FDA is Finally Gluten-Free

by OngjulianBrady Dennis reported in the Washington Post that after nine excruciating years FDA finally came up with a “gluten-free” standard. It took so long for the usual reasons, as Dennis explains in his article:

Alessio Fasano, director of the Center for Celiac Research at Massachusetts General Hospital, said the FDA took an “excruciating” amount of time to finalize its gluten-free definition in part because it had to consider a massive amount of research on celiac disease as well as varying opinions from activists who wanted even more stringent standards and industry officials who argued for more lenient requirements. In the end, he said, the agency struck the right balance.

The question that the article failed to ask was whether the FDA standard was even necessary. As Dennis points out, there are several independent private organizations that certify gluten-free products. Thus, not only do markets provide gluten-free certification, they also give consumers a choice on the standard’s stringency. Consumers who are highly sensitive to gluten can pick the labels that impose more stringent standards. Less sensitive consumers could choose products with higher gluten content.

Instead of fighting for nine long years for a single government imposed standard, why not let markets do what they do best – offer consumers better choices at lower prices?

The Economics of Regulation Part 2: Quantifying Regulation

I recently wrote about a new study from economists John Dawson and John Seater that shows that federal regulations have slowed economic growth in the US by an average of 2% per year.  The study was novel and important enough from my perspective that it deserved some detailed coverage.  In this post, which is part two of a three part series (part one here), I go into some detail on the various ways that economists measure regulation.  This will help put into context the measure that Dawson and Seater used, which is the main innovation of their study.  The third part of the series will discuss the endogenous growth model in which they used their new measure of regulation to estimate its effect on economic growth.

From the macroeconomic perspective, the main policy interventions—that is, instruments wielded in a way to change individual or firm behavior—used by governments are taxes and regulations.  Others might include spending/deficit spending and monetary policy in that list, but a large percentage of economics studies on interventions intended to change behavior have focused on taxes, for one simple reason: taxes are relatively easy to quantify.  As a result, we know a lot more about taxes than we do about regulations, even if much of that knowledge is not well implemented.  Economists can calculate changes to marginal tax rates caused by specific policies, and by simultaneously tracking outcomes such as changes in tax revenue and the behavior of taxed and untaxed groups, deduce specific numbers with which to characterize the consequences of those taxation policies.  In short, with taxes, you have specific dollar values or percentages to work with. With regulations, not so much.

In fact, the actual burden of regulation is notoriously hidden, especially when directly compared to taxes that attempt to achieve the same policy objective.  For example, since fuel economy regulations (called Corporate Average Fuel Economy, or CAFE, standards) were first implemented in the 1970s, it has been broadly recognized that the goal of reducing gasoline consumption could be more efficiently achieved through a gasoline tax rather than vehicle design or performance standards.  However, it is much easier for a politician to tell her constituents that she will make auto manufacturers build more fuel-efficient cars than to tell constituents that they now face higher gasoline prices because of a fuel tax.  In econospeak, taxes are salient to voters—remembered as important and costly—whereas regulations are not. Even when comparing taxes to taxes, some, such as property taxes, are apparently more salient than others, such as payroll taxes, as this recent study shows.  If some taxes that workers pay on a regular basis are relatively unnoticed, how much easier is it to hide a tax in the form of a regulation?  Indeed, it is arguably because regulations are uniquely opaque as policy instruments that all presidents since Jimmy Carter have required some form of benefit-cost analysis on new regulations prior to their enactment (note, however, that the average quality of those analyses is astonishingly low).  Of course, it is for these same obfuscatory qualities that politicians seem to prefer regulations to taxes.

Despite the inherent difficulty, scholars have been analyzing the consequences of regulation for decades, leading to a fairly large literature. Studies typically examine the causal effect of a unique regulation or a small collection of related regulations, such as air quality standards stemming from the Clean Air Act.  Compared to the thousands of actual regulations that are in effect, the regulation typically studied is relatively limited in scope, even if its effects can be far-reaching.  Because most studies on regulation focus only on one or perhaps a few specific regulations, there is a lot of room for more research to be done.  Specifically, improved metrics of regulation, especially metrics that can be used either in multi-industry microeconomic studies or in macroeconomic contexts, could help advance our understanding of the overall effect of all regulations.

With that goal in mind, some attempts have been made to more comprehensively measure regulation through the use of surveys and legal studies.  The most famous example is probably the Doing Business index from the World Bank, while perhaps the most widely used in academic studies is the Indicators of Product Market Regulation from the OECD.  Since 2003, the World Bank has produced the Doing Business Index, which combines survey data with observational data into a single number designed to tell how much it would cost to “do business,” e.g. set up a company, get construction permits, get electricity, register property, etc., in set of 185 countries.  The Doing Business index is perhaps most useful for identifying good practices to follow in early to middle stages of economic development, when property rights and other beneficial institutions can be created and strengthened.

The OECD’s Indicators of Product Market Regulation database focuses more narrowly on types of regulation that are more relevant to developed economies.  Specifically, the original OECD data considered only product market and employment protection regulations, both of which are measured at “economy-wide” level—meaning the OECD measured whether those types of regulations existed in a given country, regardless of whether they were applicable to only certain individuals or particular industries.  The OECD later extended the data by adding barriers to entry, public ownership, vertical integration, market structure, and price controls for a small subset of broadly defined industries (gas, electricity, post, telecommunications, passenger air transport, railways, and road freight).  The OECD develops its database by surveying government officials in several countries and aggregating their responses, with weightings, into several indexes.

By design, the OECD and Doing Business approaches do a good job of relating obscure macroeconomic data to actual people and businesses.  Consider the chart below, taken from the OECD description of how the Product Market Regulation database is created.  As I wrote last week and as the chart shows, the rather sanitized term “product market regulation” actually consists of several components that are directly relevant to a would-be entrepreneur (such as the opacity of a country’s licenses and permits system and administrative burdens for sole proprietorships) and to a consumer (such as price controls and barriers to foreign direct investment).  You can click on the chart below to see some of the other components that are considered in OECD’s product market regulation indicator.

Still, there are two major shortcomings of the OECD data (shortcomings that are equally applicable to similar indexes produced by the World Bank and others).  First, they cover relatively short time spans.  Changes in regulatory policy often require several years, if not decades, to implement, so the results of these changes may not be reflected in short time frames (to a degree, this can be overcome by measuring regulation for several different countries or different industries, so that results of different policies can be compared across countries or industries).

Second, and in my mind, more importantly, the Doing Business Index is not comprehensive.  Instead, it is focused on a few areas of regulation, and then only on whether regulations exist—not how complex or burdensome they are.  As Dawson and Seater explain:

[M]easures of regulation [such as the Doing Business Index and the OECD Indicators] generally proceed by constructing indices based on binary indicators of whether or not various kinds of regulation exist, assigning a value of 1 to each type of regulation that exists and a 0 to those that do not exist.  The index then is constructed as a weighted sum of all the binary indicators.  Such measures capture the existence of given types of regulation but cannot capture their extent or complexity.

Dawson and Seater go out of their way to mention at least twice that the OECD dataset ignores environmental and occupational health and safety regulations.  Theirs is a good point – in the US, at least, environmental regulations from the EPA alone accounted for about 15% of all restrictions published in federal regulations in 2010, and that percentage has consistently grown for the past decade, as can be seen in the graph below (created using data from RegData).  Occupational health and safety regulations take up a significant portion of the regulatory code as well.

env regs as percentage of total

In contrast, one could measure all federal regulations, not just a few select types.  But then the process requires some usage of the actual legal texts containing regulations.  There have been a few attempts to create all-inclusive time series measures of regulation based on the voluminous legal documents detailing regulatory activity at the federal level.   For the most part, studies have relied on the Federal Register, the government’s daily journal of newly proposed and final regulations.  For example, many scholars have counted pages in the Federal Register to test for the existence of the midnight regulations phenomenon—the observation that the administrations of outgoing presidents seem to produce abnormally large numbers of regulations during the lame-duck period

There are problems with using the Federal Register to measure regulation (I say this despite having used it in some of my own papers).  First and foremost, the Federal Register includes deregulatory activity.  When a regulatory agency eliminates words, paragraphs, or even entire chapters from the CFR, the agency has to notify the public of the changes.  The agency does this by printing a notice of proposed rulemaking in the Federal Register that explains the agencies intentions.  Then, once the public has had adequate time to comment on the agencies proposed actions, the agency has to publish a final rule in the Federal Register—another set of pages that detail the final actions the agency is taking.  Obviously, if one is counting pages published in the Federal Register and using that as a proxy for the growth of regulation, deregulatory activity that produces positive page counts would lead to incorrect measurements.  

Furthermore, pages published in the Federal Register may be a biased measure because the number of pages associated with individual rulemakings has increased over time as acts of Congress or executive orders have required more analyses. In his Ten-Thousand Commandments series, Wayne Crews mitigates this drawback to some degree by focusing only on pages devoted to final rules.  The Ten-Thousand Commandments series keeps track of both the annual number of final regulations published in the Federal Register and the annual number of Federal Register pages devoted to final regulations.

Dawson and Seater instead rely on the Code of Federal Regulations, another set of legal documents related to federal regulationsActually, the CFR would be better described as the books that contain the actual text of regulations in effect each year.  When a regulatory agency creates new regulations, or alters existing regulations, those changes are reflected in the next publication of the CFR.  Dawson and Seater collected data on the total number of pages in the CFR in each year from 1949 to 2005. I’ve graphed their data below.

dawson and seater cfr pages

*Dawson and Seater exclude Titles 1 – 3 and 32 from their total page counts because they argue that those Titles do not contain regulation, so comparing this graph with page count graphs produced elsewhere will show some discrepancies.

Perhaps the most significant advantage of the CFR over counting pages in the Federal Register is that it allows for decreases in regulations. However, using the CFR arguably has several advantages over indexes like the OECD product market regulation index and the World Bank Doing Business index.  First, using the CFR captures all federal regulation, not just a select few types.  Dawson and Seater point out:

Incomplete coverage leads to two problems: (1) omitted variables bias, and, in any time series study, (2) divergence between the time series behavior of subsets of regulation on the one hand and of total regulation on the other.

In other words, ignoring potentially important variables (such as environmental regulations) can cause estimates of the effect of regulation to be wrong.

Second, the number of pages in the CFR may reflect the complexity of regulations to some degree.  In contrast, the index metrics of regulation typically only consider whether a regulation exists—a binary variable equal to 1 or 0, with nothing in between.  Third, the CFR offers a long time series – almost three times as long as the OECD index, although it is shorter than the Federal Register time series.

Of course, there are downsides to using the CFR.  For one, it is possible that legal drafting standards and language norms have changed over the 57 years, which could introduce bias to their measure (Dawson and Seater brush this concern aside, but not convincingly in my opinion).  Second, the CFR is limited to only one country—the United States—whereas the OECD and World Bank products cover many countries.  Data on multiple countries (or multiple industries within a country, like RegData offers) allow comparisons of real-world outcomes and how they respond to different regulatory treatments.  In contrast, Dawson and Seater are limited to constructing a “counterfactual” economy – one that their model predicts would exist had regulations stayed at the level they were in 1949.  In my next post, I’ll go into more detail on the model they use to do this.

The Economics of Regulation Part 1: A New Study Shows That Regulatory Accumulation Hurts the Economy

In June, John Dawson and John Seater, economists at Appalachian State University and North Carolina State University, respectively, published a potentially important study (ungated version here) in the Journal of Economic Growth that shows the effects of regulatory accumulation on the US economy.  Several others have already summarized the study’s results (two examples here and here) with respect to how the accumulation of federal regulation caused substantial reductions in the growth rate of GDP.  So, while the results are important, I won’t dwell on them here.  The short summary is this: using a new measure of federal regulation in an endogenous growth model, Dawson and Seater find that, on average, federal regulation reduced economic growth in the US by about 2% annually in the period from 1949 to 2005.  Considering that economic growth is an exponential process, an average reduction of 2% over 57 years makes a big difference.  A relevant excerpt tells just how big of a difference:

 We can convert the reduction in output caused by regulation to more tangible terms by computing the dollar value of the loss involved.  […] In 2011, nominal GDP was $15.1 trillion.  Had regulation remained at its 1949 level, current GDP would have been about $53.9 trillion, an increase of $38.8 trillion.  With about 140 million households and 300 million people, an annual loss of $38.8 trillion converts to about $277,100 per household and $129,300 per person.

These are large numbers, but in fact they aren’t much different from what a bevy of previous studies have found about the effects of regulation.  The key differences between this study and most previous studies are the method of measuring regulation and the model used to estimate regulation’s effect on economic growth and total factor productivity.

In a multi-part series, I will focus on the tools that allowed Dawson and Seater to produce this study: 1. A new time series measure of total federal regulation, and 2. Models of endogenous growth.  My next post will go into detail on Dawson and Seater’s new time series measure of regulation, and compares it to other metrics that have been used.  Then I’ll follow up with a post discussing endogenous growth models, which consider that policy decisions can affect the accumulation of knowledge and the rates of innovation and entrepreneurship in an economy, and through these mechanisms affect economic growth.

Why should you care about something as obscure as a “time series measure of regulation” and “endogenous growth theory?”  Regulations—a form of law that lawyers call administrative law—create a hidden tax.  When the Department of Transportation creates new regulations that mandate that cars must become more fuel efficient, all cars become more expensive, in the same way that a tax on cars would make them more expensive.  Even worse, the accumulation of regulations over time stifle innovation, hinder entrepreneurship, and create unintended consequences by altering the prices of everyday purchases and activities.  For an example of hindering entrepreneurship, occupational licensing requirements in 17 states make it illegal for someone to braid hair for a living without first being licensed, a process which, in Pennsylvania at least, requires 300 hours of training, at least a 10th grade education, and passing a practical and a theory exam. Oh, and after you’ve paid for all that training, you still have to pay for a license.

And for an example of unintended consequences: Transportation Security Administration procedures in airports obviously slow down travel.  So now you have to leave work or home 30 minutes or even an hour earlier than you would have otherwise, and you lose the chance to spend another hour with your family or finishing some important project.  Furthermore, because of increased travel times when flying, some people choose to drive instead of fly.  Because driving involves a higher risk of accident and death than does flying, this shift, caused by regulation, of travelers from plane to car actually causes people to die (statistically speaking), as this paper showed.

Economists have realized the accumulation of regulation must be causing serious problems in the economy.  As a result, they have been trying to measure regulation in different ways, in order to include regulation in their models and better study its impact.  One famous measure of regulation, which I’ll discuss in more detail in my next post, is the OECD’s index of Product Market Regulation.  That rather sanitized term, “product market regulation,” actually consists of several components that are directly relevant to a would-be entrepreneur (such as the opacity of a country’s licenses and permits system and administrative burdens for sole proprietorships) and to a consumer (such as price controls, which can lead to shortages like we often see after hurricanes where anti-price gouging laws exist, and barriers to foreign direct investment, which could prevent multinational firms like Toyota from building a new facility and creating new jobs in a country).  But as you’ll see in the next post, that OECD measure (and many other measures) of regulation miss a lot of regulations that also directly affect every individual and business.  In any science, correct measurement is a necessary first step to empirical hypothesis testing.

Dawson and Seater have contributed a new measure of regulation that improves upon previously existing ones in many ways, although it also has its drawbacks.  And because their new measure of regulation offers many more years of observations than most other measures, it can be used in an endogenous growth model to estimate how regulation has affected the growth of the US economy.  Again, in endogenous growth models, policy decisions (such as how much regulation to create) affect economic growth if they affect the rates of accumulation of knowledge, innovation, and entrepreneurship. It’s by using their measure in an endogenous growth model that Dawson and Seater were able to estimate that individuals in the US would have been $129,300 richer if regulations had stayed at their 1949 level.  I’ll explain a bit more about endogenous growth theory in a second follow-up post.  But first things first—my next post will go into detail on measures of regulation and Dawson and Seater’s innovation.
