External adjustment

Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national income and product account measure of the current account balance increasingly inadequate as a summary of the change in a country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain high on policymakers' list of concerns, even, for the richer and less credit-constrained countries. Extreme imbalances signal the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources of the change in net foreign assets—the current account and the capital gain on the net foreign asset position—the former is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset values in order to change the net foreign asset position could have a destabilizing effect on market expectations. JEL no.

Cognitive Theory and Moral Behavior: The Contribution of F. A. Hayek to Business Ethics

This paper shows how business ethics as a concept may be approached from a cognitive viewpoint. Following F. A. Hayek's cognitive theory, I argue that moral behavior evolves and changes because of individual perception and action. Individual moral behavior becomes a moral rule when prominently displayed by members of a certain society in a specific situation. A set of moral rules eventually forms the ethical code of a society, of which business ethics codes are only a part. By focusing on the concept of "limited" or "dispersed knowledge" that underlies the cognitive approach, I show that universal ethical norms that should lead to defined outcomes cannot exist. This approach moreover shows the limits of deliberate rule-setting. Attempts to deliberately impose universal ethical rules on societies may turn out to be harmful for societal development and lead to an abuse of governmental power.     

Effects of health information on Nordic meat and fish demand

Increasing public concerns about health risks associated with dietary intakes of cholesterol are expected to have significant impacts on the demand for foods with high fat content. This paper investigates how information about cholesterol, as measured by two newly constructed indices based on published medical research, has affected the demand for meats (beef, chicken and pork) and fish in the Nordic countries (Denmark, Finland, Norway and Sweden). To compare the effects of information across countries and over time, the demand equations for all the countries are estimated within one system, and a complete set of price and expenditure elasticities is estimated. Our findings suggest that health information has affected consumption in a healthy way in all countries studied except for Denmark. We find positive effects on the demand for chicken in Finland, Norway and Sweden and for fish in Finland and Sweden. A negative effect on the demand for beef in Sweden also is found.

东亚货币一体化中的中日韩货币组合选择

本文对东亚货币一体化的研究建立在最优货币区理论和OCA指数计量模型的基础上，目的在于判断东亚经济中起主导作用的中日韩三国是否可能展开双边或者多边的货币合作。经测算发现，在排除了原模型中部分不适用的决定因素后，中日韩三国货币的共同组合似乎是比较合适的选择。     

Theoretical activity in sustainable tourism research

There is growing recognition in tourism and sustainable tourism research of the need for a fuller engagement in theoretical activity. The paper examines how different research strategies in recent articles on sustainable tourism have advanced theoretical understanding in this research field. The articles advance thinking through ideas and concepts connected with political ecology, mobilities, transition pathways, and behavioural and systems change. They are evaluated using a typology of research strategies associated with theoretical work, using a broad perspective on this work. The research strategy typology was developed for the paper, and it is explained and illustrated. While the papers on sustainable tourism use a range of strategies associated with theoretical activity, there is only limited engagement with “big” social theories.
