Price Discovery without Trading: Evidence from the Nasdaq Preopening

This paper studies Nasdaq market makers' activities during the one and one-half hour preopening period. Price discovery during the preopening is conducted via price signaling as opposed to the auction used to open the NYSE or the continuous market used during trading. In the absence of trades, Nasdaq dealers use crossed and locked inside quotes to signal to other market makers which direction the price should move. Furthermore, we find evidence of price leadership among market makers that bears little resemblance to their IPO\SEO lead underwriter participation.     

Implementing Subnational Value Added Taxes on Internal Trade: The Compensating VAT (CVAT)

Thispaper describes an ingenious and elegant scheme for implementinga destination-based value added tax (VAT) on cross-border tradewithin a nation or group of nations. Sales to local purchasers(registered traders, households, and unregistered traders) wouldbe subject to the local VAT, but sales to purchasers in otherstates would be zero-rated for state VAT and subject insteadto a ``compensating value added tax' (CVAT). Credit would beallowed for tax on purchases by registered traders: for the localVAT on intrastate purchases and for the CVAT on interstate purchases.     

An Economic Analysis and Simulation of Woodfuel Management in the Sahel

This paper presents an economic framework and a computationalmethodology for assessing the evolution of woodfuel supply costsand the spatial distribution of biomass in a Sahelian woodlandsetting. Spatial data on standing stock and the costs oftransport to market are used to construct a supply curve for fuelto a fuel-consuming location. Given an exogenously specifieddemand, the model simulates, period by period, the extraction,regeneration, and transport of wood fuels. The model is appliedto evaluate the benefits and ecological impacts of scenarios forwoodland management around the city of N'Djamena, Chad.     

Price Bubbles in Laboratory Asset Markets with Constant Fundamental Values

We construct asset markets that are similar to those studied by Smith, Suchanek and Williams (Econometrica. 56, 1119–1151) in which bubbles and crashes tended to occur. The main difference between the markets studied here and those studied by Smith et al. is that in the markets studied here, the fundamental value of the asset is constant over the entire life of the asset. In four of the eight sessions reported here, we observe bubbles, which are prices considerably higher than fundamental values. The data suggest that the frequent payment of dividends is a major cause of bubble formation. The property that the fundamental value remains constant over the course of the trading horizon is not sufficient to eliminate the possibility of a bubble.     

Dynamic market impacts of generic dairy advertising

Generic advertising of fluid milk and cheese represents the principal promotional activity undertaken with the $370 million per year provided by dairy farmers and fluid milk processors. This article describes a stock-flow-feedback simulation model that includes 17 intermediate and final dairy products, short-term and long-term milk supply response and government policies that influence the impacts of generic advertising on net revenues for dairy farmers. Permanent increases in generic advertising expenditures increase net revenues for dairy farmers, with a cumulative net benefit to cost ratio of 2.8. Permanent decreases produce a larger reduction in net revenues and indicate a net benefit to cost ratio larger than 4.5. Spending a larger proportion of existing generic advertising funds on cheese rather than fluid milk would also markedly increased dairy farmer net revenues. Generic advertising increases net revenues for dairy farmers even when industry supply response and government regulation are accounted for.     

Modelling Loss of Resilience in Agroecosystems: Rangelands in Botswana

Economists have recently begun to consider the questions raised by the ecological concept of resilience – a measure of the degree to which a system can be perturbed before it switches from one stability domain to another. At a theoretical level, it has been argued that the loss of resilience in an ecological-economic system involves a change in its long-run productive potential, but no consideration has yet been given to the empirical investigation of this. This paper discusses an econometric approach to the problem, using the example of semi-arid rangelands. The long-run productive potential of the system is regarded as an unobserved state variable, change in which is irreversible or at least only slowly reversible. It is estimated by applying the extended (nonlinear) Kalman filter. The paper illustrates the approach using data from Botswana for the period 1965–1993. The maximum likelihood estimates of the parameters associated with the loss of resilience mechanism are non-zero. They indicate a small loss of resilience event at the end of the long drought in the 1980s. However, these parameters are very imprecisely estimated and are therefore statistically insignificant. We find that the sensitivity of the system to exogenous shocks varies with fluctuations in both economic and non-economic parameters. Contrary to what is usually thought to be the case, the sensitivity of the system to exogenous shocks is only weakly affected by variations in offtake prices, but is very strongly affected by variations in the cost of herd maintenance. This suggests that offtake prices may be a weak tool for controlling the size of cattle stocks and preventing a loss of resilience. On the other hand, taxes on cattle stocks or grazing fees may be very effective.     

Employment Flexibility,Dual Labour Markets,Growth, and Distribution

Many policymakers and economists have argued in favour of greater labour market flexibility as a part of structural adjustment reforms that are expected to improve economic performance. Existing post‐Keynesian‐Kaleckian (PKK) models are unable to address these issues because they assume away long‐term labour by allowing employment to be short term and adjusting freely with output. This paper introduces long‐term labour into PKK models. We develop a model that provides alternative ways of modelling labour market flexibility and suggest that when aggregate demand issues are important, an increase in employment flexibility is likely to have adverse growth and distributional impacts.     

The effects of a “no-haggle” channel on marketing strategies

As sellers increasingly turn to multi-channel retailing, the opportunity to implement different pricing policies has grown. With the advent of the internet, many traditionally bargained products such as automobiles, jewelry, watches, appliances and furniture are now being offered online at a fixed pre-determined price. We explore the strategy of simultaneously offering two pricing formats (fixed and bargained) via two different channels (online and brick and mortar) and find that in a market where there are two types of consumers—those with a high cost of haggling and others with a lower cost—a dual-pricing strategy is optimal only when there are enough high haggling-cost consumers, but not too many, and when the haggling costs between the two types of consumers are sufficiently different. We also find that it is optimal for the seller to specify a higher-than-cost minimum acceptable price as the price floor of bargaining. By doing so, the seller increases the bargained price by complementing the salesperson's bargaining ability, and also softens the internal competition between the two channels. Finally, we find that, surprisingly, the dual-pricing strategy may serve fewer customers while still being more profitable than a single price structure. The implications for consumer surplus are also explored.
