On the African Continental Free Trade Area
2021
Africa-wide integration projects have competed with step-wise regional integration since independence. This chapter examines the new project of an African Continental Free Trade Area (AfCFTA). The project’s potential to become an economic game-changer for Africa is analysed alongside the likely pitfalls of the arrangement. We conclude that while a well-staged AfCFTA can resolve a number of critical issues associated with intra-African integration, it cannot replace existing RECs, especially not with respect to negotiating extra-regional trade agreements. It is argued that to avoid undercutting the entire process, the entrenched logic of exceptions and exclusions from tariff liberalization m…
Regional Integration in Trade Theory
2021
Given widespread scepticism in trade economics about the value of RECs comprised of developing countries, the formal theory of regional economic integration is critically examined in four stylized configurations. Based on the overarching logic of trade creation and diversion, the usual diagrammatic treatment of tariff effects is critically discussed in terms of its numerous shortcomings. A single-country and REC-wise diagrammatic treatment of tariffs in the presence of increasing returns is proposed to allow quantitative assessment of the arguably most promising case for South-South RECs. Building on the literature, the cases of full and incomplete specialization within a regional group are…
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, …
Electricity demand response schemes in China: Pilot study and future outlook
2021
Abstract Electricity demand response (DR) improves the overall energy management efficiency and allows for the integration of large-scale renewable energy into the power grid through interactive management and control of the supply and demand sides. However, in China and other emerging countries (e.g., Japan and Australia) with DR programs, the DR market mechanism is not well-established. This is particularly the situation in countries where the state power system is not freely open to participate in the DR market. Previous research has proven that considerable DR resources are largely existing in the demand side; however, the dearth of a market mechanism hinders the development of DR. Henc…
Energy saving in airports by trigeneration. Part II: Short and long term planning for the Malpensa 2000 CHCP plant
2006
With reference to the feasibility analysis for CHCP applications in airports performed in Part I of this work, the optimal strategy for repowering and operation of the Malpensa 2000 CHCP plant is here discussed. The analysis starts from experimental energy demand data, available on hourly basis for an entire operational year. After a description of the CHCP lay-out, the optimal management strategy was determined keeping into account the articulated energy tariff system and the technical characteristics of components. A profit-oriented optimization of the repowering actions to take up to 2010 is presented, based on the expected growth of energy consumption due to the scheduled increases in t…
Six-years-long effects of the Italian policies for photovoltaics on the grid parity of grid-connected photovoltaic systems installed in urban contexts
2017
Abstract The purpose of this study is investigating the grid parity (GP) time and the levelized cost of energy (LCOE) of grid-connected photovoltaic (PV) systems installed in densely urbanized contexts. The analysis, which was elaborated for three Italian cities, considered the effects of the promoting policies enacted by the Italian government from June 2010 to May 2016. An appropriate methodology was applied with the aim of realistically defining the energy produced by PV systems installed on buildings with different roof types and number of floors. The calculus of the disbursements considered the operating, maintenance and insurance costs and the wear of PV panels and inverters. The resu…
Economic analysis on dynamic photovoltaic systems in new Italian “feed in tariffs” context
2013
Dynamic photovoltaic generators, based on the application of solar-trackers, are able to give an increment to the electric energy production from solar source. Their realization and maintenance costs are certainly higher than those of fixed ones. In this paper the Authors propose a method to estimate the increment of electrical energy generation that must be guaranteed by a dynamic photovoltaic generator, so as its realization could be more favorable with respect to that of a fixed generator one with the same rated power. This method, developed by means of classical economic indexes like the Pay-Back-Period and the Net Present Value, takes in to account the economic incentives for the PV sy…
Experiencing Urban Mining in an Italian Municipality towards a Circular Economy vision
2017
Abstract Selective waste collection in Italy has undergone significant changes over the last decade, highlighting very different approaches from one region to another. Research results presented in this paper are underlying differences between geographical regions and use them as a model of good practices to improve the less optimized systems. In the last decade, the Trento City Council has established a goal – the optimization of selective municipal solid waste collection – that led to a very low amount of recyclable materials in the residual fraction. More than that, for the first time sanitary textiles have been considered as a separable fraction at the source; for a long time this type …
A comprehensive tool for efficient design and operation of polygeneration-based energy μgrids serving a cluster of buildings. Part II: Analysis of th…
2013
Abstract The potential of polygeneration systems, in terms of profitability, energy saving and pollutant emissions reduction, highly depends on several factors such as plant efficiency, local normative and tariff conditions and reference technologies adopted to compare the results. In Part I of this paper a reliable tool was described, capable of optimizing the lay-out, design and operation of an integrated polygeneration system serving a cluster of buildings with their heat, cooling and power demand; the tool represents an excellent instrument to perform sensitivity analyses, thus enabling the analyst to formulate general design criteria and predict the effects of any change in the boundar…
The Energy System of Sicilian Region, Italy: 2014 situation and evolutionary trends
2015
The development of reliable energy scenarios are become increasingly more important and crucial due to scientific interest but also because it is essential for the deployment of effective energy policies in the territory. The depletion of Fossil Fuels and the need for the most industrialized countries to achieve the target of a sustainable development have induced important national, European and global initiatives. These actions have led to major changes on each energy system of countries and regions, contributing to the evolution of new local energy systems. In this paper, the Authors have collected, processed and analyzed the data concerning the evolution and changes of the Sicilian ener…
