Talk about Allowance for Corporate Equity
De Mooji and Deveurex (2010):
Talk about CBIT
- not neutral tax as taking return to capital so alter NPV
Tax on economic rent impact i) investment decisions?
ii) Location decisions?
i) No - doesn’t impact WACC so doesn’t impact NPV
ii) Yes - if mobile activity
Why FFC helpful?
Fama and French (2012) reject CAPM and 3 factor model in their tests of global CAPM
Equity premium puzzle - evidence US luck
Siegel’s (2002) data from roughly 1900 to 2000, all countries from the UK (6.1%) to Japan (9.3%) to India (11.3%) have equity premiums - not solely US luck.
Explanations equity premium puzzle: mismeasurement of consumption
Savoy (2011): measure garbage - more volatility that GDP consumption methods.
- coefficient on risk aversion from 81 to 17
Mehra and Prescott (2003):
- credit constraints, young shut out market, priced by select group with different marginal rate of substitution of consumption
Solutions to excess volatility puzzle
Price-to-price feedback theory (Shiller 2003):
Smart money - need to offset for theoretical models to have relevance in stock market
Permanent vs transitory: if assume p dividend cut they over estimate as sceptical - info asymmetries.
Explain trade-off theory
Explain pecking order theory
Myers and Majiluf (1984):
Evidence for trade / pecking order
Weakness of pecking order theory.
Forgo profit maximising behaviour: not max shareholder value
Testing empirically TO and PO
Rajan and Zingales (1995):
Between countries vs within : different tax levels
- issues over investor protection
Age and debt:
- negative relationship rejects prediction of TOT but accords with PO
CEOs
CAPM assumptions
1) mean-variance preferences
2) homogenous investors
3) no transaction costs
4) lending/borrowing at risk-free rate
Problems in testing CAPM
Roll (1977) critique: what is the market portfolio - use proxies.
- Jagganathan and Wang (1993): add human capital in market portfolio using n as proxy, more cross-sectional variance explained
Finding beta:
Expectations - ex ante
Joint hypothesis testing problem: bad pricing or bad asset pricing model?
Evidence against CAPM
Alpha = 0 if on SML (graphical depiction of CAPM) - Jensen’s alpha: find s.d. alpha large and not zero, not a blip that is arbitraged away, persist.
BJS (1972): find SML flatter. No risk-free rate or using proxies?
Other factors have explanatory power beyond beta:
What is FF and FFC models
Argue from ICAPM to motivate using other factors but don’t say why those factors. Multiple time periods: multiple beta coefficients.
FF 93:
- 3 factor: market risk, SMB,HML
FFC 97: add in momentum
- PR1YR: winners - losers
FFC claim explain 90% of portfolio returns whilst CAPM 70%
What is APT
Arbitrage pricing theory
What is equity premium puzzle
Mehra and Prescott (1985):
Explanations for equity premium puzzle (in short)
Explain rare disaster
Barrow (2006): investors rationally worried about small chance of eco catastrophe.
Siegel and Thaler (1997): most financial holocausts that destroy stock value, have hyperinflation or govt appropriating most real value of debt so worse off in bonds.
Explain loss aversion
Kahneman and Tversky (1979): prospect theory where more sensitive to losses than gains of same magnitude.
MM proposition and assumptions
MM with tax
Modigliani-Miller (1958): firm value is independent of market structure. If not then an arbitrage opportunity would exist where investors could ‘home make’ the firm’s leverage - financial innovation would extinguish any deviation from predicted income.
- value depends on future cash flows not how split these up for providers of capital
Assumptions: costless default, perfect capital markets, homogenous expectations, no tax, cash-flows independent of cap structure
With tax: lower WACC
Indirect costs of default
Debt overhang (Myers 1977): pass-up on +ve NPV projects as
Excess volatility puzzle explanation
Shiller (1990): stock prices more volatile than NPV of dividends
