this paper empirically investigates the relationship between cpi inflation uncertainty, and private investment in the iranian economy from 1988 to 2010 by using quarterly data. we employ a bivariate var(5)-garch(1,1)-in-mean with diagonal bekk model to discover in a unified framework how are the interactions between the variables. in the model, conditional variance of inflation and private inve...

Real world investment decisions are generally made sequentially over time. The possibility of subsequent decisions like suspending a project must be considered when an initial investment decision is made. This seems to be particularly important in the case of investments, which take a long 'time to build'. This paper analyzes the impact of lags between the initial investment decision and the co...

Many government policies either target the underlying supply infrastructure or have indirect effects on market structure. In this paper we seek to understand the impact of the Critical Access Hospital (CAH) program on the U.S. rural hospital infrastructure and societal welfare. This program provides generous reimbursement to hospitals in exchange for size and service limitations. We specify and...

This paper established a system dynamics model of energy saving and emission reduction in coal mining area, as well as conducted simulation of different development plans, based on the analysis of energy saving and emission reduction factor of coal production links, of the complex structure of energy saving and emission reduction system in coal mining area, and of the dynamic feed-back mechanis...

Objective: This paper presents a long-term dynamic multi-objective model for distributed generation investment. In this model, sizing, sitting of DG units and specially the dynamics of investment over the planning period is considered as three objectives as multi-objective optimization problem. Accordingly, the multiobjective Interactive Artificial Bee Colony (IABC) is implemented for solving t...

I develop a dynamic model of collateral circulation in a repo market, where a continuum of institutions borrow from and lend to one another against illiquid collateral. The model emphasizes an important tradeoff. On one hand, easier collateral circulation makes repos liquid and increases steady state investment through several multiplier effects, improving economic efficiency. On the other hand...

The paper presents a mathematical model of optimal investment in illiquid assets. Specifically, the model addresses the problem of an investor with limited capital resources, who makes sequential decisions on long-term investments under uncertainty as to future opportunities. The model demonstrates that such an investor will optimally demand a higher rate of return on investments in long-term, ...

We estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on United Kingdom data. Our estimates suggest that price stickiness is a more important source of nominal rigidity in the U.K. than wage stickiness. Our estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects govern...

This paper studies how the difference between technical depreciation and tax depreciation affects the firm’s optimal investment strategy. The objective is maximization of shareholder value. When tax depreciation differs from technical depreciation, an additional investment not only generates value due to the fact that the firm can produce more, but also due to the fact that an additional deferr...

Financial factors and ownership structure are both part of the determinants of corporate R&D investment. Considering listed firms in the R&D intensive industries during the 2000s, this paper examines whether financial factors and ownership structure explain R&D investment in Japan. Following the methodology of Brown et al. (2009), which extends the dynamic investment model of Bond and Maghir (1...
