Pricing, price dispersion, and information: The discount brokerage industry

The paper provides an empirical analysis of the pricing behavior of firms within the discount brokerage industry, with emphasis on testing the role of costly information in affecting prices. Several empirical tests are performed that indicate that prices in this industry respond in ways hypothesized by theoretical models of markets operating under conditions of imperfect information. The industry is characterized by a wide degree of price dispersion that does not appear to simply reflect quality differences among firms. In addition, the variance of prices across geographic markets is associated with variables that theoretically should affect the levels of consumer information in those markets.     

THE INFLUENCE OF FIRM‐ AND CEO‐SPECIFIC CHARACTERISTICS ON THE USE OF NONLINEAR DERIVATIVE INSTRUMENTS

We examine why firms use nonlinear derivatives (e.g., options). Our results suggest that option characteristics in investment opportunities and debt, the payoff structure of incentive compensation, and free cash‐flow agency problems influence the firm's choice. Investment opportunities, internally generated cash flow, business risk, and option compensation positively influence the use of nonlinear currency derivatives. Option feature in bonds positively influence the use of nonlinear interest rate derivatives, whereas bonus and stock compensation, and CEO tenure have a negative influence. In sum, nonlinear cash flow characteristics in investment opportunity, debt, and executive compensation all relate positively to nonlinear derivative usage.     

Science and technology forecasting today: Features of its methodology and object

The paper examines methodological and subject aspects of some problem questions that arise in organizing and technologization a long-term forecast procedure. It looks at the basic elements of the methodology and technique of a long-term forecast performed during the development of the Concept for Long-term Socioeconomic Development of the Russian Federation. Key conditions for technology application in the framework of two possible scenarios of Russian economic growth, primary-and-energy and innovation-active, are analyzed.     

AN EVALUATION OF ALTERNATIVE APPROACHES TO MARKET SHARE ANALYSIS WITH APPLICATION TO THE KUWAITI POULTRY MARKET

Changes in exporter market shares in the Kuwaiti poultry import market over the period 1971–81 are analysed by three modelling procedures. Two traditional approaches, a first-order constant transition probability Markov model and a set of market share equations, are found to be of only limited use. As an alternative, a multinominal logit model of market share behaviour is estimated. The empirical results indicate that, in addition to relative price changes, domestic policy inducements for Brazilian and European Community exports are important in determining market share changes. A comparison of the explanatory abilities of the models suggests that the multinominal logit model is as least as good as traditional modelling alternatives with respect to econometric criteria. It is concluded that the multinominal logit model offers considerable promise as a tool for market share research.     

Kappa as a measure of pattern in sequential data

The kappa statistic is suggested as a means to index the degree to which particular patterns occur in social interaction. It is suggested that the value of the kappa statistic for each interaction be used as a dependent measure. Particular formulas for kappa are derived for undirectional dependence, bidirectional dependence, other additive patterns, and for dominance.
