The finance industry has grown, financial markets have become more liquid, information technology has undergone a revolution. But have market prices become more informative? We derive a welfare-based measure of price informativeness: the predicted variation of future cash flows from current...

International capital flows, while potentially beneficial, are said to increase a country's vulnerability to crisis - especially if they are skewed to non-FDI types. This paper studies whether the volume and composition of capital flows affect the degree of credit crunch faced by a country's...

This paper investigates the impact on bank stock prices of emerging market currency crises and bailouts. The stock market distinguishes between banks with exposure to a crisis country and other banks. In general, banks with exposures to a crisis country are affected adversely by currency events...

Volatility tests are an alternative to regression tests for evaluating the joint null hypothesis of market efficiency and risk neutrality. Acomparison of the power of the two kinds of tests depends on what the alternative hypothesis is taken to be. By considering tests based on conditional...

In a model where a variable Y[sub t] is proportional to the present value, with constant discount rate, of expected future values of a variable y[sub t] the "spread" S[sub t]= Y[sub t] - [theta sub t] will be stationary for some [theta] whether or not y[sub t]must be differenced to induce...

The behavioral finance literature cites the frozen concentrated orange juice (FCOJ) futures market as a prominent example of the failure of prices to reflect fundamentals. This paper reexamines the relation between FCOJ futures returns and fundamentals, focusing primarily on temperature. We show...

We analyze cross-sectional and time series information from forty-seven equity markets around the world, to consider whether short-sales restrictions affect the efficiency of the market, and the distributional characteristics of returns to individual stocks and market indices. Using the approach...

We investigate whether stock markets efficiently price risks brought on or exacerbated by climate change. We focus on drought, the most damaging natural disaster for crops and food-company cash flows. We show that prolonged drought in a country, measured by the Palmer Drought Severity Index...

Large institutional investors own an increasing share of equity markets. We conjecture that a financial market in which large institutions dominate operates differently than a market populated by smaller independent investors. To support this view, we show that funds within the same family...
