Broken Expectations: Robert E. Hall and Uruguay’s Fiscal Maze

Hall’s permanent-income hypothesis and rational expectations provide a framework for examining spending, taxes, debt and fiscal credibility in Uruguay.

FROM HALL TO ODDONE
Broken Expectations: An Analysis Through Robert E. Hall’s Theory and Uruguay’s Fiscal Maze
By Dr. Nelson Jorge Mosco Castellano

The recent awarding of the Nobel Prize in Economics to Robert E. Hall and Michael Woodford has once again brought an uncomfortable truth for economic policymakers to the fore: macroeconomics and microeconomics (two sides of the same coin) do not operate through voluntarist decrees or accounting illusions, but through the individual decisions households and firms make according to their expectations.
The cornerstone of Hall’s model —the celebrated “random walk” of consumption and the permanent-income hypothesis— shows that rational economic agents do not respond to optimistic government announcements, but to the actual credibility of the rules of the game.
Applying this theoretical framework to the reality of the economic management led by Gabriel Oddone reveals a troubling dissonance.
Far from consolidating a scenario of stability, recent fiscal decisions reveal a vicious circle in which tax increases, rather than correcting structural imbalances, deepen uncertainty, erode citizens’ permanent income and feed a chronic deficit sustained by greater indebtedness.

The Miscalculation and the Permanent-Income Fallacy

One of the most criticized aspects of the current economic management lies in the repeated failure to meet the growth targets projected in the budget, a failure that, instead of being corrected, was aggravated by more spending.
A miscalculation that, far from being cushioned by fiscal prudence, is dangerously extending into the next Budget Review —and keeps growing and growing.
From Robert E. Hall’s perspective, when a government systematically misses its macroeconomic projections and resorts to tax increases to plug budget gaps, it generates what theory calls a negative information shock.
Families and firms perceive that the State lacks a credible fiscal anchor in the form of a national debt ceiling.
Faced with the certainty that future income is uncertain and that fiscal voracity will increase tomorrow to finance today’s inefficiencies, economic agents reduce discretionary consumption and postpone investment.
The attempt to offset falling activity or cash shortfalls through tax increases ignores Hall’s premise: squeezing taxpayers when permanent income is under pressure destroys the incentive to save and further slows gross domestic product.

Increasing Spending Against Reality

The most agonizing paradox of the current economic policy of the “left-wing liberal” minister is the persistent increase in public spending despite the failure to meet growth targets.
“There is no political mandate for a drastic cut in public spending,” Gabriel Oddone. And he not only failed to cut shameless public spending, but increased i
And he tempered it: “There are not enough resources for unlimited expansions of spending, and constraints require public finances to be managed rigorously, balancing social demands with fiscal viability.”
He also attended the “Social Dialogue” and supported the State confiscation of workers’ retirement savings in the AFAPs. Money that it had already spent financing public debt, as the market later warned him, summoning him to a broader realism by allowing AFAPs to invest abroad.

In any economic model grounded in the microeconomics of stabilization, a downward deviation in output growth requires a proportional containment of spending to preserve the State’s solvency.
However, persisting in expanding spending while real revenues collapse relative to budget projections destroys intertemporal confidence.
Under the approach of Ricardian equivalence and Hall’s postulates, citizens and financial markets know perfectly well that unfunded current spending is not a “stimulus”, but an unpaid bill that will be shifted into the future in the form of higher taxes or greater inflation.
The direct result of this asymmetry is the loss of institutional certainty.

Debt as a Refuge: A Mortgage on Expectations

When growth projections are not met and the upward rigidity of spending persists, the fiscal gap is inevitably papered over with one instrument: the growth of public debt. In addition comes the unconstitutional tax of inflation, which strips away present and future purchasing power.
For rational expectations theory, borrowing to sustain current imbalances without credible structural reforms is equivalent to shooting oneself in the foot.
Domestic and international investors assess country risk not by ministerial speeches, but by the consistency between the debt trajectory and the economy’s real capacity to generate wealth.
When debt grows because budget projections fail and spending is not adjusted, the risk of a future forced adjustment —the famous “collapse of expectations”— soars.
Gabriel Oddone’s economic policy now faces the severe scrutiny of economic reality.
The insistence on fiscally squeezing an economy that is not growing, combined with the inability to bring spending under control and the inertia of rising debt, shows that the most elementary lessons of modern economic science, recently honored in the figure of Robert E. Hall, are being ignored.
As long as budget projections remain systematically wrong and attempts are made to govern through tax patches and fiscal surprises, certainty —that invisible public good, yet indispensable for the economy to breathe— will remain absent.
Without credibility in macroeconomic rules, no Budget Review can conceal a course that has gone astray.
And worse still, when the miscalculated deficit is acknowledged and spending is still increased instead of priorities being ordered according to the general public interest, rather than political interest.
