Persistence and the four‐factor model in the Australian funds market: a note

We investigate whether Australian fund managers are able to deliver persistent performance using Carhart’s (1997) four‐factor model. Short‐ and long‐term persistence is examined and the sample is also divided into unit trusts and superannuation funds. We do not find evidence of persistence in any sample of funds. We find that winner (loser) funds tend to hold past winner (loser) stocks. Winner and loser unit trusts both appear to have positive exposure to small stocks.     

Real option pricing with mean-reverting investment and project value

In this work, we are concerned with valuing the option to invest in a project when the project value and the investment cost are both mean-reverting. Previous works on stochastic project and investment cost concentrate on geometric Brownian motions (GBMs) for driving the factors. However, when the project involved is linked to commodities, mean-reverting assumptions are more meaningful. Here, we introduce a model and prove that the optimal exercise strategy is not a function of the ratio of the project value to the investment V/I – contrary to the GBM case. We also demonstrate that the limiting trigger curve as maturity approaches traces out a nonlinear curve in (V, I) space and derive its explicit form. Finally, we numerically investigate the finite-horizon problem, using the Fourier space time-stepping algorithm of Jaimungal and Surkov [2009. Lev´y based cross-commodity models and derivative valuation. SIAM Journal of Financial Mathematics, to appear. http://www.ssrn.com/abstract=972837]. Numerically, the optimal exercise policies are found to be approximately linear in V/I; however, contrary to the GBM case they are not described by a curve of the form V*/I*=c(t). The option price behavior as well as the trigger curve behavior nicely generalize earlier one-factor model results.

Intrinsic inflation persistence

Empirical evidence suggests that inflation determination is not purely forward-looking, but models of price setting have struggled to rationalize this finding without directly assuming backward-looking pricing rules for firms. This paper shows that intrinsic inflation persistence can be explained with no deviation from optimizing, forward-looking behaviour if prices that have remained fixed for longer are more likely to be changed than those set recently. A relationship between the probability of price adjustment and the duration of a price spell is shown to imply a simple “hybrid” Phillips curve including lagged and expected inflation, which is estimated using macroeconomic data.     

“Skewness and Stock Option Prices”, Hans Gerber and Bruno Landry,July 1997

We determine the optimal amount of life insurance for a household of two wage earners. We consider the simple case of exponential utility, thereby removing wealth as a factor in buying life insurance, while retaining the relationship among life insurance, income, and the probability of dying and thus losing that income. For insurance purchased via a single premium or premium payable continuously, we explicitly determine the optimal death benefit. We show that if the premium is determined to target a specific probability of loss per policy, then the rates of consumption are identical under single premium or continuously payable premium. Thus, not only is equivalence of consumption achieved for the households under the two premium schemes, it is also obtained for the insurance company in the sense of equivalence of loss probabilities.     

Does reduced trade tax revenue affect government spending patterns?

Many skeptics of trade liberalization in the developing world argue that lowering trade taxes can cause significant fiscal pressures in countries particularly reliant on these taxes and result in a reallocation of resources away from important development goals. This paper evaluates whether there is evidence that central governments systematically change the composition of spending priorities in the wake of lowered trade tax revenues as a share of total government revenues. We find no systematic evidence for this concern in a sample of 51 developing countries for the 1991 through 2005 period.     

The incremental information content of non-US GAAP earnings disclosures: Evidence from UK firms

This paper examines price and trading volume responses in the US equity market to the preliminary earnings announcements (PEAs) in the UK of UK firms listed on US exchanges (e.g., NYSE and AMEX). The inquiry focuses on whether the return forecast error (absolute and squared values) and volume residual (standardized and unstandardized) for each day were significantly different from the average on the day of the earnings announcements (PEA). The most significantly unexpected return occurred the day prior to the Financial Times (FT) announcement. The results suggest prompt volume and price responses to the UK PEAs in the US security market. Excess trading volume occurred the day prior to and the day of the FT release price response occurred on the day subsequent to the PEAs. This may suggests that investors possess differential prior beliefs or likelihood functions in evaluating public disclosure. Consistent with Frost and Pownall [Frost, C., & Pownall, G. (1996), Interdependencies in the global markets for capital and information: The case of Smithkline Beecham plc. Accounting Horizons, 1, 38-57], US investors seem not to be confused by US/UK generally accepted accounting principles (GAAP) differences, and in fact use information about UK GAAP earnings in their valuations and trading decisions. This implies that traders correctly use UK accounting output to the determination of values in setting security prices and arriving at trading decisions. Broadly, these findings support the assumption that disclosures by UK-listed firms in their domestic market influence share liquidity and trading in the US market.     

Intraday jumps and US macroeconomic news announcements

This paper applies recent non-parametric intraday jump detection procedures to investigate the presence and importance of intraday jumps in US futures markets. More importantly, the paper investigates the extent to which statistically significant intraday jumps are associated with US macroeconomic news announcements. Jumps are prevalent, large and contribute heavily to total daily price variation. Approximately one third of jumps correspond to US macroeconomic news announcements, with pure announcement effects causing large increases in the absolute sizes of jumps and the informational surprise of the announcement explaining large proportions of the jumps. The statistical and economic significance of news-related jumps is confirmed by results that show higher volatility persistence, predictability of lower frequency returns, larger effects on microstructure variables, jump clustering and co-jumps from these jumps versus non-news-related jumps, although there are some interesting variations across asset classes.
