A Continuous-Time Analysis of Optimal Restructuring of Contracts with Costly Information Disclosure

This paper studies the role of restructuring, as compared to the one of liquidation, in valuation of long-term debt contracts in a continuous-time model with costly information disclosure. In asset-pricing literature, Merton??s (J Finance 29:449?C470, 1974) contingent-claim models have been long used for valuation of corporate securities and loans. However, since they basically assume sufficiently complete security structures in markets, the literature is not necessarily suitable for examining costly-information problems. On the other hand, in corporate-finance literature, it has been well known that agency costs (i.e., conflicts of interest among agents) distort corporate capital structure under costly-information problems. However, the effect of the distortion on valuation of securities and loans has not been explicitly studied either in theory or in practice. This paper bridges such a gap between the two literatures. This paper shows that, under a costly-information problem, corporate leverage ratios are higher when restructuring is expected to be accepted in default than otherwise. The risk of a jump to liquidation increases the default probability in short term, and decreases the probability of restructuring over time.     

On estimating Armington elasticities for Japan's meat imports

By fully accounting for the distinct tariff regimes levied on imported meat, we estimate substitution elasticities of Japan's two-stage import aggregation functions for beef, chicken and pork. Although the regression analysis crucially depends on the price that consumers face, the post-tariff price of imported meat depends not only on ad valorem duties but also on tariff rate quotas and gate price system regimes. The effective tariff rate is consequently evaluated by utilising monthly transaction data. To address potential endogeneity problems, we apply exchange rates that we believe to be independent of the demand shocks for imported meat. The panel nature of the data allows us to retrieve the first-stage aggregates via time dummy variables, free of demand shocks, to be used as part of the explanatory variable and as an instrument in the second-stage regression.     

Public Pension Benefits Claiming Behaviour: new Evidence from the Japanese Study on Ageing and Retirement

The present study explores public pension claiming behaviour among the Japanese elderly. First, we perform financial simulations, estimate expected utility and depict the typical patterns of pension benefits over a lifecycle. We show that a beneficiary's optimal retirement age depends on that beneficiary's mortality risk, discount rate, initial wealth and risk attitude. Second, we use individual‐level data from the Japanese Study on Aging and Retirement (JSTAR) to empirically examine the determinants of claim timing. We find evidence that most of the factors examined in the simulation are, indeed, significantly associated with early claiming among wage earners of pension benefits.     

Firms' open innovation policies,laboratories' external collaborations,and laboratories' R&D performance

The value of the open innovation approach is now widely recognized, and the practice has been extensively researched, but still very little is known about the relative impact of firm‐level and laboratory‐level open innovation policies and practices on R&D performance. This study attempts to measure that impact by analyzing a sample of 203 laboratories of Japanese firms located in Japan. It examines simultaneously the effects of firm‐level open innovation policy and laboratory‐level external collaborations on laboratory R&D performance. The study aims to go beyond a general understanding of the importance of open innovation; it shows how an open innovation policy can have a positive and significant effect on collaborations between a laboratory and local universities or business organizations. The results also show how an open innovation policy can contribute to the laboratory's R&D performance by facilitating external collaborations by the laboratories. It demonstrates how these factors affect R&D performance in different ways, depending on the type of R&D tasks. Our findings suggest several theoretical and practical implications in the field of R&D management.     

Interest Rate,Currency and Equity Derivatives Valuation Using the Potential Approach

Based on the potential approach to interest rate modelling, we introduce a simple tractable model for the unified valuation of interest rate, currency and equity derivatives. Our model is able to accommodate the initial term structure of zero‐coupon bond prices, generate positive and bounded interest rates, and handle cross products such as differential swaps, quanto options and equity swaps. As our model is specified under the actual probability measure, it can be directly used for portfolio risk management and the computation of value at risk. Furthermore, our model yields simple analytical formulas that are easy to calibrate and implement.     

Analytical Solutions for Expected Loss and Standard Deviation of Loss with an Additional Loan

We evaluate the expected loss and the standard deviation of loss of a bank loan, considering the bank’s strategic control of the expected return on the loan. Assuming that the bank supplies an additional loan to minimize the expected loss of the total loan, we provide analytical formulations for the expected loss and the variance of loss with bivariate normal distribution functions. Using a given expected growth rate and interest rates, two thresholds for the asset/liability ratio can specify three cases. The bank supplies an additional loan to decrease the expected loss in two cases: (i) the asset/liability ratio of the firm is low, and its expected growth rate is high; and (ii) the asset/liability ratio of the firm is high, and the lending interest rate is high. The bank maintains the current loan amount when the asset/liability ratio lies between the two thresholds. Depending on the bank’s strategy, the bank can decrease the initial expected loss of the loan. Conversely, the bank would face a greater risk of the standard deviation of loss.     

Class Struggle or Embedded Markets? Marx,Polanyi and the Meanings and Possibilities of Social Transformation

Marx and Polanyi both held that socialism, in one form or another, was a preferable and possible alternative to capitalism. Their ideas are seen to offer theoretical tools to understand the tensions and contradictions of capitalism, and to inform ways to overcome them. This paper discusses Polanyi's work from a Marxist perspective in order to illuminate his strengths and weaknesses. Its main focus is to discuss Polanyi's juxtaposing of commodification against exploitation, in diagnosing the problems of capitalist expansion. We suggest that by juxtaposing these two moments, Polanyi not only misses out on a crucial arena of capitalist activity (exploitation), but also undermines his own explication of processes of commodification. This has deleterious consequences for his understanding of the prevalence of poverty under capitalism. It also means that his vision of social transformation and of socialism is profoundly different, and potentially antithetical, to that of Marx. We suggest that for Polanyi's conception of de-commodification to gain greater traction it needs to be combined with Marx's analysis of exploitation and class struggle.     

Corrigendum to “Stable matchings and preferences of couples” [J. Econ. Theory 121 (1) (2005) 75–106]

We correct an omission in the definition of the domain of weakly responsive preferences introduced in [B. Klaus, F. Klijn, Stable matchings and preferences of couples, J. Econ. Theory 121 (2005) 75–106] or KK05 for short. The proof of the existence of stable matchings [KK05, Theorem 3.3] and a maximal domain result [KK05, Theorem 3.5] are adjusted accordingly.
