Despite the influx of measures which can be customized to the demands of each business unit (e.g., customer satisfaction surveys and quality indices), many firms have been dogged in their reliance on standardized measures (e.g., conventional financial metrics) in performance evaluation. In this paper, we consider one justification: though customized measures may more accurately target the goals of a particular unit, standardized measures may offer more meaningful opportunities for relative performance evaluation.

In the Public Company Accounting Oversight Board's Sep 2004 Standing Advisory Group Meeting, one of the sessions was devoted to verifiability concerns regarding fair values. At that meeting, some participants expressed the opinion that accounting estimates pose broader problems beyond computing fair values, and investors need to be educated about the role of estimates in financial statements. This paper suggests an extension to the existing accounting model to allow users to better understand the role of estimates/forecasts in financial statements.

Does country transparency affect international portfolio investment? We examine this question by constructing new measures of transparency and by making use of a unique microdata set on portfolio holdings of emerging market funds around the world. We distinguish between government and corporate transparency. There is clear evidence that funds systematically invest less in less transparent countries. Moreover, funds have a greater propensity to exit nontransparent countries during crises.

Since the beginning of the 1990s, we have seen a revolution in the way central banks communicate with the markets and the public. In the old days, central banks were generally very secretive institutions. Not only did they not clarify what their objectives and strategies were, but they even kept the markets guessing about what were the actual setting of policy instruments.

We investigate the ability of a tax-based fundamental –the ratio of tax-to-book income– to predict earnings growth and stock returns and to explain the earnings-price ratio. This tax fundamental reflects both temporary and permanent book-tax differences as well as tax accruals, such as changes in the tax valuation allowance. We find that the tax-to-book income ratio predicts subsequent five-year earnings changes, both before and after the implementation of Statement of Financial Accounting Standards (SFAS) No. 109 in 1993. For the pre-SFAS No.

Using pooled cross-sectional data from the Surveys of Consumer Finances, and new panel data from TIAA-CREF, we examine the empirical relationship between age and portfolio choice, focusing on the observed relationship between age and the fraction of wealth held in the stock market. We illustrate and discuss the importance of the well-known identification problem that prevents unrestricted estimation of age, time and cohort effects in longitudinal data.

This paper explores issues in emerging market countries to make inflation targeting work for them. It starts by outlining why emerging market economies are so different from advanced economies and then discuss why developing strong fiscal, financial and monetary institutions is so critical to the success of inflation targeting in emerging market countries. Then it discusses two emerging market countries which illustrate what it takes to make inflation targeting work well, Chile and Brazil.

In asset pricing models, the uncertainty surrounding firm fundamentals plays a central role, driving expected returns, volatility, and valuation ratios. In this paper, we extract estimates of the uncertainty embedded in earnings announcements using option prices. To do this, we take seriously the fact that the timing of earnings announcements, although not the response of equity prices, is known in advance. We develop a no-arbitrage option pricing model incorporating jumps on earnings announcement dates.
