Reflections on Macroeconomic Analysis

My interest in macroeconomics predates my time at the International Monetary Fund (IMF). It partly stems from a personal experience of hyperinflation in Zimbabwe as well a desire to understand global economic and financial developments in a coherent model. My graduate thesis is a study of the risks associated with euro bond issuance by commodity-dependent sub-Saharan African countries. The relevant framework for this is the Debt Sustainability Analysis (DSA), which I summarize below. Written under the supervision of Professor Jeffrey Frankel–a preeminent macroeconomist who served in President Clinton's Council of Economic Advisers–my thesis recommends issuance of commodity bonds as a mitigant to unsustainable debt. I have already blogged about my findings elsewhere, so I would like to use this post to reflect on some of the macro theories and models that I have learned. Here is an outline derived from one of my favorite courses at the Kennedy School–API-120: Advanced Open Economy Macroeconomics taught by Jeff Frankel in the Fall of 2012.
  1. Devaluation and the Trade Balance
    1. Marshall-Lerner
  2. Mundell-Fleming Model
    • Keynesian trade balance
    • Monetary and Fiscal Policy
      • Under a fixed exchange rate regime; 
      • Under a floating regime and Capital Mobility
  3. Money and Inflation
    • Aggregate supply
    • Monetary Policy
      • Dynamic Inconsistency and Rules
    • Seignorage and Hyperinflation
  4. Purchasing Power Parity
    • Does PPP hold
    • Why does PPP fail?
      • Sticky prices
      • Trade barriers
      • Non-traded goods
  5. Small Open Economies
    • Devaulation in SOEs
    • The Salter-Swan ("Nontraded goods") Model
    • Dutch Disease
  6. Exchange Rate Regimes
    • Classification, pros and cons
    • Optimum Currency Area
  7. Integration of Financial Markets
    • Intertemporal trade theory & capital mobility
    • Procyclicality 
    • Interest rate parity (covered, uncovered, real)
  8. Exchange Rate Determination
    • Flexible price models
    • Bubbles
    • Sticky-price models and overshooting
  9. Crises in Emerging Markets
    • Speculative attack models
    • Boom-bust cycle; Early warning indicators; Sudden stops; Contagion
  10. Forward Market Bias & Portfolio Diversification
    • Exchange rate forecasting and forward bias ("carry trade")
    • Optimal portfolio diversification
    • Home bias
    • Country risk and Debt Sustainability Analysis
To be continued...

Unemployment by state in the USA

Below is a visualization of unemployment rates by county using a powerful Python library called Bokeh . The two maps are for the states of Texas and the Commonwealth of Massachusetts. As the second largest economy in the United States (10th largest in the world), Texas shows interesting county variation in macroeconomic factors such as unemployment. According to Wikipedia , in 2015, Texas was home to six of the top 50 companies on the Fortune 500 list and 51 overall (third most after New York and California). The northern counties were least affected by the financial crisis of 2008/09. Dallas–Fort Worth–Arlington area encompasses 13 counties which constitute the economic and cultural hub of the region commonly called North Texas or North Central Texas. Bokeh Plot The least affected counties in Massachusetts were the southernmost tourist areas of Nantuckett and Dukes County. The ...

Modeling Core PCE inflation: A dual approach

Today's release of the August 2025 Personal Consumption Expenditures (PCE) inflation data drew widespread media attention, with coverage highlighting both the persistence of inflation and its implications for Federal Reserve policy. Across outlets, analysts pointed to resilient consumer spending and income growth as signs of underlying economic strength, even as inflation remains above the Fed's 2% target. The consensus among media reports is that while inflation is not worsening, its stubbornness continues to challenge policymakers navigating a softening labor market and evolving rate expectations. To provide deeper insights into inflation's trajectory, I've developed a forecasting framework that combines two econometric approaches — ARIMA time series modeling and Phillips Curve analysis—to predict Core PCE inflation. This analysis presents a unique opportunity to validate my forecasting methodology against eight months of 2025 data. ...

Malaysia at a Cross Roads: Diagnosing the Constraints to High Income Status

Malaysia at a Crossroads: Diagnosing Constraints to High-Income Status In 2008, Malaysia was recognized by the Growth Commission – a distinguished panel comprising 2 Nobel Prize Winning Economists and other leading development practitioners – as one of thirteen countries that sustained high growth in the post-war period. The 30-year stretch that caught the attention of the Growth Commission was between 1967 and 1997 when Malaysia grew at an average of 7.3% per year. This long stretch of growth was interrupted by periods of external shocks including the Volcker shock of 1986, the Asian Financial crisis in 1997/8, later the so-called Dot Com Bubble of 2001, and more recently the Global Financial Crisis of 2008. Despite these shocks, Malaysia remained resilient - formally earning the title "Upper Middle Income Country" in 1992. (See summary figure that breaks down the country's per capita growth story). As...
