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. 相似文献

We examine the demand for underwriting and its effect on equilibrium in an insurance market in which insureds know their risk type, but insurers do not. Our analysis indicates that a set of policies including one that requires buyers to take an underwriting test can constitute a full coverage Nash equilibrium when perfect classification is possible. We also find that underwriting equilibria, in which low risks obtain greater coverage than they would without underwriting, widely exist in a Wilsonian market with nonmyopic insurers. Our findings provide a potential explanation for why empirical evidence on adverse selection is mixed. 相似文献

Pacific Asia is deep rooted in its cultural heritage and historical background, which have set the tone for regions success. These same factors also have created rather different trading practices, compared with those of the West — practices that are less transparent and full of hidden private trade barriers.
Interdependence within the region suggests integration, but Pacific Asia has taken a course of non-exclusive cooperation rather than following the exclusive course of the European Community (EC) and of the North American Free Trade Agreement (NAFTA). The latter two trade blocs threaten the continued success and development of Pacific Asia. Although the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) sends relief, fostering a cooperative rather than a retaliative Asian Pacific Economic Cooperation (APEC) organization offers the most promise. 相似文献

This paper constructs a heterogeneous agent overlapping generations model with bequests and inter vivos transfers. In the model, households in the same family line behave strategically to determine their consumption, working hours, gifts, and savings. Calibrating the model to the U.S. economy, the paper measures time preference and parental altruism consistent with the economy's capital-output ratio and the size of intergenerational transfers. The model with intergenerational transfers better explains, although not fully, the wealth distribution of the United States. The paper also analyzes the effects of government policy changes on wealth accumulation, distribution, and social welfare.

Summary In a two-period sunspot economy with inside money andS possible realizations of the sunspot, we prove that, genetically in the space of utility functions, there areS — 1 degrees of real indeterminacy. This result generalizes the previously known result for sunspot models that, generically in endowments, there is at least one degree of real indeterminacy. The proof involves showing that generically the equilibrium allocation is different across states for some household. This property allows us to perturb the utility function in a simple way and to apply standard transversality arguments to prove our main theorem.We would like to thank David Cass, Atsushi Kajii, Michael Mandler and Paolo Siconolfi for helpful discussions. 相似文献
