Search Frictions,Real Rigidities,and Inflation Dynamics

The literature on New Keynesian models with search frictions in the labor market commonly assumes that price setters are not actually subject to such frictions. Here, I propose a model where firms are subject both to infrequent price adjustment and search frictions. This interaction gives rise to real price rigidities, which have the effect of slowing down the adjustment of the price level to shocks. This has a number of consequences for equilibrium dynamics. First, inflation becomes less volatile and more persistent. More importantly, the model’s empirical performance improves along its labor market dimensions, such as the size of unemployment fluctuations and the relative volatility of the two margins of labor.     

Partial Revelation of Information in Experimental Asset Markets

We develop a model of market efficiency assuming private information is partially revealed to uninformed traders via the behavior of those who are informed. This partial revelation of information (PRE) model is tested in fourteen computerized double auction laboratory markets. It explains the market value and allocation of purchased information, and asset allocations, better than either a fully revealing information model (FRE strong-form efficiency) or a nonrevealing expectations model; but it takes second place to FRE in explaining asset prices. We conjecture that refined versions of PRE may provide insight into “technical analysis” and minibubbles in securities markets.     

MEASURING THE TRUE HARM FROM PRICE‐FIXING TO BOTH DIRECT AND INDIRECT PURCHASERS*

Legal actions by direct and indirect purchasers to recover damages from price‐fixing, common in the United States for years, are now appearing in a number of other countries. Traditional measures of damages are flawed as measures of the true harm suffered and will often significantly understate that true harm. This paper provides measures of the degree of understatement of the true harm when traditional approaches are used and shows how the size of the error depends on the degree of competitiveness of downstream markets. The paper also provides measures of distribution of the true harm between direct and indirect purchasers.     

NATIONAL SECURITY AND INDUSTRIAL POLICY: THE NEED FOR A PUBLIC CHOICE PERSPECTIVE

This paper argues that the issues raised by the industrial policy debate are as much political as they are economic. There is every reason to believe that, without substantial reform of political institutions, efforts to administer a rational new industrial policy would soon degenerate into the type of inconsistent morass of special-interest-generated policies which industrial policy advocates rightfully criticize as our de facto set of industrial policies.
This important political dimension has been overlooked by many industrial policy advocates. An important exception is Robert Reich, who has proposed a new centralized industrial policy agency in hopes that the battle of conflicting interests would promote greater aggregate efficiency. We argue that on theoretical grounds, however, such centralization might either increase or decrease efficiency. The competition of the military services under the Defense Department gives us a close analogue for study. Unfortunately, however, our review of efficiency in defense policy suggests that this would be a very poor model on which to base a broader industrial policy. To promote substantial increases in defense and industrial policy efficiency appears to require that much more fundamental institutional reforms be considered.     

Free Cash Flow,Issuance Costs,and Stock Prices

We develop a dynamic model of a firm facing agency costs of free cash flow and external financing costs, and derive an explicit solution for the firm's optimal balance sheet dynamics. Financial frictions affect issuance and dividend policies, the value of cash holdings, and the dynamics of stock prices. The model predicts that the marginal value of cash varies negatively with the stock price, and positively with the volatility of the stock price. This yields novel insights on the asymmetric volatility phenomenon, on risk management policies, and on how business cycles and agency costs affect the volatility of stock returns.     

Risk A version and Information Structure: An Experimental Study of Price Variability in the Securities Markets

This study investigates the differences in the behaviors between the speculative investors and the conservative investors in two separate experimental markets. Although the market for speculators shows greater price volatility in both bid/ask spread within a trade as well as with intraperiod variances, it exhibits several desirable properties. Specifically, the price patterns tend to converge closer, and at a greater speed to either the prior information equilibrium price or the rational expectation equilibrium price. It also achieves better allocational efficiency. And, it is also less likely to be misled by potentially “false” price information.     

On Constructing an EPS Measure: An Assessment of the Properties of Dilution*

This paper evaluates the information content of the treasury stock method for computing diluted earnings per share (EPS). We demonstrate that the treasury stock method decreases the annual association between earnings changes and stock returns and explain why this is the case. Further, we show that the treasury stock method leads to a dilutive adjustment that biases the random walk model of annual earnings in a predictable direction. Finally, we demonstrate that using the treasury stock method appears to confuse both analysts and investors: analysts' forecast errors increase with the size of the dilutive adjustment, and the association between unexpected earnings and stock returns at the earnings announcement date weakens as the dilutive adjustment increases.
