Theories of language production need to account for how speakers produce prosodic structure. Very few models have addressed the role of prosodic phrasing in speech planning, and little experimental work examining this question has been conducted so far. Four studies designed to investigate the effect of phrase length and prosodic phrasing on speech planning are presented. The first experiment e...

Seemingly unrelated regressions are statistical regression models based on the Gaussian distribution. They are popular in econometrics but also arise in graphical modeling of multivariate dependencies. In maximum likelihood estimation, the parameters of the model are estimated by maximizing the likelihood function, which maps the parameters to the likelihood of observing the given data. By tran...

The study measures farm credit risk by using farm records collected by Farm Business Farm Management (FBFM) during the period 1995-2004. The study addresses the following questions: 1) whether farm " s financial position is fully described by the structure model, 2) what are the determinants of farm capital structure under the structure model, 3) how to estimate and test farm asset correlation,...

Private passenger automobile insurance companies employ a range of strategies and tactics to achieve their growth and profitability objectives. Gains and losses in market share among insurers suggest a fair degree of rivalrous behavior; however, previous econometric analyses have not adequately addressed the sources of firm-level advantages. Although prior studies have tested hypotheses about d...

Jointly produced renewable resources, such as fish, have been extensively studied in the literature on multiproduct firms. However, relatively little empirical work has been done on jointly produced non-renewable resources such as metals. This difference is key because theoretical Hotelling-style models have shown that non-renewable resource producers faced with fixed capacity constraints and h...

Two procedures that guarantee the property of additivity among the components of tree biomass and total tree biomass utilizing nonlinear functions are developed. Procedure 1 is a simple combination approach, and procedure ‘2. is based on nonlinear joint-generalized regression (nonlinear seemingly unrelated regressions) with parameter restrictions. Statistical theory is given for construction of...

Stand conditions influence the partitioning of biomass to stem, foliage, branch, and root components. Using data from 4 to 6-year old loblolly pine (Pinus taeda L.) trees grown in a miniature-scale spacing trial, this study determined the effect of initial planting density on the biomass partitioning of loblolly pine. An analysis of covariance concluded that density did not have a significant e...

This study considers the effect of an industry's network topology on its systemic risk contribution to the stock market using data from the CSI 300 two-tier industry indices from the Chinese stock market. We first measure industry's conditional-value-at-risk (CoVaR) and the systemic risk contribution (ΔCoVaR) using the fitted time-varying t-copula function. The network of the stock industry is ...

In many studies the assumption is made that traders only encounter one type of price risk. In reality, however, traders are exposed to multiple price risks, and often have several relevant derivative instruments available with which to hedge price uncertainty. In this study, commodity, foreign exchange, and freight futures contracts are analyzed for their effectiveness in reducing price uncerta...

This paper examines the nature of interregional competition and complementarity in Indonesia. The analysis is important for the island country given the heterogeneity of the regional economies and will provide insights into the structure of economic interactions that should prove useful for policy-makers considering alternative decentralization schemes. Covering the 1975-1999 period, the analys...
