Accounting for Heterogeneity in Network Formation Behaviour: An Application to Vietnamese SMEs

Network formation is often characterized by homophily, i.e. the tendency of agents to connect with others who have similar attributes. However, while most agents are homophilous, others could be heterophilous; they aim to create ties with dissimilar agents. This study provides empirical evidence supporting this hypothesis by applying a random coefficient approach to data on the information-sharing networks of small- and medium-sized Vietnamese enterprises. In particular, we find that firms tend to form heterophilous links with respect to business type and gender ratio. One possible reason for the heterophily is that firms can obtain useful and performance-improving information from such dissimilar partners.     

Effectiveness of harvest strategies in achieving multiple management objectives in a multispecies fishery

Fisheries management is characterised by multiple objectives, some of which may be complementary, while others may require trade‐offs between outcomes. Balancing these objectives is made more complex in the case of multispecies and multigear fisheries. In this paper, we develop a bioeconomic model that captures the key elements of such a fishery to test a range of potential harvest strategies to provide insights into how economic target reference points could lead to both desirable and undesirable management outcomes (e.g. discards). The model is developed as a long‐run optimisation model to identify target reference points to achieve multispecies maximum economic yield, and a dynamic recursive optimisation model, which includes more realistic representation of fishers’ behaviour, such as discards and trading of under‐caught species quotas. The potential economic, social and ecological impacts are evaluated using data envelopment analysis (DEA). The results suggest that the use of proxy target reference points can result in short‐term economic benefits at the cost of slower stock recovery and higher discarding. Limiting the number of species subject to quota controls may also prove beneficial in multispecies fisheries, while ensuring quota markets are efficient is likely to produce benefits irrespective of the harvest strategy adopted.     

Bank soundness and bank lending to new firms during the global financial crisis

This paper examines how the soundness of financial institutions affected bank lending to new firms during the 2008 financial crisis by using a unique firm–bank match‐level dataset of 1,467 unlisted small and medium‐sized enterprises incorporated in Japan. We employ a within‐firm estimator that can control for unobserved firms’ demand for credit through firm ? time fixed effects. The major findings of this paper are the following four points. First, sounder financial institutions may be generally less likely to provide financing to new firms. Second, our results suggest that sounder financial institutions were less likely to provide loans to new firms during the 2008 financial crisis. Third, financial institutions were less likely to provide financing to new firms during such crisis as compared to those with the same soundness during non‐crisis periods. Finally, such lending relationships to new firms that are established during the financial crisis by sounder financial institutions are more likely to be continued than such lending by less sound financial institutions.     

Measuring the Benefits of Neighbourhood Park Amenities: Application and Comparison of Spatial Hedonic Approaches

The hedonic price method was used to estimate the influence of parks on the rental prices of single-room dwellings in Setagaya Ward, Tokyo, Japan. A simple least squares method is not optimal when the data set contains spatial autocorrelation. To improve the accuracy of estimates, we employed spatial autoregression and kriging models, resulting in a higher validity of the spatial models compared to the least squares model. Kriging models were superior to others particularly in terms of prediction accuracy, indicating that these models should be employed if the objective is superior prediction rather than estimation. The results showed that the effect of parks on property values varied with the buffer distance and park size.     

No‐take marine reserves and illegal fishing under imperfect enforcement

No‐take marine reserves have been increasingly advocated as an effective means of supporting marine ecosystems and conserving fisheries resources. A major problem that can hinder the effectiveness of no‐take reserves is the incidence of illegal fishing, which has created significant ecological and economic losses in global fisheries. We construct a bioeconomic model to explore the connection between the effects of no‐take reserves and illegal fishing activities in relation to the level of regulatory control of illegal activities in the reserve and fished areas. Our parameterised model shows that the effects of no‐take reserves on both the extent of illegal fishing and the fish biomass critically depend on illegal fishing regulations and the scale and patterns of fish dispersal. In a fishery where illegal fishing can only be partially controlled, increasing the size of the no‐take reserve may result in a lose‐lose situation in which the level of illegal fishing effort increases and the total biomass decreases. Our results further show that when the pattern of fish dispersal is density dependent, imposing a stricter control on illegal fishing in either reserves or fished areas increases the aggregate level of illegal fishing.     

Implications of firm experiential knowledge and sequential FDI on performance of Japanese subsidiaries in Brazil

A foreign firm investing in a culturally different market usually faces a certain level of uncertainty. This study proposes that as a multinational company accumulates experiential knowledge, it develops more capabilities and know-how and consequently reflects on subsidiary performance. Based on a subsidiary level sample of Japanese firms located in Brazil, the empirical findings of this study demonstrate that the accumulation of both international and local experiential knowledge can positively affect subsidiary performance. Moreover, a firm’s sequential foreign direct investment decision in the local market is a key strategy to achieving a higher level of subsidiary profitability in comparison with a first-time investment firm.

THE PERFORMANCE OF CORPORATE MERGERS IN JAPAN

This paper presents an objective and systematic analysis of the performance of corporate mergers in Japan. Two types of tests are provided. One is to compare fmancial ratios of merging firms before and after the merger. Negative effects of mergers are verified. The other is to compare the financial performances of merging and nonmerging firms before and after the merger in the same industry. No clear distinction is obtained between them. General comparisons between merging and nonmerging fms indicate negative effects of mergers.     

Partial identification in binary response models with nonignorable nonresponses

This study investigates the identification of parameters in semiparametric binary response models of the form y=1(x^′β+v+ε>0)$y=1(x^{\prime }\beta +v+\epsilon >0)$ when there are nonignorable nonresponses. We propose an estimation procedure for the identified set, the set of parameters that are observationally indistinguishable from the true value β$\beta$, based on the special regressor approach of Lewbel (2000). We show that the estimator for the identified set is consistent in the Hausdorff metric.
