<\/p>\n
Lion has published 36 articles in peer-reviewed economics and engineering journals, including single-author papers in the leading field outlets Energy Economics<\/em>, The Energy Journal<\/em>, and Applied Energy<\/em>. Google Scholar lists a total of 7243 citations, yielding an h-index of 35. Two of his papers are the most cited in recent times in leading field journals, \u201cOptimal Share<\/a>\u201d in The Energy Journal<\/em> and \u201cMarket Value<\/a>\u201d in Energy Economics. <\/em>RePEc lists Lion among the top 5% energy economists<\/a>; FAZ lists him among the top 30 German research economists<\/a>. Lion\u2019s publications have won several awards, including the best paper award of the International Association for Energy Economics.<\/p>\n <\/p>\n [vc_row][vc_column width=”1\/2″][vc_column_text]<\/p>\n Financial contracts for differences: The problems with conventional CfDs in electricity markets and how forward contracts can help solve them<\/strong><\/a>.
