Modeling and analysis of future prices has been hot topic for economic analysts in recent years. Traditionally, the complex movements in the prices are usually taken as random or stochastic process. However, they may be produced by a deterministic nonlinear process. Accuracy and efficiency of economic models in the short period forecasting is strategic and crucial for business world. Nonlinear ...

Efficiency of stock markets is an essential characteristic to provide fair investment opportunities to all class of investors. It suggests that no investor shall be able to make abnormal gains using any information or by way of analysis. An understanding about the level of efficiency explores avenues for unnatural profits from the stock market. Efficient markets tend to immediately reflect all ...

Estimation of carbon contents and stocks are important for carbon sequestration, greenhouse gas emissions and national carbon balance inventories. For Denmark, we modeled the vertical distribution of soil organic carbon (SOC) and bulk density, and mapped its spatial distribution at five standard soil depth intervals (0-5, 5-15, 15-30, 30-60 and 60-100 cm) using 18 environmental variables as pre...

This paper examines the causal relationship between stock prices and macroeconomic aggregates in Iran, by applying the techniques of the long–run Granger non–causality test proposed by Toda and Yamamoto (1995). We test the causal relationships between the TEPIX Index and the three macroeconomic variables: money supply, value of trade balance, and industrial production using quarterly data for t...

The stock market is forward looking; economic indicators and important future events are factored into stock prices. According to the Efficient Market Hypothesis†, markets operate efficiently and stock prices instantly and stock prices instantly reflect all information available. However, inefficiencies in the stock market exist due to the behaviors and expectations of investors. Stock prices m...

This study is concerned with the aggregation of information in stock index cash and futures markets. The efficient price discovery is analyzed with reference to the error correction representation and to the common trend representation of cointegrated variables. The empirical evidence is based on three month of intraday data on the French CAC 40 index. The results indicate that deviations from ...

Soil carbon and nitrogen contents play an important role in sustaining soil physical and chemical quality and help to have healthy environments. The continues conversion of rangelands to arable lands has the potential to change carbon and nitrogen sequestration. In this study to evaluate the effects of land use change on soil organic carbon and nitrogen stock, forty samples collected from north...

We develop a dynamic model to investigate the optimal time paths of carbon emissions, sequestration, and the carbon stock. We show that carbon sinks should be utilized as early as possible, and carbon flow into sinks should last until the atmospheric carbon concentration is stabilized. We rule out any cyclical patterns of carbon sequestration and release. We propose and assess three mechanisms ...

The present study is being contemplated with the objective of studying the degree of stock market integration. In this study, month-wise average prices of BSE-Sensex, NYSE, NASDAQ, S&P500, HangSeng, Nikkei225, SSE Composite index and FTSE100 have been selected. Multiple Correlations has been computed for the select stock market indices. Statistical Significance of the correlation has been teste...
