Knowledge that Transforms

Numerous studies have shown that the valuation effects of corporate policies are conditioned on corporate control. A partial acquisition serves as a unique form of corporate control that has not been thoroughly researched as a control mechanism. When firms are partially acquired, the impact of their subsequent corporate policies may be affected by the degree of control imposed by the partial acquirer. Our primary objective is to test this hypothesis by (1) measuring valuation effects of the partial target and partial acquirer in response to policies enacted by the partially acquired firm (after becoming a partial target), and (2) conducting a comprehensive cross-sectional analysis for each policy which incorporate proxies for the degree of control by the partial acquirer. We find that partial targets and partial acquirers experience significant valuation effects in response to some policies enacted by the target. We also find that the valuation effects on a partial target in response to its subsequent policies are commonly conditioned by the degree of the partial acquirer's control.

This study investigates the relationship between bank lending to small businesses, banking company size and complexity, and bank consolidation. We consider two potential influences on small business lending associated with changes in the size distribution of the banking sector. On the one hand, organizational diseconomies may increase the costs of small business lending as the size and complexity of the banking company increases. On the other, size-related diversification may enhance lending to small businesses. We find first that small business loans per dollar of asset rises, then falls, with banking company size, while the level of small business lending rises monotonically with size. Second, consolidation among small banking companies serves to increase bank lending to small businesses, while other types of mergers or acquisitions have little effect. We interpret these findings as consistent with the diversification hypothesis.

This paper investigates the wealth effects of 134 divestments by 41 firms that underwent leveraged buyouts in the 1980s. Stock in these companies is privately owned. Bond returns for publicly traded debt are used to measure the wealth effects of the divestment announcement. These divestments are, on average, not associated with significant wealth effects for the full sample. However, firms that experience financial distress have negative and significant abnormal returns associated with their divestments, while returns in non-event months are insignificant. In contrast, non-distressed firms gain when asset sales are announced. The losses suffered by bondholders in distressed sellers are large and significant when core assets are divested. Bondholders in these firms do not suffer significant losses when non-core assets are divested. Finally, abnormal bond returns are related to the structure of the firms' post-buyout debt. Returns are negatively related to the use of private debt in the capital structure and positively related to the use of subordinated debt.

This paper provides a simple and practical approach to hedging bonds that are subject to credit risk. Three new hedge ratios are derived and tested and the roles of basis risk and diversification is investigated. Empirical tests reveal that basis risk is an important factor in hedging corporate bonds. These tests identify a need for new interest rate derivatives where the underlying asset is subject to credit risk.

This paper summarizes nine case studies, by nine authors, on the efficiency effects of bank mergers. The mergers selected for study were ones that seemed relatively likely to yield efficiency gains. That is, they involved relatively large banks generally with substantial market overlap, and most occurred during the early 1990s when efficiency was getting a lot of attention in banking. All nine of the mergers resulted in significant cost cutting in line with premerger projections. Four of the nine mergers were clearly successful in improving cost efficiency but five were not. It is not possible to isolate specific factors from these mergers that are most likely to yield efficiency gains, but the most frequent and serious problem was unexpected difficulty in integrating data processing systems and operations.

The nature and extent of intertemporal adjustments across stock index futures and cash markets in the UK are investigated in terms of partial adjustment factors. This approach affords the means of establishing both differential price movements in these markets and, additionally, providing a readily interpretable measure of the degree of such relative price movements. Analytic expressions are developed for jointly measuring the partial adjustment factors in cash and futures markets using a partial adjustment with noise model. The measures are adjusted for non-synchronous trading and asymptotic sampling variances derived. Adjustment factors are estimated using daily data over the period 1984–1992, with differencing intervals ranging from one to thirty days. Price adjustments were found to be fuller in futures markets, particularly over shorter differencing intervals. Corrections for non-synchronous effects in the cash market increased the magnitude of price adjustment, as did the exclusion of data from the 1987 crash period.

Economists have begun using methods borrowed from the physical sciences to search for non-linearities in economic and financial data. The so-called phase portrait from chaos theory, in which the values of a time-series are plotted against their delayed values, is one of the techniques employed for this purpose. It has recently been shown, however, that when returns on traded assets are plotted in this manner in two- or three-dimensional space, surprising patterns arise which seriously distort the conclusions that can be drawn about the underlying data. These patterns – which resemble a compass rose – reflect the microstructure of the market or, more specifically, the finite size of the “ticks” by which prices can change in a market. The present paper clarifies the reason for this phenomenon. It is shown that within the microstructure there exists nanostructure that becomes visible only when the computations are performed without approximation. High frequency data from a foreign exchange market are used to illustrate this phenomenon.

This paper develops a post-tax asset pricing model under the assumption that investors cannot defer the taxation of capital gains by costlessly short selling tax exempt perfect substitute securities. Contrary to existing literature, it is demonstrated that trading rules of immediate realization of losses and voluntary deferral of gains may not be optimal. Further, equilibrium prices are shown to be higher for stocks held by investors with large accrued capital gains and lower for stocks held by investors with small accrued capital gains or losses.
