Capital Gains Taxation and Asset Pricing Dynamics

Capital gains taxation exerts a profound influence on the valuation, trading behaviour and liquidity of financial assets. By altering the after-tax return landscape, tax regimes shape investor preferences and portfolio allocation, prompting dynamic adjustments in equilibrium prices. Economists have shown that higher effective tax rates can induce a lock-in effect, whereby holders defer realisation of gains to minimise tax liabilities, thereby reducing market turnover and potentially depressing asset valuations. Conversely, preferential treatment or tax deferral mechanisms can stimulate trading activity and capital reallocation across asset classes, enhancing market efficiency. Theoretical advances now integrate taxation directly into asset pricing models, embedding heterogeneous investor horizons, liquidity constraints and behavioural considerations. Empirical work spans diverse jurisdictions—from comprehensive examinations of real-estate tax deferral strategies to analyses of equity holding periods under flat-rate withholding taxes—revealing consistent patterns in how fiscal policy drives risk-adjusted returns and market dynamics. This body of research underscores the global relevance of capital gains taxation, influencing policy debates on revenue generation, economic growth and financial stability. Practical applications range from the design of investor-friendly tax incentives to the calibration of macroprudential measures that account for tax-induced distortions in asset markets.
