Hans-Werner Sinn

from Wikipedia, the free encyclopedia
Hans-Werner Sinn (2012)

Hans-Werner Sinn (born March 7, 1948 in Brake near Bielefeld ) is a German economist . He is emeritus professors at the Ludwig Maximilian University of Munich and was 1999-2016 President of the Ifo Institute for Economic Research . In his scientific work he devotes himself to a. The theory of decisions in the event of uncertainty , the theory of intertemporal general equilibrium, German reunification , system competition, the euro , climate change and economic policy decisions in a large number of contributions.


Sinn was born in 1948 into a working class family close to the SPD ; his father was a taxi driver and member of the SPD. A grandfather of Sinn was persecuted as a social democrat by the National Socialists and died in a concentration camp . As a child, Sinn was a member of the Falken , and for a few years until around 1970 a member of the SPD. Sinn attended the Helmholtz high school in Bielefeld, where he graduated from high school in 1967 .

After studying economics at the Westphalian Wilhelms University of Münster from 1967 to 1972, Sinn moved to the University of Mannheim , where he received his doctorate in 1978 and his habilitation in 1983 .

From July 1984 to February 1994, Sinn held the chair for economics, especially insurance science, at the Ludwig Maximilians University in Munich . He then switched to the Chair of Economics and Public Finance , where he taught the finance curriculum until his retirement in 2016 .

He was a professor at the University of Western Ontario in Canada for two years , as a visiting professor at the London School of Economics and at the Universities of Bergen , Stanford , Princeton and Jerusalem . He was the only German so far to hold Yrjö Jahnsson Lectures in Helsinki and Tinbergen Lectures in Amsterdam . Since 1988, Sinn has also been an honorary professor at the University of Vienna .

From 1997 to 2000 he was chairman of the Verein für Socialpolitik , the professional association of German-speaking economists, which he fundamentally reformed. Sinn was particularly committed to the internationalization of economics in German-speaking countries. During his tenure, he founded two journals - the German Economic Review and Perspektiven der Wirtschaftsppolitik -, created the Gossen Prize for young economists who publish internationally, and set up an extensive bonus program for lectures by young German-speaking scientists at international specialist conferences. Between 2006 and 2009, Sinn was President of the International Institute of Public Finance , the world association of public finance. He has also been a Fellow of the National Bureau of Economic Research in Cambridge (USA) since 1998 .

In 1991, Sinn founded the Center for Economic Studies at the Ludwig Maximilians University, whose main task was to bring international guest researchers to the economics faculty. On the basis of the CES, he founded the first graduate program for economists in Germany that is mandatory for all doctoral students in the faculty. In 1999, together with the Ifo Institute for Economic Research , whose presidency he took over in the same year, he created the international CESifo research network within the framework of CESifo GmbH.

From February 1999, Sinn was President of the Ifo Institute for Economic Research. During his tenure, the institute was given a decentralized structure with eight divisional heads who, with a reduced number of professors, are also assigned to the economics faculty of the LMU. Under his leadership, the institute was converted back in January 2010 from a service facility (facility that primarily performs scientific infrastructure tasks) to a research facility whose research performance was rated as "very good," in the regular evaluation of the Ifo Institute initiated in 2012 by the Senate of the Leibniz Association . in parts even excellent ”. The Leibniz Association emphasized that Hans-Werner Sinn had repeatedly managed to initiate important public debates on a wide variety of topics. Hans-Werner Sinn's term of office as Ifo President ended in March 2016 when he turned 68 and retired . Since 2017 he has been a "permanent visiting professor" at the University of Lucerne .

Hans-Werner Sinn was a member of the Supervisory Board of HypoVereinsbank from 2000 to 2010 . In 2016 he was a participant in the Bilderberg Conference in Dresden .

He lives with his wife in Gauting near Munich , they have three grown children.

Research areas

In his first academic years, Sinn mainly dealt with economic risk theory . The focus of this work was on the symbiosis of expected utility theory and the axiomatic foundation of the mean-variance analysis , especially the foundation of the principle of insufficient reason, the psychological foundation of risk preference functions and above all the analysis of risk decisions with liability restrictions. According to Martin Hellwig's judgment , Sinn anticipated the work by Stiglitz and Weiss from 1981, which had previously been considered the basic work .

This was followed by a large number of papers on business cycle theory , environmental economic and foreign trade- related topics, including papers on the so-called asset approach and on the micro-foundation of the general model of the temporary equilibrium.

Problems of longer-term economic growth were a particular focus . Before Abel, Blanchard and Chamley, Sinn formulated the economic central planning model of economic growth in the tradition of Robert Solow as an intertemporal general equilibrium model with decentralized optimizing actors and market clearing conditions.

In 1987, Sinn's habilitation thesis on the incentive effects of accelerated depreciation and the various components of capital income taxation on intertemporal, international and intersectoral resource allocation was published .

In 1991, Hans-Werner Sinn and his wife Gerlinde Sinn published the book Kaltstart , which offers an analysis of the errors in the unification policy. The authors criticize the "squandering policy" of the Treuhandanstalt at the expense of the East German population and the policy of rapid wage equalization, which anticipates market developments and was carried out under the influence of western employers' associations and trade unions, which was planned as an investment brake to prevent foreign investments for their own protection. The book has been translated into several languages.

Sinn sees the fundamental justification of the welfare state in its function as an insurance institution. State redistribution insures citizens from dangers to life that are not covered by private insurance, and by doing so it increases people's willingness to take risks, which has productive economic effects.

Sinn's 2003 book Can Germany still be saved? triggered a debate on the reform backlog in Germany and, in the opinion of the then Chairman of the Advisory Council, can be seen as a source of ideas for Agenda 2010 . At the center of the book is the proposal to set up so-called activating social assistance. This makes use of personal wage subsidies for the low-skilled in order to ensure that nobody has to live on what they can work for themselves anymore and that the sum of these subsidies and the market-clearing wage results in a socially acceptable total income above the socio-cultural subsistence level . With over 100,000 printed copies, the book is one of the most successful economic monographs of today. The English translation was recognized by an overview article in the Journal of Economic Literature , as it "made an important contribution to the question of how the welfare state should be reformed in order to harness the benefits of globalization and to help the poor."

In The Casino Capitalism (2009), Sinn describes how the global financial crisis came about in 2007 as a result of political and market failures . He raises the accusation that banks were allowed to work with insufficient equity capital due to inadequate regulation and were therefore inclined to "gamble". The Handelsblatt called this book one of the 50 most important economics books of all time.

Political positions

Sinn himself describes his economic and political position as “financial science”, that is, as a school of thought that emphasizes the active role of the state in overcoming distribution and allocation problems in the market economy. However, he also expressed himself positively about the ordoliberalism in the sense of Erhard and Eucken , according to which the state must above all define the regulatory framework of the market economy.

Shortly before the 2005 federal election , Sinn and 242 other German economists signed a public appeal, the Hamburg Appeal , for economic policy reforms in Germany.

Euro crisis

Sinn was one of the first of 279 economics professors who, during the euro crisis, signed an appeal initiated by Walter Krämer together with Stefan Hoderlein (economist) (Boston) and Manfred Deistler (Vienna) in July 2012, which opposed the “mutualisation of bank debts” applies a common deposit insurance within the euro zone. In a press release, the Ifo Institute made it clear that, unlike some press releases, Sinn was not one of the authors of the appeal.

Sinn sees the cause of the European debt crisis in an artificial interest rate convergence induced by the euro, which in the first years of the euro led to an inflationary credit bubble in the countries of southern Europe . This reduced the international competitiveness of the affected countries and led to high current account deficits for the debtor countries against the historical hard currency countries.

When the interbank market dried up in the wake of the global financial crisis from 2007 and the European financial and debt crisis in particular , the European credit institutions, especially in the peripheral countries, began to refinance themselves increasingly from their national central banks, which the ECB through a Loosening of their pledge policy as well as the tolerance of ELA credits made possible. The additional liquidity thus created at national level was used to continue to finance the current account deficits, to repay debts abroad and to buy property there. The corresponding net transfers to other countries, the so-called balance of payments deficits, are measured by the Target balances (see also Target2 ).

According to Sinn, the Target balances are public international loans because they are payments that the national central banks credit each other due to a lack of deposits with the Eurosystem. They are comparable to the other official financial aid such as the rescue packages, but they are made possible by the Governing Council instead of the parliaments of the euro zone . The Target demands of the Northern European Euroblock reached their peak in August 2012 with over 1,000 billion euros. At that time, there was only transfer money in Germany that had arisen through credit creation by other central banks. Thanks to Sinn, the Target balances found their way into the public debate. He was also the first to show the relationship between Target balances and balance of payments imbalances .

He also demands that the purchases of government bonds by the ECB should end. He was one of 136 German economics professors, including Roland Vaubel , Bernd Lucke , Jürgen B. Donges , Manfred JM Neumann and Georg Milbradt who, shortly before the federal elections in September 2013, accused the ECB of illegal monetary state financing in a call . He accuses the federal government and the German Bundestag of having failed to negotiate clear credit terms for the crisis procedure. In his opinion, the European stability mechanism leads to the weakening of the euro and to the endangerment of the European work of unification.


In the Frankfurter Allgemeine Zeitung, Sinn took the view that migrants cost the German state more net than they brought it. The article had two parts. The first addressed the labor market, for which immigration is an asset. The second part deals with the state, and there is a fiscal loss to be accounted for. Herbert Brücker had already criticized this view a year earlier. Sinn refers to the bills from Holger Bonin, who comes up with a long-term loss of 79,000 euros per refugee. Also Bernd Raffelhüschen comes to substantial net cost of the refugees for the German government.

Energy policy

In manager magazin , Sinn described the energy turnaround in Germany away from nuclear power as an ecological wrong track and formulated “The only hope of humanity was nuclear power”. Sinn regularly gives critical lectures on the German energy transition at various events. In his book The Green Paradox he developed a supply-side climate theory, which basically states that measures to limit the demand for fossil fuels are irrelevant to the climate if it is not possible to restrict resource extraction. The book has also been translated into English and has sparked an extensive international discussion. Sinn does question the German path to the energy transition, but affirms the necessity of an energy transition itself. To this end, he recommends global emissions trading and the global transition to a system of withholding taxes on capital gains in order to deprive resource owners of the incentive to turn their natural resources into financial assets.

In his article Buffering Volatility , Sinn came to the conclusion that, despite the reduction in storage requirements through a complete power network from the Alps to Norway, it would not be possible to achieve a market share of more than 50% for wind and solar power if the buffering was used by using pumped storage power plants and foregoing any curtailment of the power peaks that exceed consumption. Scientists at the DIW criticized Sinn's statements in the same specialist journal and attested, among other things, to having made implicit assumptions in his methodology that would have significant effects on the results. Therefore, his results differed from other studies on the subject. In doing so, the scientists replicated Sinn's methodology, but without adopting certain premises from Sinn, which, according to the authors, significantly changed the results. So lead z. B. Sinn's premise, contrary to the established state of research, to forego curtailments entirely, to a significantly excessive storage requirement, since under this assumption every single kWh of wind and solar power would have to be stored. Among other things, this means that his results regarding the necessary expansion of electricity storage systems are often one or two orders of magnitude higher than the results of other studies. In fact, it is more economical to regulate part of renewable generation peaks than to store them entirely. This makes it possible to manage with much less storage volume. In their conclusion, the authors come to the conclusion that “the need for electrical energy storage does not limit the further expansion of variable renewable energies”. Results that deviate from a large number of other studies would come about because he only considered “corner solutions”; H. either no storage at all, which would lead to massive curtailments, or no curtailments at all, which in turn would lead to a very high storage requirement. However, the combination of different options is cost-efficient. In addition, the authors emphasize that the need for electricity storage can be further reduced by using further flexibility options such as coupling the electricity sector with the heating and transport sector or the generation of hydrogen.

Climate policy

In 2008, in his book The Green Paradox , Sinn criticized the fact that politics and theory dealt almost exclusively with the demand side of the carbon market and neglected the supply . In fact, it would be of no use if a group of countries reduced the demand for fossil fuels, since the suppliers would then sell their quantities elsewhere in the world at lower prices. Whatever comes out of the ground is burned - if not in Europe, then elsewhere. Despite considerable efforts to reduce demand in Europe, up to this point in time (2007) there had been no reduction in the global quantities of CO 2 emitted . On the contrary, CO 2 emissions are increasing unabated.

According to Sinn, the “green paradox” consists in the fact that the owners of the resources interpret the announcement of the energy turnaround as the threat of market destruction and therefore react to it by accelerating the extraction of resources. This carries the risk that climate change will even accelerate. Countries that do not participate in the demand restrictions therefore have a double advantage. You can not only burn the carbon released by the “green” countries (“leakage effect”), but also the amount of carbon that the suppliers take out of the earth prematurely in accordance with the “green paradox”.


In the 2019 article, Coal Engines, Wind Engines, and Diesel Engines: What Does the Carbon Footprint Show? In the study that he wrote together with Christoph Buchal and Heinz-Dieter Karl, Sinn comes to the conclusion that, in the best case scenario , electric cars have a CO 2 balance that is comparable to diesel-powered cars. Specifically, the Tesla Model 3 Long Range Dual Motor was compared with a Mercedes-Benz C 220 d (OM 654) .

The conclusion of the study was then picked up in the media and by scientists and sometimes heavily criticized; Among other things, a study published in the Joule journal in 2019 took Sinn's work as a reference, specifically to illustrate the usual deficiencies in the premises and methodology of studies that attest electric cars only minor environmental benefits. According to public criticism, Sinn's study contained a number of misconceptions. So be u. a. worked with consumption data from the NEDC driving cycle instead of the much more realistic WLTP driving cycle. An author for Wirtschaftswoche even assumed that he was deliberately biased in favor of the diesel engine: “The suspicion arises that a certain result should be achieved in favor of diesel. [...] The studies by the Paul Scherrer Institute, Fraunhofer, ICCT and Forschungsgesellschaft für Energiewirtschaft, Agora Energiewende [...] should be much closer to the truth. ”Sinn and Buchal responded to the criticism in a guest article in the FAZ .

Public influence

According to a survey conducted by the Financial Times Deutschland together with the Verein für Socialpolitik among 550 German economic experts in 2006, the respondents wrote that “only two representatives of their own guild had a significant influence on politics: Bert Rürup and Hans-Werner Sinn”. According to a study by the Center for European Economic Research and the University of Konstanz in 2007, Sinn ranked second among German economists after Reinhard Selten , measured by the number of citations in economic journals . In the list of “The Most Important Economists” published by Wirtschaftswoche 2011, he took first place. For the British newspaper The Independent , Sinn is one of the ten most influential people who changed the world in 2011 because of his research on Target balances . The research database RePEc regularly determines the most research-intensive economists worldwide on the basis of citations. In 2012 up to and including 2016, Sinn achieved the best place for a German economist, his ranking ranks him in the top 0.2% worldwide and below 0.1% across Europe. He was the only German on the Bloomberg list of the fifty most influential business figures worldwide in 2012. According to a survey by the magazine Cicero on the influence on public discourse in the past decade, which listed the 500 most important German intellectuals in January 2017, Sinn was in fourth place behind Martin Walser, Peter Sloterdijk and Peter Handke.

According to the economist ranking of the Frankfurter Allgemeine Zeitung , based firstly on a survey of members of the Bundestag and employees of federal ministries with the question "Which economists do you most appreciate the advice or publications for your work?", Secondly the media presence and thirdly the evaluation of the publications in In the form of scientific articles from the last five years, Sinn took first place in Germany in 2013, 2014 and 2015. After his retirement, he slipped to second place. Although Sinn does not appear in the top 50 in the research category, which is based solely on the scientific articles of the last five years and does not take scientific monographs into account, the FAZ explains , no other economist in Germany has so much weight in the media and Politics and meaning are also present in research. Something similar happened in 2015.

In his comment on The Tabloid Professor in the Financial Times Deutschland on March 30, 2007, the business journalist Mark Schieritz said that the less attention paid to his theses, the bigger the journalistic artillery would make. 2012 marked Schieritz in the time sense as "economic seismograph of the Republic" who had come with his books and interviews the sound to the economic megatrends in the past 30 years.


In October 2008, in the public discussion of the financial crisis , Sinn described German managers as the scapegoats to be looked for in every crisis. In the world economic crisis of 1929 it hit the Jews in Germany , today it is the managers. This statement met with criticism not only from the Central Council of Jews in Germany , but also from politicians from various parties and representatives of public life, as the statement equated the criticism of the managers with the persecution of the Jews . On the same day, Sinn withdrew the comparison. Shortly afterwards, the Ifo published statements in which Jewish acquaintances and colleagues defended Sinn against its critics.

In the course of the European financial crisis, Finance Minister Wolfgang Schäuble criticized Sinn's position regarding the euro rescue package . According to Schäuble, "the authority of academic titles and scientific institutes that are subsidized with a lot of money from German taxpayers has a special responsibility". However, the calculations for Greece are "again an example of how this responsibility is not met very well". In a press release, the Ifo Institute rejected the criticism and accused Schäuble of not taking into account the importance of the Target balances in his calculations. In the commemorative publication, which received Sinn as part of his farewell, Schäuble praised Sinn's deeply European orientation and praised his sharp-tongued and intellectual sharpness, which is not always pleasant for politicians, but which one has to endure. He explained: "He may now leave office, unfortunately - but stop taking part in the political debate as an economist, he must not!"
