The gap between the qualifications of New York City teachers in high-poverty schools and low-poverty schools has narrowed substantially since 2000. Most of this gap-narrowing resulted from changes in the characteristics of newly hired teachers, and largely has been driven by the virtual elimination of newly hired uncertified teachers coupled with an influx of teachers with strong academic backgrounds in the Teaching Fellows program and Teach for America.

Under U.S. GAAP, reported balance sheet and income statements are based on immediate expensing of R&D expenditures. We capitalize those expenditures and derive adjusted equity book values and earnings using simple amortization techniques (straight-line over assumed industry-specific useful lives). After confirming that such adjustments increase the association of book values/earnings with contemporaneous stock prices (and future earnings), we examine the relation between those adjustments and future returns.

This paper examines two related issues: (a) the implicit methodology used by the U.S. Treasury in determining whether China and America's other trading partners manipulate their exchange rates, and (b) the nature of the Chinese exchange rate regime since July 2005.

While new conventional wisdom warns that developing countries should be aware of the risks of premature capital account liberalization, the costs of not removing exchange controls have received much less attention. This paper investigates the negative effects of exchange controls on trade. To minimize evasion of controls, countries often intensify inspections at the border and increase documentation requirements. Thus, the cost of conducting trade rises.

This paper furnishes robust evidence that the WTO has had a strong positive impact on trade, amounting to about 120 percent of additional world trade (or US$ 8 trillion in 2000 alone). The impact has, however, been uneven. This, in many ways, is consistent with theoretical models of the GATT/WTO. The theory suggests that the impact of a country's membership in the GATT/WTO depends on what the country does with its membership, with whom it negotiates, and which products the negotiation covers.

Standard valuation methods do not lend themselves to bank holding companies. Banks create value through the types of assets and liabilities they create (e.g., lending and deposit taking relationships). Bank income streams reflect heterogeneous sources of income which differ in their margins of profitability and persistence.

This book by a leading authority on monetary policy offers a unique view of the subject from the perspectives of both scholar and practitioner. Frederic Mishkin is not only an academic expert in the field but also has been a high-level policymaker. He is especially well positioned to discuss the changes in the conduct of monetary policy in recent years, in particular the turn to inflation targeting.

This paper studies the application of fair value accounting in bank holding companies in the United States with the purpose of evaluating the effects of expanding fair value accounting in the banking industry.

Weak public institutions, including high levels of corruption, characterize many developing countries. We demonstrate that this feature has important implications for the design of monetary policymaking institutions. We find that a pegged exchange rate or dollarization, while sometimes prescribed as a solution to the credibility problem, is typically not appropriate for countries with poor institutions. Such an arrangement is inferior to a Rogoff-style conservative central banker, whose optimal degree of conservatism is proportional to the quality of institutions.
