Keynesian Inefficiency and Optimal Policy: A New Monetarist Approach

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A Taylor rule neither implies determinacy, nor does it support an efficient outcome. An optimal policy yields an efficient and determinate allocation of resources, but equilibrium policy actions, wages, and prices are indeterminate at the optimum.     

Consumer microwave use of melt-blown material for fat reduction

Consumers, who use their microwave oven to heat bacon, were asked to heat either bacon or sausage on non-woven, melt-blown material and on paper towels in the microwave oven. The consumers were surveyed about their concerns for fat and cholesterol in the diet. The panelists also were asked to evaluate the appearance, greasiness, ease of use and overall acceptability. A survey of the consumers indicated that they were concerned about fat and cholesterol in the diet and purchased items lower in fat. However, 28% of these individuals save and re-use bacon fat. Panelists liked the appearance of bacon heated in the melt-blown pad better than on the paper towels and found it easier to use. Sausage heated in the melt-blown pad was found to be less greasy and more acceptable than that heated on paper towels.     

Immigration of Nurses

This paper examines the effects of immigration on a specific occupation, registered nurses (RNs). To learn whether immigrant nurses reduced the earnings of RNs, we applied techniques developed by Goldin (1994) and Borjas, Freeman, and Katz (1996), but found the effect of immigrant penetration either positive or insignificant. We also found that the supply of immigrant RNs was far more elastic than the supply coming from natives. It is often argued that it will be hard to detect negative effects on wages and employment of natives in local markets, because natives will avoid a market which many immigrants have entered. This study finds no support for this hypothesis in this market, based on data that measures the rate of entry of RNs exactly. We find no adverse effect of immigration on native workers in this occupation.     

ESTIMATING THE NON-ENVIRONMENTAL CONSEQUENCES OF GREENHOUSE GAS REDUCTIONS IS HARDER THAN YOU THINK

Top-down and bottom-up models of the non-environmental consequences of policies to reduce greenhouse gas emissions embody different implicit theories of economic organizations. Yet neither approach is explicit in showing the detailed computations that must be traced if the activities of firms are to be described realistically. Specification of firms' computational processes leads inevitably to a consideration of potential computational limits on the behavior of organizations. It is known that solutions of some standard economic problems are not effectively computable, and that the solutions to others are computationally intractable. These fundamental computational limits have strong implications for the theory of the firm, and recognizing their existence and importance suggests new policy approaches for reducing greenhouse gas emissions.

A Comparison of Dividend,Cash Flow,and Earnings Approaches to Equity Valuation*

Standard formulas for valuing the equity of going concerns require forecasting payoffs to infinity but practical analysis requires that payoffs be forecasted over finite horizons. This truncation inevitably involves often-troublesome terminal value calculations. This paper contrasts dividend discount techniques, discounted cash flow analysis, and techniques based on accrual earnings when each is applied with finite-horizon forecasts. Valuations based on average ex post payoffs over various horizons, with and without terminal value calculations, are compared with ex ante market prices to discover the error introduced by each technique in truncating the horizon. Valuation errors are lower using accrual earnings techniques rather than cash flow and dividend discounting techniques. The accounting features that make a given technique less than ideal for finite horizon analysis are also detailed. Conditions where a given technique requires particularly long forecasting horizons are identified and the performance of the alternative techniques under those conditions is examined.
