Behavioral economics integrates ideas from psychology and economics to understand how individuals really make choices, instead of how they must make decisions according to standard financial theories. Instead of logical agents, the majority of people are creatures of routine and impulse who make choices based on gut feeling and mental biases. Yet, even this progressive field typically still treats human beings as essentially computer-like in their info processing, not catching the full scope of the intricacy of human financial decision-making.
Economics has traditionally viewed people as rational optimizers, perfectly processing information to make the very best choices within their restrictions like the obeying automatons that they are. It took economists a while before they realized thats not at all how individuals make monetary choices, which is how behavioral economics happened.
Lived experiences, like hyperinflation, substantially rewire the brain, affecting monetary decisions in the future and possibly across whole generations.
Her research, for example, shows that substantial social and economic events, such as run-away inflation, can literally rewire the brain, resulting in long-lasting results on financial decision-making. This reprogramming continues even after the financial environment supports, influencing peoples responses to similar scenarios in the future.
Ulrike Malmendier, professor of financing and economics at the University of California, Berkeley, argues through her multi-decade research that lived experiences have an extensive experience on all economic behavior.
Behavioral economics shows people make monetary choices based upon routines, instincts, and mental biases, not solely reasonable thinking.
Bridging economics with neuroscience, researchers show how the experience of high inflation highly influences future homeownership and investment choices– even in times of low inflation and in absolutely various financial environments.
The experience and expectation of inflation
The last couple of years considering that the pandemic have been rough for everybody. Besides the awful death and human suffering owed to a pandemic unmatched in the last century, the events that unfolded since 2020 have sent rippling shockwaves into the worldwide economy. As if the supply chain shocks and subsequent cash printing werent worrying enough, then came Russias invasion of Ukraine which triggered energy costs to surge– and with them, the cost for virtually whatever else.
” What this new research about the effects of experience states is that if I endure a crisis– for instance, a high inflation crisis– that modifications me. That activates something in me, some worries. If I see rates and taxes that keep increasing, and Ive endured that for a while, it rewires my brain. It actually does. In fact, neuroscience tells us this. And we need to take that into account in economics,” Malmendier told ZME Science throughout an interview at the Falling Walls conference in Berlin.
The outcome has actually been really high inflation whose effects on the economy might stick around on for several years to come– even after inflation is brought back under control. Thats because not just do rates surge during a high-inflation environment, however also peoples fears, anxiety, and issues.
” Theres this view that when we are out of this inflation duration and inflation is back at 2%, whatever will be back to typical. To assume that all the people in the nation will function as in the past is simply wrong due to the fact that we have actually been rewired. We have actually been impacted.”
Simply put, theres a big distinction between the tough, cold numbers and charts that main banks reveal and how individuals view inflation in their everyday lives. When Fed chair Gerome Powell goes on TV discussing “soft landings” and how inflation is “cooling”, a single mama doing grocery shopping might pertain to a various conclusion. Ultimately, this subjective experience impacts inflation expectations, incredibly complicating the characteristics at play and throwing a wrench into economists fancy mathematical designs.
Youths of Gen Z, who have never gone through something like unlike their grandparents and moms and dads, are especially vulnerable. They might have ended up being completely scarred and afraid costs will continue to rise, which might affect their monetary choices for the rest of their lives.

The injury of inflation– and its rippling results

The German individuals who lived through these terrible events were scarred for life, completely altering their relationship with money and financing in general. Extremely, traditional economics hasnt thought about these important long-lasting results.
Amid this chaos, Germans struggled to understand what was taking place to their nation and why. They naturally questioned the ability of the state to keep things under control, which set the stage for Adolf Hitlers takeover in 1933– and we all understand what followed next.
Like all Germans, Malmendier grew up with the specter of inflation and what it can do to peoples livelihoods. In 1923, the Weimar Republic economy collapsed, activating a disastrous spiral of hyperinflation. In January 1923, a United States dollar expense 17,000 marks. In December, the currency exchange rate peaked at 4.2 trillion marks to the dollar– a shocking 2.5 billion percent increase.
Banknotes from last month were utilized by children as toys like Monopoly cash, while their moms and dads utilized their Papiermark (the currency of the Weimar Republic) to light the fire. Countless individuals found themselves bankrupt and struggling to make ends as their paper money was worth less than toilet tissue. The middle class was completely wiped out. For many, it was merely useless to bring cash anymore, so they turned to bartering.

It was common to see consumers hauling containers, bags, and even wheelbarrows complete of banknotes to pay for groceries or simple products. In some circumstances, individuals didnt bother to count cash anymore– weighing it was much more efficient.
The long-lasting memory of inflation
” The problem is it doesnt work,” says Malmendier.
” Theyre in a different country now. And still, you see in their financial decision-making, that they put a lot of weight on their previous experiences. If they come, state, from Argentina, with great deals of high inflation, they constantly attempt to protect their cash. And so thats a truly fine example for how these experiences really impact and rewire you, even if you know its not pertinent,” states Malmendier.

In a 2023 study released in the Journal of Finance, Malmendier and Alexandra Steiny Wellsjo from the University of California San Diego investigated how previous direct exposure to high inflation impacts own a home. Financial investment in buying a home and property, in general, is highly motivated by protecting ones wealth from currency decline.
Whenever inflation rises beyond the norm– which is anything above the “healthy” inflation rate of 2% per year– reserve banks roll up their sleeves and start pushing levers to tone it down. Normally, they play with the rates of interest and the cash supply. The expectation is that when this delicate balancing act succeeds and inflation is back under 2%, consumer habits will be back to normal.
The scientists discovered a strong connection between previous high inflation rates and higher homeownership. In Europe, nations with historically high inflation saw higher homeownership, with 50% of homeowners mentioning inflation defense as an essential motive. Likewise, immigrants in the U.S. from high-inflation nations likewise showed greater homeownership rates, suggesting that previous inflation experiences significantly influence real estate choices, even in brand-new financial environments. This is especially informative because it reveals that even after moving to a country with a totally different economic environment and housing market, the previous experience of inflation is still entrenched in peoples minds.
Motivated by the Weimar hyperinflation and its behavior-altering results, Malmendier studied other historic high inflation occasions, from Americas double-digit inflation from the 1970s and 1980s to the more current run-away inflation streak in Argentina. This research study revealed a global pattern that revealed living through inflation can significantly alter the way choose to spend, conserve, and obtain cash, regardless of the nation.
” Over and over, you see, independent of the decade or the nation you take a look at, that people whose lives have been identified by a great deal of high inflation, they continue to cope with that fear, even when the inflation is not there.”
The neuroscience of experiencing a financial decline
Both synaptic tagging and LTP explain why certain experiences, especially those that are emotionally charged or significant, like monetary crises, have a long-lasting influence on behavior.
The researchers also found that these effects are mediated by a recency predisposition. Current experiences have a more powerful impact on individuals expectations and risk-taking habits compared to earlier life experiences.
” A veteran who lives in Germany or the US might hear a loud noise, state of a car starting. To them, it seems like a bomb coming down. You understand theres no danger, yet you have this immediate reaction as if that terrible occasion was happening again.”
In neuroscience, this phenomenon is known as “synaptic tagging” and it is vital to finding out and memory formation. It discusses how specific experiences, mentally charged or especially considerable ones, leave a long lasting imprint on our brains.
Financial crises, market booms, or declines– these arent simply short lived news items. The bottom line is that these substantial financial dramas engrave themselves into our brains, producing strong, tagged synaptic connections that affect our future monetary habits.
In a 2021 study published in Review of Finance, Malmendier revealed that “Depression Babies” (people who matured during the Great Depression when the stock market crashed catastrophically) showed a substantially lower rate of stock market participation compared to later generations.
Individuals who experience betrayal or abuse may establish ingrained trust problems. Somebody who underwent traumatic experiences that included physical danger, such as being robbed or battling in war, can develop a heightened startle reaction and hypervigilance. We understand from psychiatry that distressing occasions can have lasting impacts on individuals, so its quite interesting that our economic models are just starting to overtake the science.
The traumatic financial experience of the Great Depression would have developed strong synaptic connections, making these memories more prominent and persistent in decision-making. In this case, losing a great deal of cash at the stock market makes people weary to purchase the future, just like enduring inflation can make people really protective of their money.
What does seeing increasingly higher prices at the gas pump and supermarket do the human brain? Whenever we have a brand-new experience, the brain forms new neural connections or synapses. When we experience the same thing all over once again, these connections are strengthened.
Another carefully associated phenomenon is long-lasting potentiation (LTP); a long-lasting enhancement in signal transmission in between 2 nerve cells that arises from their simultaneous stimulation. This procedure is likewise thought to underlie learning and memory.
Experience results are observed even among extremely educated and specialized experts, consisting of professional decision-makers and professionals in their fields. This even consists of lenders, who ought to know better. Henry (Heinrich) Wallich was born in the early 1900s in Berlin in a family of lenders.
How long and how seriously we experience a particular monetary slump, such as high inflation, matters a lot. The longer time gas pump costs keep increasing, the greater the risk that the inflationary event becomes engraved in peoples brains, says Malmendier. When the experience ends up being lasting, there might be extreme effects for the economy.
Nevertheless, the most noteworthy aspect of Wallichs period is the reality that to this day he holds the record for the most dissents (27) in the Feds board conferences. Wallich would usually object to monetary policy changes, alerting that inflation was around the corner– even when it wasnt a genuine concern.
These phenomena are looped by the overarching style of neuroplasticity, a key principle in neuroscience that refers to the brains capability to rearrange itself by forming new neural connections, reorganizing brain pathways, and even forming new nerve cells throughout life.
When a synapse is “tagged” following specific activities, it marks the area for later protein synthesis, vital for forming lasting memories. The proteins synthesized at these tagged sites enhance the synaptic connections, cementing the memory.

As a teenager, Wallich endured the Weimar Republics notorious run-away inflation before immigrating to the United States, where he followed in his parents steps and accomplished an effective career in the monetary industry. Wallich ultimately served as among the governors of the Federal Reserve Board from 1974 to 1986, a position in which he served with dignity.
” This sort of rewiring occurs also with economic trauma and events like the Weimar run-away inflation, however likewise the Great Depression in the United States or the pandemic. These are all terrible events, and we have to take this evidence, this neuropsychiatry evidence, seriously,” says Malmendier.
Wallich just could not shake off the specter of inflation, which he experienced in a various country abroad years earlier, despite the fact that he was a Fed governor. Why? Because his experience of financial injury made him act crazily at certain times.
In this context, neuroplasticity merely teaches us that people financial behaviors and mindsets are never static but are shaped and improved by their experiences. Experiencing a monetary crisis can lead to the development of brand-new neural paths associated with risk hostility or cautious investing.
Understanding all this
“The concept of neuroplasticity says that inflation scarring has long-lasting effects, but it also says that when the times are great once again for enough time, you rewire again and things will get much better,” Malmendier states.
“This whole concept of Gen X, Gen Y, Gen Z, Millennials, why is it? Why do we believe generations, individuals born around the same time, behave similarly in specific ways? Well, they have common experiences that have shaped them. Whichs what policymakers need to take into consideration,” Malmendier says.
Financial policy modifications, like those concerning inflation control, are vital, however they should be matched by noticeable modifications in individualss everyday lives. The real litmus test for any policy is its concrete influence on the ground– at the supermarket, the gas pump, and in the wallets of individuals. Peoples understanding of the economy can in some cases produce a self-fulfilling prediction.
While crises leave long-lasting results, these are not set in stone. Neuroplasticity suggests that our brain paths– and consequently our behavior– constantly change with experience. Its a two-way street. Positive and stable financial conditions over time can assist rewire individualss behaviors and attitudes, slowly reducing the impact of previous injuries.
This fresh neuroscience perspective on behavioral economics urges a reassessing of economic models and financial policy. It suggests that to really comprehend financial decision-making, we must think about the experiential and emotional elements, not simply the reasonable or educational aspects.
When immediate changes in lived experience are not possible, media and interaction can play crucial roles. Malmendier recommends moving away from dry financial policy statements to more relatable, experiential forms of interaction. The Central Bank of Jamaica, for example, uses reggae tunes to discuss inflation; a creative method to making financial principles more accessible and appealing.
” Theres this view that when we are out of this inflation period and inflation is back at 2%, everything will be back to regular. Whenever inflation increases beyond the norm– which is anything above the “healthy” inflation rate of 2% per year– main banks roll up their sleeves and start pressing levers to tone it down. In Europe, nations with traditionally high inflation saw greater homeownership, with 50% of homeowners pointing out inflation defense as a key intention. Immigrants in the U.S. from high-inflation countries likewise showed higher homeownership rates, recommending that previous inflation experiences considerably influence real estate choices, even in new financial environments. How long and how significantly we experience a certain financial downturn, such as high inflation, matters a lot.
Malmendier, who typically encourages German decision-makers and lenders in the European Central Bank, says it all starts with awareness. Current worldwide occasions, like the COVID-19 pandemic and the energy crisis, have actually left individuals more significantly worried and mindful about cost hikes, health concerns, and an unsteady expert landscape. This brand-new state of mind, Malmendier argues, need to be a critical factor to consider in policy formula.
A crucial obstacle for policymakers is addressing the scarring left by such occasions. Many individuals end up being extremely conservative in their economic choices post-crisis, such as saving exceedingly rather than purchasing themselves. To counter this, Malmendier recommends policies that tangibly show a return to normalcy, consequently assisting to rewire peoples economic behavior.
