日本经济起飞时期农村劳动力供给机制研究

20世纪60年代,伴随着日本经济起飞,城市加工产业对劳动力的需求急剧扩大,在城乡巨大收入差距的诱惑下,日本农村的青壮年劳动力大量涌入城市,造成农村劳动力严重短缺,在农户家庭内部劳动力互补机制的作用下,缓解了劳动力不足,在一定程度上稳定了农业生产.从分析日本经济起飞时期农村劳动力的结构变动入手,通过实证分析把握劳动力供给结构变化的经济影响;进而分析未来日本劳动力供给结构变化的趋势,在此基础上结合中国的实际情况说明农村劳动力互补机制对于城市化进程中中国农村的借鉴意义.     

The incentive for export subsidies under imperfect competition

By taking into account factor market interactions, the theory of strategic trade policies can consistently explain the fact that less efficient countries offer greater export subsidies to the most technologically advanced industries because in these countries there may be greater differences in efficiency of production technology between industries than in more efficient countries.     

The Substitution Effect of Mobile Games on Console Games: An Empirical Analysis of the Japanese Video Game Industry

In this paper, we discuss the substitution effects between mobile games and console games. We estimate such effects by a fixed-effect regression with instrumental variables using panel data of about 100,000 observations. The results showed that the substitution effects of playing smart devices on 3DS, Wii, and PSP were recognizable, but did not have significant effects on PS3, and the substitution effects on PSP were very small. Therefore, mobile games had a substitution effect on casual console games, or on console games in which the play situation resembled mobile games. In addition, the substitution effects were at most about 0.1. The substitution effects were small. Our results indicate that mobile games represent the pioneers in the new market of gaming at least during our observation period. But new games and traditional games will coexist for a while.     

Non-traded inputs,interindustry flows,resource allocation and the ERP theory

This paper investigates the movement of gross outputs and resource allocation under the condition allowing for substitutability among various inputs within the framework of a simple general equilibrium model with both non-traded intermediate inputs and interindustry flows. Particular attention is paid to the sufficient conditions under which the gross output of the protected industry goes up and the industry attracts domestic factors under the Bhagwati-Srinivasan restriction on tariff change.     

Major Psychological Factors Affecting Acceptance of New Breeding Techniques for Crops

New plant biotechnologies called new breeding techniques (NBT), which will follow the present genetically modified (GM) technology, have appeared and are attracting attention worldwide. The first purpose of this study was to show consumer attitudes toward traditional plant breeding, GM, and NBT crops. The second purpose was to verify the validity of a psychological model determining the acceptance of NBT crops. A survey was conducted in Japan with 657 randomly selected adult participants. The results showed that perceived risk, perceived benefit, trust, sense of bioethics, anxiety, and anger play an important role in the personal and public acceptance of NBT and indicated that trust and anxiety are especially important factors in both situations.     

Employment tenure,job expectancy,and earnings profile in Japan

The purpose of this study is to examine the relationships between employment tenure and earnings profile in Japan. Since the Japanese labour market has recently experienced substantial changes, it is natural for the Japanese employment and compensation system to be influenced by such changes. In this study, the changes that have happened to the Japanese employment and compensation system in recent years have been considered empirically by focusing on the relationships between employment tenure and earnings profiles. To do this, a forward-looking variable called ‘expected job tenure (or job expectancy)’ is introduced and the effects of it on earnings profile.     

Using managers' expectations for ex-ante policy evaluation: Evidence from the COVID-19 crisis

Evaluation of the impacts of government policies during an economic crisis is often delayed until the outcomes are realized. Policies can be better guided if they can be evaluated amid a crisis, before the realization of outcomes. This study examines whether survey data on the expectations of small business managers can help evaluate two high-stake subsidies for firms amid the COVID-19 crisis in Japan, namely, Subsidy Program for Sustaining Businesses (SPSB) and Employment Adjustment Subsidy (EAS). We evaluate the accuracy of managers' expectations, estimate the impact of subsidies on the expected firm survival, and compare it with the estimated impact on realized survival. We find that the managers' expectations on their future sales, survival rate, and the possibility of receiving these subsidies predict the realized outcomes, although they were highly pessimistic about their survival rates. We find that the estimated impacts of the SPSB on the expected survival rates have the same sign as the estimated impact on the realized survival rates, but the size is more than twice because of the pessimism on survival. The estimated impacts of the EAS are both insignificant. Therefore, although its impact may be overestimated, managers' expectations are useful for selecting an effective policy.     

Long run equilibria in an asymmetric oligopoly

Summary. Consider an oligopolistic industry composed of two groups (or populations) of firms, the low cost firms and the high cost firms. The firms produce a homogeneous good. I study the finite population evolutionarily stable strategy defined by Schaffer (1988), and the long run equilibrium in the stochastic evolutionary dynamics based on imitation and experimentation of strategies by firms in each group. I will show the following results. 1) The finite population evolutionarily stable strategy (ESS) output is equal to the competitive (or Walrasian) output in each group of the firms. 2) Under the assumption that the marginal cost is increasing, the ESS state is the long run equilibrium in the stochastic evolutionary dynamics in the limit as the output grid step, which will be defined in the paper, approaches to zero.

Order aggressiveness, pre-trade transparency, and long memory in an order-driven market

Recent empirical research has documented that the state of the limit order book influences stock investors' strategies. Investors place more aggressive orders when the same side of the order book is thicker, and less aggressive orders when it is thinner. We conjecture and demonstrate that this behavior is related to long memories of trading volume, volatility, and order signs in stock markets. We investigate our conjecture in two types of artificial stock markets: a transparent market, in which agents observe all limit orders on both sides of the book and order volumes at those prices before they trade; and a less transparent market, in which agents observe only the best five bid and ask quotes with the depth available at these limit prices. The first market structure resembles certain actual stock exchanges in the level of pre-trade transparency, such as the Australian Stock Exchange, NYSE OpenBook, and the London Stock Exchange, whereas the second market structure is consistent with stock exchanges such as Euronext Paris, the Toronto Stock Exchange, the Tokyo Stock Exchange, and Hong Kong Exchanges and Clearing. We demonstrate that our long memory results are robust with different levels of pre-trade transparency, implying that the strategy constructed by the state of the order book is key for explaining long memories in many actual stock exchanges.
