Social media-based forecasting has received significant attention from academia and industries in recent years. With a focus on Twitter, this paper investigates whether sentiments of the tweets regarding the 7 largest US financial service companies (in U.S. dollars) are related to the stock price changes of these companies. The authors’ findings indicate, in the financial services context, nega...

Ageing typically leads to various memory deficits which results in older adults' tendency to remember more general information and rely on gist memory. The current study examined if younger and older adults could remember which of two comparable grocery items (e.g., two similar but different jams) was paired with a lower price (the "better buy"). Participants studied lists of grocery items and ...

A static, generalized input± output framework for calculating simple multipliers is presented for Australian data. In this framework, capital investment and imports are internalized into domestic inter-industrial intermediate demand, non-square matrices are introduced in order to enable the inclusion of ® ner detail commodity data, and matrices in both monetary and physical units are employed. ...

This paper empirically determines why, during the 1990s, inflation in Canada was consistently more stable than predicted by the fixed-coefficients Phillips curve. A time-varying-coefficient model, where all the parameters adjust simultaneously, shows that the behaviour of expectations was probably a major contributing factor. A decrease in the value of the coefficient on the first difference of...

Intraday currency futures prices react to both surprises in the federal funds target rate (the target factor) and surprises in the anticipated future direction of Federal Reserve monetary policy (the path factor) in similar magnitude, and the reaction is short-lived. Dollar-denominated currency futures prices drop significantly in response to positive surprises (i.e., unexpected increases) in t...

This study analyzes the potential impacts of expanded ethanol production on southern agriculture. Results of regression analysis suggest that acreage planted for field crops (corn, cotton, soybeans, and wheat) is inelastic with respect to relative prices. The results provide statistical evidence of potential significant acreage shifts favoring corn over cotton, soybeans, and wheat. Simulations ...

There are various causes for inflation in macroeconomics. One of the important channels of experiencing inflation is through the international economy caused by external shocks. In this context, the impact of exchange rate volatilities on domestic prices known as Exchange Rate Pass-Through (ERPT) plays a vital role. The present paper deals with the impact of Exchange Rate Pass-Through on inflat...

Organizations frequently consider offshore systems development in the belief that projects can be completed for lower cost. While prices quoted by offshore vendors are often very appealing when compared with domestic vendors, there are additional risks that must be considered when looking to offshore systems development. These risks typically take the form of intangible and indirect project cos...

This paper deals with convergence model of interest rates, which explains the evolution of interest rate in connection with the adoption of Euro currency. Its dynamics is described by two stochastic differential equations – the domestic and the European short rate. Bond prices are then solutions to partial differential equations. For the special case with constant volatilities closed form solut...
