Investment Strategy, Mathematical Finance & Macroeconomic Theory

I work at the intersection of investment strategy, applied investment research and consultant, general equilibrium asset pricing, and fiscal-monetary theory. My work spans quantitative modelling, factor investing, inflation dynamics and price level determination, optimal IPO timing, liability-driven investing for central banks and individuals, and quantitative tools that bring rigorous economic models into practice.

About me

I am a mathematical engineer working at the intersection of investment strategy, wealth management solutions, general equilibrium theory, macroeconomic policy, and applied investment research. My research addresses foundational questions in asset pricing and monetary economics — including how markets endogenously complete through IPO activity, and how the price level is determined as a market-clearing condition between fiscal obligations and aggregate consumption claims.

On the institutional side, I have worked on strategic asset allocation and ALM frameworks for central bank reserves and sovereign wealth funds, applying risk factor decomposition and dynamic portfolio insurance to real-world constraints. On the applied side, I build quantitative tools for portfolio optimization, asset allocation, and personal financial planning.

I believe the best financial research is not only mathematically honest but genuinely useful — ideas that can be translated into better policy, better portfolios, or clearer thinking about risk, value, and monetary stability.

Nominal Representation and Price Level Determination
Mauro Villalón
We derive the price level as the unique denomination rate making a nominal system an admissible representation of the real economy. A denomination system — an exogenous, fungible stock of nominal units — induces a pricing functional over the same accessible flows as the stochastic discount factor. Admissibility requires these two functionals to share the same null sets on the accessible Hilbert subspace; in a Hilbert space, this forces exact functional equality. Dynamic extension via the Doob--Meyer decomposition yields a flow condition on the SDF-scaled denomination stock; integration under a no-bubble condition produces the valuation identity equating the real value of the stock to the present value of accessible consumption. Existence and uniqueness follow under completeness and transversality, without friction, liquidity preferences, or a government budget constraint. Applied to a fiat economy, the framework delivers a generalized Fisher relation and a three-channel decomposition of inflation.

The Price Level in a General Equilibrium Valuation Framework
Mauro Villalón
Proposes a valuation framework that endogenizes the price level as the market-clearing variable between the settlement base and claims on aggregate consumption. Using a continuous-time setting, the paper characterizes the joint dynamics of inflation, output, and fiscal risk — formally distinguishing expected inflation (anchored by the nominal rate) from unexpected inflation arising from real, valuation, and fiscal shocks. A structural fiscal monetization capacity integrates Ricardian and Non-Ricardian regimes, delivering closed-form solutions for asset prices and inflation volatility. As an application, the framework differentiates the transmission of balance sheet operations: zero-net-supply operations are monetarily neutral, whereas valuation shocks — such as pension fund liquidations — may generate inflationary adjustments by steepening the economy's stochastic discount factor.

Working Paper
Endogenous Market Completion & the Public Listing of Large Private Sectors
with J. Casassus & D. Villalón
Develops a general equilibrium model in which private sector choose optimally when to go public, endogenously completing financial markets. The model links IPO timing to aggregate risk, market incompleteness, and investor welfare, generating novel predictions about listing cycles and the cost of capital.

Working Paper
Asset Liability Management Investment Strategy for International Reserves: A Risk Factors and Contingent Capital Preservation Approach
with N. Goldberger — Central Bank of Chile
Proposes a methodology for optimal asset allocation of the international reserves of the Central Bank of Chile. The approach optimizes exposures at the level of global systematic risk factors — reducing dimensionality and improving economic interpretability — and introduces a structural rebalancing rule that replicates a protective put option, ensuring contingent capital preservation and liquidity for the reserves portfolio.
