*Who Pays No Tax?*

In the July Contemporary Economic Policy is “Who Pays No Tax? The Declining Fraction Paying income Taxes and Increasing Tax Progressivity” by David Splinter (Joint Committee on Taxation). Here is the abstract:

Using federal individual income tax data, this paper presents the first long‐run estimates of the fraction paying no income tax. Between 1985 and 2015, the fraction of working age adults paying no tax increased from 20% to 36%. A decomposition shows that almost all of this increase resulted from changes in tax policy, especially from more generous tax credits. Increasing tax progressivity over the last three decades also resulted from more generous tax credits. The substantial federal tax changes enacted in 2017 are forecasted to temporarily increase both the fraction paying no tax and individual income tax progressivity.

One interesting takeaway from the paper is the historical context of these figures. Of course, the income tax started out vary narrow, but after it broadened it has hovered in that 30-35% range much of the time. Here is the fraction paying no tax from Splinter’s Figure 1:


Splinter uses a shift-share decomposition  to attribute the fluctuations in the share of non-payers to tax policy changes, demographic changes, and income distribution. The big driver, as noted in the abstract, turns out to be the tax policy changes (converting 2015 tax burdens into 1985 counterfactual tax burdens with changes to the EITC, new tax credits, and indexing of personal exemptions and standard deductions. These policy changes seem to account for much, about 13 of the 16 points, of the increase from 1985 to 2015. Working age distributions and household formation don’t do much work.

For all the attention put on top marginal income tax rates, it is also quite interesting to observe the correlation between the fraction paying no tax and individual income tax progressivity (as measured by the Kakwani Index), as in Splinter’s Figure 6:


And yes, you are reading correctly that the TCJA increased individual income tax progressivity, as the big-ticket potentially regressive elements were in revisions to corporate income and estate taxes.

David Splinter has several interesting pieces along these lines for subjects related to income inequality and income mobility, so his website is worth checking out. Here is Vox coverage last year of his back-and-forth with Saez and Piketty.

July (2019) issue of Public Finance Review released

Here is the link to the issue. I found particularly interesting the replication study by Calabrese and Gupta, as well as the fact that almost 60 percent of Germans oppose taxing inherited wealth (Bischoff and Kusa). Titles, authors, and abstracts below:


Should Wealth Transfers Be Taxed? Evidence from a Representative German Survey
Ivo Bischoff and Nataliya Kusa
In a representative survey, German citizens are asked whether inherited wealth beyond a certain amount should be taxed. Almost 60 percent state that it should not be taxed. Building on this survey, we identify factors that predict this opposition to the taxation of inherited wealth. We find monetary self-interest, redistributive preferences, and the adherence to traditional values to matter. Women are more likely to oppose wealth transfer taxes. We account for interdependencies to other intrafamilial transfers. Subjects’ attitude toward wealth transfer taxes does not depend on their personal experience in giving long-term care. Yet subjects who expect the typical German family to reward intrafamilial caregiving through higher wealth transfers are less likely to oppose the taxation of inherited wealth. The opposite holds for subjects who expect these taxes to incentivize earlier inter vivos transfers.


Evading the Catastrophic Costs of Nursing Home Care: A Theoretical Inquiry
Gideon Yaniv
While many countries operate publicly funded programs to help care-needing elderly people finance the catastrophic costs of nursing home care, eligibility to public assistance may be means tested. To qualify for a means-tested program, applicants must first exhaust (spend down) their financial assets on privately paying for nursing home care, thereby wiping out their lifetime savings and children’s inheritance. They may naturally consider the possibility of hiding assets from the health agency, consequently shifting the financial burden to taxpayers. The present article adjusts two classical tax evasion models to capture the decision to evade the costs of nursing home care, focusing on the implications on the evaded costs and the program’s deficit of attempting to cope with the escalating costs of nursing home care by imposing a cost-sharing premium on the applicants’ adult children. Some insights on the socially optimal level of the cost-sharing premium are finally discussed.


Fiscal Decentralization, Budget Discipline, and Local Finance Reform in Russia’s Regions
Michael Alexeev, Nikolay Avxentyev, Arseny Mamedov, and Sergey G. Sinelnikov-Murylev
Using a panel of Russian regions, we estimate the link between intraregional fiscal decentralization and regional budget deficits. Although Russia’s regions are not as autonomous (either politically or fiscally) as regions in some other federal states, we obtain robust and statistically and economically significant results. Specifically, expenditure decentralization has a positive effect on consolidated regional budget balances, while transfer dependence of municipalities is associated with higher deficits. The impact of revenue decentralization depends on whether a regional government can use its tax revenue assignments with the same high degree of discretion that generally characterizes explicit fiscal transfers. We show that a 2009 local finance reform that limited the discretion of regional governments to assign regional tax revenue to municipalities has changed the effect of tax decentralization on budget discipline.


Preferences over Public Good, Political Delegation, and Leadership in Tax Competition
Rupayan Pal and Ajay Sharma
Leadership (sequential choice) and political delegation are two mechanisms suggested to restrict “race-to-the-bottom” in tax competition. In this article, we analyze whether these two mechanisms when combined together would lead to unilaterally higher taxation or not. We show that political delegation with leadership in tax competition not only restricts race-to-the-bottom but also mitigates the possibility of overprovision of public good. In sequential choice game, only the follower region delegates taxation power to the policy maker but not the leader region. This puts a check on intensity of tax competition and restricts the under provision of public good.

Replication Studies

A Replication of “Agency Problems of Excess Endowment Holdings in Not-for-profit Firms” (Journal of Accounting and Economics, 2006)
Thad D. Calabrese and Anubhav Gupta
Core, Guay, and Verdi explore whether excessive levels of cash (“endowments”) are associated with nonprofits’ growth in program spending and fixed assets, agency problems, or donors’ monitoring efforts. We replicate their finding that excess endowments are unrelated to growth in program spending. However, unlike the original article, we find that persistent excess endowments are associated with growth in fixed assets. Further, when we alter the model specification to better align with theory, we find excess endowments increase program expense ratios and lead to higher growth in program service spending as well as capital investment. We are also able to replicate the original article’s finding that excess endowments are related to higher CEO and management compensation. However, when we again alter the model specification, we find excess endowments are associated with compensation declines. Overall, we find weaker evidence of a relationship between excess endowments and agency problems than the original article.


A Replication Study of “Openness, Country Size, and Government Size” (Journal of Public Economics 2009)
Andrew Musau
Ram (Journal of Public Economics, 93, 213-218, 2009) questions the body of influential research suggesting that there is a negative association between country size and government size, and country size and openness, which may account for the positive association between openness and government size. Using data from the Penn World Table (PWT), he shows that while openness is positively related to government size, fixed-effects estimates show little evidence of the aforementioned negative associations. We replicate Ram’s results using his data set and a newer revised version of the same data set and find that the ensuing government size–openness association is dependent on the version of the PWT data and the composition of the sample. In addition, we find some evidence of a negative association between country size and government size in the larger sample, but there remains no clear association between openness and country size.


Reply to “A Replication Study of ‘Openness, Country Size, and Government Size’ (Journal of Public Economics 2009)”
Rati Ram
Andrew Musau is able to replicate almost exactly Ram’s estimates from Penn World Table 6.1. Like Ram, Musau is also unable to show a significant negative association between country size and openness and between country size and government size of the kind postulated by Alesina and Wacziarg. To shed further light on the issue, fixed-effects estimates of the three core regressions are obtained from the widely used World Bank data for 174 countries covering the period 1990–2015. The estimates show a highly significant positive association between openness and government size, further reinforcing Ram’s estimates and those from Musau’s 189-country Penn World Table 7.1 sample. While the new country size estimates in openness and government size regressions are negative, the latter lacks significance at any meaningful level. Therefore, the substantive conclusion remains the same as indicated by Ram; while the predominance of evidence supports Rodrik’s thesis of a positive association between openness and government size, statistically significant evidence is lacking to support the Alesina–Wacziarg proposition that the aforesaid positive association is due to a combination of the negative association between country size and openness and between country size and government size.

*Political Budget Cycles and the Civil Service*

One of my internal motivations for starting this blog was to have a commitment device for staying current and broad in the public finance literature. One of the surprises that has come of this venture is the amount of good research on political budget cycles, a subject that I thought was basically dead. A year ago, I would have thought political budget cycle research was basically non-existent and what remained likely to be uninteresting.

The July issue of JPubE posses another example of how wrong I was in “Political Budget Cycles and the Civil Service: Evidence from Highway Spending in US States” by David Bostashvili (Amazon) and Gergely Ujhelyi (University of Houston). Here is the abstract

We study political budget cycles in infrastructure spending that are conditional on bureaucratic organization. Bureaucrats can facilitate or hinder politicians’ ability to engage in voter-friendly spending around elections. To test this idea, we use civil service reforms undertaken by US states in the second half of the 20th century to study political budget cycles in highway spending under civil service and patronage. We find that under patronage, highway spending is 12% higher in election years and 9% higher in the year before an election. By contrast, under civil service highway spending is essentially smooth over the electoral cycle. These findings provide a novel way through which civil service rules can stabilize government activity.

Of course if you’re still with me, you’re wondering how the authors define and identify “patronage” and “merit” systems in the states. The answer is that the authors are actually studying  the adoption of merit system adopted throughout the 20th century that mimicked legislation at the state level. These acts included a competitive civil service exam, prohibited mandatory political services from employees, and established a bipartisan civil service commission. Therefore, “patronage” systems are states that did not adopt those laws. Here is a neat preliminary figure the presents per capita highway spending over the state electoral cycle from 1960-1995 in the 44 states with 4-year election cycles:


And if you compare the 11 states that switch during their study period from patronage to merit, here is how they compare before and after:


The rest of the paper goes on to show that this analysis holds up when you use a regression to control for other factors so that you get these graphs but with confidence intervals.

Score one for the Deep State.

Fiscal Limits with Voter Overrides

A prominent feature of subnational governments in the US is that they face legal constraints that prevent them from raising taxes or spending levels by any amount they may want. Indiana, for instance, restricts the local budget levy to a fraction of statewide nonfarm personal income growth. There are ways to circumvent these limits, however, and a popular way is to allow for voter overrides. You will recognize this as something like “the city can increase its budget up to 5% without voter approval this year, but anything more than that will require a special voter referendum.”

A recent JPubE paper by Stephen Coate and Ross Milton investigates the optimal determination of the limits in the presence of voter overrides.

This paper studies optimal fiscal limits in the context of a simple political economy model. A politician chooses the level of taxation for a representative citizen but is biased in favor of higher taxes. A constitutional designer sets a tax limit before the citizen’s preferred level of taxation is fully known. The politician is allowed to override the limit with the citizen’s approval. The paper solves for the optimal limit and explains how it is impacted by the possibility of overrides. The paper also shows that the citizen’s welfare can be enhanced if the designer imposes a limit on the politician’s override proposals.

The authors take inspiration from the literature on the delegation problem, where an agent must choose a policy that impacts both principal and agent’s payoffs. The payoffs depend on a state of nature, which prior to the policy choice will only be observed by the agent. Here, the policy is the level of spending or taxation that impacts welfare of a representative citizen (the principal) and the politician (the agent) is assumed to be biased in favor of a larger spending. Coate and Milton extend this to determining the optimal fiscal limit, which sets up their main contribution: comparing to a extension where voters can override the limit. This is done by allowing the politician to propose a policy in excess of the limit which is subjected to the vote. If voters pass the proposal, this is adopted; if not they offer a second proposal which respects the limit. The primary tool here for the politician is agenda-setting power over the citizen. Here is their summary of the main results:

There are three main results. First, with overrides, the optimal limit is at least as stringent as without. […] Second, with overrides, the typical monotonic relationship in delegation models between the agent’s bias and the tightness of the limit does not necessarily arise. […] Third, the institutional arrangement consisting of a limit and an override provision can always be strictly dominated by an arrangement that also specifies an override limit. Limiting the proposal the politician can make at the override stage prevents him from fully exploiting his agenda-setting power. The availability of an override limit changes the calculus underlying the regular limit. Since a limit increases the benefit of overrides, the regular limit is often tighter, making overrides more likely.

Call for Papers: VIII Ibero-American Conference on Local Financing (Mexico City)

The conference is October 1-2, 2019, hosted by the Universidad Iberoamericana and the Center for Economic Reserach and Teaching (CIDE).

The Conference continues a joint initiative of academics and policy specialists in local finance that began in Spain in 2011 and subsequently continued in Argentina (2013), Brazil (2014), Chile (2015) , Spain (2016), Argentina (2017), and Colombia (2018).

The objective of the conference is to present a maximum of twelve research papers on topics related to: 1.Fiscal decentralization; 2. Efficiency and quality of sub-national welfare expenditures including public investments; 3. Subnational  tax collection; 4. Management of Sub-national Governments; 5. Debt and subnational financing; and 6. Subnational financing frameworks for climate change within Ibero-American countries (Latin America and Spain).

In previous conferences, a total of 92 papers have been presented, showing a great thematic and geographical coverage, adding to the growing importance of local finances in Latin America and the Caribbean, both in the research agendas and in policy matters. The ultimate goal is to create evidence based policy to improve fiscal systems in the region.

The call for papers seeks research and unpublished studies that, within the general themes listed above, to disclose new findings and research advances on local financing issues in Ibero-American countries. Through an academic selection committee, research papers selected will be invited to present their work in Mexico City October 1 and 2, 2019. This includes travel support and lodging for one professional to participate in the conference.

While the sessions seek to exchange views and policy innovations,  professionals of think tanks, national budget authorities such as national ministries of finance, international organizations, local public officials, and finally academics and students of public policy and public administration, economics public and public finances will likely participate in the audience.  Additionally, a half day will be devoted to a “Workshop on the Challenges of Local Financing” and ideas will be exchanged on the definition of research topics to be addressed in the next JIFL.

Fill out this form to participate.

I appreciate professor Heidi Jane Smith (Universidad Iberoamericana) for both the notice of the conference and the translation above. Do note that the conference itself will be in Spanish.

*Higher Pay, Worse Outcomes? The Impact of Mayoral Wages on Local Government Quality in Peru*

That is the title of an article by Ricardo Pique (Ryerson University) in the Journal of Public Economics. Does raising salary for mayors result in better mayoral performance, or gentrify the pool of candidates in some way? Here is Pique on the evidence from Peru:

In this paper, I study how wages earned by local politicians affect local government quality. To identify the effects, I use caps imposed by the Peruvian central government on mayoral wages as an excluded instrument. The results show that mayoral wages do not improve government performance. In particular, there is a negative impact on public investment implementation and on performance goals set by the central government. Moreover, there is no evidence of a positive effect on politician selection, municipal bureaucratic capacity, and political effort. Wages do strongly affect the local political landscape, increasing political competition and reducing political support for the mayor. These changes may help explain the drop in performance as local authorities may face more political obstacles when implementing their policy agenda. Overall, the results show that higher politician wages need not improve local government quality.

To circumvent endogeneity, the instrument for actual wages paid is the maximum amount the Peruvian central government sets for mayoral wages (through a population based step function). So the identification is going to arrive from populations narrowly passing (or not) the threshold that allows them to offer higher mayoral wages.

Of course, evaluating public sector performance is an inherently difficult thing to do. There is a large cocktail of dependent variables, and they consistently show that they are negatively affected by getting the inducement into a higher wage. One of the author’s preferred outcome measures is a budget execution rate. According to Pique, Peruvian mayors are significant administrators of investment projects backed by the federal government, so he uses the share of the investment budget that was actually spent (“execution rate”). This was not very intuitive to me, so I’m just going to pull the explanation from footnote 38 on page 9:

Unlike other policy outcomes such as total revenue, investment implementation is within the mayor’s control. Local authorities are constantly pressured by both the central government and the local population to carry out their budgeted investment projects. Both national and local newspapers produce articles comparing the relative performance of local authorities in matters of public investment implementation. Failure to implement budgeted public investment projects can be particularly dangerous amid a weak institutional and political context. Ponce and McClintock (2014) show that low levels of implementation are correlated with more social protests.

Here is a sampling of some of the main results, and of course the study has many robustness checks with a particular interest on whether this gets at performance:


So, broadly, the effect on performance is negative. The question is why, and one possibility is that it undesirably changes the selection of mayors, so a variety of mayor and candidate for mayor attributes are effected by the wage offer. This does not appear to be the case:


A number of other plausible outcomes are investigated, including bureaucratic capacity, political effort, and political competition, and it seems like political competition (increased number of parties, reduction in winner’s vote share, reduction in public sector experience) is the most plausible explanation in terms of why a change occurs, though it is not terribly clear why this reduces performance rather than increasing it. Pique says the pattern is perhaps most supportive of creating a rising obstructionist party at the local level and this might be a Peru specific outcome. The negative effects on getting mayors with public sector experience shows up in a variety of ways, and I’m somewhat inclined to think of that as an important finding towards explaining what is happening. In my opinion, public service motivation is underrated by the public (albeit overrated by public administration scholars)

There is much of interest and to admire in the paper. For background reading, perhaps consider Besley and Case’s (1995) QJE paper “Does Electoral Accountability Affect Economic Policy Choices?“.
