Are the Japanese Selfish,Altruistic or Dynastic?

I analyse a variety of evidence for Japan and, where available, for the United States on bequest practices, the importance and nature of bequest motives, bequest division, the willingness of individuals to help others, etc., in order to shed light on which model of household behaviour applies in the two countries. My results suggest that the selfish lifecycle model is the dominant model of household behaviour in both countries but that it is far more applicable in Japan; that the dynasty model is also more applicable in Japan but is not of dominant importance even there; and, conversely, that the altruism model is far more applicable in the USA.

The turnpike of dynamic general equilibrium paths and its insensitivity to initial conditions

Asymptotic turnpike theorems in the case where the future is discounted are traditionally derived under the assumptions that a utility function is twice differentiable and that is Hessian is negative definite. Replacing these assumptions by a weaker one. I give a proof of the theorem simpler than existing ones.

Corporate Cash Holding in Asia

In this paper, we analyze the determinants of corporate saving in the form of changes in cash holdings for 11 Asian economies using firm‐level data from the Oriana Database for the 2002–2011 period. We find some evidence that cash flow has a positive impact on the change in cash holdings (i.e. that the cash flow sensitivity of cash is positive) and that the positive impact of cash flow on the change in cash holdings is larger and more significant in the case of smaller and presumably more constrained firms than in the case of larger and presumably less constrained firms in both developed and developing economies. Both of these findings corroborate the importance of financial constraints in Asian firms. In addition, we find that the cash flow sensitivity of cash declined after the global financial crisis and that Tobin's q has a positive impact on the change in cash holdings, especially in the case of larger and presumably unconstrained firms.     

Secure implementation in Shapley–Scarf housing markets

This paper considers the object allocation problem introduced by Shapley and Scarf (J Math Econ 1:23–37, 1974). We study secure implementation (Saijo et al. in Theor Econ 2:203–229, 2007), that is, double implementation in dominant strategy and Nash equilibria. We prove that (1) an individually rational solution is securely implementable if and only if it is the no-trade solution, (2) a neutral solution is securely implementable if and only if it is a serial dictatorship, and (3) an efficient solution is securely implementable if and only if it is a sequential dictatorship. Furthermore, we provide a complete characterization of securely implementable solutions in the two-agent case: a solution is securely implementable if and only if it is either a constant solution or a serial dictatorship.     

Expectation-driven fluctuations and welfare loss under free trade in two-country models

This paper investigates the interlinkage in the business cycles based on expectation-driven fluctuations of large-country economies in a free-trade equilibrium. We consider a two-country, two-good, two-factor general equilibrium model with sector-specific externalities. We show that some country's expectation-driven fluctuations can spread throughout the world once trade opens even if the other country has determinacy under autarky. We thus prove that under free trade, globalization and market integration can have destabilizing effects on a country's competitive equilibrium. Finally, we characterize a configuration in which opening to international trade improves the stationary welfare at the world level but deteriorates the stationary welfare of the country that imports investment goods and exports consumption goods. We conclude that in opposition to the standard belief, international trade might not be beneficial to all trading partners in the long run.     

A cross-country comparison of interindustry linkages and the role of imported intermediate inputs

This paper compares the patterns of intermediate input use, the levels of overall and domestic industrial linkages, and the role of imported intermediate goods in production among nine countries and over time, based on input-output data. Evidence on distinct differences in overall interindustry linkages and import contents between Korea and Taiwan on the one hand and Turkey, Colombia, and Mexico on the other are presented. The differences are then related to the differences in export structure and in trade and industrial policies adopted in each country.     

Factors in the Development of Trade Credit: Case Study of Provinces in China

Using Chinese province-level panel data for 2001-9, we investigate significant factors for the development of financial intermediation via trade credit in developing economies. First, we confirm that a competitive market environment, a well-functioning legal system, and greater bank loans for non-state-sector firms promote the development of trade credit in China. Conversely, corruption hinders its development. Second, we find that proper functioning of the legal system and bank lending to non-state-sector firms are highly likely to be the causes of the complex relationships between these determinants. Finally, we observe that an increase in the number of lawyers effectively improves the quality and function of the legal system, which, in turn, alleviates the harmful influence of corruption on trade credit development.
