We investigate how the description of a correlated information V improves the investment in the stock market X . The objective is to maximize the growth rate of wealth in repeated investments. We find a single-letter characterization of the incremental growth rate (R), the maximum increase in growth rate when V is described to the investor at rate R. The incremental growth rate specialized to t...

in recent years, the existing competitions between investment companies have been increased largely by entering private investors in capital market. large and powerful companies try to achieve the goals predicted to increase the competition capacity. to analyze the efficiency of investment companies, parametric and non-parametric methods are used. in this research, based on the dissociation pow...

this paper extends endogenous growth models through augmenting it with government budget and oil revenues as well as the effect of public investment efficiency on long run growth of private and government consumption and import for an oil producing economy. based on the extracted model, the optimal growth rate of government current expenditure (or consumption) has a positive relation with the e...

This paper uses a grey forecasting model GM(1,1) on improving the investment performance of classical Markowitz efficiency frontier’s investment portfolio using the component markets’ indexes of MSCI World Index from 1999 to 2005 as the samples. Using grey Markowitz efficiency frontier’s investment portfolio models, we establish a more stable and correct connection between ex-ante model and ex-...

This paper studies the efficiency of competitive equilibria in economies where expansion investment is facilitated by securitization. We show that use securitization generally associated with constrained inefficient aggregate investment, thereby potentially justifying regulatory intervention markets for securitized assets. examine effectiveness two real-world policy instruments to address this ...

Abstract Households’ energy-saving activities are often categorized into efficiency investment and curtailment action, which previous studies have analyzed separately, even though households use both activity types simultaneously. In this study, we develop an model based on a household production framework to show how these two related. Our predicts that uses energy action jointly not alternati...
