| Summary/Abstract |
The new potential of Distributed Energy Resources (DER), residential consumers, buildings, and prosumers in terms of controllable devices, self-generation, and storage makes them more active in the market encouraged by lower electricity prices. In addition, integrating a higher volume of volatile Renewable Energy Sources (RES) that unstress the public grid by local trading interactions is a desirable target of Local Electricity Markets (LEM). In this paper, we propose a blockchain trading mechanism to simulate the electricity transactions for 11 modern smart houses with more than 300 appliances, 8 roof- or faced-PV systems, and smart-metered 15-min readings that form a small-size community. The electricity generated at the community level lowers the electricity bills and brings benefits for prosumers (sellers) and consumers (buyers). Several trading mechanisms for LEM transactions including auctions such as Uniform Price (UP), Pay-As-Bid (PAB), Generalized Second-Price (GSP), Vickrey-Clark-Groves (VCG) methods are implemented to evaluate the benefits and show their efficiency. After the market is initially cleared, an adjustment coefficient of the price is proposed for both sides (seller and buyer) to enlarge the trading potential at the community level using blockchain technology. It proves to bring excellent results to the LEM participants and enhance trading with outstanding benefits.

| Summary/Abstract |
China has a built-in inflationary tendency because of the partially-reformed nature of its economic system. Specifically, the post-1978 marketization of the economy has interacted with the continued state ownership to create an inflationary 'liquidity tango' between the state-owned enterprises (SOEs) and the state-owned banks. Whenever the hard budget constraint is imposed on the SOEs, China's dysfunctional financial system would impart a deflationary bias to the economy and render China a capital exporting country by constraining the growth of aggregate demand to be less than the growth of aggregate supply. The use of price mechanisms as the only instruments for all economic problems is not appropriate for China's transitional economy, e.g. trade surpluses are better handled by the establishment of an efficient financial intermediation mechanism than by appreciation of the Yuan.
