A noncooperative model of contest network formation

In this paper we study a model of weighted network formation. The bilateral interaction is modeled as a Tullock contest game with the possibility of a draw. We describe stable networks under different concepts of stability. We show that a Nash stable network is either the empty network or the complete network. The complete network is not immune to bilateral deviations. When we allow for limited farsightedness, a stable network immune to bilateral deviations must be a complete $M$-partite network, with partitions of different sizes. We provide several comparative statics results illustrating the importance of the structure of stable networks in mediating the effects of shocks and interventions. In particular, we show that an increase in the likelihood of a draw has a nonmonotonic effect on the level of wasteful contest spending in the society. To the best of our knowledge, this paper is the first attempt to model weighted network formation when the actions of individuals are neither strategic complements nor strategic substitutes.     

A study of the effect of age and gender upon student business ethics

The present survey was voluntarily and anonymously completed by 2,196 students enrolled in business courses at the University of Southern Mississippi. The intent of the survey was to determine whether or not age or gender played a role in a person's perception of proper ethical conduct.The findings suggests that gender is a significant factor in the determination of ethical conduct and that females are more ethical than males in their perception of business ethical situations.Students were divided into groups according to age as follows: under 21 years, 22–30 years, 31–40 years, and 40 plus years. The results of this survey also suggest that age is a determining factor in making ethical decisions. The statistics suggest that those students falling in the 40 plus years age group were the most ethical, followed in order by the 31–40 group, the 22–30 group and those of 21 years of age and under.Durwood Ruegger is currently an Associate Professor of Finance and General Business at the University of Southern Mississippi.

Financial Challenges Facing Urban SMEs under Financial Sector Liberalization in Ghana

The paper examines the impact of financial sector liberalization (FSL) policies on the financial management of small and medium-sized enterprises (SME) in Ghana, using six case studies. Its findings, which confirm and extend the conclusions of previous studies, are integrated into a framework that explains the impact of FSL and the factors at work. The main financial challenge facing SMEs is access to affordable credit over a reasonable period. This is determined by the financing needs of SMEs and the action of investors. SME financing needs reflect their operational requirements, while the action of investors depends on their risk perception and the attractiveness of alternative investment (which affects their willingness to invest). Government borrowing, the general economic climate, availability of collateral, quality of SME record keeping, and SME investor relations skills affect the way in which this challenge is managed. The impact of the activities and potential of enterprise development agencies are also discussed.     

Comparing classification accuracy of neural networks,binary logit regression and discriminant analysis for insolvency prediction of life insurers

Past studies have documented the failure of the Insurance Regulatory Information System (IRIS) to provide adequate warning of insurer financial distress or insolvency. As a result, scholars have examined alternative parametric and non-parametric models to predict insurer insolvency. This study uses a neural network, a non-parametric alternative to past techniques, and shows how this methodology predicts insurer insolvency more effectively than parametric models.     

The Austrian theory of the cooperative firm

This paper draws on Wicksell's Value, Capital and Rent. The (comparative-statics) response of the cooperative to a change in its parameters (capital stock, rate of interest paid on capital stock, and production function) is examined. Severe employment problems may be expected if, in a cooperative setting, the rate of interest is, by macroeconomic management, kept at a relatively low level. Technological progress also may lead to a contraction in employment and even, under some circumstances, cause a decline in output per man. The cooperative is throughout contrasted with its capitalist counterpart.     

Financial Market Fragmentation and Reforms in Ghana, Malawi, Nigeria, and Tanzania

This article reports the findings from surveys of formal andinformal institutions and their clients in Ghana, Malawi, Nigeria,and Tanzania. It investigates the hypothesis that reformingfinancially repressive policies would not be sufficient to overcomefragmentation of financial markets because of structural andinstitutional barriers to interactions across different marketsegments. The four countries have substantially fragmented financialmarkets, with weak linkages between formal and informal segmentsand interest rate differentials that cannot be adequately explainedby differences in costs and risks. Nevertheless, the relativelylow transaction costs and loan losses of informal institutionsindicate that they provide a reasonably efficient solution toinformation, transaction cost, and enforcement problems thatexclude their clients from access to formal banking services.The findings imply that financial liberalization and bank restructuringin the African context should be accompanied by complementarymeasures to address institutional and structural problems, suchas contract enforcement and information availability, and toimprove the integration of informal and formal financial markets.     

Valuing Mortgage Insurance Contracts in Emerging Market Economies

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract.     

Financial Support from the Family Network and Illegal Immigration

Barriers to immigration of low‐skilled workers from developing countries into the advanced countries prevent many potential migrants from leaving their countries of origin. With very low home‐country wages in relation to the cost of undocumented migration, the opportunity to migrate often hinges on the possibility of obtaining credit from a human smuggling organization or family and friends. This paper examines the conditions under which migration is optimal for an individual who lacks liquid assets, with a focus on alternative options for financing migration costs. One is by accumulating the required amount of savings out of source‐country income, with or without financial support from the family or social network. The other is debt‐bonded migration, which involves borrowing from a smuggling organization and paying off the loan while working in the host country. I find that greater financial support from the family network increases the attractiveness of debt‐bonded relative to self‐financed migration.
