This paper uses data envelopment analys is to investigate the extent to which universities in the United States have undergone productivity and efficiency changes, partly due to managerial performance, during the 2005-09 academic years. Using panel data for 133 research a nd doctoral...

The formulas of cost and allocative efficiencies of decision making units (DMUs) with positive data cannot be used for DMUs with negative data. On the other hand, these formulas are needed to analyze the productivity and performance of DMUs with negative data. To this end, this study introduces...

In the present paper an analysis of the neo-classical optimization model with linear constraints is proposed. By introducing the dual problem it is shown that the solution to the maximization problem is also a solution to the minimization problem. The purely theoretical model proposes a...

This paper examines the factors that affect inflows - outflows of capital in bond mutual funds that operated in the Greek market during the period 1997-2005. Investors in bond mutual funds do not seek for high gross returns in order to determine their investment decisions in contrast with...

This paper examines both the linear and nonlinear causal relationships between crude oil price changes and stock market returns for the United States. In particular, the study applied a battery of unit root tests to ascertain the time series properties of crude oil price changes and stock market...

Passive investment strategies basically aim to replicate an underlying benchmark. Thereby, the management usually selects a subset of stocks being employed in the optimization procedure. Apart from the optimization procedure, the stock selection approach determines the stock portfolios's...

Even though a random walk process is from a statistical point of view not predictable, some movements can be correlated with specific events concerning other variables. Then, predictable patterns may arise being dependent on this joint event. There is evidence given that equity price busts being...

Status quo bias is a systematic cognitive error which makes it difficult for individuals to make decisions independently of the currently dominant situation. This study pursues the question of whether bond market analysts are affected by status quo bias. We evaluated interest rate forecast...

We analyse diverse multifactor pricing models in order to determine if they allow to explain the variability of the returns on the personal Pension Plans in Spain between 1995 and 2003, as well as to find their sources of risks. We test the following models: APT, the one suggested by Chen, Roll...

This paper attempts to provide an economic interpretation of the factors that drive the movements of interest rates of bonds of different maturities in a continuous-time no-arbitrage term structure model for Chile. The dynamics of yields in the model are explained by two latent factors, namely...
