The Wakool wartime rice–growing project and its impact on regional development

This study forms part of a larger project which investigates how political, bureaucratic, and economic forces influenced the historical development of the Wakool Irrigation District and the Tullakool Irrigation Area in south–west New South Wales between 1930 and 1995. The article itself focusses on the NSW government’s Second World War rice–growing project at Wakool both as a unique exercise in itself and also to explore some historical reasons behind an important policy shift and associated fundamental changes in subsequent land– use, settlement patterns, and environmental amenity in the area.     

Price dynamics in limit order markets

This article presents a one-tick dynamic model of a limit ordermarket. Agents choose to submit a limit order or a market orderdepending on the state of the limit order book. Each traderknows that her order will affect the order placement strategiesof those who follow and the execution probability of her limitorder is endogenous. All traders take this into account which,in equilibrium, generates systematic patterns in transactionprices and order placement strategies even with no asymmetricinformation.     

On the solution of a stochastic optimal growth model

This note discusses a stochastic optimal growth model in which the optimal paths can be obtained by a simple direct argument. The structural characteristics of the model are the infinite horizon, the form of the instantaneous utility function, and uncertainty as a Wiener process in a linear production constraint. The note explains that, for optimality, at each point in time a formally identical problem must be solved. This implies that the optimal saving ratio must be constant.A proof, employing the rules of stochastic calculus, that the ensuing paths are the unique globally optimal paths is also given.We are very grateful to two referees of this journal for their invaluable comments and suggestions.     

Strategic Purity and Efficiency in the Motor Carrier Industry: A Multiyear Panel Investigation

Two questions facing motor carrier managers are (1) whether carriers should specialize in providing full truckload (TL) or less‐than‐truckload (LTL) services vis‐à‐vis offering mix of both and (2) whether this decision is contingent on carrier size. Yet, the literature provides little guidance because research to date has offered contradictory theoretical predictions and inconsistent empirical findings. Drawing on the theory of strategic purity and information processing theory, we explain why service specialization is likely to increase carriers' technical efficiency and why size will have a more pronounced effect on technical efficiency for carriers specializing in LTL services versus TL services. To test our theory, we assemble a panel data set from archival government sources regarding general freight motor carriers' provision of LTL and TL services. We measure carriers' technical efficiency using data envelopment analysis and test our hypotheses by fitting a series of panel data mixed‐effects models. Our results indicate that carriers are most technically efficient when they specialize in one service type. We also find that size positively affects technical efficiency but only for carriers specializing in LTL services; no returns to scale with regard to technical efficiency exist for carriers specializing in TL services.

Chinese Investment in Latin American Resources

China's need for vast amounts of minerals to sustain its high economic growth rate has increasingly turned Chinese investors towards Latin America.This demand has propelled China into third place among Latin American investors,directing over $15 billion (about 9
