Hans-Werner Sinn (born 7 March 1948) is a German economist and was President of the Ifo Institute for Economic Research from 1999-2016. He serve on the German economy ministry’s advisory council. He is Professor of Economics and Public Finance at the University of Munich. [1]

Education and career

After studying economics at the University of Münster from 1967 to 1972 and receiving his doctorate from the University of Mannheim in 1978, Sinn was awarded the venia legendi in 1983, also from the University of Mannheim.

Since 1984 Sinn has been full professor in the faculty of economics at the University of Munich (LMU), first holding the chair for economics and insurance, and from 1994 the chair for economics and public finance. During leaves of absence from Mannheim and Munich he held visiting professorships (1978/79 and 1984/85) at the University of Western Ontario in Canada. During sabbaticals he was also visiting researcher at the London School of Economics, as well as at Bergen, Stanford, Princeton and Jerusalem Universities. Since 1988 he has been honorary professor of the University of Vienna, where he has given many lectures. In 2008 he was knighted with the Bavarian Maximilian Order for Science and Art, and in 2013 he was awarded the Ludwig Erhard Prize by the Ludwig-Erhard Foundation. Since February 1, 1999, Sinn has been president of the Ifo Institute for Economic Research. The Leibniz Association, the umbrella organization for Germany's federally funded research institutions, extolled his turnaround of Ifo after having taken over the presidency at a highly critical juncture in the institute’s history, bringing it back to a level of “very good, in some cases even excellent, research output” and turning it into "one of Europe's leading economic research institutes".[2] In 2006 he became president of the International Institute of Public Finance, a position he held until 2009. From 1997 to 2000 Sinn headed the Verein für Socialpolitik, the association of German-speaking economists. In 2013 he was awarded a further honorary doctorate, this time by the HHL Leipzig Graduate School of Management.

Sinn is fellow of the National Bureau of Economic Research in Cambridge, Massachusetts, and was the first German-speaking economist to deliver the Yrjö Jahnsson Lectures[3] in Helsinki (1999) and the Tinbergen Lectures in Amsterdam (2004).[4]

In the 2006 Handelsblatt ranking of German economists (Ökonomen-Ranking VWL), based on cross citations of SSCI papers in SSCI journals, Sinn ranked fourth.[5] In a study by Ursprung and Zimmer,[6] based on SSCI citations per author of the full oeuvre, Sinn ranked second of all German economists, after Nobel laureate Reinhard Selten. In the RePEc database he is the German economist most frequently quoted in academic works.[7] In a survey conducted by the Financial Times Deutschland among more than 550 German economic experts, Sinn was one of the two professors in Germany (the other was Herbert Giersch) to attract a large following of academic pupils, and in terms of political influence he ranked only behind Bert Rürup at the top of the list of German professors.[8] The British newspaper The Independent nominated him as one of the “ten people who changed the world” in 2011.[9] In its latest evaluation of the Ifo Institute, the Leibniz Association praised Sinn as one of “Germany’s most renowned economists, who constantly succeeds in bringing the most variedeconomic issues to public debate”.[10]

Sinn has published 85 scholarly articles in refereed journals, has written numerous newspaper articles and given many interviews. In addition he has made longer contributions for radio and television and has made many talk-show appearances. More than twenty articles on his person have been published in German and foreign newspapers.[11] His 2003 book "Ist Deutschland noch zu retten?" has stimulated policy discussion in Germany and influenced the Agenda 2010 reforms. With more than 100,000 copies in print, the book is one of the most popular public policy monograph in recent history. It has also been published in English as "Can Germany be Saved?" by MIT Press in 2007. As a reaction to the criticism of his book in the media, Sinn wrote a follow-up book in 2005, "Die Basarökonomie". His book the Green Paradox and his prior research on this topic triggered a worldwide debate, as did Sinn's research on Target balances, which is summarised in his book Die Target Falle. Sinn's book Casino Capitalism was named as one of the 50 best economics books of all time by Handelsblatt. His book "The Euro Trap: On Bursting Bubbles, Budgets, and Beliefs", published by Oxford University Press in 2014, reviews the effects of the adoption of the euro as a common currency and, in particular, the policy measures undertaken to combat the euro crisis. The book was hailed as "perhaps the most important scholarly book on the euro in at least a decade" by Kenneth Rogoff.[12]

Since 1989 Sinn has served on the Advisory Council of the German Ministry of Economics, and represented the Free State of Bavaria on the Board of Supervisors of HypoVereinsbank for ten years.[13]

Sinn lives with his wife near Munich. They have three adult children.

Research

With the exception of his diploma dissertation, also published in a journal, on the Marxian Law of the tendential decline of the rate of profit,[14] Sinn dealt in his early years particularly with economic risk theory. He made a name for himself with his dissertation "Ökonomische Entscheidungen bei Ungewissheit" (1980), published in English as "Economic Decisions under Uncertainty" (1983), with numerous spin-off articles. Subsequent work focused on the axiomatic basis of mean-variance analysis, on the foundation of the principle of insufficient reason, on the psychological foundation of risk preference functions and on the analysis of risk decisions under limited liability, which he subsequently developed into a theory of bank regulation in his Yrjö Jahnsson Lectures, "The New Systems Competition". In 2003, in the journal Finanzarchiv, he touched off an academic debate on banking regulation in which he was criticised by liberal economists for his favouring of stronger banking regulation to prevent excessive risk-taking. With his dissertation in 1977 on excess risk propensity under liability restrictions, Sinn, in the opinion of Martin Hellwig, preceded the pioneering analysis of Stiglitz and Weiss of 1981.[15] [16] His work in this area was again published as a reprint volume in 2008. On the basis of his research on risk theory, Sinn developed his influential theory of the insurer state, in which he interpreted the redistributing activity of the state via the tax-transfer system as insurance protection, showing that this activity can have a favourable influence on people's willingness to take risks. His work on the Theory of the Welfare State in 1995 is considered an important contribution on the legitimacy of state redistribution activity.[17]

Sinn has published numerous studies on the theory of economic cycles, environmental economics, foreign trade issues, including ones on the so-called asset approach and on the micro foundations of a model of temporary general equilibrium.

Problems of longer-term economic growth were also on his research agenda. Sinn was the first economist to formulate the central-planning model of economic growth in the tradition of Robert Solow as a general equilibrium model with decentrally optimizing agents and market clearing conditions in an article published in German in 1980 and two years later in English, and before similar work by Chamley in 1981 and Abel and Blanchard in 1983.[18][19][20][21]

His study on the stimulating effects of accelerated depreciation and the various components of capital income taxation on intertemporal, international, and intersectoral allocation is still considered one of the standard works in this field.[22]

Sinn contributed to the discussion on German pension reform with his article "Pension Reform and Demographic Crisis. Why a Funded System is Needed and Why it is Not Needed" published in 2000.[23] Here, with the help of present-value equivalents, he showed that the low returns from statutory pension insurance based on the pay-as-you-go method has only an apparent efficiency disadvantage in comparison to a capitally funded procedure. This finding was further developed in a number of subsequent studies.

Recently Sinn has turned to the problem of the global warming in an article "Public Policies against Global Warming" and in his book "Das grüne Paradoxon" (the English version, The Green Paradox, was published by MIT Press in 2012). In these studies Sinn developed a supply-side theory of climate change by linking climate-theory approaches with the theory of exhaustible natural resources. His "green paradox" states that environmental policies that promote substitute technologies over time with increasing intensity (and in the process lower the prices for fossil fuels relative to the values they otherwise would have obtained) will induce the resource suppliers to accelerate extraction, thus contributing to global warming.

Economic policy positions

In 2005 he was one of the first German economists to sign the "Hamburger Appell", which argued for fundamental market-economy reforms and rejected demand-oriented concepts of economic policy. At the same time Sinn employs the instruments of Keynesian demand theory for his analyses of economic activity. With his studies on pension insurance, in which he argued for partial capital funding, as well as by providing direct advice to the Federal Ministry of Labour and Social Affairs (Germany) (through CES, his university institute) and by contributing to an expertise on pensions for the Ministry of Economics, Sinn had a hand in the introduction of the "Riester-Rente", a privately financed pension scheme support by the German government in the form of grants and tax deductions.

In 2003 he saw Germany's attractiveness as an investment location endangered by too high labour costs and called for structural reforms of the labour market. These include escape clauses for collective wage agreements, the abolition of dismissal protection laws and longer working hours without wage compensation. He has also criticised the employment-restricting effects of the German wage replacement system. As an alternative he developed in 2002 the model of activating social welfare. His policy recommendations influenced the Agenda 2010 reforms. According to Prof. Wolfgang Wiegard, then member of the Council of Economic Advisors, his work was the blueprint for the Agenda 2010 reforms.[24]

Sinn has called the German economy a "bazaar economy" because the share of input from abroad in German industrial production is on the increase. At the same time he points out that this is not to be equated with a breaking off of value added in exports. Instead Germany has decimated its domestic sector via excessive wage increases and has driven excess amounts of capital and skilled labour into the labour and knowledge-intensive export sectors, where fewer less-skilled workers can be employed as have been set free in the domestic sectors. At the expense of the domestic sectors, Germany has inflated value added in exports too strongly and at the same time has placed too much emphasis on the final stages of production. As a result, a pathological export boom occurred.

The world economy crisis is traced back by Sinn to an abuse of liability limitation by American investment banks. The lack of capital reserve requirements gave these banks the possibility to pursue their business with inadequate capital reserves and encouraged them to gamble. In addition the lack of personal liability for homeowners created in a similar way an exaggerated willingness to take risks and thus caused the United States housing bubble. To correct this situation Sinn has called for considerably higher capital reserve requirements, the balancing of offshore business and a return to the accounting principle of the lower of cost of the German Commercial Code (HGB).[25]

Against the background of the Great Recession, Sinn advocates a return to the tradition of ordoliberalism and of ordoliberal economists like Walter Eucken, Alfred Müller-Armack, Alexander Rüstow, and Ludwig Erhard, who argued a strong state should provide a framework or economic order inside which market forces and free market competition can develop.[26][27] Markets do not regulate themselves (Selbstregulierung), but are capable of self-controlled processes (Selbststeuerung) inside an institutional framework provided by the state.[28]

Sinn accuses the Greens of pursuing environmental protection policies with unsuitable means and of ignoring the economic laws of the European emissions trading system as well as the worldwide market for fossil fuel. In his book, The Green Paradox, he argues for including all countries of the world in a post-Kyoto, joint emissions trading system. He also favours employing a withholding tax on the yields of financial investments to curb the desire of the resource providers to extract more fossil fuels.

During the 10th Munich Economic Summit in May 2011, Sinn alleged that the ECB had been conducting what he termed a “stealth bailout” of Greece, Ireland, Portugal and Spain for the past three years, financing capital flight and/or current account deficits by allowing them to accumulate massive liabilities in their TARGET2 accounts.[29] He subsequently published his views in the press[30][31] and specialized websites,[32][33] followed by a working paper that analyzed the issue in detail.[34] He also discussed Germany's capital exports since the introduction of the euro and the prospects such exports could face if the euro crisis continues and leads to the introduction of Eurobonds, which he opposes.[35] While drawing much acclaim for his focusing on Target2 imbalances, the conclusions he draws have been fiercely opposed by other economists.[36][37]

Controversy

In July 2012, Sinn was one of the eventually more than 270 signatories of an open letter written by Walter Krämer of the Technical University of Dortmund against Chancellor Angela Merkel’s Brussels agreement on direct recapitalization for ailing European banks.[38] Economics professors Frank Heinemann of Berlin and Gerhard Illing of Munich drafted a public answer, arguing that a “banking union” in the sense of common supervision was, in fact, critical to saving the euro, but they also objected to bank recapitalisation using the taxpayers' money. This letter also attracted more than 200 signatories from the banking and the academic communities. The "momentous tiff", as The Economist dubbed it, has in the meantime become more nuanced, with Krämer and Sinn publishing a more muted version in which they endorsed a banking union based on the bail-in principle. Sinn joined Heinemann and Krämer in publishing a joint appeal on the issue in Plenum der Ökonomen, an internet forum of German professional economists.[39]

Public influence

According to a poll conducted jointly by the Financial Times Deutschland and the Verein für Socialpolitik (the German economics association) among 550 German economics experts in 2006, “only two representatives of our profession exert an appreciable influence on policymaking: Bert Rürup and Hans-Werner Sinn”.[40] A study in 2007 placed Sinn, in terms of number of citations in scientific journals, second to German Nobel laureate Reinhard Selten.[41] The British newspaper The Independent named Sinn among the ten most important people who changed the world in 2011.[42]

The German Business weekly WirtschaftsWoche ranked Sinn 62 among the 100 most powerful people in Germany, and placed him in the No. 1 position among the “Most Important Economists” in the country.[43] In 2012, he was included in the 50 Most Influential list of Bloomberg Markets Magazine. In 2013, the Frankfurter Allgemeine Zeitung placed Sinn first on their list of economist with most political influence.[44]
