AI's Impact on Productivity and Innovation

February 11, 2025 / 14:43

This episode of The Ripple Effect features Daniel Rock, an Assistant Professor at the Wharton School, discussing the impact of artificial intelligence on productivity, the challenges of measuring its effects, and the importance of complementary innovations.

Rock explains the concept of productivity in economics, emphasizing that it's not just about reducing resources but also about increasing output. He discusses the paradox of transformative technologies like AI, which may take time to show their full potential.

He outlines four areas of potential impact: false hopes regarding AI's capabilities, mismeasurement of economic gains, rent dissipation where benefits accrue to a small group, and the lag in restructuring organizations to effectively implement AI.

Rock also highlights the role of user experience in AI adoption, noting that tools like ChatGPT have made AI more accessible. He stresses the importance of hiring skilled talent and making complementary investments to maximize AI's effectiveness.

In concluding remarks, Rock expresses optimism about the future of AI in the workforce, suggesting that while there will be challenges, there are also opportunities for enhancing productivity and job satisfaction.

Daniel Rock: That's a really fascinating point. I mean, you think about the value of an OpenAI or Anthropic, even a Microsoft,
00:00:05
Google— you know, whoever's building it, Llama— like, a lot of the value of those companies is in the complementary
00:00:12
investments that their customers are making. Or, like, the ecosystem at large is making. That's really interesting,
00:00:17
right? Like the— they get more valuable as their customers and as their consumers learn how to integrate that toolkit. So I
00:00:25
think that's something that'll take a little while, but they're well aware of it too.
00:00:29
You know, they're trying to make it easier to use. - Welcome to <i>The Ripple Effect</i>,
00:00:33
the podcast that takes you on a journey through the minds of Wharton faculty. I'm your host, Dan
00:00:38
Loney, and in each episode, we'll be diving deep into the inspiration behind the groundbreaking research that
00:00:44
Wharton professors have conducted and exploring how their findings resonate with the world today.
00:00:51
Dan Loney: Well, when we think about innovation these days, there's a good chance that
00:00:54
artificial intelligence is going to come into the conversation. Even though it's been around for some time, it only now feels
00:01:02
like the majority of the public at large are seeing the impact of artificial intelligence in our lives. Daniel Rock is an
00:01:10
Assistant Professor of Operations, Information and Decisions here at the Wharton School. He and colleagues have
00:01:14
looked at how AI can impact something like productivity. Dan, great to have you here today. Thanks for your time.
00:01:20
Great to be here. Thanks for having me. So when I bring up AI, doesn't it seem like productivity kind of is a— a
00:01:27
natural— a natural first thing for people to think about? Oh, absolutely. And I think when we talk about productivity, it's important to
00:01:35
define terms here. For economists, productivity can be a few different things. It can be how much output per worker
00:01:41
you have, how much revenue per unit of input, but generally, all of it points to one big idea, which is, what are the
00:01:48
number of outputs we get per unit of input? So it's not, you know, how do we cut jobs, necessarily, or reduce the resource use. It's
00:01:56
also, how do we create more? And I think with these tools empowering people to do, you know, greater and more
00:02:02
interesting things, productivity in the long run has to kind of be positively impacted by what we can do with them.
00:02:08
- Would you say that, though— that there's a paradox when you think of this?
00:02:11
Yeah, sure. I think here's— here's the core thing with a sufficiently transformative technology, what economists
00:02:17
would call a general purpose technology. That is, it's pervasive, it improves over time, and then it kind of
00:02:23
necessitates and spawns complementary innovation. That is the other stuff you need to build to get this stuff to go.
00:02:30
So, yeah, there's a lag. It takes a long time to build up those additional assets, to reconfigure your organization,
00:02:36
to train people to use stuff. Over time, that's going to pay off in a big way, and we're seeing people make huge
00:02:41
investments in that. But it's not going to be, right off the bat, super powerful. Actually, it's funny with AI, there are
00:02:48
some applications that are right off the bat super powerful, but the long run implications are going to take a while to play
00:02:54
out, I think. - You have four areas of potential impact that you've come up with in the work that
00:03:00
you've done, the first being false hopes. Explain that a little bit. Oh yeah. So this is the explanation for the paradox. So, why
00:03:06
it takes a while. So I already preempted what I think is going on. But yes, there is the— there is the chance, right— this is
00:03:12
sort of a Bob Gordon view. I don't want to put too many words in his mouth, but, you know,
00:03:17
AI just isn't that big a deal. Or you could broaden this to say any technology just isn't that big a
00:03:23
deal. And we see lots of promise and hype, but it's just never going to materialize. That's a consistent way to view the world
00:03:31
in the early stages, if you don't know what's going to happen. But then you do have to, you know, change tack if you see
00:03:36
the benefits start to show up. I think with AI, we're starting to see that a bit. So that's number one.
00:03:41
The second one is mismeasurement. So this is kind of— there's some folks in Silicon
00:03:46
Valley who say this, and there's some evidence that this might be going on too. The idea here is that the gains are real. They're
00:03:53
happening, but we're not capturing them properly in the economic statistics. And I think this— the folks at the BLS and
00:04:01
the BEA do a really great job of trying to measure the economy. You know, where it might be tougher to measure things is
00:04:08
like, you know, Google's free. I asked my MBAs, would you rather have, you know, search or indoor plumbing? And you know, after
00:04:18
trying to wriggle out of that conundrum, many of them will still pick search over indoor plumbing. I'm kind of with them
00:04:24
on that one. - That's probably a good idea. Yeah. It gets cold in Philly, but not too cold, - Exactly.
00:04:29
So that's the second one. We could be mismeasuring things. And yes, there are some
00:04:32
cases where that may be the case. But in general, you have to make an argument for why it's different now. What changed to
00:04:39
make us worse at measurement, given what the economy is producing? And I think that's a tougher case. My co-author, Chad
00:04:44
Syverson at University of Chicago, has kind of disposed that argument. At least, you know, up until 2017 or so.
00:04:52
So that's the second one. The third one is sort of a rent dissipation argument. What does that mean? It's, the gains are
00:04:58
real, but they're accruing to a really small proportion of people in the economy. They're taking all of the gains, and
00:05:06
nobody else is seeing anything there. I think you could make an argument that a lot of that is still happening, but it would
00:05:12
have to be really enormous to take away the gains from the technology, given the expectations. And then the last
00:05:18
one, which we just discussed, restructuring and implementation lags. The stuff can take a while. We see a lot of promise,
00:05:25
but let's not confuse a clear view for a short walk. It's going to take a long time to implement this stuff.
00:05:30
So is the expectation, then, with where we are kind of currently, that we're still going to see innovation coming from other
00:05:37
areas to kind of complement what is, I think a lot of people believe, the core of— of what AI is right now?
00:05:44
Yeah, absolutely. I think that's that's already happening in a lot of areas. One of the really cool things about AI is— I don't
00:05:52
know if you you code, or if you if you use coding assistance, but the fact that these tools— the software you need to augment
00:06:01
them, to augment the AI tools, can be partially written with AI help. So we can— we really get in this nice, like, flywheel,
00:06:09
where you use AI to improve the sorts of tooling you need to make AI more effective.
00:06:15
That's— when I talk with companies, I'm like, "Are you guys doing this? Because you should be."
00:06:19
It's very helpful. There's an element that you talk about in this paper, about the added
00:06:25
costs being a type of capital that can be just part of the build out, I guess, correct?
00:06:32
Yeah, absolutely. When you have these adjustment costs or fixed costs of investment, these are things like the training or
00:06:39
intangible capital, or even the culture around how you build an organization that— that works with machine learning or AI
00:06:46
software. Like, this is a different type of software. It creates output that's non- deterministic, or maybe a little
00:06:54
bit fuzzier. It's not perfect every time, it's not cookie cutter. That's a mindset shift, too. You can't expect the same
00:07:00
results as you could with— with ordinary kind of rules-based software. So you have to pay that upfront cost, or maybe even
00:07:07
ongoing cost, to keep people in the loop, to structure your organization processes properly. And then what you— what you get
00:07:14
out of that is, you know, competitive advantage, basically. You can do things other companies can't, if you
00:07:20
crack that. - Sure. - Yeah. And obviously, part of that also probably fills into,
00:07:25
with the companies that are in the development of AI, the value that those companies have— you know, that that is a significant
00:07:33
beneficial capital component that they have to their companies, which, you know,
00:07:38
obviously is larger than other companies. Sure. That's a really fascinating point. I mean, you think about
00:07:42
the value of an OpenAI or Anthropic, even a Microsoft, Google— you know, whoever's building it, Llama— like, a lot
00:07:48
of the value of those companies is in the complementary investments that their customers are making. Or, like, the
00:07:54
ecosystem at large is making. That's really interesting, right? Like the— they get more valuable as their customers and
00:08:01
as their consumers learn how to integrate that toolkit. So I think that's— that's something that will take a little while,
00:08:08
but they're well aware of it too. You know, they're trying to make it easier to use. In some sense, ChatGPT is more of a UX
00:08:13
innovation. The playground existed. You could use stuff before, but ChatGPT just, like showed people, "Hey, you can—you
00:08:21
can really engage with these models and do something cool." I massively updated how important I thought UX was after I saw the
00:08:29
success of that app. So where we are right now then, you mentioned about some of the
00:08:34
metrics that will come into play here. It feels like we're still at a point where the development of some of those metrics is kind
00:08:42
of either— it either hasn't happened or it's ongoing right now, and so it may be hard to truly gauge the value or the
00:08:51
component of productivity, especially when we don't have the dynamics fully tweaked to what we need, right?
00:08:58
Yes, I agree with that. Though what makes AI, this wave of software, a little bit easier to do a good job there is, we're
00:09:06
using the last wave of IT to instrument it, right? So we have software to track the software. Before, I mean, the best you
00:09:13
could do, best you could hope for, was surveys of some kind, like, say, in the early '90s. Now we can scale up those efforts.
00:09:19
You can track sort of what some of my colleagues called "digital exhaust", right? You connect to APIs for companies, you can see
00:09:26
how they're changing what they're doing. You know, there's little pockets. This is like this big iceberg, and we're
00:09:32
seeing just the tip of it. But you can use those sort of points where we can see the tip of the iceberg and how it's changing as
00:09:41
a way to gauge what's going on. And a concrete example is something— you know, something I've done in my own work. I've
00:09:46
tracked how many people with AI skills are being hired company by company, assuming that if you're hiring people to do this,
00:09:52
you're probably building out all the other complements to make them effective. And, you know, that's— we're trying to measure
00:09:58
the— kind of the size of the— the investments on that front, which Which for many companies, is probably the way you need to do it, is
00:10:04
bring on the talent before you actually do the level of implementation to get to that point, so you have people who understand it
00:10:11
going— going— going into the process. 100%. You can't get away from— from labor markets and those
00:10:18
complementary investments. If you do AI well, then you probably did data science well before. If you did data science
00:10:24
well, you probably did the cloud well before. There's a whole stacking of these technologies. It actually makes AI super
00:10:29
concentrated in— in only a few firms right now. And it's a little bit, you know— a little bit of an explanation where that
00:10:35
might be coming from. But yeah, you're bottlenecked in three potential areas. It's either talent or data or compute right
00:10:43
now. But you mix those three things together in the right proportions, and you start to get, you know,
00:10:49
AI internal capabilities. What do you think, then, doing this research helped you to better
00:10:55
understand about where we are going, and that connection between AI and productivity? - Yeah.
00:11:02
So I started to think, what are the ingredients inside of a company that would generate productivity? Like, how— where
00:11:10
does it come from? And there's a few models that colleagues in other places have put together that I can use as sort of
00:11:16
workhorse models. There's sort of the task-based approach. There are researchers like David Auter and Daron Acemoglu at MIT
00:11:24
who have used this heavily. The idea is like, let's break down a job into bundle of tasks and track all those tasks. Those
00:11:30
tasks or those bundles are changing. I think the more change you see at that level, the more of an indication you
00:11:37
have that something is different now. So that's one early kind of check you can do to see what's going on. So I'm working on some
00:11:44
of that, looking at job postings with a few colleagues. And then there's kind of a perspective that Tim Bresnahan at Stanford
00:11:53
as well as Joshua Gans, Avi Goldfarb and Ajay Agrawal at University of Toronto have kind of put forth. It's the sense that
00:12:02
nobody's ever lost their job to task-based automation. It's not happening task by task, necessarily, or change isn't
00:12:08
happening task by task. It's happening at the system level. So when we change the direction in what's possible with a model,
00:12:16
like, I can discover new drugs with these tools, or I can— I mean, I can't. But I can make pretty lousy images or paintings
00:12:26
that I couldn't do before. I'll stop there with my new capabilities. But like, as— as you give people these new
00:12:32
capabilities, you redesign the system, and that new system's got different demands for people. Different demands for capital.
00:12:38
- Right. - So let's see if, like, there are companies making big changes saying "We're going to reconfigure this module." It's
00:12:43
kind of hard to do that if things are moving really quickly. You don't have certainty. You don't feel like
00:12:47
you're standing on solid ground when you do that. Does it feel, like, then— I'll finish up on this. Does it feel like
00:12:53
that where we are with AI and the workforce right now, that obviously AI is going to play a significant role, but the human
00:13:02
component will be there. And to a degree, maybe even the human component becomes kind of even more of a learning experience as
00:13:09
we move forward, because of how AI is kind of guiding the ship a little bit here.
00:13:13
Yeah, I get accused of being an optimist on this point, so I strongly agree with that. But I do think there are, of course,
00:13:19
going to be pockets where things go better or things go worse. One thing I've grown fond of saying recently is that we can't
00:13:26
get away from labor markets. So the— I will say, you know, perhaps it's a little bit of a stretch. I don't want to get too
00:13:32
far out of my skis here. But the augmentation versus automation debate matters at some unit of analysis. But at the individual,
00:13:41
like, you know, worker or manager making a decision about where to deploy the technology— you can augment someone that can
00:13:47
do the job of 20 people, and if the company doesn't want 20 people to do it, then that's not great news. For the workers, that
00:13:54
is. On the other hand, you can automate things that people hate doing and refocus their work on to other stuff where demand
00:14:01
expands. So these are choices that companies and managers and workers can make. They're not foregone conclusions. And I
00:14:08
think I've— I have confidence in the— you know, the talent of people out there in the world to make good choices there, and,
00:14:15
you know, ultimately end up in a more fulfilling sort of work configuration scenario.
