TAXATION, FINES, AND PRODUCER LIABILITY RULES: EFFICIENCY AND MARKET STRUCTURE IMPLICATIONS
This paper addresses the comparative efficiency of liability rules and regulatory policy in competitive equilibria with endogenous product safety. Pigouvian taxation fails to achieve long-run social optimality. A policy involving accident fines and safety subsidization can achieve efficiency, although the optimal policy may involve taxation, not subsidization, of product safety.Public Economics,

Vertical Structure and Strategic Environmental Trade Policy
The idea that environmental trade policy may be used to achieve competitive advantage in international markets has important implications for the way we conceive tree-trade. This paper reconsiders the issue of strategic environmental policy in a model that makes explicit the vertical structure that supports production of the traded good. We find these intranational vertical relationships to have a substantial qualitative effect on the optimal strategic environmental trade policy. We show that under both quantity and price competition in the international market, the optimal policy to levy on the polluting input when vertical contracts are allowed is a Pigouvian tax.strategic trade, vertical contracts, environmental policy
Slotting Allowances and Retail Product Variety under Oligopoly
Slotting fees are fixed charges paid by food manufacturers to retailers for access to the retail market. The role of the practice and its effects on market efficiency are highly controversial. To date, the literature has focused on the effect of the practice on retail prices; however, slotting allowances also have the potential to alter the range of products available to consumers. Our analysis reveals that the strategic use of slotting allowances by oligopoly firms leads to a superior allocation of product variety among retailers. Indeed, absent price effects, we show that slotting allowances lead to the socially optimal provision of product variety.Slotting fees, vertical contracts, monopolization., Agribusiness, Agricultural and Food Policy, Industrial Organization, Marketing, L13, L14, L42, D43,
Charge shelving and bias spectroscopy for the readout of a charge-qubit on the basis of superposition states
Charge-based qubits have been proposed as fundamental elements for quantum
computers. One commonly proposed readout device is the single-electron
transistor (SET). SETs can distinguish between localized charge states, but
lack the sensitivity to directly distinguish superposition states, which have
greatly enhanced coherence times compared with position states. We propose
introducing a third dot, and exploiting energy dependent tunnelling from the
qubit into this dot (bias spectroscopy) for pseudo-spin to charge conversion
and superposition basis readout. We introduce an adiabatic fast passage-style
charge pumping technique which enables efficient and robust readout via charge
shelving, avoiding problems due to finite SET measurement time.Comment: 4 pages, 3 figures, note slightly changed title, replaced with

BACKWARD IMPLICIT CONTRACTS, PRE-COMMITMENT AND MARKET POWER IN THE INTERNATIONAL DURUM WHEAT MARKET
We devise a formal test of market power that is applied to the international durum market. The model captures the asymmetric cost structure brought about the initial payment system of the Canadian Wheat Board. The model generates testable hypotheses about market conduct and optimal strategic positioning.Crop Production/Industries, Industrial Organization,
