The trend of UK logistics warehouses is reported towards larger and more centralized systems on which automation is heavily invested in recent years. This is partially because of the disadvantage of manual operation resulting in the slow storage and retrieval speed, the high labor cost, and the...

Since the Morris worm was released in 1988, Internet worms continue to be one of top security threats. For example, the Conficker worm infected 9 to 15 million machines in early 2009 and shut down the service of some critical government and medical networks. Moreover, it constructed a massive...

We develop an endogenous growth model incorporating the spirit of capitalism and examine how it influences innovation and economic growth. In the benchmark homogeneous-ability model, we find that the spirit of capitalism increases both the capital accumulation rate by enhancing consumer patience...

We reexamine the optimal fiscal and monetary policy in combined shopping-time monetary models with capital accumulation. Four models are constructed to examine how the production cost of money and the utility from physical capital affect the toolbox of the fiscal and monetary policy. It is shown...

This paper develops a simple mercantilism model for a small open economy and examines the real effects of macroeconomic policies. In this setting, the saddle-point stability of the model with wealth effects hinges on an interesting "relative smoothness condition" for foreign asset accumulation....

In this paper, we study risk-taking, fiscal policies, and asset pricing in a stochastic model of growth with non-expected utility function and the spirit of capitalism. With specific assumptions on the production technology, preferences, and stochastic shocks, we derive the explicit solutions to...

This paper outlines a dynamic model with three levels of government: federal, state and local in the Stackelberg game structure with the superor government as the leader and all its subordinate governments the followers.It studies the optimal design of block grants and matching grants from both...

In this paper, we have studies the effects of macroeconomic policies on foreign asset accumulation in a wealth effect model used by Bardhan (1967), Kurz (1968), Calvo (1980) and Blanchard (1983). Our results differ dramatically from the ones in Obstfeld (1981). In particular, we have shown that...

The paper examines the famous Chamley-Judd zero capital tax theorem in model economies where agents care about their social status. We show that the limiting capital income tax is not zero in general and its sign depends only on the utility specifications. Our conclusion is robust to several...
