We examine the extent to which the profitability of the HML, SMB, and WML trading strategies can be linked to future GDP growth. Using a large cross-section of securities from ten developed markets, we find that the HML and SMB portfolios contain significant information about future GDP growth....

The efficient markets hypothesis implies that, in the presence of rational investors, bubbles cannot develop. We analyse the trading behaviour of a sophisticated investor, a London goldsmith bank, during the South Sea bubble in 1720. The bank believed the stock to be overvalued, yet found it...

We present a Hotelling model of price and advertising competition between prescription drugs that differ in quality/side e¤ects. Advertising results in the endogenous formation of two consumer groups: brand loyal and non-brand loyal ones. We show that advertising strategies are strategic...

A competitive stock market is embedded into a neoclassical growth economy to analyze the interplay between the acquisition of information about firms, its partial revelation through stock prices, capital allocation and income. The stock market allows investors to share their costly private...

Ratios that indicate the statistical significance of a fund’s alpha typically appraise its performance. A growing literature suggests that even in the absence of any ability to predict returns, holding options positions on the benchmark assets or trading frequently can significantly enhance...

We develop a framework to explore the asset pricing implications of simultaneous supply shocks in multiple assets in a setting with limits-to-arbitrage. The portfolio approach in Greenwood (2005) is generalized to allow for asymmetric information and therefore net positions of arbitrageurs...

In most industrialized economies, financial wealth is distributed far more unequally than income. According to Wolff (2007) more than half of the American households possess almost no productive capital while realizing about 20 percent of national income. This mismatch poses a problem for the...

We study how competition in the mutual fund industry affects stock market liquidity. We argue that mutual fund families operate as multi-product firms, jointly choosing fees, performance and number of funds and sharing common research facilities. The family-based organization generates economies...

We study the puzzle of portfolio underdiversification and proximity investment from a novel perspective, linking it to the process of urbanization. We find that urban portfolios are more focused – i.e., less diversified and more concentrated in ‘close’ stocks. We explain it in terms of the...

We exploit the restrictions of intertemporal portfolio choice in the presence of non-financial income risk to design and implement tests of hedging that use the information contained in the actual portfolio of the investor. We use a unique dataset of Swedish investors with information broken...
