Previous HPSG accounts of extraction blur the distinction between valents and adjuncts by allowing verbs to lexically control the modifiers that combine with their phrasal projections. However, assuming that adjuncts are valents runs into various difficulties. This paper argues that the distinction between complements and adjuncts can be maintained, and that certain semantic phenomena that challenge traceless theories of extraction can be seen as an instance of a more general process. Finally, this paper also discusses a uniform mechanism for case assignment to valents and adverbial nominals.

Amenities influence individual location decisions and affect overall social well being. This comparative study focuses on the potential complementarity of implicit and contingent market approaches to valuing amenities. Lakeshore residents in Chicago were surveyed to collect data to estimate implied housing hedonic values and contingent values for two view-related amenities. The consumers in the housing market and the bidders in the contingent market are the exact same people. Presumably differences in estimates are primarily due to the different approaches. For willingness to pay, contingent values are found to be within a factor of two of implicit values. The difference is consistent with sorting which occurs in the housing market. The results provide further evidence of progress in valuing amenities.
