An exploratory study of operational reasons to budget

Budgets are used widely but criticized, mainly for performance evaluation reasons. We find that organizations regard budgets as more important for planning and control than evaluation, thus proposing a rationale for their continued use irrespective of evaluation‐based criticisms. This finding is also important, because most extant budget research focuses on evaluation, suggesting a potential disconnect between budget research and practice. We also find that rolling forecasts are used in tandem with the annual budget in most organizations, and for the same reasons. This was unexpected, as coexistence suggests their adoption for different reasons.     

On the Predictability of the Stock Market Volatility: Does History Matter?

This study compares the performance of the ISD, the GARCH (1,1) , the historical volatility estimates and of two lagged trading volume measures for predicting the Swiss Stock Market Index's (SMI) volatility. The ISD has a superior daily informational content than the GARCH (1,1) estimate and retains unbiased but decreasing explanatory power over up to 20 days ahead horizons. Mean and spread daily volume measures play a significant correcting role when forecasting stock market volatility over daily and longer intervals respectively and clearly dominate the GARCH (1,1) forecasts. Their significance emphasises heterogeneous horizon traders' influence on the SMI volatility time series properties     

Forecasting the Adoption of GM Oilseed Rape: Evidence from a Discrete Choice Experiment in Germany

This paper explores farmers’ willingness to adopt genetically modified (GM) oilseed rape prior to its commercial release and estimates the ‘demand’ for the new technology. The analysis is based upon choice experiments with 202 German arable farmers. A multinomial probit estimation reveals that GM attributes such as gross margin, expected liability from cross pollination, or flexibility in returning to conventional oilseed rape significantly affect the likelihood of adoption. Neighbouring farmers’ attitudes towards GM cropping and a number of farmer and farm characteristics were also found to be significant determinants of prospective adoption. Demand simulations suggest that adoption rates are very sensitive to the profit difference between GM and non‐GM rape varieties. A monopolistic seed price would substantially reduce demand for the new technology. A monopolistic seed supplier would reap between 45% and 80% of the GM rent, and the deadweight loss of the monopoly would range between 15% and 30% of that rent. The remaining rent for farmers may be too small to outweigh possible producer price discounts resulting from the costs of segregating GM and non‐GM oilseed rape along the supply chain.

And the best estimate method is presented by contrasted with mature and advanced estimate methods as follows： the stochastic forest, stochastic gradient boosting, the support vector and artificial neuron network.     

公司治理与盈利预测的自愿披露

信息披露是上市公司与外部利益相关者沟通联系的重要渠道,其中的盈利预测又是外部利益相关者决策所需要的重要未来信息之一,因而盈利预测披露成为信息披露中被关注的焦点。同时,公司治理影响着上市公司的信息披露水平,而股权结构是决定公司治理结构与质量的基础性因素,因而公司治理可以通过股权结构的影响来作用于信息披露。     

Does foreign investor demand for information affect forecast accuracy? Evidence from the Chinese stock markets

Prior international accounting studies have examined mainly the supply side of analyst research. Specific trading rights and financial reporting systems in China provide a unique opportunity to test both demand and supply factors of analyst information. For shares traded only by less-informed foreign investors, the increased information demand may create incentives for analysts to exert greater efforts than for shares traded by local investors. This study provides evidence that analyst effort (proxied by analyst coverage) and expertise (proxied by consensus cross-analyst forecast variability) affect forecast accuracy more significantly for shares traded by foreign investors than for shares traded by local investors. Additionally, I find that the relation between analyst characteristics and relative forecast accuracy is stronger for shares traded by the foreign investors. The findings are consistent with analysts responding to demands for information by less-informed investors.

不同尺度农业预测差异及其处理

不同尺度农业预测差异是指在进行区域及其各个亚区域农业预测时，区域尺度预测结果和各个亚区域尺度预测结果之和不相等的现象。该文对此差异的产生原因进行分析后指出，历史资料的波动性是普遍存在的，历史资料拟合值的差异是导致不同尺度农业预测差异的原因。在此基础上，系统提出了以大尺度预测结果为主调整小尺度预测结果的原则。按照逐步寻优的思路，通过选择或组合应用排序修正、相关修正、增率修正、结构修正、布局修正、政策修正和趋势修正等处理方法解决不同尺度预测差异问题。
