We discuss the nonparametric approach to profit efficiency analysis at the firm and industry levels in the absence of complete price information, and propose two new insights. First, choosing one commodity (whose price is known) as a numeraire good enables us to measure profit inefficiency in...

This paper models firms' entrepreneurial ability according to their ability to predict changes in productivity (i.e., their prediction ability), and derives an aggregate production function as a result of entrepreneurship. An increase in firms' prediction ability improves allocative efficiency...

This paper examines a particular aspect of entrepreneurship, namely firms' activities in adapting to idiosyncratic environmental changes by appropriately reallocating resources. It presents an empirical framework that examines the social value of firms' abilities to predict and adapt to the...

We study Bayesian mechanism design in situations where agents' information may be multi-dimensional, concentrating on mechanisms that lead to efficient allocations. Our main result is that a generalization of the well-known Vickrey-Clarke-Groves mechanism maximizes the planner's "revenue'' among...

In this paper the option value of waiting under scientific uncertainty will be derived using the difference between the geometric Brownian motion and the mean reverting process by applying contingent claim analysis. The results will be compared with those generated by either using a geometric...

La valutazione economica delle risorse naturali fornisce al decisore pubblico una base informativa ampia e condivisibile, in grado di orientarne efficacemente la decisione. Essa quindi può favorire il raggiungimento degli obiettivi di miglioramento e di integrazione ambientale che gli indirizzi...

This paper offers a critical review of natural resource valuation and points out the role of economic valuation in EU policy-making. First of all, we specify the meaning of the economic value of environmental amenities, illustrate the most reliable and often used economic valuation techniques,...

A seller with two objects faces a group of bidders who are subject to budget constraints. The objects have common values to all bidders, but need not be identical and may be either complements or substitutes. In a simple complete information setting we show: (1) if the objects are sold by means...

Using an urban land use model in which jobs and residences are spatially dispersed and mixed, we treat the general equilibrium of land, labor and product markets and the trade-off between labor supply, commuting and discretionary travel. We show that the decentralization of population and of...

When ability to avoid rent control is randomly distributed over landlords, housing may rise above its free market level. Landlords evading part of rent-control are like suppliers selling to a perfectly price-discriminating monopsonist. A continuum of evasive abilities gives a range of low rent...
