Assessing long-term fiscal developments: A new approach

We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spending and revenue - responsiveness and persistence -, a feature not captured by automatic stabilisers, we are able to infer about the sources of fiscal deterioration (improvement). Drawing on quarterly data, we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Square method for eight European Union countries plus the US. The results suggest that significant changes in the fiscal stance (including those related to the current crisis) are reflected in the estimates of persistence and responsiveness.     

The effect of nominal exchange rate volatility on real macroeconomic performance in the CEE countries

This paper analyzes the relation between nominal exchange rate volatility and several macroeconomic variables, namely real output growth, excess credit, foreign direct investment (FDI) and the current account balance, in the Central and Eastern European EU member states. Using panel estimations for the period between 1995 and 2008, we find that lower exchange rate volatility is associated with higher growth, higher stocks of FDI, higher current account deficits, and higher excess credit. At the same time, the recent evidence seems to suggest that following the global financial crisis, “hard peg” countries may have experienced a more severe adjustment process than “floaters”. The results are economically and statistically significant and robust.     

On negative time preferences

Survey data show that subjects positively discount both gains and losses but discount gains more heavily than losses. This holds for monetary and non-monetary outcomes. These results do not confirm the findings of two earlier studies about negative time preferences for non-monetary outcomes.     

Cost Savings From Generation and Distribution with an Application to Italian Electric Utilities*

In the last decade, the European Commission promoted a new regulatory framework aiming at a gradual liberalization of the energy markets. The introduction of competition among generators implies the need to separate generation from transmission and distribution activities. However, if savings can be reached by operating at different stages, vertical separation would increase the costs of providing power. This paper tests for the presence of economies from vertical integration on a sample of Italian local electric utilities and finds evidence of both multi-stage economies of scale and vertical economies. Even if the hypothesis of global subadditivity is not supported, our evidence suggests that a complete divestiture policy would entail efficiency losses. *For helpful comments and discussions, we thank two anonymous referees, Graziano Abrate, Bruno Bosco, Diego Piacentino, and participants at the 31st Annual Conference of the European Association for Research in Industrial Economics (EARIE), Berlin, Germany, 2–5 September, 2004, the 60th Congress of the International Institute of Public Finance (IIPF), Milan, Italy, 23–26 August, 2004, and seminars held at the Bocconi University, University of Lecce, University of Naples, University of Pavia, and University of Turin, where earlier versions of this paper were presented.

Impacts of the Arab Spring on trade in airline services

This article examines the impacts of the ‘Arab Spring’ on trade in air services between the various North African and Levant countries involved. Studies of the implications of these socio-economic changes on trade in the region are made difficult because of a paucity of good economic data and the involvement of outside countries in the trade that now takes place. The number of international airline seats available provides a partial and fairly reliable variable to examine trade patterns. The analysis looks at changes in patterns of trade in these services between 1997 and 2013.     

Innovation adoption and training activities in SMEs

This article adopts the resource-based view and the complementarities approach to examine how small and medium enterprises (SMEs) combine the adoption of organisational and technological innovation with investments in training activities. The results of econometric analysis on a panel data-set of about 118 Italian manufacturing SMEs furnish a quite complex picture of the effects of innovation on training. On the one hand, organisational innovation seems to be related to higher investments in (formal and informal) internal training; specifically, it is the adoption of autonomous teams and multi-skilling practices that is associated with the coverage and the intensity of internal training, whereas job rotation is negatively associated with the coverage of external training. On the other hand, the general index of technological innovation does not show any significant relationship with training activities, whereas the individual technological innovation variables are associated with internal training. Specifically, the coverage of internal training is positively affected by ICT innovation and negatively affected by process innovation. These results demonstrate that SMEs have limited awareness of the risks associated with underinvesting in training during the implementation phase of the innovation process. The implications of such findings for research and practice are discussed.     

Discretionary Government Consumption, Private Domestic Demand, and Crisis Episodes

This paper analyzes the dynamic impact of discretionary government consumption purchases on private demand. Using a panel of 132 countries from 1960 to 2008, we find that while discretionary changes in government consumption lead to crowding-in effects in the short run, crowding-out effects take over in the medium run. In addition, we also find that both short-term crowding-in and medium-term crowding out effects are amplified once we control for periods of crisis.     

Quantifying the Impact of Scientific Research on Agriculture

With the growing importance of science and innovation for farming, the scope for summary monetary estimates of the impact of agricultural research on productivity suggests internal rates of return of between 7 and 15 per cent, and time lags in maximum impact of around nine years. However, the extent to which the transmission process can be regarded as a ‘black box’ for econometric purposes is considered increasingly inappropriate, since the intermediate steps between research and the impacts of resulting technology adoption are increasingly complex and involve growing numbers of actors, actions and a wider set of policy objectives. Significant difficulties are encountered in quantifying research impacts, including gaps in data for dependent and explanatory variables. New features of the agricultural sector also need to be accounted for, which relate to the role of knowledge engineering, globalisation and the establishment of new impact pathways which are affecting the speed of transmission of innovations. Public support for agricultural research funding is generally justified but returns are not sufficiently high, thus requiring careful reflection on priorities for research investment. Combined use of qualitative and quantitative evaluation approaches can be complementary and more effective than relying on either alone.     

Country size and business cycle volatility: Scale really matters

In a recent study Andrew Rose found that country size does not matter for several economic outcomes [Rose, A.K., 2006. Size really doesn't matter: In search of a national scale effect. J. Japanese Int. Economies 4, 482–507]. However, he did not consider the effect that country size may have on business-cycle volatility. To investigate the empirical relationship between business cycle volatility and country size, we use a panel data set that includes 167 countries from 1960 to 2000. The results suggest very strongly that the relationship between country size and business cycle volatility is negative and statistically significant. This implies that smaller countries are subject to more volatile business cycles than larger countries. This holds both in a simple bivariate model and when we include Rose's control variables and openness. Moreover, the results are robust to different sample periods and several detrending methods. It follows that country size really matters, at least in terms of cyclical fluctuations. J. Japanese Int. Economies 21 (4) (2007) 424–434.
