Influence of On-Site Choices on Recreation Demand

Eleven conceptual models that illustrate the relationship between ethnicity/race and recreation are examined. From Lindsay and Ogle (1972) to Floyd, Gramman, and Saenz (1993), the reader is taken through the array of theoretical models that have been used to determine recreation participation by ethnic/racial groups in America. A new conceptual model is created that incorporates elements from each of the previous 11 models. This new model is termed the Ethnicity and Public Recreation Participation Model (EPRP Model) © . The EPRP Model is introduced as a viable theoretical framework for studying and measuring the relationship between ethnic/racial factors and recreation participation.     

Examining sustainability performance in the supply chain: The case of the Greek dairy sector

This paper evaluates the sustainability performance of the Greek dairy chain and the performance of its individual members by using key indicators in relation to efficiency, flexibility, responsiveness and product quality. We assessed the importance of these indicators based on the relevant perceptions of key members of this chain. A structured questionnaire was developed where nineteen sustainability-related issues were examined. Two hundred and fifty three members of the Greek dairy supply chain responded including breeders, manufacturers, wholesalers, retailers and catering companies. Our findings illustrate the immediate need for improvement in many key sustainability performance indicators. They also show the critical role of large dairy manufacturers who are the “sustainability performance champions” in this chain and are the driving force for the implementation of many sustainability initiatives.     

Towards a More ‘Ethically Correct’ Governance for Economic Sustainability

In this paper, we propose that economic sustainability is seen in terms of (inter-temporal and inter-national) value creation. We claim that value appropriation (or capture), can become a constraint to economic sustainability. We propose that for sustainable value creation to be fostered, corporate governance needs to be aligned to public and supra-national governance. In order to achieve this, a hierarchically layered set of ‘agencies’, needs to be diagnosed and the issue of incentive alignment addressed. Enlightened self-interest, pluralism and diversity, as well as a representative supra-national organisation for world-wide economic sustainability can serve as a new, more ‘ethically correct’ governance for economic sustainability, but not a panacea.     

Fiscal risk in a monetary union

We present a dynamic and quantitative model of a fiscal solvency crisis in a monetary union. Diverse fiscal policies, which are subject to fiscal limits and stochastic shocks, can threaten a monetary union. The fiscal limits arise due to distortionary taxation and political will. Stochastic shocks are random and could push a fiscally sound policy towards its limit. In equilibrium agents refuse to lend along a path which violates the fiscal limits, creating a fiscal solvency crisis. The dynamics leading to the crisis depend on the policy response to restore lending. We focus on two responses, default and policy switching. We simulate our model to quantify the probability of a fiscal solvency crisis in the European Monetary Union with fiscal variables at end of 2009 values. Our model predicts the Greek crisis which occurred and warns of an Italian one.     

NONREPLICATION OF OPTIONS

In this paper, we study the replication of options in security markets X with a finite number of states. Specifically, we prove that in security markets without binary vectors, for any portfolio, at most m ? 3 options can be replicated where m is the number of states. This is an essential improvement of the result of Baptista where it is proved that the set of replicated options is of measure zero. Additionally, we extend the results of Aliprantis and Tourky on the nonreplication of options by generalizing their condition that markets are strongly resolving. Our results are based on the theory of lattice‐subspaces and positive bases.     

Earnings conservatism: panel data evidence from the European Union and the United States

This paper focuses on earnings conservatism, and provides new evidence based on procedures that account for variability at the firm level, drawing a comparison between the European Union and the United States. A key finding is that the estimated responsiveness of earnings to bad news is substantially higher when unobserved firm-specific effects are modelled. Furthermore, it is shown that accounting has become more conservative not only in the U.S. but also in the EU when taken as a whole, and there is little evidence of marked differences in the asymmetric timeliness of earnings between the two. Indeed, any changes in this property of earnings are likely to be attributable to a common factor that influences firms similarly in both locations, and not necessarily to the process of economic convergence that has taken place in the EU.     

The Time Series Properties of Financial Ratios: Lev Revisited

This paper re‐evaluates the time series properties of financial ratios. It presents new empirical analysis which explicitly allows for the possibility that financial ratios can be characterized as non‐linear mean‐reverting processes. Financial ratios are widely employed as explanatory variables in accounting and finance research with applications ranging from the determinants of auditors' compensation to explaining firms' investment decisions. An implicit assumption in this empirical work is that the ratios are stationary so that the postulated models can be estimated by classical regression methods. However, recent empirical work on the time series properties of corporate financial ratios has reported that the level of the majority of ratios is described by non‐stationary, I (1), integrated processes and that the ratio differences are parsimoniously described by random walks. We hypothesize that financial ratios may follow a random walk near their target level, but that the more distant a ratio is from target, the more likely the firm is to take remedial action to bring it back towards target. This behavior will result in a significant size distortion of the conventional stationarity tests and lead to frequent non‐rejection of the null hypothesis of non‐stationarity, a finding which undermines the use of these ratios as reliable conditioning variables for the explanation of firms' decisions.     

Barriers to Mobility in Europe's Civil Aviation Markets: Theory and New Evidence

A questionnaire-based survey is applied to investigate the perception of mobilitybarriers by European airline managers. Whilst the liberalisation of Europe's airline markets removed regulatory mobility barriers, we find that mobility impediments still appear to exist. Potential entrants moreover, perceive some mobility barriers as significantly more effective than others. The perceived effectiveness of a particular mobility barrier varies considerably among airline managers. We also provide an overview of previous studies on the contestability hypothesis and the effectiveness of endogenous (strategic) mobility barriers. Our results support earlier findings for the U.S. to the effect that barriers to mobility are perceived to exist and matter. Whilst our results are clearly subjective, as they are based on the perceptions of managers, we believe such perceptions matter as they inform managerial actions. In this sensewe believe our results are of value.     

U.S. Common stock prices, 1871–1970: playing with dummies

The received wisdom that the levels of many economic time series are generated by processes with a unit autoregressive root has been called into question by recent work of Perron. When break points, or interventions, in the time series are allowed it emerges that the unit roots hypothesis can often be rejected at quite low significance levels. Taking for illustration a single time series, U.S. common stock prices, we demonstrate that Perron's conclusions are very sensitive to the choice of break point, and that the data contain little support for the particular choice imposed by Perron.     

Using the extended innovation attributes framework and consumer personal characteristics as predictors of internet banking adoption

The presumed dominant role of usability attributes (ie usefulness and ease of use) in predicting consumer adoption of a technologically based innovation (eg internet banking — IB) is reexamined, by using an extended framework, which, apart from usability, incorporates the social and psychological aspects of the adoption process. Furthermore, given that IB has been around for almost a decade, it is high time to update the profile of the potential adopters. Results, underscore the role of social factors as predictors of potential IB adopters, whereas the demographic profile of future IB adopters displays important differences compared to that of those already using IB. Possible explanations are discussed, along with implication for practitioners and suggestions for future research.
