Do financial distress and liquidity crises affect value and size premiums?

This study investigates the impact of liquidity crises on the relationship between stock (value and size) premiums and default risk in the US market. It first examines whether financial distress can explain value and size premiums, and then, subsequently, aims to determine whether liquidity crises increase the risk of value and size premium investment strategies. The study employs a time-varying approach and a sample of US stock returns for the period between January 1982 and March 2011, a period which includes the current liquidity crisis, so as to examine the relationship between default risk, liquidity crises and value and size premiums. The findings indicate that the default premium has explanatory power for value and size premiums, which affect firms with different characteristics. We also find that liquidity crises may actually increase the risks related to size and value premium strategies.     

Richardson extrapolation techniques for the pricing of American‐style options

In this article, the authors reexamine the American‐style option pricing formula of R. Geske and H.E. Johnson (1984), and extend the analysis by deriving a modified formula that can overcome the possibility of nonuniform convergence (which is likely to occur for nonstandard American options whose exercise boundary is discontinuous) encountered in the original Geske–Johnson methodology. Furthermore, they propose a numerical method, the Repeated‐Richardson extrapolation, which allows the estimation of the interval of true option values and the determination of the number of options needed for an approximation to achieve a given desired accuracy. Using simulation results, our modified Geske–Johnson formula is shown to be more accurate than the original Geske–Johnson formula for pricing American options, especially for nonstandard American options. This study also illustrates that the Repeated‐Richardson extrapolation approach can estimate the interval of true American option values extremely well. Finally, the authors investigate the possibility of combining the binomial Black–Scholes method proposed by M. Broadie and J.B. Detemple (1996) with the Repeated‐Richardson extrapolation technique. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:791–817, 2007     

Independent Financial Advisers – Why They Remain the Strongest Distribution Route for Pensions

Despite financial services companies operating in multiple channels, the Independent Financial Advisers (IFAs) channel remains the most popular distribution route when it comes to pension sales. To understand how they compete and the nature of the strategic groups within this channel, this paper examines how IFAs perceive they add value to the decision making of consumers when purchasing pension products. The paper identifies four strategic groups of the IFA population (operating within the pensions market) based on the benefits they perceive they can add to their service to assist consumer decision making. Using cluster analysis within SPSS from a survey of 468 IFAs, four main groups emerge; these can be classified in terms of (1) analytical skills, (2) value for money, (3) reputation and (4) personalised service.     

On Adaptive Emergence of Trust Behavior in the Game of Stag Hunt

We study the emergence of trust behavior at both the individual and the population levels. At the individual level, in contrast to prior research that views trust as fixed traits, we model the emergence of trust or cooperation as a result of trial and error learning by a computer algorithm borrowed from the field of artificial intelligence (Watkins 1989). We show that trust can indeed arise as a result of trial and error learning. Emergence of trust at the population level is modeled by a grid-world consisting of cells of individual agents, a technique known as spatialization in evolutionary game theory. We show that, under a wide range of assumptions, trusting individuals tend to take over the population and trust becomes a systematic property. At both individual and population levels, therefore, we argue that trust behaviors will often emerge as a result of learning.     

The normal distribution as a model of technological substitution

A model for forecasting technological substitution, based on the use of the normal distribution, is presented. Both mathematical and graphical techniques are discussed. Examples from the literature are used to illustrate the model.     

The Determinants of Implied Volatility: A Test Using LIFFE Option Prices

This paper presents and tests a model of the volatility of individual companies' stocks, using implied volatilities derived from option prices. The data comes from traded options quoted on the London International Financial Futures Exchange. The model relates equity volatilities to corporate earnings announcements, interest-rate volatility and to four determining variables representing leverage, the degree of fixed-rate debt, asset duration and cash flow inflation indexation. The model predicts that equity volatility is positively related to duration and leverage and negatively related to the degree of inflation indexation and the proportion of fixed-rate debt in the capital structure. Empirical results suggest that duration, the proportion of fixed-rate debt, and leverage are significantly related to implied volatility. Regressions using all four determining variables explain approximately 30% of the cross-sectional variation in volatility. Time series tests confirm an expected drop in volatility shortly after the earnings announcement and in most cases a positive relationship between the volatility of the stock and the volatility of interest rates.     

Did political constraints bind during transition?Evidence from Czech elections, 1990–20021

Many theoretical models of transition are driven by the assumption that economic decision making is subject to political constraints. In this paper we test whether the ‘winners’ and ‘losers’ of economic reform influenced voting behaviour in the first five national elections in the Czech Republic. We propose that voters, taking stock of endowments from the planning era, could predict whether they would become winners or losers of transition. Using survey data we measure the degree to which regions were ‘not afraid’ or ‘afraid’ of economic reform in 1990. We define the former as potential ‘winners’ who should vote for pro‐reform parties and the latter as potential ‘losers’ who should support left‐wing parties. Using election results and economic indicators at the regional level, we demonstrate that there is persistence in support for pro‐reform and communist parties which is driven by prospective voting based on initial conditions in 1990. We find that regional unemployment rates in 2002 are good predictors of voting patterns in 1990 and provide empirical evidence that political constraints bind during transition.     

Institutional determinants of Indonesia's sugar trade policy

An analysis of contemporary sugar trade policy in Indonesia highlights problems in the institutional framework for trade policy making. The institutions through which sugar trade policy is formulated entrench the interests of rent-seeking bureaucrats, import licence holders and traders to the detriment of consumers and downstream producers of processed products. Moreover, the resulting trade policy regime has problematic effects on sugarcane farmers. The structure of regulatory intervention is due less to democratic pressures than to the inclusion of vested interests in the institutions that formulate policy. Further, the lack of effective mechanisms for inter-ministerial coordination and for resolving conflicting policy preferences among ministries hinders the development of coherent trade policy and obstructs reform efforts. An institutional framework that facilitates representation of all interests affected by sugar trade policies and public scrutiny of the effects of policy intervention is likely to deliver better outcomes for consumers and producers alike.
