Bondholder Wealth Effects in Mergers and Acquisitions: New Evidence from the 1980s and 1990s

We examine the wealth effects of mergers and acquisitions on target and acquiring firm bondholders in the 1980s and 1990s. Consistent with a coinsurance effect, below investment grade target bonds earn significantly positive announcement period returns. By contrast, acquiring firm bonds earn negative announcement period returns. Additionally, target bonds have significantly larger returns when the target's rating is below the acquirer's, when the combination is anticipated to decrease target risk or leverage, and when the target's maturity is shorter than the acquirer's. Finally, we find that target and acquirer announcement period bond returns are significantly larger in the 1990s.     

Endogenous screening, credit crunches, and competition in laxity

A simple model of lending with endogenous screening predicts that risk-neutral banks tend to adopt tighter lending standards under several conditions commonly seen in recessions: lower interest rates (or spreads), higher default rates, or a smaller fraction of good borrowers. Historical data support these predictions. In addition, better information about borrower types encourages tighter lending standards, and competition in laxity can arise with multiple banks. Within the class of symmetric screening decisions, endogenizing the interest rates disrupts the existence of equilibrium in pure strategies, just as when screening decisions are assumed to be exogenous.     

Security Choice, Information Effects and Firm Characteristics: A Factor Analytic Approach

Abstract:   We examine the marginal choice between debt and equity securities using a factor analytic approach. This data reduction property eliminates the need to select the one best variable to proxy for a particular theoretical construct. Our results reinforce numerous existing findings using traditional methods and suggest both static tradeoff and asymmetric information based considerations are relevant in determining security choice. Two new results are presented related to the accounting liquidity of the firm. First, the preference for equity is increasing with liquidity as suggested by the window of opportunity hypothesis. Secondly, the market response to equity issuance announcements is inversely related to the liquidity of the firm. Profitability and growth measures support Jensen's (1986) agency cost of free cash flow as a potential explanation for the second finding.     

The conditional probability and the linear flow graph approaches to analyzing probabilistic causal systems

An alternative theoretical approach to the analysis for dichotomous causal systems that involve probabilistic causation, the conditional probability approach, has recently been explicated. It was shown that there exist various composition and decomposition rules for analyzing various kinds of general causal systems, and an important distinction between pure-“or”-and pure-“and”-causal systems was explicated. In this paper these earlier results are used to analyze a causal system which has been studied by J.A. Davis (1976), who uses his linear flow graph approach to analysis. The results of the conditional probability approach are compared to the linear flow graph, and it is shown that the two approaches lead to strikingly different results.     

THE RELATIONSHIP BETWEEN FOOD PRODUCTION AND CONSUMPTION VARIABILITY: POLICY IMPLICATIONS FOR DEVELOPING COUNTRIES

This paper examines whether there is increased inter-year instability in food consumption at the national level, and to what extent this is attributable to increased instability of food production in the wake of adoption of modern agricultural technology. The data analysed indicates that increased production instability does translate into increased fluctuations in consumption. Nevertheless, year-to-year consumption variability among the sample of 38 countries has declined during the past 25 years. This is attributed to improved stocking operations and trade practices which accompany economic growth. Nevertheless, food insecurity, as measured in terms of fluctuations around trend levels of consumption, does remain a problem, especially among the poor. Therefore, policy options to reduce consumption instability are outlined.     

Invention under uncertainty and the threat of ex post entry

This article proposes a theoretical framework for studying the invention of new products when demand is uncertain. In this framework, under general conditions, the threat of ex post entry by a competitor can deter invention ex ante. Asymmetric market power in the ex post market exacerbates the problem. The implications of these general results are examined in a series of examples that represent important markets in the computer industry. The first is a model that shows how an operating system monopolist, by its mere presence, can deter the invention of complements, to its own detriment as well as that of society. The implications of policies such as patent protection, price regulation, and mandatory divestiture are considered. Three additional examples consider the ability of a monopolist in one market to commit to bundling an unrelated product, a pair of horizontally differentiated firms that can add a new feature to their products, and a platform leader that can be challenged in its base market by the supplier of a complementary product.     

On Schumpeter, Services and Economic Change

Abstract . Joseph A. Schumpeter, the Austrian-American economist, worried about “Can capitalism survive” a generation ago, and so far it has. But his work poses these questions: How do growth and change take place in a free enterprise economy? Can his model for expansion through innovation and creative destruction through the competitive process be a basis for understanding present day industrial economies? He emphasized that capitalism was an evolutionary system and that the very need for newness or rejuventation should insure continual change in it. With respect to declining industries and firms the task of economics was to turn what might have been a rout into orderly retreat. And so he gave a limited blessing to certain monopoly practices deriving from a broader strategy, risk avoidance. Schumpeter's entrepreneurs have disappeared but innovative ability still is exercised, largely through issue-specific consulting services in the burgeoning service sector, services that foster stability as well as change
