the theoretical base of this paper is the economic growth model that completed with capital stocks (private and public) and human capital. at the first, hypothesis test about constant returns to scale is studied, and then the related variables with macroeconomic policies are added to the model. the results show that 1) the aggregate production function exhibits increasing returns to scale, 2) p...

This paper examines how public disclosure affects private information acquisition activity in a market economy. We analyze a setting where traders with short-term investment horizons are allowed to trade on their private information prior to a public disclosure. We demonstrate in this setting that public disclosure stimulates investment in private information acquisition. This result is shown t...

Regulation and other forms of public policy toward infrastructure industries were and are designed to support the necessary large-scale investment. Throughout history, with few exceptions, rather pragmatic approaches guided policies. A more rigorous lens was only applied more recently although it often focuses on narrow aspects of regulation. In contrast, this paper develops a broader, integrat...

Modifying the proof of a theorem of Wilkie, it is shown that if a one dimnsional set S is definable in an O minimal expansion of the ordered field of the reals, and if it is regularly exponentially near to many integral points, then there is an unbounded set, which is R definable without parameters, and which is exponentially near to S.

In this article we will describe some of the main developments in interest-rate modelling since Black & Scholes’ (1973) and Merton’s (1973) original articles on the pricing of equity derivatives. In particular, we will focus on continuoustime, arbitrage-free models for the full term structure of interest rates. Other models which model a limited number of key interest rates or which operate in ...

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...

Within the public sector domain there is great potential for business process optimization through ICT. However, until today these possibilities remain largely unexploited. To measure the impact of ICT-investments all processes of a public administration have to be taken into account. The PICTURE modelling method has been proposed as a way to efficiently model the whole process landscape of a p...
