This article develops a new framework for measuring financial and real economic linkages between countries. Using U.S. and U.K. data from 1957 to 1989, the authors find closer financial linkages after the Bretton Woods currency arrangement was abandoned and Britain suspended exchange controls. In a pairwise application to fifteen countries over a shorter period, they also find that news about future dividend growth is more highly correlated between countries than contemporaneous output measures. This suggests that there are lags in the international transmission of economic shocks and that contemporaneous output correlation may understate the magnitude of integration.

This study analyzes the effects of changes in S&P 500 index composition from January 1986 through June 1994, a period during which Standard and Poor's began its practice of preannouncing changes five days beforehand. The new announcement practice has given rise to the 'S&P game' and has altered the way stock prices react. The authors find that prices increase abnormally from the close on the announcement day to the close on the effective day. The overall increase is greater than under the old announcement policy, although part of the increase reverses after the stock is included in the index.

When the underlying price process is a one-dimensional diffusion, as well as in certain restricted stochastic volatility settings, a contingent claim's delta is bounded by the infimum and supremum of its delta at maturity. Further, if the claim's payoff is convex (concave), the claim's price is a convex (concave) function of the underlying asset's value. However, when volatility is less specialized, or when the underlying process is discontinuous or non-Markovian, a call's price can be a decreasing, concave function of the underlying price over some range, increasing with the passage of time, and decreasing in the level of interest rates.

This paper examines the role of sectors in aggregate convergence for fourteen OECD countries during 1970-87. The major finding is that manufacturing shows little evidence of either labor productivity or multifactor productivity convergence, while other sectors, especially services, are driving the aggregate convergence result. To determine the robustness of the convergence results, the paper introduces a new measure of multifactor productivity which avoids many problems inherent to traditional measures of total factor productivity when comparing productivity levels. The lack of convergence in manufacturing is robust to the method of calculating multifactor productivity. Copyright 1996 by American Economic Association.

This study examines the behavior of laboratory markets in which two uninformed marketmakers compete to trade with heterogeneously informed investors. The data provide three main results. First, marketmakers set quotes to protect against adverse selection and to control inventory. Second, when investors are 1ess well-informed, their trades are less reliable measures of their information, and marketmakers respond to those trades with greater skepticism. Third, errors in marketmakers' reactions to trades cause the time-series behavior of quotes and prices to depend on the information environment in ways beyond those captured in extant theory.

The evidence on international capital immobility is extensive, including the lack of international portfolio diversification, real interest differentials across countries, and the high correlation between domestic savings and investment. The authors develop a model with asymmetric information between countries that helps rationalize all the above observations and then examine the implications of this model for optimal domestic tax policy. Without asymmetric information, past work showed that small open economies should not impose corporate income taxes. With asymmetric information, the optimal policy instead involves government subsidies to capital imports. Some omitted factors that argue against subsidizing capital imports are explored briefly.

This paper analyzes the role of variable capital-utilization rates in propagating shocks over the business cycle. The model on which the authors' analysis is based treats variable capital-utilization rates as a form of factor-hoarding. They argue that variable capital-utilization rates are a quantitatively important source of propagation to business-cycle shocks. With this additional source of propagation, the volatility of exogenous technology shocks needed to explain the observed variability in aggregate U.S. output is significantly reduced relative to standard real-business-cycle models.

We examine whether the predictability of future returns from past returns is due to the market's underreaction to information, in particular to past earnings news. Past return and past earnings surprise each predict large drifts in future returns after controlling for the other. Market risk, size, and book-to-market effects do not explain the drifts. There is little evidence of subsequent reversals in the returns of stocks with high price and earnings momentum. Security analysts' earnings forecasts also respond sluggishly to past news, especially in the case of stocks with the worst past performance. The results suggest a market that responds only gradually to new information.
