36 FACULTY OF FOOD AND AGRICULTURE Professor of Agricultural Economics Department of Agricultural Economics and Extension Tel 868 662 2002 ext. 83561 Fax 868 663 0515 E-mail PROF. MATTIAS BOMAN My interest in economics started as a rather biologically oriented undergraduate forestry student taking courses in microeconom- ics forest economics and natural resource economics. This curiosity in turn led to doctoral studies in forest economics and further advancement in the field of environmental and natural resource economics at the Swedish University of Agricultural Sciences SLU the National Institute of Economic Research NIER in Stockholm Sweden and more recently the University of the West Indies Trinidad and Tobago. It should be said at the outset that most of my research work has been collaborative efforts. I therefore write Imemy and weusour interchangeably in the following it being understood that I gratefully acknowledge all of my colleagues and co-authors over the years although the space here does not permit mentioning them all by name. Early on I worked primarily with different aspects of benefits costs and policy instruments applied to threatened species management. My first scientific publication concerned economic costs of various population densities of predators in Sweden.Building on thisI was interested in the social benefits of preserving a charismatic endangered predator in Sweden namely the wolf. With my colleagues I carried out a mail contin- gent valuation CV survey on the benefits of wolf preservation in Sweden.Moreover this study induced me to do methodologi- cal work concerning the CV method regarding nonparametric estimation in discrete response CV studies and nonresponse problems in mail CV surveys. Based on the collected benefit-cost data regarding the wolf we made use of the well-known Weitz- man 1974 proof to analyze the choice of policy instrument a tax or a quantitative regulation in endangered species management. My later work has involved a broadening of my interests towards economic issues in multiple-use of forests wildlife management and recreationfurther applications and methodo- logical aspects on environmental valuation the assessment and valuation of health effects from outdoor recreation resource accounting and cost-effectiveness in biodiversity conservation. One direction of my work on multiple-use has targeted the management of forests in northern Sweden where negative externalities and open access problems are present in timber production and reindeer grazing. Another direction of this research has dealt with the effects of non-timber benefits as well as price uncertainty on the optimal harvest strategies for a forest stand. Our work on wildlife management addressed the economic benefits of the selective moose hunting policy currently in practice in Swedenas well as the optimal geographi- cal distribution of a Swedish wolf population. The valuation studies have been focused empirically on the economic value of reaching national environmental objectives the value of broad- leaved forests for recreationthe value of hunting and other types of outdoor recreation. The empirical data was also used to address issues of preference uncertainty i.e. when respondents have incomplete knowledge about their true valuation tempo- ral stability and reliability of CV estimates and how income changes affect outdoor recreation expenditures i.e. the income elasticity.An integral part of the recreation studies has also been to compare the health effects from different types of outdoor recreation e.g. hunting and forest recreation suggesting that the removal of outdoor recreation opportunities would result in a decrease in average self-rated health. The study on national environmental objectives was also part of a larger effort on the use of the CV method in resource accounting at NIER. Another strand of our resource accounting work investigated to what extent stumpage prices may be reliable indicators of the scarcity of the forest resource stock in a country. Our studies on cost- effectiveness assessed the relative importance of including information about costs and benefits for commonly used conser- vation goals and compared strategies in reserve selection and the associated differences in cost-effectiveness. As a new member of The UWI being Deputy Dean and lecturer has given me valuable insights into the academic work of my colleagues at our faculty and the university at large. In collaborationI am hoping to contribute to this work in the future and have taken steps in that direction together with some of my colleagues. Our first analysis has been a general analysis of the sustainability of economic growth in Trinidad and Tobago presented at the Fifth World Congress of Environmental and Resource Economists in Istanbul Turkey. I hope this will be a stepping stone towards an expanding research agenda with many fruitful connections both inside and outside our faculty and campus. In conclusion my work has been aimed at improving the basis for environmental and natural resource management by increasing our knowledge on the externalities and conflicts surrounding goods and services not priced on ordinary markets. In my own capacity I have of course only been able to address p arts of these huge problems.These parts have been chosen partly from my own scientific curiosity and partly in order to best complement the efforts of the scientific community at large
