Floor trading and screen trading : distinctions for practitioners

The creation of an electronic limit order book is discussed as the basis for distinguishing between the floor trading and screen trading of derivative instruments. Distinguishing between FTP and ETP in terms of market transparency allows investors to contemplate the trade-off between the 2 platforms. Distinguishing between FTP and ETP in terms of memory preservation allows practitioners to contemplate the different experiences when analyzing floor data and screen data. A comparable set of floor and screen data is used to examine the impact on the trading dynamics and price discovery of LIFFE's FTSE 100 index futures market when trading is automated on LIFFE CONNECT. The dynamics in the quote change equation is shortened when moving from the floor to screen sample. Using the model's measure of trade informativeness, it is found that in 4 out of 5 daily sub-samples, screen trades are more than twice as informative as floor trades. Variability within a system of equations is explained more by order size history than trade size history.

Measuring the summary informativeness of orders and trades

Improved preservation of order flow history from the automation of derivative trading platforms suggests that traders are potentially learning from the recent history of both order and trade parameters. Consequently, a model to measure price discovery should encapsulate the dynamic interaction between the price-size coordinates of orders and trades. The Hasbrouck (1991) model is extended to measure the summary informativeness of order size and trade size. The two models are used to test for price discovery improvements in the FTSE 100 index futures market from order flow consolidation post deletion of its E-mini counterpart. The informativeness of trades has declined sharply, while the informativeness of orders has risen significantly in the post deletion sample.

The volume and volatility relation in the Australian stock market

The thesis studies the volume-volatility relation in the Australian Securities Market. It is concluded that the number of trades is the most important variable driving realized volatility. The average trade size is significant but its explanatory power is only trivial. Order imbalance does not drive volatility in the Australian market.

Investment in sensory structures, testis size, and wing coloration in males of a diurnal moth species: trade-offs or correlated growth?

For dioecious animals, reproductive success typically involves an exchange between the sexes of signals that provide information about mate location and quality. Typically, the elaborate, secondary sexual ornaments of males signal their quality, while females may signal their location and receptivity. In theory, the receptor structures that receive the latter signals may also become elaborate or enlarged in a way that ultimately functions to enhance mating success through improved mate location. The large, elaborate antennae of many male moths are one such sensory structure, and eye size may also be important in diurnal moths. Investment in these traits may be costly, resulting in trade-offs among different traits associated with mate location. For polyandrous species, such trade-offs may also include traits associated with paternity success, such as larger testes. Conversely, we would not expect this to be the case for monandrous species, where sperm competition is unlikely. We investigated these ideas by evaluating the relationship between investment in sensory structures (antennae, eye), testis, and a putative warning signal (orange hindwing patch) in field-caught males of the monandrous diurnal painted apple moth Teia anartoides (Lepidoptera: Lymantriidae) in southeastern Australia. As predicted for a monandrous species, we found no evidence that male moths with larger sensory structures had reduced investment in testis size. However, contrary to expectation, investment in sensory structures was correlated: males with relatively larger antennae also had relatively larger eyes. Intriguingly, also, the size of male orange hindwing patches was positively correlated with testis size.

The role of endowments, technology and size in international trade: new evidence from product-level data

Using product-level trade data, we empirically investigate the export patterns of more than 150 countries in their exports to the USA, Brazil, India, and Japan. We document strong evidence that exporters specialize according to their relative factor endowments, technology, and economic size. More developed, capital abundant countries are found to export products of higher unit values and a wider range of products to developed, emerging and developing markets. More developed, economically larger, and technologically advanced countries are also the major exporters of new products, spanninga wide range of product categories with high unit values. Our findings provide important insights into the macro phenomenon that a large proportion of the global trade takes place among developed economies, and that the latter are also major exporters to developing markets.

Players, clubs, events and the Trade Practices Act : a primer for sporting clubs

The Trade Practices Act (TPA) has had an enormous impact on how corporations in Australia may conduct their business. In relation to sporting clubs, it limits the freedom of clubs to deal with players, each other and the public. While previously many clubs may have escaped the ambit of the TPA because they were not “corporations”, state equivalent Fair Trading legislation and the introduction of the national competition policy in 1995 have effectively expanded the scope of consumer and competition regulation to include individuals and associations. Consequently, an understanding of the nature and scope of trade practices regulation is now important for any sporting organisation—regardless of size or structure. This paper identifies the legislative provisions most likely to impact upon sporting clubs and examines some possible circumstances in which clubs might find themselves exposed to liability.

Revisiting capital structure theory : a test of pecking order and static order trade-of model from Malaysian capital market

This study revisits the capital structure theory and test Pecking Order Hypothesis (POH) and Static Order Trade-off theory (STOT) using Malaysian Listed firms over a period from 1999 to 2002. The evidence from pecking order model suggests that the internal fund deficiency is the most important determinant that possibly explains the issuance of new debt in Malaysian capital market despite the lower predicting power.  While static trade off-model is not fit to explain the issuance of new debt issue in Malaysian capital market. This is an interesting findings that confirm the fact that Malaysian firms do not too much care about tax-shield benefit derive from employ both debt and non-debt tax-shield. The finn's size, which is used to neutralize the size effect, appears to provide some explanation for the variation in its capital structure policy choice; however asset structure and growth no evidence of static-order-trade-off is observed in Malaysian capital market.

Endogenous transportation technology in a cournot differential game with intraindustry trade

We investigate a dynamic Cournot duopoly with intraindustry trade, where firms invest in R&D to reduce the level of iceberg transportation costs. We adopt both open-loop and closed-loop equilibrium concepts, showing that a unique (saddle point) steady state exists in both cases. In the open-loop model, optimal investments and the resulting efficiency of transportation technology are independent of the relative size of the two countries. On the contrary, in the closed-loop case firms’ R&D incentives are driven by the relative size of the two countries. Policy implications are also evaluated.

Behavioural trade-offs between growth and mortality explain evolution of submaximal growth rates

1. The importance of body size and growth rate in ecological interactions is widely recognized, and both are frequently used as surrogates for fitness. However, if there are significant costs associated with rapid growth rates then its fitness benefits may be questioned.

2. In replicated whole-lake experiments, we show that a domestic strain of rainbow trout (artificially selected for maximum intrinsic growth rate) use productive but risky habitats more than wild trout. Consequently, domestic trout grow faster in all situations, experience greater survival in the absence of predators, but have lower survival in the presence of predators. Therefore, rapid growth rates are selected against due to increased foraging effort (or conversely, lower antipredator behaviour) that increases vulnerability to predators. In other words, there is a behaviourally mediated trade-off between growth and mortality rates.

3. Whereas rapid growth is beneficial in many ecological interactions, our results show the mortality costs of achieving it are large in the presence of predators, which can help explain the absence of an average phenotype with maximized growth rates in nature.

Cross-border travellers and parallel trade: implications for Asian economies

This paper explores the impact of parallel trade in an export market by cross-border travellers on welfare of the home country in a model with heterogeneous consumers' perceptions. We show that such parallel trade when it is organised trading always hurts the home-country welfare. However, when parallel trade is unorganised trading, it might benefit the home-country welfare provided that the size of the export market is relatively small. Along these lines, we suggest optimal policy responses in the home country to parallel trade by cross-border travellers. The results of the paper yield insightful policy implications for Asian economies.

A method for comprehensively assessing economic trade-offs of new irrigation developments

To meet the anticipated increase in global demand for food and fibre products, large areas of land around the world are being cleared and infrastructure constructed to enable irrigation, referred to herein as ‘greenfield irrigation’. One of the challenges in assessing the profitability of a greenfield irrigation development is understanding the impact of variability in climate and water availability and the trade-offs with scheme size, cost and the sensitivity of crop yield to water stress. For example, is it more profitable to irrigate a small area of land most years or a large area once every few years? And, is it more profitable to partially or fully water the crop? This paper presents a new method for efficiently linking a river system model and an agricultural production model to explore the financial trade-offs of different management choices, thereby enabling the optimal scheme area and most appropriate level of farmer risk to be identified. The method is demonstrated for a hypothetical but plausible greenfield irrigation development based around a large dam in the Flinders catchment, northern Australia. It was found that a dam and irrigation development paid for and operated by the same entity is not, under the conditions examined in this analysis, economically sustainable. The method could also be used to explore the impact of different management strategies on the agricultural production and profitability of existing irrigation schemes within a whole of river system context.
