Discrete-time models of asset pricing have hitherto generally avoided studying the relationship between the underlying technology inherent in the economy and the determinants of the price of capital. A fully articulated economy is constructed in which there is a nontrivial technology for producing capital. The existence of adjustment costs in augmenting the quantity of capital has interesting implications for the stochastic properties of asset prices, as well as other macroeconomic variables. Examples of such economies are used to illustrate this point.

This paper derives the value of Pension Benefit Guarantee Corporation (PBGC) pension insurance under two scenarios of interest. The first allows for voluntary plan termination, which appears to be legal under current statutes. In the second scenario, termination is prohibited unless the firm is bankrupt. Empirical estimates of PBGC liabilities are calculated. These show that prospective PBGC liabilities greatly exceed current reserves for plan terminations, that even under a bankruptcy-only termination rule, PBGC liabilities still would be quite sensitive to discretionary funding policy, and that the increasingly common practice of pension spinoff/terminations, substantially increases the present value of the PBGC's contingent liabilities.

Securities trading is accomplished through the execution of orders. Admissible orders (e.g., market orders, limit orders) give rise to discontinuous aggregate demand functions, composed of many “steps.” Demand smoothing, or the balancing of excesses due to such discontinuities via intervention, is one of the most basic functions that could be assigned to a “specialist.” When the specialist's “affirmative obligation” is fully specified, his or her activity can in principle be automated. This paper is an attempt to assess, via simulation, some of the ramifications of using a “programmed specialist,” whose automated market making is limited to demand smoothing. A number of alternative rules of operation are simulated. Several of the rules performed well, especially the extremely simple rule that calls for the (computerized) specialist to minimize new absolute share holdings in each security at each trading point via “total” (as opposed to “local”) demand smoothing. Our results indicate that the underlying costs of demand smoothing are on the order of a fraction of a penny per share traded even in relatively thin markets.

This paper models an individual's trading decision, given: (1) his/her demand function to hold shares of an asset, (2) his/her expectation on what the market clearing price will be, and (3) the design of the market which determines how orders will be translated into trades. The particular market design we consider is the batched trading (periodic call) regime. Assuming investors are distributed according to their propensities to hold shares, we model the aggregation of orders to obtain market clearing values of price and volume and to show the way in which, with trading friction, these solutions differ from Pareto efficient values. The importance of this analysis for various issues concerning market design is noted.
