The German Institute for Economic Research (), or, more commonly DIWBerlin, is a economic research institute in Germany, involved in basic research and policy advice. It is a non-profit academic institution, financed with public grants from the Berlin Senate Department for Economics, Technology and Research and the Federal Department for Economics and Technology. DIW Berlin was founded in 1925 as the Institute for Business Cycle Research and was later renamed.

DIW Berlin presents its research results in science journals, within the scope of national and international scientific events as well as at workshops, symposia and colloquia. Current economic and structural data, forecasts and advice as well as services in the area of quantitative economics are provided to decision makers in economics and policy and the broad public. Furthermore, the research results often meet with a major response in the news media.

Leadership and organisation 
The legal status of DIW Berlin is that of a registered association. The association's bodies are the Members, the Board of Trustees, the Executive Board and the Scientific Advisory Board. To date, there are 185 employees, 102 of them being researchers.

Research departments 
The institute is divided into ten research departments, which are:
 
 The Department of Macroeconomics focuses on the empirical and theoretical analysis of aggregate economic developments as well  as national and international economic policy.
 The Department Forecasting and Economic Policy uses modern macroeconomic methods to analyze economic policy issues. Economic forecasting is a key component of the department's work.
 The Department of International Economics focuses on monetary and financial issues affecting the global economy. It concentrates on two key activities: examining international financial markets in terms of their economic functionality and analyzing the contribution of financial development to the goal of shared growth in developing and emerging countries.
 The Department of Energy, Transportation and Environment researches different strategies of sustainable development in energy, transportation and the environment in order to formulate sound policy recommendations.
 The Department Climate Policy uses empirical and theoretical methods to explore Germany and Europe's transition to sustainable energy—for example, by analyzing policies related to energy efficiency in buildings as well as the shift to sustainable, climate-friendly power production.
 The Department of Competition and Consumers aims to produce robust evidence of how society and markets function. Its research combines approaches from industrial economics with behavioral and experimental economics, thus enabling a comprehensive analysis of strategic interactions, market allocations, and human behavior.
 The Department of Firms and Markets analyzes firms’ strategic behavior and its impact on efficiency, productivity, and growth as well as the institutional and political environment in which firms operate.
 The Department of Public Economics analyzes how financial, fiscal, and social policies influence economic decisions made by individuals, households, and companies.
 The Department of Education and Family explores education and family-related issues primarily from a microeconomic perspective. One key question is the extent to which it is possible to fully develop the human potential of a country's economy.
 The Socio-Economic Panel Study (SOEP) is a research-based infrastructure facility at DIW Berlin funded by the German Federal Ministry of Education and Research (BMBF) and state governments. The SOEP is one of the world's largest and longest-running surveys of individuals and private households. Numerous studies based on SOEP data examine mechanisms behind the distribution of social resources.

Graduate Center 
Since 2006 the Graduate Center (GC) of DIW Berlin offers about 15 scholarships per year for PhD positions in economics in cooperation with Berlin's largest universities: Free University of Berlin, Humboldt University of Berlin, and Technical University of Berlin. The Graduate Center is located within the DIW building in the center of Berlin. The academic research of students focuses on applied topics. The four-year program is divided into two parts: while students receive academic training in economics and related social sciences during the first year, in years two to four on-the-job training in DIW research projects leads them to complete their doctoral theses. The application period is between January and March.

Co-operations 
A broad range of predominantly external Research Directors, Research Professors and Research Affiliates research along with the employees of DIW Berlin. They co-operate for a specific time, perform cross sectional tasks, care about scientific surveys (such as diploma thesis, dissertations) and release important pulses for the institute.

The DIW is also part of the Leibniz Association, (Leibniz-Gemeinschaft), a collection of non-university research institutes in Germany. Along with five other leading institutes, the DIW publishes a joint report on the state of the German economy, the Gemeinschaftsdiagnose (Joint Economic Forecast).

Financing 
More than half of the Institute's budget is derived from public grants, which DIW Berlin receives as research funding from the State of Berlin and the Federal Government in equal parts. This sum is supplemented by income from projects, research contracts with third parties, trustee memberships and donations. Because of its financial structure DIW Berlin is member of the Leibniz Association (WGL).

In 2022, news media reported critically about payments made by Uber to prominent academics and highlighted the role of a consultancy arm of DIW. DIW, in collaboration with Justus Haucap, had agreed to produce a study on “consumer benefits from a liberalisation of the German taxi market”, for what a news leak suggested was a fee of €48,000 plus VAT. Haucap launched the report at events for influencers and politicians in Berlin.

Publications 
Dissemination of information is fundamental to DIW Berlin. As a leading economic research institute, it seeks to supply the wider public with up-to-date economic and structural data, forecasts, research reports, and services in the field of quantitative economics. Research results are presented in the Institute's own publications and in publications edited in co-operation with the Institute.

Economic situation forecasts 
Forecasts about current and future trends in Germany, EU and world economy are published on a regular basis by DIW Berlin.

History 
1925 In July 1925  founds DIW Berlin, which is originally called Institute for Business Cycle Research, and becomes the first President.

1928 In the context of the Quarterly Journal of Economic Research, Arthur Hanau publishes his dissertation "The phenomenon of cyclical development" and becomes head of the agricultural market research in Germany. Using his concept of the "pork cycle" is still a popular way of explaining students of economics the relationship between demand and supply.

1933–1945 During the Nazi Regime, Wagemann is removed from his office. He is questioned several times by the Gestapo and even arrested for a while in 1942. By the end of 1943, the Institute for Business Cycle Research,  renamed in German Institute for Economic Research, is partially relocated to Feldberg, Mecklenburg.

1945 Postwar Berlin political leader Ferdinand Friedensburg
takes on being the President of the German Institute for Economic Research until 1968. Following the war, the main focus of economic research lies upon economic issues within the city of Berlin.

1950 The first Wochenbericht (Weekly Report) after the war is published, covering a detailed report about "Germany´ s economic situation at the end of 1945".

1956 The German Institute for Economic Research moves into a new building in Koenigin-Luise-Straße.

1960 For the first time, the so-called “Grundlinien der Wirtschaftsentwicklung”, forecasts about current and future trends in Germany, EU and world economy, are published. They are referring to the year of 1961.

1968  becomes new President of the German Institute for Economic Research.

1972 Newly established departments are the Department of Transportation, the Department of Public Finance and the Department of Money and Capital Markets.

1975 Karl Koenig takes on being  the President of the German Institute for Economic Research.

1979 The German Institute for Economic Research publishes the Wochenbericht „Eine mittelfristige Strategie zur Wiedergewinnung der Vollbeschaeftigung“, proposing strategies for re-establishing full employment in Germany. Taking this report into account, the federal government derives a programme for future investment in year 1977-1980, one of the very few programmes which consequence is a noticeable drop in German unemployment rates. Prof. Dr. Hans-Jürgen Krupp becomes new President of the German Institute for Economic Research.

1989 The Socio-Economic Panel Study (SOEP) is now part of the German Institute for Economic Research. The main focus of the service institution SOEP is on basic research and scientific services. The Socio-Economic Panel regularly surveys 10,000 private households in a representative longitudinal study. The data acquired is analysed within and outside the German Institute for Economic Research, the results are then used for the analysis of income and labour force developments.

1990 The German Institute for Economic Research disapproves of a monetary union with the former GDR. In the case of a monetary union, the only way for the GDR to compensate their difference in productivity would be a significant decrease of the wage level. A unification of wage levels would lead to mass dismissals and enormous business shutdowns. The GDR people would become welfare recipients of the Federal Republic of Germany.

1994 On behalf of Greenpeace, the German Institute for Economic Research analyses the economic consequences of an ecological fiscal reform. The model of ecotax, short for ecological taxation, has been enacted in Germany by means of three laws in the following years.

2000 Klaus F. Zimmermann becomes new President of the DIW. From now on, there are seven Research Departments. Thus, the DIW is able to react flexible to new respective current economic and social political topics. Main focus of economic research is now lying upon information society and competition, public economics and innovation. The Institute also aims at increasing its number of international cooperations and its participation in research networks worldwide.

2003 DIW Berlin publishes its first Konjunkturprognose (Economic Barometer), an up-to-date indicator of Germany's economic trends.

2006 With the founding of the DIW Graduate Center, the Institute dedicates itself to furthering the careers of young scientists.

2007 DIW Berlin relocates from Berlin-Dahlem to Mohrenstraße in Berlin-Mitte, marking a return to the city's government district.

2013 Marcel Fratzscher becomes new President of the DIW.

2016 The Berlin Economics Research Associates (BERA), a postdoctoral program funded by the Leibniz Association to promote the careers of young scientists, is established at DIW Berlin.
