A 2-phase research effort is summarized. The first phase is concerned with measurement of the economic changes consequent to the introduction of various air pollution control policies. Areas of specific concern in this phase are as follows: the pollution production function; measurement of the costs of regulating open field burning in the Willamette Valley; the impact of air quality variations on tourist related industries. The second phase deals with social effects. A theoretical model concerning the effects of air quality changes on peoples attitudes and mass media use patterns has been formulated as a means of measurement of change. Each of the following objectives which relate to this model, are discussed: completion of interviews and evaluation of response rates; completion of coding, key punching and varification; completion of visibility measures; analysis of air quality perceptions of respondents; analysis planned for the forthcoming year.
