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.

The changing relationship between earnings expectations and earnings for value and growth stocks during Reg FD

Regulation Fair Disclosure (Reg FD) altered the voluntary disclosure practices of firms with publicly traded securities, thereby affecting relationships between value and growth stock expectations and actual earnings. The results show that earnings forecasts for both stock groups are biased but that bias is less after the introduction of Reg FD. In fact, the difference in pre/post FD forecast bias is larger for growth stocks, suggesting that before Reg FD, analysts did not just misinterpret news but consciously tried to maintain relationships with growth firm managers. However, Reg FD limited these relationships severing the monetary advantage that might be gained from manipulating forecasts.     

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.     

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.     

Human capital revisited: The role of experience and education when controlling for performance and cognitive skills

Human capital theory predicts that differences in wages arise because of differences in human capital. The latter can be accumulated in two ways: through experience and education. Using matched firm–worker data for the Ghanaian Manufacturing sector we first test whether changes in wages over the life cycle reflect changes in performance, following the methodology of Medoff and Abraham [Medoff, J.L., &; Abraham, K.G. (1980). Experience, Performance, and Earnings. Quarterly Journal of Economics, 95(4), 703-736; Medoff, J.L., &; Abraham, K.G. (1981). Are Those Paid More Really More Productive? The Case of Experience. Journal of Human Resources, 16(2), 186–216]. We find that wage–seniority profiles are independent of performance – a result that holds when controlling for firm fixed effects. Extending the analysis, we include a control for on-the-job-training and find that it does not attenuate the seniority profile, which is also at odds with human capital theory. We do find however that firm characteristics play an important role. Wage–seniority profiles are steeper in large firms, but performance profiles are not, suggesting that the results from Medoff and Abraham are specific to large firms. We then assess the role of education. Our results confirm that education is important for the allocation to job levels. Using data on cognitive ability, we also find that the effect of education on wages is at least partially because it signals cognitive ability. We also find evidence that the returns to education are not related to performance, while the returns to cognitive ability are.
