Numerical evaluation of the critical price and American options

An approximate solution to the American put value is proposed and implemented numerically. Relaxation techniques enable the critical price to be determined with high accuracy. The method uses a modification of the quadratic approximation of MacMillan and Barone-Adesi and Whaley which gives an expression for the critical price. Numerical experimentation and iterative methods quickly provide highly accurate solutions.     

The Swedish State unemployment insurance and the reinsurance problem of the funds

Abstract

In 1901 the town of Gent appropriated a municipal grant to societies paying benefit to their members in case of unemployment. The decision was founded on a committee report principally written by the lawyer Louis Varlez. The societies should claim individual contributions of the members constituting the right to unemployment allowance under certain conditions. In order to prevent a dissipating risk selection the sphere of activity of a society should join with some society existing before. Such societies had been erected at several places as well in Belgium as in other states, in Gent as early as in 1867. In most cases they were attached to trade unions. It may thus be said that a subsidized unemployment insurance was — for the first time — introduced in Gent 1901. The principles applied are usually called the »Gentsystem». In general accordance with this system state subsidized unemployment insurance was introduced in France 1905, in Norway 1906 and in Denmark 1907. Later several states have established unemployment insurance on a voluntary basis. In modern voluntary state insurance, however, a decisivestress is laid upon the fact that the allowance shall be regulated in accordance with the general rules for public relief of unemployment. Some conditions of the insurance scheme are thus compulsorily laid down in the regulations concerning the subsidy. In some states the unemployment insurance has been wholly established on a compulsory basis. For the first time a compulsory insurance was introduced in England in 1911 covering certain occupational groups. Compulsory unemployment insurance has then been erected in Italy 1919, Poland 1924, Bulgaria 1925 and Norway 1938. In 1938 a law bearing on a change of the voluntary unemployment insurance of Belgium to a compulsory one is being prepared.     

How the German government responded to the financial,economic and fiscal crises

This paper explains the German government's response to the financial, economic and fiscal crises. It covers the financial crisis in 2008 when banks were supported (SoFFin), the economic crisis in 2009, and the fiscal crisis of increasing state debts and budget deficits which caused the German government to cut spending (Sparpaket) in 2010. The author looks at the contents of the government's responses, but also at the political and administrative aspects of the government's decision-making processes.     

A UK Empirical Test of the Larson-Gonedes Exchange Ratio Model

This paper adopts the Larson-Gonedes merger exchange ratio determination model to investigate the bargaining area in UK takeovers involving share-for-share exchanges. The model focuses on price-earnings ratios rather than share price returns and so is more consistent with practical valuation methods than other approaches. The basic model is extended for the UK to consider both cash alternative offers and mixed offers involving cash and equity consideration. The model is tested on a sample of 95 UK takeovers between 1984 and 1988 using consecutively unadjusted, FT All Share Index adjusted and beta adjusted price bases. The analysis adopts the conventional chi-square test used by Conn and Nielsen but, in addition, a new test is developed based on a Generalised Likelihood Ratio. We find that on an unadjusted price basis there is greater support for the Larson-Gonedes model in the UK than Conn and Nielsen found for the US. However, our extended model based on adjusted prices provides more cautious support. In addition, we conduct a sensitivity analysis to test the robustness of the results and provide further evidence on the wealth effects on acquiring and acquired company shareholders.     

Testing a Model of Cognitive Budgetary Participation Processes in a Latent Variable Structural Equations Framework

Previous accounting research has suggested that subordinate participation in the budgetary process has two cognitive aspects: (1) participation enhances budget quality, and hence the utility of budgets, by allowing subordinates to introduce private knowledge into the budgetary process, and (2) participation enables subordinates to obtain information that is relevant to performing their jobs. This study tests a model that encompasses both cognitive aspects of budgetary participation. Data were gathered with a questionnaire distributed to managers from a variety of different national origins who were working in many different global locations. The data were analysed with latent variable structural equation modelling, which provides several advantages over more conventional analytic methods generally used in budgetary participation and other behavioural accounting research. The results indicated that participation enhances budget quality and that budget quality, in turn, has a positive effect on budget utility. Participation was also found to have a direct and positive effect on job-relevant information. The results failed to support a proposed indirect effect of participation on job-relevant information through the enhancement of budget quality.     

Small firms and the value of improvements in corporate governance mechanisms

Since 2002, many firms have been required to alter their board of directors and committees to increase management monitoring. Kinney and McDaniel (1989) and Chhaochharia and Grinstein (2007) provide empirical evidence suggesting that investments in corporate governance may differ based on firm size, and that under-investing in monitoring may be more pronounced in smaller firms. To further test whether the benefits of recent changes in companies' governance mechanisms accrue to smaller firms that have underinvested in governance, we examine the stock market reaction to changes in board structure over the twenty-four months following the passage of the Sarbanes–Oxley Act. We construct a new composite measure of board structure and regress buy-and-hold abnormal returns on changes that occur in the Board Structure Index, finding that improvements in corporate governance quality result in economically significant abnormal returns accruing only to the smaller firms with weak initial board structures.     

Words versus Actions about Organ Donation: A Four-Year Tracking Study of Attitudes and Self-Reported Behavior

Historically, the proportion of the American public that expresses positive views about organ donation exceeds the proportion that actually signs an organ donor card (ODC). The public seems to say one thing but does another. In July 1994, The Advertising Council, Inc., in conjunction with the Coalition on Donation, launched a major promotional campaign to educate the U.S. public about organ and tissue donation. This article reports on a four-year study tracking attitude toward organ donation and transplantation and its relationship with direct experience (knowing an organ recipient) and intermediate behaviors. The intermediate behaviors investigated are donating blood and signing an ODC. No significant changes were noted in attitude toward donation, but the proportion of individuals who had signed an ODC increased significantly.     

Reinforcement-Based Adaptive Learning in Asymmetric Two-Person Bargaining with Incomplete Information

The sealed bidk-double auction is a mechanism used to structure bilateral bargaining under two-sided incomplete information. This mechanism is tested in two experiments in which subjects are asked to bargain repeatedly for 50 rounds with the same partner under conditions of information disparity favoring either the buyer (Condition BA) or seller (Condition SA). Qualitatively, the observed bid and offer functions are in agreement with the Bayesian linear equilibrium solution (LES) constructed by Chatterjee and Samuelson (1983). A trader favored by the information disparity, whether buyer or seller, receives a larger share of the realized gain from trade than the other trader. Comparison with previous results reported by Daniel, Seale, and Rapoport (1998), who used randomly matched rather than fixed pairs, shows that when reputation effects are present this advantage is significantly enhanced. A reinforcement-based learning model captures the major features of the offer and bid functions, accounting for most of the variability in the round-to-round individual decisions.
