Expectations,network effects and timing of technology adoption: some empirical evidence from a sample of SMEs in Italy

We provide evidence on the influence of expectations and network effects on the timing of technological adoption. By considering a sample of SMEs operating in Italy, we focus on the determinants of their decision to adopt Fast Ethernet, a communication standard for Local Area Networks (LANs). We find that both expectations and network effects significantly affect the timing of adoption. In particular, price expectations generally tend to delay adoption and (indirect) network effects in the form of backward compatibility as well as informational spillovers tend to foster adoption. Firm size also matters.

The Elasticity of Poverty with respect to Sectoral Growth in Africa

The African continent has grown by more than 4 percent yearly on average during the past decade. However, the link between this remarkable growth rate and poverty reduction is neither obvious nor simple. This paper focuses on the elasticity of poverty with respect to GDP growth at the sectoral level and takes into account the fact that economic growth may affect poverty directly as well as indirectly through sectoral labor share intensity. It develops a methodology that sheds light on the contribution of sectoral growth to poverty reduction country‐by‐country in Africa, guiding policy recommendations. As the composition of growth matters at least as much as its overall intensity, it is key to identify the sectors that have the strongest impact on poverty reduction and unleash their potential; if growth happens to concentrate in sectors with scarce pro‐poor potential, like commodity‐driven growth, redistributive strategies are necessary to compensate the weak effect on poverty.     

Consumer welfare from publicly supplemented private goods: age and income effects on demand for health care

In spite of major advances in the theoretical, positive and normative, literature analysing the welfare implications of public provision of private goods, empirical investigation is often limited to contingent valuation studies, for example, of health care programmes. In this article we argue that when a market for a (subsidised or free of charge) publicly provided good exists, a consumer demand approach can be used to construct a money metric of welfare corresponding to the consumption of public provision. We illustrate this approach in investigating age and income effects on household demand for health care in Cyprus, where free public provision is not universal and those entitled to it often resort to private supplementation. Our findings suggest that the money metric of welfare, which consumers attach to free access to publicly provided health care, varies with age and to a lesser extent with household income.     

Euro area inflation persistence

This paper presents evidence on the lag between monetary policy actions and the response of inflation in the euro area as a whole as well as in some of its core countries, notably Germany, Italy and France. In line with previous findings for the US and the UK, results here show that it takes over a year before monetary policy actions have their maximum effect on inflation both in the euro area and in individual countries and that a lag of this length has existed in Europe at least since the collapse of the Bretton Woods system, despite the numerous changes in European monetary policy regime thereafter. Results based on alternative definitions of inflation persistence support these findings and indicate, if any, that transmission lags could be in fact much longer for individual countries and the euro area as a whole, although, at the country level, there is strong evidence over time of a drop in German inflation persistence and a sizeable shift in the mean of inflation – particularly in Italy and France. An examination based on results from this paper reveals that euro area inflation persistence could well be an intrinsic phenomenon rather than a ‘statistical fluke’ due to aggregation.This research was conducted during my visit at the European Central Bank Directorate Research, as part of the Research Visitor Programme. I would like to thank Anna Maria Agresti for providing individual country data from the macroeconomic database of the Monetary Transmission Network; Alistair Dieppe for providing data from the ECB area-wide model dataset; and Michele Manna for supplying me with the area-wide M3 data for the period 1970–1980. I thank Gabriel Fagan, Frank Smets, Ignazio Angeloni, Vítor Gaspar, Michael Ehrmann, Guenter Coenen, Oreste Tristani, Tommaso Monacelli, Stephanie Schmitt-Grohe and Gerhard Ruenstler for helpful discussions during my stay at the ECB. I would also like to thank seminar participants at the ECB for their input and I am very grateful to Jeffrey Fuhrer, Edward Nelson and Kenneth West, Bernd Fitzenberger and two anonymous referees for comments on an earlier draft.

The impact of a ‘soda tax’ on prices: evidence from French micro data

Based on an original data set of more than 500,000 non-alcoholic beverage price records, we evaluate the impact on consumer prices of the ‘soda tax’, an excise on drinks with added sugar or sweetener, introduced in France in January 2012. We adopt a difference in differences approach and find that the tax was gradually passed through to the prices of the taxed beverages. After 6 months of its introduction, it was fully shifted to soda prices and almost fully shifted to the prices of fruit drinks, while the pass-through for flavoured waters was incomplete. We also find that the pass-through was heterogeneous across brands and retail groups.     

RESEARCH NETWORKS AS INFRASTRUCTURE FOR KNOWLEDGE DIFFUSION IN EUROPEAN REGIONS

This paper concentrates on the role of research network infrastructure in fostering the dissemination of innovation-related knowledge. It examines the structure of collaborative networks and of knowledge transfer between research, innovation and deployment activities in the field of information and communication technology for the European Union as a whole and for several European regions. Research networks complement diffusion networks by providing additional links and by increasing the number of the organisations involved in sharing and exchanging knowledge. Two types of actors are key players in these networks: hubs and gatekeepers. Hubs maintain the bulk of ties in the networks also helping the smaller and more isolated members remain connected. Gatekeepers bridge research and diffusion networks. Such organisations naturally offer greater policy leverage in establishing a European knowledge infrastructure. Moreover, strengthened inter-network connectivity among research and diffusion activities (deployment) would raise the effectiveness of European research in terms of accelerating innovation.     

The adoption of Web 2.0 services: An empirical investigation

The paper investigates the factors associated with the intensity of use of three Web 2.0 services - video sharing, social networking and social bookmarking - by looking at the users' characteristics and at the technological features. It relies upon a theoretical framework that combines the diffusion of innovation model with the technology acceptance model. However, it goes beyond them by focusing not simply on the determinants of adoption, but on the determinants of the intensity of use, and by introducing variables related to the social influence. The empirical analysis is based upon a survey of 300 users of Web 2.0 services. We find that the compatibility with users' needs and behaviours plays an important role for the intensity of usage of both video sharing and social networking services, while the ease of use positively affects the intensity of usage of social networking services, but has a negative effect on the intensity of usage of video sharing services. Extrinsic job-related motivations are important drivers of the intensive usage of social bookmarking and social networking services, while sharing contents is relevant for video sharing and social networking services. Finally, individual characteristics such as age, education and IT endowment also play an important role.
