The Causes and Consequences of Accelerated Stock Repurchases

We examine the choice between accelerated share repurchase (ASR) and open market repurchase (OMR) as repurchase mechanisms between 2004 and 2007. For a sample of ASRs and OMRs that actually buy shares in the announcement quarter, we find that ASR firms have lower market‐to‐book ratios, less cash, but greater managerial entrenchment. Prior to repurchase, ASR firms are subject to significantly more takeover rumors than OMR firms are, and this, along with entrenchment and undervaluation, affects the choice to use ASRs. ASR firms experience positive average abnormal returns both before and after the announcement. Moreover, the latent takeover probability is significantly lower for both ASR and OMR firms (when compared with pre‐announcement levels), but the reduction for ASR firms is more pronounced. Our results suggest that repurchases, and especially ASRs, indeed make a firm a less attractive prospect for takeover.     

The profit versus loss heuristic and firm financing decisions

This paper examines the extent to which the profit versus loss heuristic directly affects debt issuance decisions. We hypothesize that reporting a loss and its use as a heuristic rather than firms’ economic fundamentals has an impact both on the decision to raise external debt finance and on the choice between debt and equity financing. The results are consistent with the hypothesis. We find that there is a sharp and economically-significant discontinuity around the zero-earnings threshold in the level of debt issues. Firms reporting small losses issue significantly less debt than firms reporting small profits. We also find that the loss heuristic has an impact on the choice between debt and equity in that loss firms issue less debt relative to equity. Taken together the results are consistent with the notion that profit versus loss heuristic impacts the debt issuance decision and provide explanations that add to those offered by the traditional theories.     

THEORY AND PRACTICE OF DECENTRALIZED PLANNING PROCEDURES

Abstract. The paper surveys the theory of decentralized planning procedures, dealing with price-guided, quantity-guided and mixed procedures. Informational and incentive properties of the various procedures are dealt with, as is the problem of public goods. The practice of planning in the USSR, Hungary and India is also discussed.     

Should the Pre‐Notification of Mergers Be Compulsory in Australia?

Australia is unusual among the world's antitrust jurisdictions in not making the pre‐notification of mergers compulsory. However, if the parties are concerned that the Australian Competition and Consumer Commission (ACCC) is likely to object to the merger, there are strong incentives for them to notify the ACCC as the regulator has developed a strong reputation for imposing heavy costs on parties that fail to notify such mergers. The result is a system of quasi‐compulsory notification that creates the strongest incentives for parties to notify the ACCC of those proposals to which it is most likely to object. This study analyses data extracted from the ACCC's merger database and the empirical results are consistent with this characterisation. Mergers reported voluntarily by the parties are found to experience longer delays to completion, and are more likely to be challenged by the ACCC, when compared with a sample of all other mergers assessed by the regulator. The results suggest that non‐compulsory notification allows the parties themselves to pre‐sort the proposed merger vis‐à‐vis its interest to the ACCC.     

On the informational efficiency of the competitive resource allocation process

The purpose of this paper is to formalize the competitive process as a parametric process, and then prove the minimality of its message space among the message spaces for a broad class of parametric processes that includes the class of processes considered by Hurwicz (in “Studies in Resource Allocation Processes” (K. J. Arrow and L. Hurwicz, Eds.), pp. 413–423, Cambridge Univ. Press, Cambridge, 1977), Mount and Reiter (J. Econ. Theory6 (1974), 161–192), and Osana (J. Econ. Theory17 (1978), 66–78). The proof of this result turns crucially on the “asymmetry property” (which is stronger than the well-known “uniqueness property” of Hurwicz) and on an injectiveness lemma which is applicable to parametric processes.     

Land-use changes, forest/soil conditions and carbon sequestration dynamics: A bio-economic model at watershed level in Nepal

A dynamic bio-economic model has been used at watershed level in Nepal to analyze the land-use changes, forest and soil conditions and their resultant impacts on carbon (C) sequestration. Planning horizon of the model extends over a period of 25 years. The objective function is maximization of the sum of discounted net income flows from agriculture, livestock and forestry productions; imputed value of leisure and labour hiring out activities subject to annual constraints on land, labour and capital availability along with the fulfilment of minimum cash and consumption requirements. The seven scenarios analyzed by the model are: business as usual (BAU), reduction in population growth rate from 2 to 1.5% p.a., increased prices of major crops by 10 and 20%, reduction in emigration of active labour force from the watershed from the current rate of 20–15 and 10%, and increase in discount rate from 5 to 10%. The results indicate that reduced labour emigration rates and increase in the prices of major crops lead to expansion of cultivated area and shift from one land use to the others. Land clearing becomes more severe with decline in labour emigration rate. Up to 10% increase in the prices of agricultural crops does not have noticeable effect on total land clearing. Increase in discount rate leads to less land clearing, more biomass harvesting and higher net C sequestration as compared to the BAU scenario. Assuming a C price of 10 USD per MgC and 5% discount rate, the net present value of C sequestration for the first 25 years is estimated at 1.83 mill USD in the BAU scenario, varying from 0.16 mill USD to 2.26 mill USD, as respectively the lowest and highest values for the seven scenarios analysed. A reduction in population growth and maintenance of current rate of off-farm employment are suggested for slowing down the expansion of cultivated land area, and thereby reducing the forest/soil degradation and C emissions. This in turn would enhance the income potential from C sequestration.     

Industry Expertise,Information Leakage and the Choice of M&A Advisors

This paper examines the impacts of M&A advisors’ industry expertise on firms’ choice of advisors in mergers and acquisitions. We show that an investment bank's expertise in merger parties’ industries increases its likelihood of being chosen as an advisor, especially when the acquisition is more complex, and when a firm in M&A has less information about the merger counterparty. However, due to the concerns about information leakage to industry rivals through M&A advisors, acquirers are reluctant to share advisors with rival firms in the same industry, and they are more likely to switch to new advisors if their former advisors have advisory relationship with their industry rivals. In addition, we document that advisors with more industry expertise earn higher advisory fees and increase the likelihood of deal completion.     

International treaties on trade and global pollution

The paper shows that global pollution need not rise under free trade in goods and/or emissions even in the complete absence of income effects. Differences in environmental concerns across the countries lead to differences in the pollution intensity of production and, thus, generate the possibility of increasing world output and income without increasing the world pollution by shifting the production of the polluting good from the country with higher pollution intensity of production to the country with lower one. We show that free trade in goods and/or emissions can induce precisely such a shifting of production with the country with greater environmental concern exporting the polluting good. The paper also demonstrates the possibility of a first-best international treaty on global pollution in which each country or group of countries is better-off.     

Repetitive risk aversion

We propose a reasonable condition, which we call repetitive risk aversion (RRA), to be imposed on any utility function to account for the observed data on the relationship between the degree of absolute risk aversion and wealth. We deduce this condition from the concept of the fear of ruin (Aumann and Kurz 1977) and show it to be equivalent to the behaviorally meaningful condition that the risk premium is increasing at a non-increasing rate with the size of the bet. We drive mixed risk aversion, which is known to be stronger than standard and thus proper risk aversion, from RRA. We present several economic applications of RRA to demonstrate that it delivers better comparative static results.I am thankful to Jacques Drèze and Louis Eeckhoudt for their comments. I greatly appreciate the comments of an anonymous reviewer of this journal which have resulted in substantial improvement to both the content and presentation of the paper. An earlier version of this paper was presented at seminars at Brown, CORE, Hopkins, HKUST, Yale, and IMS     

The nonlinear input-output model

This paper develops a nonlinear input-output model in which the production functions can exhibit a mixture of returns to scale at the various stages of production. It is shown that the traditional properties of the linear input-output model can be replicated under an extremely plausible assumption, which we call the uniform dominant diagonal condition. On the basis of this assumption it is shown that the model satisfies a contraction property. This open up the possibility of using some quite powerful results from the contraction mapping theory, establishes the existence of solutions, efficient computational procedures, and leads to a rather transparent mathematical theory for the nonlinear input-output model.
