Immigration has long been a hotly debated issue. The core of this debate is immigrants' impact on local job markets. Some people insist that instead of creating more jobs, immigrants actually take away more jobs thus decrease the living standard of natives. Others argue that the presence of...

This paper discusses a portfolio adjusting problem with additional risk assets and a riskless asset in the situation where security returns are given by experts' evaluations rather than historical data. Uncertain variables are employed to describe the security returns. Using expected value and...

It is widely feared that environmental degradation induced by climate change may lead to economic and political insecurity through channels such as resource scarcity and mass migration. In this paper, we have developed an agent-based model to study whether resource scarcity is likely to lead to...

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...

Recent research suggests that some countries may be unable to use productively their schooling output because of the scope of cronyism or corruption. We investigate further and demonstrate that, in a stylised model, cronyism in the labour market, (e.g. the ability to exert influence to gain high...

We explore bifurcation phenomena in the open-economy New Keynesian CGG Model based on Clarida et al. (2001, 2002). We find that the open economy framework can bring about more complex dynamics, along with a wider variety of qualitative behaviors and policy responses. Introducing parameters...

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...
