This paper investigates the role of foreign exchange reserve investment to hedge overall macroeconomic risks. Different from usual micro profit-maximizing purpose, the investment with macro objective is unique in the field of foreign reserve investment. We propose a framework of...

This paper focuses on the duopoly substitutability product with an upstream input subjected to capacity constraints. The effects of capacity constraints are captured. Combining competition effect with constraint effect, some interesting conclusions are reached. First, the relationship between...

We develop a general equilibrium endogenous growth model in which final goods can be produced either in the Non-Observed Economy (NOE) or in the Official Economy (OE). In particular, by solving transitional dynamics numerically towards the unique and stable steady state, we show that, by...

This paper is concerned with solving a vendor–buyer integrated inventory problem with rework and a specific multi-delivery policy by a two-phase algebraic approach. Conventional method to the problem is to use differential calculus and Hessian matrix equations to prove convexity of system cost...

This paper examines a vendor–buyer integrated system that includes rework and an enhanced product delivery policy that aims at lowering stock holding costs for both the vendor and the buyer. It extends the recent work of Chiu et al. (2011) by incorporating an amending ‘n+1’ shipment policy...

A theory of a wealth maximizing, capital accumulating, price taking firm facing adjustment costs and operating in the presence of disembodied and price-induced technical progress is developed. The testable implications of the extended theory are derived under mild assumptions and are thus...

We comparatively study optimal economic growth in a simple endogenous growth model and under two different games, i.e., dynamic sequential game and cooperative stochastic differential game, between a representative household and a typical self-interested politician. Sequential equilibrium...

We explore the role of habit formation in housing in explaining the life-cycle household allocations. Empirical studies about households in the U.S. reveal that the housing profile increases monotonically until age mid-60s and then flattens out. The model is realistically calibrated and solved...

Firms' quality commitment can efficiently improve the demand. This paper addresses the quality commitment under the duopoly. By establishing a Cournot model, the effects of quality commitment are discussed. Firstly, under one-sided quality commitment, the higher efficiency firm committing in...

This paper considers a strategy for the extraction and production of non-renewable resources that are finite in quantity. Specifically, we illustrate empirical data on reserves, production, consumption, and price evolution for fossil fuel. Our model is an intertemporal model of a short decision...
