Transboundary Pollution in a Dynamic Game Model

We consider a dynamic game model in which N countries produce a single product that is not traded. Production results in emissions that accumulate a stock of pollution in each country. Households in each country derive utility from consuming the product but face costs depending on the level of the country-specific stock of pollution as well as the pollution stocks of the other countries. We distinguish three different cost scenarios. For all three, we show the existence of a Markov perfect equilibrium (MPE) and derive the collusive outcome. The MPEs are associated with the case where countries fail to coordinate their policies, while the collusive solutions correspond to the coordinated policy.

Time preference and two-country trade

We present a dynamic two-country model of international trade with endogenous time preference. We show that if the two countries have similar preferences, production technologies and labor endowments, there exists a unique and stable steady state such that both consumption and investment goods are produced in both countries. Unlike the case of constant time preferences, the steady state is independent of the initial international distribution of capital. We prove a dynamic Heckscher–Ohlin theorem such that the labor-abundant country exports the labor-intensive good.     

On the emergence of non‐profit orchestras

In the market for live classical music, a symphony orchestra typically has fixed costs that are high relative to demand, so that the demand curve lies entirely below the average cost curve (Baumol & Bowen, 1966)—a situation in which a for‐profit enterprise cannot survive. The present study aims to explain how a non‐profit orchestra can survive in such an adverse market environment by relying on private donations, even in the absence of altruism. We argue that a financially distressed orchestra may employ a strategy to impose a non‐profit distribution constraint on itself—thus becoming a non‐profit, tax‐deductible organization—and use its member musicians' worker surplus to produce donor privileges, which enables the orchestra to induce donations from an individually rational audience by taking advantage of a tax deduction scheme. With this strategy, the orchestra can successfully extract consumer surplus from the audience to offset its loss.     

Endogenous business cycles in a perpetual youth model with financial market imperfections**

An economy in which entrepreneurs and financiers interact with each other through an imperfect financial market is investigated by applying a dynamic general equilibrium theory. In each period, there is a certain probability of each entrepreneur's life ending, and a certain number of entrepreneurs are newly born. Although entrepreneurs are potential capital producers, they receive an idiosyncratic productivity shock in each period. Therefore, entrepreneurs who draw higher productivity become capital producers and those who draw lower productivity become lenders. Financiers do not have an entrepreneurial talent for capital production, and thus they lend their assets in the financial market to acquire an interest income. In equilibrium, deterministic endogenous business cycles can occur at the intermediate level of financial constraints.     

WHAT EXPLAINS THE DIFFERENCE IN THE EFFECT OF RETIREMENT ON HEALTH? EVIDENCE FROM GLOBAL AGING DATA

This paper analyzes the reasons for differences in the estimated effect of retirement on health in previous studies. We investigate these differences by focusing on the analysis methods used by these studies. Using various health indexes, numerous researchers have examined the effects of retirement on health. However, there are no unified views on the impact of retirement on various health indexes. Consequently, we show that the choice of analysis method is one of the key factors in explaining why the estimated results of the effect of retirement on health differ. Moreover, we re‐estimate the effect of retirement on health by using a fixed analysis method controlling for individual heterogeneity and endogeneity of the retirement behavior. We analyze the effect of retirement on health parameters, such as cognitive function, self‐report of health, activities of daily living (ADL), depression, and body mass index in eight countries. We find that the effects of retirement on self‐report of health, depression, and ADL are positive in many of these countries.     

Not just financial support? Another role of public subsidy in university–industry research collaborations

Management of university–industry research collaboration (hereafter UIC) is the key to its success. In this respect, government can play an essential role in UIC. A public subsidy for research and development (hereafter R&D) is not only an important financial support for UIC but may also serve as a useful means of promoting trust among UIC members, resulting in higher innovation performance. However, few empirical studies have investigated the role a public R&D subsidy plays in promoting trust in UIC. To this end, by using original survey data, this study examines empirically whether a public R&D subsidy for UIC contributes to trust formation and, thus, to higher innovation performance based on trust. Our findings suggest that a public R&D subsidy promotes trust formation, which then increases the innovation performance of UIC participants, partially mediating the more direct effects of R&D subsidy on innovation performance.     

Foreign ownership,human capital,and the structure of wages in Japan

We examine the differences in the structure of wages between domestic and foreign-owned establishments in Japan. We use high-quality datasets from the Japanese government and construct a large employer–employee matched database consisting of 1 million workers in 1998. Our results confirm that foreign-owned establishments in Japan pay higher wages. We estimate that one percentage increase in foreign-ownership share of equity raises wages by 0.3%. We surmise that this foreign-ownership wage premium can be explained, at least in part, by compensating wage differentials. Workers in foreign-owned establishments are not protected by lifetime employment. They receive higher compensation for being exposed to higher risk and forfeiting their employment security. We also find that in foreign-owned establishments, wages are determined more by general skills, and less by firm-specific skills. These effects become more pronounced among establishments with a higher share of foreign ownership. The gender wage gap is considerably smaller among foreign establishments. Given the lack of long-term prospects for women in the Japanese labor market, foreign-owned establishments may be one source of ‘brain drain’ for highly skilled women there.     

Production externalities and local dynamics in discrete-time multi-sector growth models with general production technologies

The present paper examines the dynamic properties of discrete-time, multi-sector growth models in the presence of sector-specific externalities. It extends the literature by allowing for multiple capital good sectors with general social constant returns production technologies. We establish conditions for the steady-state equilibrium to be locally determinate or locally indeterminate, depending crucially on the ratios of the social to private marginal products and the number of capital good sectors. We show that when the ratios of the social to private marginal products are uniform across all sectors, the steady state is always locally determinate in a two-sector model, although local indeterminacy might still arise when the economy features more than two sectors.
