And we have good evidence for this approach, as I explain in this FreedomWorks discussion.
But I’m sharing the part about spending caps because it fits perfectly with some new research from Veronique de Rugy and Jack Salmon of the Mercatus Center.
They point out that America faces a grim fiscal future, but suggest that fiscal rules may be part of the solution.
…the federal budget process as it exists today has proven inadequate…it is a great way to enable politicians to do what they want to do (cater to interest groups) while avoiding what they don’t want to do (living within their means). […]The negative consequence emerging from this chaos and the resulting failure to follow budget rules is an unremitting expansion of the size and scope of government… With countries around the world experiencing growing debt-to-GDP ratios, resultant stagnation in economic growth, and, in extreme cases, default on debts, academics have been paying an increasing amount of attention to the potential of rules toward restraining unsustainable deficit spending. […]The good news is that the evidence suggests that these fiscal rules are broadly effective at restraining deficit spending. […]The bad news is that not all fiscal rules are effective in restraining government profligacy and curtailing debt growth.
The authors are right. Some fiscal rules don’t work very well.
As I stated in the interview, balanced budget requirements tend to be ineffective.
Spending caps, by contrast, have a decent track record.
The Mercatus study looks at Hong Kong.
Hong Kong…might actually represent the gold standard of good fiscal policy. …Hong Kong’s Financial Secretary, Mr. John Tsang, explained, “Our commitment to small government demands strong fiscal discipline. . . . It is my responsibility to keep expenditure growth commensurate with growth in our GDP.” …in Hong Kong it’s actually a constitutional requirement: Article 107 requires that the government should strive to achieve a fiscal balance, avoid deficit, and more importantly, make sure government spending doesn’t grow faster than the growth of the economy. …Hong Kong’s spending-to-GDP ratio has fluctuated between 14 and 20 percent since the 1990s, its debt as a share of GDP is zero, social welfare spending remains steady at less than 3 percent of GDP.
I’ve also praised Hong Kong’s fiscal policy.
Now let’s look at what the authors wrote about Switzerland.
Swiss politicians are not allowed to increase spending faster than average revenue growth over a multiyear period (as calculated by the Swiss Federal Department of Finance), which confines spending growth to a rate no higher than the rate of inflation plus population growth. The Swiss debt brake rule is significant in that it appeals to economists and policymakers on both sides of the aisle. Advocates for fiscal restraint support this rule because it is effectively a spending cap, while social democrats support the rule as it allows for deficit spending during recessionary periods. …There’s no arguing with the results: Annual spending growth fell from an average of 4.3 percent to 2.5 percent since the rule was implemented. Also, in 10 out of the past 14 years, Switzerland has had budget surpluses, while deficits have remained rare and small… At the same time, the Swiss debt-to-GDP ratio has fallen from almost 60 percent in 2003 to around 42 percent in 2017.
Once again, I say amen.
Switzerland’s spending cap is a big success.
Here’s Figure 1 from the study, which shows a big drop in Swiss government debt. I’ve augmented the chart with OECD data to focus on something even more important – which is that the burden of spending (which started very low by European standards) has declined since the debt brake was implemented.
Last but not least, let’s look at the Danish example.
In 2014 Denmark implemented The Budget Act to ensure more efficient management of public expenditures. The act is aimed at ensuring a balance or surplus on the general government balance sheet, as well as appropriate expenditure management at all levels of government. In practice, the rule sets a limit of 0.5 percent of GDP on the structural budget deficit. Policymakers decided that managing fiscal policy on the basis of a balanced structural budget would lead to an appropriate fiscal position in the long term. They also designed the system to take discretion out of their own hands by making the cuts automatic. In addition to structural deficit rules, the Budget Act introduces four-year rolling expenditure ceilings. These ceilings set legally binding limits for spending at all levels of government and for each program. If one program spends under its cap, any money not spent cannot be reallocated to another program.
I guess this is time for a triple-amen.
The economic case for spending caps is ironclad.
The problem is that it’s an uphill climb from a political perspective.
Politicians prefer legislative spending caps. After all (as we saw in 2013, 2015, 2018, and this year), those can be evaded with a simple majority, so long as there’s a profligate president who approves higher spending levels.
And those caps have never applied to entitlements, which are the part of the budget that eventually will bankrupt the nation.
So why wouldn't public choice-motivated lawmakers actually allow a serious and comprehensive spending cap to become part of the Constitution?
