support to the positive role of urbanization economies and industry specialization over diversification. Finally, we discuss future research directions grounded on the empirical evidence provided by our study.

Going multilateral? Financial markets' access and the League of Nations loans, 1923–8

Why are international financial institutions important? This article reassesses the role of the loans issued with the support of the League of Nations. These long‐term loans constituted the financial basis of the League's strategy to restore the productive basis of countries in central and eastern Europe in the aftermath of the First World War. In this article, it is argued that the League's loans accomplished the task for which they were conceived because they allowed countries in financial distress to access capital markets. The League adopted an innovative system of funds management and monitoring that ensured the compliance of borrowing countries with its programmes. Empirical evidence is provided to show that financial markets had a positive view of the League's role as an external, multilateral agent, solving the credibility problem of borrowing countries and allowing them to engage in economic and institutional reforms. This success was achieved despite the League's own lack of lending resources. It is also demonstrated that this multilateral solution performed better than the bilateral arrangements adopted by other governments in eastern Europe because of its lower borrowing and transaction costs.     

Antecedents of Purchase Intention in the Online Context

The understanding of the determinant factors of customer purchase intention is necessary, and it is equally important to study the online purchase context, since this context is disseminated among customers. A theoretical model has been elaborated on and tested, considering the constructs of information quality, distrust, and perceived risk as antecedents of purchase intention, and aiming to analyze the relationship among these constructs in the online purchase context. A quantitative research study has been performed by means of the application of a survey. Multivariate statistics techniques have been applied for data analyses, including structural equation modeling. This study contributes to the evolution of the empirically tested concepts by providing a greater individual understanding of each construct presented in the theoretical model, as well as the relationship among them as determinants of purchase intention; the indication is that meaningful relationships were found which may impact greater profitability and, consequently, greater competition for online retailers.     

Direct and Spillover Effects of Unconventional Monetary and Exchange Rate Policies

This paper explores the direct effects and spillovers of unconventional monetary and exchange rate policies. We find that official purchases of foreign assets have a large positive effect on a country’s current account that diminishes considerably as capital mobility rises. There is an important additional effect through the lagged stock of official assets. Official purchases of domestic assets, or quantitative easing (QE), appear to have no significant effect on a country’s current account when capital mobility is high, but there is a modest positive impact when capital mobility is low. The effects of purchases of foreign assets spill over to other countries in proportion to their degree of international financial integration. We also find that increases in US bond yields are associated with increases in foreign bond yields and in stock prices, as well as with depreciations of foreign currencies, but that all of these effects are smaller on days of US unconventional monetary policy announcements. We develop a theoretical model that is broadly consistent with our empirical results and that highlights the potential usefulness of domestic unconventional policies as responses to the effects of foreign policies of a similar type.
