Social Planner’s Solution for the Caspian Sea Conflict

This paper evaluates the proposed alternatives for sharing the Caspian Sea from the social planner’s or systems-level perspective with respect to the stakeholders’ utilities from the oil and natural gas resources of the sea. Different multi-criteria decision-making methods, namely dominance, maximin, lexicography, simple additive weighting, and TOPSIS are applied to determine the social planner’s ranking of these alternatives. Results suggest the Condominium governance regime as the most promising division method. Bankruptcy rules and cooperative game theory methods can be considered as the other socially optimal resolutions to the conflict over sharing the Caspian Sea energy resources among its five littoral countries. Consideration of these methods in negotiations may help with resolving the existing deadlock, which has been in place for two decades.     

Intercountry evidence on the performance of the simple error correction mechanism model of consumption

This paper estimates a simple error correction mechanism (SECM) model of consumption a la Davidson, Hendry, Srba and Yeo (1978) for 13 OECD countries over the period 1951–1982. This is done for each country separately as well as for the pooled data. The basic results of this study are the following: (i) The SECM model appears as an adequate approximation to the data generating process on an individual country basis as well as in a pooled context. (ii) The pooled within estimator indicates a large and significant disequilibrium term while the between estimator indicates a small and insignificant disequilibrium term. This is consistent with the belief that the within estimator tend to yield short-run estimates while the between estimator tend to yield long-run estimates.The authors would like to thank Baldev Raj and an anonymous referee for helpful comments and suggestions.

The Credit Crunch and Insider Trading

This paper examines the behaviour and information content of insiders’ trades before and after the credit crunch and, in particular, examines the extent to which some insiders anticipated the market crash and took action to protect their positions. In part, the market crash was brought about by the excessive borrowing of financial institutions. Our results point to the view that a number of insiders, primarily directors, were aware that the excessive use of leverage by financial institutions would ultimately have a detrimental impact on the economy. These insiders acted by selling their shares prior to the market collapse and subsequently buying them back at a lower price. Supportive evidence for the above view is provided through both graphical evidence and regression analysis. In particular, we demonstrate a link between insider behaviour and the rapid decline in share values. Further evidence is also provided of a link between insider behaviour and future risk as measured by the CDS premium. In short, we argue that this selling was not motivated by liquidity or other contrarian strategies but was a result of understanding how higher levels of leverage and excessive trading in new risky derivatives could lead to higher levels of risk, an insight possessed only by a subset of insiders.     

Testing for liquidity constraints among households: An international analysis

A testable implication for optimizing households minimizing a dynamic loss function but encountering borrowing constraints is forwarded. It is argued that in an error correction model of consumers' expenditures, an asymmetric reaction by households to disequilibrium error reveals the presence of borrowing constraints in the market. A test of this implication for the 11 OECD countries shows that significant liquidity constraints are present for most countries. The proposed setup can be used to test the previously maintained assumption of symmetric reactions to disequilibrium errors in the ECM models.     

Epidemiology of unintentional drowning in a metropolis of the French Mediterranean coast: a retrospective analysis (2000–2011)

Drowning affects more than 500,000 people worldwide and is responsible for at least 350,000 deaths each year. In France, 1235 drowning resulting in 496 deaths were recorded in the summer 2012. This retrospective study has investigated the epidemiology of drowning in the city of Marseille (South of France) between 2000 and 2011. We identified 449 cases of unintentional drowning. The highest incidence was found among males with a median age of 36 years. The incidence was 5.3 victims per 10,000 inhabitants with a mortality rate of 1.2 per 10,000. These accidents occurred mainly at sea (89%) and during the summer season. A majority of drowning victims (69%) were admitted in a hospital. This is the only study in France to analyse data on drowning throughout the year and over a long period. Drowning is a serious condition burdened by 22% of victims who die.     

Insider trading and future stock returns in firms with concentrated ownership levels

We investigate the relationship between insider trading and stock returns in firms with concentrated ownership. To this end, we employ data from East Asian countries which span the period January 2003 to May 2012. Consistent with the previous literature, we find a significantly negative relation between the selling activity of insiders and stock returns. However, contrary to studies which focus on highly developed markets, we find that the buying activity of insiders is also inversely related to future stock returns. Our analysis shows that top directors with higher ownership levels drive this result, suggesting that the trading activity of insiders is not always associated with profit-making motives and can be explained by their level of ownership. Furthermore, we demonstrate that a trading strategy which focuses solely on purchases made by top directors with high ownership levels yields negative returns. The paper has important implications for outside investors who mimic the trading activity of insiders with the aim to realise profits.     

Do Competing Health Insurance Licensors Provide Pro-patient Effects?

This paper shows that competition among health insurance licensors has strong pro-patient effects, if inter-regulatory competition is allowed. The pro-patient effects of the competition among health insurance licensors do not depend on the need for the patients to form or exercise their political influence, such as, forming cooperatives or voting, as suggested by Backer's pressure group theory. When inter-jurisdictional transactions are allowed, endogenous policy making ensures that the health care licensors pursue public interests at no costs to patients.     

Reducing informal payments in the health care system: Evidence from a large patient satisfaction survey

Paucity of information on the informal market for health services hampers the governments’ efforts in performing their desirable roles in informing, regulating, mandating, financing and providing health services to their people. Analysis of data from a survey of almost 20,000 patients fills a void in understanding informal payments in the countries in transition. A probability model of informal payments shows that knowledge and information have significant impact on reducing frequency of informal payments. Thus, informing patients, which is the least expensive and intrusive role of the government, could significantly reduce out-of-pocket health care spending.     

Corruption: Theory and evidence from the Russian Federation

In this paper, we provide theory and evidence on the problem of corruption in the Russian Federation. Our theoretical model indicates that in the presence of official corruption, the numbers of tax inspection (collection) employees could be inversely related to per capita tax collection. Our empirical analysis supports our theoretical model, shedding light on one of the most intractable problems in the Russian Federation.     

The dynamics of land-use/transportation interactions and their planning implications

The purpose of this study is to explore theoretically the qualitative impacts of the planning and development processes on the spatial dynamic interactions between land use and transportation. Specifically, an idealized abstract example of the interactions between two homogeneous regions was studied with respect to various issues related to land use and transportation planning. The study took the form of systems of simple differential equations. Each equation represents the rate of change of either the land use or the transportation condition of a region. Investigation with the two-region model suggested a possibility of spatial and temporal fluctuations under certain planning conditions. By examining the conditions underlying the model equations, planning and developmental practices that may cause system instabilities were identified and discussed.
