Question 1

Since 1 January 2025 Brazil has operated a continuous inflation target (meta contínua) instituted by Decreto nº 12.079/2024, with the target fixed by the National Monetary Council (CMN) in Resolução CMN nº 5.141/2024. Under this framework, when is the inflation target formally considered to have been missed, and what must Banco Central do Brasil then do?

The 12-month accumulated IPCA is compared with the target and its tolerance interval every month; the target is only considered missed once inflation has stayed outside the tolerance interval for six consecutive months, at which point the Governor must send an open letter (carta aberta) to the Minister of Fazenda and publish a note in the Relatório de Política Monetária. The target is verified only in December of each calendar year, and a single month of 12-month IPCA above the ceiling in December is enough to characterise a breach. Compliance is measured on core inflation (núcleo do IPCA) held strictly at the midpoint of the target, with no tolerance interval permitted. The Federal Senate evaluates whether the IGP-DI stays within a fixed ±3.0 percentage point band and applies a sanction to Banco Central do Brasil if it does not.

Correct Answer:

Question 2

In a standard Mundell-Fleming open-economy model with perfect capital mobility and a flexible exchange rate regime, what is the effect of an expansionary fiscal policy (an increase in government spending)?

It generates a complete crowding-out effect through currency appreciation, leaving aggregate output (Y) unchanged while worsening net exports (NX). It permanently increases aggregate output because lower domestic interest rates induce capital inflows and currency depreciation. It raises domestic interest rates permanently above international rates without affecting the nominal or real exchange rate. It shifts the LM curve to the right, causing a simultaneous increase in output and private investment.

Correct Answer:

It generates a complete crowding-out effect through currency appreciation, leaving aggregate output (Y) unchanged while worsening net exports (NX).

Question 3

Consider a small open economy operating under a fixed exchange rate regime and perfect capital mobility. Which policy is fully effective at changing national income (output), and why?

Fiscal policy is fully effective because the central bank must expand the domestic money supply to maintain the fixed exchange rate peg against appreciation pressure. Monetary policy is fully effective because autonomous open market purchases permanently lower domestic interest rates without altering foreign reserves. Trade tariffs are fully effective because they eliminate capital mobility and isolate the central bank from foreign exchange interventions. Neither fiscal nor monetary policy can affect output due to the absolute validity of the Ricardian Equivalence proposition.

Correct Answer:

Fiscal policy is fully effective because the central bank must expand the domestic money supply to maintain the fixed exchange rate peg against appreciation pressure.

Question 4

According to the classic Taylor Rule specification for central bank policy rates, what does the 'Taylor Principle' mandate to ensure macroeconomic stability and anchor inflation expectations?

The monetary authority must increase the nominal policy interest rate by more than one-for-one (coefficient greater than 1) in response to an increase in inflation, thereby raising the real interest rate. The central bank must keep the nominal policy interest rate strictly constant while letting commercial bank reserve requirements adjust to inflation differentials. The nominal interest rate must adjust exactly one-for-one with expected inflation to maintain a zero real interest rate at all times. The central bank should reduce the nominal interest rate when inflation rises in order to lower the financing costs of domestic firms.

Correct Answer:

Question 5

In the macroeconomic literature on fiscal dominance (e.g., Sargent and Wallace's 'Some Unpleasant Monetarist Arithmetic'), what occurs when a central bank attempts to tighten monetary policy in an economy with an unsustainable fiscal path and non-Ricardian regime?

Higher real interest rates increase debt servicing costs, accelerating public debt accumulation and forcing higher future monetary expansion or risk premia, which leads to currency depreciation and higher inflation. Higher interest rates immediately generate large fiscal surpluses, restoring debt sustainability and eliminating inflation instantly. The central bank achieves immediate price stability with zero impact on sovereign bond yields or fiscal accounts. The money multiplier contracts to zero, permanently severing the connection between central bank liquidity and the banking system.
