C. How Much Should a Prudent Student Be Willing to Pay for a JD?
Brace yourself. The exciting bottom line at the end of all that follows is that it depends on several factors.
Simkovic & McIntyre argue that a JD is underpriced, because the substantial majority of students armed with a JD can expect increased earnings over a BA with a net present value well in excess of the cost of the degree — even at full freight.
So far, I haven’t seen a convincing critique of the core of the study, although I do think there are a number of things at the margin where the authors have been unduly optimistic. For example, they assume law grads get a JD at 25, maximizing the lifetime earning stream; they assume law students earn an average of $24,000 in summer and term-time work during the 3 years of law school, which I think is high. The first is more significant than the second, although neither suffices to do more than put a small dent in the overall findings for most JD applicants. Another issue of note is that the study compares a JD to a no-JD, ie BA-only, world. It doesn’t compare a JD to an MBA or other advanced degree. Even taking all the study’s assumptions on board, the premium for alternate degrees might be higher than a JD.
But it’s one thing to set out some numbers about the distribution of national wages in the past, another to suggest they constitute a trend that will continue in the future, and still quite a different third thing to suggest that Alice and Bob can use these data to make a rational economic choice about how much they should be willing to pay for a JD. The headline numbers in the study are probably these:
Pre-Tax Present Value of JD Premium over BA (prior to calculating cost of tuition) 3% discount rate
||Men (in thousand $)
||Women (in thousand $)
source: Table 8
On the one hand, all these numbers are positive, so the prediction is that — even after one further subtracts the cost of tuition — a JD pays off for at least 75% of graduates and probably a lot more. On the other hand, some of these numbers are not that big, notably the 25th percentile number for men and women is pre-tax, so knock off another 30% or so, and more in some states. This starts to look less and less a winning proposition for anyone paying full private-school tuition and falling noticeably below that 25% mark. [Remember, that 25% is not Alice or Bob's class rank or their relative outcome in their law school class -- it's their relative salary outcome in the national JD class.]
Even if we assume a (perhaps slightly discounted?) version of the authors’ numbers accurately represents the historic earnings premium for a law degree for men and women at the 25th, 50th, and 75th percentile of the earnings spectrum for JD-holders, how can a prospective student today use this information to decide if a law degree is a good personal investment? (I should note here that the calculation is strictly economic; to the extent that the experience of law school and/or being a lawyer is perceived as fun or excruciating, as the case may be, these are external factors to the economic analysis — although they should in no way be external to the decision as to whether to pursue a JD. It is, however, fair to ask whether a law degree will be affordable even if law school or law practice is fun; or whether a law career will pay enough to make up for law school’s or law practice’s misery.)
Here is where the complexities begin. The authors give us a matrix of outcomes for representative men and women at three points on the earnings spectrum. We also know, from well-publicized anecdotes and blogs, if nothing else, that for some number of recent law graduates — the ones with large debt and lousy prospects — that the situation is currently dire. Indeed, it is the plight of these people, who likely number in the tens of thousands, that I think so inspires the anger of people who have been beating on Michael Simkovic and Frank McIntyre’s somewhat smug attempt at a refutation of the claim that the sky is falling.
What are the take-home lessons in ‘The Economic Value of a Law Degree’ for Alice and Bob? In other words how should Alice and Bob think about their potential earnings, and what should that mean for their willingness to shoulder law school expenses?
The paper uses aggregate figures. It doesn’t differentiate by law school. It ranks people by economic outcomes, which are only partly correlated with inputs — how well people did before law school, how prestigious a law school they go to, how well they do in whatever law school they attend. Since no potential 1L can know with great certainty how they will do in law school, nor what sort of legal (or non-legal) career they will find they desire, or be forced to settle for, much less the extent to which that success or failure will translate into income, Alice and Bob like all potential 1Ls must in effect run some simulations based on assumptions about their economic potential and their economic prospects.
The first thing Alice and Bob need to do is to think about what it is they might want to do. Yes, poeple’s ideas about careers often change radically in law school. But then oftentimes they don’t. Is their goal is primarily financial, or is it to be a crusading prosecutor or a defender of DREAMers and other immigrants? Some jobs pay a lot more than others, and if they aspire to one that isn’t highly paid, that may put limits on what they can afford to pay unless they have rich and generous relatives.
The next thing is to make a sober calculation about where one will fall in the national income distribution. This isn’t easy. It’s not a simple matter of plugging in LSATs into some formula based on a law school’s US News rank, and not only because those rankings have only limited meaning. Remember that about 1 in 5 law graduates doing legal work enjoyed even worse outcomes than the 25th percentile reported by Simkovic and McIntyre. At some point not too far from there — the bottom 10%?15%? — law school becomes an economic loser if you have to pay full freight, and at some point lower down (we have no real idea where but it is certainly there) it becomes economically dubious even if you get a full ride due to the opportunity costs.
If I were advising a student, I’d start with the extremes: if you are contemplating going to a top-three law school, it’s a no-brainer: you’ll have a great intellectual experience, and the odds of paying off whatever you have to pay are pretty good. Get a bit of a discount from a “top 14″ school and I think the odds are also excellent that (financially) you are getting a good deal; it’s quite likely this is also true at full freight unless you do (or interview) very badly.
Conversely, if you are going to a very-low-ranked law school — which I might define expansively to include a decent fraction of the law schools outside the USN top 144 — I’d encourage Alice and Bob to assume, unless they have a promise of a job in the family firm or they just need the degree to get a promotion in the organization where they currently work, that you will be in the bottom 25% percent of the distribution. Unless you have some reason to believe that this school has a lock on a strong regional market, beware.
That leaves many people in the middle. In order to make a rational economic calculation Alice and Bob need to make educated guesses about three things, two of which are hard to guess: 1) to what extent the Simkovic & McIntyre numbers should be discounted because of things knowable before starting school (such as starting law school later in life or carrying a lot of high-interest college debt); 2) Where they believe they are likely to fall in the post-JD income distribution, taking account of their taste for risk; 3) Whether the real rate of interest applicable to their circumstances will be more or less than 3%.
That last point is surprisingly important. Consider this back-of-the-envelope recalculation of the chart above. This one uses rounded post-tax numbers, and a 4% real (ie inflation-adjusted) interest rate instead of a 3% rate. This 4% rate more closely reflects what students who graduate with $150,000 of debt and up normally have to pay on the weighted average of their debt.
Present Value of JD Premium over BA (prior to calculating cost of tuition)
Post-Tax at 4% discount [based on combining tables 7, 8 & 9]
(Table 9/Table 7)*(Table 8)*(1-tax rate, see p. 43)
||Men (in thousand $)
||Women (in thousand $)
||(285/348)*316 * .75 =
|(285/348) * 352 * .75 =
||(482/606)*581 * .7 =
|(482/606) * 578 * .7 =
||(897/1098)*1151 * .65 =
|(897/1098)* 961 * .65 = 510
Now things look considerably more bleak for the students in the bottom quarter of the income distribution. Whether their JD is a good investment is acutely sensitive to how much it costs. A full-freight degree at a private law school will cost upwards of $130,000 (recall that the study assumes living expenses are the same as an alternate choice; it ignores moving costs too). All of a sudden that present value $200,000 (minus summer & term-time earnings, minus other adjustments) doesn’t look so great — and the lower the graduate falls below the 25th percentile on the income distribution, the worse it will get.
Even before that point, life can get very uncomfortable if you have a lot of undergraduate debt, especially in the early years when salaries are low but repayment is hitting as hard as ever. Economists figuring out the present discounted value of a degree ignore cash flow issues because they use a present discounted value that sums the values over a time series. They don’t ask if every year in the series is positive, but only whether the total is positive. Simkovic & McIntyre suggest that cash flow is an issue they can reasonably ignore because so few JD holders default on their student loans. They also say that,
Our estimates of interest rates faced by borrowers are probably too high —that is, the present value of the degree we calculate based on the figures in Table A1 will be too low—because we have not included tax incentives or generous loan forgiveness programs for low income borrowers. (p. 55, footnotes omitted)
Alice and Bob should, I think, be wary of these arguments. Here is where using aggregates hides a great deal of the important variation in the particular, and where the question for each Alice and Bob is the cost and the the value of their degree. Even if average debt is manageable for JDs as a class, some people, the ones with the most debt, will experience a serious cash flow issue in the early years after law school.
So the bottom line here is in fact quite predictable: Whether a JD is a good financial bet is a function of institutional prestige, the price of the degree net of grants and scholarships, regional variations in expected outcomes, special factors that alter value or opportunity cost (e.g. age or giving up a highly paid existing job), and law school outcome (career choice, actual honors, and class rank). All but one of these variables are, in theory, knowable in advance, and that one — law school outcome– should be estimated conservatively (see part I on the Dunning-Kruger effect).
In short, whether a JD is a good financial bet depends on all the things any sensible person would already have thought it depends on. The more debt you are taking on, the more cautiously you should weigh your options. The better the school you are going to, the lower the fees you are being charged, the more law school looks like a good bet. And you need to take a very realistic, even pessimistic, look at where you likely will fall in the class at the school of your choice. On the other hand, the suggestion that law school is a bad economic bet is — if Simkovic & McIntyre’s numbers hold up — likely not true for a substantial majority of would-be JD’s…but by no means all.
D. Policy Implications
Three policy implications flow from the above.
First, we don’t need any more bad law schools; indeed unless something changes to increase the market for legal services, from a strictly economic perspective (ignoring the possible social value of having more lawyers around to serve under-served populations’ needs) we might be better off with somewhat fewer.
Second, law school transparency is really important. Alice and Bob can only make good decisions about whether to sink a massive investment of time and money into a JD if the schools seeking their matriculation provide honest and easily comparable data about student outcomes.
Third, doing something about the undergraduate student debt crisis — such as returning to the norm of a free, or nearly free, public undergraduate education, would not only serve important goals of producing an educated and aware citizenry, but would have a knock-on effect on the JD valuation issue. The combination of high undergraduate debt with high law school debt may be particularly difficult to justify unless the student is acquiring a relatively valuable JD and/or is paying relatively little in tuition.
