We use firm-level panel data to explore the extent to which fixed investment responds to tax reforms in 14 OECD countries. Previous studies have often found that investment does not respond to changes in the marginal cost of investment. We identify some of the factors responsible for this finding, and employ an estimation procedure that sidesteps the most important of them. In so doing, we find evidence of statistically and economically significant investment responses to tax changes in 12 of the 14 countries.

The financial policy highly leveraged firms (HLFs) commonly follow implies uncertain leverage. Explicit allowance for this characteristic leads to two complementary pricing models. A recursive formula for the value of HLF follows from applying the adjusted present value (APV) approach to uncertain tax shields. This formula is used to evaluate the robustness of the simple APV rule and other valuation approaches used in practice.

We examine conditions under which "Veblen effects" arise from the desire to achieve social status by signaling wealth through conspicuous consumption. While Veblen effects cannot ordinarily arise when preferences satisfy a "single-crossing property," they may emerge when this property fails. In that case, "budget" brands are priced at marginal cost, while "luxury" brands, though not intrinsically superior, are sold at higher prices to consumers seeking to advertise wealth.

We develop lower and upper bounds on the prices of American call and put options written on a dividend-paying asset. We provide two option price approximations one based on the lower bound (termed LBA) and one based on both bounds (termed LUBA). The LUBA approximation has an average accuracy comparable to a l,000-step binomial tree. We introduce a modification of the binomial method (termed BBSR) that is very simple to implement and performs remarkably well. We also conduct a careful large-scale evaluation of many recent methods for computing American option prices.

Simulation has proved to be a valuable tool for estimating security prices for which simple closed form solutions do not exist. In this paper we present two direct methods, a pathwise method and a likelihood ratio method, for estimating derivatives of security prices using simulation. With the direct methods, the information from a single simulation can be used to estimate multiple derivatives along with a security's price. The main advantage of the direct methods over re-simulation is increased computational speed.

A study was conducted to interpret the price-earnings ratio (P/E) and the market-to-book ratio (P/B) and describe their articulation. It also aimed to explain the role of book rate-of-return on equity in determining the ratios and the relation between them. The P/E ratio signifies future growth in earnings positively related to expected future return on equity and negatively related to current return on equity. On the other hand, the P/B ratio indicates only expected future return on equity.

Theoretical work on financing costs under asymmetric information has linked shifts in firms' internal funds and investment spending, holding constant investment opportunities. An impediment to convincing tests of these models is the lack of firm-level data on the relative cost of internal and external funds. We use a tax experiment, the surtax on undistributed profits in the 1930s, to identify firms' relative cost of internal and external funds by calculating surtax margins.

This paper examines CEO pay in the banking industry and the effect of deregulating the market for corporate control. Using panel data on 147 banks over the 1980s, we find higher levels of pay in competitive corporate control markets, i.e., those in which interstate banking is permitted. We also find a stronger pay-performance relation in deregulated interstate banking markets. Finally, CEO turnover increases substantially after deregulation.
