A competitive firm which chooses the timing of investment and optimal volume of debt is considered. The price of the firm’s output follows the geometric Brownian motion or more general jump-diffusion processes, and the firm takes an arbitrage free borrowing rate as given. The optimal timing of investment and volume of debt is computed, and it is shown that if the borrowing rate is close to the ...

Business confidence is a well-known leading indicator of future output. Whether it has information about future investment is, however, unclear. We determine how informative business confidence is for investment growth independently of other variables using US business confidence survey data for 1955Q1–2016Q4. Our main findings are: (i) business confidence leads US business investment growth by...

In this study, a three–layer artificial neural network (ANN) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. A total of 455 data points were collected from 13 data sources to develop the ANN model. Superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of ...

The present study conducted based on secondary assess the health of Hester Biosciences Limited. focuses investigating solvency ratio, profitability ratio return also explores companys efficiency us...

t Wilkie's stochastic investment model and its variants have been increasingly applied by actuaries around the world to actuarial modeling and simulation. This paper performs time series outlier analysis on retail price inflation, which is the driving force of Wilkie's composite model. The data come from four developed countries: the United Kingdom, the United States, Canada, and Australia. The...

The cost of public investment is not the value of public capital. Unlike with private investors, there is no plausible behavioral model in which every dollar that the public sector spends as “investment” creates capital in an economic sense. While this simple analytic point is obvious, it has so far been uniformly ignored in the empirical literature on economic growth which uses, at best, cumul...

economic growth is the most important purpose of developing countries. each country can improve social welfare and access to international markets by increasing production potential. production can increase by two ways: the first one, using more inputs that raising production cost and the second one, improving efficiency that can produce more output with certain inputs or the same output with l...
