Pro-competitive reforms and timing of implementation: An IGEM-based simulation analysis for Italy
No full textGHG Emissions Control and Monetary Policy
No full textThis paper examines the optimal environmental and monetary policy mix in a New Keynesian model embodying pollutant emissions, abatement technology and environmental damage. The optimal response of the economy to productivity shocks is shown to depend crucially on the instruments policy makers have available, the intensity of the distortions they have to address (i.e. imperfect competition, costly price adjustment and negative environmental externality) and the way they interact
Climate actions, market beliefs, and monetary policy
No full textThis paper studies the role of expectations and monetary policy in the economy's response to climate actions. We show that in a stochastic environment, without the standard assumption of the perfect rationality of agents, there is more uncertainty regarding the path and the economic impact of a climate policy, with a potential threat to the ability of central banks to maintain price stability. Market beliefs and behavioral agents increase the trade-offs inherent to the chosen mitigation tool, with a carbon tax entailing more emissions uncertainty than in a rational expectations model and a cap-and-trade scheme implying a more pronounced pressure on allowance prices and inflation. The impact on price stability is worsened by delays in the implementation of stringent climate policies, the lack of confidence in the ability of central banks to keep inflation under control, and the adoption of monetary rules tied to expectations rather than current macroeconomic conditions. Central banks can implement successful stabilization policies that reduce the uncertainty surrounding the impact of climate actions and support the greening process while remaining within their mandate
Environmental policy and macroeconomic dynamics in a new Keynesian model
No full textThis paper studies the dynamic behaviour of an economy under different environmental policy regimes in a New Keynesian model with nominal and real uncertainty. We find the following results: (i) an emissions cap policy is likely to dampen macroeconomic fluctuations; (ii) staggered price adjustment alters significantly the performance of the environmental policy regime put in place; (iii) the optimal environmental policy response to shocks is strongly influenced by the degree to which prices adjust and by the monetary policy reaction
Structural reforms and the potential effects on the Italian economy
No full textSince the second half of 2011, after a period of prolonged low growth, Italy has found itself at the center of a severe economic crisis. Concerns about the sustainability of its debt burden, along with gloomy growth prospects, have pushed up the cost of government borrowing, exacerbating current economic conditions. At the moment Italy is facing two mounting economic challenges: (i) achieve a rapid fiscal consolidation to restore financial market confidence; (ii) implement structural reforms to strengthen medium-term growth prospects. Using the European Commission's model QUEST III with R&D, adapted to Italy, we quantify the potential effects of a set of interventions inspired to the reform packages currently being undertaken or under discussion and consider different levels of policy effort. Results show that reforms are likely to bring about sizable gains in output, consumption, employment and net foreign assets position and that most of these gains derive from labor market reforms. However, the fiscal austerity plan is likely to severely mitigate the positive effects of the interventions, especially during the earlier phases of the reform process. Most of these losses accrue to liquidity-constraint households who would experience a drop in consumption
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Environmental regulation, firm heterogeneity and macroeconomic volatility
Full text linkWe expand a conventional Real Business Cycle (RBC) model incorporating environmental
regulation and heterogeneous firms in order to investigate the interrelationships between
firm heterogeneity, environmental policy, and economic uncertainty. The findings are as
follows: First, the impact of the environmental regulation on macroeconomic volatility
is significantly influenced by the source of business-cycle variation. Second, firm hetero-
geneity has relevant implications for macroeconomic volatility, regardless of the origin of
the macroeconomic shock. Finally, the dynamics of the distribution of capital stocks and
productivity across productive plants cause the aggregate reaction to the stricter environ-
mental policy to be nonlinear, implying a different macroeconomic adjustment than the
analogous Representative agent counterpart. The key micro-parameters are estimated
consistently with data of regulated firms under the EU Emissions Trading System (EU
ETS)
