Bundling and Menus of Two-Part Tariffs

Inducing self-selection among different segments of consumers is an important issue in pricing. Some firms induce self-selection by offering a menu of two-part tariffs (e.g., different rate plans) and letting consumers select the tariff and quantity they prefer. Other firms induce self-selection by offering a menu of price-quantity bundles (e.g., different package sizes) and letting consumers select only from among these bundles. We show that bundling is more profitable absent cost considerations. Social welfare may be higher or lower with bundling.     

'High-performance' Management Practices, Working Hours and Work–Life Balance

The effects of selected high‐performance practices and working hours on work–life balance are analysed with data from national surveys of British employees in 1992 and 2000. Alongside long hours, which are a constant source of negative job‐to‐home spillover, certain ‘high‐performance’ practices have become more strongly related to negative spillover during this period. Surprisingly, dual‐earner couples are not especially liable to spillover — if anything, less so than single‐earner couples. Additionally, the presence of young children has become less important over time. Overall, the results suggest a conflict between high‐performance practices and work‐life balance policies.     

Restricted electricity use among poor urban households

For a variety of reasons, this article argues, electricity must be seen by policy‐makers in South Africa not as the sole provider of all future household energy needs, but rather as one component of an energy mix which includes such ‘transitional’ fuels as coal, gas and paraffin. The reasons for this are that electricity is expensive for poor households; it is subject to power failures and disconnections for non‐payment; the poor find it difficult to monitor and to control their consumption; appliances are expensive and several are required to make best use of electricity; people prefer other fuels because they are familiar and have strong personal and cultural associations, and because Eskom is not trusted owing to its past ties to illegitimate local authorities and misunderstanding of electricity and how its use is monitored and charged for. Further, it is mistaken to equate ‘development’ with total electrification: most developed countries have fuel mixes which include gas and coal, particularly for cooking and heating. Accepting an affordable fuel mix for the poor in particular would focus attention on the problems currently associated with paraffin, gas and coal, namely fires, poisoning and air pollution.

Regulatory Monitoring and the Impact of Bank Holding Company Dividend Changes on Equity Returns

This paper examines the impact of announcements of dividend changes by bank holding companies (BHCs) on equity returns. Many empirical studies of dividend behavior reveal positive market responses to dividend increases, which have been interpreted as confirmation of the signalling theory of dividend behavior. These studies typically focus on “large” changes, however. We argue that BHCs allow for a stronger test of signalling theory because regulatory monitors, in effect, “certify” dividend signals. Consequently, even “small” dividend increases should result in positive abnormal equity returns. Using the event study methodology, our results generally confirm this hypothesis for a sample covering the period 1973–1987.     

COORDINATING PRODUCTION AND DISPOSAL OF COMMODITY STOCKPILES WITH APPLICATION TO AUSTRALIA'S WOOL INDUSTRY

Following the dismantling of a price-support program, a central bureaucracy is left with a commodity stockpile to dispose. It happened with wheat and feed grains in the U.S. in 1986 and wool in Australia in 1991. It soon may happen in Europe with grains, manufactured dairy products and other commodities which have supported prices. Obvious policies include privatising the stockpile, disposing of the stockpile by a central bureaucracy and quarantining the stockpile from the market. Each policy imposes constraints on disposal based, perhaps, on judgments of political acceptability to producers and government. In this article, optimal rules for production and disposal are derived and solved and a new policy is proposed. Then the model is applied to the disposal of Australia's wool stockpile. Results show that centralised disposal will almost always be preferred to privatisation of the stockpile. Centralised disposal is also preferred to quarantining the stockpile if interest rates are high, but quarantining is preferred if interest rates are low. Centralised disposal and quarantining are not optimal, however. Optimal production and disposal combines the efficiency of privatisation with the market power of centralised disposal. To achieve this, the property rights to the stockpile can be redefined using payment-in-kind certificates and individual transferable entitlements. The payment-in-kind certificates assign ownership of the stockpile to individual producers who then make both production and disposal decisions. The individual transferable entitlements allow the industry to produce efficiently and extend market power from the central bureaucracy to producers. For the Australian wool stockpile, optimal production and disposal would benefit the industry by an estimated $2.7 billion.
