　From the late 19th to the early 20th century, "crafts" were established as a genre of export products. In doing so, local products were redefined as "crafts" and presented to the world market as having "sanguralite" (unique individuality) while at the same time being versatile. In the latter half of the 19th century, the expansion of international trade led to the establishment of a global commodity chain, and the supply regions of primary (raw materials) and secondary (manufactured) products were identified. The latter half of the 19th century has been positioned as a period in which the regions of supply of primary products (raw materials) and secondary products (manufactured goods) were being identified. In contrast, the formation of the "craft" genre was a time of intermingling of diverse regional agendas and the reorganization and contextualization of the field at various levels, including global and regional and local.

　This study aims to quantify the effects of various policies toward insurgent armed groups on their activities (frequency of attacks, forms of attacks, geographic distribution, and probability of survival). Over the past decade, many studies have accumulated results on various counterinsurgency policies, such as targeted attacks against insurgent leaders and the outlawing of organizations by "designated terrorist lists. On the other hand, the analyses of impact assessments in existing studies have focused only on specific policies and have not sufficiently taken into account the impact of other counterinsurgency policies implemented concurrently. This study attempts to examine the effects of counterinsurgency policies more rigorously than before by classifying counterinsurgency policies into political, legal, and military approaches, compiling data on individual policies, and comprehensively understanding the various policies implemented by countries and international organizations. Through this analysis, we aim to provide useful scientific evidence for the selection and implementation of future counterinsurgency policies.

　Educational policies that serve as a bridge to employment, such as employment support through vocational training, are increasingly expected to be one of the safety nets for employment. However, despite such expectations, there are still many aspects of education leading to employment that have not been sufficiently studied. The purpose of this study is to conduct an empirical analysis from the viewpoint of safety nets, focusing on areas that have tended to be overlooked in the education system. Specifically, we focus on the roles played by public vocational training and junior colleges, and compare them with those of other countries. On the other hand, changes occurring at the secondary and tertiary education levels will also be discussed as factors that widen (or fix) the gap.

　The impact of uncertainty on firms' investment has been discussed for quite a long time. However, most of the existing studies focus on firms&rsquo ; investment in the domestic market, and there is still However, most of the existing studies focus on firms&rsquo ; investment in the domestic market, and there is still insufficient evidence on how uncertainty affects multinational firms ' behavior or foreign direct investment (FDI hereafter), let alone the within-firm adjustment mechanism Under such circumstances, it is natural that the uncertainty shock is not a natural one.
　Under such circumstances, it is natural to ask the following Research questions FDI : how is FDI affected by the macroeconomic uncertainty in the destination market, and through what kind of channels do multinational enterprises make subsequent adjustments? subsequent adjustments?
　Accordingly, the main objective Therefore, the main objective of this study is to Therefore, the main objective of this study is to make clear the mechanism I will investigate how the interactions between parent firms and their overseas affiliates evolve in response to the uncertainty shock, and potential channels of adjustment will be to clear the mechanism of how Japanese multinational firms respond to heterogeneous types of uncertainty in the destination market. I will investigate how the interactions between parent firms and their oversea affiliates evolve in response to the uncertainty shock, and potential channels of adjustment will be differentiated

An interesting trade structure has developed in East Asia over the past few decades. In particular, intra-regional trade accounts for more than half of total trade, and intermediate goods are a major part of this intra-regional trade. On the other hand, final goods play a more significant role in trade with the rest of the region. The purpose of this study is to analyze from an international macroeconomic perspective how this trade structure relates to economic interdependence among East Asian countries and the overall dynamism of the regional economy.

　The importance of a multilateral trade regime is growing from the perspective of addressing security issues and global environmental problems. In addition, the decline in trade costs associated with the increase in the number of free trade agreements has encouraged the development of cross-border economic activities, leading to the diversification of supply patterns of goods and services. Growth through the international economy from the development of global value chains in the Asian region reveals the need to address new international issues. Many countries today have signed regional economic agreements, affecting economic activities such as international intellectual property transactions and alliances, direct investment, and international mergers and acquisitions. International trade ties are important in Asia because they are believed to have a direct impact on corporate growth through the promotion of innovation and the efficient transfer of management resources. Therefore, understanding the causes of diverse supply patterns and establishing appropriate national systems (intellectual property law, corporate law, antitrust law, etc.) for IP transactions, finance, corporate governance, and market structure will not only achieve efficiency in establishing smooth market transactions, but will also play a major role in the economic development of the Asian region by fostering high value-added industries. This study aims to examine the role of the domestic market environment in the development of domestic institutions. This study analyzes the market structure under the interdependence of domestic institutions and international cooperation under the multilateral trade system, based on the recognition that the market environment is transformed in response to changes in domestic institutions. We will clarify the particularities and universality of domestic institutions and derive implications for the design of international institutions.

　This study examines the role of bargaining among economic agents in an economy where public goods are voluntarily supplied. To this end, we will apply a wide range of game theory methods, including non-cooperative game theory, cooperative game theory, and strategic cooperative game theory, to construct a theoretical analytical model and clarify the role of bargaining in applied problems, such as solving international environmental problems. Since Pareto inefficiency in resource allocation has long been known to be a problem in the provision of public goods, this study will examine the extent to which this problem can be resolved through voluntary negotiation, with a view to designing a negotiation mechanism to realize a more Pareto-superior allocation of resources. The objective of this study is to examine the impact of fiscal policy and the impact of the fiscal policy of the government.

The objective of this study is to quantitatively analyze how fiscal and monetary policies affect the Japanese economy using a heteroeconomic model. Following this academic stream, this study will quantitatively evaluate the impact of monetary and fiscal policies on the Japanese macroeconomy, paying attention to the aspects of income distribution and asset distribution. Specifically, we focus on the following four points: Laffer curve, Elasticity of Taxable Income (ETI), Financial Accelerator, and Fiscal Theory of the Price Level (FTPL). The objective of this study is to summarize the results and publish them in a peer-reviewed academic journal.

This study aims to clarify the motives for intergenerational asset transfers such as gifts and inheritances within families (the estate motive) and the effects of gift and inheritance taxation on asset transfers, consumption and saving behavior, and labor supply. In recent years, in order to encourage the ubiquitous transfer of assets to the elderly, the basic inheritance tax exemption amount has been lowered and tax exemptions have been introduced for gifts of education funds from grandparents and parents to children and grandchildren. While these policies may have the effect of stimulating consumption, they have also been pointed out to have problems such as widening the education gap due to asset transfers among wealthier households and increasing tax avoidance by allowing trans-generational gifts (from grandparents to grandchildren). Based on this awareness of these issues, the purpose of this study is to clarify the effects of policies on intergenerational asset transfers from the perspective of efficiency and fairness (inequality) using individual data at the household and individual levels.

Since the 1990s, technological innovation and globalization have forced Japanese companies to restructure their businesses, and since 2000, Hitachi, Ltd. and Sony Corporation have been implementing the Kawamura Reform and Hirai Reform, respectively, and have successfully completed their management reforms. Nissan's Ghosn reform, which brought in capital and management from overseas, and Sharp's restructuring under the umbrella of Hon Hai are also examples. On the other hand, many companies such as Panasonic and Toshiba are still in the process of restructuring. If the need for drastic restructuring is correctly recognized, the readiness for large losses associated with restructuring should be reflected in management projections and other factors. The purpose of this study is to examine, from the perspective of behavioral corporate finance, the link between managerial behavioral bias, i.e., a naive outlook that believes in the revival of declining businesses by sticking to past successes rather than the need for drastic restructuring, and the long-term stagnation of the Japanese economy, and to encourage business restructuring that takes the correction of managerial behavioral bias into account We will attempt to analyze how corporate governance can be constructed.

　Japan's public debt (as a percentage of GDP) has skyrocketed due to the expansion of social security costs and the persistent budget deficit caused by the falling birthrate and aging population. Although various reforms have been proposed, including reducing social security costs and increasing taxes, fiscal and social security reforms and the correction of intergenerational disparities have not progressed easily. It has been pointed out that one of the reasons for this is the possibility that the "Silver Democracy Hypothesis," which states that politics gives priority to policies that take into consideration the elderly, who are in the majority, is also deeply related to this situation. It is necessary to consider the structure of public finance and social security systems that are compatible with demographic changes, including the electoral system and fiscal control, which are the foundation of democracy. In addition, some countries, including those in East Asia, are expected to undergo rapid demographic changes, and it is undeniable that these changes could have a significant impact on the economic, fiscal, and political systems of each country. Therefore, under the theme of demographic change and the institutional design of public finance and social security, this research project will conduct research from both empirical and theoretical economics, including the verification of the "Silver Democracy Hypothesis" and the direction of reform of electoral systems and fiscal controls. In doing so, he will also keep in mind issues and trends not only in Japan but also in other countries as he conducts his research.

The main cause of Japan's economic stagnation, known as the "lost 20 years," is the decline in the competitiveness of Japanese companies. While some companies are further increasing their competitiveness by successfully expanding overseas through direct investment, others are conversely losing competitiveness by failing in mergers and acquisitions, selling acquired companies, or withdrawing from local production. What is the difference between direct investment, which raises profits and increases a company's competitiveness, and direct investment, which fails and causes a company to withdraw, thereby undermining the competitiveness of the company? The academic question at the core of this study is to elucidate what kind of investment strategies firms use to increase their international competitiveness.
　This study introduces the perspective of firms' investment strategy type into the analysis of the impact and effect of "firm heterogeneity," which has been the focus of recent trade theory, on their overseas expansion patterns. Each firm has a different investment strategy depending on the characteristics of its main products and market environment, and direct investment adapted to this strategy is expected to bring higher profits and increase competitiveness. In this study, passive firms suffering from strategy failure are included in the analysis to examine the characteristics of their investment strategies and direct investment patterns, and to analyze how they lead to firm competitiveness.

Although agri-environmental policies are being developed in Japan, we are far from a situation where environmental considerations have become mainstream in agricultural production. This study will focus on the concept of agro-environmental governance as a framework for environmental conservation in the agricultural sector, and through comparisons between Japan and Europe, answer the question of what practical methods, policies, and institutions are needed to realize collaborative governance in Japan, including environmental NGOs, for environmental conservation in the agricultural sector.
