Physical and Economic Consequences of Sea-Level Rise: A Coupled GIS and CGE Analysis Under Uncertainties

This paper develops a modelling framework that links GEMINI-E3, a multi-regional, multi-sectoral computable general equilibrium model with a cost-benefit analysis approach at local level using geographical information system tools to assess the physical and economic consequences of sea-level rise (SLR) in the twenty first century. A set of future scenarios is developed spanning the uncertainties related to global warming, the parameters of semi-empirical SLR estimates, and coastal developments (cropland, urban areas and population). The importance of incorporating uncertainties regarding coastal development is highlighted. The simulation results suggest that the potential development of future coastal areas is a greater source of uncertainty than the parameters of SLR itself in terms of the economic consequences of SLR. At global level, the economic impact of SLR could be significant when loss of productive land along with loss of capital and forced displacement of populations are considered. Furthermore, highly urbanised and densely populated coastal areas of South East Asia, Australia and New Zealand are likely to suffer significantly if no protective measures are taken. Hence, it is suggested that coastal areas needs to be protected to ameliorate the overall welfare cost across various regions.     

Estimation of zero-intelligence models by L1 data

A unit volume zero-intelligence (ZI) model is defined and the distribution of its L1 process is recursively described. Further, a generalized ZI model allowing non-unit market orders, shifts of quotes and general in-spread events is proposed and a formula for the conditional distribution of its quotes is given, together with a formula for price impact. For both the models, MLE estimators are formulated and shown to be consistent and asymptotically normal. Consequently, the estimators are applied to data of six US stocks from nine electronic markets. It is found that more complex variants of the models, despite being significant, do not give considerably better predictions than their simple versions with constant intensities.     

Transparency and the regulatory process in Europe and the United States: two research priorities

Transparency research related to the regulatory process would benefit most from two types of empirical studies. One batch of studies, described in the fifth section of this essay, would focus on the American states and the member states of the European Union to identify the factors that determine whether regulatory processes are more transparent and whether transparency is successful in improving regulations and the regulatory process. In other words, we need comparative state (for the US) and member state (for the EU) studies to develop metrics for the quality of regulations and the role of transparency is advancing or weakening the quality of regulations at the state (for the US) and member state (for the EU) level. The second batch of studies, described in the sixth section of this essay, would explore who uses the information currently provided at the levels of transparency currently available in regulatory processes at the European Union and federal government of the United States. Who benefits from transparency and how are they using the available transparency mechanisms?     

Uncertainty on survival probabilities and solvency capital requirement: application to long-term care insurance

In this paper, we focus on uncertainty issues on disabled lives survival probabilities of LTC insurance policyholders and its consequences on solvency capital requirement. Among the risks affecting long-term care portfolios, special attention is addressed to the table risk, i.e. the risk of unanticipated aggregate mortality, arising from the uncertainty in modeling LTC claimants survival law. The table risk can be thought as the risk of systematic deviations referring not only to a parameter risk but, as well, to any other sources leading to a misinterpretation of the life table resulting for example from an evolution of medical techniques or a change in rules of acceptance. In fine, the idea is to introduce the risk of systematic deviations arising from the uncertainty on the disabled lives death probabilities directly. We analyze the consequences of an error of appreciation on the disabled lives survival probabilities in terms of level of reserves and describe a framework in an Own Risk and Solvency Assessment perspective to measure the gap between the risk profile from the standard formula to the risk analysis specific to the organism.     

Interest rate dynamics and volatility transmission in the European short term interest rate market

This paper investigates the price and volatility relationship in European short-term interest rate markets. Cointegration analysis is used to analyse the long and short run relationship and a GARCH BEKK model is estimated to analyse the volatility transmission between the markets. The stability of the long run relationship is also examined using Bai and Perron (Econometrica 66(1),47–78, 1998, J Appl Econ 18(1):1–22, 2003) structural break methodology. The results show that the relationship between the EURIBOR spot deposit rate and the EURIBOR future contract has changed significantly since 2001 and several structural breaks are present in the 13 year sample period. During periods where there is a long run relationship present the spot deposit rate generally leads the future rate in price discovery. In the short run there is bi-directional causality present between the markets. There is also significant evidence of volatility transmission from the spot market to the futures market throughout the sample period.     

Persistence and the four‐factor model in the Australian funds market: a note

We investigate whether Australian fund managers are able to deliver persistent performance using Carhart’s (1997) four‐factor model. Short‐ and long‐term persistence is examined and the sample is also divided into unit trusts and superannuation funds. We do not find evidence of persistence in any sample of funds. We find that winner (loser) funds tend to hold past winner (loser) stocks. Winner and loser unit trusts both appear to have positive exposure to small stocks.     

Interaction of size,book‐to‐market and momentum effects in Australia

This study seeks to disentangle the effects of size, book‐to‐market and momentum on returns. Initial results show that each characteristic has a role in explaining returns, but that there is interaction between size and momentum, as well as between size and book‐to‐market. Three key findings emerge. First, the size premium is the strongest, particularly in the loser portfolios. Second, the value premium is generally limited to the smallest portfolios. Third, the momentum premium is evident for the large‐ and middle‐sized portfolios, but loser stocks significantly outperform winner stocks in the smallest size portfolio. When these interactions are controlled with multivariate regression, we find a significant negative average relation between size and returns, a significant positive average relation between book‐to‐market and returns, and a significant positive average relation between momentum and returns.     

The ERA: A Brave New World of Accountability for Australian University Accounting Schools

This study examines the potential impact of Excellence in Research for Australia (ERA) on Australian university accounting schools through a series of in-depth interviews with Heads of Schools. Using an institutional theory framework we find that the pending introduction of the ERA has brought about changes in school structures, processes and systems. A creeping isomorphism is apparent as evidenced by a sector-wide movement towards targeting publications in highly ranked North American journals. While participants were generally positive about the overall aims of the ERA many felt that it would marginalise non-mainstream research. Furthermore, they were of the opinion that the ERA would lead to a reduction in the standing of accounting schools within Australian universities relative to other disciplines.

Caring and Conflicted: Mothers’ Ethical Judgments about Consumption

Literature on consumer ethics tends to focus on issues within the public sphere, such as the environment, and treats other drivers of consumption decisions, such as family, as non-moral concerns. Consequently, an attitude–behaviour gap is viewed as a straightforward failure by consumers to act ethically. We argue that this is based upon a view of consumer behaviour as linear and unproblematic, and an approach to moral reasoning, arising from a stereotypically masculine understanding of morality, which foregrounds abstract principles. By demonstrating the importance of context to consumption decisions and articulating the impact of caring relationships, we highlight how such decisions are both complex and situated. This is particularly evident for decisions involving the needs of others, as occurs in family life. We argue that the incorporation of care ethics provides both theoretical insights and a more complete account of consumer ethics. This is explored empirically through an investigation of the ethical dilemmas arising from consumption decisions made by mothers of young children. Such decisions juxtapose an ethical consumption orientation (representing impartial concerns) with care for one’s child. Therefore, what has been previously considered a failure to act ethically may in fact be the outcome of complex decision making, which involves competing ethical considerations. We discuss the implications of our findings for theory and practice and how this approach to consumer ethics could be applied more widely.
