BUNDLING IN AUCTIONS WITH NON‐LINEAR VALUATIONS*

We examine when a revenue‐maximising auctioneer prefers to auction a homogenous product in one bundle (a single‐object auction) than to sell the item in two or more shares. When the items are super‐additive the auctioneer always prefers a single‐object auction. When the product valuations are sub‐additive, the auctioneer is more likely to choose a share auction when there are a large number of potential bidders. When there are a small number of bidders the auctioneer will tend to prefer a single‐object auction.     

Fiscal policies and the institution of a tax state in Anglo‐Saxon England within a comparative context1

This article begins by noting that military revolutions and civil wars in early modern Europe provide an unduly narrow framework for understanding the transition from a domain to a tax state. Taking Anglo‐Saxon England as a case study, it is suggested that political restrictions led to the establishment of direct and indirect taxation, thereby providing rulers with revenues which surpassed those from domain resources. The main section of the article uses sources from coinage and wills to poetry and letters in order to give a general idea of the chronological development of a medieval tax state. This analysis challenges the views of the new fiscal historians, who argue that a collapse in a medieval domain state acts as the precondition for the emergence of a tax state. Instead, this article suggests that new policies arose because of the need of Anglo‐Saxon kings and their advisers to take account of the requirements of ecclesiastical authorities, as well as a heavy revenue imperative, in paying for resistance against the Vikings. The article ends with a discussion of the comparative applications of the contexts and catalysts which lead to the adoption of pioneering fiscal policies.     

MACROECONOMIC POLICY REFORMS AND PRODUCTIVITY GROWTH IN AFRICAN AGRICULTURE

This article employs a two‐stage procedure to investigate the impact of macroeconomic policy reforms on the agricultural productivity growth of 33 African countries from 1981 to 2001. In the first stage, we measure agricultural productivity using a nonparametric Malmquist productivity index. In the second stage, we build a generalized method of moments (GMM) model with a measure of structural adjustment program (SAP) intensity as a key instrument for macroeconomic policy reforms. We also control for the effects of globalization, civil violence, level of development of physical and financial infrastructure, and other economic variables as well as natural resource factors that directly affect agricultural productivity. Our results indicate a strong positive correlation between the extent of SAP intensity and agricultural productivity, suggesting that the macroeconomic policy reforms improved agricultural productivity growth in the sample countries.

Tax-Induced Trading: The Effect of the 1986 Tax Reform Act on Stock Market Activity

The end of favorable tax treatment for long-term capital gains caused investors to reassess traditional tax-induced trading strategies. This study compares trading behavior in December 1986 and January 1987 with previous years. Our results indicate that these tax code changes had a powerful effect on trading behavior. Relative trading volume was considerably higher in December 1986 for long-term winners but not significantly lower for long-term losers. Results also indicate altered trading patterns based on short-term gains in December 1986 and for long-term winners in January 1987.     

Financial Returns and Price Determinants in the Australian Art Market, 1973–2003*

In this study, 37 605 paintings by 60 well-known Australian artists sold at auction over the period 1973–2003 are used to construct a hedonic price index. The attributes included in the hedonic regression model include the name and living status of the artist, the size and medium of the painting and the auction house and year in which the painting was sold. The resulting index indicates that returns on Australian fine-art averaged 7 per cent over the period with a standard deviation of 16 per cent. The hedonic regression model also captures the willingness to pay for perceived attributes in the artwork, and this shows that works by McCubbin, Gascoigne, Thomas and Preston and other artists deceased at the time of auction, works executed in oils or acrylic, and those auctioned by Sotheby's or Christie's are associated with higher prices.     

Incentives,Monitoring, and Employee Stock Ownership Plans: New Evidence and Interpretations

This paper reviews the theory and evidence for agency theory‐based explanations for employee stock ownership plans found in the financial participation literature. The UK Workplace Employee Relations Survey 1998 is used to test whether share plans substitute for direct monitoring and individual incentives. Contrary to some predictions in the literature, individual incentives are found to be complements of share plans, while other measures of monitoring costs provide mixed results. However, it is found that monitoring costs and a wide range of performance targets explain the conjunction of stock plans and individual incentives. It is suggested that share plans are used to mitigate dysfunctional effects of individual incentives by engendering cooperation and trust, and by broadening the range and time frame of desired performance outcomes.
