THE ANNOUNCEMENT EFFECTS OF PREFERRED STOCK RE-RATINGS

This paper examines the equity return behavior of firms whose preferred stock ratings have been changed by Standard and Poor's. The evidence indicates that the market anticipates the re-ratings by approximately 40 days for the complete sample. However, the downgrades for the utility subsample do not experience any downward drift before or after the re-rating. In general, these results support the previous findings of Pinches and Singleton (1978) and Weinstein (1977).     

Dynamic input demand functions and resource adjustment for US agriculture: state evidence

The paper presents an econometric model of dynamic agricultural input demand functions that include research based technical change and autoregressive disturbances and fits the model to annual data lor a set of stale aggregates pooled over 1950-1982. The methodological approach is one of developing a theoretical foundation for a dynamic input demand system and accepting state aggreage behavior as approximated by nonlinear adjustment costs and long-term profit maximization. Although other studies have largely ignored autocorrelation m dynamic input demand systems, the results show shorter adjustment lags with autocorrelation than without. Dynamic input demand own-price elasticities for the six input groups are inelastic, ami the demand functions possess significant cross-price and research effects.     

ANALYST BEHAVIOR SURROUNDING TENDER OFFER ANNOUNCEMENTS

We examine the usefulness and credibility of analyst recommendations by focusing on their behavior surrounding tender offer announcements. For our 1998–2001 sample, we find analysts did not identify takeover targets through their recommendations nor did they distinguish between wealth‐increasing and wealth‐decreasing tender offers. We find some evidence of conflicts of interest in analyst recommendations, but it is confined to the 1999–2000 dot‐com period. However, the long‐run performance following recommendations suggests that these conflicts have little ultimate cost to investors.     

The Assessment: Games and Coordination

Coordination problems arise in a multitude of economic interactions.Recent advances in the field of game theory have shed new lighton these problems and the ways in which they might be analysed.This issue of the Oxford Review of Economic Policy first examinessome of the theoretical dimensions to this literature, as wellas some empirical and experimental insights. It goes on to applysome of these ideas to a number of important policy areas, includingmacroeconomic policy coordination, public good provision, andproblems of political coordination.     

House Prices, Fundamentals and Bubbles

Abstract:  This paper studies actual (real) house prices relative to fundamental (real) house values. Such a focus is warranted since housing constitutes a large fraction of most household portfolios, and its characteristics are such that, in contrast to what prevails in financial markets, arbitrage will be limited and hence correction toward 'true' value is likely to be a prolonged process. Using UK data and a time-varying present value approach, our results preclude the existence of an explosive rational bubble due to non-fundamental factors. We further find that intrinsic bubbles have an important role to play in determining actual house prices although price dynamics appear to impact, particularly in periods of strong deviation from fundamental value. Price dynamics are found to be driven by momentum behaviour.     

A Test for Price Pressure Effects in Tender Offer Stock Repurchases

The evidence in this paper supports the hypothesis that the previously documented stock price reversal following a tender offer announcement is consistent with a price pressure caused by a temporary shift in the security's demand curve. The authors came to this conclusion by redocumenting the price reversal, by finding an increase in trading volume around the tender offer announcement and expiration, by showing the increase in volume to be larger than expected from only an information effect, and by showing that short selling activity increases after the announcement and before the expiration of the tender offer.
