This 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. • This work investigates how expectations can shape a green transition. • Without fully rational agents impacts of climate policy are more uncertain. • Carbon taxes and cap-and-trade's drawbacks are enlarged by non-fully-rational agents. • Delayed action and low credibility in central banks cause major inflationary pressure. • A reactive monetary policy can reduce uncertainty on climate policies' impacts.

Abstract: Since 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. [Copyright &y& Elsevier]

In this paper we develop two simple discrete-time Ramsey models augmented with migrant workers to assess the impact of migration on per-capita domestic consumption. In one model we assume perfect substitutability between migrants and natives while in a second model we explore the effect of migration in the case of imperfect substitutability. We find that migration unambiguously rises per-capita domestic consumption growth in the case of perfect substitutability in the short as well as in the long run, while in the case of imperfect substitutability migration increases the long-run per-capita domestic consumption only if production is 'sufficiently' reactive to capital changes. Our findings are partially in contrast to similar analyses developed in continuous time (in particular those of Hazari and Sgro (2003) and Moy and Yip (2006)). [ABSTRACT FROM AUTHOR]
