Research communication

In this paper we review briefly histories and ideologies underlying multiculturalism in Nordic countries, highlighting tensions between integrationist and inclusive approaches. We propose a cultural ecological framework through which we discuss the possibility of a transculturalism based on Fourth World engagement with the environment. Cultural ecology is about the reciprocal interactions and transactions between people and their environments. The Fourth World is a circum-global, pan-arctic region which includes the northern parts of some Nordic countries. We argue that whether or not there is a distinctively Nordic version of multiculturalism, Nordic countries have access to Fourth World ways of engaging with the environment which transcend notions of inter- and multiculturalism and the ideological tensions associated with them

Multinationals and the Gains from International Diversification

One possible explanation for home bias is that investors may obtain indirect international diversification benefits by investing in multinational firms rather than by investing directly in foreign markets. This paper employs mean-variance spanning tests to examine the diversification potential of multinational firms and foreign market indices for investors domiciled in Canada, France, Germany, Italy, Japan, the United Kingdom and the United States. We find that in most countries and most time periods, the portfolio of domestic stocks spans the risk and return opportunities of a portfolio that includes domestic and multinational stocks. However, there is weak evidence that U.S. multinationals provided global diversification benefits in the full 1984-92 sample and in the post-1987 subsample. We also find that the addition of foreign market indices to a domestic portfolio - inclusive of multinationals - provides diversification benefits. The economic importance of the shift of the portfolio frontier - measured as the utility gain from diversification - varies considerably from market to market and often reflects the benefits of large short positions in certain markets.

Bioeconomic modeling of wetlands and waterfowl in Western Canada: Accounting for amenity values

This study extends an original bioeconomic model of optimal duck harvest and wetland retention by bringing in amenity values related to the nonmarket (in situ) benefits of waterfowl plsi the ecosystem values of wetlands themselves. The model maximizes benefits to hunters as well as the amenity values of ducks and ecosystem benefits of wetlands, subject to the population dynamics. Results indicate that wetlands and duck harvests need to be increased relative to historical levels. Further, the socially optimal ratio of duck harvest to wetlands is larger than what has been observed historically. Including amenity values leads to a significant increase in the quantity of wetlands and duck harvests relative to models that focus only on hunting values.bioeconomic modelling, wetland protection, wildlife management, nonmarket values, Prairie pothole region, Environmental Economics and Policy, Q57, C61, Q25,
