Abstract Italy will phase out electricity retail price regulation by July 1st, 2020. Until then, residential customers and small businesses who do not choose their supplier are served under a regulated tariff named “maggior tutela” (greater protection), supplied by the local distributor at a price set by the regulator. We review the literature on electricity retail competition – with particular regard to its expected effects on prices, innovation, and customer engagement – and the conditions under which competition is expected to deliver benefits. We perform a Structure-Conduct-Performance analysis of Italy's retail electricity market for residential customers, finding two issues potentially problematic: excessive market concentration and low customer engagement. We propose a phase-out mechanism that relies on graduality, asymmetric regulation, and a mandatory, opt-out collective switching exercise. The mechanism aims to rapidly reduce market concentration by leveraging behavioral incentives to customers to switch to the cheapest supplier.

I analyze energy-efficiency policy as a prescription of a minimum-efficiency standard for energy-using household goods like cars, building insulation, and home appliances. Such a policy has two effects. At the intensive margin, a household that invests will choose a more efficient device. At the extensive margin, there will be more households that choose not to invest at all. Thus, additional to and different from rebound effects, energy-efficiency policy may have unintended consequences. I analyze the equilibrium effects of a minimum-efficiency standard, taking price adjustments and household heterogeneity into account. A moderate minimum-efficiency standard increases demand for efficiency-enhancing household capital goods, and reduces energy demand. More stringent policy is shown to be less effective or even counterproductive. For the case of a fixed supply of efficiency-enhancing capital, it is shown that minimum-efficiency standards increase equilibrium energy demand. Finally, I analyze which households benefit from minimum-efficiency standards and which ones lose. A standard induces investing households to expend more for household capital and less for energy. The wedge between the induced expenditures and the private optimum is analyzed as a deadweight loss.

The Kyoto Clean Development Mechanism (CDM) is the first “global” and largest carbon offset instrument, supplementing national or regional cap and trade systems such as the European Union’s Emission Trading Scheme (EU ETS). This paper draws on weekly IDEACarbon survey data from 2008 to 2010 to empirically examine how investor’s perception of the CDM regulatory and administrative framework affects the price of CERs in secondary markets (denoted as sCER) and the price spread with EUAs. Results from cointegration analysis and GARCH modeling indicate that the perception of investors about the relative stringency and efficiency of this framework is a significant determinant of the sCER price and the EUA-sCER price spread. An increase in perceived stringency causes significant increases in sCER prices and a substantial narrowing of the EUA/sCER price spread (and vise versa). The analysis also shows that the EU ETS market was instable over the period examined, with a structural shift occurring at the end of 2008 likely due to the 2008 financial crisis.

AbstractWe analyze whether lower rents for energy-inefficient apartments reflect tenants’ willingness to pay due to a higher green awareness, purchasing power, or energy consumption costs. Based on a German rental apartment dataset from Q1 2007 to Q1 2019, we use interaction terms for socioeconomic characteristics in a hedonic regression model. We find that rents are lower for apartments with higher energy consumption, even in neighborhoods with lower levels of green awareness. This relationship is stronger in neighborhoods with higher purchasing power, such that communities with low levels of green awareness and high purchasing power show the steepest negative slope for increasing energy consumption (−8.6% from the highest to lowest rating). Thus, the rent-decreasing effect of purchasing power is higher than that of green awareness. Splitting the entire period into smaller windows, we find that the interaction effect of green awareness has emerged in the most recent years (2017–2019). This may be driven by changes in regulation, which have made it easier for tenants to assess the energy consumption before they rent, or by a general increase in green awareness over this period.

I argue that state-ownership and state-management of oil on behalf of the Iraqi people is not conducive to democracy and inconsistent with the principles of free market. I also argue that it can adversely affect economic development and might further impoverish the average Iraqi citizen. To resolve the problems, this note proposes a change to the “political” rules; i.e., change the Iraqi constitution, and provides an economic strategy to transfer oil wealth to the Iraqi people.

The countries comprising the Southern African Customs Union (SACU) are currently not very integrated into global value chains (GVCs), potentially missing out on important development opportunities. Accordingly, we explore high level options for promoting their integration. Given East Asia’s spectacular success with integrating into GVCs, we first assess the probability that SACU can copy their flying geese pattern. That was initiated by Japanese multinational corporations (MNCs) investing in successive East Asian countries thereby becoming the lead geese, to be joined subsequently by MNCs from other countries. We argue that the conditions for pursuing a flying geese approach are difficult to replicate in SACU. Therefore, we proffer and explore the proposition that South Africa could serve as the gateway for harnessing MNC geese flying from third countries into the SACU region, in time propelling regional development through knowledge and investment spillovers, and serving as a conduit into GVCs. However, there may be substantial obstacles to deepening this integration potential. Other African gateways are emerging as alternatives to South Africa. And some SACU governments would prefer to build regional value chains (RVCs) rather than prioritize GVC integration. We argue that RVCs are complements to GVCs. SACU countries, excluding South Africa, may not attract many world leading MNCs since their markets are small, but could attract smaller regional players from South Africa or elsewhere. Thus building RVCs in the short run could assist with integration into GVCs in the longer run. Overall, this requires harnessing South African and MNC geese to the South African gateway, in a mutually complementary strategy.

Despite the high CO2 emission intensity of fossil and especially coal fired energy production, these energy carriers will play an important role during the coming decades. The case study identifies the main technological trajectories concerning more efficient fossil fuel combustion and explores the potentials for lead markets for these technologies in China, Germany, Japan and the USA taking into account the different regulation schemes in these countries. We concentrate on technologies that have already left the demonstration phase. This is the case for supercritical (SC) and ultra-supercritical (USC) pulverized coal technologies that are already established. The analysis shows that the typical pattern of a stable lead market only applies to a limited extent. In the 1960s and 1970s, the USA has established a lead market for SC und USC technologies. In the meanwhile, Japan has surpassed the United States, although it started as a typical lag market. Japan has caught up in terms of supply factors, China in terms of price, demand and regulation advantage. This supports the hypothesis that - apart from the demand-oriented lead market model - push factors such as R&D activity play a strong role as well. The advantage of Japan mainly stems from its intensive R&D activities. It can also be observed that some other advantages – such as price and demand advantage – are shifting to China. China is practicing a leapfrogging strategy, and has already become a leader in the market segment of low and middle quality boilers, whereas Japan and Germany still dominate the world turbine market. The conclusion is that lead markets may switch over time to markets with high growth rates, although first mover advantages exist for some market segments such as turbines. First movers have a strong technological expertise which is important in the catching up process of late followers, and they may even profit from the growth in lag countries by exporting and cooperation activities. Thus international technology cooperation is a beneficial process for all involved parties.
