Intertemporal market division:: A case of alternating monopoly

In this paper, we report on an equilibrium with market dominance that exists in a simple two-firm model that features neither entry barriers nor sophisticated punishment strategies. This equilibrium induces an intertemporal market division in which the two firms alternate as monopolists - despite the fact that the model also sustains a Cournot duopoly. Even when initially both firms are active in the market, the alternating monopoly reveals itself rather quickly. Moreover, it Pareto dominates the Cournot equilibrium - as it is close to the cartel outcome. Several examples of what well may be such alternating monopolies are presented.     

Requests for zoo visitors to undertake pro-wildlife behaviour: How many is too many?

Recognising the potential conservation impact, zoos regularly ask their visitors to undertake pro-wildlife behaviour. This paper presents the results of two studies undertaken to address the question: how often during a visit should visitors be asked? Study 1 sought to a) determine individuals' personal thresholds and b) the point where the number of different behaviours requested began affect visitors' experiences. Study 2 sought the same, but focused on requests for the same behaviour. Results suggest that few respondents' personal thresholds were crossed (2.5% in Study 1 and 9% in Study 2). In neither study did many respondents (2.5% in Study 1 and 2.8% in Study 2) feel that the number of requests negatively affect their overall zoo experience. While there are caveats, we conclude that there appears little cause for concern about asking zoo visitors on multiple occasions to act in support of wildlife. Indeed, such requests may improve experiences.     

Corporate ownership and control structures: An international comparison

This paper analyzes the economic fundamentals of the corporate firm with publicly held shares and the salient characteristics of varying corporate systems, focusing on international differences in ownership and control structures, including alternative disciplinary mechanisms. Those international differences seem to influence economic behavior and corporate performance, including the way in which corporate restructurings take place. Market-oriented corporate systems and network-oriented corporate systems are likely to mutually converge in the future.     

Optimal design of trade institutions

We model an economy with social institutions that facilitate trade and induce three types of costs: establishment costs, access costs, and use costs. Use costs are specific transaction costs related to the use of these trade institutions. We assume that a trade institution is economically completely determined by the costs it imposes and by the effects on the trades it facilitates. We extend the Pareto efficiency concept to include various modes of organization of social institutions: the costs and benefits of these organizations are expressed in the trades they facilitate.Within this setting we discuss a valuation equilibrium concept, in which all agents use a common conjectural price system that assigns to every trade institution the price vector that would prevail under it. This feature of the equilibrium is important in securing the second welfare theorem, and is new to the analysis of economies with costly trade. Since the use costs can be nonlinear, there are non-convexities that prevent the second welfare theorem from obtaining in a finite economy, but we show it for large economies.Received: 3 April 2002, Accepted: 30 April 2003, JEL Classification: D59, D70, H49Robert P.

FINANCIAL CHARACTERISTICS RELATED TO MANAGEMENTS'STOCK SPLIT AND STOCK DIVIDEND DECISIONS

Several studies have made inquiries of corporate managers concerning their motivations for undertaking stock splits and stock dividends. This paper investigates whether the factors identified by these studies are in fact associated with the actual stock distribution decisions of managers. The results are consistent with the view that managements issue large stock distributions (25 per cent or greater) in order to keep the per share price in an optimal range and to signal optimistic expectations to the market. Firms with relatively low per share prices were inclined to issue small stock distributions (less than 25 per cent); the signaling motivation also played a role here.     

On dynamic selection of households for direct marketing based on Markov chain models with memory

A simple, dynamic selection procedure is proposed, based on conditional, expected profits using Markov chain models with memory. The method is easy to apply, only frequencies and mean values have to be calculated or estimated. The method is empirically illustrated using a data set from a charitable foundation. The results reveal some interesting features with respect to the time-dependent behavior of certain subsets of households, whereas the profitability increases by about 9% by using the method compared to a benchmark of sending a mailing to all households.     

Toward a Comprehensive Framework of Study Abroad Intentions and Behaviors

Increased activity by U.S. students to study abroad has invited several studies that have investigated the reasons for U.S. students to study abroad. Literature in the context of study abroad choices has been fragmented, with each study presenting an ad-hoc set of factors the author/s deem as important or that have been shown to be important in previous literature. However, no study to date has attempted to identify a theoretical framework that explains why these factors should be important in explaining the intention to participate in a study abroad program. In this study, we use the theoretical background of the Theory of Planned Behavior (TPB) and trait theory to unify the existing body of literature and arrive at a model that predicts study abroad intentions. We test this model by means of a survey administered in a U.S. university.     

From Returns to Tweets and Back: An Investigation of the Stocks in the Dow Jones Industrial Average

A sizeable percentage of investors are using social media to obtain information about companies (Cogent Research [2008]). As a consequence, social media content about firms may have an impact on stock prices (Hachman [2011]). Various studies utilize social media content to forecast stock market-related factors such as returns, volatility, or trading volume. The objective of this article is to investigate whether a bidirectional intraday relationship between stock returns and volatility and tweets exists. The study analyzed 150,180 minute-by-minute stock price and tweet data for the 30 stocks in the Dow Jones Industrial Average over a random 13-day interval from June 2 to June 18, 2014 using a BEKK-MVGARCH methodology. Findings indicate that 87% of stock returns are influenced by lagged innovations of the tweets data, but there is little evidence to support that the direction is reciprocal, with only 7% of tweets being influenced by lagged innovations of the stock returns. Results further show that the lagged innovations from 40 percent of stock returns affect the current conditional volatility of the tweets, while 73 percent of tweets affect the current conditional volatility of stock returns. Moreover, there is strong evidence to suggest that the volatility originating from the returns to the tweets persists for 33 percent of stocks; the volatility originating from the tweets to the returns persists for 73 percent of stocks. Last, 53 percent of stocks exhibit both immediate and persistent impacts from returns to tweets, while 90 percent of stocks exhibit both immediate and persistent impacts from tweets to returns. These results may help traders achieve superior returns by buying and selling individual stocks or options. Also, asset and mutual fund managers may benefit by developing a social media strategy.     

Preparing Russian Small Innovative Enterprises for International Competitiveness: A Scoping Study

Russian small innovative enterprises (SIEs) are emerging as an important force behind the restructuring of the Russian economy and its industrial and commercial infrastructure. The research presented in this paper suggests that there are at least three categories of factors that impact the move of Russian SIEs into international markets: (i) macro-economic obstacles (ii) lacking managerial and business competencies and (iii) differences in culture and business practices. The first factor cannot be directly influenced by the individual SIE, while the latter two represent opportunities of a developmental nature. The work of this paper purports to lay the groundwork for more theoretical follow-up analyses.
