Global turnover in foreign exchange markets averaged $1.2 trillion per day according to the most recent estimates available from the Bank for International Settlements. 1 Yet, cross-border trade of goods and services accounts for less than 5 percent of the total trading. While it is difficult to get precise estimates on hedging, roughly 20 percent of total trading is aimed at hedging against future exchange rate changes. The remaining roughly 75 percent of total turnover in global foreign exchange markets is believed to be related to short or long term exchange rate speculation. The large fraction of global turnover in currency markets that is unrelated to trade or hedging has lead economists and policy markets to the conjecture that speculation is responsible for the perceived recent increase in volatility in foreign exchange markets. Several economists, most prominently Nobel Laureate Dr. James Tobin, have advocated levying a tax (a "Tobin tax") on foreign exchange transactions to reduce volatility induced by exchange rate speculation. Recently, several European countries spearheaded by France have debated a proposed legislation to impose a tax on currency transactions. 2 However, to date, there is no strong empirical evidence that an increase in transactions costs (which would be the result of a Tobin tax) would significantly dampen volatility. On the contrary, This is the first piece of legislation in the world that would implement a Tobin-type tax. Belgium passed similar legislation in March, 2002, and several other European Union member countries have debated a Tobin tax. See www.currencytax.org.

The strength of economic theory is that it can look at the hypothetical rather than merely ex-post rationalize observed behavior. In particular, it can ask the 'what if' question of how changes in model parameters might affect efficiency and social welfare. Based on the answer, it can then suggest welfare-improving policy measures in situations in which privately optimal outcomes are socially inefficient.

Statement of Financial Accounting Standards No. 109 (SFAS No. 109) allows firms to use their discretion to set arbitrarily high valuation allowances against deferred tax assets. Firms can then later use these "hidden reserves" to manage earnings. Our evidence indicates that most banks do not record a valuation allowance to manage earnings, but rather to follow the guidelines of SFAS No. 109. However, if the bank is sufficiently well capitalized to absorb the current‐period impact on capital, then the amount of the valuation allowance increases with a bank's capital. In later years, bank managers adjust the valuation allowance to smooth earnings. The magnitude of the discretionary adjustment increases with the deviation of unadjusted earnings from the forecast or historical earnings.

Multiple-performance-measure agency models predict that optimal contracts should place greater reliance on performance measures that are more precise and more sensitive to the agent's effort. We apply these predictions to CEO retention decisions. First, we develop an agency model to motivate proxies for signal and noise in firm-level performance measures. We then document that accounting information appears to receive greater weight in turnover decisions when accounting-based measures are more precise and more sensitive. We also present evidence suggesting that market-based performance measures receive less weight in turnover decisions when accounting-based measures are more sensitive or market returns are more variable.

This article develops and estimates an on‐the‐job search model of the entry of highly skilled immigrants from the former Soviet Union into the Israeli labor market. The estimated parameters of the model, together with information on the wages of immigrants from earlier waves, imply that, on average, immigrants can expect lifetime earnings to fall short of the lifetime earnings of comparable natives by 57%. Of this figure, 14 percentage points reflect frictions associated with nonemployment and job distribution mismatch, and 43 percentage points reflect the gradual adaptation of imported schooling and experience to the local labor market.

Earnings from gold mining in Australia remained tax‐exempt for almost seven decades until January 1, 1991. In the early 1980s, rapid economic prosperity induced by escalated gold prices brought the Australian gold‐mining industry under intense political scrutiny. Using a variant of the modified Jones model, this paper provides evidence of significant downward earnings management by Australian gold‐mining firms, which is consistent with their attempts to mitigate political costs during the period from June 1985 to May 1988. In contrast, test of earnings management over a similar period in a control sample of Canadian gold‐mining firms produced insignificant results. Further, empirical results are robust to several sensitivity tests performed. During the period from June 1988 to December 1990, the Australian firms were found to have engaged in economic earnings management. This is consistent with the sample firms' incentive of maximizing economic earnings immediately prior to the introduction of income tax on gold mining. The findings of this study help to understand the impact of earnings management on the efficient resource allocation in an economy. They also contribute toward understanding the linkage between regulation of accounting for special purposes and general‐purpose financial reporting.

This paper examines whether mandatory auctions promote the efficient restructuring of distressed firms relative to a reorganization-based bankruptcy system such as Chapter 11. Under a mandatory auction system, aggressive bidding by a coalition of incumbent management and pre-bankruptcy creditors may deter outside bidders, may result in the coalition paying more than its valuation to acquire the firm, and may result in assets remaining in a lower value use. In a reorganization-based bankruptcy system, management's voluntary choice to seek an auction conveys information about the coalition's valuation, which facilitates competition. Our model shows that a reorganization-based bankruptcy system that encourages, but does not mandate auctions, can actually increase the likelihood that an outside bidder enters and the assets of the bankrupt firm are redeployed.

This paper extends the literature on executive compensation by developing and testing a principal-agent model in the context of project selection. The model's focus on executive project selection decisions highlights the multidimensional nature of executive choices that affect the value of the firm. An executive not only makes an effort choice that determines the quality of information on which to base a decision but also sets the decision criteria for selecting projects. A project selection framework is also shown to introduce endogenous uncertainty into compensation that can influence the executive's effort choice. Using an extensive data set, our empirical work supports the main hypotheses of the model, including the significance of executive rank in determining the extent of use of incentive pay in general and equity-based incentive pay in particular.
