The Federal Reserve's balance sheet has undergone significant changes since 2007, reflecting its response to major economic crises. From a modest 0.9 trillion U.S. dollars at the end of 2007, it ballooned to approximately 6.76 trillion U.S. dollars by March 2025. This dramatic expansion, particularly during the 2008 financial crisis and the COVID-19 pandemic - both of which resulted in negative annual GDP growth in the U.S. - showcases the Fed's crucial role in stabilizing the economy through expansionary monetary policies. Impact on inflation and interest rates The Fed's expansionary measures, while aimed at stimulating economic growth, have had notable effects on inflation and interest rates. Following the quantitative easing in 2020, inflation in the United States reached eight percent in 2022, the highest since 1991. However, by November 2024, inflation had declined to 2.7 percent. Concurrently, the Federal Reserve implemented a series of interest rate hikes, with the rate peaking at 5.33 percent in August 2023, before the first rate cut since September 2021 occurred in September 2024. Financial implications for the Federal Reserve The expansion of the Fed's balance sheet and subsequent interest rate hikes have had significant financial implications. In 2023, the Fed reported a negative net income of 114.3 billion U.S. dollars, a stark contrast to the 58.84 billion U.S. dollars profit in 2022. This unprecedented shift was primarily due to rapidly rising interest rates, which caused the Fed's interest expenses to soar to over 281 billion U.S. dollars in 2023. Despite this, the Fed's net interest income on securities acquired through open market operations reached a record high of 174.53 billion U.S. dollars in the same year.

The U.S. federal funds effective rate underwent a dramatic reduction in early 2020 in response to the COVID-19 pandemic. The rate plummeted from 1.58 percent in February 2020 to 0.65 percent in March, and further decreased to 0.05 percent in April. This sharp reduction, accompanied by the Federal Reserve's quantitative easing program, was implemented to stabilize the economy during the global health crisis. After maintaining historically low rates for nearly two years, the Federal Reserve began a series of rate hikes in early 2022, with the rate moving from 0.33 percent in April 2022 to 5.33 percent in August 2023. The rate remained unchanged for over a year, before the Federal Reserve initiated its first rate cut in nearly three years in September 2024, bringing the rate to 5.13 percent. By December 2024, the rate was cut to 4.48 percent, signaling a shift in monetary policy in the second half of 2024. The first rate cut in 2025 then set the rate at 4.33 percent. What is the federal funds effective rate? The U.S. federal funds effective rate determines the interest rate paid by depository institutions, such as banks and credit unions, that lend reserve balances to other depository institutions overnight. Changing the effective rate in times of crisis is a common way to stimulate the economy, as it has a significant impact on the whole economy, such as economic growth, employment, and inflation. Central bank policy rates The adjustment of interest rates in response to the COVID-19 pandemic was a coordinated global effort. In early 2020, central banks worldwide implemented aggressive monetary easing policies to combat the economic crisis. The U.S. Federal Reserve's dramatic reduction of its federal funds rate - from 1.58 percent in February 2020 to 0.05 percent by April - mirrored similar actions taken by central banks globally. While these low rates remained in place throughout 2021, mounting inflationary pressures led to a synchronized tightening cycle beginning in 2022, with central banks pushing rates to multi-year highs. By mid-2024, as inflation moderated across major economies, central banks began implementing their first rate cuts in several years, with the U.S. Federal Reserve, Bank of England, and European Central Bank all easing monetary policy.

The inflation rate in the United States declined significantly between June 2022 and January 2025, despite rising inflationary pressures towards the end of 2024. The peak inflation rate was recorded in June 2022, at 9.1 percent. In August 2023, the Federal Reserve's interest rate hit its highest level during the observed period, at 5.33 percent, and remained unchanged until September 2024, when the Federal Reserve implemented its first rate cut since September 2021. By January 2025, the rate dropped to 4.33 percent, signalling a shift in monetary policy. What is the Federal Reserve interest rate? The Federal Reserve interest rate, or the federal funds rate, is the rate at which banks and credit unions lend to and borrow from each other. It is one of the Federal Reserve's key tools for maintaining strong employment rates, stable prices, and reasonable interest rates. The rate is determined by the Federal Reserve and adjusted eight times a year, though it can be changed through emergency meetings during times of crisis. The Fed doesn't directly control the interest rate but sets a target rate. It then uses open market operations to influence rates toward this target. Ways of measuring inflation Inflation is typically measured using several methods, with the most common being the Consumer Price Index (CPI). The CPI tracks the price of a fixed basket of goods and services over time, providing a measure of the price changes consumers face. At the end of 2023, the CPI in the United States was 158.11 percent, up from 153.12 a year earlier. A more business-focused measure is the producer price index (PPI), which represents the costs of firms.

The U.S. federal funds rate peaked in 2023 at its highest level since the 2007-08 financial crisis, reaching 5.33 percent by December 2023. A significant shift in monetary policy occurred in the second half of 2024, with the Federal Reserve implementing regular rate cuts. By December 2024, the rate had declined to 4.48 percent. What is a central bank rate? The federal funds rate determines the cost of overnight borrowing between banks, allowing them to maintain necessary cash reserves and ensure financial system liquidity. When this rate rises, banks become more inclined to hold rather than lend money, reducing the money supply. While this decreased lending slows economic activity, it helps control inflation by limiting the circulation of money in the economy. Historic perspective The federal funds rate historically follows cyclical patterns, falling during recessions and gradually rising during economic recoveries. Some central banks, notably the European Central Bank, went beyond traditional monetary policy by implementing both aggressive asset purchases and negative interest rates.

European Union central banks navigated a complex economic landscape between 2022 and 2025, with interest rates initially rising across member states. However, a pivotal shift occurred in late 2023 as most countries began lowering their rates, reflecting the delicate balance between controlling inflation and supporting economic growth. In the Euro area, the European Central Bank (ECB) led this trend by cutting interest rates from 4.5 percent to 3.15 percent in 2024, implementing four strategic rate reductions throughout the year. This approach was nearly universally adopted, with Poland being the sole EU country not reducing its rates during this period. Global context and policy shifts The interest rate changes in the EU mirror similar movements in other major economies. The United States, United Kingdom, and European Union central banks followed remarkably similar patterns from 2003 to 2024, responding to shared global economic conditions. After maintaining near-zero rates following the 2008 financial crisis and the COVID-19 pandemic, these institutions sharply raised rates in 2022 to combat surging inflation. By mid-2024, the European Central Bank and Bank of England initiated rate cuts, with the Federal Reserve following suit. Varied approaches within the EU Despite the overall trend, individual EU countries have adopted diverse strategies. Hungary, for instance, set the highest rate in the EU at 13 percent in September 2023, gradually reducing it to 6.5 percent by September 2024. In contrast, Sweden implemented the most aggressive cuts, lowering its rate to 2.25 percent by February 2025, the lowest among EU members. These divergent approaches highlight the unique economic challenges faced by each country and the flexibility required in monetary policy to address specific national circumstances.

The Federal Reserve's balance sheet ballooned following its announcement to carry out quantitative easing to increase the liquidity of U.S. banks in early 2020. The balance sheet continued to grow in the following period as well, with a downward trend in 2023. As of February 29, 2024, the Fed's balance sheet amounted to roughly 7.6 trillion U.S. dollars. The most drastic increase in the observed period took place in the first half of 2020. This measure was taken to increase the money supply and stimulate economic growth in the wake of the damage caused by the COVID-19 pandemic. The Federal Reserve was not the only institution that implemented an expansionary monetary policy in response to the pandemic. For instance, the European Central Bank expanded its money supply in March 2020 and kept doing so over the following months. How do central banks increase the amount of money in circulation? Central banks can increase the money circulating in the economy in many ways. For instance, they can decrease banks’ reserve requirements to stimulate lending or decrease the interest rates to reduce the cost of borrowing for commercial banks. Alternatively, central banks can engage in open market operations (OMO) and buy securities such as government bonds from commercial banks or institutions. By conducting open market operations, the Federal Reserve expanded its balance sheet by seven trillion U.S. dollars between 2007 and 2023. All these measures aim to increase bank loans to entrepreneurs and consumers in order to stimulate employment and economic growth. Impact of COVID-19 on the U.S. economy The COVID-19 pandemic had a tremendous impact on national economies worldwide, and the United States was no exception. During the early months of the crisis, many lost their jobs, mostly those in lower-income categories. As a consequence, many Americans found it difficult to pay their rent and cover basic household expenses. Furthermore, in April 2022, most small business owners claimed that the pandemic had a large or moderate negative effect on their businesses. Overall, the gross domestic product (GDP) of the United States decreased by roughly 2.2 percent in 2020. In the following years, however, it increased notably, surpassing 25 trillion U.S. dollars in 2022.

Policy interest rates in the U.S. and Europe are forecasted to decrease gradually between 2024 and 2027, following exceptional increases triggered by soaring inflation between 2021 and 2023. The U.S. federal funds rate stood at 5.38 percent at the end of 2023, the European Central Bank deposit rate at four percent, and the Swiss National Bank policy rate at 1.75 percent. With inflationary pressures stabilizing, policy interest rates are forecast to decrease in each observed region. The U.S. federal funds rate is expected to decrease to 3.5 percent, the ECB refi rate to 2.65 percent, the Bank of England bank rate to 3.33 percent, and the Swiss National Bank policy rate to 0.75 percent by 2025. An interesting aspect to note is the impact of these interest rate changes on various economic factors such as growth, employment, and inflation. The impact of central bank policy rates The U.S. federal funds effective rate, crucial in determining the interest rate paid by depository institutions, experienced drastic changes in response to the COVID-19 pandemic. The subsequent slight changes in the effective rate reflected the efforts to stimulate the economy and manage economic factors such as inflation. Such fluctuations in the federal funds rate have had a significant impact on the overall economy. The European Central Bank's decision to cut its fixed interest rate in June 2024 for the first time since 2016 marked a significant shift in attitude towards economic conditions. The reasons behind the fluctuations in the ECB's interest rate reflect its mandate to ensure price stability and manage inflation, shedding light on the complex interplay between interest rates and economic factors. Inflation and real interest rates The relationship between inflation and interest rates is critical in understanding the actions of central banks. Central banks' efforts to manage inflation through interest rate adjustments reveal the intricate balance between economic growth and inflation. Additionally, the concept of real interest rates, adjusted for inflation, provides valuable insights into the impact of inflation on the economy.

The U.S. bank prime loan rate has undergone significant fluctuations over the past three decades, reflecting broader economic trends and monetary policy decisions. From a high of 10.1 percent in 1990, the rate has seen periods of decline, stability, and recent increases. As of February 2025, the prime rate stood at 7.5 percent, marking a notable rise from the historic lows seen in the early 2020s. Federal Reserve's impact on lending rates The prime rate's trajectory closely mirrors changes in the federal funds rate, which serves as a key benchmark for the U.S. financial system. In 2023, the Federal Reserve implemented a series of rate hikes, pushing the federal funds target range to 5.25-5.5 percent by year-end. This aggressive monetary tightening was aimed at combating rising inflation, and its effects rippled through various lending rates, including the prime rate. Long-term investment outlook While short-term rates have risen, long-term investment yields have also seen changes. The 10-year U.S. Treasury bond, a benchmark for long-term interest rates, showed an average market yield of 2.13 percent in the second quarter of 2024, adjusted for constant maturity and inflation. This figure represents a recovery from negative real returns seen in 2021, reflecting shifting expectations for economic growth and inflation. The evolving yield environment has implications for both borrowers and investors, influencing decisions across the financial landscape.

The Volcker Shock was a period of historically high interest rates precipitated by Federal Reserve Chairperson Paul Volcker's decision to raise the central bank's key interest rate, the Fed funds effective rate, during the first three years of his term. Volcker was appointed chairperson of the Fed in August 1979 by President Jimmy Carter, as replacement for William Miller, who Carter had made his treasury secretary. Volcker was one of the most hawkish (supportive of tighter monetary policy to stem inflation) members of the Federal Reserve's committee, and quickly set about changing the course of monetary policy in the U.S. in order to quell inflation. The Volcker Shock is remembered for bringing an end to over a decade of high inflation in the United States, prompting a deep recession and high unemployment, and for spurring on debt defaults among developing countries in Latin America who had borrowed in U.S. dollars.

Monetary tightening and the recessions of the early '80s

Beginning in October 1979, Volcker's Fed tightened monetary policy by raising interest rates. This decision had the effect of depressing demand and slowing down the U.S. economy, as credit became more expensive for households and businesses. The Fed funds rate, the key overnight rate at which banks lend their excess reserves to each other, rose as high as 17.6 percent in early 1980. The rate was allowed to fall back below 10 percent following this first peak, however, due to worries that inflation was not falling fast enough, a second cycle of monetary tightening was embarked upon starting in August of 1980. The rate would reach its all-time peak in June of 1981, at 19.1 percent. The second recession sparked by these hikes was far deeper than the 1980 recession, with unemployment peaking at 10.8 percent in December 1980, the highest level since The Great Depression. This recession would drive inflation to a low point during Volcker's terms of 2.5 percent in August 1983.

The legacy of the Volcker Shock

By the end of Volcker's terms as Fed Chair, inflation was at a manageable rate of around four percent, while unemployment had fallen under six percent, as the economy grew and business confidence returned. While supporters of Volcker's actions point to these numbers as proof of the efficacy of his actions, critics have claimed that there were less harmful ways that inflation could have been brought under control. The recessions of the early 1980s are cited as accelerating deindustrialization in the U.S., as manufacturing jobs lost in 'rust belt' states such as Michigan, Ohio, and Pennsylvania never returned during the years of recovery. The Volcker Shock was also a driving factor behind the Latin American debt crises of the 1980s, as governments in the region defaulted on debts which they had incurred in U.S. dollars. Debates about the validity of using interest rate hikes to get inflation under control have recently re-emerged due to the inflationary pressures facing the U.S. following the Coronavirus pandemic and the Federal Reserve's subsequent decision to embark on a course of monetary tightening.

During the period beginning roughly in the mid-1980s until the Global Financial Crisis (2007-2008), the U.S. economy experienced a time of relative economic calm, with low inflation and consistent GDP growth. Compared with the turbulent economic era which had preceded it in the 1970s and the early 1980s, the lack of extreme fluctuations in the business cycle led some commentators to suggest that macroeconomic issues such as high inflation, long-term unemployment and financial crises were a thing of the past. Indeed, the President of the American Economic Association, Professor Robert Lucas, famously proclaimed in 2003 that "central problem of depression prevention has been solved, for all practical purposes". Ben Bernanke, the future chairman of the Federal Reserve during the Global Financial Crisis (GFC) and 2022 Nobel Prize in Economics recipient, coined the term 'the Great Moderation' to describe this era of newfound economic confidence. The era came to an abrupt end with the outbreak of the GFC in the Summer of 2007, as the U.S. financial system began to crash due to a downturn in the real estate market.

Causes of the Great Moderation, and its downfall

A number of factors have been cited as contributing to the Great Moderation including central bank monetary policies, the shift from manufacturing to services in the economy, improvements in information technology and management practices, as well as reduced energy prices. The period coincided with the term of Fed chairman Alan Greenspan (1987-2006), famous for the 'Greenspan put', a policy which meant that the Fed would proactively address downturns in the stock market using its monetary policy tools. These economic factors came to prominence at the same time as the end of the Cold War (1947-1991), with the U.S. attaining a new level of hegemony in global politics, as its main geopolitical rival, the Soviet Union, no longer existed. During the Great Moderation, the U.S. experienced a recession twice, between July 1990 and March 1991, and again from March 2001 tom November 2001, however, these relatively short recessions did not knock the U.S. off its growth path. The build up of household and corporate debt over the early 2000s eventually led to the Global Financial Crisis, as the bursting of the U.S. housing bubble in 2007 reverberated across the financial system, with a subsequent credit freeze and mass defaults.

In 2023, the Federal Reserve System maintained its position as the world's largest central bank, with its balance sheet assets growing to exceed 7.7 trillion U.S. dollars. Similarly, the People's Bank of China strengthened its second-place standing, with assets surpassing 6.4 trillion U.S. dollars. Notably, while these two giants saw asset increases, a contrasting trend emerged among other major central banks. Three of the five largest central banks experienced asset decreases in 2023, indicating a divergence in monetary policies or economic conditions across major economies.

Canada's inflation rate experienced significant fluctuations from 2018 to 2025. Inflation peaked at 8.1 percent in June 2022 before steadily declining to 1.9 percent by January 2025. In response to rising inflation between 2020 and 2022, the Bank of Canada implemented aggressive interest rate hikes. The bank rate reached a maximum of 5.25 percent in July 2023 and remained stable until June 2024. As inflationary pressures eased in the second half of 2024, the central bank reduced interest rates to 3.5 percent in December 2024. This pattern reflected broader global economic trends, with most advanced and emerging economies experiencing similar inflationary challenges and monetary policy adjustments. Global context of inflation and interest rates The Canadian experience aligns with the broader international trend of central banks raising policy rates to combat inflation. Between 2021 and 2023, nearly all advanced and emerging economies increased their central bank rates. However, a shift occurred in the latter half of 2024, with many countries, including Canada, beginning to lower rates. This change suggests a new phase in the global economic cycle and monetary policy approach. Notably, among surveyed countries, Russia maintained the highest interest rate in early 2025, while Japan had the lowest rate. Comparison with the United States The United States experienced a similar trajectory in inflation and interest rates. U.S. inflation peaked at 9.1 percent in June 2022, slightly higher than Canada's peak. The Federal Reserve responded with a series of rate hikes, reaching 5.33 percent in August 2023. This rate remained unchanged until September 2024, when the first cut since September 2021 was implemented. In contrast, Canada's bank rate peaked at 5.25 percent and began decreasing earlier, with cuts in June and July 2024. These differences highlight the nuanced approaches of central banks in managing their respective economies amid global inflationary pressures.

The net interest margin for the U.S. banking industry is expected to decline in 2025, after reaching its highest level since 2019 in 2024. In 2023, the net interest margin stood at 3.16 percent, and the forecast suggests a further increase to 3.24 percent in 2024. This trend is closely tied to central bank monetary policy. The Federal Reserve's aggressive interest rate hikes throughout 2022 and into 2023 have allowed banks to earn higher net interest margins by widening the spread between their lending rates and deposit costs. However, as the Fed begun cutting rates in September 2024, and is projected to continue doing so, this compression of the interest rate spread is expected to lead to a decline in the industry's overall net interest margin in 2025 and beyond.

The central bank policy rate in Japan stood at 0.5 percent in February 2025. In March 2024, the Bank of Japan raised short-term interest rates for the first time in 17 years, ending its negative interest rate policy. From August 2024 onwards, the central bank encouraged the uncollaterized overnight call rate to remain at 0.25 percent. A third rate hike to 0.5 percent was implemented in January 2025. In 2016, the Bank of Japan had introduced a policy of quantitative and qualitative monetary easing (QQE) with yield curve control, one component of which included controlling short-term and long-term interest rates through market operations.

Between January 2018 and February 2025, the United Kingdom's consumer price inflation rate showed notable volatility. The rate hit its lowest point at 0.5 percent in August 2020 and peaked at 9.6 percent in October 2022. By September 2024, inflation had moderated to 2.6 percent, but the following months saw inflation increase again. The Bank of England's interest rate policy closely tracked these inflationary trends. Rates remained low at 0.5-0.75 percent until April 2020, when they were reduced to 0.1 percent in response to economic challenges. A series of rate increases followed, reaching a peak of 5.25 percent from August 2023 to July 2024. The central bank then initiated rate cuts in August and November 2024, lowering the rate to 4.75 percent, signaling a potential shift in monetary policy. In February 2025, the Bank of England implemented another rate cut, setting the bank rate at 4.5 percent. Global context of inflation and interest rates The UK's experience reflects a broader international trend of rising inflation and subsequent central bank responses. From January 2022 to July 2024, advanced and emerging economies alike increased their policy rates to counter inflationary pressures. However, a shift began in late 2024, with many countries, including the UK, starting to lower rates. This change suggests a potential new phase in the global economic cycle and monetary policy approach. Comparison with other major economies The UK's monetary policy decisions align closely with those of other major economies. The United States, for instance, saw its federal funds rate peak at 5.33 percent in August 2023, mirroring the UK's rate trajectory. Similarly, central bank rates in the EU all increased drastically between 2022 and 2024. These synchronized movements reflect the global nature of inflationary pressures and the coordinated efforts of central banks to maintain economic stability. As with the UK, both the U.S. and EU began considering rate cuts in late 2024, signaling a potential shift in the global economic landscape.

In June 2024, the European Central Bank (ECB) began reducing its fixed interest rate for the first time since 2016, implementing a series of cuts. The rate decreased from 4.5 percent to 3.15 percent by year-end: a 0.25 percentage point cut in June, followed by additional reductions in September, October, and December. The central bank implemented another cut in early 2025, setting the rate at 2.9 percent. This marked a significant shift from the previous rate hike cycle, which began in July 2022 when the ECB raised rates to 0.5 percent and subsequently increased them almost monthly, reaching 4.5 percent by December 2023 - the highest level since the 2007-2008 global financial crisis. How does this ensure liquidity? Banks typically hold only a fraction of their capital in cash, measured by metrics like the Tier 1 capital ratio. Since this ratio is low, banks prefer to allocate most of their capital to revenue-generating loans. When their cash reserves fall too low, banks borrow from the ECB to cover short-term liquidity needs. On the other hand, commercial banks can also deposit excess funds with the ECB at a lower interest rate. Reasons for fluctuations
The ECB’s primary mandate is to maintain price stability. The Euro area inflation rate is, in theory, the key indicator guiding the ECB's actions. When the fixed interest rate is lower, commercial banks are more likely to borrow from the ECB, increasing the money supply and, in turn, driving inflation higher. When inflation rises, the ECB increases the fixed interest rate, which slows borrowing and helps to reduce inflation.

The exchange rate of the NZD/USD currency pair continued to decline over the course of 2022. As of March 13, 2025, the exchange rate reached approximately 0.57 U.S. dollars per New Zealand dollar. Being one of the most traded currency pairs in the world, the NZD/USD is closely connected to monetary policy from the Federal Reserve and the Reserve Bank of New Zealand. In early 2021, the yield on 10-year government bonds in the United States declined, which led to a weaker U.S. dollar against the New Zealand dollar.

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel was established in 1968 with an endowment from the Swedish central bank, the Riksbank. The award is administered by the Nobel Foundation, although it is not one of the Nobel Prizes, which were established in the will of Alfred Nobel. The award is chosen using the same method as the original Nobel Prizes and is awarded at the same ceremony as the prizes in Physics, Chemistry, Medicine and Literature every year in Stockholm, while The Nobel Peace Prize is awarded at a different ceremony in Oslo, Norway. Well known public figures who have received the award in the past include Milton Friedman of the University of Chicago in 1976 and Paul Krugman of Princeton University in 2008. The 2022 Prize The winners of the prize in 2022 were Ben Bernanke, Douglas Diamond and Philip Dybvig for "research on banks and financial crises". Ben Bernanke is most well known as the former chairman of the Federal Reserve, where he oversaw the response to the Global Financial Crisis, as well as for his academic work on the causes of the 1929 Wall Street Crash and The Great Depression, which he conducted largely at Princeton. Diamond and Dybvig are the authors of a formal theoretical model, the Diamond-Dybvig model, which pioneered the modelling of bank runs and financial panics. While the decision to award the prize to Bernanke, Diamond and Dybvig has been praised for recognizing their contributions to the theoretical and historical study of banking and its relation to financial panics, others have criticized the decision as their work is seen as ignoring the development of non-bank financial intermediaries, as well as criticizing Bernanke for his policy response to the financial crisis. Diamond is the University of Chicago's fourteenth recipient of the award, while Bernanke is Princeton's ninth and Dybvig is the Wahington University of St. Louis' second. The 2023 Prize The winner of the 2023 prize was Claudia Goldin of Harvard University for "having advanced our understanding of women's labor market outcomes". Goldin is only the third woman to receieve the Sveriges Riksbank prize - Elinor Ostrom being awarded in 2009 and Esther Duflo in 2019 - and the first woman to receive the prize as a sole winner. Goldin is an economic historian and a labor economist by training, whose work has focused on the historical development of women's participation in the labor market and the effects, both on the economy and on wider society, that this has had. Goldin's career-long research into these topics was summarised in her 2019 book Career and Family: Women's Century-Long Jouney toward Equity, which pointed to the unequal pressures which women and men haved faced when building careers over the past century, as women have had to balance their professional ambitions with their traditional role in the household. The 2024 Prize The winners of the 2024 prize were Daron Acemoglu, Simon Roberts Johnson, and James A. Robinson from the Massachusetts Institute of Technology and the University of Chicago, recognized for their work on "how institutions are formed and affect prosperity." Their research focuses on understanding the differences in how economic growth is shaped by the quality of institutions, demonstrating that inclusive institutions foster wealth creation by generating a virtuous circle of economic growth. Acemoglu and Roberts Johnson are the 11th recipients of the prize, placing MIT only four prizes behind the University of Chicago.
