Much like Alice in Alice in Wonderland, who drank from the “Drink Me” bottle and shrank to explore a world she couldn’t access before, nanoeconomics invites us to think small—delving into the granular details of individual behaviors and decisions. By getting “very small indeed,” we unlock insights that reveal inefficiencies, minimize waste, and address Economic… Read More »Let’s Get Small! Nanoeconomics to Address Economic Welfare Loss
Nanoeconomics: A Closer Look at Individual Behavior for Greater Economic Welfare
Just as Alice shrunk herself to explore a world of new perspectives in “Alice in Wonderland,” the concept of nanoeconomics urges us to scale down our thinking and delve into the intricate details of individual behaviors and decisions. This economic approach, focused on the ‘nano’ or ultra-microscopic level, presents us with a wealth of insights that can help reduce inefficiencies, minimize waste and tackle economic welfare loss.
Why Nanoeconomics?
The importance of understanding the economic behaviors and decisions of individuals cannot be overstated. Traditional macroeconomic models have often been critiqued for their inability to address the granular variations in human behavior, hence missing out on considerable opportunities for improvement. By observing these behaviors at a microscopic level, nanoeconomics allows us to identify and address inefficiencies and waste which would otherwise go unnoticed.
The Future of Nanoeconomic Analysis
The potential of nanoeconomics is immense. It offers a platform for economic models that are more realistic, precise, and nuanced. As technology continues to advance, tools such as big data analytics and Artificial Intelligence (AI) will further enhance our ability to observe and analyze individual economic behaviors on a granular level.
The insights gathered can be instrumental in identifying areas of economic waste and inefficiency and crafting policies to minimize these. Hence, it will play an essential role in addressing economic welfare issues both from an individual and broader economic perspective.
Actionable Insights from Nanoeconomics
Invest in Technological Tools
Organizations and governments should invest in technologies like AI and big data analytics that facilitate granular level analysis. These tools will empower them to unearth insights from individual-level data, enabling the design of strategies and policies that can optimize resource allocation and reduce economic waste.
Research and Policy Focus
Policy-makers and researchers should embrace nanoeconomics as a lens through which to examine and understand economic systems. Such analytical scrutiny can reveal valuable insights for crafting more precise and effective policies that account for individual differences and behaviors.
Focus on Education and Awareness
There is a need to create awareness about nanoeconomics at all levels of society. An understanding of how individual actions contribute to overall economic welfare can help individuals make informed decisions that lead to economic efficiency and waste reduction.
By thinking small—really small, we can unlock big insights in economics. The future of economics could well be ‘nano.’

Happy December, R friends!
One of my favorite traditions in the R community is the Advent of Code, a series of puzzles released at midnight EST from December 1st through 25th, to be solved through programming in the language of your choosing. I usually do a few of them each year, and once tried to do every single one at the moment it released!

This year, I know I won’t be able to do it daily, but I’m going to do as many as I can using just data.table
solutions.
I’ll allow myself to use other packages when there isn’t any data.table
equivalent, but my solutions must be as data.table
-y as possible.
I’m going to abuse the blog post structure and update this file throughout the week.
December 1st
Part One
d1 <- fread("day1_dat1.txt")
d1[, V1 := sort(V1)]
d1[, V2 := sort(V2)]
d1[, diff := abs(V1-V2)]
sum(d1$diff)
Part Two
d1[, similarity := sum(V1 == d1$V2)*V1, by = V1]
sum(d1$similarity)
December 2nd
Part One
d1 <- fread("day2_dat1.txt", fill = TRUE)
check_report <- function(vec) {
vec <- na.omit(vec)
has_neg <- vec < 0
has_pos <- vec > 0
inc_dec <- sum(has_neg) == length(vec) | sum(has_pos) == length(vec)
too_big <- max(abs(vec)) > 3
return(inc_dec & !too_big)
}
d1t <- transpose(d1)
deltas <- d1t[-nrow(d1t)] - d1t[2:nrow(d1t)]
res <- apply(deltas, 2, "check_report")
sum(res)
Part Two
test_reports <- function(dat) {
deltas <- dat[-nrow(dat)] - dat[2:nrow(dat)]
res <- apply(deltas, 2, "check_report")
res
}
res <- test_reports(d1t)
for (i in 1:nrow(d1t)) {
res <- res | test_reports(d1t[-i,])
}
sum(res)
Just for fun
I found the use of apply
deeply unsatisfying, even though it was fast, so just for fun:
d1t <- transpose(d1)
deltas <- d1t[-nrow(d1t)] - d1t[2:nrow(d1t)]
is_not_pos <- deltas <= 0
is_not_neg <- deltas >= 0
is_big <- abs(deltas) > 3
res_inc <- colSums(is_not_neg | is_big, na.rm = TRUE)
res_dec <- colSums(is_not_pos | is_big, na.rm = TRUE)
sum(res_inc == 0) + sum(res_dec == 0)
Yay.
