"Active Intermediation in a Monetary Overlapping Generations Economy" ( ps,297K) ( pdf,600K ), (with M. Pingle), Economic Report No. 42, Iowa State University, April 1997. Final version appears in Macroeconomic Dynamics 2 (1998), pp. 183--212. Abstract: This study demonstrates that the reason...

This paper establishes that the pro�t-seeking activities of private intermediaries can ensure Pareto e�ciency in the standard pure-exchange monetary overlapping generations economy without the need for government monetary or �scal policy intervention. Moreover, these...

First Welfare Theorem fails to hold for standard pure exchange overlapping generations economies because no agent exploits the profit opportunities which can arise from mediating intertemporal trade. This paper modifies the standard economy by introducing an optimizing corporate intermediary...

This paper establishes that the profit-seeking activities of private intermediaries can ensure Pareto efficiency in the standard pure-exchange monetary overlapping generations economy without the need for government monetary or fiscal policy intervention. Moreover, these profit-seeking...

Why does the First Welfare Theorem fail in standard overlapping generations economies with production, such as Diamond (AER, 1965) and Tirole (Econometrica, 1985)? This study argues that the reason for this failure can be attributed to the passive intermediation role played by the Walrasian...

Standard blockwise empirical likelihood (BEL) for stationary, weakly dependent time series requires specifying a fixed block length as a tuning parameter for setting confidence regions. This aspect can be difficult and impacts coverage accuracy. As an alternative, this paper proposes a new...

In current restructured wholesale power markets, the short length of time series for prices makes it difficult to use empirical price data to test existing price forecasting tools and to develop new price forecasting tools. This study therefore proposes a two-stage approach for generating...

Short-term congestion forecasting is highly important for market participants in wholesale power markets that use Locational Marginal Prices (LMPs) to manage congestion. Accurate congestion forecasting facilitates market traders in bidding and trading activities and assists market operators in...
