日本实验电影的内与外——从1980年开始

我认为1983年是我生命中的一个转折点,但在那时我从未想过自己会在以后的日子里与实验电影结缘。那一年,北海道近代美术馆邀请日本实验电影的重要人物川中伸啓(KAWANAKA     

Belief-Based Equilibria in the Repeated Prisoners' Dilemma with Private Monitoring

We analyze repeated prisoners' dilemma games with imperfect private monitoring and construct mixed trigger strategy equilibria. Such strategies have a simple representation, where a player's action only depends upon her belief that her opponent(s) are continuing to cooperate. When monitoring is almost perfect, the symmetric efficient outcome can be approximated in any prisoners' dilemma game, while every individually rational feasible payoff can be approximated in a class of such games. The efficiency result extends when there are more than two players. It requires that monitoring be sufficiently accurate but does not require very low discounting when a public randomization device is available.

An analysis of geographical agglomeration and modularized industrial networks in a regional cluster: A case study at Yamagata prefecture in Japan

In a regional innovation system, a dense inter-organizational network within the region is recognized as a key factor in enhancing knowledge diffusion, regional learning, and effective resource transfers. Therefore, understanding the network structure and physical proximity of organizations is essential. In this paper, we investigated the industrial structure of Yamagata prefecture in Japan as a case study. Because Yamagata is a representative industrial region, the analysis can also provide an insight into other industrial regions. Initially, we investigated the geographical dispersion of firms and found them to be agglomerated along Route 13 and the Tohoku Shinkansen railroad, indicating that infrastructures for transportation still have a decisive role in terms of site location. Subsequently, we analyzed the modular structure of the inter-firm network. The results showed that hub firms construct a different type of network and play different roles within the inter-firm network, reflecting their strategic choice. The results also showed that there is a tendency for firms to transact with those in close proximity, and that firm location is also affected by the location of the hub firm in the module in addition to the infrastructures.     

Folk theorem with communication

This paper proves a new folk theorem for repeated games with private monitoring and communication, extending the idea of delayed communication in Compte [O. Compte, Communication in repeated games with imperfect private monitoring, Econometrica 66 (1998) 597-626] to the case where private signals are correlated.The sufficient condition for the folk theorem is generically satisfied with more than two players, even when other well-known conditions are not. The folk theorem also applies to some two-players repeated games.     

Inflation and public debt reversals in advanced economies

This paper quantitatively assesses the effects of inflation shocks on the public debt-to-GDP ratio in 19 advanced economies using simulation and estimation approaches. The simulations suggest that 1 percentage point shock to the inflation rate can reduce the debt-to-GDP ratio by about 0.7 percentage points on average across countries, while the estimated impulse responses are a little larger and more persistent. Additional assumptions taking into account financial repression do not necessarily make these effects substantially larger. These results imply that modestly higher inflation, even if accompanied by some financial repression, could reduce the public debt burden only marginally.     

On China’s Exchange Rate Flexibility and Stability: The More Flexible against the U.S. Dollar, the More Stable in Effective Terms

I. IntroductionFor many years, the Chinese authorities have often expressed their appreciation for the merits of a flexible exchange rate regime for China and their willingness to make the exchange rate of the renminbi, China’s national currency, be determined by market forces. 1 In the same breath, however, they also stressed the importance of a “stable exchange rate” forChina, although it is not clear what the authorities meant by a “stable exchange rate.” (The People’s bank of Chin…     

The effects of argument preparation and timing of first offer on negotiators' cognitions and performance

We investigate how argument preparation (self-only, self/counter) and the timing of the first offer (immediate, delayed) combine to affect negotiation performance. Subjects participated in a dyadic negotiation concerning the out-of-court settlement of a lawsuit. Subjects prepared by generating a list of arguments in support of their case (self-only), or by generating a list of arguments in support of their caseaccompanied by a list of counterarguments that they might expect from their opponent (self/counter). In the Immediate Offer condition, subjects began the negotiation with an exchange of written settlement offers. In the Delayed Offer condition, subjects began the negotiation with a discussion of the qualitative negotiation issues. It was proposed that negotiators who prepared both their own and counterarguments would be more flexible and that this effect would be increased by delaying the first offer. The results indicate that the effects of these variables are more complex than originally proposed, and reveal significant interactions with the negotiator's role in the conflict.The first author was supported by the IBM Faculty Research Fund at the Graduate School of Business, the University of Chicago.     

The trade credit channel revisited: evidence from micro data of Japanese small firms

It is suggested that trade credit can be a substitute for bank loans for small- and medium-sized enterprises (SMEs) that have little access to external funding sources. Using unique cross-sectional survey data of Japanese SMEs, we conduct a deep investigation into the substitutability between bank loans and trade credit. This survey contains rich information on the suppliers of trade credit to SMEs, thus enabling the examination of the channel through which credit is provided from suppliers to customers. We find that SMEs with little access to bank credit depend more on large suppliers for trade credit. We also find that when a purchase is made from a large supplier, more credit is indeed provided in the form of trade credit. Furthermore, this channel of credit from large suppliers to SMEs is only observed for solvent customers, not for insolvent customers. Our findings suggest that trade credit plays an important role for entrepreneurial firms over the financial growth cycle. For young and small firms with little access to bank loans trade credit is an important funding source.
