| The difference and system generalized method-of-moments estimators, developed by Holtz-Eakin, Newey, and Rosen (1988, Econometrica 56: 1371–1395); Arellano and Bond (1991, Review of Economic Studies 58: 277–297); Arellano and Bover (1995, Journal of Econometrics 68: 29–51); and Blundell and Bond (1998, Journal of Econometrics 87: 115–143), are increasingly popular. Both are general estimators designed for situations with “small T, large N” panels, meaning few time periods and many individuals; independent variables that are not strictly exogenous, meaning they are correlated with past and possibly current realizations of the error; fixed effects; and heteroskedasticity and autocorrelation within individuals. This pedagogic article first introduces linear... |

| This paper reports on a Catchment Modelling Framework (CMF) designed to support an Australian pilot of an auction for multiple environmental outcomes EcoTender. The CMF is used to estimate multiple environmental outcomes including carbon, terrestrial biodiversity, aquatic function (water quality and quantity) and saline land area. This information was previously unavailable for application to environmental markets. This is the first time a market-based policy has been fully integrated from desk to field with a Catchment Modelling Framework for the purchase of multiple outcomes. This framework solves the unknown information problem of linking paddock scale landuse and management to catchment-scale environmental outcomes. The framework provides the... |

| The survey was designed to estimate environmental values suitable for integration into MOSAIC, a bio-economic model for catchment and farm level planning. Local residents, as well as distant rural and distant urban communities, were surveyed in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean) using choice modelling (CM). The survey aimed to find out respondents’ attitudes about, and preferences for, potential natural resource management (NRM) improvements. In total, 3,997 responses were collected from seven different locations in NSW. Fourteen split samples were established to allow for testing of incentive compatibility in CM, the impact of respondent location on values held, and scale effects. This research report describes the development... |

| The problem of determining whether quadratic programming models possess either unique or multiple optimal solutions is important for empirical analyses which use a mathematical programming framework. Policy recommendations which disregard multiple optimal solutions (where they exist) are potentially incorrect and less than efficient. This paper proposes a strategy and the associated algorithm for finding all optimal solutions to any positive semidefinite linear complementarity problem. One of the main results is that the set of complementary solutions is convex. Although not obvious, this proposition is analogous to the well-known result in linear programming which states that any convex combination of optimal solutions is itself optimal. |

| The Australian agricultural research and development (R&D) sector faces many challenges associated with the trend to increased collaborative research as promoted by the Cooperative Research Centre Program. Analysis of the results of an electronic survey of researchers involved in the sugar industry highlights economic, managerial, and sociological challenges associated with collaborative research. Researchers’ perceptions of the usefulness of a range of economic and non-economic evaluation techniques are also highlighted. It is shown that economic evaluation is appropriate for resource allocation and impact assessment purposes but is of limited value in monitoring and improving the process of collaborative research. A systems-based approach to the... |

| Numerous empirical studies in the finance field have tested many theories for firms¡¦ capital structure. Under the assumption of asymmetric information, the pecking order theory proposes the financing order for farm businesses, which implies a negative relationship between their cash flow and leverage. Meanwhile, the signaling theory suggests a farms' financing strategy, meaning high quality farms prefer to facilitate their capital rising by sending diverse signals to potential lenders. Could these capital structure theories be applied for farm businesses? This paper tests the applicability of the pecking order theory and the signaling theory for farm businesses. The results show that farm businesses not only follow the pecking order theory but also the... |
