The Macroeconomy After Tariffs
2021
AbstractWhat does the macroeconomy look like in the aftermath of tariff changes? This study estimates impulse response functions from local projections using a panel of annual data that spans 151 countries from 1963 to 2014. Tariff increases are associated with persistent, economically and statistically significant declines in domestic output and productivity, as well as higher unemployment and inequality, real exchange rate appreciation, and insignificant changes to the trade balance. Output and productivity impacts are magnified when tariffs rise during expansions and when they are imposed by more advanced or smaller (as opposed to developing or larger) economies; effects are asymmetric, …
Analisi degli effetti delle opzioni tariffarie regionali sull'ottimizzazione di μ-grids energetiche alimentate da impianti poligenerativi
2011
L'ottimizzazione di sistemi energetici complessi per la produzione e la distribuzione di fluidi caldi e freddi per utenti civili è un problema molto complesso; due possibili configurazioni possono essere prese in considerazione, ovvero le piccole unità singole per singoli edifici ed i grandi impianti integrati con reti di teleriscaldamento. Affrontare un problema così complesso, che coinvolge un numero molto elevato di variabili, richiede algoritmi e tecniche di risoluzione efficienti. La ricerca svolta ha consentito di sviluppare nuovi metodi di mathematical programming, ed in particolare tecniche di Mixed Integer Linear Programming (MILP), per quanto concerne l’ottimizzazione di sistemi p…
Financial Measures for Supporting Wind Power Systems in Europe: A Comparison between Green Tags and Feed’in Tariffs
2008
Distributed Generation demonstrates to be able to significantly influence the electric power system, bringing considerable benefits to the quality of service and improving the energetic efficiency of the distribution network. In particular, in the last few years, Distributed Generation from renewable energy sources is considerably increased thanks to the many support policies promoted worldwide with the aim of facing the environmental issue and the problem of the permanent rise of prices of the fossil energy. In this contest, after a brief review on the financing strategies carried out in Europe in the last decade for promoting the recourse to renewable energy, the paper presents a comparis…
DEMAND Project: A Peak Load Shaving Strategy for End-User Consumers
2018
Battery energy storage systems (BESS) are becoming increasingly widespread in modern power systems, thanks to the important benefits they can provide to the electricity grid. Indeed, BESS can be used in time shifting applications, storing energy during off-peak periods and discharging during peak times (when the cost of electricity is high). When BESS are used for peak shaving purposes, they also contribute to relieve peak demand charges, thus ensuring a saving for the consumers. This paper describes a peak load shaving strategy defined within the DEMAND project. The strategy is able to guarantee the flattest daily power diagram and the maximum benefit for the electricity consumers, reducin…
Economic impact of Ice Thermal Energy Storage Systems in residential buildings in presence of double-tariffs contracts for electricity
2009
Thermal energy storage is one of the most important methods of demand-side load management, thanks to the capacity of reducing significantly the peak power demand for air conditioning in buildings. Thermal Energy Storage Systems (TESS) are indeed used for producing and storing cooling capacity during off-peak hours (in particular during night hours) to meet the following day's air conditioning requirements. The current paper presents a study on the effects of the installation of Ice TESS for cooling on the power daily profile of residential buildings, and examines the economic repercussions on the electricity billing. With reference to this second theme, the paper examines, in particular, t…
On Capturing Oil Rents with a National Excise Tax Revisited
2004
In this paper the scope of Bergstrom’s (1982) results is studied. Moreover, his analysis is extended assuming that extraction cost is directly related to accumulated extractions. For the case of a competitive market it is found that the optimal policy is a constant tariff if extraction is costless. However, with depletion effects, the optimal tariff must ultimately be decreasing. For the case of a monopolistic market the results depend crucially on the kind of strategies the importing country governments can play and on whether the monopolist chooses the price or extraction rate. For a price-setting monopolist it is shown that the importing countries cannot use a tariff to capture monopoly …
The new course of FITs mechanism for PV systems in Italy: novelties, strong points and criticalities
2011
The paper deals with the new course of the Feed-in Tariffs mechanism for photovoltaic systems that will start from January 1, 2011 in Italy with the actuation of the Government Decree DM 06/08/2010. After a short introduction on Feed-in Tariffs and Net-metering in Italy, the paper focuses the attention on an economical comparison between the incentives established by the Government Decree DM 19/02/07, ended on December 31, 2010 and those introduced by the DM 06/08/2010. The economical comparison is based on three indexes: the Pay Back Period, the Net Present Value and the Internal Rate of Return, characterizing the investments done for the realization of the photovoltaic systems. In particu…
Critical Assessment of Feed-In Tariffs and Solar Photovoltaic Development in Vietnam
2022
Vietnam became the world’s third largest market for solar photovoltaic energy in 2020. Especially after the Vietnamese government issued feed-in tariffs for grid-connected solar photovoltaic systems, the installed capacity of solar photovoltaic applications exploded in 2019. From studies carried out in the relevant literature, it can be said that support policies are highly important for the initial development of the renewable energy industry in most countries. This is especially true in emerging countries such as Vietnam. This paper reviews the feed-in tariffs issued and deployed in different regions of Vietnam for grid-connected solar photovoltaic applications. Moreover, the paper takes …
Labour market response to globalisation: spain, 1880-1913
2010
Abstract This paper analyses the impact of globalisation (trade and migration) on the Spanish labour market between 1880 and 1913 by examining the influence that globalisation factors had on agricultural and industrial wages. Our results show that the nineteenth century grain invasion had a negative impact on agricultural wages, whereas the fall in wheat prices did not benefit industry workers. We also found that migration pushed up real agricultural and industrial wages. As agriculture was the main sector in the economy, the final impact was a wage decrease. The negative impact of trade on agricultural and industrial labour markets partly explains the trade policy response of “integral pro…
Feed-in Tariffs for Grid-connected PV Systems: The Situation in the European Community
2007
Distributed generation demonstrates to be able to significantly influence the electric power system bringing considerable benefits to the quality of service and improving the energetic efficiency of the distribution network. In particular, in the last few years, distributed generation from renewable sources is considerably increased thanks to the many support policies promoted worldwide with the aim of facing the environmental issue and the problem of the permanent rise of prices of the fossil energy. In this contest the paper presents a study of the "feed-in tariffs" financing measure carried out, at present, in many European countries and responsible of the increase in these last years of…
