The U.S./EU Beef Controversy and a Proposed Framework for Resolving Standards Disputes in International Trade

While world trading institutions such as GATT and its successor, the WTO, have made significant progress in addressing tariff barriers as well as some non‐tariff barriers, trade disputes over product standards appear to be increasing in number and intensity. Product standards refer to measures governments take to ensure that products sold in their home market meet health, safety, and quality requirements consistent with the public interest. The longstanding controversy between the European Union and the United States over the export of hormone treated beef is used as a case study to illustrate the difficulty of resolving product standards disputes.     

Unit Versus Ad Valorem Taxes: The Private Ownership of Monopoly in General Equilibrium

Employing a general equilibrium framework, Blackorby and Murty prove that, with a monopoly and under 100% profit taxation and uniform lump‐sum transfers, the utility possibility sets of economies with unit and ad valorem taxes are identical. This welfare equivalence is in contrast to most previous studies, which demonstrate the superiority of the ad valorem tax in a partial equilibrium framework. In this paper, we relax the assumption of 100% profit taxation and allow the consumers to receive profit incomes from ownership of shares in the monopoly firm. We find that, under certain regularity conditions, for any fixed vector of profit shares, the utility possibility sets of economies with unit and ad valorem taxes are not generally identical. But it does not imply that one completely dominates the other. Rather, the two utility possibility frontiers cross each other. Additionally, employing a standard partial equilibrium welfare analysis, we show that the Marshallian social surpluses resulting from the two tax structures are identical when the government can implement unrestricted transfers.     

A Comparative‐Advantage Approach to Government Debt Maturity

We study optimal government debt maturity in a model where investors derive monetary services from holding riskless short‐term securities. In a setting where the government is the only issuer of such riskless paper, it trades off the monetary premium associated with short‐term debt against the refinancing risk implied by the need to roll over its debt more often. We extend the model to allow private financial intermediaries to compete with the government in the provision of short‐term money‐like claims. We argue that, if there are negative externalities associated with private money creation, the government should tilt its issuance more toward short maturities, thereby partially crowding out the private sector's use of short‐term debt.     

Taming Systemically Important Financial Institutions

We model a systemically important financial institution that is too big (or too interconnected) to fail. Without credible regulation and strong supervision, the shareholders of this institution might deliberately let its managers take excessive risk. We propose a solution to this problem, showing how insurance against systemic shocks can be provided without generating moral hazard. The solution involves levying a systemic tax needed to cover the costs of future crises and more importantly establishing a systemic risk authority endowed with special resolution powers, including the control of bankers’ compensation packages during crisis periods.
