A small open economy is experiencing a negative supply shock due to rising global oil prices. The short-run aggregate supply (AS) curve is defined as: $$ \pi_t = \pi_e + \lambda (Y_t - Y^P) + \gamma \Delta P_{oil} $$ Where, $\pi_t$= current inflation rate; $\pi_e$= expected inflation; $Y_t$= Actual output; $Y^P$= Potential Output; $\lambda$ = output gap sensitivity (0.3); $\gamma$ = oil price sensitivity (0.4); $\Delta P_{oil}$= percentage change in global oil prices. Assume the central bank is targeting an inflation rate of 3%. (a) Current Inflation: Oil prices increase by 20%, expected inflation is 4%, and actual output is 5% below potential. Calculate the current inflation rate. (b) Output Adjustment: The central bank implements a contractionary policy to bring inflation back to the 3% target. Determine the output adjustment needed to achieve this target if $\Delta P_{oil}$ remains constant and $\pi_e$ stays at 4%. (c) Credibility Dynamics: If the public perceives the central bank to be ineffective and expected inflation rises to 6%, recalculate the inflation rate assuming output remains at its adjusted level. Discuss the implications for the central bank's credibility and suggest a mathematical strategy for minimizing welfare loss, given: $$ L = (\pi_t - \pi^*)^2 + \beta (Y_t - Y^P)^2; $$ where $\beta = 0.8$
