ECONOMIC IMPACTS OF THE FINANCIAL CRISIS ON THE KOREAN FARM AND NON-FARM SECTORS

The objective of this study is to construct a macroeconomic model emphasizing agriculture and analyze the economic impacts of the financial crisis on the Korean farm and non-farm sectors. The simulation results show that financial shocks have great impacts on general economy and change the resource allocation within and between farm and non-farm sectors.Financial Crisis, Macroeconomic Model, Agricultural Finance, Research Methods/ Statistical Methods,

Endoscopic Versus Traditional Craniofacial Resection for Patients with Sinonasal Tumors Involving the Anterior Skull Base

ObjectivesWith the advent of microdebriders and image guidance systems, endoscope-assisted surgery is now more widely used for the treatment of tumors involving the base of the skull. The aim of this study was to analyze the clinical features of tumors involving the anterior skull base and to evaluate the treatment outcomes according to the surgical approach, which included the traditional craniofacial resection (TCFR) and the endoscopic craniofacial resection with craniotomy (ECFR).MethodsForty-six patients who underwent craniofacial resection from 1989 through 2006 at Seoul National University Hospital and Seoul National University Bundang Hospital were included in this study. Demographics, histology, surgical management, surgical outcomes, complications, and morbidity were analyzed.ResultsThe number of malignant and benign lesions was 40 and 6 cases respectively. The most common diagnosis was olfactory neuroblastoma occurring in 41% of the cases followed by squamous cell carcinoma and malignant melanoma. Thirty-six patients underwent TCFR, while ECFR was performed with or without adjunctive chemotherapy or radiotherapy in 10 patients. The overall five-year survival rate for patients with malignant tumors of the anterior skull base was 47.4%. Out of 19 patients with olfactory neuroblastomas, 10 patients had TCFR and six among them died of their disease. Nine patients underwent ECFR, and none of them died of their disease. The ECFR group had lower morbidity and cosmetic deformity than did the TCFR group.ConclusionThe ECFR may be considered as an alternative option for the treatment of selected tumors with anterior skull base invasion. This approach offers the advantages of avoiding facial incisions with comparable treatment results

Investment and expectations in the U.S. farm sector

Typescript (photocopy).The objective of this study was to analyze the interrelationship between expectations patterns and investment behavior of producers in the U.S. farm sector. A major problem confronting U.S. farm sector is overinvestment and the asset fixity of farm physical assets. An understanding of farmer's investment behavior for capital goods is needed by both farm financial intermediaries to evaluate potential loan demand and by manufactures of farm capital inputs to formulate production and marketing strategy. A review of previous studies reveals one or more of the following major shortcomings: (1) no explicit treatment of expectations on the empirical application of investment theory, (2) a lack of studies addressing the effects of farm program policy on the investment in the U.S. farm sector, (3) no justification of the choice of expectations in the agricultural economic studies. The neoclassical investment model is chosen over other approaches in this study because of direct linkages it enables us to establish between fanners' investment decision and government policies, including monetary policy, fiscal policy, and farm program policy. To incorporate farm policy programs on aggregate investment equations, the expected implicit revenue in crop production was developed. To measure the expected implicit revenue, expected price and expected yield for each crop was estimated under alternative expectations specifications. The five major crops considered in this study are wheat, com, sorghum, cotton, and soybeans. Eight expectations specifications for price and yield of each crop are as follows: (1) the naive expectations, (2) the extrapolative expectations, (3) the adaptive expectations, (4) the ARIMA expectations, (5) VAR expectations, (6) the augmented adaptive expectations, (7) the error correction expectations, and (8) the expectations derived from a general equilibrium model emphasizing agriculture. Net investment equations for equipment and structures as a function of expected implicit revenue and expected implicit rental price of capital were estimated. Once the net investment equations were estimated, the performance of the alternative expectations hypothesized in farm sector investment equations for equipment and structures was validated using multi-dimensional criteria. Finally, the estimated equations for the alternative expectations patterns were endogenized into the AG-GEM model to examine the extent to which each hypothesis altered the impact of two topics of current interest: the impact of no chemical use and the impact of high deficits
