Competing macro-hypotheses in the United States: A Kalman filtering approach

The empirical validity of alternative views about the short-run determinants of real output growth in the United States is investigated. A nested framework is used to test the macro rational expectations (MRE) hypothesis directly against two competing hypotheses - the neo-Keynesian view that anticipated and unanticpated monetary policy both matter,and Friedman's (1977) proposition that increased inflation uncertainty reduces real output at least temporarily. The unobservable explanatory variables are obtained from time-varying-parameter models of inflation and money growth, which generate forecast errors and their conditional variances consistent with rational expectations under a continuously chaning policy regime. The empirical results strongly support Friedman's view. The MRE hypothesis must be rejected since both anticipated and unanticipated monetary changes matter. The results prove robust across different model specifications and estimation techniques.

Impact of Mandatory Price Reporting Requirements on Level, Variability, and Elasticity Parameter Estimations for Retail Beef Prices

Moving to scanner based and quantity-weighted monthly average retail beef price series has changed the price series significantly. Quantity-weighted price levels are lower and more volatile. Perhaps most important, calculated elasticities for the quantity-weighted averages are lower than for the historical simple average data. Elasticity estimates for simple average monthly price data are also larger than for weekly data, raising the possibility that historic demand analyses have significantly overstated own price demand elasticities.     

RETURNS TO SHAREHOLDERS IN SUCCESSFULLY DEFENDED TAKEOVER BIDS: UK EVIDENCE 1975–1984

This study examines the economic performance of target and bidding companies where the target successfully defended a hostile takeover bid in the period 1975–1984. Returns to shareholders in both target and bidding companies are measured for the six months preceding the bid, and for the twenty-four months after the bid. The study finds that the significant gains obtained by shareholders in the target company around the time of the bid announcement are not lost after the failure of the bid. In apparent defiance of the efficient market hypothesis abnormal returns continue for the two years after the bid. As for the bidding company, the small positive abnormal returns to its shareholders are also sustained after the bid.     

Sabotage in Corporate Contests – An Experimental Analysis

In corporate contests, employees compete for a prize. Ideally, contests induce employees to exert productive effort which increases their probability of winning. In many environments, however, employees can also improve their own ranking position by harming their colleagues. Such negative incentive effects of corporate contests are largely unexplored, which can partly be attributed to the fact that sabotaging behavior is almost unobservable in the field. In this study we analyze behavior in experimental contests with heterogeneous players who are able to mutually sabotage each other. We find that sabotaging behavior systematically varies with the composition of different types of contestants. Moreover, if the saboteur’s identity is revealed sabotage decreases while retaliation motives prevail. Our results promise to be valuable when designing corporate contests.
